BITECH BIPOLAR SCISSORS
BiTech bipolar scissors are designed for dissecting, cutting and bipolar coagulation of tissue during general surgical procedures.
The BiTech Bipolar Scissors has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures and should not be used for these procedures.
BiTech bipolar scissors enable cutting and dissection with simulataneous bipolar coagulation. They can also be used for precise pinpoint or zone coagulation of blood-vessels and tissue. The various working lengths allow the scissors to be used for a large number of applications in open surgery.
A petented construction priciple, which was developed by Dr. J. Manushakian*, ensures that the scissors are both easy to use and to repair. The electrical contacts for both scissor blades are conducted via one section of the handle, i. e. the connection cable only needs to be attached to one ring, which significantly reduces reference duriong handling. The scissor blades are flexibly joined by means of a standard steel scissor screw which does not need to be insulated and, as a result, is not subject to wear.
The provided document describes a 510(k) notification for the BiTech Bipolar Scissors. A 510(k) submission primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting new clinical study data with specific acceptance criteria and performance metrics in the way a novel device might.
Therefore, the document does not contain the detailed information required for the requested output regarding acceptance criteria and the comprehensive study that proves the device meets those criteria. Specifically:
- No specific acceptance criteria are listed for device performance in terms of accuracy, sensitivity, specificity, etc.
- No study is described that details a test set, training set, ground truth establishment, or expert adjudication for performance evaluation.
- There is no mention of a multi-reader multi-case (MRMC) comparative effectiveness study or a standalone algorithm-only study.
Instead, the submission relies on demonstrating compliance with recognized performance standards for safety and electrical equipment, and stating substantial equivalence to existing devices.
Here's what can be extracted from the document, tailored to the spirit of your request where possible, but acknowledging the limitations of this type of submission:
1. A table of acceptance criteria and the reported device performance
Acceptance Criteria Category | Specific Standard/Requirement | Reported Device Performance / Compliance |

Summary of the Study/Evidence:
The "study" in a 510(k) submission like this is primarily a bench-testing and documentation effort to demonstrate:
- Compliance with recognized electrical and safety standards: DIN EN 60601-1, DIN EN 60601-2-2, and ANSI/AAMI HF18-2001. This would involve testing the device against the specific requirements and clauses within those standards.
- Substantial equivalence to legally marketed predicate devices: Ethicon (K981361) and Enable (K972558). This involves comparing the technological characteristics, intended use, and performance claims of the BiTech Bipolar Scissors to these established predicates. The document implies that the "patented construction principle" and how electrical contacts are conducted are key differentiating features, but these are presented as improvements in usability and repair, not as fundamentally altering the safety or efficacy compared to predicates for the stated intended use.
- Provision of validated user instructions: For cleaning, maintenance, and sterilization, ensuring the device can be safely and effectively prepared for use.
The FDA's letter states: "We have reviewed your Section 510(k) premarket notification of intent to market the device...and have determined the device is substantially equivalent...to legally marketed predicate devices..." This confirms the FDA's acceptance of the manufacturer's demonstration of substantial equivalence based on the provided documentation and compliance with the mentioned standards.

BIPOLAR GRASPER AND BIPOLAR SCISSORS FOR THE ZEUS MICROWRIST SURGICAL SYSTEM
The Bipolar Grasper and Bipolar Scissors are instruments used with the ZEUS® MicroWrist™ Surgical System. The Bipolar Grasper is intended to grasp, dissect, and coagulate tissue. The Bipolar Scissors provide mechanical cutting and bipolar coagulation. These bipolar instruments augment the means of performing electrosurgical procedures with the ZEUS® MicroWrist™ Surgical System.
This premarket notification adds a bipolar grasper and bipolar scissors to the ZEUS® MicroWrist™ Surgical System. These surgical instruments are used in conjunction with an electrosurgical generator unit (ESU), and they augment the means of performing electrosurgical procedures with the ZEUS® MicroWrist™ Surgical System. These devices are additions to the MicroAssist 100 line of ZEUS surgical instruments. MicroAssist instruments consist of commercially available hand-held devices that have been modified in order to be attached to the ZEUS arm. As with all MicroAssist instruments, the distal end that is used to perform surgical tasks remains unchanged from the hand-held version. The ZEUS® MicroWrist™ Surgical System, consisting of a surgeon console and three table-mounted arms, serves as a platform for holding, positioning, and manipulating endoscopic instruments in order to perform selected surgical tasks. One arm of the ZEUS System incorporates the AESOP® endoscope positioner which provides the surgeon with a steady view of the internal operating field. The HERMES® O.R. Control Center, which uses voice-recognition technology to control devices outside the sterile field, is a standard component of the ZEUS System.
The provided document describes a 510(k) summary for Bipolar Grasper and Bipolar Scissors for the ZEUS® MicroWrist™ Surgical System. This submission focuses on establishing substantial equivalence to existing predicate devices rather than proving performance against specific acceptance criteria through a clinical study with defined performance metrics.
Therefore, many of the requested elements for a study that "proves the device meets the acceptance criteria" are not applicable to this type of regulatory submission. The document reports on non-clinical tests to demonstrate substantial equivalence, not a clinical trial with specific performance endpoints.
Here's an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
Not Applicable (N/A) in the context of specific performance metrics.
This 510(k) submission is for substantial equivalence. The "acceptance criteria" are implicitly met by demonstrating that the new devices are "substantially equivalent in terms of size, shape, function, activation, and intended use to the predicate devices cited." The "reported device performance" is that these characteristics are maintained, even when manipulated by the robotic system.
Acceptance Criteria (Implicit) | Reported Device Performance |
---|---|
Primary difference from predicate devices is manipulation method (robotic vs. hand-held). | Confirmed: "The primary difference between the subject devices and the predicate devices is that the predicates are hand-held instruments while the subject devices are positioned and manipulated by the ZEUS® MicroWrist™ Surgical System." |
Maintained fundamental characteristics (size, shape, function, activation, intended use) compared to predicate devices. | Stated: "The Bipolar Grasper and Bipolar Scissors, instruments for the ZEUS® MicroWrist™ Surgical System, are essentially identical in terms of size, shape, function, activation, and intended use to the predicate devices cited." |
Also: "As with all MicroAssist instruments, the distal end that is used to perform surgical tasks remains unchanged from the hand-held version."
Conclusion: "Data provided in this submission indicate that the basic functional characteristics of these devices are substantially equivalent to the predicates." |
2. Sample Size Used for the Test Set and Data Provenance
Not directly applicable as a clinical "test set" demonstrating performance metrics.
The submission relies on non-clinical tests to establish substantial equivalence. The document does not specify a "sample size" for a test set in the way one would for a clinical performance study (e.g., number of patients or cases). The "data provenance" would be from internal engineering and bench testing, likely conducted by Computer Motion, Inc. There is no mention of country of origin for clinical data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
N/A. Ground truth from clinical experts is not relevant here as it's not a clinical performance study. The "ground truth" for substantial equivalence is based on engineering specifications and physical characteristics compared to predicate devices.
4. Adjudication Method for the Test Set
N/A. No adjudication method is described as there isn't a clinical test set requiring expert review or consensus.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
N/A. This device is a surgical instrument (bipolar grasper and scissors), not an AI-powered diagnostic or assistive tool for human readers. No MRMC study was conducted or is relevant.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
N/A. This device is a surgical instrument that is part of a surgical system controlled by a human surgeon (“ZEUS® MicroWrist™ Surgical System, consisting of a surgeon console and three table-mounted arms, serves as a platform for holding, positioning, and manipulating endoscopic instruments”). It is not an algorithm, and the concept of "standalone performance" for an algorithm is not applicable.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
For this 510(k) submission, the "ground truth" for demonstrating substantial equivalence is primarily based on:
- Engineering specifications and design characteristics of the new devices (Bipolar Grasper and Bipolar Scissors).
- Comparison to the known specifications and performance of the predicate hand-held devices (Lyons™ Dissecting Forceps and Evershears®).
- The fact that "the distal end that is used to perform surgical tasks remains unchanged from the hand-held version" implies that the functional part of the device is identical to established predicate devices.
8. The Sample Size for the Training Set
N/A. As this is a 510(k) for surgical instruments demonstrating substantial equivalence through non-clinical testing, there is no "training set" in the context of machine learning or AI.
9. How the Ground Truth for the Training Set Was Established
N/A. See point 8.

EVEREST LP BIPOLAR SCISSORS AND GYRUS LP BIPOLAR SCISSORS
Mechanical cutting and electrosurgical coagulation of tissue during the performance of laparoscopic and general surgical procedures.
The device is a Class II medical device. The Everest LP Bipolar Scissors and Gyrus LP Scissors are a modification to the predicate device cleared under K904993. The Bipolar Bipolar LP Scissors are identical in construction (with the exception of shaft length) and in component materials when compared to the predicate device. The scissors blades are electrically isolated from each other enabling one blade to act as a return electrode, eliminating the need for a return pad. The modification has not altered the fundamental technology of the predicate device cleared under K904993. The intended use, electrosurgical coagulation and mechanical cutting during surgical procedures is similar to the predicate device cleared under K904993. The energy source, Bipolar Electrosurgical Energy, is the same energy type as used for the predicate devices.
The provided text is a 510(k) summary for the Everest LP Bipolar Scissors and Gyrus LP Bipolar Scissors. It discusses the device's substantial equivalence to a predicate device and its intended use. However, it does not contain information about specific acceptance criteria, a study proving the device meets those criteria, or any of the detailed aspects like sample sizes, expert ground truth, or AI performance that your request asks for.
The document states:
"The Bipolar Bipolar LP Scissors are identical in construction (with the exception of shaft length) and in component materials when compared to the predicate device. The scissors blades are electrically isolated from each other enabling one blade to act as a return electrode, eliminating the need for a return pad. The modification has not altered the fundamental technology of the predicate device cleared under K904993. The intended use, electrosurgical coagulation and mechanical cutting during surgical procedures is similar to the predicate device cleared under K904993. The energy source, Bipolar Electrosurgical Energy, is the same energy type as used for the predicate devices."
"In conclusion, as the design, materials of construction, function and intended use of the Modified LP Bipolar Scissors is similar to that of the predicate devices currently cleared, Gyrus Medical Inc. believes that no new issues of safety and effectiveness are raised and that the submitted device is substantially equivalent."
This indicates that the device was cleared based on substantial equivalence to an existing predicate device (K904993), rather than requiring a new clinical performance study with specific acceptance criteria as you've outlined. The FDA's 510(k) process often relies on demonstrating that a new device is as safe and effective as a legally marketed predicate device, without necessarily requiring new, extensive clinical trials for every submission, especially for modifications that don't alter fundamental technology.
Therefore, I cannot populate the table or answer the specific questions you've posed because the provided text does not contain that type of detailed study information. The clearance was based on the premise that the device is "substantially equivalent" to one already on the market, implying that its performance would be similar, and thus, specific performance metrics and studies to prove them are not detailed in this summary.

OSCAR BIPOLAR SCISSORS AND OSCAR BIPOLAR REUSABLE CARTRIDGES
The OSCAR™ Bipolar Scissors with OSCAR™ Bipolar Disposable Cartridges is intended to cut tissue and control bleeding through coagulation during open surgical procedures and in general surgery.
The OSCAR™ Bipolar Scissors is a reusable electrosurgical instrument consisting of an instrument handle with a pair of scissors blades which attaches to the OSCAR™ Bipolar Disposable Cartridges and an electrosurgical generator. Electric current flows between the electrodes in the cartridges and the stainless steel cutting surfaces of the blades. The electrosurgical generator controls the flow of the electric current down the electrode. The overall length of the device is between 4 and 11 inches. The power cord connecting the handle to the power control unit is approximately 120 inches. The blades are between 1 and 2 inches in length.
The surgeon places the opened scissors across the tissue to be cut and closes the scissors handle while moving the scissors across the tissue. Energizing the electrosurgical generator via the generator's footswitch, the surgeon can simultaneously cut and coagulate the target tissue. The surgeon can vary the current flow rate according to the tissue and the amount of bleeding encountered. The power setting for the OSCAR™ Bipolar Scissors is 20-30 watts.
Acceptance Criteria and Device Performance Study for OSCAR™ Bipolar Scissors with OSCAR™ Bipolar Disposable Cartridges (K981219)
Based on the provided 510(k) summary, the device's acceptance criteria and the study proving its performance are primarily established through a demonstration of substantial equivalence to legally marketed predicate devices. The document does not describe a traditional performance study with specific quantitative acceptance criteria for the OSCAR™ device itself, but rather relies on the equivalency to already approved devices.

BIPOLAR SCISSORS
The ENABLE Bipolar Scissors with ENABLE Bipolar Disposable Cartridges are intended to cut tissue and control bleeding through coagulation during general surgery.
The ENABLE Bipolar Scissors is a reusable electrosurgical instrument consisting of an instrument handle with a pair of scissors blades which attaches to the ENABLE Bipolar Disposable Cartridges and an electrosurgical generator. Electric current flows from the electrodes in the cartridges to the stainless steel cutting surfaces of the blades. The electrosurgical generator controls the flow of the electric current down the electrode. The overall length of the device is between 4 and 11 inches. The power cord connecting the handle to the power control unit is approximately 120 inches. The blades are between 1 and 2 inches in length.
The surgeon places the opened scissors across the tissue to be cut and closes the scissors handle while moving the scissors across the tissue. Energizing the electrosurgical generator via the generator's footswitch, the surgeon can simultaneously cut and coagulate the target tissue. The surgeon can vary the current flow rate according to the tissue and the amount of bleeding encountered. The power setting for the ENABLE Bipolar Scissors is 20-30 watts.
The provided text is a 510(k) summary for the ENABLE Bipolar Scissors with ENABLE Bipolar Disposable Cartridges. It focuses on establishing substantial equivalence to predicate devices rather than presenting a performance study with acceptance criteria.
Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving the device meets them, as this type of data is not present in the provided document.
The document discusses:
- Intended Use: To cut tissue and control bleeding through coagulation during general surgery.
- Product Description: A reusable electrosurgical instrument with disposable cartridges, connected to an electrosurgical generator, designed to simultaneously cut and coagulate tissue.
- Predicate Devices: Several other bipolar scissors (Symbiosis, Everest Medical, CardioThoracic Systems, Ethicon PowerStar) are listed as substantially equivalent in intended use, function, physical characteristics, materials, and sterilization method.
- Regulatory Classification: Class II.
- Power Setting: 20-30 watts for operation.
The document does not include:
- A table of acceptance criteria and reported device performance.
- Details about sample sizes for test sets, data provenance, or ground truth establishment.
- Information on expert involvement, adjudication methods, MRMC studies, or standalone algorithm performance.
- Sample sizes for training sets or ground truth establishment for training.
The 510(k) process primarily relies on demonstrating substantial equivalence to a legally marketed predicate device rather than comprehensive de novo clinical studies with pre-defined acceptance criteria for performance metrics.

CTS MIDCAB/SVH BIPOLAR SCISSORS
The CTS MIDCAB/SVH Bipolar Scissors is intended to cut tissue and control bleeding through coagulation, in general and cardiothoracic surgery, including minimally invasive direct coronary artery bypass ("MIDCAB") and saphenous vein harvesting procedures.
The CTS MIDCAB/SVH Bipolar Scissors is an electrosurgical instrument which consists of a pair of scissor blades which are connected to a handle instrument and an electrosurgical generator. Electric current flows from the electrode to the stainless steel cutting surface of the blades and from the stainless steel cutting surface of one blade to the stainless steel cutting surface of the other blade. The flow of the electric current down the electrode is controlled by the power generator. The overall length of the device, which consists of the handle, tube and blades, is approximately 13 inches. The power cord connecting the handle to the power control unit is approximately 120 inches. The blades are approximately 0.5 inches in length.
The surgeon places the opened scissors across the tissue to be cut and depresses the actuation lever while moving the scissors forward against the tissue. By energizing the power control unit on the actuation lever, the surgeon can simultaneously cut and coagulate the target tissue. Alternately, the power control unit may be controlled via a foot pedal. The surgeon can vary the current flow rate according to the tissue and the amount of bleeding encountered. The power setting used for the CTS Bipolar Scissors is 20-30 watts.
The CTS Bipolar Scissors is provided sterile, nonpyrogenic and for single use.
The provided text is for a 510(k) summary for a medical device (CTS MIDCAB™ /SVH™ Bipolar Scissors) and does not contain information about acceptance criteria or a study proving that the device meets such criteria. Typically, 510(k) summaries for surgical instruments like this focus on demonstrating substantial equivalence to predicate devices rather than presenting performance criteria and detailed study results that would be found for diagnostic devices or AI/ML-driven software.
Therefore, I cannot fulfill your request for the specific sections you've outlined based on the given information.
Here's why and what kind of information would be needed:
- Acceptance Criteria and Reported Device Performance: This would require a clearly defined set of performance metrics (e.g., cutting time, coagulation effectiveness, tissue damage assessment, safety parameters) with specific quantifiable targets and the results from testing to demonstrate achievement of those targets.
- Sample Size, Data Provenance, Experts, Adjudication, MRMC, Standalone, Ground Truth, Training Set: These are all components of a clinical or performance study that would establish the efficacy and safety of a diagnostic or AI/ML-enabled device. For a surgical instrument like the bipolar scissors, the "proof" often comes from bench testing, animal studies, and sometimes limited human use studies focused on safety and direct function, rather than large-scale diagnostic accuracy studies.
In the context of the provided 510(k) summary, the "study" is the substantial equivalence comparison to predicate devices, which relies on demonstrating similar intended use, technology, and performance, rather than an independent clinical trial with predefined acceptance criteria for novel performance.
