Each single use SILSTM Hand Instrument contains a pistol grip, a rigid shaft with an articulating and rotating end effector, and opposing jaws or an electrocautery hook at the distal end.
The clincher, dissector, grasper, and shears contain opposing jaws to manipulate tissue, and the dissector, L-hook, and shears administer electrocautery. The end effector of each instrument articulates when the handle is deflected relative to the shaft and rotates when a rotation wheel is turned.
The provided text describes a 510(k) summary for several endoscopic hand instruments (SILS™ Clincher, Dissector, Grasper, L-Hook, and Shears). This type of submission focuses on demonstrating substantial equivalence to a predicate device rather than comprehensive clinical studies proving specific performance criteria in a clinical setting. Therefore, many of the requested details, particularly those related to AI algorithm performance studies, will not be present in this document.
Here's a breakdown based on the provided text:
Acceptance Criteria and Device Performance
The document does not explicitly state "acceptance criteria" in a quantitative performance metric sense (e.g., sensitivity, specificity, accuracy thresholds). The acceptance criteria for a 510(k) submission like this revolve around demonstrating substantial equivalence to legally marketed predicate devices in terms of indications for use, technological characteristics, and safety and effectiveness.
The "performance data" mentioned refers to in-vitro and in-vivo testing to support the intended use and biological evaluation in accordance with ISO 10993-1:2003 for patient contact materials. However, specific quantitative results or how these results meet pre-defined acceptance criteria are not detailed in this summary.
Table of Acceptance Criteria and Reported Device Performance (as inferred from the 510(k) context):
| Acceptance Criteria Category | Specific Criteria (Inferred from 510(k)) | Reported Device Performance (as stated in document) |
|---|---|---|
| Intended Use | Device performs functions described in Indications for Use (clamping, grasping, dissecting, cutting, cautery in endoscopic procedures). | Stated application in a variety of endoscopic, gynecological, and general laparoscopic procedures for tasks like clamping, grasping, dissecting, cutting, and cautery. |
| Technological Equivalence | Similar design principles (pistol grip, rigid shaft, articulating/rotating end effector, opposing jaws/electrocautery hook) to predicates. | The clincher, dissector, grasper, and shears contain opposing jaws. Dissector, L-hook, and shears administer electrocautery. End effector articulates and rotates. |
| Biocompatibility | All patient contact materials comply with ISO 10993-1:2003. | "All patient contact materials in the SILSTM Hand Instruments have been evaluated in accordance with ISO 10993-1: 2003, Biological Evaluation of medical devices -- Part 1: Evaluation and Testing." |
| Safety & Effectiveness | Evidence of safe and effective operation for intended use (e.g., mechanical integrity, electrical safety for cautery). | "In-vitro and in-vivo testing has been performed in support of the intended use of these devices." (No specific results provided in this summary). |
Study Details (Based on available information in the document)
Since this is a 510(k) summary for conventional surgical instruments, there is no mention of an AI-powered device or associated studies. Therefore, many of the questions related to AI performance, ground truth, and expert evaluation are not applicable.
-
Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):
- Not Applicable / Not provided. The document refers to "in-vitro and in-vivo testing" but does not specify sample sizes, provenance, or whether the data was retrospective or prospective. This kind of detail is typically found in the full test reports, not a 510(k) summary.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):
- Not Applicable. As this is not an AI device, there's no concept of establishing "ground truth" by experts in this context for diagnostic performance.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not Applicable. This is relevant for diagnostic studies with human readers or AI.
-
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:
- No. This document does not mention an MRMC study or AI assistance.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- No. This is not an AI algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not Applicable. For mechanical surgical instruments, "ground truth" would relate to successful mechanical operation, tissue manipulation, and safety, assessed through engineering tests, pre-clinical models (in-vitro/in-vivo), and potentially clinical observations, not derived from expert consensus on images or pathology.
-
The sample size for the training set:
- Not Applicable. There is no AI model mentioned, thus no training set.
-
How the ground truth for the training set was established:
- Not Applicable. There is no AI model mentioned, thus no training set ground truth.
§ 876.1500 Endoscope and accessories.

Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope.
