The ASC R-Port II Laparoscopic Access Device is intended for use as a multiple instrument and/or camera port during minimally invasive abdominal laparoscopic surgery.
The Advanced Surgical Concepts (ASC) R-Port II Laparoscopic Access Device is intended for use as a multiple instrument and/or camera port during minimally invasive abdominal laparoscopic surgery. The proposed ASC R-Port II Laparoscopic Access Device is identical in design to the R-Port Laparoscopic Access Device, which has been cleared for marketing under K070158. Two modifications have been made to the use of the proposed ASC R-Port II Laparoscopic Access device. ASC has made very minor changes to the indications for use and the recommended method for delivery of the device although the design of the device is identical to the one described in K070158. The proposed ASC R-Port II Laparoscopic Access Device and the original R-Port Laparoscopic Access Device are otherwise identical in design, mechanism of action and operating principles.
The proposed ASC R-Port II Laparoscopic Access Device is a laparoscopic instrumentation access port that is used to perform the same function as other port systems and standard trocars. The original R-Port was offered with four different Introducer components for deployment but the proposed ASC R-Port II is offered with only one Introducer and a new delivery method. The new recommended delivery method for the proposed ASC R-Port II consists of initially insufflating the abdomen using a standard Verres Needle before creating the port incision. This is common practice with standard trocar insertions. In addition, as described in K070158, the ASC R-Port II can also be deployed after the creation of a Hasson cut-down incision. This type of incision is also commonly used for the deployment of standard trocars. The Distal Ring of the ASC R-Port II is delivered through the Hasson incision using the Introducer component of the ASC R-Port II which is the same Injector Introducer cleared for marketing under K070158.
The ASC R-Port II Laparoscopic Access Port is a sterile, disposable laparoscopic instrument port which performs two functions, as follows:
- . It retracts a small abdominal incision to allow multiple laparoscopic instruments to pass through to the abdomen
- It ensures that pneumoperitoneum is maintained in the abdomen during the . surgical procedure whether or not a laparoscopic instrument is passing through the port
Like the predicate R-Port Laparoscopic Access Device, the ASC R-Port II Laparoscopic Access Device is comprised of the following:
- a retracting portion which retracts an abdominal incision to allow the passage of . laparoscopic instruments
- . a valve portion which maintains the pneumoperitoneum established for the surgical procedure
The provided text is a 510(k) summary for the Advanced Surgical Concepts (ASC) R-Port II Laparoscopic Access Device. It outlines the device's description, intended use, and substantial equivalence to predicate devices, but does not contain detailed information about specific acceptance criteria or the study data that would typically be associated with performance metrics for AI/ML devices.
Based on the information provided, here's what can be extracted and what cannot:
1. Table of Acceptance Criteria and Reported Device Performance:
The document does not specify numerical acceptance criteria or quantifiable device performance metrics for the ASC R-Port II Laparoscopic Access Device. This type of device (a laparoscopic access port) is a mechanical surgical instrument, not an AI/ML-driven diagnostic or prognostic tool. Therefore, its "performance" is generally assessed through functional verification and biocompatibility, rather than metrics like sensitivity, specificity, or AUC.
The document states:
"Biocompatibility and verification testing have been performed which demonstrated that the ASC R-Port II Laparoscopic Access Device functions as intended and is safe and effective for its intended use."
This confirms that testing was done to ensure the device met its functional requirements and safety profile, but the specific acceptance criteria (e.g., maximum leakage rate, force required for insertion, durability cycles) are not detailed in this summary.
2. Sample Size Used for the Test Set and Data Provenance:
The document does not mention a "test set" in the context of data for AI/ML evaluation. The performance testing referred to is for a mechanical medical device.
3. Number of Experts Used to Establish Ground Truth and Qualifications:
Not applicable. This is not an AI/ML device that requires human experts to establish ground truth for image interpretation or diagnosis.
4. Adjudication Method:
Not applicable. This is not an AI/ML device with a diagnostic output requiring adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
Not applicable. This is not an AI/ML diagnostic or assistive device.
6. Standalone (Algorithm Only) Performance:
Not applicable. This is a manual surgical instrument, not an algorithm.
7. Type of Ground Truth Used:
Not applicable in the context of AI/ML. The "ground truth" for a mechanical device would be its functional specifications and safety standards, confirmed by engineering tests and biocompatibility assessments.
8. Sample Size for the Training Set:
Not applicable. There is no AI/ML model to train for this device.
9. How the Ground Truth for the Training Set Was Established:
Not applicable. There is no AI/ML model to train for this device.
Summary of what the document does provide regarding performance and testing:
- Type of Testing: Biocompatibility and "verification testing."
- Purpose of Testing: To demonstrate that the device "functions as intended and is safe and effective for its intended use."
- Comparison Basis: Substantial equivalence to predicate devices (K070158, K010007, K032676, K010711). The primary predicate device is the R-Port Laparoscopic Access Device (K070158), with which the ASC R-Port II shares an identical design, mechanism of action, and operating principles, with only minor changes to indications for use and delivery method.
- Key Functions Tested (implied by device description):
- Retracting a small abdominal incision to allow multiple laparoscopic instruments to pass.
- Maintaining pneumoperitoneum in the abdomen.
Conclusion:
The provided 510(k) summary for the ASC R-Port II Laparoscopic Access Device describes a mechanical surgical instrument, not an AI/ML device. Therefore, the specific questions related to AI/ML performance metrics, sample sizes for test/training sets, expert ground truth, and comparative effectiveness studies with human readers are not applicable to this document. The "study" mentioned is general "performance testing" to ensure the device meets its functional and safety requirements, aligning with the regulatory pathway for substantial equivalence for a Class II medical device.
