The Intuitive Surgical Endoscopic Instrument Control System (da Vinci Surgical System, Models: IS4000 and IS4200) is intended to assist in the accurate control of Intuitive Surgical Endoscopic Instruments including rigid endoscopes, blunt and sharp endoscopic dissectors, scalpels, forceps/pick-ups, needle holders, endoscopic retractors, electrocautery and accessories for endoscopic manipulation of tissue, including grasping, cutting, blunt and sharp dissection, approximation, ligation, electrocautery, suturing, and delivery and placement of microwave and cryogenic ablation probes and accessories, during urologic surgical procedures, general laparoscopic surgical procedures, gynecologic laparoscopic surgical procedures, general thoracoscopic surgical procedures and thoracoscopically-assisted cardiotomy procedures. The system can also be employed with adjunctive mediastinotomy to perform coronary anastomosis during cardiac revascularization. The system is indicated for adult and pediatric use. It is intended to be used by trained physicians in an operating room environment in accordance with the representative, specific procedures set forth in the Professional Instructions for Use.
This 510(k) is for a labeling modification only, to include the following additional representative, specific procedure of "Appendectomy" under the cleared "general laparoscopic surgical procedures" Indications for Use of the da Vinci Xi Surgical System, Model IS4000 (K131861) and the da Vinci X Surgical System, Model IS4200 (K171294). There are no changes to the technological characteristics of the cleared da Vinci Xi or X Surgical Systems (Models IS4000 and IS4200) proposed in this submission. The da Vinci Xi and X Surgical Systems, Models IS4000 and IS4200, are software-controlled, electro-mechanical systems designed for surgeons to perform minimally invasive surgery. The Model IS4000 and Model IS4200 Surgical Systems consist of a Surgeon Console, a Patient Side Cart (PSC), and a Vision Side Cart (VSC) and are used with an Endoscope, EndoWrist Instruments, and Accessories.
This document, a 510(k) summary, details a labeling modification for the da Vinci Xi and X Surgical Systems to include "Appendectomy" under their cleared "general laparoscopic surgical procedures" indications for use. It is not a study demonstrating device performance or meeting acceptance criteria in the typical sense of a new device or a new algorithmic feature.
Therefore, many of the requested fields are not applicable in this context. This submission is for a procedural labeling change based on the existing safety and effectiveness of the device for similar procedures.
Here's a breakdown of the information that can be extracted, and where the requested information is not applicable:
1. Table of Acceptance Criteria and Reported Device Performance:
This document does not present acceptance criteria or reported device performance in the form of metrics (e.g., accuracy, sensitivity, precision) because it's a labeling modification for an existing device. Instead, the "acceptance criteria" here relate to demonstrating that appendectomy is equivalent in safety and effectiveness to already cleared procedures for the device.
| Acceptance Criteria (Demonstration Points) | Reported Device Performance (Argument presented in submission) |
|---|---|
| All procedural steps, surgical tasks, and instruments required to perform appendectomy are part of the umbrella procedure. | A comparison of surgical tasks performed with the da Vinci Systems for appendectomy shows no new surgical tasks are introduced compared to the colorectal umbrella procedure of Low Anterior Resection Total Mesorectal Excision (LAR/TME) and covered procedure Colectomy. |
| Appendectomy is less complex and less challenging than the umbrella procedure. | Explicitly stated as a condition met. |
| All anatomical structures encountered in appendectomy are encountered similarly in the umbrella procedure. | Explicitly stated as a condition met. (Appendectomy and LAR/TME / Colectomy employ the same surgical tasks in the same anatomical location of the abdomen). |
| Use of the device for appendectomy does not introduce any new issues of safety or effectiveness as compared to device usage in the cleared umbrella procedure. | The surgical risks associated with appendectomy (bleeding, infection, leak, stricture, bowel injury, injury to adjacent organs, perforation) are not different from those associated with LAR/TME and Colectomy. Therefore, the addition of appendectomy as a representative, specific procedure does not represent a change or modification in the device that could significantly affect the safety or effectiveness of the device, requiring no new clinical data or other validation/verification testing. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
Not applicable. No new test set or data was used because this submission is for a labeling modification based on the substantial equivalence of the procedure to already cleared procedures. The submission argues that appendectomy is covered under existing cleared procedures (LAR/TME and Colectomy) for which the device has already demonstrated safety and effectiveness.
3. 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. No new ground truth was established for a test set. The claim is based on the inherent surgical similarities between procedures already approved for the device.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. No adjudication method was used as there was no new test set requiring expert review.
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:
Not applicable. No MRMC comparative effectiveness study was done. This device is a surgical system, not an AI-assisted diagnostic or interpretative tool for human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This device is a surgical system that assists in controlling instruments. It is not an algorithm performing a task without human intervention. The submission focuses on the human surgeon using the device for a new procedure within its established capabilities.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
The "ground truth," in a conceptual sense for this submission, is the established surgical knowledge and practice regarding the equivalence of appendectomy to other laparoscopic procedures (LAR/TME and Colectomy) already cleared for the da Vinci systems. This is implicitly based on expert surgical opinion on procedural steps, required instruments, anatomical structures, and associated risks. No formal new "ground truth" for a study was established for this submission.
8. The sample size for the training set:
Not applicable. There is no training set in the context of this submission. The device itself has undergone extensive training (development and testing) prior to its initial clearance. This submission solely re-evaluates the scope of its cleared indications.
9. How the ground truth for the training set was established:
Not applicable. As there is no training set for this labeling modification, there is no ground truth established for it. The original "ground truth" for the device's development would have been established through a rigorous process of engineering, preclinical testing, and clinical trials for its initial clearance and prior modifications.
