The Val Med Nurse's Assistant is intended to be used to turn on and off and adjust certain settings of endoscopic and surgical cameras, surgical lamps, and operating room ("O.R.") lights, and to operate VCRs, monitors, video printers, radios, and CD players.
The Val Med Nurse's Assistant is indicated for use in general, cardiovascular, ENT, gastroenterology, urology, plastic, obstetrics, gynecology, and orthopedic surgery, and general thorascoscopy, general cardiothoracic surgery, general laparoscopy, nasopharyngoscopy, ear endoscopy, and sinuscopy. A few examples of the more common surgical procedures where this system could be used are laparoscopic cholecystectomy, laparoscopic hernia repair, laparoscopic appendectomy, laparoscopic pelvic lymph node dissection, laparoscopically assisted hysterectomy, laparoscopic and thorascopic anteriorspinal fusion, decompression fixation, wedge resection, lung biopsy, pleural biopsy, dorsal sympathectomy, pleurodesis, internal mammary artery dissection for coronary artery bypass, coronary artery bypass grafting where endoscopic visualization is indicated, examination of the evacuated cardiac chamber during performance of valve replacement, arthroscopic meniscus repair, anterior cruciate ligament repair and associated procedures.
The Val Med's Nurse's Assistant is a computer with a monitor and touch screen that a nurse uses in the operating room to activate and control the following equipment: (1) surgical cameras, including an endoscopic camera; (2) room or surgeons' nurses' lounge cameras ("operating room cameras"); (3) surgical lights; (4) room lights; (5) a VCR; (6) a video printer; (7) video monitor(s); (8) a radio; and (9) a CD player. Val Med's Nurse's Assistant controls one or more electrical dimmer switches, which in turn control the surgical lights.
The furnished text describes a 510(k) premarket notification for the "Val Med Corporation Nurse's Assistant O.R. Control System." This document is a regulatory submission to the FDA, asserting substantial equivalence to existing predicate devices. It does not present a study with specific acceptance criteria and performance data in the way typically found for AI/ML-driven medical devices or devices where quantitative performance metrics are critical for safety and effectiveness.
Instead, the document focuses on demonstrating that the device meets safety standards and has similar technological characteristics and intended uses as predicate devices. The "Performance Data" section specifically references compliance with recognized electrical safety and software standards, which are a form of acceptance criteria for medical devices, but not in the format of a clinical performance study.
Here's an analysis based on the information provided, highlighting why certain requested sections cannot be fulfilled based on this document:
1. A table of acceptance criteria and the reported device performance:
| Acceptance Criteria (Compliance with Standards) | Reported Device Performance |
|---|---|
| Control Unit: EN 60601-1 Medical Electrical Equipment Part 1: General Requirements for Safety 4: Collateral Standard: Programmable Electrical Medical Systems | The Nurse's Assistant's control unit meets EN 60601-1. |
| Power Supply: UL 2601-1 "U.L. Standard for Safety for Medical Electrical Equipment - General Requirements for Safety" | The Nurse's Assistant's power supply meets UL 2601-1. |
| Controlling Software: ANSI standard 1375-221 | The Nurse's Assistant's controlling software meets ANSI standard 1375-221. |
Missing Information/Not Applicable:
The document does not describe acceptance criteria in terms of clinical performance metrics (e.g., sensitivity, specificity, accuracy, or other quantitative measures of how well the device performs a specific diagnostic or therapeutic function). This is because the Nurse's Assistant O.R. Control System appears to be a control interface and integration system, not a device directly performing diagnostic analysis or treatment requiring such performance metrics. Its "performance" is primarily defined by its ability to reliably control other medical equipment and adherence to safety and software standards.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
This information is not provided because the document describes compliance with engineering and software standards, not a clinical study on a patient population. There is no "test set" in the context of clinical data.
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):
This information is not provided. Ground truth, in the context of clinical or diagnostic performance, is not applicable to the type of device and submission described.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
This information is not provided. Adjudication methods are relevant for clinical studies establishing ground truth, which is not applicable here.
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:
This information is not provided. MRMC studies are used for evaluating diagnostic or interpretive AI systems, which this device is not. The Nurse's Assistant is an O.R. control system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
This information is not provided. This concept is relevant for AI/ML-driven diagnostic devices. The Nurse's Assistant is a control system that integrates human interaction.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
This information is not provided. Ground truth, in the clinical/diagnostic sense, is not applicable to this device's regulatory submission.
8. The sample size for the training set:
This information is not provided. Training sets are relevant for AI/ML models. This device is a control system, not an AI/ML diagnostic or predictive tool.
9. How the ground truth for the training set was established:
This information is not provided. Not applicable for the reasons stated above.
Summary of Device and Performance:
The Val Med Corporation Nurse's Assistant O.R. Control System is a computer-based system with a monitor and touch screen intended to control various pieces of operating room equipment, including endoscopic and surgical cameras, surgical lamps, O.R. lights, VCRs, monitors, video printers, radios, and CD players.
Its "performance" as described in this 510(k) submission is solely based on its compliance with established safety and software standards:
- EN 60601-1: General Requirements for Safety of Medical Electrical Equipment, with a specific collateral standard for Programmable Electrical Medical Systems. This ensures the electrical safety and basic functional safety of the control unit.
- UL 2601-1: U.L. Standard for Safety for Medical Electrical Equipment, ensuring the power supply meets safety requirements.
- ANSI standard 1375-221: For the controlling software, indicating adherence to a relevant software development or quality standard.
The submission demonstrates substantial equivalence to predicate devices (e.g., Computer Motion's Hermes, Olympus EndoAlpha, Karl Storz KSEA SCB-RUI) based on similar intended use, indications for use, and technological characteristics. The document does not describe any studies involving clinical performance data, patient outcomes, or expert interpretations because the device's function is to control and integrate other equipment, not to perform diagnostic or therapeutic interventions requiring such clinical performance validation.
