SDC3 users are general surgeons, gynecologists, cardiac surgeons, thoracic surgeons, plastic surgeons, orthopedic surgeons, ENT surgeons, and urologists.

    Device Description

    The Stryker SDC3 HD Information Management System with wireless device control capability (herein referred to as 'proposed device') consists of the following:

    1. Stryker SDC3 HD Information Management System (SDC3) that consists of:
      a. A stand-alone console containing SDC3 software version 1.5 and above
      b. A device control package (contains optional software upgrade and a handheld Infrared (IR) remote control)
      c. A voice control package (contains optional software upgrade and a microphone/headset).
    2. The Universal Gateway System (Gateway) (acts as a medium for transferring medical device and non-medical device data).

    The proposed device is a modification of the Stryker SDC3 HD Information Management System (hereafter referred to as "predicate device", cleared under K121893) to add wired and wireless device control functionality via the Gateway. The wired device control feature (cleared under K121893) and the operating room documentation functionalities of electronically capturing, transferring, storing and displaying of medical device data (Class I device function) provided by the SDC3 remains the same compared to the predicate device. It should be noted that the device control functionality (both wired and wireless) of the proposed device only provides users with convenient, centralized control of connected (wired and wireless), compatible medical devices. The SDC3 accesses existing controls within each device and is secondary to the built-in control interface that is already on each device.

    AI/ML Overview

    The provided text describes the Stryker SDC3 HD Information Management System with Wireless Device Control Capability (K160332), a modification of a predicate device (K121893) to add wired and wireless device control functionality via a Universal Gateway System. The document focuses on regulatory compliance and the safety and effectiveness of the new wireless functionality.

    However, the document does not contain the level of detail requested for a typical study proving a device meets acceptance criteria, particularly for an AI/ML-based diagnostic device where performance metrics like sensitivity, specificity, or AUC are expected. This submission is for a device providing enhanced control and information management in a surgical setting, not a diagnostic or AI-driven decision-making tool. Therefore, the "acceptance criteria" and "device performance" are related to its functionality, reliability, and safety in controlling other medical devices and handling data, rather than diagnostic accuracy.

    Here's an attempt to extract and interpret the information based on the provided text, acknowledging its limitations for the requested format:

    Acceptance Criteria and Reported Device Performance

    Given the nature of the device (a control and information management system with new wireless capabilities), the "acceptance criteria" are implied by the verification and validation activities described, focusing on functionality, safety, and reliability of the wireless communication and device control. No specific numerical thresholds (e.g., >90% accuracy) for clinical performance are applicable or provided.

    Acceptance Criteria Category (Implied)Specific Tests / Performance Reported

    Study Details (based on interpretation of provided text)

    1. Sample size used for the test set and the data provenance:

      • The document does not specify a "test set" in terms of patient data or clinical images, as this is neither an AI/diagnostic device nor a device that processes such data for clinical output.
      • The testing described is focused on engineering verification and validation of the device's functionality, connectivity, security, and performance in various operational environments (e.g., co-existence with other wireless devices).
      • No information on data provenance (e.g., country of origin, retrospective/prospective) is applicable or provided, as no clinical data set is referenced for performance evaluation.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • This question is not applicable. There is no "ground truth" to be established by clinical experts for the type of device tested. The "ground truth" for the tests performed would be the engineering specifications and expected functional behavior (e.g., "does the device turn on/off the connected medical device as commanded?", "is the wireless connection stable?").
    3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

      • Not applicable. No clinical test set requiring adjudication by multiple readers is mentioned.
    4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

      • No, an MRMC comparative effectiveness study was not done. This type of study is typically performed for diagnostic devices where human readers interpret medical images or data, and their performance with and without AI assistance is compared. The Stryker SDC3 is a control and information management system, not a diagnostic tool.
    5. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

      • This concept is largely not applicable in the context of this device. The core functionality is human-in-the-loop (surgeon/personnel controlling devices via SDC3). However, the "Benchmarking Test" did verify latency and data accuracy for wireless device control data transmission (algorithm/system performance) compared to a wired system, which could be considered a form of standalone performance evaluation for its wireless data transfer capabilities. The "SDC3 and Gateway Accuracy and Reliability Coexistence Report" also evaluated the system's performance in a standalone manner regarding its data transmission.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

      • Not applicable in the clinical sense. The "ground truth" for the engineering performance tests performed would be defined by the device's design specifications and expected functional outcomes, verified through controlled experiments and measurements. For example, for the "Timing Test," the ground truth would be the specified connection/disconnection times.
    7. The sample size for the training set:

      • Not applicable. This device is not an AI/ML model that would typically have a "training set" of clinical data to learn from for diagnostic or predictive purposes. The software development follows a standard life cycle process (IEC 62304), which includes verification and validation but not machine learning training.
    8. How the ground truth for the training set was established:

      • Not applicable, as no training set (in the AI/ML sense) is mentioned or implied for this device.
