An independent testing dataset containing videos was used to verify that the model performance (lower bound of the 95%CI for AP and AR) is compliant with our specification when using data including brands unseen during training/tuning.

Performance Testing

Design verification testing included the following:

  • Payload Capacity
  • Malformed Input
  • Force Accuracy
  • Emergency Stop
  • Hold Position Accuracy
  • IFU Inspection
  • Positioning Guidance & Collision Detection
  • System Positioning Accuracy
  • Bedside Joint Control Accuracy
  • End to End Workflow
  • Design Inspection
  • System Setup
  • System Latency
  • Electro-Cautery Compatibility
  • System Endurance
  • Cybersecurity
  • System Data Logging
  • System Connectivity
  • System Cloud Data
  • OS
  • ScoPilot Motion Performance
  • ScoPilot Vision Performance

Design validation testing and usability validation were not performed since the modification is not user-facing, does not add or modify risks, and does impact the clinical safety and performance of the Maestro System (K242323), nor the user interface or user tasks.

Predetermined Change Control Plan for ScoPilot

The detailed description of the planned modifications, testing methods, validation activities, performance requirements, and communication to users are summarized in the table below:

Planned modificationsTest Methods and Validation ActivitiesCommunication to users, as needed
Modification retraining the ML model with the addition of newly acquired data enables it to detect surgical instrument classes already claimed, and an increased variety of other brands in the video feed more accurately.The verification and validation activities are identical to the previously cleared instrument classes with equivalent performance metrics as outlined in the Modification Protocol.The labeling will be reviewed and updated as needed, in accordance with the authorized PCCP, to provide users with current information regarding the ScoPilot upgrade.
Users will be notified of the ML model update, by receiving a release note and the new user manual, and by the intervention of a Moon employee to install the new software version
Modification adding surgical cautery hooks to the ML model class hooks as another surgical instrument class.

Summary
