TMINI Miniature Robotic System

The THINK Surgical TMINI Miniature Robotic System is designed as a stereotaxic instrument to assist surgeons in achieving precise implant component placement during total knee replacement (TKA) surgeries. It operates by utilizing preoperative CT scans for surgical planning and guiding a robotically controlled hand-held tool within software-defined spatial boundaries, enhancing surgical accuracy and consistency.

The THINK Surgical, Inc.'s TMINI Miniature Robotic System, a Class II stereotaxic instrument, underwent a regulatory review and was determined to be substantially equivalent for its intended indications for use. This regulatory milestone permits the system's marketing, provided the manufacturer adheres to general controls, including annual registration, device listing, good manufacturing practice, and accurate labeling, alongside other obligations like the Quality System regulation and Unique Device Identification System rule. The TMINI system is specifically indicated for total knee replacement (TKA) surgery, where it functions by providing surgeons with software-defined spatial boundaries and reference information for precise knee implant component placement. Its methodology involves leveraging preoperative CT scans for detailed surgical planning and then guiding a robotically controlled hand-held tool. Recent enhancements include updates to the TPLAN Planning Station's algorithms for segmentation, improved DICOM data handling, implant display, and cybersecurity, plus a new web-based application for remote surgical plan review. Performance testing and risk analysis have confirmed that these modifications do not alter the system's core function, indications, or introduce new safety or effectiveness concerns.
