Development of the TMINI™ Miniature Robotic System

Our client asked:

Our client, THINK Surgical, selected Sagentia Innovation as their primary development partner of the TMINI™ Miniature Robotic System following THINK Surgical’s initial concept through to transfer to manufacture. The TMINI system includes a wireless robotic handpiece that assists Orthopaedic surgeons in performing Total Knee Replacement (TKR). The TMINI robotic handpiece automatically compensates for surgeon hand movement to locate bone pins along precisely defined planes. Cutting guides are connected to the bone pins for accurate bone resection and implant positioning.

 

The project story:

  • Turnkey subsystem development (TMINI robotic handpiece, battery charger) encompassing electrical, mechanical, and software design, from concept through to verification, pilot builds and transfer to manufacture
  • Responsibility for overall program management, system architecture, integration approach, and issue resolution
  • Design controls, risk management and DHF management from overall system level to subsystem level
  • Responsibility for overall human factor engineering activities and associated documentation to IEC62366
  • Development of assembly and calibration fixtures (with associated software), and end-of-line manufacturing test jigs
  • CMO selection process and support for procurement, pilot build and early supply chain issue resolution

Results: deliverables and outcomes

The TMINI robotic system gained 510(k) clearance from the FDA in April 2023. TMINI system is an exciting step forward in robotics, offering a small footprint, open implant platform and intuitive workflow.
