简要总结

Developed a robot for minimally invasive TKA surgery and prepare for the subsequent CFDA application of the minimally invasive total knee replacement robot system.

详细描述

  1. For the current minimally invasive total knee arthroplasty, due to the limitation of the surgical field of view and the scope of operation, and the error of the intraoperative osteotomy saw, it can cause intraoperative damage to ligaments, nerves and blood vessels, postoperative lower limb force lines and prosthesis position Poor, abnormal movement and force of the patellofemoral joint and tibiofemoral joint after surgery can easily lead to clinical symptoms such as rapid wear of the prosthesis, short service life, postoperative knee pain, and even possible problems with surgical failure and revision. Developed a robot for minimally invasive total knee replacement surgery. Minimally invasive total knee arthroplasty is performed by surgical robot and manual operation. According to intraoperative and postoperative imaging observations, the position of the prosthesis, and the evaluation of soft tissue balance during and after the operation, the two methods are compared with the surgical robot and manual operation. Kind of surgery.
  2. To prepare for the subsequent CFDA application of the minimally invasive total knee replacement robot system.
