Portable tibial fracture reduction robot

Abstract

The portable tibia fracture reduction robot comprises a movable bottom plate assembly, a three-degree-of-freedom moving platform is arranged on the bottom plate assembly, a two-degree-of-freedom rotating platform is arranged at one end of the three-degree-of-freedom moving platform, and a foot plate is arranged at one end of the two-degree-of-freedom rotating platform; the first fixing device is used for fixing the far end of the broken bone, the second fixing device is used for fixing the near end of the broken bone, the first fixing device is arranged at one end of the foot plate, and the second fixing device is arranged at one end of the operating table. According to the five-degree-of-freedom series robot, compared with a traditional six-degree-of-freedom series robot, the five-degree-of-freedom series robot has higher precision and higher response speed, operation is more convenient, meanwhile, the size is reduced, and portability is easy to achieve; in addition, the first fixing device and the second fixing device can complete angulation eliminating operation of the fracture part in the operation process, the operation precision is improved, and the fracture operation can be rapidly conducted conveniently.

Description

technical field [0001] The invention relates to the technical field of surgical medical instruments, in particular to a portable tibial fracture reduction robot. Background technique [0002] With the development of medical technology, more and more robots are used to assist doctors in surgical operations; among them, the core concept of fracture reduction robots is to replace manual reduction by the operator's remote operation of the reduction machine, so as to reduce the need for medical radiation exposure to patients and provide continuous, stable, quantitative and precise operation during repositioning. [0003] However, both the current series and parallel fracture reduction robots have certain defects; among them, the parallel fracture reduction robot has a relatively small workspace and complicated control, and needs to be implemented in combination with intramedullary nailing and internal fixation in clinical practice. , The clamping form and length of the proximal ...

AI Technical Summary

Problems solved by technology

[0003] However, the current serial and parallel fracture reduction robots have certain defects; among them, the parallel fracture reduction robot has a relatively small working space and complex control, and it needs to be implemented in combination with intramedullary nail internal fixation technology in clinical practice, which is far away from fractured bones. , The clamping form and length of the proximal end put forward requirements. When the muscle tension of the patient causes excessive muscle contraction tension, the clamping of the broken bone by the robot end effector will be affected, resulting in the posture of the robot in the process of fracture reduction. It may be uncontrollable; due to the large size of the serial fracture reduction robot, it will occupy a large surgical space, which limits the operating space of the medical staff. Decreased positioning accuracy
