Problems solved by technology

However, mechanical locking sights are generally complicated to install and prone to deformation, resulting in changes in the positional relationship between the sight and the intramedullary nail. Return to the freehand aiming lock under the C-arm
Moreover, the sights of different manufacturers can only lock the intramedullary nails of their own manufacturers, which is not universal.
The computer navigation system under optical positioning requires large-scale computer image processing hardware, software and special surgical instruments, and requires the guidance of engineering and technical personnel, which limits the subjective initiative of doctors, and is expensive and difficult to promote

Abstract

A robot aided surgical system for the bone setting operation with the locking intramedullary nail is composed of multifunctional automatic operation bed, robot, bone setting regulator on said robot, bone fixing mechanism, high-accuracy full-automatic X-ray machine with C-shaped arm, navigation robot, robot controller, master hand control station, and slave hand control station.

Description

technical field [0001] The invention relates to a robot-assisted medical system for bone-setting surgery with a locking intramedullary nail. Background technique [0002] Traditional interlocking intramedullary nail bone setting surgery is divided into femur, tibia, etc. according to the different positions of the operation, and the difficulty of the operation is also different. Taking femoral bone setting surgery as an example, the basic process is as follows: firstly, the upper body of the patient should be fixed on the operating table, and two doctors will stretch the upper and lower parts of the patient's fractured femur outward, which is called traction. A doctor then immobilizes the patient's fracture laterally to keep it in a fixed position, called reduction. After the traction and reduction are completed, the attending doctor first makes a hole at the end of the condyle at one end of the femur to implant an intramedullary nail with a length similar to the length of ...
