Embodiment Construction
[0020] The present invention will be further described below with reference to the embodiments and the accompanying drawings.
[0021] like figure 1 As shown, a clamping mechanism for robot-assisted lower extremity fracture reduction surgery is composed of a proximal fracture fixing mechanism module I, a distal fracture clamping mechanism module II, and a reduction force testing module III. The proximal fracture fixing module is composed of The bracket 1 of I is fixed on the frame of the operating bed through the first bolt 2, the proximal fracture fixing module I fixes the proximal fracture 12 through the first bone pin 11, and the connecting plate 14 of the distal fracture clamping module II is connected to the parallel reduction robot. The moving platform is connected by the third bolt 15, the fracture distal end clamping module II clamps the fracture distal end 13 through the second bone pin 22, and the distal muscle bundle fixing plate 26 of the reduction force test modul...

The invention relates to a clamping mechanism for a robot-assisted lower limb fracture reduction operation. The clamping mechanism is composed of a fracture near-end fixing module, a fracture far-endclamping module and a reduction force testing module. The fracture near-end fixing module is installed on an operating bed. The fracture near-end fixing module is used for fixing a fracture near end through a bone needle; the fracture far-end clamping module is connected with a movable platform of a parallel reduction robot; the fracture far-end clamping module clamps the fracture far end throughthe bone needle, a far-end muscle bundle fixing plate of the reduction force testing module is installed on an arc support of the fracture far-end clamping module, and a force sensor installation baseof the reduction force testing module is fixed to a support of the fracture near-end fixing module. The clamping mechanism can achieve the fixing of the fracture near end of the lower limb of a patient, the clamping of the fracture far end and the precise reduction operation, can test the change rule between the reduction force and the driving force of a linear electric cylinder in the fracture reduction process, and can be used for the external force estimation and collision detection in the parallel reduction robot operation reduction process.
Description
technical field [0001] The invention belongs to the technical field of robots, and relates to a clamping mechanism used for robot-assisted lower limb fracture reduction surgery. Background technique [0002] With the development of medical technology, people's requirements for the safety of fracture reduction surgery and the convenience of surgical operations are gradually increasing. Robot-assisted fracture reduction surgery gradually replaces the traditional manual reduction by surgeons. At present, lower limb fracture reduction robots mainly use parallel reduction robots. The fracture fixation mechanism of the existing parallel reduction robot has a fixation blind spot near the femoral head, which is inconvenient to operate and the fracture fixation is not firm during the fracture fixation process. These problems directly affect the safety and accuracy of fracture reduction surgery. [0003] On the other hand, in order to improve the safety of the operation, people introd...
