Clamping instrument of pelvic fracture reduction robot

Abstract

The invention relates to a clamping instrument of a pelvic fracture reduction robot. The clamping instrument is composed of an affected side main frame module, an affected side secondary frame module, an affected side lower frame module, a butt joint module, a bone needle clamping device and an uninjured side fixing frame module, wherein the affected side main frame module is used for fixing a bone needle of a pelvic anterior superior spine, the affected side secondary frame module is used for fixing a bone needle of a pelvic anterior inferior spine, and the affected side lower frame module is used for fixing a bone needle of a pelvic ilium; the butt joint module is used for rapidly connecting the clamping instrument with a surgical robot, the tool end module is connected with the affected side main frame module, and the robot end module is connected with the robot; the uninjured side fixing frame module is used for fixing bone needles placed into the pelvis on the uninjured side; the bone needle clamping device is used for clamping bone needles and has the advantages of being flexible in adjustment and tight in clamping. The clamping instrument has the remarkable advantages of being compact in structure, flexible to adjust, large in rigidity, firm to fix, easy to assemble and disassemble and the like, and can adapt to different space poses of bone needles according to the injury types of the pelvis of a patient to achieve stable clamping.

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to a clamping instrument for a pelvic fracture reduction robot. Background technique [0002] Pelvic fracture is a serious trauma, accounting for 1% to 3% of the total fractures, mostly caused by high-energy trauma, more than half of which are accompanied by complications or multiple injuries, and the disability rate is as high as 50% to 60%. In pelvic fracture surgery, it is usually necessary to fix multiple bone pins in different spatial orientations, and the reduction force is as high as 500N. [0003] Traditional pelvic fracture reduction surgery relies on the doctor's experience for the reduction effect, and has disadvantages such as low surgical accuracy, radiation exposure to both the doctor and the patient during the operation, many postoperative complications, and a high repair rate. With the rapid development of robotic technology, robots can replace traditional su...
