Medical hand and foot bone and patellar fracture malformation correction external fixator

Abstract

The invention relates to a medical hand and foot patellar fracture malformation correction external fixator, in particular to external fixation instrument and equipment for treating hand and foot palmoplantar phalangeal and patellar fracture malformation correction. The external fixator is composed of cardan shafts, rotary sleeves, fixing plates, sliding grooves, locking bolts, fixing bolts, traction pins and fixing nuts. External fixators can be divided into parallel-bar fixators, parallel-bar fixators with threads, single-bar fixators, single-bar fixators with threads, straight connection single-bar fixators and straight connection single-bar fixators with threads. The external fixator has the advantages that the structure is simple, operation is convenient and flexible, multiple functions are combined, the structural forms are diversified, the angular position and the space between the fixing plates are flexible to adjust, the therapeutic effect is improved, pain of a patient is reduced, occlusion adjustment is achieved, a fracture is reset, a malformation is corrected, closed stretch of skins is achieved, the frequency of operations is decreased, the operation wound surface is reduced, recovery of the patients is facilitated, and the external fixator is widely applied to hand and foot bone or patellar fracture malformation correction.

Description

Technical field: [0001] The invention relates to a medical external fixator for deformity correction of patella fractures of hands and feet, in particular to an external fixation device used for correcting deformities of palmar, metatarsal, phalangeal and patella fractures of hands and feet. Background technique: [0002] At present, there is no treatment and separation device in the prior art, and the external fixation device for the treatment of palmar, metatarsophalangeal and patella fractures and deformity correction in the hands and feet is relatively large, and cannot meet the clinical treatment needs in terms of function. Patella fracture needs open reduction and internal fixation. After the fracture heals, the patient needs to be re-operated to remove the implant. The trauma area is large, and the incision scar is left on the skin in front of the patella. It is uncomfortable to be rubbed by underwear, and the skin of other parts of the body needs to be removed after t...

Problems solved by technology

[0002] At present, there is no treatment and separation device in the prior art, and the external fixation device for the treatment of palmar, metatarsophalangeal and patella fractures and deformity correction in the hands and feet is relatively large, and cannot meet the clinical treatment needs in terms of function. Patella fracture needs open reduction and internal fixation. After the fracture heals, the patient needs to be re-operated to remove the implant. The trauma area is large, and the incision scar is left on the skin in front of the patella. It is uncomfortable to be rubbed by underwear, and the skin of other parts of the body needs to be removed after the separation of fingers and toes. Skin grafting between the fingers increases the wound surface, and the skin grafting area of ​​the hand feels uncomfortable for life, causing great pain to the patient, bringing mental and economic burdens, and the treatment effect is not ideal
