Abstract

The invention relates to the technical field of medical instruments, in particular to a proximal tibia auxiliary osteotomy device. The device comprises a fine adjustment assembly mounted at one end, away from an ankle holding device, of a vertical line rod, the fine adjustment assembly comprises a mounting column fixedly connected to one end of the vertical line rod, an adjusting button rotationally arranged on the mounting column and a square fine adjustment rod arranged on the mounting column, the mounting column and the adjusting button are both coaxially arranged with the vertical line rod, a mounting groove is formed in the mounting column, the adjusting button is rotationally arranged in the mounting groove, a limiting groove which communicates with the mounting groove is formed in one end, away from the vertical line rod, of the mounting column, the fine adjustment rod is matched in the limiting groove in a sliding mode, a screw fixedly connected with one end of the fine adjustment rod is arranged inside the mounting column, and the screw penetrates through a rotary knob and is in threaded fit with the rotary knob. The device has the effects that the tibia osteotomy amount is improved by adjusting the fine adjustment assembly and a tibia fixing plate, and the problem that a retroversion angle of an osteotomy module cannot be adjusted is solved.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an auxiliary osteotomy device for the proximal end of the tibia. Background technique [0002] At present, for patients with early knee joint disease, unicompartmental joint replacement surgery is a widely used and effective treatment method. Unicompartmental joint replacement surgery has the advantages of less trauma, faster recovery, bone preservation, and good joint stability. , without destroying the original proprioception and soft tissue balance system of the patient's knee joint, the motion function of the patient's knee joint is preserved to the greatest extent, and the patient's satisfaction with the quality of rehabilitation is improved. The accuracy required for unicompartmental arthroplasty is relatively high. Clinical studies have confirmed that the accuracy of the prosthesis installation position directly affects the survival rate of the prosthesis...
