Abstract

The invention discloses a knee joint replacement balancer combining osteotomy measurement and a gap balance technology. The knee joint replacement balancer comprises an osteotomy amount and four-in-one osteotomy module setting instrument, which is characterized in that the osteotomy amount and four-in-one osteotomy module setting instrument comprises a handle, a setting platform, an osteotomy amount measuring structure and a four-in-one osteotomy module setting structure; the handle is connected with the setting platform, the four-in-one osteotomy module setting structure perpendicular to theupper plane of the setting platform is arranged on the setting platform, and the length of the setting platform is larger than the width of the four-in-one osteotomy module setting structure; the four-in-one osteotomy module setting structure comprises a part with a notch, and an osteotomy amount measurement structure with a right-angle bend is arranged in the notch; the osteotomy amount measurement structure comprises a vertical section and a horizontal section; the vertical section of the osteotomy amount measurement structure is arranged in the notch, and the horizontal section is used forextending out to find the thighbone edge so as to measure the osteotomy amount through the vertical section; and the four-in-one osteotomy module setting structure comprises a flat plate structure with different four-in-one osteotomy module insertion holes.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical devices, and in particular relates to a balance device used in total knee replacement surgery, in particular to a knee replacement balancer which combines osteotomy measurement and gap balance technology. Background technique [0002] Artificial total knee arthroplasty is a new technology for treating knee joint diseases that has gradually developed in modern times. It can effectively eradicate the pain of advanced knee joint diseases and greatly improve the quality of life of patients. [0003] However, total knee arthroplasty is a technically challenging procedure that requires osteotomy measurements and soft-tissue balancing of the patient in flexion and extension to obtain equal flexion-extension gaps and good patellar tracking. Especially for the measurement of the balance gap and the amount of osteotomy in the patient's flexed position, determining the angle of rotation and alignm...
