Abstract

The invention provides an adjustable gasket for osteotomy. The gasket includes an upper gasket, a lower gasket and an adjusting assembly; the adjusting assembly is arranged between the upper gasket and the lower gasket, connected with the upper gasket and the lower gasket, and used for adjusting the spacing and angle between the upper gasket and the lower gasket to a preset spacing and a preset angle to make the upper gasket and the lower gasket abut against a first osteotomy surface and second osteotomy surface of an osteotomy area when the adjustable gasket for the osteotomy is implanted into the osteotomy area of the tibia respectively. Thus, the thickness and tilt angle of the gasket can be freely adjusted according to the conditions of different patients during the high tibial osteotomy to adapt to different osteotomy needs. The problem is solved that the thickness and cleaning angles of gaskets adopted in the existing high tibial osteotomy cannot be adjusted.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an osteotomy adjustable spacer. Background technique [0002] Knee osteoarthritis is a common senile degenerative disease based on uneven subsidence of the knee joint caused by osteoporosis. The main clinical manifestations include joint pain, deformity, stiffness, and dysfunction. According to the affected parts and scope of knee osteoarthritis, it can be divided into medial compartment type, lateral compartment type, patellofemoral type and total joint type. Among them, medial compartment type accounts for the majority of primary osteoarthritis. 74%. Patients with medial compartment knee osteoarthritis are often accompanied by changes in the alignment of the lower limbs and varus deformity, which seriously affect the quality of life. [0003] The commonly used clinical method is to use high tibial osteotomy to treat knee osteoarthritis. The mechanism is mainly through high we...
