Abstract

The invention discloses a tibia osteotomy positioning device for a knee joint replacement surgery. The tibia osteotomy positioning device comprises an osteotomy unit, a backward inclination angle adjuster and a first toe and second toe aligner, wherein an arc-shaped contact surface is arranged at the inner side of the osteotomy unit; an osteotomy groove penetrating through the osteotomy unit is arranged at the outer side of the osteotomy unit; a plurality of first positioning holes and a plurality of second positioning holes are respectively arranged at the upper end and the lower end of the osteotomy groove; the number of the first positioning holes is larger than the number of the second positioning holes; and fixators used for fixing the osteotomy unit to the outer surface of the tibiaare detachably arranged in the first positioning holes and the second positioning holes. When the fixators penetrates through the first positioning holes and the second positioning holes to fix the osteotomy unit on the tibia, a majority of the fixators are nailed into the bone of the spinous process of the tibia located above the osteotomy groove, while the bone of the spinous process of the tibia located above the osteotomy groove is cut off in a surgery, so the injury of the fixators to the tibia can be greatly reduced; postoperative pain is reduced; and the postoperative recovery effect ofa patient is improved.

Description

technical field [0001] The invention relates to the technical field of surgical aids, in particular to a tibial osteotomy positioning device for knee joint replacement surgery. Background technique [0002] During knee replacement surgery, it is necessary to use a knife to resect the bones of the distal femur and the proximal tibia, and when using a knife to resect the bones of the proximal tibia, a positioning device is usually required for positioning, so that the knife can pass through the positioning device. Precise osteotomy operation. When the existing positioning device is fixed on the tibia, four or more fixing screws need to be nailed into the inside of the tibia below the osteotomy groove for fixation, which will cause great damage to the patient's tibial bone itself and affect the postoperative recovery. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the...
