Osteotomy guide plate and osteotomy system

Abstract

The invention provides an osteotomy guide plate and an osteotomy system. The osteotomy guide plate comprises a guide plate main body, a sliding groove, a siding block and a control device, wherein the guide plate main body is provided with a saw blade groove for osteotomy; the sliding groove is formed in the front surface and the rear surface of the guide plate main body in a penetrating mode, and a plurality of first arc grooves are formed in the inner wall of the sliding groove; the sliding block is arranged in the sliding groove in a sliding mode, a plurality of second arc grooves are formed in the sliding block, and each second arc groove can be correspondingly spliced with one first arc groove to form a round hole; and the control device is connected with the sliding block and can drive the sliding block to move in the sliding groove in a reciprocating mode so that channels between the adjacent round holes can be closed or opened. The osteotomy system comprises the osteotomy guide plate. According to the osteotomy guide plate, the position of the osteotomy guide plate can be rapidly adjusted under the condition that the osteotomy guide plate does not need to be taken down from a positioning needle and then fixed, the steps of taking down and fixing the osteotomy guide plate again are simplified, and the operation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, in particular to an osteotomy guide plate and an osteotomy system. Background technique [0002] In knee joint surgery, the articular surface needs to be properly osteotomized to meet the matching requirements of specific prostheses. The traditional osteotomy guide plate has positioning holes on the surface, and positioning needles are inserted into the positioning holes to roughly position the bone surface. If the positioning is found to be unsatisfactory, It is necessary to remove the osteotomy guide plate and readjust the cooperation between the positioning pin and the positioning hole to find the ideal osteotomy surface. This positioning method is time-consuming and laborious, which is not conducive to shortening the operation time. [0003] Therefore, there is an urgent need for an osteotomy guide plate and an osteotomy system to solve the time-consuming and laborious problem of...
