Guide plate for bone transport of tibia osteotomy

Abstract

The invention discloses a guide plate for bone transport of tibia osteotomy. The guide plate comprises a fixing plate and an expansion plate, wherein the expansion plate is detachably connected with the fixing plate, the expansion plate is provided with expanded drill holes, the fixing plate is a horizontal long strip plate, drill holes are uniformly distributed in the fixing plate, a plurality ofthreaded through holes running through the fixing plate from the upper surface to the lower surface are formed in the fixing plate, the threaded through holes are formed along the axis of the long axis of the fixing plate, the threaded through holes are internally in threaded connection with handles, each handle comprises a hand-held part and a connecting part, the connecting parts are in threaded connection with the threaded through holes, the hand-held parts are exposed outside the threaded through holes, the handles are hollow sleeves, the sleeves are internally provided with internal threads, and the sleeves are internally in threaded connection with fixing screws. The tibia surfaces fit the fixing plate, the tibia is fixed through the fixing screws, holes are drilled in the tibia insequence from the drill holes by using a drill bit, then the drill holes are communicated by using an osteotome, and a square bone can be taken down, thereby ensuring the uniformity and accuracy of drilling.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a guide plate for bone-transporting tibial osteotomy. Background technique [0002] In the bone-handling tibial osteotomy, a square bone needs to be cut off from the patient's tibia, but at present, when performing this operation, there is a lack of corresponding devices for fixing the tibia, so when drilling the osteotomy, doctors often rely on their experience Operational drilling is performed, which often results in unevenness and accuracy of drilling on the tibia. [0003] Therefore, how to solve the above problems has become the focus of research by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a guide plate for bone-transporting tibial osteotomy, which can completely solve the shortcomings of the above-mentioned prior art. [0005] The purpose of the present invention is achieved throu...
