Problems solved by technology

In the usual operation, the ulna is manually sawed off by experienced doctors. Not only is it difficult to control the length of the osteotomy, but it is also easy to cause undulations on the saw surface; at the same time, the sawed ulna is easy to rotate and shift, which is not conducive to the subsequent precise docking and affects the operation. after healing
[0003] Ulnar lesions are very common in clinical work, and ulnar osteotomy and shortening are required in most cases. However, there is no reliable product on the market that can accurately control the thickness and angle of osteotomy, and at the same time shorten the time of shortening. Ability to control stump rotation for best clinical results

Abstract

The invention discloses a distal ulna osteotomy guider, which belongs to the technical field of medical instruments, and adopts the technical scheme that the distal ulna osteotomy guider comprises a fixing plate along the length direction of the ulna, and an osteotomy adjusting component arranged on the fixing plate, the osteotomy adjusting assembly comprises an anti-rotation plate and a scale plate which are sequentially arranged in the length direction of the fixing plate, the anti-rotation plate and the scale plate are both adjustably arranged on the fixing plate in the length direction, the osteotomy adjusting assembly further comprises a guide plate arranged on the scale plate, and the guide plate is adjustably arranged in the length direction of the scale plate; the distal ulna osteotomy guider provided by the invention has the functions of reasonable layout, simple structure, high osteotomy precision and flat osteotomy section, can enable the cut bones to be in accurate butt joint, solves the problem that the sawed ulna is easy to rotate and shift, and is beneficial to postoperative bone healing.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a distal ulna osteotomy guide. Background technique [0002] Ulnar impingement syndrome caused by a positive variant of the ulna is a common cause of ulnar wrist pain. Because the impingement of the ulnar carpal bone and the ulnar head causes wrist pain and functional limitation, ulnar shortening osteotomy is required. The usual operation is to manually saw the ulna by an experienced doctor, which is not only difficult to control the length of the osteotomy, but also easily causes the sawing surface to be uneven; at the same time, the sawed ulna is easy to rotate and shift, which is not conducive to the subsequent precise docking and affects the operation. after healing. [0003] Ulna lesions are very common in clinical work, and ulna osteotomy is required in most cases, but there is currently no reliable product on the market that can accurately control the thickness an...
