Ulna far-end inner side bone fracture plate

Abstract

The invention discloses an ulna far-end inner side bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body is divided into a near-wrist joint part, a middle section and a far-wrist joint part, and the near-wrist joint part is provided with a near-wrist kirschner wire hole, a near-wrist locking hole, a near-wrist lower kirschner wire hole and a near-wrist lower locking hole from top to bottom. The middle section is provided with multiple middle kirschner wire holes and multiple middle locking holes from top to bottom, the multiple middle kirschner wire holes and the multiple middle locking holes are distributed in the middle section in an up-down staggered mode, the lower portion of the near-wrist lower locking hole is adjacent to the middle kirschner wire holes, and the lower portion of the near-wrist lower locking hole is adjacent to the middle locking holes. The far wrist joint part is provided with a far wrist sliding hole, a far wrist locking hole and a far wrist kirschner wire hole from top to bottom. The width and the curvature of the bone fracture plate are designed according to the anatomical structure of the inner side of the far end of the ulna, and the bone fracture plate is an anatomical locking plate and can be tightly attached to the bone cortex without intraoperative shaping, so that the strength of the bone fracture plate cannot be reduced, and the operation time cannot be prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a distal ulna medial bone plate. Background technique [0002] Distal ulna fractures are one of the common fracture types, and distal ulna fractures include ulnar styloid fractures. When the fracture of the ulnar styloid process is serious, internal fixation with a bone plate is required. However, the existing distal ulna bone plate has many disadvantages in the treatment of ulnar styloid process fractures, for example: there is no Kirschner wire hole in the distal end of the bone plate, which makes it impossible to perform temporary positioning, temporary fixation, and suture small bone pieces or ligaments, etc., resulting in The bone plate is easy to shift during fixation, and the position of the bone plate and the fracture end needs to be adjusted many times during the operation. The operation takes a long time and the fixation effect is poor. Point-type reduction fo...

However, the existing distal ulna bone plate has many disadvantages in the treatment of ulnar styloid process fractures, for example: there is no Kirschner wire hole in the distal end of the bone plate, which makes it impossible to perform temporary positioning, temporary fixation, and suture small bone blocks or ligaments, etc., resulting in The bone plate is easy to shift during fixation, and the position of the bone plate and the fracture end needs to be adjusted many times during the operation. The operation takes a long time and the fixation effect is poor. Point-type reduction forceps clamp the fracture end for temporary fixation and reduction; there is no Kirschner wire hole at the proximal end of the bone plate, and it is impossible to temporarily fix and locate whether the proximal end of the bone plate is in the middle of the ulna; the bone plate does not have a separate sliding hole, so it cannot be Micro-adjustment of the fracture end by micro-sliding cannot make the bone fit the bone plate better
