Abstract

An ulna thread-type protection steel plate comprises a straight steel plate, wherein a plurality of positioning holes are formed in the straight steel plate. The ulna thread-type protection steel plate further comprises a plurality of protecting wings which are symmetrically arranged on the two sides of the straight steel plate and face towards the inner side of the straight steel plates in a covering mode, wherein thread-type fixing holes or needle threading holes are formed in the protecting wings, countersink screws for rotationally connecting the ulna through threads are arranged in the thread-type fixing holes, the positioning holes are thread-type fixing holes and / or locking and pressurizing holes, countersink screws for rotationally connecting the ulna through threads are arranged in the thread-type fixing holes, and countersink pressurizing screws for rotationally connecting the ulna through threads are arranged in the locking and pressurizing holes.

Description

technical field [0001] The invention relates to the field of implant instruments, in particular to an ulnar threaded protective steel plate. Background technique [0002] In modern orthopedic surgery, most ulnar fractures are fixed by plate implantation. The traditional locking plate is provided with locking holes and locking pressure combination holes on the steel plate. The locking plate is locked on the dorsal side of the ulnar shaft with locking screws and compression screws. The locking plate is in the The fixation on the ulna is stable, but it only has a good fixation effect on the broken bone on the dorsal side of the ulna, and it cannot fix the broken bone on both sides of the ulna. Contents of the invention [0003] Aiming at the deficiency in the prior art that the bone fragments of the ulna cannot be fixed in an all-round way, the present invention provides a ulnar threaded protective steel plate capable of fixing the fragments of the ulna on both sides of the u...
