Double-column locking plate for distal radius palmaris

Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a double-column locking plate for distal radius palmaris. The double-column locking plate comprises a straight plate body which is provided with a shield-shaped head, four locking compression holes and a compression locking hole, the compression locking hole is positioned in the upper middle of the straight plate body, two furcated column head bodies are formed at the upper end of the straight plate body, and each column head body is provided with a plurality of screw holes. The double-column locking plate for the distal radius palmaris has the advantages that the straight plate body is provided with the shield-shaped head, the four locking compression holes and the compression locking hole, the compression locking hole is positioned in the upper middle of the straight plate body, the two furcated column head bodies are formed at the upper end of the straight plate body, each column head body is provided with the screw holes, and accordingly damage to soft tissues during implantation can be reduced; by the aid of the screw holes, multiple kinds of selection is facilitated, more selection can be achieved and locking is firm.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a double-column locking plate at the palm side of the distal radius. Background technique [0002] During surgery, when encountering fractures or fractures, etc., it is necessary to use a locking plate made of metal corresponding to the corresponding part to lock the damaged part of the bone. Usually, special screws are used, or corresponding locking plates are used. The special locking screw in the hole is implanted in the body for locking. [0003] At present, when performing bone locking of the distal radius, especially when locking the volar side of the distal radius, the locking plate used has an unreasonable design of the locking hole and an unscientific plate structure, resulting in unstable locking. After locking, the screw holds the The strength is not strong, and it is easy to be pulled out after a long time, causing the lock to fail and lose the lo...

Problems solved by technology

[0003] At present, when performing bone locking of the distal radius, especially when locking the volar side of the distal radius, the locking plate used has an unreasonable design of the locking hole and an unscientific plate structure, resulting in unstable locking. After locking, the screw holds the The strength is not strong, and it is easy to be pulled out after a long time, causing the lock to fail and lose the locking function, which is not conducive to the recovery of the patient's body. In addition, it is easy to cause secondary injuries to the patient during implantation, which increases the pain of the patient.
