Abstract

The invention discloses a clavicle intramedullary needle with a terminal extramedullary locking function, relates to the technical field of medical instruments, and can solve the problem of looseness and displacement of an intramedullary needle, avoid complications caused by looseness and displacement and improve the treatment effect and the postoperative recovery effect. The invention discloses an intramedullary locking needle with a terminal extramedullary locking function. The intramedullary locking needle comprises a needle body and a locking and fixing mechanism, the needle body is used for intramedullary fixation of a fractured clavicle. And the locking and fixing mechanism is sleeved on the needle body. The locking and fixing mechanism is used for fixing the needle body. The needle body can be inserted into a fractured clavicle marrow cavity to fix a fractured clavicle, and the locking and fixing mechanism can fix the needle body on a bone substance, so that the needle body is prevented from loosening and displacing, complications are avoided, and the treatment effect and the postoperative recovery effect are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a locked intramedullary needle with a terminal extramedullary locking function. Background technique [0002] Middle clavicle fracture is a common type of fracture, and its surgical internal fixation includes intramedullary fixation and extramedullary fixation. [0003] Extramedullary fixation is represented by steel plate, which has the advantages of good stability of fracture fixation, but the disadvantage is that there is a lot of peeling around the clavicle, and the blood supply is damaged. In addition, the fixation is too strong and produces stress shielding. Non-union or delayed union, prone to refracture when internal fixation is taken. [0004] Intramedullary fixation methods include elastic intramedullary needle and ordinary Kirschner wire fixation. The advantages are less peeling of soft tissue around the clavicle, less damage to blood supply, less tissue damag...
