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 clavicle intramedullary needle with a terminal extramedullary locking function 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 clavicular intramedullary nail with a terminal extramedullary locking function. Background technique [0002] Midshaft clavicle fracture is a common fracture type, and its surgical internal fixation methods include intramedullary fixation and extramedullary fixation. [0003] Extramedullary fixation is represented by steel plate, which has the advantage of good fracture fixation stability, and the disadvantage of more stripping around the clavicle and great blood supply damage. In addition, the fixation is too strong, resulting in stress shielding. These factors all affect fracture healing and are prone to bone fractures. Nonunion or delayed union, prone to re-fracture when internal fixation is taken. [0004] Intramedullary fixation methods include elastic intramedullary nails and ordinary Kirschner wires, which have the advantages of less stripping of soft tissue aro...
