Abstract

The invention discloses an ulna intramedullary nail which comprises a first nail body and a second nail body which are coaxially connected. The diameter of the first nail body is larger than that of the second nail body. Three parallel fixing holes are formed in the first nail body and perpendicular to the axial direction of the first nail body. An external thread surface is formed at the portion, close to the tail end, of the second nail body. The ulna intramedullary nail is simple in structure, high in safety, suitable for meeting clinical requirements and high in tensile strength, and since the ulna intramedullary nail is implanted in a medullary space to be fixed, the aims of being small in wounds and stable in fixation can be achieved; in addition, a far end thread is screwed in the medullary space, and a near end conducts pressurizing through equipment, so a bone can be more rapidly cured.

Description

technical field [0001] The present application relates to an orthopedic medical device, in particular to an ulna intramedullary nail. Background technique [0002] Usual proximal ulna fractures with surgical techniques for restoration of the injured site. [0003] Ulnar intramedullary nailing is osteosynthesis, and it is also a new technology of modern fracture fixation. It uses indirect fracture reduction technology and fixes with intramedullary implants to maintain fracture alignment, which minimizes surgical exposure and soft tissue stripping, and can Improve fracture healing rate. [0004] Traditional ulnar intramedullary nails have technical problems of complex structure, low safety performance, low tensile strength, and unstable fixation. Contents of the invention [0005] The object of the present invention is to provide an ulnar intramedullary nail to overcome the deficiencies in the prior art. [0006] To achieve the above object, the present invention provides...
