Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] combine figure 1 As shown, the humeral inverted intramedullary nail includes a first rod body 1 located at the distal end and a second rod body 2 located at the proximal end. The first rod body 1 and the second rod body 2 are coaxially connected into one body. The diameter is larger than the first rod body 1, and the second rod body 2 is provided with 4 first round holes 21 and 1 second round hole 22, and the 4 first round holes 21 are respectively perpe...

Abstract

The present application discloses an inverted humerus intramedullary nail, which includes a first rod body located at the distal end and a second rod body located at the proximal end, the first rod body and the second rod body are coaxially connected into one body, and the second rod body The outer diameter of the first rod body is larger than that of the first rod body, and four first round holes and one second round hole are opened on the second rod body, and the four first round holes are respectively perpendicular to the axis of the second rod body direction, and the four first round holes form a certain angle with each other, and the angle between the second round hole and the axial direction of the second rod body is 45°, and the first rod body is provided with two The third circular hole, the two third circular holes are perpendicular to the axial direction of the first rod body, and a certain angle is formed between the two third circular holes. The inverted humeral intramedullary nail provided by the new model has simple structure and high safety, and is suitable for clinical needs. The intramedullary nail has high tensile strength, can be used for femoral shaft fractures, and can achieve the purpose of small surgical incision and fast and convenient surgery.

Description

technical field [0001] The present application relates to an orthopedic medical device, in particular to an inverted humerus intramedullary nail. Background technique [0002] It is usually used for proximal humeral fractures, and the injured part is restored by surgical techniques. [0003] Inverted humerus intramedullary nailing is osteosynthesis, which 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. Can improve fracture healing rate. [0004] Inverted humerus intramedullary nail, its biggest advantage is that the incision at the nail entry point is small, the proximal end is locked and fixed, the operation risk is small, the blood supply is not affected, the healing is fast, and the incidence of complications is reduced. [0005] Traditional humeral inverted intramedullary nails have tech...
