Bone block fixing device for proximal humerus comminuted fractures

Abstract

The invention relates to a bone block fixing device for proximal humerus comminuted fractures, belonging to the technical field of orthopaedic medical instruments, for fixing a plurality of bone blockss of proximal humeral comminuted fracture. The technical scheme is as follows: the lower end of the connecting rod of the intramedullary nail is threaded and matched with the screw hole of the tail of the intramedullary nail; the upper end of the connecting rod of the intramedullary nail is a rotating shaft; one end of the horizontal rotating piece is provided with a shaft hole and is rotatably connected with the rotating shaft of the upper end of the intramedullary nail connecting rod, and the other end of the horizontal rotating piece is bent and connected with the upper end of the aiming plate; the aiming plate is parallel to the nail body of the intramedullary nail, and the plate surface of the aiming plate is opposite to the intramedullary nail; the plate surface of the bone plate islocated between the nail body of the intramedullary nail and the plate surface of the aiming plate; the upper end of the bone plate is connected with a screw, and vertical screw holes are arranged onthe plate surface of the horizontal rotating plate; and the screw on the upper end of the bone plate is connected with the screw holes of the horizontal rotating plate. The bone block fixing device for proximal humerus comminuted fractures can fix a plurality of fracture bone fragments of the proximal end of the humeral fracture in multiple directions and angles, and achieves a satisfactory reduction effect.

Description

technical field [0001] The invention relates to a device for fixing multiple bone fragments of comminuted proximal humeral fracture, belonging to the technical field of orthopedic medical devices. Background technique [0002] Proximal humerus fracture is a common fracture in clinical practice, and its incidence rate shows a rising trend, which is one of the difficulties in the current trauma orthopedic treatment. The classification of proximal humeral fractures is of great significance, which can guide treatment, judge prognosis, and facilitate communication among colleagues. Currently, the most commonly used classification is the Neer classification. Proximal humeral fractures mainly include four parts: the humeral head, the greater tuberosity, the lesser tuberosity, and the humeral shaft. The degree of displacement between these four fragments determines the Neer classification of the fracture. The principle of treatment for proximal humeral fractures is to strive for i...

Problems solved by technology

This surgical plan can use minimally invasive techniques to reduce soft tissue damage, but it is difficult to reduce multiple bone fragments in comminuted fractures

[0006] At present, there is no better solution for comminuted fractures of the proximal humerus except open reduction and internal fixation with locking plates, and this traditional solution does not conform to the current development trend of minimally invasive surgery, so it is necessary to develop New technical solutions to improve surgical results, reduce patient pain, and provide technical support for the development of bone minimally invasive surgery
