Abstract

The invention discloses an integrated fixing device for an olecranal fracture. The integrated fixing device comprises a banded knitted part and a rope bolt, wherein one end of the banded knitted part is connected with the tail end of the rope bolt; the other end of the banded knitted part is connected with a traction needle; the rope bolt is arranged in an olecranal fracture part for connection; and the banded knitted part is pressed on the olecranal fracture part and is tightened and fixed. The integrated fixing device has excellent biocompatibility; stimulation of implants to the implanted part is avoided; the difficulty that the implants need to be taken out by a secondary operation is avoided; the banded knitted part has relatively low elasticity modulus; blood supply of the fixed part is effectively protected when efficient fixation is provided; the postoperative pain of a patient is reduced; the recovery cycle of the patient is shortened; the banded knitted part provides an effective fixing mode for the slight comminuted olecranal fracture; and in addition, 'minimally invasive idea' is introduced, so that the problems that a previous surgery is complicated in operation, large in wound, serious in post operational pain and local stimulation and the like are solved.

Description

technical field

[0001] The invention relates to the technical field of medical device design, in particular to an integrated fixation device for olecranon fractures. Background technique

[0002] The subcutaneous protrusion behind the proximal end of the ulna is called the olecranon, which forms a semilunar notch with the coronoid process of the front ulna. This notch just forms the ulnar-humeral joint with the trochlea of ​​the humerus, and the ulnar-humeral joint can only flex and extend. Olecranon fractures refer to intra-articular fractures involving the semilunar notch. Olecranon fractures are intra-articular fractures that are often associated with fractures and soft tissue injuries in other parts. Fracture reduction requires high requirements, and early functional training is required after surgery.

[0003] At present, the commonly used surgical method for the treatment of such fractures is Kirschner wire tension band fixation. The principle of this operation method...
