Embodiment Construction

[0014] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0015] Such as figure 1 As shown, a kind of novel medical rivet of the embodiment of the present invention comprises: rivet 1, pressing sheet 2, locking screw 3 and suture 4 with needle. The rivet 1 is in the shape of a cone with a pointed head and a thick tail, which is beneficial for it to penetrate into the bone. The outer surface of the rivet 1 is threaded, which can increase the holding force on the bone after penetration and prevent the rivet 1 from withdrawing. The proximal end of the pressing piece 2 is set at the tail of the rivet 1, and the distal end of the pressing piece 2 has a first screw hole 5. The pressing piece 2 has various shapes, which are designed ...

Abstract

The invention discloses a novel medical rivet. The novel medical rivet comprises a rivet body, a pressing piece, a locking screw and a suture with a needle. The near end of the pressing piece is arranged on the tail of the rivet body, and a first screw hole is formed in the far end of the pressing piece. The rivet body is provided with a second screw hole. The locking screw penetrates into the first screw hole and the second screw hole and forms a stable tripod structure with the rivet body and the pressing piece. The suture is connected to the pressing piece and used for stitching reinforcement of a ligament attached to an avulsed bone block. The novel medical rivet can fix the avulsed bone block of a ligament or tendon around a joint in a pressurized mode, bone fracture healing is promoted, the ligament or tendon is repaired and reinforced, early functional training of postoperative affected limbs is promoted accordingly, and limb post-traumatic functions are improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel medical rivet. Background technique [0002] Tendon insertion injury is a common clinical orthopedic disease, and tendon insertion avulsion often requires surgical reconstruction. Currently, threaded rivets, a commonly used repair material in clinical practice, can effectively reconstruct such injuries. However, for the type of injury with avulsion bone fragments, there is a lack of strong fixation of the bone fragments, which will prolong the immobilization time of the affected limb after surgery, which is not conducive to the functional recovery and prognosis of patients. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of medical rivet to solve the clinical problems of poor fixation and repair of bone, joint, ligament and tendon avulsion fracture, unsatisfactory functional recovery af...
