Technical Field

The invention relates to the technical field of medical instruments, in particular to a minimally invasive combined radial tendon and bone fixing nail.

Background

At present, when fracture fixation such as humerus tubercle fracture, olecranal fracture, tendon and bone avulsion fracture at a near joint part, patella tendon and tibia tubercle fracture is clinically carried out on a patient, holes are traditionally drilled at the fracture edge part, steel plates are installed and fixed by steel nails, but the traditional method is long in steel plate fixation, large in wound during fixation, long in postoperative recovery time of the patient and painful in the recovery process.

Disclosure of Invention

The invention aims to provide a minimally invasive combined radial tendon bone fixing nail to solve the problems of long fixing steel plate and large wound during fixing in the background technology. In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a radial tendinous bone staple of wicresoft combination formula, includes the main nail, the main nail includes the main nail body and the head of a nail, the head of a nail central point puts and connects the main nail body, the head of a nail is equipped with round radiation nail fixed orifices along the circumference equidistance, the radiation nail fixed orifices internal connection installation radiation nail.

Preferably, the main nail body and the nail head are connected through threads or are of an integral structure, and the nail head is plate-shaped.

Preferably, the radiation nails and the main nail body are circumferentially distributed at 15-25 degrees.

Preferably, the number of the radiation nails is 3-5, and the conical screw threads are connected and fixed on the nail cap.

Preferably, the main nail body diameter is 4.5mm, the main nail body is hollow nail, and the latter half is equipped with the screw thread, the radiation nail diameter is 2.5 mm.

Preferably, a suture hole is arranged between the adjacent radiation nail fixing holes.

The invention has the technical effects and advantages that: the sleeve device is characterized in that the main nail cap is plate-shaped, the main nail body is positioned at the center of the nail cap, the wound is small during fixation, and minimally invasive treatment is realized. Each radiation nail is combined with the top cap of the main nail, so that the fracture block can be effectively fixed, and the anti-pulling and anti-withdrawal effect is good.
