Needle-type locking osteosynthesis plate nail system structure for radius distal fracture

Abstract

A needle-type locking osteosynthesis plate nail system structure for radius distal fracture includes an implantation needle, a compression fixing needle, a bent part, a compression plate, locking screws and a cortical bone screw; the implantation needle is connected with the compression fixing needle through the bent part; a compression part has a ''U'' structure, and the tail end of the compression part is in the shape of an arc; the compression plate is arranged on both arms of the compression part, and the compression plate is provided with an inverted cone-shaped fixing groove to simultaneously press both arms of the compression part; and screw holes are arranged in the compression plate, and the locking screws and the cortical bone screw pass through the screw holes to pressurize andfix a bone block. The needle-type locking osteosynthesis plate nail system structure reduces ligament peeling during surgery, has smaller damage to a patient, reduces the pain of the patient, and cangreatly shorten the recovery period of the patient; and the needle-type locking osteosynthesis plate nail system structure also reduces the difficulty of bone reduction, improves the success rate of the surgery, and is more convenient for clinical operation.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a needle-type locking plate and nail system structure for distal radius fractures. Background technique [0002] Fracture is one of the most common injuries. With the aging of the population, the annual incidence of fractures is gradually increasing. Surgery is a more effective treatment option. With the continuous introduction of new surgical theories, people realize that the soft tissue around the fracture The degree of injury and ensuring a good blood supply to the bone tissue are equally important, and the structure of the needle-type locking plate and screw system is a good solution to reduce irritation to the soft tissue. [0003] The headless pressurized hollow screw in the prior art includes a screw head, a screw shank, a screw tail and a screw core hole. A uniform continuous thread is arranged on the outside of the screw, and a nail tip is set on the s...

Problems solved by technology

[0003] The headless pressurized hollow screw in the prior art includes a screw head, a screw shank, a screw tail and a screw core hole. A uniform continuous thread is arranged on the outside of the screw, and a nail tip is set on the screw head. The hole tool drills holes in the bone tissue, and then the screw is screwed in with the guidance of the nail tip, but the headless pressure hollow screw of the prior art cannot effectively pressurize, and it is easy to irritate the soft tissue around the bone, making it difficult to screw in the screw. , and there is a risk of bone burst caused by screw tail screwing in diameter becomes larger
