Medical instrument tibia bone fracture plate for orthopedic surgery

Abstract

The invention discloses a medical instrument tibia bone fracture plate for an orthopedic surgery. The medical instrument tibia bone fracture plate comprises a bone fracture plate body, front face endmain fixing holes are fixedly formed in the two ends of the front face of the bone fracture plate body in a penetrating mode, front face end auxiliary fixing holes are formed in the positions, locatedon the two sides of the front face end main fixing holes, of the two ends of the front face of the bone fracture plate body in a penetrating mode, front face middle main fixing holes are symmetrically formed in the middle of the front face of the bone fracture plate body in a penetrating mode, front face middle auxiliary fixing holes are symmetrically formed in the positions, on the two sides ofthe front face middle main fixing holes, of the middle of the front face of the bone fracture plate body in a penetrating mode, side face end main fixing holes are formed in the two ends of the side face of the bone fracture plate body in a penetrating mode, and side face middle main fixing holes are symmetrically formed in the middle of the side face of the bone fracture plate body in a penetrating mode. The medical instrument tibia bone fracture plate has the advantages that the structure is simple and reasonable, the design is novel, and the higher tibia fixing firmness is realized in the tibia bone fracture aspect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tibial bone plate, a medical instrument for orthopedic surgery. Background technique [0002] The tibia is one of the two bones of the lower leg and is located on the inner side of the lower leg. It plays an important role in supporting body weight and is the main load-bearing bone in the lower leg. It can be divided into one body and two ends. The upper end is usually called the proximal end, and the lower end is usually called the distal end. The distal end fracture is a multiple fracture, and the fracture of the backbone between the two ends is a tibial body fracture. Happens less often, but still happens. [0003] Tibial fractures are a type of multiple fractures, accounting for about 1 / 4 of all fractures in the whole body. At present, the internal fixation materials used clinically are mainly titanium alloy materials. This material has the advantages of excel...

AI Technical Summary

Problems solved by technology

At present, the internal fixation materials used clinically are mainly titanium alloy materials. This material has the advantages of excellent corrosion resistance and mechanical properties, but its biocompatibility is poor, the price is expensive, and its density and elasticity are quite different from natural bone. , easy to cause stress shielding phenomenon, affect the growth of bone tissue and prolong the healing time

Moreover, the patient is prone to fracture of the bone plate due to the action of external force during the treatment, thus failing

[0004] In the prior art, the bone plate for the tibia generally only has screw holes with a fixed diameter and angle. For different fracture sites, using the same pattern of screws for fixation often affects the firmness of the bone plate fixation, and poor fixation may lead to The emergence of iatrogenic fractures is not conducive to the healing of patients' fractures
