Fracture external fixation stereoscopic shaping brace

Abstract

The invention discloses a fracture external fixation stereoscopic shaping brace, and belongs to the technical field of orthopedic medical apparatus and instruments. The fracture external fixation stereoscopic shaping brace is used for fixating fracture from the outside of a limb. The technical scheme includes that a shaping soft titanium steel plate comprises a top plate and two side plate, the two side plates are connected to two sides of the top plate and are oblique towards the outer sides of the top plate, locking screw holes are formed in plate surfaces of the top plate and the side plates, the front ends of locking screws are connected with the upper surface and the side surfaces of a fracture broken end, nuts of the locking screws are connected with the plate surfaces of the top plate and the side plates, the lower ends of the two side plates are connected with each other by draw bars, the bending radians of the draw bars are matched with the curvature of the lower portion of the limb of a fracture site, and a silicone pad is positioned on the bottom surface of the shaping soft titanium steel plate. The fracture external fixation stereoscopic shaping brace has the advantagesthat the fracture broken end can be stereoscopically stably fixated without joint fixation, and dislocation and shaking of the fracture site can be prevented; joint stiffness due to joint fixation infracture healing procedures can be prevented, and novel ways can be developed for external fixation for fracture near joints.

Description

technical field [0001] The invention relates to an appliance for fixing fractures outside a limb, and belongs to the technical field of orthopedic medical instruments. Background technique [0002] In the treatment of various fractures caused by trauma, it is often necessary to perform external fixation with plaster after manual reduction, or to adopt surgical methods for fixation, and most patients use non-surgical external fixation. At present, before the patient's fracture is fully healed, the firm fixation of the fracture site is still a difficult problem in the treatment process. On the one hand, when plaster external fixation is used, it is often necessary to fix the fracture of the diaphysis near the joint. For example, the wrist joint needs to be fixed for the distal radius fracture, which will easily cause joint stiffness after the fracture is cured; on the other hand, the material of plaster external fixation is relatively low. Thick and airtight, the patient's li...

Problems solved by technology

On the one hand, when plaster external fixation is used, it is often necessary to fix the fracture of the diaphysis near the joint. For example, the wrist joint needs to be fixed for the distal radius fracture, which will easily cause joint stiffness after the fracture is cured; on the other hand, the material of plaster external fixation is relatively low. Thick and airtight, the patient's limbs at the fracture site are very uncomfortable, and it is easy to cause various physical and psychological problems for the patient

In addition to plaster external fixation, splint fixation is also a fixation method used in orthopedic clinics, but the splint fixation is not firm enough, and the stability is poor, so it is not suitable for fracture fixation of the backbone near the joint

Therefore, the current method of external fixation of the fracture site is difficult to achieve satisfactory results for doctors and patients, and it is very necessary to improve it.
