Pelvic fracture reduction fixing suite

Abstract

The invention relates to a pelvic fracture reduction fixing suite which is used in cooperation with an X-ray machine and is characterized in that the pelvic fracture reduction fixing suite comprises afixing frame, an adjusting frame and a positioning cylinder. wherein the fixing frame is connected to a bed body; the head end of the adjusting frame is connected to the fixing frame, the adjusting frame comprises at least three sections of adjusting rods which are sequentially connected end to end and a connecting piece for connecting every two adjacent adjusting rods, at least one connecting piece is a connecting rotating shaft, and at least one connecting piece is a connecting sleeve; the positioning cylinder is connected to the tail end of the adjusting frame, the positioning cylinder isprovided with a first positioning hole suitable for a kirschner wire to penetrate through and two second positioning holes suitable for a stimulating needle of a nerve stimulator to penetrate through,and the two second positioning holes are parallel to the first positioning hole and symmetrically formed in the two sides of the first positioning hole. The pelvic fracture reduction fixing suite issimple in structure, easy to operate and full in mechanical structure, manual operation can be achieved, the direction can be changed universally, the direction can also be fixed, the kirschner wire can accurately reach the needed position, and the success rate of resetting and fixing is increased.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pelvic fracture reduction and fixation set. Background technique [0002] Pelvic fracture is a very serious and dangerous fracture. If the injury is serious, it will cause shock and even death. In every 100,000 people, about 20 to 37 people will suffer from pelvic fractures, accounting for about 0.3% to 6% of all fractures. The fatality rate of pelvic fracture without soft tissue or internal organ injury was 10.8%, and the fatality rate of complex pelvic trauma was 31.1%. In the pelvic cavity, there are also veins accompanying the arteries and an abnormally rich venous plexus. The area of ​​the latter is about 10 to 15 times that of the arteries and they are connected to each other. The bones of the pelvis are mainly cancellous bones, the pelvic wall has many muscles, and there are many arterial plexus and venous plexus nearby, so fractures can cause extensive bleeding. Th...

Problems solved by technology

However, the pelvis is irregular in shape and varies in thickness, so the positioning, direction, introduction, reset, and fixation are highly demanding and difficult to operate.
