Description
Technical Field
The utility model relates to an external fixation frame technical field that resets in the fracture of pelvis art specifically is an external fixation frame that resets in the fracture of pelvis art.
Background
The pelvic fracture is a very serious and dangerous fracture, if the injury is serious, the patient can be shocked and even die, about 20-37 of every 10 ten thousand of people can have pelvic fractures, the pelvic fractures account for 0.3-6% of all fractures, the fatality rate of pelvic fractures with uncomplexed soft tissues or organ injuries is 10.8%, the fatality rate of complicated pelvic injuries is 31.1%, veins and abnormal abundant venous plexus which accompany the arteries are arranged in the pelvic cavity, and the area of the veins and the venous plexus is 10-15 times of the arteries and are communicated with each other. The early death of patients with severe pelvic multiple injuries mostly occurs from minutes to hours after injuries, which accounts for about 30 percent of the total death, the fracture bleeding is the leading cause of death of patients with pelvic fractures, the more unstable the pelvic fractures are, the larger the corresponding bleeding is, the more dangerous the patients with larger bleeding amount are, so the early reduction and fixation of the fracture are very important, the pelvic fractures are a common disease, the treatment methods are many, and the methods of traction, operation, medicine and the like exist at present.
The premise of minimally invasive surgical treatment is accurate reduction of unstable pelvic fracture displacement, closed reduction of pelvic fracture has the advantages that the risk of vascular nerve injury caused by soft tissue exposure in incision surgery can be reduced to the maximum extent, accurate reduction is one of the most important and difficult links before final fixation of pelvic fracture is carried out, precise closed reduction of pelvis is important to implement due to deep pelvic position and irregular shape, but the traditional closed reduction process completely depends on manual operation of an operator, technical requirements on the operator are high, the whole process needs to be carried out under X-ray monitoring in the operation, and radiation exposure to medical staff is overlarge.
The traditional treatment mode is incision reduction internal fixation, which can look directly at the damaged area and is beneficial to anatomical reduction, but the pelvic surgery approach needs a large incision and wide soft tissue stripping, so that the healing problems of important vascular nerve injury risk, incision infection and the like are increased, the subsequent surgical treatment is very troublesome, the closed reduction pelvic fracture can be realized, the minimally invasive screw fixation technology can avoid the above intraoperative or postoperative complications caused by incision reduction, and the minimally invasive screw fixation technology gradually becomes a method for treating pelvic fracture for orthopedists.
