Orthopedics department deformity correction and bone fracture reduction fixing device and processing method of fixing device

Abstract

The invention discloses an orthopedics department deformity correction and bone fracture reduction fixing device and a processing method of the fixing device. The fixing device comprises an outer fixing frame or an outer fixing plate, wherein the outer fixing frame or the outer fixing plate is used for fixing needles inserted into the bone tissue, at least one end of the fixing needles is exposed out of the skin, in addition, the end part, exposed out of the skin, of the fixing needles is the end to be fixed, the outer fixing frame comprises a first fixing frame body and a second fixing frame body, the outer fixing plate is a fixing plate used for fixing all of the fixing needles inserted into the bone tissue to be fixed, and the outer fixing plate comprises one or several fixing plate blocks. The processing method comprises the following steps of image information collection before reduction, computer virtual reduction, fixing device structural design and fixing device processing. The fixing device provided by the invention has the advantages that the automatic reduction function is realized, the structure is reasonable, the fixation effect is good, and the defects of reduction deformity correction difficulty, surgery operation complexity, overdependence on the clinic experience of doctors and the like in the existing bone fracture reduction or deformity correction process can be effectively overcome.

Description

Technical field [0001] The invention belongs to the technical field of orthopedics and reduction, in particular to a fixation device for orthopedic deformity correction and fracture reduction and a processing method thereof. Background technique [0002] Reduction is a basic and important operation in the treatment of fractures or deformities, and its effect directly affects the results of surgery and postoperative recovery. Therefore, in the surgical treatment of fractures or deformities, reduction is required first, and internal fixation or external fixation is adopted after the reduction is satisfied. The effect of reduction will directly affect the effect of the operation. Although open reduction is relatively easy, there are large traumas. Bleeding, susceptible to infection, high requirements for the skin, damage to the periosteum, it is easy to cause defects and deficiencies such as nonunion of fractures, and closed reduction mainly depends on the clinical experience of the...

AI Technical Summary

Problems solved by technology

Therefore, in the surgical treatment of fractures or deformities, reduction is required first, and internal fixation or external fixation is adopted after the reduction is satisfactory. The effect of reduction will directly affect the effect of surgery. Although open reduction is relatively easy, there are large trauma, Bleeding, susceptibility to infection, high requirements on the skin, fracture nonunion after periosteum damage, and other defects and deficiencies, while closed reduction mainly relies on the clinical experience of doctors, and X-ray machine perspective is needed to confirm the alignment of bones, which has great potential Large uncertainty, sometimes difficult to reset, doctors need to be directly exposed to X-rays, which seriously damages the health of patients and doctors

[0003] In addition, when the reduction is satisfactory, in order to ensure the stability of the fracture end, both internal fixation and external fixation must have sufficient strength. If the strength is too high, the fracture end will not have the stress stimulation required for fracture healing, so it is easy to occur. Fracture nonunion or delayed union, even if union is finally achieved, the strength of the fracture site is lower than normal bone, and when the fixation is removed, it is easy to fracture again

[0004] During the surgical treatment of deformity correction, it is more dependent on the doctor’s clinical experience. Although the scope and degree of correction can be preliminarily determined with the help of preoperative examination, it is mostly determined by the doctor’s judgment during the operation, and it is inevitable that there will be judgment bias or Other uncertain factors, and the internal fixation often needs to be repeatedly bent, which is not only time-consuming and laborious, but also reduces the strength of the internal fixation material. In addition, when the deformity is serious, one-time correction is easy to damage the nerves, blood vessels, skin, etc., so the traditional method only Multiple operations can be performed, which will not only increase the pain of the patient, increase the cost of treatment, increase the risk of surgery, increase the treatment cycle, but also affect the treatment effect

[0005] To sum up, the existing methods of fracture reduction or deformity correction have defects and deficiencies such as difficulty in reduction or correction, cumbersome surgical operations, excessive reliance on doctors' clinical experience, and fracture healing due to firm fixation.
