Bone malformation correction or fracture reduction and fixation device and method for processing same

Abstract

The invention discloses a bone malformation correction or fracture reduction and fixation device and a method for processing the same. The bone malformation correction or fracture reduction and fixation device comprises external fixation brackets or one and more external fixation plates, wherein the external fixation brackets or the external fixation plates are used for fixing fixation needles inserted into the bone tissues; at least one end of each fixation needle is exposed outside the skin, and the exposed end of the fixation needle needs to be fixed; the external fixation brackets consist of a first fixation bracket and a second fixation bracket; the external fixation plates are used for fixing all the fixation needles inserted into the bone tissues needing to be fixed. The method for processing the bone malformation correction or fracture reduction and fixation device comprises the following steps of: (1) collecting the information of an image before reducing the bone; (2) reducing the bone virtually by using a computer; (3) designing the structure of the bone malformation correction or fracture reduction and fixation device; and (4) processing the bone malformation correction or fracture reduction and fixation device. The bone malformation correction or fracture reduction and fixation device provided by the invention has a function of automatically reducing the bone, is reasonable in structure, has a good bone fixing effect and can be used for effectively overcoming the defects of difficult bone malformation correction or fracture reduction, complex operation on malformed or fractured bone and excessive dependence on the clinical experience of a doctor of the existing bone malformation correction or fracture reduction and fixation mode.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent application with the application date of December 5, 2013, the application number 201310654003.2, and the invention creation name "An orthopedic deformity correction and fracture reduction fixation device and its processing method". technical field [0002] The invention belongs to the technical field of orthopedic orthopedics and reduction, and in particular relates to an orthopedic deformity correction and fracture reduction and fixation device and a processing method thereof. Background technique [0003] Reduction is a basic and very important operation in the treatment of fractures or deformities, and its effect directly affects the operation results 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 satisfactory. The e...

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

[0004] 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

[0005] 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

[0006] 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.
