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 f

Embodiment 1

[0076] like figure 2 , image 3 and Figure 4 An orthopedic deformity correction and fracture reduction and fixation device shown includes an external fixator for fixing a fixation pin 1 inserted into the bone tissue to be fixed, at least one end of the fixation pin 1 is exposed outside the skin and the end exposed outside the skin The part is the fixed end. The bone tissue to be fixed is the bone tissue that needs to be reduced or corrected due to a fracture or the bone tissue that is adjacent to the bone tissue that has a fracture or deformity.

[0077] The external fixator includes a first fixation frame body 2-1 for fixing the fixation pin 1 inserted into one end of the bone tissue to be fixed and a second fixation frame body 2 for fixing the fixation pin 1 inserted into the other end of the bone tissue to be fixed -2, the first fixing frame body 2-1 and the second fixing frame body 2-2 are connected as a whole through a frame body connecting piece. Both the first fix...

Embodiment 2

[0132] In this embodiment, the difference from Embodiment 1 is that the external fixator further includes a third fixator body located between the first fixation frame body 2-1 and the second fixation frame body 2-2, the first fixation frame body The three fixed frame bodies are connected as one with the first fixed frame body 2-1 and the second fixed frame body 2-2 through the frame body connectors, and the third fixed frame body is provided with a fixed frame for the fixed end to be fixed. The fixing hole 3.

[0133] In actual use, the number of fixing holes 3 opened on the third fixing frame is one or more, and the fixing pin 1 inserted between the distal and proximal ends of the bone tissue to be fixed is fixed by the third fixing frame.

[0134] In this embodiment, the structure, size and connection relationship of other parts of the external fixator are the same as those in Embodiment 1.

[0135] In this example, using figure 1 The processing method shown is for proces...

Embodiment 3

[0137] In this embodiment, the structure, size and connection relationship of the processed external fixator are the same as those in Embodiment 1.

[0138] In this example, using figure 1 When processing the external fixator in the shown processing method, the difference from Example 1 is that in step 4, when processing the first fixture body 2-1 and the second fixture body 2-2, first The frame bodies used for the first fixed frame body 2-1 and the second fixed frame body 2-2 are processed, and then the drilling equipment is used to process the fixing holes 3 on the processed frame body to obtain the processed and formed first fixed frame body. The frame body 2-1 and the second fixed frame body 2-2.

[0139] That is to say, when processing the first fixing frame body 2-1 and the second fixing frame body 2-2, traditional machining methods can also be used.

[0140] During actual processing, the frame bodies of the first fixed frame body 2-1 and the second fixed frame body 2-...

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...
