Problems solved by technology

[0005] It can be seen that the above-mentioned existing surgical image positioning method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

Abstract

The invention relates to a positioning method realized by the aid of a C-shaped arm and a guiding system. The positioning method includes following steps: providing the C-shaped arm with an image corrector; obtaining a coordinate conversion relational expression; obtaining a relative space relational expression; moving the C-shaped arm; shooting for the first time; marking a point to be shot; and shooting for the second time. By the aid of the coordinate conversion relational expression and the relative space relational expression, shooting is carried out for the first time after space relation is calculated and positioning is realized, then the interested point to be shot is marked, shooting is carried out for the second time, a wound part can be adjusted to a shooting position only by twice shootings, so that shooting frequency can be reduced, and the quantity of radiation exposed under X rays is reduced.

Description

technical field [0001] The invention relates to a positioning method of an operation image, in particular to a positioning method by combining a C-arm and a guiding system. Background technique [0002] In traditional orthopedic surgery, the biggest factor that determines the patient's range of motion is the accuracy of the placement of the bone nails. However, the relative positions of the bones are three-dimensional, and the bones are hard and opaque. Due to the skin and flesh, the doctor cannot see the position of the bones with the naked eye during the operation. Therefore, in the current orthopedic surgery, it is necessary to obtain multiple images of the bones through X-ray irradiation, and then the doctor can make further decisions based on the images. Surgical pathway or placement of bone screws. [0003] The C-arm is a type of X-ray imaging equipment. It has the characteristics of high mobility and can continuously update the image during the operation. It is curre...
