Problems solved by technology

If you have been positioning by X-ray exposure for a long time during the operation, it will cause great damage to the human body. Therefore, the positioning in the operation now often depends on the experience and skills of the doctor, and each doctor's level is different. Cause inaccurate positioning or even medical accidents

Embodiment

[0024] see Figure 1 to Figure 6 , the surgical positioning and navigation device in the embodiment of the present invention is based on the following concentric circle positioning principle: Since the refractive index of X-rays in different media is 1, the X-rays propagate in a straight line in different media, and are sent from the X-ray emitter to the image intensifier Or the X beam of the film is conical, and the conical beam can be regarded as being composed of gradually larger and continuous coaxial circles, assuming that there are three points A, B and C, if the images of these 3 points overlap on the X-ray projection film, then these 3 points must be on the same straight line as the light source O, and these 3 points correspond to the positions of the respective circles (the angles are the same as the centers of the respective circles, and the distances are proportional ),vice versa. see figure 1 .

[0025] From this, the point positioning principle of X-rays is sum...

Embodiment approach

[0031] D=in vivo target point (area, the same below), that is, the point that the doctor needs to find in the human body during the operation, that is, the point that the present invention needs to locate, such as the foreign body that needs to be found in the foreign body removal operation; D'=in vivo target Point D is the point displayed on the display screen of the C-arm machine by the X-rays emitted by the C-arm machine; E = body surface entry point (area, the same below), that is, the surgical point on the skin surface during surgery; F = lower positioning block (district, the same below); G=upper positioning block (district, the same below); F'=the point where the lower positioning block is displayed on the display screen of the C-arm machine by the X-ray development sent by the C-arm machine; G'= The point where the upper positioning block is developed by the X-ray emitted by the C-arm machine and displayed on the display screen of the C-arm machine.

Abstract

The invention relates to an operation positioning navigating device which is mainly used for positioning an operation position and performing operation navigation during medical operation so as to beused for various operations requiring positioning navigation. The operation positioning navigating device comprises an upper indicating plate, a lower indicating plate and an optical positioning navigating device, wherein the upper indicating plate is provided with an upper positioning block, and the lower indicating plate is provided with a lower positioning block. The operation positioning navigating device has reasonable structure and design, good service effect, rapidly and accurately positions the concrete positions of foreign bodies or pathological tissue inside a human body, increases the operation safety, improves the operation accuracy, and reduces the radiation exposure as well as operation wound.

Description

Technical field: [0001] The invention relates to a surgical positioning and navigation device, which is mainly used for positioning the surgical site and performing surgical navigation during medical operations, so as to be used in various operations requiring positioning and navigation. Background technique: [0002] Now for medical operations, a big problem is how to quickly and accurately locate the specific location of foreign bodies or diseased tissues inside the human body. If you have been positioning by X-ray exposure for a long time during the operation, it will cause great damage to the human body. Therefore, the positioning in the operation now often depends on the experience and skills of the doctor, and each doctor's level is different. Cause inaccurate positioning or even medical malpractice. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a ...
