Problems solved by technology

However, this method has great limitations. This method can only fix the human body, and all parts of the body cannot move. It is required to fix the patient during the CT imaging and operation process to ensure that the position is relatively static. , to improve precision and accuracy
Although these methods are used to determine the location of the disease and improve the accuracy, the accuracy is not high, the surgical incision is large, and it is easy to misdiagnose, so repeated operations are required, resulting in a further increase in the extent of the trauma

Embodiment 1

[0029] Such as figure 1 , a surgical navigation probe, including a needle bar 1 and a positioning assembly connected to the needle bar 1, the positioning assembly includes an upper positioning block 2 and a lower positioning block 3 on the same plane, and the upper positioning block 2 and the lower positioning block The surface of 3 is provided with a grid-shaped positioning grid, and the color difference of the filling color of adjacent positioning grids is relatively large. The intersection of four adjacent positioning grids is the positioning point, and the upper positioning block 2 Two positioning points are formed on the top, and one positioning point is formed on the lower positioning block 3; the two positioning points on the upper positioning block 2 and one positioning point on the lower positioning block 3 constitute a main positioning noodle;

[0030] The needle bar 1 is a straight rod, and one of the positioning points on the upper positioning block 2 is parallel ...

Embodiment 2

[0056] Example 2, such as image 3 As shown, different from Embodiment 1, the needle bar is a straight bar without bending in the middle of the needle bar.

Abstract

The invention relates to a surgical navigation probe, comprising a shank and a positioning component connected to the same. The positioning component includes an upper positioning block and a second positioning block on a same plane; the surface of each of the upper and lower positioning blocks is provided with a positioning grid in mesh form; the adjacent positioning grids have great color differences of filling colors; intersections of the four adjacent positioning grids; the upper positioning block is provided with two positioning points; the lower positioning block is provided with a positioning point; the two positioning points of the upper positioning block and one positioning point of the lower positioning block form a main positioning face. The invention also provides a surgical navigation device, comprising two high-definition cameras, a processor and a display. Accurate navigation can be provided, accurate judgment can be ensured for a disease part, and incision area is decreased.

Description

technical field [0001] The invention relates to a positioning tool, in particular to a surgical positioning appliance. Background technique [0002] Surgical positioning refers to finding the location of the disease, then accurately locating the point, and performing surgery according to the location to achieve precision medicine and reduce the area and scope of trauma. The usual surgical positioning is by taking CT images or X-rays, and then the doctor judges the size and location of the disease based on what he has learned. However, this method has a lot of subjectivity and requires the doctor to have rich anatomical experience to be accurate. Determine the position and size. Because the traditional CT machine can only capture a section when shooting an imaging film, which is equivalent to cutting the human body. The section view seen in this section is the imaged image, which is a two-dimensional plan view, not a three-dimensional one. As shown in the figure, the doctor...
