Embodiment Construction

[0043] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments.

[0044] In current commercial products, optical or electromagnetic navigation equipment is usually used for final surgical tool position calibration. These robotic arms currently have the disadvantage of taking up surgical space in use.

[0045] Based on this, the present application provides a method, which adjusts the surgical tool based on the marked points. This method is conveniently applied to surgical tools of PET-CT / CT / MRI systems, as an adjustment scheme for surgical tools.

[0046] The marker point is located at the front end of the surgical tool, and the coordinates of the marker point in the coordinate system of the surgical tool are relatively fixed. There can be more than 2 marking points, such as 3, 4, 5, 6, 7 and so on. Optimally, there are 6 marking points.

[0047] The number of marked...

Abstract

The invention relates to a surgical tool adjusting method, electronic equipment and a clamping device. The method comprises the following steps: acquiring pixel coordinates of at least two mark pointsin an image, wherein the mark points are positioned at the front end of a surgical tool; determining areal coordinates of the mark points according to the pixel coordinates of the mark points; determining a rotating angle according to the areal coordinates of the mark points; and adjusting the surgical tool according to the rotating angle. The rotating angle is obtained according to the pixel coordinates of the mark points positioned at the front end of the surgical tool, the surgical tool is adjusted on the basis of the rotating angle, the final position calibration of the surgical tool by optional or electromagnetic navigation equipment is not required again, and occupation of surgical space is relieved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to an operation tool adjustment method, electronic equipment and a clamping device. Background technique [0002] In clinical practice, especially in tumor treatment, more and more medical images are used as guidance, and then navigation devices are used to locate surgical tools, so as to perform minimally invasive surgery, reduce patient wounds, and speed up patient recovery. [0003] Due to the doctor's experience and the complexity of the actual operation, it is usually necessary to guide the surgical tool to the designated point and direction strictly according to the surgical plan. [0004] In current commercial products, optical or electromagnetic navigation equipment is usually used for the final position calibration of surgical tools, such as the Polaris system of NDI Company. [0005] These robotic arms currently have the disadvantage of taking up surgical space in...
