Abstract

An embodiment of the present invention provides a positioning device and method in a medical image space. The device includes: an optical positioning unit, a first marking point, and a second marking point. The first marking point is set at the patient's surgical target position, and the second marking point Two marker points are set at the target position of the patient with reference to the first marker point unit, and a transformation matrix is ​​used to describe the coordinate relationship between the first marker point and the second marker point in the world coordinate system, and the optical positioning unit is used for the The first marker point is identified to obtain the coordinates of the first marker point in the world coordinate system, and according to the coordinates of the first marker point in the world coordinate system and the transformation matrix, the first marker point in the world coordinate system is obtained The coordinates of the two external punctuation points are used to complete the positioning of the automatic medical image space in the natural visible light environment according to the coordinates of the second marking point in the image space, thereby realizing the positioning of the automatic medical image space in the natural visible light environment.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical robots, and in particular, to a positioning device and method in a medical image space. Background technique [0002] Automation equipment such as robots has been widely used in the industrial field, showing obvious advantages in terms of operational flexibility, stability and accuracy. In order to solve the problems of insufficient precision, excessive radiation, large incisions, and operational fatigue in surgical operations, people have begun to discuss how to introduce robotic methods in surgical operations. The treatment method and system of the invention can solve the above problems and improve the surgical effect, that is, using medical robots to achieve surgical operations, including nerves, head and so on. [0003] In order to realize the operation, the localization in the medical image space must be solved. In the prior art, the spatial positioning methods of medi...
