Abstract

The present application relates to a beam positioning method, a guide channel positioning method and a positioning mechanism. The beam positioning method includes the steps: acquiring position information of a first intersection point formed by an intersection of a light beam and a detection area on an optical detection device, the light beam including a positioning light beam and an interferencelight beam, the positioning light beam pointing toward a target point of a diseased limb; acquiring position information of a second intersection point formed by the intersection of the interference beam and the detection area on the optical detection device; and calculating coordinates of the positioning beam on the detection area based on position information of the first intersection point andposition information of the second intersection point.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a beam positioning method, a guide channel positioning method and a positioning mechanism. Background technique [0002] At present, in the field of medical technology, when it is necessary to perform surgical operations on internal targets through external surgical instruments, it is usually necessary to set marker points on the surgical instruments, and then obtain the real-time position of the marker points by an external shooting device to determine the surgical operation. The position of the instrument in the body, to determine whether the operation touched the peripheral nervous system or to determine whether the surgical instrument reached the target in the body. [0003] In a related art, the position of a surgical instrument can be determined using a light beam directed at a target in the body. However, in this related technology, due to the influence of ambi...
