Abstract

The embodiment of the invention provides a cursor ruler. The cursor ruler comprises a bracket and at least three markers, wherein the markers are fixed on the bracket; at least three markers of whichthe geometric centers are non-collinear exist in all the markers; one or more of dimensions and shapes of any two markers are different, and any different markers are not in mutual contact; and through the materials of the markers and the bracket, in three-dimensional images obtained through a three-dimensional imaging technique, the difference between the gray scale of the markers and that of thebracket exceeds a firs preset value. The embodiment of the invention also provides a method for registering a coordinate system. The embodiment of the invention also provides a method for registeringthe coordinate system using the cursor ruler.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of automatic surgery, and in particular to a method for registering an optical scale and a coordinate system. Background technique [0002] Automatic surgery (navigation surgery) means that the surgical robot automatically performs the required surgical operation on the patient according to the preset surgical plan (for example, drilling a hole at a specific position of a specific spine), which has the advantages of precise operation, no mistakes, It is not easy to be infected, does not consume labor, and has the advantages of high efficiency. [0003] The process of automatic surgery usually uses three-dimensional imaging technology to obtain a three-dimensional image of the patient, and the doctor marks the surgical plan in the three-dimensional image, and then the surgical robot automatically performs the operation on the patient according to the surgical plan. [0004] Since t...
