Abstract: A precision detection method for detecting the precision of a surgical robot positioning system includes: acquiring spatial position coordinates of a first detection point and a second detection point; acquiring information of a spatial axis for a surgical robot reaching a planned path, wherein the planned path is formed based on the first detection point and the second detection point; and calculating a first distance from the first detection point to a spatial axis and a second distance from the second detection point to the spatial axis. The precision detection method for a surgical robot positioning system can accurately detect the precision of the surgical robot positioning system.

Abstract: A tracing device is used for indicating the spatial position of a mechanical arm of a surgical robot. The tracing device includes: a base having two opposite ends and an outer circumferential surface located therebetween, one end is connected to an operation end of the mechanical arm, and a surgical instrument is installed at the other end; and a positioning assembly connected to the base and used for indicating the spatial position of the base. A positioning assembly includes at least three tracing elements arranged on the outer circumferential surface in a non-collinear manner. A plurality of positioning assemblies are distributed in a circumferential direction of the base; and a normal angle between any two of the tracing elements of each positioning assembly is smaller than or equal to 20°.

Abstract: The invention provides a probe device, a precision detection method, a precision detection system, and a positioning system. The probe device includes a positioning part and a guide detection part, wherein the positioning part is provided with a support having three or more non-collinear positioning element installed thereon, and the guide detection part is connected with the support, has a first preset positional relation with the positioning elements, and has a cylindrical outer contour matched with a guide element of the positioning system. The precision of the guide element can be accurately detected, so that the control precision of a surgical robot is effectively improved, and the system safety is improved.

Abstract: The disclosure relates to a surgical positioning apparatus, positioning system and positioning method. The positioning apparatus comprises a bracket, on which three or more reflecting balls for reflecting infrared and four or more positioning markers opaque to X-ray are provided. The disclosure provides both the reflecting balls for reflecting infrared and the positioning markers on the bracket, thus the reflecting balls can be identified by an optical tracking device, and the positioning markers can be scanned and identified by a three-dimensional device.
