Embodiment Construction

[0033] The specific implementation of the embodiments of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments of the present invention.

[0034] see figure 1 , the embodiment of the present application provides a navigation device, including:

[0035] Navigation sign 10, connecting component 20 and fixing component 30;

[0036] The fixing assembly 30 is connected to the first end of the connecting assembly 20, the fixing assembly 30 is used to fix the surgical instrument, and the axis of the fixing assembly 30 coincides with the axis of the surgical instrument;

[0037] Specifically, the fixing assembly 30 can be cylindrical, and the axis of the fixing assembly 30 refers to the connection line between the center of the upper end of the cylinder and the center of the lower end of the cylinder. The main body of the surgical instrument is generally cylindrical, and the axis of the surgical instrument refers to Th...

Abstract

The invention provides a navigation device. The navigation device comprises a navigation identifier, a connecting assembly and a fixing assembly, the fixing assembly is connected with a first end of the connecting assembly and used for fixing a surgical instrument, and the axis of the fixing assembly coincides with the axis of the surgical instrument; the navigation identifier is connected with the second end of the connecting assembly, the navigation identifier is used for being sensed by the sensor module to obtain pose data for indicating the surgical instrument, and the pose data of the surgical instrument comprises position data of the surgical instrument and pose data of the surgical instrument. According to the navigation device provided by the embodiment of the invention, the axisof the fixing assembly coincides with the axis of the surgical instrument, so that the relative pose data of the surgical instrument relative to the navigation identifier is not changed when the surgical instrument rotates, the measurement error is reduced, and the navigation precision and the navigation accuracy are improved.

Description

technical field [0001] The embodiments of the present application relate to the field of instrument tracking, and in particular, to a navigation device. Background technique [0002] In recent years, with the development of research fields such as medical imaging technology and image processing technology, surgical navigation systems are playing an increasingly important role in the field of minimally invasive surgery. Surgical Navigation System (Surgical Navigation System) visualizes the local anatomical structure, locates the position of the lesion with high precision, effectively guides surgical instruments, expands the limited visual range of doctors, and makes surgical operations more accurate and safe. [0003] When doctors use the surgical navigation system to perform surgery, they need to observe and operate surgical instruments through the computer screen, so real-time tracking of surgical instruments is one of the key technologies of surgical navigation. Currently...
