Problems solved by technology

[0003] However, in the use of the current surgical guidance system, whether it is preoperative images or real-time images (for example: ultrasound can provide real-time images), doctors must focus on watching the images provided by the surgical guidance system and the patient The location of the physical surgical space is likely to cause inconvenience to the doctor during the operation, and even increase the error in the operation

Abstract

The present invention provides a surgical guidance system and its instrument guidance method, comprising: obtaining three-dimensional space information of a predetermined instrument path of an instrument; transmitting the three-dimensional space information to a processing unit, so that the processing unit uses a projection model algorithm Converting three-dimensional spatial information into two-dimensional spatial information; and making at least two image projection units respectively receive the two-dimensional spatial information to respectively project at least two patterns in a physical space, wherein the two patterns intersect to form an intersection area.

Description

technical field [0001] The present invention relates to an operation guidance system and its instrument guidance method, in particular to an operation guidance system and its instrument guidance method which can provide optical guidance to increase the convenience of operation. Background technique [0002] In many minimally invasive surgeries today, doctors often only perform operations based on preoperative images or real-time image data, and such systems that assist doctors in performing operations can be called surgical guidance systems. Currently common surgical guidance systems include, for example, the application of ultrasound imaging or infrared imaging combined with preoperative imaging (such as magnetic resonance imaging, computed tomography, and X-ray imaging). [0003] However, in the use of the current surgical guidance system, whether it is preoperative images or real-time images (for example: ultrasound can provide real-time images), doctors must focus on wat...
