Problems solved by technology

[0005] However, the doctor needs to refer to the relationship between the surgical position and the dynamic position of the surgical instrument 130 in the two image information (such as coronal section and sagittal section) at the same time to adjust the surgical instrument 130 correctly, so the surgical guidance system is not fully utilized Experienced new doctors will need a period of time to learn and adapt. If a more visual and intuitive instrument guidance method can be developed to directly guide the doctor on how to adjust the surgical instrument 130, the learning process for the doctor can be greatly reduced. and the time spent on surgery

Embodiment Construction

[0032] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] As shown in 2 and 3, an instrument guidance method of an orthopedic surgery guidance system, the method S100 is executed in the computer system 70 . The method S100 includes the following steps: obtaining a predetermined instrument path 3D vector (step S10); obtaining a predetermined cutting plane (step S20); displaying a target mark on a display (step S30); reading a dynamic 3D vector (step S40); generating a projection vector (step S50); display two dynamic markers on the display (step S60) and guide the instrument to generate overlapping images (step S70).

[0034] When performing surgical guidance, if the imaging instrument used by the doctor is C-arm10, the calibrator 20 installed on the receiving end of the C-arm 10, the patient's surgical site 60, and the surgical instrument 30 are each equipped with a DRF 40 , the...

Abstract

The invention relates to the field of the medical orthopedics department, in particular to an apparatus guiding method of an operation guiding system for the orthopedics department. The method is executed in a computer system. The method comprises the following steps that 3D vector quantity of a predetermined path of an apparatus is obtained; a predetermined tangent plane is obtained; a display target is marked on a displayer; dynamic 3D vector quantity is read; projection vector quantity is generated; a second dynamic mark is displayed on the displayer and guides the apparatus to generate a superimposed image. The method comprises the advantages that firstly, a doctor can more visually know the relationship between the apparatus and the predetermined path of the apparatus; secondly, the operation can be accelerated; thirdly, the radiation dosage received by patients and medical workers can be reduced; fourthly, the learning time of doctors can be shortened.

Description

technical field [0001] The invention relates to the field of medical orthopedics, in particular to an instrument guiding method of an orthopedic surgery guiding system. Background technique [0002] In orthopedic surgery, physicians usually use a C-arm fluoroscopy X-ray machine (hereinafter referred to as C-arm) to repeatedly capture image information including surgical instruments and internal bones, and then determine the surgical location in the body based on personal clinical surgical experience. Using the spatial relationship between the surgical instrument and the surgical position in the image information, slowly adjust and move the surgical instrument to the surgical position. This method, in addition to relying heavily on the clinical experience of doctors, also makes patients and medical staff receive a large amount of radiation dose. [0003] Such as figure 1 As shown, in order to solve the problem that doctors need to repeatedly capture image information to obt...
