Surgical guidance model, head-mounted wearable device-assisted surgical navigation system

Abstract

The present invention provides a surgical guidance model, a head-mounted wearable device-assisted surgical navigation system and method, and the head-mounted wearable device includes: an image acquisition module for acquiring image data of a patient's surgical image through the image acquisition device, wherein , the image data includes the surgical guide model set at the patient's surgical position; the image processing module is used to identify the position of the surgical guide model in the image data and the surgical tool position of the surgical tool held by the doctor through image recognition technology. The position of the guide model and the position of the surgical tool are displayed to the doctor together with the preset surgical guide model and the three-dimensional model of the surgical tool and the image data; the positioning and navigation module is used to determine the relative position of the surgical guide model and the surgical tool Whether the preset conditions are met, and if so, the navigation completion information is fed back to the doctor, and the present invention can ensure the correct implementation of the treatment plan.

Description

technical field [0001] The invention relates to the technical field of wearable medical equipment, in particular to a surgical guidance model, a head-mounted wearable device-assisted surgical navigation system and method. Background technique [0002] In the prior art, radiotherapy (radiotherapy) is one of the important treatment methods for tumors. In order to minimize the side effects of radiotherapy and the damage to normal tissues caused by radiotherapy, radioactive seed implantation therapy technology (hereinafter referred to as seed implantation) has been developed. [0003] Adhering to the development of medical technology, in the current clinical practice of particle implantation, medical scan data, such as CT scan data and MRI scan data, can be obtained by scanning patients with medical imaging equipment. Doctors can delineate the tumor lesion area and the treatment target area of ​​implanted seeds based on the medical scan data, and formulate a treatment plan. Th...

Problems solved by technology

[0004] However, the surgery-guided model can only guide the doctor to perform the needle. The doctor cannot directly observe whether the puncture needle has been punctured in place, nor can he determine whether the puncture needle has been punctured in place. It still needs to be judged by experience or by CT scan after seed implantation Whether the puncture is in place, resulting in a decrease in the accuracy and efficiency of seed implantation surgery
