Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] Such as figure 1 As shown, the embodiment of the present invention provides an application environment diagram of a surgical navigation system based on a radio frequency positioning chip. The navigation system is mainly used to remove the lesion tissue 3 in the organ 2 to be operated. Focus beacon 4, in order to prevent the large blood vessel 6 in the organ from being destroyed during the operation, a plurality of blood vessel beacons 5 are set around the blood vessel, and a scalpel beacon 8 is set on the scalpel 7 for real-time navigation, and By setting the corresponding detector 1 to rec...

Abstract

The invention belongs to the technical field of microcosmic radio positioning navigation, and relates to a surgical navigation system based on a radio frequency positioning chip. Beacons capable of transmitting signals are used for marking focuses and blood vessels, a scalpel is positioned in real time, a detector is used for receiving related signals, the distance between each beacon and the detector is obtained according to an RSSI distance measurement method, a real three-dimensional coordinate system is constructed, coordinates of each beacon are obtained, and the positioning accuracy of the scalpel is improved. A Kalman filtering algorithm metal detection technology is combined to carry out beacon position correction on a beacon, a virtual three-dimensional coordinate system is constructed through three-dimensional fusion of a corresponding CT image, and a real-time navigation coordinate system is obtained through mapping. Finally, the effects of assisting the operation, improving the accuracy, shortening the operation time and reducing the trauma are achieved.

Description

Technical field [0001] The invention belongs to the technical field of microscopic radio positioning and navigation, and relates to a surgical operation navigation system based on a radio frequency positioning chip. Background technique [0002] In the early stage of cancer, surgical resection is mainly used for treatment. Since the tissue is not transparent and there are a large number of blood vessels, the difficulty of surgery is greatly increased. [0003] In the prior art, there are mainly two surgical navigation methods, one is the traditional non-computer navigation intraoperative positioning method, which specifically includes: 1. According to the preoperative imaging examination, endoscopic examination, physical examination and other methods obtained Information, to judge the location of the lesion and its relationship with the surrounding anatomical structure, the surgeon can identify the anatomical structure adjacent to the lesion during the operation, combined wi...
