A navigation template and navigation puncture method for glossopharyngeal nerve navigation puncture

Abstract

The invention discloses a navigation template and a navigation method for glossopharyngeal nerve navigation and puncture. The innovation point is: using 3D imaging technology to generate a specific high-precision puncture digital navigation template according to the patient's bone characteristics, and finally generate a high-precision puncture physical navigation template. The navigation puncture method of the present invention is based on the physical navigation template, according to the pre-set puncture path and needle insertion depth, can ensure accurate puncture, in place, can greatly improve the success rate of surgery, reduce patient damage, and at the same time shorten the operation time and reduce fluoroscopy radiation The advantages of reducing surgical complications. The navigation puncture method of the present invention has the advantages of convenient manufacture, simple steps, no need for manual operation, high degree of automation, precise manufacture, and a specific navigation template according to a specific patient, which conforms to the current humanized medical model.

Description

technical field [0001] The invention relates to a navigation template used for the navigation puncture of the glossopharyngeal nerve, and also relates to a method for the navigation puncture of the glossopharyngeal nerve navigation template, which belongs to the field of medical devices. Background technique [0002] Primary glossopharyngeal neuralgia is a paroxysmal, severe pain in the distribution of the glossopharyngeal nerve. Pain occurs on one side of the base of the tongue, throat, tonsils, base of the ear, and back of the jaw. The pain usually comes on suddenly, showing knife-like, needle-like, tearing, burning, and electric shock-like pains. Drug therapy and nerve block therapy are often used clinically. For patients who are ineffective in drug therapy or elderly patients who cannot tolerate microvascular decompression, or patients with multiple sclerosis, radiofrequency thermocoagulation therapy with percutaneous jugular foramen is often used, which can play a role...

AI Technical Summary

Problems solved by technology

However, due to the deep position of the jugular foramen, it is difficult to locate it. Usually, repeated punctures and fluoroscopy are required to confirm the correct position before radiofrequency treatment can be performed.

[0004] In the traditional mode, clinicians perform anatomical positioning of the body surface according to the operating specifications, and perform punctures based on personal experience. Sometimes repeated punctures and repeated fluoroscopy are required, which will not only cause certain damage to the patient, but also may cause improper puncture.
