Embodiment Construction

[0044] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0045] Clinical case:

[0046] Patient: Niu XX, male, 65 years old, suffering from left glossopharyngeal neuralgia, from Nanjing Drum Tower Hospital.

[0047] Make high-precision puncture navigation templates according to patient characteristics:

[0048] (1) Data acquisition: Data acquisition: use thin-slice CT scanning, set the scan layer thickness to 0.625mm, and scan pixels to 512×512 to obtain the head and face data of the patient; the specific collected data and images of the patient are as follows: Figure 1~4 shown;

[0049] (2) Import into medical software: Import the data generated in step (1) into medical software, and the specific steps to establish a three-dimensional model of head and face bones and skin are as follows:

[0050] A. First import the CT scan tomographic data into the medical modeling software in DICOM format, adju...

Abstract

The invention discloses a navigation template used for glossopharyngeal nerve navigation puncture and a navigation puncture method. The navigation puncture method is characterized in that a 3D imaging technique is adopted, a specific high-precision puncture digital navigation template is generated according to bone characteristics of a patient, and ultimately a high-precision puncture real navigation template is generated. According to the navigation puncture method, it can be guaranteed that puncture is accurately and properly carried out according to a preset puncture path and a needle insertion depth on the basis of the real navigation template, the success rate of an operation can be greatly improved, and harm to the patient is reduced; meanwhile, the navigation template and the navigation puncture method have the advantages that operation time is shortened, perspective radiant quantity is reduced, and operative complications are reduced. By means of the navigation puncture method, the navigation template is convenient to manufacture, the procedures are simple, manual operations are not needed, the automation degree is high, the navigation template is accurately manufactured, and the specific navigation template is made for the specific patient and accords with a humanized medical mode.

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...
