Navigation template used for trigeminal nerve navigation puncture and navigation puncture method

Abstract

The invention discloses a navigation template used for trigeminal nerve navigation puncture and a navigation puncture method. The main body of the navigation template is a template body, the template body is half of a face mask not higher than lower eyelids, a nose mask is arranged on the face mask integrally, a face mask rack is further arranged on the face mask integrally, and a puncture column is arranged on the face mask integrally. According to the navigation puncture method, 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 trigeminal nerve navigation puncture real navigation template is generated. The individual trigeminal nerve puncture navigation template is designed, the position and the structure of an oval foramen are definite in software, the puncture path is virtualized, harm to blood vessels and nerves along the path is avoided, the puncture depth is measured, and accordingly a puncture guide plate is generated. By means of the navigation method, puncture precision can be improved, operation time can be shortened, perspective radiation quantity is reduced and harm to the patient is reduced.

Description

technical field [0001] The invention relates to a method for navigating and puncturing the trigeminal nerve, which belongs to the field of medical devices. Background technique [0002] Primary trigeminal neuralgia is recurrent, short-lived and severe pain in the facial trigeminal nerve management area, which has the following characteristics: (1) episodic pain with pain-free intervals; (2) no clear positive signs of the nervous system; ( 3) There is a trigger point; (4) The pain is strictly limited to the innervated area of ​​the trigeminal nerve, and craniofacial pain caused by the following diseases must be excluded: cancerous facial pain, herpetic facial pain, periodic migraine neuralgia, SARS Facial neuropathic pain, etc. [0003] The pathogenesis of primary trigeminal neuralgia is unknown, there are various treatment methods, and a standardized treatment plan has not yet been established. At present, drug therapy, nerve block therapy, nerve damage therapy, and microv...
