Description

Customized intelligent drug release monitoring trigeminal nerve block microneedle system Technical Field The invention relates to the technical field of medical appliances, in particular to a customized intelligent drug release monitoring trigeminal nerve block microneedle system. Background Trigeminal neuralgia is a common cranial nerve disease, the pathogenesis of which is mostly related to factors such as vascular compression of the semilunar node of the trigeminal nerve, demyelinating lesions of nerves and the like, and the clinical manifestation of the trigeminal neuralgia is severe and transient pain repeatedly attacks in the distribution area of the facial trigeminal nerve, which seriously affects the life quality of patients. The trigeminal neuralgia blocking treatment is an important means for clinically controlling pain and radically curing diseases at present, and is a main stream treatment mode of the trigeminal neuralgia at present, and the trigeminal neuralgia blocking operation needs to accurately acquire the position of percutaneous foramen ovale and then deliver blocking drugs through the position of the foramen ovale. The foramen ovale is used as the unique osseous channel for the semi-lunar node of the trigeminal nerve to enter and exit the cranial cavity, is positioned in the deep part of the skull base, the body surface cannot be directly observed, and the surrounding is adjacent to important anatomical structures such as internal carotid artery, cavernous sinus, optic nerve and the like, the accuracy of a puncture path directly determines the safety and treatment effect of the operation, and once the puncture is deviated, serious complications such as vascular injury, nerve injury, intracranial hemorrhage and the like are extremely easy to cause, and even the life of a patient is endangered. In the prior art, the acquisition of the position of the oval foramen is mainly combined with the perspective image of a C-arm X-ray machine to perform freehand puncture operation. Specifically, a doctor obtains a perspective image of the foramen ovale at the skull base of a patient through a C-arm X-ray machine, determines a puncture point, a puncture angle and a puncture depth through experience, manually controls the puncture needle to puncture, repeatedly adjusts the angle and the direction of the puncture needle in the puncture process, and performs real-time perspective verification on whether the puncture position is accurate or not through the C-arm X-ray machine. However, the existing puncture mode has a plurality of defects, and is difficult to meet the requirement of accurate treatment, namely, firstly, the accuracy of bare-handed puncture is highly dependent on the clinical experience of doctors, the operation levels of different doctors are different, the problems of puncture angle deviation, improper depth control and the like are easy to occur, puncture failure or complications are caused, and the standardized development of operation is not facilitated, the existing C-arm X-ray machine can only provide perspective images, mechanical limiting and guiding cannot be performed on a puncture path, the doctors need to continuously stare at the images and manually adjust the puncture needle in the puncture process, the operation difficulty is high, hand tremble is easy to occur in long-time operation, the puncture precision is further influenced, finally, in the existing puncture operation, a special positioning component is lacked to determine puncture points and puncture angles, the doctors need to repeatedly probe positions of oval holes through metal probes, the operation is complicated, the risk of puncture deviation still exists in the probing process, the operation time is prolonged, and the pain and the operation risk of patients are increased. Therefore, aiming at the technical problems of low percutaneous foramen ovale puncture precision, high operation difficulty, poor safety, lack of effective positioning guide mechanism and the like in the prior art, a trigeminal nerve blocking microneedle system capable of realizing accurate three-dimensional positioning of the foramen ovale, simplifying puncture operation and improving operation safety and precision is developed and becomes a technical problem to be solved urgently by the prior art. Disclosure of Invention In order to solve the technical problems in the prior art, the application provides a customized intelligent drug release monitoring trigeminal nerve block microneedle system. The technical scheme includes that the customized intelligent drug release monitoring trigeminal block microneedle system comprises a radiography mechanism, a positioning mechanism and a positioning mechanism, wherein the radiography mechanism comprises a workbench, a C-shaped arm, an X-ray tube and an image detector, the C-shaped arm is rotatably arranged on the workbench, the X-ray tube and the image detector are respectively arranged at two ends o
