Abstract

The invention discloses a multifunctional controllable depth foramen ovale intervention guide in the field of medical instruments, comprises a plate body and a catheter connected to the plate body, wherein the plate body comprises a cover nose part covered on the nose, the left end and the right end of the cover nose part both extend outwardly to form a face contacting part, the face contacting part located on the left side of the cover nose part extends downwardly to form a puncture part, and the catheter is located on the puncture part. The invention can solve the problem that the direction,the angle and the depth need to be manually controlled in the puncture intervention of the foramen ovale in the prior art, and the error rate is high.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multifunctional and controllable depth foramen ovale intervention guide. Background technique [0002] The foramen ovale at the base of the skull is located on both sides of the middle cranial fossa, and at the medial rear edge of the greater wing of the sphenoid bone. The trigeminal nerve passes through the foramen ovale. The trigeminal nerve is a pair of the largest cranial nerves in the skull and is a mixed nerve. . The trigeminal nerve is further divided into three branches, the ophthalmic branch, the maxillary nerve and the mandibular nerve, among which the mandibular nerve exits the cranium through the foramen ovale. Trigeminal neuralgia refers to recurrent paroxysmal severe neuralgia in the distribution area of ​​the facial trigeminal nerve. It is one of the difficult and miscellaneous diseases recognized at home and abroad. Talking, brushing teeth, or breeze blowing on ...
