Percutaneous infratemporal fossa-orbit outer wall endoscope puncture guide plate and application method thereof

Abstract

A percutaneous infratemporal fossa-orbit outer wall endoscope puncture guide plate comprises one or two base plates. Each base plate is composed of a base and a deflector, wherein the base is an arc-shaped plate attached to the radian of the temporalis outer scalp layer, and the front end of the base is consistent with the radian of hairlines; an observation hole is formed in the base; the deflector is arranged in front of the base, and the deflector and the base are integrally formed; the deflector is provided with a first guide hole containing an endoscope and two second guide holes capable of containing an ultrasonic scalpel or an aspirator, the second guide holes are located at the two sides of the first guide hole respectively, and the first guide hole, the second guide holes and the base are integrally formed. The invention further discloses an application method of the puncture guide plate. Through the puncture guide plate, operation time can be shortened, compatibility with operation equipment and monitoring equipment during an operation is high, the probability of failure in locating infratemporal fossa can be reduced, the windowing range on the orbit outer wall is guided to be 3 cm<2> to 4 cm<2>, and it is avoided that excessive windowing causes cerebrospinal fluid leakage, particularly a patient whose cerebral dura mater of anterior cranial fossa is low.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a percutaneous retro-hairline fossa-infratemporal fossa-outer orbital wall endoscopic puncture guide and a method for using the same. Background technique [0002] Thyroidophthalmopathy, also known as GraveS ophthalmopathy, infiltrating exophthalmos, thyroid-associated immune orbitopathy, etc., is one of the orbital diseases with the highest incidence rate, which can cause monocular and bilateral exophthalmos in adults. For patients with thyroid-associated ophthalmopathy with orbital dysplasia or malunion after orbital trauma, endoscopic minimally invasive decompression of the outer orbital wall through a posterior hairline approach is usually performed. Equipment and monitoring equipment Compatible with guide templates (referred to as guide plates) that guide the movement of scalpels and straight / curved nose drills. [0003] At present, with the help of computer ...
