Embodiment 1

[0029] refer to figure 1 , a percutaneous infratemporal fossa-outer orbital wall endoscopic puncture guide plate in this embodiment includes a base plate, the base plate is composed of a base and a guide plate, and the base is an arc that fits the curvature of the outer scalp of the temporalis muscle Shaped plate, the front end of which is consistent with the curvature of the hairline; the base is provided with 4 observation holes; the front of the base is provided with a guide plate, which is integrally formed with the base; the guide plate is provided with a first guide hole and two second guide holes, the second guide holes are respectively located on both sides of the first guide hole, and the first guide hole and the second guide hole are integrally formed with the base.

[0030] The observation hole is square.

[0031] The first guide hole can place an endoscope, and the second guide hole can place surgical equipment such as a scalpel, suction device or straight / curved...

Embodiment 2

[0035] refer to figure 1 , a kind of percutaneous infratemporal fossa-outer orbital wall endoscopic puncture guide plate of the present embodiment, comprising 2 base plates, when the base plate is used, it is fitted symmetrically above the outer scalp of the temporalis muscle with respect to the human brain, and the base plate consists of a base and a guide plate Composition, the base is a curved plate that fits the curvature of the outer scalp of the temporalis muscle, and its front end is consistent with the curvature of the hairline; there are 4 observation holes on the base; a guide plate is provided in front of the base, and the guide plate Formed integrally with the base; the guide plate is provided with a first guide hole and two second guide holes, the second guide holes are respectively located on both sides of the first guide hole, the first guide hole and the second guide hole The hole is integrally formed with the base.

[0036] The observation hole is in the sha...

Abstract

A percutaneous infratemporal fossa-outer orbital wall endoscopic puncture guide plate, including 1 or 2 base plates, the base plate is composed of a base and a guide plate, the base is a curved plate that fits the curvature of the outer scalp of the temporalis muscle, and its front end and The hairline has the same curvature; the base is provided with an observation hole; the front of the base is provided with a guide plate, which is integrally formed with the base; the guide plate is provided with the first guide hole for placing the endoscope and 2 ultrasonic scalpels or The second guide hole of the suction device is located on both sides of the first guide hole respectively, and the first guide hole and the second guide hole are integrally formed with the base. The invention also discloses a usage method of the puncture guide plate. The puncture guide can shorten the operation time, has high compatibility with intraoperative surgical equipment and monitoring equipment, can reduce the probability of failure to locate the infratemporal fossa, and guide the outer wall of the orbit to open a window of about 3 cm2 to 4 cm2 to avoid excessive fenestration. Cerebrospinal fluid leaks, especially in patients with low dura mater in the anterior fossa.

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] Thyroid-associated eye disease ( thyroid ophthalmopathy ), 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] A...
