Positioner for orbital wall decompression surgery under endoscope

Abstract

The invention relates to a positioner for an orbital wall decompression surgery under an endoscope, which comprises a positioning seat capable of being fixed at a base point on a lower orbital bone and a triangular positioning guide plate which is formed by connecting a bottom, a first side part and a second side part end to end and can be inserted into an orbital, the bottom and the first side part intersect to form an angle A larger than 20 degrees and smaller than 60 degrees, the first side part and the second side part intersect to form an angle B larger than or equal to 90 degrees and smaller than 120 degrees, the positioning seat is arranged at the intersection of the bottom of the positioning guide plate and the second side portion, and a clamping groove capable of being clamped at the base point of the lower orbital bone is formed in the positioning seat in a concave mode. By the adoption of the technical scheme, the problem that in an existing ophthalmic surgery, when a surgical instrument goes deep into an orbital to treat the bone wall in the orbital or the surgical instrument moves in the orbital, the surgical instrument is prevented from going deep into and touching brain nerves, and the possibility of secondary injury to an operator is caused is solved.

Description

Technical field[0001]The present invention relates to the field of medical devices, particularly a locator for decompression surgery for endoscopic wall decompression surgery.Background technique[0002]Under endoscopic diaphragm diameter pathway reduced pressure surgery. The surgical way is fundamentally avoided by two major complications of the temporal background, with minimally invasive, clear effect, less complications.[0003]However, under the surgical operation of endoscopic, due to the small space, the depth of the medical instrument into the eyelid and the high degree of experience controlled by the doctor, however, the upper and rear of the outer walls of the border are craniocene, once the medical device rejects into the eyelid The depth and high grasp will result in serious consequences, so there is an urgent need for a locator that can reduce the risk of decompression surgery in minimally invasive walls.Inventive content[0004]For an object of the present invention: in orde...

AI Technical Summary

Problems solved by technology

[0003] However, due to the narrow space of the surgical operation under the endoscope, the depth and height of medical instruments inserted into the orbit are all controlled by the doctor's experience. However, the top and rear of the outer orbital wall are the brain. Improper grasp of depth and height will lead to serious consequences, so there is an urgent need for a positioner that can reduce the risk of minimally invasive orbital wall decompression surgery
