Problems solved by technology

This operation achieves the purpose of drainage by cutting through the wall of the eyeball. Cutting through the wall of the eyeball not only destroys the integrity of the eyeball wall, but also greatly increases the chance of eyeball infection, and the ability of the eyeball to withstand external trauma after surgery is reduced

Abstract

The invention discloses an inserting part of an endoscope, comprising an endoscope body and an operation tool installed on the endoscope body. The operation tool is hard, and has the functions of bluntly separating, moving and actually cutting on a tissue structure in a projection scope of an optical lighting system in the endoscope body. The inserting part of the endoscope can be extended into the angle of the anterior chamber of an eye through a cornea cut to conduct operations such as separating, cutting and foreign matter-taking out on the angle of the anterior chamber and the recess of achamber angle, thereby separating the chamber angle under observation by the endoscope, greatly improving the availability and safety of closed-angle glaucoma, and providing a new choice for treatingforeign matter in chamber angle.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an endoscope insertion part. Background technique [0002] Glaucoma is a group of eye diseases characterized by the death of retinal ganglion cells caused by an absolute or relative increase in intraocular pressure, and the common clinical manifestations are increased intraocular pressure, visual field defect, pallor of the retina, and enlarged cup-to-disk ratio. Glaucoma is a common and frequently-occurring disease in ophthalmology. Because of the irreversible characteristics of blindness, most of the patients are chronic and the symptoms are hidden. Most patients are not discovered until the late stage or after blindness in one eye, which brings difficulties to the diagnosis and treatment of glaucoma. Glaucoma is currently one of the leading causes of blindness worldwide. [0003] Glaucoma is divided into open-angle type and angle-closure type according to the state of the c...
