Retrobulbar optic nerve exposer

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a retrobulbar optic nerve exposer specially made for an optic nerve sheath windowing operation. The retrobulbar optic nerve exposer comprises a handle and a blunt body, wherein the blunt body is fixedly arranged at the front end of the handle; the blunt body is a flat arc; the front end of the blunt body is forked; and inner and outer edges of the blunt body are smooth. According to the retrobulbar optic nerve exposer provided by the invention, retrobulbar optic nerves at the back of eyeballs can be conveniently and safely probed, and surrounding tissues of the optic nerves are accurately and firmly pushed aside, so that the optic nerves are exposed, and the windowing operation can be conveniently performed on optic nerve sheaths by using an incision knife subsequently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a retrobulbar optic nerve exposer specially made for optic nerve sheath fenestration. Background technique [0002] Due to the "intracranial sagittal sinus thrombosis, causing intracranial hypertension", the optic nerve is oppressed, resulting in blurred eye imaging, gradual decline in vision, accompanied by headache, dizziness, and tinnitus. At present, it has been successfully created clinically - optic nerve Sheath fenestration has a good therapeutic effect on this ophthalmic disease. Optic nerve sheath fenestration cuts off the eye muscles under a microscope, then turns the eyeball outward to expose the optic nerve sheath, and cuts a thin opening in the optic nerve sheath to allow the intracranial cerebrospinal fluid to flow out along the incision, lowering the intracranial Pressure, maximum relief of high intracranial pressure on the optic nerve compression, save the patient'...

AI Technical Summary

Problems solved by technology

The common nerve dissector currently used is usually made of a thin, flat metal rod. However, due to the limited space for orbital manipulation and the smooth surface of the optic nerve sheath, it is difficult to dissect the nerve smoothly when using a common dissector. Pull away the tissue around the optic nerve, making the operation difficult, reducing the efficiency of the operation, and prone to nerve damage
