Abstract

The utility model relates to the field of medical apparatuses and instruments, in particular to a retrobulbar optic nerve exposure device which is specially manufactured for being used for optic nerve sheath windowing operations. The retrobulbar optic nerve exposure device comprises a handle and a blunt body fixed at the front end of the handle, the blunt body is in a flat arc shape, the front end of the blunt body is bifurcated, and the inner edge and the outer edge are smooth. According to the retrobulbar optic nerve exposure device, retrobulbar optic nerves on the back face of an eyeball can be conveniently and safely detected, tissues around the optic nerves can be accurately and stably pushed aside to expose the optic nerves, and opening operation on an optic nerve sheath through an opening cutter in the following period can be conveniently carried out.

Description

A kind of ball optic nerve exposing device

Technical field

This utility model relates to medical instruments field, particularly a kind of for vagina nervi optici windowing special ball optic nerve exposing device.

Background technology

Because " intracranial Sagittal sinus thrombosis; cause intracranial hypertension " patient is because optic nerve is received compressing, cause eye imaging fuzzy, vision declines gradually, also be attended by headache, feeling of fullness in the head, tinnitus, successfully start clinically at present---vagina nervi optici windowing, has good therapeutic effect to this ophthalmic diseases.Vagina nervi optici windowing is passed through under the microscope, eye muscle is cut off, then outwards rotate eyeball, expose vagina nervi optici, on vagina nervi optici, cut one thin mouthful, to allow the cerebrospinal fluid of intracranial flow out along otch, reduce intracranial pressure, at utmost alleviate the compressing of high intracranial pressure to optic nerve, save patient's vision.In vagina nervi optici windowing, doctor needs hand nerve probe elevator middle part, with the head of nerve dissector, pushes the tissue around optic nerve aside, or the adhesion between separated optic nerve and soft tissue, and then with other instrument to vagina nervi optici opening.The common nerve dissector using is at present made by an elongated flat metal rod conventionally, yet, because eye socket working place is limited, simultaneously due to optic nerve sheath smooth surface, when using common nerve dissector to carry out separation, be difficult to push aside smoothly optic nerve tissue around, cause operating difficulties, operation Efficiency Decreasing, also easily produces nerve injury.

Utility model content

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of easy to operate, and security performance is high, for pushing the ball optic nerve exposing device of optic nerve surrounding tissue aside.

For achieving the above object, this utility model provides following technical scheme:

An optic nerve exposing device, comprises handle and the blunt body that is fixed on handle front end, and described blunt body is flat arc, blunt body front end jag, and outer edge is round and smooth.

In above-mentioned ball optic nerve exposing device, described handle is Anti-slip handle, is processed with anti-slip veins in handle surfaces.

This utility model comprises the blunt body of handle and handle front end, and handle is Anti-slip handle, has antiskid function.Blunt body is designed to through eyeball and eye socket gap, to stretch to the flat arc at eyeball rear according to base of principle of human engineering, blunt body front end jag, and outer edge is round and smooth, and between fork, internal diameter is a bit larger tham optic nerve diameter.When blunt body probes into eyeball rear, flat arcuate structure is conveniently detected optic nerve position, then optic nerve is snapped between two bifurcateds rapidly, appropriateness is pulled out backward, with separated optic nerve tissue around, optic nerve is come out, be convenient to follow-up vagina nervi optici be carried out to opening operation.

compared with prior art, the beneficial effects of the utility model:this utility model can be detected eyeball ball optic nerve below easily and safely, accurately firmly pushes optic nerve surrounding tissue aside, and optic nerve is come out, and is convenient to follow-up use incision knife vagina nervi optici is carried out to opening operation.
