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
The present invention relates to medical instruments field, particularly a kind of for the vagina nervi optici windowing special ball optic nerve exposing device.
Background technology
" intracranial Sagittal sinus thrombosis; cause intracranial hypertension " patient is because optic nerve is received compressing for cause, cause eye imaging fuzzy, vision descends gradually, also be attended by headache, feeling of fullness in the head, tinnitus, successfully start clinically at present---the vagina nervi optici windowing has good therapeutic effect to this ophthalmic diseases.The vagina nervi optici windowing is passed through at microscopically, eye muscle is cut off, then outwards rotate eyeball, expose vagina nervi optici, cut one thin mouthful on vagina nervi optici,, in order 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 the vagina nervi optici windowing, the doctor needs hand nerve probe elevator middle part, with the head of nerve dissector, pushes optic nerve tissue on every side aside, perhaps separates the adhesion between optic nerve and soft tissue, and then with other instrument to the vagina nervi optici opening.The common nerve dissector that uses is at present made by an elongated flat metal rod usually, yet, because the eye socket working place is limited, simultaneously due to optic nerve sheath smooth surface, when using common nerve dissector to separate, be difficult to push aside smoothly optic nerve tissue on every side, cause operating difficulties, the operation Efficiency Decreasing, also easily produce nerve injury.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art, provide a kind of easy to operate, security performance is high, is used for pushing aside the ball optic nerve exposing device of optic nerve surrounding tissue.
For achieving the above object, the invention provides following technical scheme:
Ball optic nerve exposing device, comprise handle and the blunt body that is fixed on the 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 on handle surfaces.
The present invention includes the blunt body of handle and handle front end, handle is Anti-slip handle, has antiskid function.Blunt body is designed to and can stretches to the flat arc at eyeball rear through eyeball and eye socket gap 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 the optic nerve diameter.When blunt body probeed into the eyeball rear, flat arcuate structure was conveniently detected the optic nerve position, then optic nerve was snapped between two bifurcateds rapidly, appropriateness is pulled out backward, to separate the tissue around optic nerve, optic nerve is come out, be convenient to follow-up vagina nervi optici be carried out the opening operation.
Compared with prior art, beneficial effect of the present invention:The present invention can detect the ball optic nerve of eyeball back easily and safely, accurately firmly pushes the 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 the opening operation.

Labelling in figure: 1-Anti-slip handle, 2-blunt body, 3-jag.
The specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
, in order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the ball optic nerve exposing device of the present embodiment, comprise Anti-slip handle 1 and the blunt body 2 that is fixed on Anti-slip handle 1 front end, and described blunt body is flat arc, blunt body front end jag 3, and outer edge is round and smooth.
The foregoing is only preferred embodiment of the present invention,, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
