Abstract
The invention relates to the field of medical instruments and particularly relates to a special optic-nerve-sheath incision knife for optic-nerve-sheath fenestration. The optic-nerve-sheath incision knife comprises a knife handle and a knife body, wherein a blocking piece is fixedly arranged at one side of the front end of the knife handle. The special optic-nerve-sheath incision knife has the advantages that since the blocking piece is fixed at one side of the front end of the knife handle, the tissue around the optic nerve can be isolated, the influence of the tissue around the optic nerve on a knife body in the incision process is avoided, so that the incision operation is carried out on the optic nerve sheath; the longer knife handle can be easy to extend into a narrow gap between the eyeball and the eyepit, so that the optic-nerve-sheath incision is accurately finished.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of for the vagina nervi optici windowing special vagina nervi optici incision knife.
Background technology
Because " intracranial Sagittal sinus thrombosis; cause intracranial hypertension " patient receives compressing owing to optic nerve, 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 at vagina nervi optici, in order to allow the cerebrospinal fluid of intracranial flow out along otch, Lowering the intracranial hypertension power, at utmost alleviate high intracranial pressure to the compressing of optic nerve, save patient's vision.In the vagina nervi optici windowing, the doctor needs hand nerve probe elevator middle part, pushes optic nerve tissue on every side aside with the head of nerve dissector, perhaps separates the adhesion between optic nerve and the soft tissue, and then with other instrument to the vagina nervi optici opening.
Present clinical operation generally adopts nerve to cut or neurotome carries out opening to nerve, but because optic nerve is positioned at the eyeball rear portion, and eyeball and orbit wall gap are very narrow, the nerve that structure is comparatively complicated is cut and is difficult to touch optic nerve; Simultaneously because optic nerve sheath smooth surface is assembled a large amount of tissues on every side, when using common refreshing incision knife to carry out opening, be difficult to accomplish in the opening process, not to be subjected to the impact of optic nerve surrounding tissue, cause operating difficulties, the operation Efficiency Decreasing also produces nerve injury easily.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art, a kind of practical vagina nervi optici incision knife is provided.
For achieving the above object, the invention provides following technical scheme:
The vagina nervi optici incision knife comprises handle of a knife, cutter hub, and a side of described handle of a knife front end is fixed with catch.
In the above-mentioned vagina nervi optici incision knife, described catch is circular.
In the above-mentioned vagina nervi optici incision knife, described handle of a knife middle part is provided with the arc-shaped groove that is distributed in distance.Can increase hand-held stability, prevent the incision knife landing.
In the above-mentioned vagina nervi optici incision knife, the length of described handle of a knife is 15～20cm.Long handle of a knife can probe into relatively easily the incision of eyeball rear and hold vagina nervi optici.
Compared with prior art, beneficial effect of the present invention:The fixing catch of handle of a knife front end one side of the present invention can be isolated the tissue around the optic nerve, avoids cutter hub to be subjected to the impact of optic nerve surrounding tissue in the opening process, so that vagina nervi optici is carried out the opening operation; Long handle of a knife can easily probe into narrow eyeball and eye socket gap, finishes exactly the vagina nervi optici opening.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that Fig. 1 is top view.
Fig. 3 is that Fig. 1 is upward view.
Labelling among the figure: 1-cutter hub, 2-handle of a knife, 3-groove, 4-rounded tabs.
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, present embodiment vagina nervi optici incision knife comprises that cutter hub 1, length are the handle of a knife 2 of 20cm, and described handle of a knife 2 middle parts are provided with the arc-shaped groove 3 that is distributed in distance, and the right side of described handle of a knife 2 front ends is fixed with rounded tabs 4.
During the vagina nervi optici windowing, expose first vagina nervi optici, with clamping forceps vagina nervi optici is provoked again, use at last the vagina nervi optici opening of vagina nervi optici incision knife to provoking of present embodiment.The tissue that the fixing catch 4 in handle of a knife 2 front end right sides can be isolated the right side avoids cutter hub 1 to be subjected to the impact of optic nerve surrounding tissue in the opening process, is convenient to vagina nervi optici is carried out the opening operation.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
Claims (4)
