Abstract

Provided is an optic nerve combining and dividing device applied in eyeball enucleation operations. At present, the commonly used optic nerve cutting instruments used in a clinic are curved scissors. Because the scissors are lack of dexterity, the operations usually come to deadlock. The optic nerve combining and dividing device comprises a cross optic nerve eyeball supporting frame and an optic nerve hook knife. The heads of the cross optic nerve eyeball supporting frame and the optic nerve hook knife are both in flat arc shapes, the tips of the cross optic nerve eyeball supporting frame and the optic nerve hook knife are in circular smooth hook shapes, and the hook directions are the same. The outer edge of the cross optic nerve eyeball supporting frame and the optic nerve hook knife are smooth, and the tips of the cross optic nerve eyeball supporting frame and the optic nerve hook knife are adducent. The difference between the cross optic nerve eyeball supporting frame and the optic nerve hook knife lies in that the inner edge of the cross optic nerve eyeball supporting frame is blunt while the inner edge of a hook of the optic nerve hook knife is sharp. When the cross optic nerve eyeball supporting frame is inserted into the rear sides of the eyeballs and contacted with the optic nerves, the optic nerves can be quickly and accurately hooked. By means of a support effect of an instrument on the eyeballs, the rear gaps of the eyeballs are widened, and the optic nerves are clamped tightly and simultaneously. The optic nerve hook knife is utilized to extend in the rear portion of the eyeball from the other side at this time to hook the optic nerves in the opposite direction. A method similar to 'reaping with a sickle' is utilized to divide the optic nerves quickly, thereby being safe and convenient to operate.

Description

Optic nerve associating cutter

Affiliated technical field

This utility model is a kind of main apparatus of using in the eyeball excise operation of ophthalmology critical illness People's Bank of China.

Background technology

The eyeball excise operation is for the patient who suffers from serious eye pathological changes, for preventing further expanding of its pathological changes, or be the misery that reduces the patient, and eyeball surrounding tissue (comprising optic nerve, extraocular muscles etc.) is cut off, the modus operandi of the complete excision of eyeball of having lost visual function or profile.Optic nerve is the important step of this operation from breaking, and quick, accurate, complete is the successful essential condition of operation from disconnected optic nerve.At present, optic nerve is shears from the disconnected main apparatus that uses, but the gap is very narrow between eyeball and the orbit wall, and optic nerve is comparatively tough and tensile again, the dynamics deficiency so small-sized shears is easy to stretch into, and large-scale shears dynamics is suitable but detect difficulty after stretching into ball.In addition, because optic nerve sheath smooth surface, can not hold preferably optic nerve and from disconnected of shears tends to cause the predicament of " detect-cut-optic nerve break away from shears-detect-cut ".What is more important in eyeball in the treating malignant tumor, should be wiped out one section optic nerve as much as possible and prevent cancer diffusion and recurrence, if lack the fixing optic nerve of the pull strength of eyeball necessity, can't enlarge optic nerve and wipe out scope.These situations can increase the generation of patient's slight illness and complication undoubtedly, thereby cause the harmful effect to patient's life and health.

Summary of the invention

In order to reduce the misery that eyeball excise is performed the operation and brought to the patient, quick, accurate, complete from disconnected optic nerve, this utility model provides a kind of optic nerve associating cutter of practicality easy and simple to handle.

The technical scheme that its technical problem that solves this utility model adopts is: constitute the associating cutter by striding two apparatuses of optic nerve eyeball carriage and optic nerve plastic cutter.For being fit to the apparatus migration in eyeball and eye socket gap, both heads adopt flat arc design, and the head tip is slick and sly hook-type, both hook direction unanimities, the outer rim slyness is received in the tip, the damage normal surrounding tissue can more firmly collude and pull optic nerve simultaneously when preventing to use.The two difference is to stride the design of optic nerve eyeball carriage inner edge passivity, and optic nerve plastic cutter inner edge is a sharp sword.During use, probe into after the eyeball rear touches optic nerve when striding optic nerve eyeball carriage, can quickly and accurately it be caught on, utilize apparatus that lifting with draw of eyeball widened retrobulbar gap, firmly block simultaneously optic nerve, use the optic nerve plastic cutter to stretch into the eyeball rear from opposite side this moment, catches on optic nerve with opposite direction, the mode of utilizing similar " reaping hook harvesting " rapidly with optic nerve from disconnected, the sheared length of optic nerve can be regulated according to the Therapeutic Principle of various disease.

The beneficial effects of the utility model are: can more easily probe into narrow eyeball and eye socket gap, accurately, catch on optic nerve securely, safely, promptly finish optic nerve then from disconnected, so both avoided shears behind ball, to detect repeatedly and repeatedly from disconnected accidental injury to surrounding tissue, it is operational loaded down with trivial details also to have reduced operator, reaches the purpose of safe and convenient.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is a positive design drawing of the present utility model, by striding optic nerve eyeball carriage (1.) and two apparatuses of optic nerve plastic cutter (2.) are formed, both constitute by Handheld Division and head, the head tip is slick and sly hook-type, both hook direction unanimities, the outer rim slyness is received in the tip, the difference of them part is that the hook inner edge of striding optic nerve eyeball carriage designs for passivity, and optic nerve plastic cutter hook inner edge is a sharp sword.

Fig. 2 is lateral layout figure of the present utility model, and the Handheld Division of striding optic nerve eyeball carriage (1.) and two apparatuses of optic nerve plastic cutter (2.) is flat design, and head all adopts flat arc design.

The specific embodiment

Outer rim slyness in Fig. 1 strides the most advanced and sophisticated hook portion of optic nerve eyeball carriage in is 1. drawn optic nerve in order to collude; 2. optic nerve plastic cutter hook portion inner edge is sharp, in order to from disconnected optic nerve.Left hand is held and is striden optic nerve eyeball carriage during enforcement, probe into and rapidly it is caught on after optic nerve is touched at the eyeball rear, the Tilly is widened retro-ocular space with apparatus to the effect of lifting of eyeball on the appropriateness, firmly block simultaneously optic nerve, this moment, the right hand used the optic nerve plastic cutter to stretch into the eyeball rear from opposite side, caught on optic nerve with opposite direction.Both oppositely exert oneself, and stride optic nerve eyeball carriage when stablizing optic nerve, the optic nerve plastic cutter in the mode of similar " reaping hook harvesting " rapidly with optic nerve from disconnected.The sheared length of optic nerve can be regulated according to the Therapeutic Principle of various disease.

Claims (1)

1. the optic nerve associating cutter of application during an eyeball excise is performed the operation, it is characterized in that: comprise and stride optic nerve eyeball carriage and optic nerve plastic cutter two parts, both heads are flat arc, the tip is slick and sly hook-type, both hook direction unanimities, the outer rim slyness is received in the tip, it is passivity that the two difference is to stride optic nerve eyeball carriage inner edge, and optic nerve plastic cutter inner edge is a sharp sword.
