Abstract
The utility model relates to an eyeball enucleation tool. The eyeball enucleation tool comprises a scissors body. The two ends of the scissors body are provided with scissors handles and a scissors opening respectively, wherein opening and closing of the scissors opening are controlled by the scissors handles. The eyeball enucleation tool is characterized by further comprises a sliding sheet; the sliding sheet comprises a front sheet and a rear sheet; an obtuse included angle is formed between the front sheet and the rear sheet; an open groove is formed in the end of the front sheet; a kidney-shaped groove is formed in the middle of the sliding sheet; the part where the front sheet and the rear sheet are combined is located within the length range defined by the kidney-shaped groove; when the sliding sheet is located at the initial position, the front sheet of the sliding sheet is attached to the scissors body, and an included angle alpha is formed between the rear sheet of the sliding sheet and the scissors body; when the sliding sheet moves to the working position, an included angle alpha is formed between the front sheet of the sliding sheet and the scissors body, and the rear sheet of the sliding sheet is attached to the scissors body. After the eyeball enucleation tool is adopted, during eyeball enucleation, an eyeball can be lifted by a certain distance and optic nerve s are exposed as long as the sliding sheet on the scissors body is pushed, the optic nerve behind the eyeball can be cut off through the scissors body, and the situation that eyeball enucleation is not thorough due to the fact that the optic nerve is not cut off while the rear end of the eyeball is cut broken is avoided.
Description
Technical field
This utility model relates to a kind of eyeball excise operation tool, for extracing operation on eyeball, belongs to technical field of medical instruments.
Background technology
While carrying out clinically eyeball excise operation, committed step is to cut off retrobulbar optic nerve, and the eyeball that is connected with a bit of optic nerve is taken out in eye socket.Optic nerve be after eyeball (optic disc) to a cord structures of intracranial, while cutting off optic nerve, left hand-held apparatus is outwards mentioned eyeball, the right hand is pressed optic nerve scissors backward, object is to wipe out a part of retrobulbar optic nerve more as far as possible, especially the patient of malignant tumor, the longer the better for the optic nerve of excision, in order to avoid stump of optic nerve has malignant tumor tissue residual.While carrying out this operation clinically, need the eyeball tissue of extracing conventionally to go to pot, make eyeball be difficult to mention, therefore in practical operation, often occur that the optic nerve part of extracing together with eyeball is too short, even optic nerve is not cut and posterior pole of eyeball is broken, and causes operation not thorough.
Summary of the invention
The purpose of this utility model is to provide a kind of instrument that is exclusively used in eyeball excise operation.
In order to achieve the above object, the technical solution of the utility model has been to provide a kind of eyeball excise operation tool, comprise scissor body, the two ends of scissor body are respectively shear shank and by shear shank, are controlled the shears mouth of folding, it is characterized in that: also comprise slide plate, slide plate comprises anter and rear panel, between anter and rear panel, be an obtuse angle angle, the end of anter is formed with the groove of an opening, at the middle part of slide plate, be provided with waist type groove, the junction of anter and rear panel is positioned at the length range that waist type groove limits, the pin joint place of scissor body is outward extended with axle, axle embeds in waist type groove, slide plate can move by axle and waist type groove between initial bit and working position, when slide plate is positioned at initial bit, the anter of slide plate and scissor body laminating, between the rear panel of slide plate and scissor body, be an angle α, when slide plate moves to working position, between the anter of slide plate and scissor body, be an angle α, the rear panel of slide plate and scissor body laminating.
Preferably, described axle embeds after described waist type groove, at the top of axle, screws in and has nut, at nut and outer shaft sleeve, has spring, at axle, is also arranged with pad outward, and the two ends of spring offset with top and the pad of nut respectively.
Preferably, described angle α is 15 degree-30 degree.
Adopt after this utility model, in eyeball excise operation, promote the slide plate on shears, can make eyeball lift one end distance, expose optic nerve, shears just can be cut off one section of optic nerve after eyeball, avoid optic nerve not cut and posterior pole of eyeball is broken, causing operation not thorough.
Accompanying drawing explanation
The top view of a kind of eyeball excise operation tool that Fig. 1 provides for this utility model;
A kind of eyeball excise operation tool that Fig. 2 provides for this utility model is cut into the schematic diagram of eyeball;
A kind of eyeball excise operation tool that Fig. 3 provides for this utility model lifts the schematic diagram of eyeball;
The mounting structure enlarged drawing of a kind of eyeball excise operation tool slide plate that Fig. 4 provides for this utility model.
The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
In conjunction with Fig. 1 to Fig. 4, a kind of eyeball excise operation tool that this utility model provides, comprises scissor body, and the two ends of scissor body are respectively shear shank 4 and by shear shank 4, are controlled the shears mouth 1 of folding.Also comprise slide plate 2, slide plate 2 comprises anter and rear panel, is an obtuse angle angle between anter and rear panel, and the end of anter is formed with the groove 5 of an opening, at the middle part of slide plate 2, be provided with waist type groove 3, the junction of anter and rear panel is positioned at the length range that waist type groove 3 limits.The pin joint place of scissor body is outward extended with axle 8, axle 8 embeds in waist type groove 3, at the top of axle 8, screws in and has nut 11, at nut 11 and axle 8 overcoats, has spring 10, outside axle 8, be also arranged with pad 9, the two ends of spring 10 offset with top and the pad 9 of nut 11 respectively.Slide plate 2 can move by axle 8 and waist type groove 3 between initial bit and working position, when slide plate 2 is positioned at initial bit, the anter of slide plate 2 and scissor body laminating, between the rear panel of slide plate 2 and scissor body, be an angle α, when slide plate 2 moves to working position, between the anter of slide plate 2 and scissor body, be an angle α, the rear panel of slide plate 2 and scissor body laminating, angle α is 15 degree-30 degree.
During use, as Fig. 1 state, shears mouth 1 and slide plate 2 extend into after eyeball, promoting slide plate 2 makes the open slot 5 on slide plate 2 embed optic nerve 7 (as Fig. 2), due to the two-stage nitration of slide plate 2 not in one plane, while promoting slide plate 2, open slot 5 ends on slide plate 2 can lift (as Fig. 3) by eyeball 6, now operate shear shank 4, shears mouth 1 is cut off optic nerve 7.
