Abstract

The utility model discloses a multifunctional extraocular muscle hook, which comprises a hook body in fork-shaped structure; the fork-shaped hook body comprises a furcation I and a furcation II; pull hooks are respectively arranged at the front ends of the furcation I and the furcation II; and the tail parts of the furcation I and the furcation II are fixedly connected. The multifunctional extraocular muscle hook adopting the structure not only has all the functions of a strabismus hook, but also can simultaneously finish the task of pulling and uncovering the whitnall ligament, which requires two strabismus hook, so that an operator holding the strabismus hook can have one hand free to complete other tasks; in addition, the extraocular muscle hook can provide more operation space for operations and can be used more conveniently.

Description

Multi-functional extraocular muscles hook

Technical field

This utility model relates to medical instruments field, relates in particular to a kind of multi-functional extraocular muscles hook.

Background technology

At present, the extraocular muscles hook is a requisite specific purpose tool in the ophthalmologic operation.But the squint hook that employed extraocular muscles hook mostly is single hook in the prior art, when doing ophthalmologic operation, with a squint hook is the position that is difficult to accurately find and judge the muscle that is excised, size and shape, two handss of normal employing are respectively held a squint hook and are separated muscle together, accurately find the position of excision muscle, for little space operation as the ophthalmologic operation, two handss have occupied more operative space, be unfavorable for performing the operation and carry out smoothly, and for example separating the exposure extraocular muscles, when carrying out hook relieving accumulation of pathogens film and fascia tissue, also must respectively hold a squint hook by two handss and cooperate jointly and just can finish, such two squint hooks use cumbersome, and the operator who holds squint hook can not vacate hands and goes to finish other tasks.

Therefore, a kind of multi-functional extraocular muscles hook need be provided, the all functions that not only have a squint hook, can finish simultaneously needs two squint hooks tractive that just can finish and the task of exposing the restraining ligament, make the operator who holds squint hook can vacate a hands and go to finish other tasks, and, can be operation bigger working place is provided, use more convenient.

The utility model content

In view of this, this utility model provides a kind of multi-functional extraocular muscles hook, the all functions that not only have a squint hook, can finish simultaneously needs two squint hooks tractive that just can finish and the task of exposing the restraining ligament, make the operator who holds squint hook can vacate a hands and go to finish other tasks, and, can be operation bigger working place is provided, use more easily.

The multi-functional extraocular muscles hook that this utility model provides comprises the coupler body of fork configuration, and described fork-shaped coupler body comprises bifurcated I and bifurcated II, and the front end of described bifurcated I and bifurcated II is provided with drag hook respectively, and afterbody is fixedly connected.

Further, also comprise screw rod and adjusting nut, described screw rod one end is fixedly installed on the bifurcated II, the removable cooperation of the other end pass bifurcated I, adjusting nut is positioned at the bifurcated I outside and is spun on the screw rod;

Further, the front end of described drag hook is made flat structure;

Further, the hands handle of described bifurcated I and bifurcated II arranged outside side-friction stricture of vagina formation;

Further, the thickness of the handle of bifurcated I and bifurcated II and afterbody junction is less than the thickness of handle and afterbody;

Further, on the described screw rod back-moving spring is set, described back-moving spring two ends are respectively near bifurcated I and bifurcated II inboard.

The beneficial effects of the utility model are: a kind of multi-functional extraocular muscles hook that this utility model provides, the all functions that not only have a squint hook, can finish simultaneously needs two squint hooks tractive that just can finish and the task of exposing the restraining ligament, make the operator who holds squint hook can vacate a hands and go to finish other tasks, and, can be operation bigger working place is provided, use more convenient.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Accompanying drawing is a structural representation of the present utility model, as shown in the figure, multi-functional extraocular muscles hook comprises the coupler body of fork configuration, this fork-shaped coupler body comprises bifurcated I 1 and bifurcated II 2 again, the front end of bifurcated I 1 and bifurcated II 2 is provided with drag hook 3 respectively, the afterbody 4 of the afterbody of bifurcated I 1 and bifurcated II 2 is fixedlyed connected, and the coupler body of this kind structure has the function of two squint hooks.

7 settings of two handles of present embodiment comprise the governor motion of distance between scalable bifurcated I 1 that screw rod 5, adjusting nut 6 formed and the bifurcated II 2, screw rod 5 one ends are fixedly installed on the bifurcated II 2, the removable cooperation of the other end pass bifurcated I 1, adjusting nut 6 is positioned at bifurcated I 1 outside and is spun on the screw rod 5, can adjust distance between two hooks by adjusting nut 6; On the screw rod 5 of present embodiment back-moving spring 8 is set, back-moving spring 8 two ends are respectively near the inboard of two handles 7, and after two drag hooks 3 were compressed, under the effect of back-moving spring 8, two drag hooks 3 can automatically reset.

The front end of the drag hook 3 of present embodiment is made flat structure, when hook relieving accumulation of pathogens film and fascia tissue, can prevent that tissue or muscle break away from from drag hook 3.

The handle 7 that the bifurcated I 1 of present embodiment and bifurcated II 2 arranged outside side-friction stricture of vaginas form, the friction stricture of vagina of holding in use on the handle 7 helps holding tight handle 7, avoids landing from hands.

The thickness of the bifurcated I 1 of present embodiment and the handle of bifurcated II 27 and afterbody 4 junctions is less than the thickness of handle 7 and afterbody 4, closed fully or open when reaching maximum at drag hook 3, because handle 7 has fabulous elasticity with afterbody 4 junctions, can not cause the fixed connection place fracture of afterbody 4.

During use, adjusting nut 6, two drag hooks 3 that screw on the screw rod 5 are closed fully, and can be used as a squint hook and use this moment, has all functions of a squint hook, comprises tractive muscle, fascia, conjunctiva etc.; When the adjusting nut 6 that unscrews on the screw rod 5, two drag hooks, 3 open width can be transferred to 20 millimeters from 0 millimeter, can be used as two squint hooks and use this moment, two drag hooks 3 are stretched into respectively under the fascia of muscle both sides, parallel with muscle and along its traveling tractive backward, can finish the task of abundant exposure restraining ligament; Two drag hooks 3 are stretched under the muscle, drag hook 3 is vertical with muscle, by the width of adjusting nut 6 adjustings two drag hooks, can reach the muscle length of accurate labelling excision, the width of two drag hooks 3 is measured with strabismus ruler or rule, can reach the function of the muscle length of accurate labelling excision; Because this multi-functional extraocular muscles hitcher has two drag hooks 3, in the orthpia operation, the operator can respectively hold squint hook tractive by two handss and assist to finish operation and become one hand-held one multi-functional extraocular muscles hook assistance finished operation, go to finish other tasks and vacate a hands, also can be operation bigger working place is provided, and, use more convenient.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
