Abstract
The utility model discloses a vitrectomy corneal contact lens fixator which is characterized by being formed by a lens frame, movable metal rings, a movable joint and a movable handle. The lens frame is in round design, the edge of a frame body starts to be provided with a sliding groove, the two movable metal rings are arranged in the sliding groove, the positions of the metal rings can be adjusted according to actual requirements, a mounting base is arranged below the lens frame, the movable joint is connected with the mounting base through a spindle and formed by an angle regulator and a handle mounting base, the handle mounting base is arranged below the angle regulator, and the movable handle is connected to the lower portion of the handle mounting base through threads. The vitrectomy corneal contact lens fixator is reasonable in design, compact in structure and simple to operate, saves operation time, and not only is suitable for ordinary vitrectomy, but also is specially designed for corneal limbal cut vitreous body operations.
Description
Technical field
This utility model relates to a back segment Vitrectomy equipment technical field, is specifically related to a kind of Vitrectomy corneal contact lens holder.
Background technology
The indication expanding day of vitrectomy, range of operation almost spreads all over whole eyeball except cornea, sclera.Particularly, its indication is divided into anterior chamber of eye, eye back segment indication; And in posterior vitreous cutting and periphery or the cutting of vitreous body base portion, must application corneal contact lens.Conventional corneal contact lens has two types: 1. hand-held lens; Generally by assistant, operated.2. floated lens; The becket of corneal contact lens is sewed up and is fixed on limbus of corneae both sides, and the lens of different model are placed in picture frame, by assistant, are arbitrarily changed.
Vitrectomy apparatus used and type of goods are very various, in posterior vitreous cutting, must lay corneal contact lens or floated lens rectification eye refraction, the clear intraocular surgery of being engaged in of ability, the corneal contact lens using at present need to be sewed up fixing mostly, operating time is long, damage is large, after-operation response weight, and recovery time is long.
Utility model content
The deficiency existing for prior art, it is a kind of simple in structure, easy to operate that this utility model provides, and can save the Vitrectomy corneal contact lens holder of operating time and simplification operative procedure, is specially adapted to the operation on vitreous of particularity case.
For achieving the above object, this practicality provides a kind of Vitrectomy corneal contact lens holder, and this utility model adopts following technical scheme: Vitrectomy corneal contact lens holder; It is characterized in that being formed by: picture frame (1), live metal ring (2), movable joint (3) and flexible handle (4); Described picture frame (1) is circular design, and on framework edge, starting has chute, is provided with two live metal rings (2) in chute, can regulate according to actual needs becket position; In described picture frame (1) below, be provided with mount pad (5); Described movable joint (3) is connected with mount pad (5) by axle (6); Described movable joint (3) consists of angle demodulator (7) and handle mount pad (8); Described handle mount pad (8) is located at angle demodulator (7) below; Described flexible handle (4) is threaded connection in handle mount pad (8) below.
Advantage of the present utility model: 1, this utility model is reasonable in design, compact conformation, easy to use.
2, this utility model adopts loose collar and fixed handle design, and fixedly contact lens, can shorten operating time, and minimizing patient's misery, can also reduce postoperative complication, to specific type operation on vitreous as through the special practicality of cut-out of limbus corneae operation on vitreous.
3, this corneal contact lens holder has designed two loose collars and a handle, does not need to sew up to fix, and is particularly useful for corneal distortion, the rear fixedly posterior vitrectomy of stitching of becket of operation on vitreous otch change.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Symbol description in figure: picture frame 1, live metal ring 2, movable joint 3, flexible handle 4, mount pad 5, axle 6, angle demodulator 7, handle mount pad 8.
The specific embodiment
With best embodiment, this utility model is described in detail below.
As shown in Figure 1, vitrectomy corneal contact lens holder; It is characterized in that being formed by: picture frame (1), live metal ring (2), movable joint (3) and flexible handle (4); Described picture frame (1) is circular design, and on framework edge, starting has chute, is provided with two live metal rings (2) in chute, can regulate according to actual needs becket position; In described picture frame (1) below, be provided with mount pad (5); Described movable joint (3) is connected with mount pad (5) by axle (6); Described movable joint (3) consists of angle demodulator (7) and handle mount pad (8); Described handle mount pad (8) is located at angle demodulator (7) below; Described flexible handle (4) is threaded connection in handle mount pad (8) below; During use, assistant can utilize handle fixing metal ring, thereby fixing contact lens keeps in touch mirror and is positioned at cornea face when not sewing up becket.
Finally it should be noted that: obviously, above-described embodiment is only for this utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
