Abstract
The utility model belongs to the technical field of ophthalmic surgeries and particularly relates to a retina tweezers and optical fibers integrated device which is used in vitrectomy united retina proliferative membrane decollement. The retina tweezers and optical fibers integrated device comprises a handle and a pair of retina tweezers which is arranged at the top at the front end of the handle; optical fibers are arranged on the upper portion at the front end of the handle; a power line is arranged on the tail portion of the optical fibers; the power line is connected with a power source. The retina tweezers and optical fibers integrated device has the advantages of being simple in structure and convenient to operate and effectively avoiding iatrogenic retina tearing and entering into sclera channel incisions for a plurality of times.
Description
Technical field
This utility model belongs to ophthalmologic operation technical field, is specifically related to a kind of retina tweezer and optical fibers integrated device using in combined vitrectomy retina propagation film decollement.
Background technology
Film decollement is an important ingredient in operation on vitreous, due to the existence of preretinal membrane cause retina fixedly fold form, make the stiff fixedly inertia of retina.Preretinal membrane causes funnel shaped detachment of retina in various degree widely, affects reattachment of retina, therefore must carry out film decollement, the clean level that film is peeled off is directly relevant with surgical effect.In practical operation because the position of human body eye is narrow and small, and in operation, the intensity of light and bright range bring great inconvenience to not medical personnel in operation technique, easily there is the iatrogenic retina of tearing, cause retinal hole and hemorrhage, or there is repeatedly entering sclera access incisions, cause pigmented film to come off and tongue tear, closed not good situation.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, and provides a kind of simple in structure, easy and simple to handle, can effectively avoid iatrogenic retina tweezer and the optical fibers integrated device of tearing retina and repeatedly entering sclera access incisions situation.
The purpose of this utility model is achieved in that the retina tweezer that comprises handle and be located at handle front top, and wherein, handle upper front end is provided with optical fibers, and optical fibers afterbody is provided with power line, and power line is connected with power supply.Described handle front end offers power line import, handle tail end offers power line outlet, power line import and power line outlet are connected by the cavity of handle inside, and power line is successively by power line import, and the cavity of handle and power line outlet are connected with power supply.Described fiber-optic length is greater than the length of retina tweezer.Described fiber-optic width is not more than the diameter of handle front end.Described fiber-optic width is 2mm.
The utlity model has simple in structure, easy and simple to handlely, can effectively avoid the iatrogenic advantage of tearing retina and repeatedly entering sclera access incisions situation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, 2, this utility model comprises handle 1 and the retina tweezer 2 that is located at handle 1 front top, and wherein, handle 1 upper front end is provided with optical fibers 3, and optical fibers 3 afterbodys are provided with power line 4, and power line 4 is connected with power supply.Described handle 1 front end offers power line import 5, handle 1 tail end offers power line outlet 6, power line import 5 and power line outlet 6 cavitys 7 by handle 1 inside are connected, and power line 4 is successively by power line import 5, and the cavity 7 of handle 1 and power line outlet 6 are connected with power supply.The length of described optical fibers 3 is greater than the length of retina tweezer 2.The width of described optical fibers 3 is not more than the diameter of handle 1 front end.The width of described optical fibers 3 is 2mm.
The length that the length of optical fibers 3 of the present utility model is greater than retina tweezer 2 can guarantee that the light in operation process has enough intensity and bright range, the diameter that the width of optical fibers 3 is not more than handle 1 front end can guarantee, in medical personnel's practical operation, not affect the enforcement of operation.In operation process, optical fibers 3 is switched on power and can be performed the operation, in the situation that guaranteeing that operation can be implemented smoothly, can effectively avoid the iatrogenic retina of tearing, cause retinal hole and hemorrhage, or occur repeatedly entering sclera access incisions, cause pigmented film to come off and tongue tear, closed not good situation occurs.
