Abstract
The utility model discloses a pair of tweezers, which comprises two mutually symmetrical tweezer arms, wherein tweezer handles are integrally formed at one ends of the tweezer arms, the other ends of the tweezer arms separately form free ends, the free ends comprise handheld parts and clamping parts, clamp heads of the clamping parts of the free ends are made to present crescent moon shapes or spoon shapes, a plurality of round holes are formed in the handheld parts of the free ends, pin posts are arranged at the inner sides of the handheld parts of the free ends, and the clamping parts of the free ends are in a linear shape or a bent shape. The tweezers have the advantages that the structure is simple, the cost is low, and in addition, the use in the intraocular lens operation is convenient.
Description
Technical field
This utility model relates to a kind of tweezers, particularly a kind of tweezers for artificial intraocular lenses's operation.
Background technology
Artificial intraocular lenses is a kind of artificial lenses, and for replace nature crystal when the natural crystal of eyes suffers from cataract and other diseases, the artificial intraocular lenses who is made by soft material can implant ophthalmic by a less otch after folding or curling.In employing injector, carry out in the process of artificial intraocular lenses's implant surgery, artificial intraocular lenses is being preloaded onto while injecting in front and need to stretching in pipeline front button loop is stretching, current main stretching mode is for putting in a little hook from injecting a front end in advance, hook front button loop, be pre-installed after artificial intraocular lenses, little hook is pulled out, when pulling out, front button loop is stretching and bring pipeline into, this kind of operational approach relative complex, needs more step and instrument, if use tweezers will simplify its operation.And in prior art for the tweezers of ophthalmologic operation, its structure is applicable to certain specific purposes more, a kind of tweezers for phacoemulsification cataract surgery continuous curvilinear capsulotomy as described in the application number patent " a kind of Wicresoft Tweezers for eye surgery " that is 200720069729.X, by hands handle, press hands, adapter sleeve, cervical region and tweezer head form, cervical region is elongated, can pass through little otch, the similar scoop of sheet under tweezer head, with sharp blade, can flipping, it is central to wear front capsule, and the gripping cyst membrane edge that directly makes progress with upper slice, it is easy and simple to handle, wound is little, do not hide surgical field of view, capsulorhexis success rate is high.The clamping part of common tweezers mostly is most advanced and sophisticated or flat end, tweezers as described in the application number patent " a kind of forceps " that is 200820226542.0 comprise two tweezer tablets, the rear end of two tweezer tablets is fixedly connected with, front end ovalize, be applicable to clamp absorbent cotton etc., make medical personnel when clamping absorbent cotton wiping wound, can not injure wound because of tip, have advantages of safe and reliable.Above tweezers are all unsuitable for using in artificial intraocular lenses's operation.
Utility model content
Problem to be solved in the utility model is to provide a kind of simple in structure, with low cost and tweezers of being convenient to use in artificial intraocular lenses operation.
To achieve these goals, this utility model adopts following technical scheme:
, comprise two symmetrical tweezer arms, described Nie Bei one end one-body molded formation tweezer handle, other end interval forms free end, and described free end comprises Handheld Division and clamping part, and the chuck of described free end clamping part is set to crescent shape or spoon shape;
On described free-ended Handheld Division, be provided with several circular holes;
Inner side, described free-ended Handheld Division is provided with pin;
Described free-ended clamping part is linear or bent.
Beneficial effect:
Adopt the tweezers of such scheme, owing to being provided with circular hole on described free end, so make on the one hand the position that these tweezers in use can fixed finger, have anti-skidding effect, can alleviate on the other hand the weight of tweezer body, convenient use, reduces costs.Owing to being provided with pin on described tweezers, stroke that can restraint of liberty end, prevents firmly excessively, causes distortion.Because described free-ended clamping part is straight shape or bent and chuck place is arranged to crescent shape or spoon shape, be more convenient for artificial intraocular lenses to push and inject pipeline.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model tweezers.
Fig. 2 is the structural representation of this utility model embodiment 1 tweezers that provide.
Fig. 3 is the structural representation of this utility model embodiment 2 tweezers that provide.
In figure: 1, tweezer handle, 2, free end, 3, Handheld Division, 4, clamping part, 5, pin, 6, chuck, 7, circular hole, 8, linear clamping part, 9, bending clamping part, 10, crescent shape chuck, 11, spoon shape chuck.
The specific embodiment
As shown in Figure 2, a kind of tweezers, comprise two symmetrical tweezer arms, described Nie Bei one end one-body molded formation tweezer handle, and other end interval forms free end, and described free end comprises Handheld Division and clamping part, and the chuck of described free end clamping part is set to crescent shape;
On described free-ended Handheld Division, be provided with 3 circular holes;
The inner side of described free-ended Handheld Division is provided with 2 pins;
Described free-ended clamping part is linear.
This utility model is simple in structure, convenient and practical, can form a meniscate little hook by clamping two free ends of tweezers, hooks three-chip type artificial intraocular lenses's front button loop, is pushed and injects in pipeline, simultaneously that it is straight.
As shown in Figure 3, a kind of tweezers, comprise two symmetrical tweezer arms, described Nie Bei one end one-body molded formation tweezer handle, and other end interval forms free end, and described free end comprises Handheld Division and clamping part, and the chuck of described free end clamping part is set to spoon shape;
On described free-ended Handheld Division, be provided with 3 circular holes;
The inner side of described free-ended Handheld Division is provided with 2 pins;
Described free-ended clamping part is bending.
This utility model is simple in structure, convenient and practical, and clamping part is set to bending, and chuck and hands no longer, on same straight line, avoid hands in use procedure to block sight line, are particularly useful in the middle of medical operating.The chuck of the spoon shape gripping profile of being more convenient for is circular-arc object.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content in description, must determine technical scope according to claim scope.
