Abstract
The utility model discloses a multi-purpose nucleus fragmenting/taking and lens implanting integrated tweezer, which belongs to the field of medical instruments. The tweezer is composed of two tweezer pieces, and the two tweezer pieces are connected through a rotating shaft and can be opened or closed. The integrated tweezer comprises a handheld part, a neck part and a clamping part, wherein the clamping part is arranged at the front end of the neck part, and the handheld part is fixedly connected with the neck part; the axial bend of the neck part facing the rotating shaft is arc-shaped; and the clamping part is oblate, and the diameter of the clamping part is 0.5-0.8 mm. The tweezer disclosed by the utility model has the advantage that the surgical operation can be performed conveniently and rapidly, and the post-operation discomfortableness of patients also can be reduced.
Description
Technical field
This utility model relates to medical instruments field, refers to especially a kind of multipurpose fragmentation nucleus, gets core, crystal implants the one tweezer.
Background technology
At present, when carrying out non-phacoemulsification, often needing multiple operating theater instruments jointly to coordinate just can complete.Need cataract nucleus crushing device during fragmentation nucleus, need crystal circle spoon while getting core, crystal need to be used and implant tweezer or implantation device while implanting, and so just makes operation technique not easy, and operating time is longer.In addition, while using crystal circle spoon or existing implantation tweezer, need larger otch just can be operated, after just causing perform the operation, the patient can produce astigmatism, and is not easy to heal after too large due to otch.
The utility model content
The utility model proposes a kind of multipurpose fragmentation nucleus, get core, crystal implants the one tweezer, can carry out quickly and easily operation technique, and can reach and alleviate uncomfortable purpose after the sufferer operation.
The technical solution of the utility model is achieved in that a kind of multipurpose fragmentation nucleus, gets core, crystal is implanted the one tweezer, and described one tweezer consists of two monolithic tweezers, and its two monolithics tweezers are by turning cylinder connection and expansible or merging; Described one tweezer comprises Handheld Division, cervical region and is positioned at the clamping part of cervical region front end, and described Handheld Division and cervical region are connected; Described cervical region is curved towards the axial bending of described turning cylinder; It is oblate that described clamping part is, and its diameter is 0.5～0.8mm.
Further, be provided with elastomeric grip in the extension of described Handheld Division.
Further, described Handheld Division and cervical region are one-body molded.
Further, the radian of described cervical region and human eye's physiological structure is complementary.
Further, the diameter of described clamping part is 0.6mm.
Further, the outside of described Handheld Division offers antiskid thread.
Further, described one tweezer is made by titanium alloy.
The beneficial effects of the utility model are: (1) adopts above-mentioned tweezers, can carry out quickly and easily operation technique, and the operating time required time is short, and can alleviate the rear discomfort of sufferer operation; (2) adopt above-mentioned tweezers, when being performed the operation, required otch≤3.5mm just can be operated, thereby has reduced corneal Endothelium, iris and cyst membrane damage; (3) adopt above-mentioned tweezers, I-VI level core can be split into to 2-3mm in pouch, thereby conveniently core is taken out; (4) adopt above-mentioned tweezers, can be for clamping the artificial intraocular lenses and being implanted; (5) these tweezers are through clinical verification, safe and reliable, easy and simple to handle effective, only need to use these tweezers just can replace traditional cataract nucleus crushing device, get the apparatuses such as core tweezer and crystal circle spoon.
The accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only one of them embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The front view that Fig. 1 is this utility model embodiment;
The top view that Fig. 2 is this utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only one of them embodiment of the present utility model, rather than whole embodiment.Embodiment based in this utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of this utility model protection.
As depicted in figs. 1 and 2, a kind of multipurpose fragmentation nucleus, get core, crystal and implant the one tweezer, consist of two monolithic tweezers, its two monolithics tweezers are by turning cylinder 5 connections and expansible or merging; The one tweezer comprises Handheld Division 2, cervical region 3 and is positioned at the clamping part 4 of cervical region 3 front ends, and Handheld Division 2 is connected with cervical region 3; Cervical region 3 is curved towards the axial bending of turning cylinder 5, for making cervical region 3 in the situation that less otch enter in pouch and operated smoothly; It is oblate that clamping part 4 is, and its diameter is 0.5～0.8mm, is can well carry out fragmentation nucleus, get core and crystal is implanted for Convenient tweezers.
In this utility model embodiment, be provided with elastomeric grip 1 in the extension of Handheld Division 2, can reduce the accidental injury to eye, improve the safety of operation.Handheld Division 2 is one-body molded with cervical region 3.The radian of cervical region 3 and human eye's physiological structure are complementary, and facilitate cervical region 3 to enter in pouch and are operated.The diameter of clamping part 4 is 0.6mm.The outside of Handheld Division 2 offers antiskid thread.The one tweezer is made by titanium alloy.In use, corneosclera completes the otch of 3.5mm outside, from incision, by the cervical region of one tweezer 3, be inserted into gently in pouch, use clamping part 4 that nucleus is caught broken to the size into 2-3mm, then the nucleus be caught broken is taken out one by one from incision, finally clamp the artificial intraocular lenses and be implanted in capsule, and be adjusted to desired location.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
