Abstract

It the utility model is related to a kind of artificial lens dedicated scissors.Mainly include：Left and right to be hinged, described left and right includes cutter head, handle and spring leaf, and the cutter head is the tulwar head bent to scissors folding direction, and the point of a knife of cutter head is 1/4 circle, and the point of a knife of left and right cutter head merges composition semicircle.This dedicated scissors is used to intraocular lens being cut into fragment, is easy in the case of smaller otch, by intraocular lens removal, can greatly shorten operating time, reduces the incidence of complication, improves surgical effect and recovers beneficial to patient.

Description

A kind of artificial lens dedicated scissors

Technical field

Technical field of medical instruments is the utility model is related to, it is specifically a kind of to be used in Clinical Ophthalmology operation, by people Work crystal be cut into two halves or several pieces, the convenient artificial lens dedicated scissors taken out from intraocular.

Background technology

In clinic, cataract is the major reason for causing the elderly to blind.The essential therapeutic arsenals of cataract are hand at present Art, specific modus operandi are implanted into transparent artificial lens and replaced to extract muddy cataract.Current application is most widely Folded iol, deploy after being put into from smaller otch.In clinic in some cases, again need take out or more When changing artificial lens, but taking out artificial lens, artificial lens can not be folded again, so the otch needed is larger, easily made Into postoperative complication.Therefore, it is necessary to which artificial lens is cut into two halves or more fragment using surgical scissors, it is easy in smaller otch In the case of, by intraocular lens removal, to shorten operating time, the incidence of complication is reduced, improves surgical effect.

The similar surgical scissors of selection can be used for there are 2 kinds and respectively have deficiency in clinical at present：

（1）Common Ophthalimic microsurgery is cut, and its shortcoming is that apparatus is thicker, it is necessary to which larger cuts when operating within the eye Mouthful, and because scissors bit is the eye inner tissue such as tip, easy corneal damage endothelium, iris.

（2）The cyst membrane of ophthalmic is cut, and its shortcoming is the excessively very thin weakness of apparatus, and intensity is insufficient, it is difficult to cuts artificial lens Open.

Therefore, it is those skilled in the art's skill urgently to be resolved hurrily to design a kind of artificial lens dedicated scissors for meeting clinical demand Art problem.

In the prior art, the report of such artificial lens dedicated scissors is not found.

The content of the invention

The present invention is in order to solve the above problems, it is proposed that a kind of artificial lens dedicated scissors, for intraocular lens to be cut Into two or more fragment, is easy in the case of smaller otch, by intraocular lens removal；Operating time can be greatly shortened, The incidence of complication is reduced, improves surgical effect, the eye inner tissue such as corneal damage endothelium, iris in operation is prevented and is beneficial to suffer from Person recovers.

To achieve these goals, the present invention adopts the following technical scheme that：

A kind of artificial lens dedicated scissors, including：

Left and right connected by articulated mounting, described left and right includes cutter head, handle and spring leaf；Institute State cutter head be to scissors folding direction bend tulwar head, and the point of a knife of cutter head be 1/4 circle arc, the point of a knife of right cutter head with The point of a knife of left cutter head merges composition semicircle.Preferably, non-slip texture and loss of weight through hole are provided with the handle.

Preferably, the handle inwall is provided with locating part.

Preferably, the one end of described two spring leafs away from handle is respectively equipped with bayonet socket and the fastener to match with bayonet socket.

Preferably, the dedicated scissors are martensitic stain less steel using material.

Preferably, the spring leaf uses adjustable connected mode with handle.

Preferably, the cutter head length is 6 ~ 10mm.

Preferably, the decreased food is 11 ~ 12mm.

Preferably, the cutter head length is 8mm.

Beneficial effects of the present invention are：

（1）The tulwar head bent to scissors folding direction, not only improves and probes into operative site, also help in cutting process In fix artificial lens, it is easy to operation.

（2）The point of a knife of cutter head is 1/4 circle, and the point of a knife of left and right cutter head merges composition semicircle；Can so in surgical procedure Reduce the damage risk of the eye inner tissues such as scissors cutter head corneal Endothelium, iris.

Fig. 2 is Fig. 1 schematic top plan view；

Fig. 3 is Fig. 1 scissors cutter heads position A to enlarged diagram；

In figure：1st, spring leaf, 2, handle, 3, articulated mounting, 4, right cutter head, 5, left cutter head.

Embodiment：

The invention is described further with embodiment below in conjunction with the accompanying drawings.

A kind of artificial lens dedicated scissors, its structure as shown in Figure 1, Figure 2, Figure 3 shows, including：

Left and right connected by articulated mounting 3, described left and right includes cutter head, handle 2 and spring leaf 1；The cutter head is the tulwar head bent to scissors folding direction, and the point of a knife of cutter head is the arc of 1/4 circle, right cutter head 4 Point of a knife merges composition semicircle with the point of a knife of left cutter head 5.

Non-slip texture and loss of weight through hole are provided with the handle.

The handle inwall is provided with locating part.

The one end of described two spring leafs away from handle is respectively equipped with bayonet socket and the fastener to match with bayonet socket.

The dedicated scissors are martensitic stain less steel and surface passivation using material.

The application method of this dedicated scissors is as follows:

1. artificial lens dedicated scissors are stretched into eyeball from eye cut；

2. the artificial lens that needs are cut is included between the artificial lens dedicated scissors cutter head of opening；

3. clutching handle, artificial lens is cut；

4. release handle, artificial lens dedicated scissors cutter head is opened, sheared next time；

5. all handle is clutched, artificial lens dedicated scissors are exited from eye cut after the completion of shearing.

The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality Type.A variety of modifications to embodiment will be apparent for those skilled in the art, as defined herein General Principle can in other embodiments be realized, do not give in the case where not departing from spirit or scope of the present utility model Describe the part presented with partial enlargement in detail, be prior art, herein without repeating.Therefore, the utility model will not Embodiment illustrated herein is restricted to, and is to fit to the most wide model consistent with principles disclosed herein and feature Enclose.
