Abstract
The utility model relates to the technical field of medical equipment, in particular to implanting forceps for implanting an intraocular lens into an eyeball in a clinical eyeball surgery. The implanting forceps comprise handle extension portions, handle portions, connection portions and clamping tips, and are characterized in that the handle extension portions are elastic handles, the handle portions are provided with slim grains, the connection portions are hinged and can be opened or closed by axially centering a crossing point of the connection portions, clamping portions are in arc shapes similar to physiological structures of human eyes, the tips of the clamping portions are oblate. The intraocular lens implanting forceps is convenient to use, friction force is enlarged by the aid of the slim grains on the handle portions so that instruments can be prevented from slipping during surgery, surgical safety is improved, surgical time is shortened, operating efficiency is improved, pain of patients is relieved, and possibility of surgical complications is decreased.
Description
Technical field
This utility model relates to technical field of medical instruments, a kind ofly specifically is used for clinical operation on eyeball, and the artificial intraocular lenses is implanted implantation tweezer in it.
Background technology
Present domestic eyes cataract operation is after corneosclera is finished tunnel incision outside, the artificial intraocular lenses to be clamped with tweezers, become with eyes from the top 90 ° (with vertical cube to), insert in the crystal capsule bag from incision.During operation, a hands is clamped conjunctiva with tweezers, and the another hands stretches into crystal with crystal positioning hook marginal position corneal incision from the eyeball both sides, stirs crystal gently, make it by the rotation of original deviation position or move to appointed positions, be exposed at the outer crystal of capsule and all enter in the capsule.But this implantation tweezer has the following disadvantages:
(1) the handle portion bit strip has circular hole, makes that hand-held frictional force is little, very easily comes off in operation is carried out, and has strengthened operation and has carried out difficulty.
(2) handle position poor flexibility adopts special steel alloy to be made because existing artificial intraocular lenses implants tweezer, and elasticity is bigger.Yet as the tweezers of ophthalmologic operation, its elasticity requires higher, makes the tweezers feel from hard to soft, to reduce the pressure damage of tweezers to the artificial intraocular lenses.
(3) tip shape is adopted in the end, very easily causes the back capsule to break.Although the end has been carried out Passivation Treatment in use, in operation, still there is very big danger.
Summary of the invention
The purpose of this utility model promptly produces thus, has proposed a kind of artificial intraocular lenses who makes operation have characteristics such as convenient, accurate, that damage is little and has implanted tweezer.
The technical scheme that its technical problem that solves this utility model adopts is: the artificial intraocular lenses implants tweezer, comprise handle extending part, handle position, connecting portion, retaining part, retaining part foremost, it is characterized in that: described handle extension is an elastomeric grip, there is stria at described handle position, described connecting portion is that twisting connects, and be axle center expansible or merging with its merge point, the arc of described retaining part is near human eye's physiological structure, and retaining part is oblate foremost.
This utility model artificial intraocular lenses implants tweezer and compares with existing medical apparatus and instruments, has following outstanding beneficial effect: easy to use, improved operation safety, shortened operating time, improve work efficiency, alleviated patient's misery, reduced the possibility that causes postoperative complication.
Description of drawings
Fig. 1 is that the artificial intraocular lenses implants tweezer contour structures sketch map;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 be on Fig. 1 retaining part A to enlarged drawing;
1 handle extending part among the figure, 2 handle positions, 3 connecting portions, 4 retaining parts, 5 retaining parts are foremost.
The specific embodiment
With reference to Figure of description 1-Fig. 3 artificial intraocular lenses of the present utility model is implanted tweezer and do following detailed explanation.
Artificial intraocular lenses of the present utility model implants tweezer, its structure comprises handle extending part 1, handle position 2, connecting portion 3, retaining part 4, retaining part foremost 5, it is characterized in that: described handle extension 1 is elastomeric grip, described handle position 2 strias, described connecting portion 3 connects for twisting, and be axle center expansible or merging with its merge point, the arc of described retaining part 4 is near human eye's physiological structure, and retaining part 5 is oblate foremost.
When carrying out artificial intraocular lenses's implant surgery, the artificial intraocular lenses to be implanted tweezer with the artificial intraocular lenses clamp, handle extending part 1 feel has been reduced crystalline accidental injury by cirrhosis elasticity, has protected the safety of back capsule, has reduced the damage of corneal endothelium; There is the stria that increases frictional force at handle position 2, carries out middle instrument landing to prevent operation, has improved the ongoing safety of operation; Retaining part 4 its arc under closed fully state is convenient to doctor's operation technique more near the human physiological structure; Retaining part is 5 oblate structure foremost, has reduced the disruptive danger of back capsule, has reduced the generation of postoperative complication.
Claims (1)
1. the artificial intraocular lenses implants tweezer, comprise handle extending part (1), handle position (2), connecting portion (3), retaining part (4), retaining part (5) foremost, it is characterized in that: described handle extension (1) is elastomeric grip, there is stria at described handle position (2), described connecting portion (3) connects for twisting, and be axle center expansible or merging with its merge point, the arc of described retaining part (4) is near human eye's physiological structure, and retaining part (5) foremost is oblate.
