Abstract

The utility model relates to a needle holder in eyes, comprising a sharp-nose part, a hand holding part and an automatic needle releasing spring clamping part. The structure of the utility model approximates to a pair of long thin sharp nose pliers with a bend head. The axle wires of the sharp-nose part and the hand holding part are provided with an included angle alpha. The needle holder in eyes of the utility model has the advantages that the needle is clamped stably, the operation is convenient, the operation time is shortened, the labor strength is reduced, and the success ratio of the operation is increased. The utility model is a very useful instrument for the operation in eyes.

Description

Needle holder in eye

A kind of ophthalmic needle holder belongs to medical apparatus, particularly a kind of intraocular surgery apparatus.The needle holder of present artificial intraocular lenses's implant surgery of adopting, the angle of sharp mouth and Handheld Division central axis are zero.This needle holder only is applicable to external coat, and seam corneosclera otch usefulness can not be carried out the ophthalmic operation.Because there are three shortcomings in it, this needle holder front end folder pin shakiness easily makes pin come off in ophthalmic; Most advanced and sophisticated folder pin can not make pin and needle holder direction be consistent, and can't operate within the eye; The needle holder front end is too short, and the rear end is too thick, stretch into ophthalmic after occupy-place big, can cause major injury eye inner tissue, when not having the ophthalmic needle holder, substitute the operation difficulty during intraocular surgery with minute hand, the postoperative reaction that is inflamed, have a strong impact on surgical consequences, for area retina shedding patient, with eye outer operation apparatus, operation is difficult for successfully, fixes and can improve success rate greatly as if there being the ophthalmic needle holder to make retina.

The purpose of this utility model is: for the artificial intraocular lenses implants and intraocular surgery provides a kind of easy to use, the apparatus of success rate of operation in improving greatly.Its technical scheme is: the ophthalmic needle holder is formed by connecting by sharp mouth, Handheld Division and automatic Folium Pini spring clamping section, feature of the present utility model is: ophthalmic needle holder structure proximate one has angle a to the elongated shape needle-nose pliers of band elbow between the axis of sharp mouth and Handheld Division two parts.

There is a hinge point mouth rear end, and rotate around the hinge different directions on sharp mouth both sides, forms Folium Pini or holds the pin operation.

Be with one on the Handheld Division and can move up and down tight loop, in the outside, handgrip front end both sides, both sides, Handheld Division the non-slipping block retaining is arranged, Folium Pini spring clamping section is installed on the medial surface on both sides, Handheld Division by spacing fixed block automatically; A angle size is between 15 °-25 °.

Fig. 1 is the side-looking structure chart of ophthalmic needle holder;

Fig. 2 overlooks Folium Pini status architecture sketch map for the ophthalmic needle holder;

Fig. 3 holds pin clamped condition structural representation for the ophthalmic needle holder.

Embodiment: Fig. 1,2,3 is the side-looking of ophthalmic needle holder, the plan structure sketch map.Wherein: (1) is sharp mouth, (2) turning joint, and (3) anti-skidding link stopper, (4) Handheld Division, (5) move up and down band, (7) spacing fixed block, (6) Folium Pini spring clamping section.

Enforcement of the present utility model is intraocular surgery, when particularly doing artificial crystal implant surgery, provides a kind of practical apparatus that improves success rate of operation greatly, can shorten operating time, alleviates doctor's labor intensity, improves curative effect.
