Abstract

A micro needle holder for ophthalmology comprises two tong arms with front ends hinged, clamping portions connected at the front ends of the tong arms and support elastic pieces at the back ends of the tong arms. The micro needle holder is characterized in that a snapping block is arranged on the inner side of one tong arm, a snapping groove with an arc stop piece bending towards the other tong arm at the edge is disposed on the inner side of the other tong arm, a gap capable of being passed by the snapping block is reserved between the stop piece and the other tong arm, grooves are positioned on the inner side of one clamping portion along the width direction, and anti-slip lines are arranged on the inner side of the other clamping portion. According to the micro needle holder, the two tong arms can be fastened through the snapping block and the snapping groove when the two tong arms are closed, and therefore knotting operations or cutting of sutures by scissors are facilitated for doctors; the grooves arranged on the inner side of one clamping portion can snap a suture needle and prevent jumping of a suture needle, and the anti-slip lines of the other clamping portion can prevent the suture needle from slipping. The micro needle holder is simple and reasonable in structural design, convenient to use, safe and reliable.

Description

A kind of ophthalmology microscopic needle holder

Technical field:

This utility model belongs to medical apparatus and instruments, is specifically related to a kind of ophthalmology microscopic needle holder.

Background technology:

In ophthalmologic operation, stitching of lacrimal ductule tissue etc. when usually needing to carry out cornea, iris, bulbar conjunctiva even ocular injury with microscopic needle holder, its way is to sew up for wound with the clamping part clip suture of microscopic needle holder, when cutting off stitching thread when sewing up knotting or after having sewed up, doctor's clamp handle of need holding with a firm grip prevents that sewing needle from coming off, must tie a knot simultaneously operates or with shears stitching thread is cut off, and its operation is difficulty.And because the sewing needle surface is more smooth, come off from clamping part easily, be not easy to doctor's operation.

Summary of the invention:

This utility model provides a kind of ophthalmology microscopic needle holder of being convenient to lock, prevent the sewing needle slippage for overcoming the deficiencies in the prior art.

The purpose of this utility model is achieved in the following ways: this ophthalmology microscopic needle holder, comprise two in the hinged clamp handle of front end, the suitable support shell fragment that connects of the suitable clamping part that connects of clamp handle front end and clamp handle rear end, it is characterized in that: the inboard of a described clamp handle is provided with fixture block, the front end of fixture block contacts with clamp handle, remainder bends parallel with clamp handle backward, and with clamp handle certain distance is arranged; The inboard of another clamp handle is provided with draw-in groove, and the edge of draw-in groove is provided with to the arc block plate of clamp handle bending, leaves between catch and the clamp handle and can hold the gap that fixture block passes through; The inboard that the inboard broad ways of a described clamping part is provided with groove, another clamping part is provided with anti-slip veins.

Preferably, the quantity of described groove is at least 2.

The beneficial effects of the utility model are: this ophthalmology microscopic needle holder, and when mediating, two clamp handles can two clamp handles locks by fixture block and draw-in groove, and facilitate like this doctor and tie a knot and operate or with shears stitching thread is cut off; The groove that the inboard of one of them clamping part is provided with can block sewing needle, prevents its play, and the anti-slip veins of another clamping part can prevent the sewing needle slippage.This utility model structural design advantages of simple, convenient to use, safe and reliable.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of the clamping part of this utility model band groove.

Fig. 3 is the structural representation of the clamping part of this utility model band anti-slip veins.

The specific embodiment:

With reference to each accompanying drawing, this ophthalmology microscopic needle holder, comprise two in the hinged clamp handle 1 of front end, the suitable support shell fragment 3 that connects of the suitable clamping part 2 that connects of clamp handle 1 front end and clamp handle 1 rear end, it is characterized in that: the inboard of a described clamp handle 1 is provided with fixture block 4, the front end of fixture block 4 contacts with clamp handle 1, remainder bends parallel with clamp handle 1 backward, and with clamp handle 1 certain distance is arranged; The inboard of another clamp handle 1 is provided with draw-in groove 5, and the edge of draw-in groove 5 is provided with to the arc block plate 8 of clamp handle 1 bending, leaves between catch 8 and the clamp handle 1 and can hold the gap that fixture block 5 passes through; The inboard broad ways that the inboard of a described clamping part 2 is provided with groove 6, another clamping part 2 is provided with anti-slip veins 7.The quantity of groove 6 is at least 2.

During use, mediate two clamp handles 1, and with clamping part 2 clip suture pins, sewing needle contacts with groove 6 on the clamping part 2, can prevent the sewing needle play like this, and the anti-slip veins on another clamping part 2 can prevent the sewing needle slippage.When needs are tied a knot to stitching thread or are cut off stitching thread, when mediating two clamp handles 1, allow fixture block 5 enter in the draw-in groove 5 by the gap between catch 8 and the clamp handle 1, the catch 8 of arc can block fixture block 5, prevent that itself and draw-in groove 5 break away from, so just make two clamp handles 1 keep the state of mediating, thereby be convenient to the knotting operation or cut off stitching thread.This specific embodiment is simple to operation, time saving and energy saving, safe and reliable.
