Abstract

The utility model discloses a cornea rust ring scissors, comprising a handle, a joint part and a beak part, wherein the front end of the joint part forms an angle of 135 degrees with the surface of the handle, and the front part of the side scissors beak of the beak part forms an angle of 135 degrees with the joint part, consequently the front part of the side scissors beak is parallel to the surface of the handle, thereby the discommodity that ill cornea can not be wiped off effectively by using appliances of prior technique is solved, and the damaged area wiping off normal cornea in operation are reduced.

Description

Cornea rust ring is cut

This utility model relates to the cornea rust ring that is used for the cornea surgery and cuts.

In the cornea surgical operation, run into corneal foreign body rust ring through regular meeting and reject,, corneal ulcer is struck off, this class operation of the reparation of cornea break-through wound, the apparatus of implementing above-mentioned operation mainly is foreign body needle or cutter and uses common eye with cutting.Existing common eye because the handle of cutting and angle and two mis-arranges of cutting beak of beak portion bring difficulty for patient's clinical manipulation, therefore, wishes to have a kind of being more suitable for to cut in the cornea rust ring of clinical use with cutting.

The purpose of this utility model is to provide a kind of cornea rust ring that can overcome the prior art defective to cut.

Cut according to cornea of the present utility model rust ring and to comprise a crooked resilient handle of both sides camber, in other words, form by the flexure strip of two direction bendings opposite each other.The one end links to each other with beak portion by the joint, and the other end is one and has a protuberance that another has the groove of admitting described protuberance, so that form ring-type.A joint that connects handle and beak portion, the joint is made up of two braces, described two braces connect into " X " shape structure by rivet, the same end and the handle of described two braces are affixed, and the other end extends forward and up or down and becomes 135 ° angle with plane, handle place.A beak portion, beak portion cuts beak by two sides that are connected with the brace of connecting portion respectively and forms, two sides are cut beak and are identical falcate downward or upward, falcate downward or upward and joint partly are 135 °, thus, it is consistent with handle angle that the falcate shearing partly is in, in other words, if handle is in level, falcate is sheared and partly is in level equally.

Cornea rust ring of the present utility model is cut with respect to its advantage of prior art and is, and the first, the shearing of handle and beak portion partly is on two faces that are parallel to each other, and therefore, it helps clinical use.Second, because the joint is 135 ° and beak portion up or down with respect to handle and the joint is 135 ° downward or upward, the left side is cut be positioned at joint below or right side to be cut and be positioned at the below, joint, thereby solved prior art and only be suitable for an orientation, and the defective that disease is decreased cornea can't be effectively wiped out in another orientation, prevents maloperation.The 3rd, from clinical result of use, reduced the damaged area of normal cornea widely, wound is smooth.

Above-mentioned purpose of the present utility model and other purpose and advantage thereof will be more readily apparent from by the detailed description below in conjunction with the accompanying drawing illustrated embodiment, and accompanying drawing has:

Fig. 1 is the sketch map of cutting according to cornea rust ring of the present utility model;

Fig. 2 A and Fig. 2 B are the sketch maps that joint component is amplified;

Fig. 3 A and Fig. 3 B are the sketch maps that beak portion amplifies.

With reference to accompanying drawing, an embodiment who cuts according to cornea rust ring of the present utility model has been shown among Fig. 1, it comprises that 1, one beak portion 3 of a handle is connected the joint part 2 of handle 1 and beak portion 3 with one.Wherein, handle is made up of the flexure strip 11 and 12 of camber.The end of one end of flexure strip 11 has one to protrude part 13, and the end of another flexure strip 12 has one can admit flexure strip 11 to protrude partly 13 groove 14.When the other end of two flexure strips 11,12 and below that the joint part 2 of explanation is affixed, flexure strip 11,12 forms the elastic flexible handle of tool.The hole 15 that has a receivability operator finger on each flexure strip at least is so that the operator is hand-held and the application of force.In the inboard of flexure strip 11 ridge 16 is arranged, this ridge is used to prevent the excessive application of force, plays the link stopper effect.Described joint partly 2 is made up of two braces 21 and 22.Two

braces

21 and 22 fuse by pin 23, but and the end of two flexure strips 11 of an end of

relative motion brace

21 and 22 and handle 1 and 12 affixed.The

brace

21 and 22 the other end extend upward (Fig. 2 A) or extend (Fig. 2 B) downwards after extending a distance forward, no matter be to extend up or down, and the angle of it and handle 1 is 135 °.Described beak portion 3 cuts beak 31 and 32 by two sides and forms, two sides are cut an end of beak and joint, and partly an end of two braces 11,12 of 2 is affixed, its shape is identical curved month type, and with joint partly 2 two

braces

21 and 22 one-tenth 135 ° angle (Fig. 3 A and 3B).But still downward direction bending extension makes progress, this is decided by brace 21 and the 22 front ends angle with respect to handle, if extend upward (Fig. 2 A), then two sides are cut beak and are bent downwardly, cut beak 31 and 32 and be in the state that parallels with handle 1 to guarantee side, the left side is cut be positioned at the below, joint, be suitable for cutting the cornea of top.If extend downwards (Fig. 2 B), then two sides are cut beak and are bent upwards, and to guarantee that cutting beak 31 and 32 is in the state that parallels with handle 1, the right side is cut be positioned at the top, joint, are suitable for the cornea of the side of cutting.

Cut according to cornea of the present utility model rust ring and generally to use the titanium alloy manufacturing, also can be with other suitable material, example is the medical stainless steel manufacturing.

The applicant is described in detail design of the present utility model and embodiment; the professional and technical personnel can make various conversion and improvement on this basis; but these conversion and improvement all do not break away from spirit of the present utility model, all within the protection domain that claims limit.
