Abstract

The cataract capsulorhexis needle solves the problem that a main incision of cataract is larger due to the fact that no appropriate minimally invasive tool is available in the annular capsulorhexis process in the existing cataract surgery, and comprises a tip part, a body part and a connecting part, wherein the tip part, the body part and the connecting part form a Z-shaped structure, the connecting part is arc-shaped and smooth, and the body part is detachably connected with a handle; the right end of the body part is fixed with a conical disc, the left end of the conical disc is smaller than the right end of the body part, the left end of the handle is fixed with a conical body, the left end of the conical body is smaller than the right end of the handle, and the conical disc and the conical body are matched to form the body part which is detachably connected with the handle.

Description

Cataract capsulorhexis needle

Technical Field

The utility model relates to the technical field of surgical instruments for cataract surgery, in particular to a cataract capsulorhexis needle.

Background

All the reasons such as aging, heredity, local nutrition disorder, immunity and metabolism abnormality, trauma, poisoning, radiation and the like can cause the metabolic disorder of crystalline lens, so that the protein of the crystalline lens is denatured to generate opacity, which is called cataract, at the moment, light rays are blocked by the opacity crystalline lens and can not be projected on retina, so that the vision is blurred.

One step of cataract surgery is annular capsulorhexis, which can be carried out by a minimally invasive method, and the capsulorhexis forceps need a large incision and easily cause unnecessary injury to patients.

SUMMERY OF THE UTILITY MODEL

Aiming at the situation, the utility model provides a cataract capsulorhexis needle which effectively solves the problem that the capsular rhexis wound is large because no proper tool is available in the annular capsulorhexis process in the prior cataract surgery.

In order to solve the problems, the utility model comprises a tip part, a body part and a connecting part, wherein the tip part, the body part and the connecting part form a Z-shaped structure, the connecting part is arc-shaped and smooth, and the body part is detachably connected with a handle; the right end of the body part is fixed with a conical disc, the left end of the conical disc is smaller than the right end of the body part, the left end of the handle is fixed with a conical body, the left end of the conical body is smaller than the right end of the handle, and the conical disc and the conical body are matched to form the body part which is detachably connected with the handle.

Preferably, the tip portion is fixedly connected with the connecting portion, and the angle between the tip portion and the connecting portion is 90 °.

Preferably, the connecting part is fixedly connected with the body part, and the connecting part and the body part are arranged at an angle of 120 degrees.

The utility model discloses a mode of wicresoft is operated the patient, greatly reduces the area of wound, reduces the complication, and point portion is perpendicular with connecting portion, and point portion is sharp needle point, is convenient for puncture the cyst membrane.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a schematic diagram of the side-axis structure of the present invention.

Fig. 3 is an enlarged schematic view of a portion a in fig. 1.

Detailed Description

The following description will be made in detail with reference to the accompanying fig. 1-3.

As shown in figures 1-3, the utility model comprises a tip part 1, a body part 2 and a connecting part 3, wherein the tip part 1, the body part 2 and the connecting part 3 form a Z-shaped structure.

The point part 1, the body part 2 and the connecting part 3 can be made by adopting a disposable needle head, and the disposable needle head is bent to form a Z-shaped structure, so that the capsulorhexis needle can capsulorhexis the cataract through a minimally invasive opening, and the size of the incision is reduced.

The tip part 1 is fixedly connected with the connecting part 3, and a 90-degree angle is formed between the tip part 1 and the connecting part 3.

The needle folding position of the tip part 1 is positioned at the center of the needle point, and the tip part 1 is vertical to the connecting part 3, so that the needle can be conveniently placed.

The connecting part 3 is fixedly connected with the body part 2, and 120 degrees are formed between the connecting part 3 and the body part 2.

The needle folding position of the body part 2 is 3mm away from the root of the needle head.

Further comprises a handle 4, wherein the handle 4 is detachably connected with the body part 2.

The point part 1, the body part 2 and the connecting part 3 are of an integrated structure, the connecting part is arc-shaped and smooth, and the connecting part and the handle 4 are positioned on the same horizontal plane, so that the operation is convenient.

2 right-hand member of somatic part is fixed with

conical disk

5, and 5 left ends of conical disk are less than the right-hand member, and 4 left ends of handle are fixed with

conical body

6, and 6 left ends of conical body are less than the right-hand member, and conical disk 5 constitutes somatic part 2 with the cooperation of conical body 6 and can dismantle with handle 4 and be connected.

The handle 4 is a reusable handle, and the body 2 is connected with the handle 4 through the matching of the conical disc 5 and the conical body 6, and the handle 4 can adopt a common syringe.

For better effect, the handle 4 can be set into a structure capable of adjusting the length, and the structure capable of connecting the telescopic mop used in the family can be used for adjusting the length of the handle 4.

The utility model discloses when using, through holding handle 4 with the finger, will point portion 1, connecting portion 3 get into patient's eye through little wound to tear the bag operation to the patient, can effectually avoid relevant operation complication, just the utility model discloses can adopt ordinary syringe needle to make, practice thrift the cost in the very big degree, also can directly carry out batch production with this device in addition, thereby avoid influencing the operation effect because of holding to make inexperiencedly.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
