Description

Novel forceps for clamping loose conjunctiva

Technical Field

The utility model belongs to the technical field of tweezers, concretely relates to press from both sides new-type tweezers of getting lax conjunctiva.

Background

The human eyeball is a sphere, which is divided into cornea and sclera. Wherein, the surface of the sclera is covered by a vascular membrane, which is called as a conjunctiva medically, and the conjunctiva is clung to the sclera under normal conditions. With the age, especially for the middle aged and the elderly, the conjunctiva is subject to the symptoms of loose elasticity caused by the decrease of elasticity, foreign body sensation, lacrimation, dry eyes and the like. The clinical treatment for the disease is as follows: the incision is closed by conventional surgery or by cutting excess, loose conjunctival tissue using a high frequency electric knife and suturing or cauterizing.

In excising the flaccid conjunctival tissue, a two-person procedure is required if the flaccid conjunctival tissue is to be excised relatively accurately: after local anesthesia, one person holds and lifts the flaccid conjunctival tissue with forceps, and the other person cuts the flaccid conjunctival tissue along the edges of the forceps with scissors or a high-frequency electric knife, and finally closes the incision by suturing or cauterizing. The following disadvantages exist in this process: the face of the traditional forceps for clamping the conjunctival tissue is relatively smooth, and the traditional forceps are very easy to slip when clamping the conjunctival tissue, so that the operation development is influenced. In addition, many conventional forceps are not self-closing, so that a person is required to separately manipulate the forceps to hold the flabby conjunctival tissue during the operation.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel forceps for clamping the flabby conjunctiva, which can prevent the flabby conjunctiva from slipping through arranging an anti-slip part, thereby facilitating the smooth development of the operation; in addition, the elastic buckle, the limiting bulge and the locking hole can play a role in auxiliary positioning, and the operation can be performed by a single person conveniently.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a novel forceps for grasping a flaccid conjunctiva, comprising:

a forceps handle;

the connecting arms are symmetrically arranged at one end of the forceps handle at intervals;

the forceps arms are symmetrically arranged on the 2 connecting arms at intervals, an elastic buckle is fixed on the inner wall of each forceps arm, and the front end of each elastic buckle inclines upwards; the tail end of the front end of the elastic buckle is also integrally formed with a limiting bulge; the second forceps arm is provided with a locking hole corresponding to the limiting bulge;

the other ends of the first forceps arm and the second forceps arm are respectively and integrally formed with a forceps head, and 2 anti-skidding parts are arranged on the inner walls of the forceps heads.

Preferably, the forceps handle is flat.

Preferably, the anti-slip part is a sawtooth-shaped protrusion, and the sawtooth-shaped protrusions on 2 forceps heads are mutually meshed.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses a tweezers are overhead to be equipped with the antiskid portion of mutually supporting, and lax conjunctiva can tightly be held to antiskid portion, prevents its slippage, is convenient for develop smoothly of operation.

(2) The utility model discloses have elasticity to detain and the locking hole on tweezers arm to set up the spacing arch that corresponds with the locking hole on elasticity is detained, at the actual operation in-process, when 2 tweezers arms of extrusion, elasticity is detained spacing arch and is passed the locking hole and block in the outside in locking hole, can play the assistance-localization real-time effect like this, the one-man operation of the operation of being convenient for.

Detailed Description

In the following, the technical solutions of the present invention are described clearly and completely, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the technical personnel in the field without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-2, a novel forceps for grasping a flaccid conjunctiva comprises:

a flat forceps handle 100;

connecting arms 200 symmetrically arranged at one end of the forceps handle 100 at intervals;

the first forceps arm 300 and the second forceps arm 400 are symmetrically arranged on the 2 connecting arms 200 at intervals, an elastic button 500 is fixed on the middle part of the inner wall of the first forceps arm 300, and the front end of the elastic button 500 inclines upwards; the front end of the elastic button 500 is integrally formed with a limit protrusion 501; a locking hole 401 corresponding to the limiting bulge 501 is formed in the second forceps arm 400;

the other ends of the first forceps arm 300 and the second forceps arm 400 are respectively integrally formed with a forceps head 600, the inner walls of the 2 forceps heads 600 are respectively provided with an anti-slip portion 601, specifically, the anti-slip portions 601 are saw-tooth-shaped protrusions, and the saw-tooth-shaped protrusions on the 2 forceps heads 600 are mutually meshed.

When the forceps handle is used, an operator holds the forceps handle 100 with one hand and squeezes the first forceps arm 300 and the second forceps arm 400 to clamp and lift loose conjunctival tissues, in the process of squeezing the first forceps arm 300 and the second forceps arm 400, the limiting protrusions 501 of the elastic buckle 500 enter the locking holes 401, meanwhile, the front ends of the elastic buckle 500 deform, after the limiting protrusions 501 penetrate through the locking holes 401, the limiting protrusions 501 are clamped outside the locking holes 401, and meanwhile, the anti-sliding portions 601 on the inner walls of the 2 forceps heads 600 are matched with each other to clamp the loose conjunctiva tightly. When the first forceps arm 300 and the second forceps arm 400 are no longer squeezed, the limiting protrusion 501 cannot retract from the locking hole 401, so that the 2 forceps heads 600 can be prevented from being away from each other, and the flaccid conjunctiva can be clamped. The other hand of the operator operates scissors or a high-frequency electric knife to cut off the loose conjunctival tissue along the edge of the forceps, and finally the incision is closed by suturing or cauterizing. After use, the limiting protrusion 501 is pushed to be disengaged from the locking hole 401. From the above, the single-person operation of the operation can be realized by using the forceps in the present embodiment.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
