AI Technical Summary
During the removal of existing ophthalmic conjunctival stones, it is difficult to remove the conjunctival stones and easily damage the surrounding normal tissue.
A tweezer including a handle, a first tweezer leg and a second tweezer leg is designed. The first tweezer leg and the second tweezer leg are respectively formed with a tweezer head. The conjunctiva is pierced through the knife tip at the head end of the second tweezer leg, so that the conjunctiva is located in the spoon at the head end of the first tweezer leg, and then the tweezers are brought together by pinching the conjunctiva stones, and the conjunctiva stones are removed through the retraction process.
The forceps can effectively prevent stones from slipping, reduce damage to surrounding normal tissues, and achieve accurate and rapid removal of conjunctival stones.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of ophthalmic medical instruments, and particularly relates to a pair of forceps for removing ophthalmic conjunctival stones. Background Art
[0002] Conjunctival stones are common diseases in the ophthalmology clinic. At present, the removal of conjunctival stones almost entirely relies on a 1 ml syringe. By using the tip of the needle of the 1 ml syringe to pierce the conjunctival tissue beside the stone, and then carefully peeling out the stone through the needle of the 1 ml syringe, and then carefully removing it outside the eye. The operation process is extremely inconvenient. Especially when removing the stone, it often slips off, and it is very easy to damage the normal conjunctival tissue. At present, there are relevant patents for stone-removing instruments, but they are also inconvenient to use, and there are no related products on the market. Summary of the Utility Model
[0003] The main purpose of the utility model is to provide a pair of forceps for removing ophthalmic conjunctival stones, aiming to solve the problems of difficult removal of conjunctival stones and easy damage to the surrounding normal tissues during the removal of existing ophthalmic conjunctival stones.
[0004] To achieve the above purpose, the technical solution proposed by the utility model is: a pair of forceps for removing ophthalmic conjunctival stones, characterized in that it includes a handle, a first forceps leg, and a second forceps leg; the tails of the first forceps leg and the second forceps leg are fixedly connected to form a forceps handle; a first forceps head is formed at the head of the first forceps leg; a second forceps head is formed at the head of the second forceps leg; the first forceps head and the second forceps head face each other; both the first forceps leg and the second forceps leg are arc-shaped, and the first forceps leg and the second forceps leg are bent relatively. Anti-slip patterns are provided on the outer surfaces of the first forceps leg and the second forceps leg. The head of the first forceps leg is an elliptical perforated ring. The head of the second forceps leg is a solid spoon shape, and there is a sharp knife tip at the end. The first forceps leg, the second forceps leg, and the handle are all made of stainless steel.
[0005] Compared with the prior art, the utility model at least has the following beneficial effects: The pair of forceps for removing ophthalmic conjunctival stones proposed by the utility model can prevent the phenomenon of difficult fixation and slipping of the stone during the removal of conjunctival stones, as well as the phenomenon of damage to the surrounding normal tissues and conjunctival bleeding caused by repeatedly piercing the conjunctiva. Specifically, the forceps for removing conjunctival stones pierce the conjunctiva through the knife tip at the head end of the second forceps leg, so that the conjunctiva is located in the spoon at the head end of the first forceps leg. Then, by squeezing, the ends of the first forceps leg and the second forceps leg are brought together, and the ring at the end of the first forceps leg presses on the conjunctival stone, and the conjunctival stone is removed from the conjunctiva during the retraction of the forceps. Doctors can operate more precisely and quickly when using the forceps for removing conjunctival stones of the present utility model. Description of the Drawings
