Abstract

The present invention relates to a needle instrument for an eye-bag relocating operation. The needle instrument includes a body unit having a rectangular cross-section and grabbed by a needle holder during the operation; a needle unit having one needle side and the other needle side on both sides of the body unit to be tapered and having round tips, wherein one needle side is formed to be duller than the other needle side; and a thread pressing and coupling unit provided on one end of the body unit and formed at a position that corresponds to ⅕ to ⅙ of an entire length from an end of the needle instrument and is spaced apart from the end of the body unit by 0.5 to 1 mm.

Claims

1. A needle instrument for an eye-bag relocating operation, which is used to fix an eye bag relocated at a lower position in a lacrimal groove during the eye-bag relocating operation and has an arc shape, the needle instrument comprising:

a body having a rectangular cross-section, and configured to be grabbed by a needle holder during the operation, the body including a first end and a second end;

a first needle side and a second needle side respectively connected to the first end and the second end of the body, the first and second needle sides being tapered, and including round tips, wherein the first needle side tip is duller than the second needle side tip; and

a thread pressing and coupling portion provided on the first end of the body, and disposed at a position that corresponds to ⅕

to ⅙

of an entire length from an end of the first needle tip and is spaced apart from the first end of the body by 0.5 to 1 mm, wherein, a through hole is disposed through the thread pressing and coupling portion and configured to be connected to a thread, and the first and second ends of the body are configured to be pressed by a press machine to attach the thread thereto.

2. The needle instrument of claim 1, wherein the body has a rounded edge.

3. A method of relocating the eye-bag using the needle instrument of claim 1, wherein, in a state where the needle instrument is inserted down through an incised conjunctiva inside an eye and the needle instrument is connected with the eye bag using the thread, after the second needle passes through skin tissue of the lacrimal groove to be exposed to an outside, the needle instrument is moved or rotated and the needle instrument is pulled out from the skin tissue starting from the first needle, so that the thread is caught in the skin tissue and a part of the eye bag is pulled downwards to be relocated in the lacrimal groove, and then the thread is knotted, so that the relocated eye bag is fixed by the thread caught in the skin tissue.

4. A needle instrument for an eye-bag relocating operation, which is used to fix an eye bag relocated at a lower position in a lacrimal groove during the eye-bag relocating operation and has an arc shape, the needle instrument comprising:

a body having a rectangular cross-section, and configured to be grabbed by a needle holder during the operation, the body including a first end and a second end;

a first needle side and a second needle side respectively connected to the first and second ends of the body, the first and second needle sides being tapered, wherein the first needle side comprises a round tip and the second needle side comprises a tip that is cut in a triangular shape; and

a thread pressing and coupling portion provided on the first end of the body, and disposed at a position that corresponds to ⅕

to ⅙

of an entire length from an end of the first needle tip and is spaced apart from the first end of the body by 0.5 to 1 mm, wherein, a through hole is disposed through the thread pressing and coupling portion and configured to be connected to a thread, and the first and second ends of the body are configured to be pressed by a press machine to attach the thread thereto.

5. The needle instrument of claim 4, wherein the body has a rounded edge.
