What kind of stitches do you have?

1, circular suture needle: mainly used for soft and easy-to-penetrate tissues, such as peritoneum, gastrointestinal tract and heart tissue, with little damage when passing through.

2. Triangular sewing needle: suitable for tough tissues, the needle tip is triangular and the needle body is round.

3. Triangular angle needle: the point from the needle tip to the waist line is triangular, which is used to puncture tough and difficult tissues, such as fascia and skin.

4. Metal wallet: This kind of metal money is packed in a special nail box and clamped with a special clip, which is mostly used for skin suture and orthopedic surgery.

Extended data:

The sewing needle consists of three basic parts, namely, the needle tip, the needle body and the needle eye. According to the shape, the needle tip can be divided into three types: round head, triangular head and shovel head: the needle body has three types: near round head, triangular head and shovel head. Needle eye is a hole for lead wire, which has two kinds: ordinary hole and bullet hole.

According to different radians, circular needles are divided into 1/2, 3/8 radians, etc. Large radians are mostly used in deep tissues. The front half of triangular needle is triangular and sharp, which is used to sew tough tissues such as skin, cartilage and ligament, and has great lethality.

Whether round needle or triangular needle is used, in principle, the one with smaller needle diameter should be chosen, which has less damage, but sometimes the tissue has greater toughness and is easy to break when the needle diameter is too small, so it should be chosen reasonably. In addition, when sewing with curved needle, it should be pulled out from the tissue along the arc of curved needle, otherwise it will be easily broken.
