Classification of surgical scissors

According to its structural characteristics, it is pointed, blunt, straight, curved, long and short. According to its purpose, it is divided into Tissue Scissors and Stitch Scissors.

Tissue shears are mostly curved shears, sharp and fine for dissecting, cutting or separating tissue. Straight scissors are usually used for shallow surgery and curved scissors are used for deep surgery ^[1] .

Thread shears are mostly straight shears, which are divided into thread trimmers and Ligature Scissors. The former is used to cut sutures, dressings, and drainage tubes, and the latter is used to remove sutures. The difference between line scissors and tissue scissors is that the blades of tissue scissors are sharp and thin, while the edges of line scissors are blunt and thick. Therefore, we must not make it convenient and greedy. We use tissue shears instead of line shears, which will damage the blade and cause waste. Thread-cutting scissors are one-sided blunt and straight-pointed straight scissors for removing sutures ^[2] .

According to the "Category of Medical Device Classification" promulgated by the State Food and Drug Administration, surgical scissors can be divided into tissue scissors, instrument scissors and endoscope scissors according to their uses. The detailed information is shown in the following table ^[3] .

Endoscope scissors	It is usually composed of a head, a rod or a flexible catheter and a handle. The head is a pair of blades with blades, which are transmitted and controlled by the handle. Generally the head is made of stainless steel.	Operated endoscopically during surgery to cut tissue.	Endoscopic surgical scissors, sinusoscopic surgical scissors, laparoscopic surgical scissors, endoscopic ligature scissors, endoscopic optical scissors

How to use surgical scissors

The correct position for cutting is that the thumb and ring finger (ring finger) are buckled by the two rings of the scissors handle, and the middle finger is placed on the scissors handle of the ring finger. Beginners often make the mistake of holding the middle finger in the handle ring, and this wrong method of cutting does not have a good triangle stabilization effect, which directly affects the stability of the action. When using scissors, the normal shear method is generally used, the reverse shear method can also be used, and the assisted shear method or other operations can also be used ^[2] .

How to use surgical scissors

Making Shear Tips:

1. When cutting tissues, the normal shear method is generally used, and sometimes the reverse shear method is often used. In special cases, the left and right hands can be used to perform shear operations.

2. Sometimes in order to increase the stability, you can also use the shear method. For easy operation. Portable scissors can perform other operations at the same time. Open the scissors slightly while cutting the thread. Slide down to the top edge of the knot. Tilt the scissors up 45 degrees again and cut the thread ^[4] .
