Description

Surgical scissors

Technical Field

The utility model relates to a medical instrument technical field particularly, relates to a surgical scissors.

Background

The surgical scissors are medical instruments commonly used in clinical operations and mainly used for cutting off coarse soft tissues such as skin or muscles. According to its structure characteristics, it has various forms of tip, blunt, straight, bent, long and short. The applications of the Scissors are Tissue Scissors (Tissue Scissors) and thread Scissors (Stitch Scissors).

Tissue scissors are mostly curved scissors, which are sharp and fine for dissecting, cutting or separating the cut tissues. Generally, straight scissors are used for superficial surgery operation, and curved scissors are used for deep surgery operation.

The thread Scissors are mostly straight Scissors, and are divided into a thread Scissors and a thread removing Scissors (Ligature Scissors), wherein the former is used for cutting off a suture, a dressing, a drainage tube and the like, and the latter is used for removing the suture. The difference between the thread scissors and the tissue scissors is that the edge of the tissue scissors is sharp and thin, and the edge of the thread scissors is blunt and thick. The stitch scissors are straight scissors with one blunt concave page and one straight sharp page and are used for removing stitches.

The existing thread scissors are easy to have thread slipping when in use, and the length of the cut thread end can not be accurately controlled. If the remained thread end is too long, the remained thread left on the tissue is too much, and the healing of the incision is easily influenced; if the remaining thread ends are too short, the knots can easily come loose and the cuts can easily split, causing undesirable consequences. Thus, the prior art has yet to be improved.

Examples

Referring to fig. 1 to 6, a pair of surgical scissors according to an embodiment of the present invention is shown, and has the following specific structure.

As shown in FIG. 1, the present application is provided with the surgical scissors in a vertical position. The surgical scissors comprise a scissors body 1. The scissors main body 1 consists of three parts, namely a double handle, a joint part and a shearing part, wherein the shearing part mainly comprises an inclined blade surface and a flat blade surface and is used for shearing a suture line; the tail ends of the two handles are convenient to master and operate by hands; the joint is used for connecting two double handles, and the structure of the part is the prior art. The scissors main body 1 is provided with a thread end fixing clamping groove 101, and the side edge of the scissors main body 1 is provided with a groove 102. The thread end fixing clamping groove 101 is positioned between the shearing part and the combining part, as shown in fig. 1, when the two handles of the scissors main body 1 are opened, the thread end fixing clamping groove 101 is a semicircular gap on the two handles, so that a suture can be conveniently placed into the thread end fixing clamping groove 101; as shown in fig. 2, when the two handles of the scissors body 1 are closed, the thread end fixing slot 101 is a circular through hole, and can fix the thread end to prevent sliding. The scissors main body 1 is provided with grooves 102 on both sides, and the grooves 102 are substantially V-shaped grooves for passing a suture.

When the scissors are used, the two handles of the scissors main body 1 are opened (the condition is shown in figure 1), the thread end fixing clamping groove 101 is also separated and clamped into a suture, then the two handles of the scissors main body 1 are closed (the condition is shown in figure 2), the suture slides to a knot of the suture along the closed thread end fixing clamping groove 101, the suture cannot slide at the moment, the suture bypasses the groove 102 on the outer side, and finally the suture returns to a position between the two edges of the cutting part to cut the thread. The whole process is very simple to operate, the knot of the suture is clamped in the thread end fixing clamping groove 101 and is wound through the groove 102 on one side, the slippage of the suture is effectively avoided, and the length of the cut thread end is accurately controlled. Therefore, the surgical scissors provided by the embodiment of the utility model have the advantages of simple use and prevention of thread slipping during thread cutting.

It should be noted that, when the thread is cut, the double blades of the cutting portion act slightly, and the thread end fixing groove 101 does not open too much, thereby preventing the thread knot from slipping off.

In some embodiments of the present invention, the scissors body 1 is provided with a blunt scissors head 2. As shown in fig. 1 and 2, the tip of the round and blunt scissor head 2 is in a circular arc transition shape to block the blade face, so as to avoid unnecessary injury caused by the fact that the sharp blade face or the blade tip injures human tissues. Therefore, the surgical scissors of the embodiment are safer to use than the conventional surgical scissors.
