It can also be used to separate tissue, i.e. using the tip of scissors to insert into the tissue space, to separate connective tissue without large blood vessels, etc.

The surgical scissors are sharp, blunt, straight, curved, long and short according to the structural characteristics. Surgical scissors are classified into tissue scissors and thread scissors according to the purposes. The tissue scissors are mostly bent scissors, and are used for dissecting, cutting or separating the cut tissues sharply and finely. Generally, straight scissors are used for superficial surgery operation, and curved scissors are used for deep surgery operation. The thread scissors are mostly direct scissors, and are divided into thread scissors for cutting off the thread, dressing, drainage tube, etc. and thread scissors for removing the thread. 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 main differences of the surgical scissors with different structures are the length, the structure, the sharpness of the blade and the like of the whole knife body. Therefore, the general structure of the existing surgical scissors is shown in fig. 1, the surgical scissors include two knife bodies 10, each knife body 10 is sequentially provided with a knife edge 101, a knife handle 102 and a finger ring 103 according to the length direction thereof, and the two knife bodies 10 are movably connected; when in use, the fingers of the operator pass through the finger ring 103 for cutting.

Because the fingers of the operators are different in size and the structural schematic diagram of the thumb of the operator is shown in fig. 2, and the finger ring is sleeved on the position, close to the tiger mouth, of the thumb of the operator in the using process of the surgical scissors, the inner diameter of the finger ring is set to be larger so as to ensure that the fingers of the operators with different finger sizes can pass through the finger ring; however, the finger ring has a large inner diameter, is easy to slip, and is not suitable for being grasped and used by an operator with thin fingers.

Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 3 and 4, an embodiment of the utility model provides surgical scissors, which include two movably arranged knife bodies 10, each knife body 10 is sequentially provided with a cutting edge 101, a knife handle 102 and a finger ring 103 according to a length direction thereof, the two knife bodies 10 are movably connected, in order to enable the finger ring 103 to have an anti-slip effect, an anti-slip structure is arranged in each finger ring 103, the anti-slip structure includes a rubber ring 1 attached to an inner wall of the finger ring 103 and a plurality of layers of elastic bodies uniformly distributed along an axial direction of the rubber ring 1, each layer of elastic body includes a plurality of elastic columns 11 annularly arranged along the inner wall of the rubber ring 1, and the plurality of elastic columns 11 respectively arranged on any two adjacent layers of elastic bodies are mutually staggered along the axial direction of the rubber ring 1. The elastic columns 11 on each layer of elastic body are made of the same material as the rubber ring 1. Whole anti-skidding structure is integral type structure, and rubber ring 1 is fixed at the inner wall of ring 103 through sticky mode. The corrosiveness and swelling property of the alcohol to the rubber are small and can be ignored, so that the whole anti-skid structure and the whole surgical scissors can be disinfected by the alcohol.

When the surgical scissors are used, the fingers of an operator penetrate through the multilayer elastic bodies and are placed in the fixed space surrounded by the multilayer elastic bodies. The anti-skidding structure who sets up at ring 103 inner wall can have different effects according to operator's finger size: when the fingers of an operator are thin, the fingers of the operator are in contact with the elastic columns 11 or are arranged in a gap with the elastic columns 11, so that the gap difference between the fingers of the operator and the inner wall of the finger ring 103 is shortened, and the elastic columns 11 are made of the same material as the rubber ring 1 and have an anti-skidding effect, so that the finger ring 103 with the anti-skidding structure can reduce the probability of slipping separation of the operator and the surgical scissors in the process of using the surgical scissors, and ensure the safety of the operator in using the surgical scissors; when the fingers of an operator are thick, the fingers of the operator contact the elastic columns 11 and press the elastic columns 11 to enable the finger ring 103 to be stably clamped on the fingers of the operator, and due to the fact that the elastic columns 11 are in flexible contact with the fingers, damage caused by rigid contact with the fingers of the operator when the finger ring 103 is not provided with an anti-skidding structure is avoided, and the surgical scissors are more suitable for being used for a long time. The finger ring 103 arranged in the utility model can be matched with operators with different fingers in size through the plurality of elastic columns 11, so that the problems of slipping of the surgical scissors in the use process, finger damage caused by long-time rigid contact between the fingers and the finger ring 103 and the like are avoided.

As shown in fig. 4 and 5, since the operator uses the thumb 20 when using the surgical scissors, in view of the structure of the thumb 20, in order to make the multi-layer elastic body pass through the thumb 20 of the operator conveniently and make the thumb 20 of the operator fit with the multi-layer elastic body when using the surgical scissors, the lengths of the plurality of corresponding elastic columns 11 on the multi-layer elastic body are arranged in the axial direction of the rubber ring 1 in a way of decreasing and then increasing. When the number of layers of elastic bodies is set, the number can be determined according to the axial length of the ring 103, five layers of elastic bodies are arranged in the rubber ring 1, and are divided into a first layer of elastic body 12, a second layer of elastic body 13, a third layer of elastic body 14, a fourth layer of elastic body 15 and a fifth layer of elastic body 16 according to the axial direction of the rubber ring 1, wherein the first layer of elastic body 12 and the fifth layer of elastic body 16 are distributed on two sides of the third layer of elastic body 14 in a mirror image manner, the second layer of elastic body 13 and the fourth layer of elastic body 15 are distributed on two sides of the third layer of elastic body 14 in a mirror image manner, and the length of the elastic column 11 of the first layer of elastic body 12, the length of the elastic column 11 of the second layer of elastic body 13 and the length of the elastic column 11 of the third layer of elastic body 14 are sequentially increased.

As shown in fig. 5, the five layers of elastic bodies are distributed along the inner wall of the rubber ring 1 to form a through cavity structure which is approximately reduced and then enlarged, so that the wider part of the thumb 20 of the operator can penetrate through the multiple layers of elastic bodies from two sides of the ring 103, and the narrower part of the thumb 20 of the operator can be in contact with or arranged in a small gap with the elastic columns 11 on the second layer of elastic body 13, the elastic columns 11 on the third layer of elastic body 14 and the elastic columns 11 on the fourth layer of elastic body 15, so that the surgical scissors cannot easily slip and separate from the fingers of the operator even if the thumb 20 of the operator is thinner in the using process.

As shown in fig. 5, since the plurality of elastic columns 11 on the third layer elastic body 14 have the longest length, in order to facilitate sufficient deformation space when the plurality of elastic columns 11 on the third layer elastic body 14 are in contact with the fingers of the operator, the distance between the first layer elastic body 12 and the second layer elastic body 13 is smaller than the distance between the second layer elastic body 13 and the third layer elastic body 14.

As shown in fig. 4, 5, and 6, in order to make each elastic column 11 more deformable and make the contact area when vertically contacting with the fingers of the operator smaller, and not limit the use of the fingers of the operator in the fixed space formed by the multiple layers of elastic bodies, each elastic column 11 includes a cylinder 111 and a hemisphere 112 disposed at one end of the cylinder 111, wherein the other end of the cylinder 111 is fixedly connected with the rubber ring 1.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
