Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1 and 2, in order to achieve the above object, the present invention provides the following technical solutions: a pair of costal cartilage scissors comprises a first handle part 1 for inserting a thumb and a second handle part 2 for inserting other fingers, wherein the first handle part 1 is connected with a first blade part 11, the second handle part 2 is connected with a second blade part 21, the joint of the first blade part 11 and the first handle part 1 and the joint of the second blade part 21 and the second handle part 2 are hinged through a hinge shaft 3, a user inserts the thumb and the other operating finger into the first handle part 1 and the second handle part 2 respectively, and the cutting operation of the first blade part 11 and the second blade part 21 is controlled by moving the positions of the first handle part 1 and the second handle part 2 up and down;

the first blade part 11 and the second blade part 21 are arranged in an axial overlapped state of the hinge shaft 3, the first blade part 11 comprises a first cutting edge 111 for cutting costal cartilage and a first back part 112 far away from one side of the costal cartilage, the second blade part 21 comprises a second cutting edge 211 for cutting the costal cartilage and a second back part 212 far away from one side of the costal cartilage, the end surface of the first blade part 11 far away from the first handle part 1, the first cutting edge 111 and the first back part 112 are respectively provided with a first cambered surface 6 protruding outwards, the first cambered surfaces 6 surround a rounded blunt point 4 on the first blade part 11, the end surface of the second blade part 21 far away from the second handle part 2, the second cutting edge 211 and the second back part 212 are respectively provided with a second cambered surface 7 protruding outwards, and only the end surface of the second blade part 21 far away from the second handle part 2, the second cutting edge 211, the second blade part 21 and the second back part 112 are arranged in an axial overlapped state, The end face of the first blade part 11 far from the first handle part 1, the first cutting edge 111 and the first back part 112 are provided with a first arc surface 6 and a second arc surface 7, because these surfaces have probability to contact with skin and tissue on the peripheral side, and the surfaces on both sides in the cutting direction are not provided with the first arc surface 6 and the second arc surface 7 (which can contact with costal cartilage in the cutting process to cause failure in cutting). The second cambered surfaces 7 are encircled to form round and blunt points 4 on the second blade parts 21, the first cutting edges 111 and the second cutting edges 211 are used for cutting costal cartilage, the round and blunt points 4 are designed to avoid puncturing tissues when a user pulls the operation wound open through a draw hook to enable costal cartilage scissors to extend from the wound position to touch skin tissues at the wound position, and damage is caused until the first blade parts 11 and the second blade parts 21 are respectively positioned at the upper side and the lower side of the costal cartilage to be cut, and the phenomena of puncturing and skin puncture in the tissues are avoided in the cutting process, so that the smooth proceeding of the operation progress is protected, and the operation safety is guaranteed.

The first blade portion 11 and the second blade portion 21 are both arranged in an arc-shaped structure and can surround costal cartilage in a surrounding manner, when one ends of the first blade portion 11 and the second blade portion 21, which are far away from the first handle portion 1 and the second handle portion 2, are in an overlapped state, the first handle portion 1 and the second handle portion 2 are in an opened state, and when the first handle portion 1 and the second handle portion 2 are in a closed state, the arc-shaped bottom of the first cutting edge 111 and the arc-shaped bottom of the second cutting edge 211 are overlapped. The first blade part 11 and the second blade part 21 can closely move to perform a cutting operation like a common scissor head, one ends of the first blade part 11 and the second blade part 21 far away from the first handle part 1 and the second handle part 2 are overlapped in a staggered manner in different planes, and the first handle part 1 and the second handle part 2 are closed in a state that the same planes are mutually abutted. The arc-shaped structures of the first blade part 11 and the second blade part 21 are arranged to have the advantages that: firstly, the cutting operation can be simultaneously carried out from the root and the top of the first blade part 11 and the second blade part 21, the cutting speed is increased, and the operation efficiency is improved; and secondly, the contact area between the first blade part 11 and the second blade part 21 and costal cartilage is increased, so that the effect of firm clamping is achieved.

The round blunt points 4 are all arranged in a cambered surface structure. As shown in fig. 1, when the first back portion 112 and the second back portion 212 are also arranged in an arc-shaped structure, the height of the protrusion of the rounded blunt point 4 is not higher than the highest arc-shaped point of the first back portion 112 or the second back portion 212, so that the situation of inconvenient insertion due to the overlarge end structures of the first blade portion 11 and the second blade portion 21 when the first back portion 112 or the second back portion 212 is inserted into a wound in the previous period is avoided, and in addition, the rounded blunt point 4 in the arc-shaped structure has a sufficient rounded radian, so that the effect of avoiding stabbing tissues can be achieved, and the first back portion 112 and the second back portion 212 can be conveniently placed.

The first cutting edge 111 and the second cutting edge 211 are respectively provided with a plurality of cutting teeth 5 for fixing and cutting costal cartilage, and the cutting teeth 5 are respectively arranged along the length direction of the first cutting edge 111 and the second cutting edge 211. The design of this cutting tooth 5 guarantees that the clamping process is enough firm, and the phenomenon of sliding is difficult to appear, has avoided cutting the in-process rib cartilage to cut and has slided and cause the shearing angle to change, cut the position and take place phenomenons such as shift to lead to the appearance of cutting the error, cutting the failure scheduling problem.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
