Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a costal cartilage cutting scissors includes:

the handle comprises an outer handle 1, wherein the outer handle 1 is a hollow pipe, a handle cover 10 integrally connected with the outer handle is arranged on the right side of the outer handle 1, and a rectangular hole 101 is formed in the handle cover 10;

the adjusting part 2 comprises an inner rod 20 and a plurality of adjusting springs 21, a conical cavity 201 is formed in the right end of the inner rod 20, and two ends of each adjusting spring 21 are fixedly connected to the inner side of the handle cover 10 and the left end of the inner rod 20 respectively;

the left end of the cutting scissors 3 penetrates through the handle cover 10 and is fixedly connected with the handle cover, and the left end of the cutting scissors 3 is located on the inner side of the conical cavity 201.

When the cutting scissors are used specifically, the inner rod 20 is pressed at first, the inner rod 20 moves rightwards, the cutting scissors 3 are fixed relative to the outer handle 1, the movement of the inner rod 20 enables the part of the blade 32, which is positioned at the left end of the hinge shaft 31, to move leftwards relative to the conical cavity 201, the left end of the cutting scissors 3 is slowly closed due to the change of the inner diameter of the conical cavity 201, the right end of the cutting scissors 3 is also slowly closed under the action of the hinge shaft 31, after the cutting scissors 3 are closed, the circular groove 202 on the inner rod 20 is just positioned at the lower end of the movable column 11, the movable column 11 is screwed to be adjusted to be embedded into the circular groove 202, the cutting scissors 3 are always in a closed state at the moment, then the cutting scissors are stretched into a cut wound and moved to a position needing to be cut, and in the process, due to the elastic puncture-proof pad 320 arranged at the front end of the blade 32, organs or other tissues in the wound of a patient cannot be injured even if the cutting scissors are stretched deeply, reduce the risk of operation, treat the position and confirm the back, press interior pole 20, unscrew movable post 11 afterwards, slowly loosen interior pole 20, because the shifting up of movable post 11, interior pole 20 loses external force and to its fixed, under the spring action of regulating spring 21, interior pole 20 moves left, surely gets 3 left ends of cutting and withdraws from conical cavity 201 slowly, under pressure spring 30's effect, surely gets to cut 3 slowly to be in the open mode, later on to the rib cartilage cut can.

Specifically, the cutting scissors 3 comprise a pressure spring 30, a hinge shaft 31 and two groups of blades 32, the blades 32 are movably connected with the hinge shaft 31, the two groups of blades 32 are in a cross shape, two ends of the hinge shaft 31 are fixedly connected to the hole wall of the rectangular hole 101, and two ends of the pressure spring 30 are respectively fixed at the left ends of the two groups of blades 32; the blade 32 can be automatically opened by the elasticity of the pressure spring 30 after being closed by the action of the pressure spring 30, and the situation that the blade cannot be opened again for cutting after being closed can not occur.

Specifically, two groups of strip-shaped grooves 2010 are arranged on the wall of the conical cavity 201, and the right end of the blade 32 is positioned on the inner side of the strip-shaped grooves 2010; the left end of the blade 32 is limited in position by a strip-shaped groove 2010 arranged in the conical cavity 201, and the hinge shaft 31 is further assisted to fix the blade.

Specifically, a circular groove 202 is formed in the upper side of the left end of the inner rod 20, a movable column 11 matched with the circular groove 202 is arranged at the left end of the outer handle 1, and the movable column 11 is in threaded connection with the outer handle 1; the movable column 11 can be embedded into the circular groove 202 through adjusting the position thereof, and the cutting scissors 3 can be ensured to be in a closed state without external force.

Specifically, the length of the blade 32 at the left end of the hinge shaft 31 is smaller than that at the right end of the hinge shaft 31; the difference in length of blades 32 at the left and right ends of hinge shaft 31 ensures that a small amount of change at the left end can result in a large amount of change at the right end.

Specifically, an elastic anti-stab pad 320 fixedly connected with the right end of the blade 32 is arranged on the right end of the blade, and the elastic anti-stab pad 320 is made of a rubber material; when the blade 32 is inserted into the wound of the patient, the elastic anti-stab pad 320 can effectively prevent the blade 32 from causing secondary damage to the organ or tissue of the patient when the blade is inserted too deeply.

Specifically, the outer handle 1 is carved with anti-skid grains 12; the anti-slip lines 12 are arranged to prevent the medical staff from slipping when holding the medical staff.

The present invention has been further described with reference to the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
