Description

Technical Field

[0001] The utility model relates to the technical field of cutting scissors, in particular to a pair of blood clot cutting scissors. Background Art

[0002] A blood clot is a lumpy substance formed on the blood vessel wall by coagulation factors in the blood. When the blood vessel is injured or otherwise stimulated, the coagulation system will be activated, causing the blood to coagulate and form a blood clot to stop bleeding and repair damaged tissue. During the medical process, the blood clot needs to be cut and removed to ensure normal blood flow and prevent thrombosis. In view of this, traditional devices are not perfect and there are no facilities for convenient removal of blood clots. A pair of blood clot cutting scissors can provide convenience for staff.

[0003] Patent document: JP3223689U, discloses medical scissors. The above disclosed medical scissors mainly consider the problem of how to be less likely to cause camera shake in surgical operations such as microsurgery in neurosurgery that require high stability and precision, but do not consider the problem of facilitating the removal of blood clots.

[0004] Existing blood clot cutting scissors can usually only perform simple shearing on blood clots, and cannot completely cut off relatively stubborn blood clots, which is inconvenient to remove blood clots and reduces practicality. Utility Model Content

[0005] The utility model aims to provide a pair of blood clot cutting scissors, which can solve the technical problems of the prior art that it is inconvenient to cut blood clots and the practicability is low.

[0007] The cutting assembly includes a square groove, and the square groove is opened on the side where the left scissors and the right scissors are close to each other. A column groove is opened inside the left scissors, and the column groove is communicated with the square groove. A through hole is opened on the top of the left scissors, and the through hole is communicated with the column groove. A thin rod is placed on the inner side of the column groove, a cutting knife is installed on one side of the thin rod, and the cutting knife is located on the inner side of the square groove, and a moving rod is installed on the top of the thin rod, and the moving rod passes through the inner side of the through hole.

[0008] Preferably, a central axis is installed on the top of the left scissors, and the central axis passes through the inside of the right scissors. The inside of the left scissors and the right scissors are provided with a fixing component, and the fixing component is used to fix the left scissors and the right scissors.

[0009] Preferably, a rubber sleeve is installed on the outer side of the thin rod.

[0010] Preferably, a rotating plate is installed on the top of the right scissors through a bearing, a perforated plate is installed on the top of the rotating plate, the width of the hole inside the perforated plate is slightly larger than the diameter of the moving rod, and a grab bar is installed on one side of the perforated plate.

[0011] Preferably, the fixing assembly includes an arc groove, and the arc groove is opened inside the left scissors, and a limiting hole is opened on the top of the left scissors, and the limiting hole is communicated with the arc groove.

[0012] Preferably, a spring is placed inside the arc groove, an arc column is installed at one end of the spring, a round ball is installed on the top of the arc column, and the round ball passes through the interior of the limiting hole.

[0013] Preferably, a placement groove is provided on the top of the right scissors, an elastic rope is installed on the inner side of the placement groove, and a fixing ring is installed on one end of the elastic rope.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model is equipped with a cutting assembly. The staff grasps the grab bar in the cutting assembly and rotates it counterclockwise 180 degrees to rotate the orifice plate to the outside of the moving rod. Then, the staff grasps the grab bar and makes a back-and-forth reciprocating motion, so that the moving rod drives the cutting knife to make a reciprocating motion through the thin rod to cut the blood clot.

[0016] 2. The utility model is equipped with a fixing ring. After the staff clamps the blood clot with the left and right scissors, they grab the fixing ring and move it in the direction away from the right scissors, so that the fixing ring drives the elastic rope to move out of the inner side of the placement groove under the left and right external force. Then, the fixing ring is pulled to move in the direction of the left scissors, so that the fixing ring drives the elastic rope to stretch, and the fixing ring is moved to the position of the ball. The fixing ring is mounted on the outside of the ball. After loosening the fixing ring, the elastic rope shrinks under its own elastic force, so that the elastic rope drives the ball to move in the direction of the right scissors through the fixing ring. The ball drives the arc column to move along the inner side of the arc groove, so that the arc column squeezes the spring to compress and deform, and the left and right scissors are fixed by the elastic rope and the spring.
