Problems solved by technology

[0002] When occluding the superior and inferior vena cava during surgery, it is necessary to cuff the superior and inferior vena cava first to fix the cannula inserted into the superior and inferior vena cava. The step of cuffing during the operation is very complicated, the operation takes a long time, and the operation is easy to damage The aorta, pulmonary artery, and superior and inferior vena cava cause the risk of massive bleeding. In addition, this operation method is more difficult in small incision and thoracoscopic heart surgery, and it is more likely to cause the risk of massive bleeding

Embodiment Construction

[0016] Such as Figure 1-Figure 2 The upper and lower vena cava occlusion clamp shown without a sleeve includes two first connecting sections 1 and second connecting sections 2 arranged in parallel, and the opposite inner surfaces of the first connecting section 1 and the second connecting section 2 are affixed together In this embodiment, the upper parts of the first connecting section 1 and the second connecting section 2 are connected together by bolts. The lower end of the first connection section 1 extends downwards to form a first handle section 11 which is inclined relatively outward, and the lower end of the second connection section 2 extends downward to form a second handle section 21 which is inclined relatively outward. The outer surfaces of the handle segment 11 and the second handle segment 21 are provided with anti-skid lines. The lower end of the first handle section 11 extends downward to form a relatively inwardly bent first cross section 12 , and the lower ...

Abstract

The invention discloses a tape-free superior and inferior vena cava blocking clip. While a cannula is inserted in the superior and inferior vena cava, the first handle section and the second handle section are pressed, so the first arc section and the second semi-arc section are opened, and a blood vessel is sent between the first arc section and the second semi-arc section through the first bluntend part and the second blunt end part, so the blood vessel can be clamped and blocked, and the blood vessel is prevented from being injured by a first connecting handle and a second connecting handle through the first blunt end part and the second blunt end part. The first arc section and the second semi-arc section are butted to form a circular cavity for blocking the blood vessel. A tape stepcan be avoided, and risks, such as massive haemorrhage, in an operation are reduced. According to the space size of the blood vessel position, the lengths of the first blunt end part and the second blunt end part are adjusted, and soft tissues are prevented from being injured.

Description

technical field [0001] The invention relates to a band-free superior and inferior vena cava blocking clip. Background technique [0002] When occluding the superior and inferior vena cava during surgery, it is necessary to cuff the superior and inferior vena cava first to fix the cannula inserted into the superior and inferior vena cava. The step of cuffing during the operation is very complicated, the operation takes a long time, and the operation is easy to damage The aorta, pulmonary artery, and superior and inferior vena cava cause the risk of massive bleeding. In addition, this operation method is more difficult in small incision and thoracoscopic heart surgery, and it is more likely to cause the risk of massive bleeding. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the above defects and provide a cuff-free superior and inferior vena cava occlusion clamp, which facilitates the occlusion of the superior an...
