Small needle-knife system for removing human body capillary thrombus by using negative pressure

Abstract

The invention discloses a small needle-knife system for removing human body capillary thrombus by using negative pressure. The small needle-knife system is a disposable tool and consists of a negative pressure tank, a small needle-knife fixing body and small needle-knives; the negative pressure tank is formed by high-molecular non-toxic transparent plastic through injection molding or blow molding, and a section of conical tank body is arranged in the middle of the negative pressure tank; the small needle-knife fixing body is a cone made of medical plastic and is fixed at the conical tank body; a plurality of grooves are uniformly and symmetrically formed in the outer side of the small needle-knife fixing body; the small needle-knife fixing body and the six small needle-knives are poured into a whole; the six small needle-knives are arranged in a plum blossom shape, and the small needle-knives are stainless steel hollow miniature needle-knives. The small needle-knife system is convenient to use, puncture and aspiration can be directly, quickly and flexibly completed to remove thrombus, the operation time is shortened, and the pain of a patient is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a small needle-knife system for removing human capillary thrombus by using negative pressure suction. Background technique [0002] "Huangdi Neijing" said: "All diseases are born in Qi", and stagnation of Qi leads to blood stasis. Blood stasis produces blockage, blockage leads to blockage, blockage leads to pain. Stasis in Chinese medicine is also called stasis. Stasis Deposition Wherever the stasis is blocked in the body, it will cause pain or discomfort in that part, and become a new healing factor. The biggest harm of stasis to human beings is that it is easy to cause stroke and myocardial infarction. The blood stasis in traditional Chinese medicine is blocked, and the western medicine is called thrombus. According to the type of blood vessel, it can be divided into arterial thrombosis, venous thrombosis and capillary thrombosis. Pain in the head, neck, shoulders, b...

Problems solved by technology

However, these operations are too cumbersome: first, use a puncture needle to pierce the blood stasis site several times in different numbers, and then use a negative pressure tank with a negative pressure device to suck out the blood stasis tissue. After reaching a certain level, clamp the negative pressure tube and loosen the edge of the tank to let the stagnant tissue in the tank flow out, and an assistant holds a sterilized curved plate to catch the outflowing blood waste; then buckle up the negative pressure tank and continue to suck until the suction is finished until

Whether the patient is lying down or sitting, the curved plate will flow out to varying degrees when collecting blood waste, and it will flow all over the back if you are not careful, it is difficult to enter the curved plate without leaking; and repeated operations, If the disinfection is not strict, it will easily lead to infection, and the operation time will be significantly prolonged, which will undoubtedly increase the pain of the patient
