Problems solved by technology

Usually after one operation, the number of repeated in and out of surgical instruments is about 20-30 times on average. However, with such a thickness, the valve is easily damaged when the surgical instruments pass through, causing adverse consequences.
On the one hand, after the damage occurs, the airtightness of the valve will decrease, which cannot realize the stable protection of the patient's abdominal pressure; medical malpractice

Abstract

The invention discloses a valve material of a puncture outfit. The valve material comprises, by weight, 25-45 parts of polydimethylsiloxane, 1.5-3 parts of polymethylsiloxane, 0.5-1.2 parts of platinum complex, 6-13 parts of graphene, 3-7 parts of white mineral oil, 0.2-0.7 part of gel film agent, 6-10 parts of carbon black, 7-15 parts of clay, 2-6 parts of barium sulfate, 0.3-0.5 part of magnesium hydroxide, 1-3 parts of hydroxy fluorosilicon oil, 1-2 parts of polyethylene wax and 1-1.8 parts of glycidyl ether. The invention further discloses a preparation method and application of the valvematerial of the puncture outfit. The valve material of the puncture outfit has the advantages that since a more environment-friendly valve production material is selected, the prepared valve has the characteristics of no unpleasant odor, no toxicity and resistance to high temperature and cold and has outstanding characteristics of physiological inertia and no proneness to blood coagulation; a moreoptimized production technology is adopted, full automatic production can be realized, yield of valve products is increased, production cost is reduced, medical expense burden on patients is reducedfurtherly, and remarkable social benefit is realized.

Description

technical field [0001] The invention relates to a puncture valve material, a preparation method and application thereof, and belongs to the field of medical materials. Background technique [0002] Laparoscopic surgery mostly uses 2-4 hole operations, one of which is opened on the navel of the human body to avoid leaving long strips of scars in the patient's abdominal cavity. After recovery, only 1-3 0.5-hole holes are left in the abdominal cavity. A 1 cm linear scar can be said to be a minimally invasive and painful operation, so some people call it "keyhole" surgery. The development of laparoscopic surgery reduces the pain of surgery for patients, shortens the recovery period of patients, and relatively reduces the expenditure of patients. It is a surgical item that has developed rapidly in recent years. Laparoscopic surgery mainly uses a medical laparoscopic puncture device to puncture the skin to form an operation channel for instruments and optical eyepieces, which con...
