Problems solved by technology

[0003] Since the puncture cannula is to be inserted into the human body, the puncture cannula is required to have strong antibacterial properties, but the antibacterial properties of the puncture cannula currently used are poor, and some even have no antibacterial properties. Carry out certain sterilization and disinfection treatment; this makes the operation have certain safety hazards, reduces the success rate of the operation, and may affect the patient's later recovery
However, there is no surgical puncture sleeve with strong antibacterial properties on the market at present.

Abstract

The invention discloses a surgical puncture sleeve, which is optimized by using polypropylene as the base material and adding various auxiliary agents such as plasticizer; by adding dimethyl dodecyl benzyl ammonium chloride, 2,2 Bis(hydroxymethyl)‑1,3‑propanediol allyl ether, 3‑methacryloxypropylmethyldimethoxysilane1 and 2'4'‑difluoro‑2‑[1‑( 1H‑1,2,4‑triazolyl)]acetophenone These substances have improved the antibacterial properties of antibacterial polymer materials, and at the same time by adding dimethylaminopropyl methacrylamide, dioctyl dodecyl alcohol di Substances such as polylinoleate and 3-glycidyl etheroxypropyl triethoxysilane greatly improve the dispersibility of antibacterial substances in polypropylene, so that antibacterial substances can be evenly dispersed in polypropylene, and at the same time improve antibacterial properties. Synergy between substances and other additives. The surgical puncture cannula finally prepared by the present invention has strong antibacterial performance, even under acidic or alkaline conditions, it still has strong antibacterial performance.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a surgical puncture sleeve. Background technique [0002] The puncture cannula is a commonly used medical device used in various minimally invasive operations, such as laparoscopic surgery, venous surgery, etc.; medical staff first insert the puncture cannula into a specific part of the human body through a puncture needle, and then pull it out The puncture needle enables medical staff to inject drugs into specific parts of the human body through the puncture cannula and other treatment methods, reducing the harm to the patient and ensuring the success of the operation. [0003] Since the puncture cannula is to be inserted into the human body, the puncture cannula is required to have strong antibacterial properties, but the antibacterial properties of the puncture cannula currently used are poor, and some even have no antibacterial properties. Carry out certain sterilization and...
