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. Polypropylene is taken as a base material, and various auxiliaries like a plasticizer are added for optimization; by adding dimethyl dodecyl benzylamine chloride, 2, 2-bis(hydroxymethyl)-1, 3-propylene glycol allyl ether, 3-methacryloxy propyl methyl dimethoxysilane 1 and 2' 4'-difluoro-2-[1-(1H-1, 2, 4-3-triazole)]acetophenone, these substancesimprove antibacterial performance of an antibacterial high-molecular material; by adding dimethylamino propyl methacrylamide, dioctyl dodecyl alcohol dilinoleate and 3-glycidyl ether oxy-propyl triethoxysilane, these substances greatly improve dispersity of the antibacterial material in polypropylene, so that the antibacterial substance can be uniformly dispersed in polypropylene, and synergism between the antibacterial material and other auxiliaries is improved. The finally obtained surgical puncture sleeve has great antibacterial performance and still has good antibacterial performance evenin acidic or alkaline conditions.

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...
