Problems solved by technology

At present, siliconization is mostly used, that is, smearing or dipping silicone oil on the tip of the needle as a lubricant; although medical silicone oil is non-toxic and tasteless, it is a chemical product after all, and the residue will change the structure of the body tissue when used

Embodiment

[0015] The blending ratio of coating materials: Panax notoginseng 20-25%, white root 10-15%, coriander root 8-10%, gallic acid 10-20%, shikonin 10-20%, calcium stearate 20-30% %.

[0016] Put the raw materials of the above raw material ratio into the reaction kettle, control the temperature in the kettle at 40-60°C, stir for 4-6 hours, take the clear liquid through filtration, and then heat and concentrate for 0.5 hours to become a clear and transparent light yellow slurry, and then in Store in a sealed thermostatic container at 30-40°C for later use.

[0017] In a closed 10,000-class clean room, keep the indoor temperature at 25-28°C and the relative humidity at 15-30%, take 15-20ml of the coating liquid and put it in a glass dish, soak the suture needle in the coating liquid, the needle tip is completely Immerse in the liquid (according to the actual situation, it is best not to exceed the height of the needle), soak for 30-60 minutes, take it out and dry it, and the coatin...

Abstract

The invention relates to the field of medical instruments and in particular discloses an antibacterial suture needle coating method. The antibacterial suture needle coating method is characterized by comprising the steps of adding Panax pseudoginseng, rhizoma bletillae, lalang grass rhizome, gallic acid, alkannin and calcium stearate as raw materials into a reaction kettle, heating while stirring, filtering to obtain clear liquid, and heating and concentrating the clear liquid to obtain clear transparent yellowish coating slurry; and placing the coating slurry in a glass dish in a closed clean workshop, soaking a suture needle into the coating slurry, and taking out and airing to achieving the coating purpose. The suture needle has good antisepsis and anti-inflammation effects and good antioxidant and degradation properties, after clinical application, the suture needle has a wide application range and a good effect, and allergy, irritation or inflammatory responses are not found; the suture needle has sterilizing, inflammation-diminishing and antibacterial functions and can improve the wound strength and accelerate wound healing.

Description

(1) Technical field [0001] The invention relates to the field of medical appliances, in particular to an antibacterial suture needle coating method. (2) Background technology [0002] Medical suture needles are mainly used for surgical sutures. The raw materials are mostly made of stainless steel wires drilled or slotted at the end of the needle. The surface should be very smooth after polishing and electrolytic treatment; however, no matter how acidified, electrolyzed and polished, the surface of the needle body is always There are tiny burrs that cannot be observed by the naked eye, so when the human muscle tissue is sutured, the neurons of the muscle tissue will always be damaged, and the patient will feel pain. [0003] In order to alleviate the patient's muscle pain during suturing, people think of adding a coating to the needle body. The purpose is to make the needle body smoother after coating, and it is easier to puncture tissue than other suture needles, so as t...
