specific Embodiment 2

[0028] This embodiment is the preparation method of polymer antibacterial coating:

[0029] Step A: polyvinylpyridinone and organic solvent are mixed, so that polyvinylpyridinone is completely dissolved in the middle of the organic solvent to form a solution, the organic solvent is formamide, and the concentration of polyvinylpyridinone in the solution is 1g / L

[0030] Step B: adding styrene monomer to the solution after step A, the ratio of the amount of styrene monomer to the repeating unit in polyvinylpyridinone is 0.1;

[0031] Step C: Stir the solution after step B by magnetic force for 10 hours;

[0032] Step D: adding concentrated sulfuric acid to the mixture of step C, so that the pH of the solution is controlled between 5;

[0033] Step E: Add initiator benzoyl peroxide to the solution after step D, and described initiator is 0.01%wt of polyvinylpyridinone;

[0034] Step F: react at 100° C. for 1 hour;

[0035] Step E: Cool the solution, add inorganic salt to the...

Abstract

The invention discloses a pair of antibacterial tissue forceps. The pair of antibacterial tissue forceps comprises forcep handles and a forcep jaw, wherein a polymer antibacteirla coating layer is arranged on the forcep jaw, and the thickness of the polymer antibacterial coating layer is 10 to 100mu m.

Description

technical field [0001] The present invention relates to medical supplies. Background technique [0002] Medical tissue forceps are mainly used to hold cotton wool for coating medicinal materials or hold gauze for wound filling and dressing, but in fact they can also be used for surgery to hold fragile soft tissues such as mucous membranes, blood vessels, and nerves. [0003] Existing medical tissue forceps are generally made of metal materials, and are composed of two left and right forceps through hinged joints. The front ends of the left and right forceps are flat. [0004] The direction of the existing tissue forceps remains fixed when the forceps head is in use, and when the forceps head needs to be rotated, the forceps handle also needs to be rotated correspondingly, which is extremely inconvenient to use. Contents of the invention [0005] The purpose of the present invention is to solve the above problems, to provide a kind of tissue forceps, including a forceps ha...
