Tension-reducing skin sewing thread feeding method

The invention discloses a tension-reducing skin sewing thread feeding method. According to the tension-reducing skin suture line feeding method, a suture needle is ejected out through a suture instrument, and then a barb suture line used for skin suture is sent out; a plurality of suture needles are arranged on the stitching instrument, each suture needle is provided with an independently arranged barb suture line in a penetrating manner, and the barb suture lines can be separated from the suture needles; the stitching instrument comprises a needle changing mechanism used for switching ejected stitching needles. The stitching instrument comprises a firing mechanism used for firing the stitching needle to be ejected out. 本发明公开了减张皮肤缝合送线方法。减张皮肤缝合送线方法，通过缝合器将缝合针射出，进而送出用于皮肤缝合的倒刺缝合线；所述缝合器上设有多个缝合针，每个缝合针上穿设有独立设置的倒刺缝合线，所述倒刺缝合线可从缝合针上脱离出；所述缝合器包括用于切换射出的缝合针的换针机构；所述缝合器包括用于击发缝合针射出的击发机构。
