外科缝线基础知识（Basics of surgical sutures） Surgical suture is an essential material for surgeons, download this knowledge from other sites, I hope useful for everyone The ideal suture material should meet the following conditions: 1. general, which can be applied to any surgery (of course, should also take into account the suture type and tensile strength on the difference); 2. aseptic; No, no 3. electrolytic capillary effect, no allergic and non carcinogenic; 4. if using stainless steel suture, without magnetic; 5. easy to operate; 6. tissue reactions are mild, not conducive to the growth of bacteria; 7. knots without loosening or rupture caused by suture itself does not wear; 8. not contraction within the organization; 9. suture aim is achieved, which can be absorbed and caused only slight reaction. However, due to the versatility of this ideal suture did not exist at present, so the surgeon must be selected as close to the ideal and have the following characteristics of suture: 1. tensile strength uniform, to use a fine type of suture; 2. seam of uniform diameter and constant; 3. aseptic; 4. strong flexibility, make the operation convenient, safe ligation; 5. do not contain irritating substances or impurities in tissue compatibility; The 6. stitching results can be trusted. Type and tensile strength Showing the type of suture material diameter. Surgical practice recognized, should be used to make the most of the organization for security and fine type of suture, the suture caused by trauma to a minimum. The type of suture in digital said: 0 above, the higher the number, the suture is thicker, such as rough on the No. 3 No. 1; from 0, 0, more and more small diameter, the tensile strength is low. The tensile strength of suture knot is will stand before breaking its efforts (in pounds). The tensile strength of the organization is surgeons to choose the type and suture prerequisite of tensile strength. The surgeon should also understand, thread strength decreasing and the
