The influence of the structure of surgical instruments on operated tissues of animals

The purpose of the research was to study the effect of the microstructure of various cutting elements in the surgery on tissue regeneration. The problem was in the increase of the number of postoperative complications and cases of prolonged wound healing, and sometimes the transition of an acute process to chronic, which indicates unresolved issues of postoperative regeneration of damaged tissues. In order to study regenerative features of tissues, diverse operations (n = 28) were performed in calves, goats, and dogs. In addition to cutting tools, the pointed part of the spokes for transosseous osteosynthesis, as well as the saws for amputation of horns, fetotomy in cows and goats, were investigated. Using a Hitachi TM-1000 scanning electron microscope, the microstructure of the surface of the cutting part of various tools was analyzed in the low vacuum Standart Mode. At the same time, it was found that during the cuts with a carbon steel blade, there was slight difficulty in cutting tissues due to “the saw effect” less pronounced for it, in contrast to surgical stainless steel blade, but at the same time, during tissue regeneration after suturing less wound was observed than when using a stainless steel blade...
