METHOD FOR PATIENT PREPARATION FOR SURGICAL INTERVENTION Russian patent published in 2015 - IPC A61B17/02 A61B1/32 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, to surgery. A patient is fixed on a surgical table. An anaesthesia care is provided. That is followed by approaching from a superior-median laparotomy. Wound retractor hooks have an effect on the ribcage and breast bone. That is combined with forming a surgical approach, first by separating the incision wound edges with two rib hooks for normosthenic, asthenic and hypersthenic types. $$0,053\le \frac{F_n}{S\times 1,23}\le 0,056$$ for normosthenic type; $$0,056\le \frac{F_{а}}{S\times 1,32}\le 0,060$$ for asthenic type; $$0,042\le \frac{F_h}{S\times 1,36}\le 0,049$$ for hypersthenic type, wherein F_n, F_a, F_h is a force of separating the incision wound edges, kilogram-force. 0.053; 0.056; 0.042; 0.056; 0.060; 0.049 is a pressure of the rib hook of the wound retractor on the wound edge after approaching the wound, kgf/cm²; S is an area of the rib hook of the wound retractor, cm²; 1.23; 1.32; 1.36 is an average resistance coefficient of the ribcage. Overhanging soft tissues of the incision wound edge are eliminated with the rib hook along the patient's mid-line.

EFFECT: method provides the adequate wound opening with the low number of patient's injuries, improves the objective control when performing the surgical approach.
