METHOD OF PREPARING WOUND SURFACE FOR PEDICLE MUSCLE FLAP TRANSPLANTATION BY USING NEGATIVE PRESSURE SYSTEM Russian patent published in 2024 - IPC A61B17/00 A61F13/05 A61B17/322 A61M27/00 

FIELD: medicine; surgery.

SUBSTANCE: surgical treatment of wound defect surface and necrotomy are performed. Pedicle muscle flap is formed simultaneously. Medical fine-pored hypoallergenic sterile polyurethane sponge with a single-lumen drainage is placed in the area of the wound defect and around the muscular flap. Closed with a sealing bandage. Drainage is connected to a negative pressure apparatus with a negative pressure of 120 mmHg. Dressing is performed once every two days. After the mature granulation tissue is formed and the wound surface is cleaned, the wound defect is closed by moving the pedicle muscle flap into it. Wound bed and the displaced muscle flap are covered with a fine-pored hypoallergenic sterile polyurethane medical sponge with a single-lumen drainage.

EFFECT: method makes it possible to prepare a wound surface with gunshot fragmentation wounds of soft tissues for transplantation of a muscular flap on a pedicle, reduce the rate of infectious complications and improve the results of transplantation.
