Surgical auxiliary equipment for closing skin wound in superficial fascia of skin without suture

Abstract

The invention discloses surgical auxiliary equipment for closing a skin wound in superficial fascia of skin without a suture. The surgical auxiliary equipment comprises a subcutaneous negative pressure drainage device, a wound closing device and an epitrichial negative pressure device, wherein the subcutaneous negative pressure drainage device comprises a catheter which partially extends into an inner cavity of subcutaneous wound by a preset depth and is used for generating negative pressure to close the inner cavity of the subcutaneous wound in a healing process; the wound closing device is arranged on the peripheral side of the skin wound and is used for extruding the skin edge to keep the skin wound in a closed state in the healing process; and the epitrichial negative pressure device is arranged on the periphery of the skin wound and is used for generating negative pressure to maintain the stability of the tissue positions of the skin wound and the peripheral area of the skin wound. According to the surgical auxiliary equipment, suture-free closing of the whole-layer tissues above the deep fascia of the skin can be realized, transverse scars caused by suture compression / cuttingon the surface of the skin are avoided, and no suture knot is left in the superficial fascia, so that important factors causing bacterial colonization and main inducements of recurrence of incision infection are eliminated.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a surgical auxiliary device for closing skin wounds without sutures in superficial skin fascia. Background technique [0002] As we all know, humans have gradually lost the ability to regenerate the body during the evolution process, and the tissue damage caused by trauma mainly depends on scar healing. Therefore, there is a close relationship between surgical suture and tissue healing, and the quality of suture can determine the quality of tissue healing to a certain extent. Surgical sutures usually use a curved needle to carry the suture through the severed tissue, and then tighten and fix the suture by knotting, so that the severed tissue can fit tightly, thereby creating favorable conditions for healing. An ideal surgical suture should meet the requirements of moderate tension, good incision edge fit, no dead space, and no permanent or only a small amount of suture m...
