SURGICAL ASSISTANCE DEVICE FOR SUTURELESS WOUND CLOSURE OF SKIN WOUNDS IN DEEP FASCIA OF LIMBS
Document Type and Number:
WIPO Patent Application WO/2020/186730
Kind Code:
A1
Abstract:
Provided is a surgical assistance device for sutureless wound closure of skin wounds in deep fascia of limbs, comprising a subcutaneous negative-pressure drainage apparatus (1), a wound closure apparatus (2), a supracutaneous negative-pressure apparatus (3), and a plurality of drainage needles (4). The plurality of drainage needles (4) drain the accumulated liquid in subcutaneous soft tissue, thereby ensuring that the accumulated liquid in the subcutaneous soft tissue can be expelled promptly; the wound closure apparatus (2) squeezes the edge of the skin and, forced by the subcutaneous negative-pressure drainage apparatus (1), causes the inner cavity of the subcutaneous wound to remain closed during the healing and rehabilitation process; the subcutaneous negative-pressure drainage apparatus (1) delivers liquid medicine to the subcutaneous wound while simultaneously draining the accumulated liquid in the inner cavity of the subcutaneous wound, ensuring that the environment of the inner cavity of the subcutaneous wound is maintained in a state conducive to wound recovery; furthermore, the supracutaneous negative-pressure apparatus (3) can generate a force by means of the action of the negative pressure, causing the position of the tissue of the skin wound and peripheral area thereof to be maintained in a stable state, and in turn, achieving the objective of sutureless closure of the skin wound.
