Surgical auxiliary equipment for closing skin wounds in deep fascia of four limbs in seamless mode

Abstract

The invention discloses surgical auxiliary equipment for closing skin wounds in deep fascia of four limbs in a seamless mode. The surgical auxiliary equipment comprises a subcutaneous negative pressure drainage device, a wound closing device, an epithelial negative pressure device and a plurality of drainage needles, and is used for draining effusion in subcutaneous soft tissue through the drainage needles, so that the effusion in the subcutaneous soft tissue can be discharged in time; and besides, the skin edge is extruded through the wound closing device, a subcutaneous wound inner cavity iskept in a closed state in the healing and rehabilitation process under the force of the subcutaneous negative pressure drainage device, and the subcutaneous negative pressure drainage device can convey liquid medicines to the subcutaneous wound inner cavity while draining the effusion in the subcutaneous wound inner cavity. The environment of an inner cavity of the subcutaneous wound is kept in astate beneficial for wound recovery. Moreover, the epithelial negative pressure device can generate acting force through the negative pressure effect, so that the tissue positions and the peripheralarea of the skin wound are kept in a stable state, and then the purpose of closing the skin wound in a seamless mode is achieved.

Description

Technical field[0001]The application relates to the field of medical devices, and in particular to a surgical auxiliary device for closing skin wounds without sutures in the deep fascia of extremities.Background technique[0002]As we all know, humans have gradually lost the ability to regenerate the body in the process of evolution. The main response to tissue damage caused by trauma is scar healing. Therefore, there is a close relationship between surgical suture and tissue healing. To a certain extent, the quality of suture can determine the quality of tissue healing. Surgical sutures usually use curved needles to carry sutures through the broken tissues, and then tighten and fix the sutures by knotting, so that the broken tissues fit closely, thereby creating favorable conditions for healing. The ideal surgical suture should meet the requirements of moderate tension, good incision edge alignment, no dead space, no permanent or only a few suture marks.[0003]Closing skin cracks by s...
