Background

In the clinical treatment process of the trauma repair surgery, local soft tissue defects are often seen, and the wound surface can not be repaired in a closed manner under the surrounding conditions, at the moment, the wound surface must be repaired in a closed manner by using a distant metastasis pedicle tissue flap. After the skin flap is transferred to cover the wound surface, blood circulation is gradually established with the wound surface substrate and the surrounding tissues, the required time is generally 2-3 weeks, and then the blood supply from the pedicle of the skin flap must be blocked, so that the transferred skin flap survives through the blood circulation established by the wound surface substrate and the surrounding tissues. Finally, the pedicle of the flap is separated, the tissue is transferred to survive, and the wound surface is repaired.

Among them, the skin flap blood flow blocking exercise is very critical, which determines the success or failure of the entire treatment regimen. The current method for exercising the blood flow blockage of the pedicles of the skin flaps comprises the following steps: the blood flow is blocked by clamping with medical vascular forceps or intestinal forceps. However, clamping with a medical vascular clamp or intestinal clamp to block blood flow has the following drawbacks: 1. the pedicel pain is serious in the exercise process, patients often cannot tolerate the pedicel pain, and analgesics are required to be applied; 2. the operation process is relatively complex and needs doctors with abundant experience to operate; 3. the skin flap has not established blood circulation with the base of the wound surface and the surrounding tissues, and the blood circulation of the pedicles is blocked prematurely, so that partial or even all tissues are necrotized, and the surgical treatment effect is poor.
