Abstract：Objective To design a new type of skin external stretch device which can be applied to VSD negative pressure
simultaneously for irregular large wound surface. Methods We used strong suture to stretch the wound instead of metal peaches and
kirschner-wire, then shortened the suture which could be connected to the new skin stretch device gradually to achieve the purpose of
the closure of the wound. Results A new skin external stretch device was designed and obtained, which was not limited by the shape
and size of the wound. The external skin pulling device of VSD dressing device could be applied simultaneously. In addition, the
national patent was obtained. Conclusion The skin drawer based on the principle of gradually shortening the suture can achieve the
purpose of pulling the skin closed wound surface, which is more advantageous than other skin traction devices.
