Description

Guiding device is put into to drainage tube wicresoft Technical Field The utility model belongs to the technical field of medical instruments, and particularly relates to a guiding device for minimally invasive drainage tube placement. Background In surgery, wound bleeding and tissue fluid exudation are unavoidable problems, and if accumulated blood and accumulated fluid are retained in a body cavity or a tissue clearance, serious complications such as postoperative infection, delayed incision healing, limb necrosis and the like are easily caused. The negative pressure drainage tube is a core tool for leading wound blood and seepage out of the body, and is connected with an external negative pressure source through a tube body to form a pressure gradient to realize active drainage. The prior surgical negative pressure drainage tube is mainly divided into two types, namely a simple side hole drainage tube, a silica gel or PVC soft tube body, a channel which is required to be established by a surgical knife blade and a vascular clamp and then is placed, the problems of difficult puncture, additional instrument operation and large tissue cutting damage exist, and the other type is a drainage tube with a puncture guide needle, wherein a hard puncture guide needle is additionally arranged at the head end of the drainage tube to assist in puncture, and the guide needle is sheared after puncture, but the puncture guide needle of the scheme is required to puncture from the tissue gap to the outside of the skin, so that the operation is inconvenient and laborious.
