Guide wire matched with minimally invasive dilatation drainage kit for use

Abstract

The invention relates to the technical field of medical instruments, and discloses a guide wire matched with a minimally invasive dilatation drainage kit for use, wherein the guide wire comprises a core wire, the surface of the core wire is fixedly sleeved with a winding wire, and the winding wire is specifically made of 304 stainless steel; by arranging the core wire and the winding wire which are made of 304 stainless steel, the hardness of the guide wire is increased; the situation that the guide wire is bent or deformed is avoided; the smoothness of the guide wire in the guide-in process is guaranteed; medical staff can guide an expansion tube and conduct operation positioning more easily; and then the guide wire is more suitable for application and popularization; the liquid extraction grooves are formed in the core wire and the head end, so that medical staff can extract hydrops through the liquid extraction grooves by using an injector; whether the guide wire reaches a drainage position or not is determined; the situation that the expansion tube needs to be pulled out and reinserted due to the wrong position of the guide wire is avoided; time is shortened; efficiency is improved; cost is reduced; and the purpose of assisting drainage is achieved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a minimally invasive dilation and drainage kit used with guide wires. Background technique [0002] The minimally invasive expansion and drainage kit is mainly composed of expansion sheath, extraction sheath and drainage tube. The expansion sheath is composed of tube body and plastic fittings. The extraction sheath is composed of tube body and plastic fittings. The drainage tube is composed of catheter, plastic fittings and connecting tube. , Various forms of expansion kits can be composed of a single or multiple sets. [0003] However, at present, the guide wires used clinically are ordinary stainless steel guide wires or nickel-titanium alloy guide wires. Its shortcoming is that the ordinary guide wire is soft during the dilation operation, and it is easy to complete the guide wire input process, and the friction caused by the dilation tube entering the process is e...
