Abstract

The invention provides a construction device for the subcutaneous tunnel. The construction device comprises an inner puncture core, an obtuse expander and a tunnel supporting pipe. The inner puncturecore is used for puncturing the skin to form a puncture point; the obtuse expander movably sleeves the inner puncture core and is used for expanding the subcutaneous tissue along the puncture point toform the subcutaneous tunnel; the tunnel supporting pipe movably sleeves the obtuse expander and is used for supporting the interior of the subcutaneous tunnel to prevent a medical catheter from being bent under compression of the subcutaneous tissue. According to the construction device for the subcutaneous tunnel, by arranging the inner puncture core, the obtuse expander and the tunnel supporting pipe, when the construction device is used for constructing the subcutaneous tunnel, bleeding is reduced, the infection rate of wounds is low, and the medical catheter cannot be bent under compression of the subcutaneous tissue.

Description

technical field [0001] The invention belongs to the technical field of medicine, and more specifically relates to a subcutaneous tunnel construction device. Background technique [0002] In many clinical operations, after the medical tube is implanted, in order to reduce the chance of infection, a subcutaneous tunnel is usually created from the original puncture point to a point 3-5cm away from the periphery to close the original puncture point, thus making the The tube body is far away from the original puncture point. [0003] In the prior art, there are generally two methods for constructing subcutaneous tunnels: [0004] 1. Use surgical curved forceps to implement, and after reaching the pointed position, use a skin knife to break the skin to form a subcutaneous tunnel; [0005] 2. Use tunnel needles to implement, tunnel needles generally have a skin-breaking function. [0006] Both methods have the following disadvantages: [0007] 1. They are all made of metal surg...
