Problems solved by technology

At the same time, the collection system is not directly connected to the outside world, which can avoid bleeding and infection caused by nephrostomy; because there is no restriction and discomfort of the external drainage tube, the patient can get out of bed early, which is beneficial to postoperative recovery. In the middle, because the ureter is not a straight line, the catheter is prone to discount and blockage

Embodiment Construction

[0014] refer to figure 1 , figure 2 , figure 1 , figure 2 It is a structural schematic diagram of a specific embodiment of the present invention. As shown in the figure, the anti-bending pigtail catheter includes a catheter body, and the catheter body includes a catheter body 1 and a guide wire that passes through the catheter body 1. The guide wire includes a core wire 2 and a winding sleeve 3. The catheter body 1 is made of a plastic material with shape memory such as medical silicone material, and the winding sleeve 3 is formed by stacked helical winding wires. The core wire 2 is made of a shape memory material such as nickel-titanium alloy, so that the core wire 2 can still maintain a better original state after being bent many times, reducing the resistance when the guide wire passes through or is pulled out, and reduces the impact on blood vessels. and damage to human tissue, reducing the pain of patients, and through the helical winding sleeve 3, the catheter can s...

Abstract

The invention discloses an anti-bending pigtail conduit which comprises a conduit body. The conduit body comprises a conduit tubular body and a guide wire penetrating into the conduit tubular body, wherein the guide wire comprises a core wire and a wire winding sleeve, the conduit tubular body is made of a plastic material having shape memory performance, the wire winding sleeve is formed by spiral wrapping wires arranged in a superposed mode, the core wire is made from a shape memory material so that the core wire can be still kept in a good original state after being bent for multiple times, the conduit can be still kept to be in a conducting state through the spiral wire winding sleeve under the bending situation, and medical negligence is prevented.

Description

technical field [0001] The invention relates to an anti-bending pigtail catheter used in clinical medicine. Background technique [0002] Pigtail catheter, named for its curled ends, each end resembling a pig's tail. Due to its stent and internal drainage function, it can relieve temporary obstruction caused by ureteral inflammation and edema, and prevent postoperative wound leakage and ureteral stricture. At the same time, the collection system is not directly connected to the outside world, which can avoid bleeding and infection caused by nephrostomy; because there is no restriction and discomfort of the external drainage tube, the patient can get out of bed early, which is beneficial to postoperative recovery. In the middle, because the ureter is not a straight line, the catheter is prone to fold and blockage. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an anti-bending pigtail catheter. [0004] Th...
