Embodiment Construction

[0014] see figure 1 , The retrievable biliary stent 1 of the present invention includes a stent body 2 , and it also includes a wire 3 connected to the stent body 2 . The stent main body 2 is in a spiral shape, and the proximal end of the stent main body is provided with an external thread 4, and the distal end of the wire is provided with an internal thread, and the wire and the stent main body are connected by threads. Since the threaded interface 4 is used to connect the wire and the main body of the bracket, the guide wire can be easily removed or assembled in the body directly through the endoscope.

[0015] see figure 2 , the special drainage tube for recoverable biliary stent of the present invention includes a drainage tube body 5, and the drainage tube body 5 includes a guide wire cavity 6 and a guide wire cavity 7 for a recoverable biliary stent; 8 communicates with the biliary tract for the guide wire to enter and exit; the side of the guide wire cavity is also p...

Abstract

The invention discloses a recyclable biliary stent. The biliary stent comprises a stent main body, and a lead wire connected with the stent main body, wherein the stent main body is of a spiral shape; an external thread is arranged at the near end of the stent main body, and an internal thread is arranged at the far end of the lead wire; and the lead wire and the stent main body are in threaded connection. The stent main body is of a spiral shape, and is connected with the lead wire, so that the stent main body can be taken out conveniently through the lead wire extending outside a human body.

Description

technical field [0001] The invention relates to a biliary tract stent, in particular to a recoverable biliary tract stent. Background technique [0002] At present, the biliary stent implanted in the human biliary tract needs to be taken out cumbersomely, and often cannot be taken out smoothly in one operation, causing great trauma to the patient and easily having a negative impact on the patient's psychology. In addition, during the drainage process with the drainage tube and the biliary stent, the patient will worry about the drainage tube prolapse, and feel annoyed by the inconvenience of daily life, personal cleaning, and skin pain around the tube caused by the traction of the tube, which will cause the patient to feel anxious, nervous, and bored. Contents of the invention [0003] Aiming at the shortcomings of the prior art, the purpose of the present invention is to provide a recoverable biliary stent that can be easily taken out from the body. [0004] In order to ...
