Ureteral stent tube and ureteral stent device applying same

Abstract

The invention discloses a ureteral stent tube and a ureteral stent device applying the same. The ureteral stent tube comprises a stent tube body and a pull wire, wherein the pull wire comprises an elastic section and a magnetic suction section. One end of the elastic section is fixedly connected with the tail of the stent tube body, the other end of the elastic section is fixedly connected with the magnetic suction section, the elastic section is an elastic silk thread, and the magnetic suction section is a silk thread with an intermittent iron wire. When the elastic section is freely unfolded, the length of the pull wire is smaller than that from the tail of the stent tube body to a urethral orifice of a patient after the ureteral stent tube is implanted into the body of the patient. When the ureteral stent tube is taken out, the magnetic suction section is outwardly attracted by a magnet, the elastic section is elongated, the pull wire is exposed out of the body, and the ureteral stent tube is taken out by pulling the pull wire. Compared with the prior art, the ureteral stent tube solves the problem that the patient is possibly infected after the exposed pull wire is contaminated, and also solves the problem that the patient feels uncomfortable as the pull wire is exposed.

Description

technical field [0001] The present invention relates to the field of medical equipment, more specifically, to a ureteral stent tube, and to a ureteral stent device using the above-mentioned stent tube. Background technique [0002] A ureteral stent is a medical device in the form of a long, thin tube. When the ureter is obstructed by stones, scar stenosis, tumor, etc., a ureteral stent can be implanted in the patient to support the ureter so that urine can drain from the kidney to the bladder. At the same time, ureteral surgery (including ureteroscopy, lithotripsy, and open ureteral surgery) and renal pelvis surgery (eg, pyelolithotomy, pelvis plasticity, percutaneous nephrolithotomy, etc.) routinely require placement of ureteral stents. At present, there is no ureteral stent that can be permanently placed in the body. After a period of use, it is necessary to remove the ureteral stent through an invasive operation, usually by cystoscopy. Although cystoscopic operation is ...
