Magnetic ureteral stent tube extractor

Abstract

The invention relates to a ureteral stent tube extractor which comprises an Fr14 urinary catheter, and the head end of the urinary catheter is provided with an opening; The front end of the urinary catheter inner core with graduated tail is slightly bent, and the tip of the urinary catheter inner core has strong magnetism; and the inner core extends into the bladder through the urinary catheter, and a magnetic ureteral stent tube is pulled out through magnetic attraction. The magnetic device is stably connected with the magnetic tail end of the ureteral stent tube to pull out the stent tube, anesthesia is not needed, a cystoscope is not needed, operation is convenient and time-saving, pain and cost of a patient are reduced, and the cross infection risk is reduced through disposable materials.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a ureteral stent tube extractor and a using method thereof. Background technique [0002] A ureteral stent is a catheter placed in the ureter to drain urine and prevent ureteral stricture. Its two ends are curved and ring-shaped like the English letter J, also known as double J tube, one end is put into the renal pelvis, and the other end is indwelling in the bladder. After a period of time, it needs to be removed from the body. The traditional tube removal needs to take the lithotomy position on the operating bed, pass the rigid cystoscope through the urethra into the bladder, and clamp the end of the double "J" tube under direct vision. Irritation symptoms, some patients have hematuria due to urethral injury, and require anesthesia, the cost is high, and the operation is relatively time-consuming. Although flexible cystoscopy can relieve pain, it is expensive and...

The traditional tube removal needs to take the lithotomy position on the operating bed, pass the rigid cystoscope through the urethra into the bladder, and clamp the end of the double "J" tube under direct vision. Irritation symptoms, some patients have hematuria due to urethral injury, and require anesthesia, the cost is high, and the operation is relatively time-consuming. Although flexible cystoscopy can relieve pain, it is expensive and difficult to popularize
