Problems solved by technology

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

Embodiment Construction

[0013] Such as Figure 1-2 As shown, the ureteral stent extractor of the present invention includes a urinary catheter 1 and a urinary catheter inner core 2 . The urinary catheter is 30cm long and F14 in diameter. The tip of the urinary catheter is round and has an opening 3 with a diameter of F8. The inner core of the ureter is 40cm long, the diameter is F7, the strong magnetic tip 7 is concave 8, the magnetic part is 0.5cm long, and the concave surface is 3mm deep, which is conducive to connecting with the convex surface of the end of the ureteral stent tube. The head end is bent in a 1 / 4 arc 9 and the curved part is 3cm long , the tail end 10 has a 10cm long scale, and the scale interval is 1cm.

[0014] In the present invention, when pulling out the ureteral stent tube, the urinary catheter 1 needs to be inserted into the bladder through the urethra, and then 10ml of air or normal saline is injected into the air bag 5 into the inflatable channel 6 to inflate the air bag, ...

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...
