Abstract
The utility model relates to a ureteral stent withdrawing device, which comprises a No. Fr14 urinary catheter, wherein the head end of the urinary catheter is provided with an opening; the tail part of the urinary catheter inner core is provided with scales, the front end of the inner core is slightly bent, and the tip part has strong magnetism. The inner core extends into the bladder through the ureter, and the magnetic ureter stent is pulled out by utilizing the magnetic attraction. The utility model is stably connected with the magnetic tail end of the ureteral stent tube through the magnetic device to extract the stent tube, anesthesia is not needed, a cystoscope is not needed, the operation is convenient and time-saving, the pain and the cost of a patient are reduced, and the risk of cross infection is reduced by using disposable materials.
Description
Technical Field
The utility model belongs to the technical field of medical treatment, and particularly relates to a ureteral stent extractor and a using method thereof.
Background
The ureteral stent is a catheter which is left in a ureter for draining urine and preventing ureteral stenosis. The two ends of the tube are bent into a ring shape similar to English letter J and are called as a double J tube, one end of the tube is placed in the renal pelvis, and the other end is left in the bladder. After a period of time of retention, it is removed from the body. The traditional tube taking method is characterized in that the lithotomy position is taken on an operating bed, the lithotomy position enters a bladder through a rigid cystoscope through a urethra and is directly viewed, the tail ends of two J-shaped tubes of the forceps are clamped and pulled out, so that the pain of a patient (particularly a male patient) is increased, the urinary tract stimulation symptom is easy to appear after the tube is pulled out, partial patients are injured by the urethra to appear hematuria, anesthesia is needed, the cost is high, the operation is relatively time-consuming, and the soft cystoscope can relieve the pain, but is expensive and difficult to popularize. Therefore, the ureteral stent extractor which is simple to operate, needs no anesthesia, is low in cost and has little damage to patients is urgently needed clinically, and tube drawing can be completed in a dressing room.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides the ureteral stent extractor which can relieve the pain of a patient, is simple to operate, does not need anesthesia and has low cost and a using method thereof.
In order to solve the technical problems, the utility model adopts the technical scheme that: a ureteral stent extractor comprises a ureter and a ureter inner core. The head end of the ureter is open. The tail part of the inner core of the ureter is provided with scales, the front end of the inner core is slightly bent, and the tip part is a concave surface and has strong magnetism. The inner core extends into the bladder through the ureter, the concave magnetic tail end of the ureter inner core and the convex magnetic tail end of the ureter stent are mutually attracted and stably connected together, and the inner core is pulled out from the ureter to take out the ureter stent.
The ureter be the latex material, the texture is soft, the surface is smooth, the pointed end is uncovered.
The ureter inner core be the silica gel material, the texture is soft, the head end is 1/4 radians bending, the pointed end is the concave surface, has the strong magnetism.
The utility model has the advantages that:
1. the ureteral stent extractor provided by the utility model selects the latex ureter and the silica gel inner core, does not need a cystoscope and anesthesia, and is low in material price.
2. The ureteral stent extractor provided by the utility model is simple to operate, causes little pain to patients, and has a wide application prospect in urology surgery.
3. The tip of the ureter inner core has strong magnetism, the silica gel material is good in flexibility, and the irritation to urethra and bladder mucosa is small in the operation process, so that the ureter stent can be taken out conveniently.

Fig. 2 is a schematic structural diagram of the inner core of the ureter.
Detailed Description
As shown in figures 1-2, the ureteral stent extractor comprises a ureter 1 and a ureter inner core 2. The length of the urinary tube is 30cm, the diameter is F14, the tip of the urinary tube is blunt and round, the opening is 3, the caliber is F8, the opening is communicated with the diversion channel 4, the urinary tube air bag 5 is arranged 1cm near the opening, and the air bag is communicated with the inflation channel 6. The length of the inner core of the ureter is 40cm, the diameter is F7, the ferromagnetic tip 7 is a concave surface 8, the length of the magnetic part is 0.5cm, the depth of the concave surface is 3mm, the ureter stent is favorably connected with the tail end convex surface of the ureter stent, the head end is bent 9 with the radian of 1/4, the length of the bent part is 3cm, the tail end 10 is provided with 10cm long scales, and the scale interval is 1 cm.
When the ureteral stent is pulled out, the ureteral catheter 1 needs to be inserted into a bladder through a urethra, 10ml of air or normal saline is injected into the air bag 5 into the inflation channel 6, the ureteral catheter 1 is pulled backwards, the air bag 5 is positioned at an inner opening of the urethra, and urine in the bladder can be drained outwards through the flow guide channel 4 through the opening 3 at the tip of the ureteral catheter. The bladder is slightly inflated by injecting 50mL of sterile physiological saline into the bladder through the diversion channel 4. The ureteral stent is inserted into the ureteral inner core 2 through the ureteral diversion channel 4, the tail section is remained by 7cm, the 1/4 radian bend 9 at the head end extends out of the tip end of the ureteral catheter, then the inner core 2 is slowly rotated clockwise, the strong magnetic tip 7 at the concave surface of the inner core and the strong magnetic tail end of the convex surface of the ureteral stent are attracted, then the ureteral inner core is pulled backwards, the ureteral stent can be together pulled out, and finally the ureteral catheter is pulled out.
The ureteral stent extractor selects the latex ureteral 1 and the ureteral inner core 2, does not need a cystoscope or anesthesia, has low material price, good flexibility, small irritation to urethra and bladder, no damage, simple operation and wide application prospect in urology surgery.
The above description is only a preferred embodiment of the present invention, and it is understood that those skilled in the art may make various modifications and additions without departing from the method of the present invention, and such modifications and additions are to be regarded as the scope of the present invention.
