Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of Ureteral stent tube noinvasive pipe extractor.
Background technology
Existing Ureteral stent tube pipe drawing device all is to insert under the intravesical direct-view by rigid cystoscope per urethra to pull out Ureteral stent tube by foreign body forceps.
Rigid cystoscope is metallicity endoscope, mirror sheath specification Fr17-24 (the about 2.71-3.82cm of radius r), in pulling out the Ureteral stent tube process, the patient gets calculi position, the per urethra topical anesthesia, the direct-view per urethra is inserted intravesical under the guide of cold light source, confirms to use foreign body forceps to pull out the inner support pipe behind the Ureteral stent tube position.But adopt metallicity endoscope to have following shortcoming: special posture requires to cause many gerontal patients or the rational patient of change of coxarthropathy to cooperate difficulty; Metallic foreign body is inserted and is caused pain, though per urethra surface anesthesia before the art, because the cystoscope caliber is thicker, the expansion of being forced to property of urethra is obvious, and the pain that causes thus can't effectively be alleviated; Because of physiology or pathologic factors such as patient's urethral stricture, foreign body obstruction, prostatic hyperplasia, deformity of urethras, cause the cystoscope visual field unclear, insert difficulty, via damage, urethra perforation, the secondary damage of the operation such as mucous membrane of urethra avulsion; Insert in the process at cystoscope, the mirror sheath causes the damage of the repressive ischemia of mucous membrane of urethra and mucous membrane of urethra, thereby causes mucosal bleeding serious in the art or the generation of the complication such as the urinary system infection of severe postoperative, urethral stricture; May cause the damage of mucous membrane of urinary bladder on every side in the foreign body forceps gripping endoureteral stent process in the art; In order to keep the visual area clear, need to pour into about 200ml normal saline through cystoscope to urethra and intravesical in the art, cause the strong irritation sign of bladder of patient to be difficult to cooperate, thereby increased operating difficulty and art risk; The misery that causes in preparation and the tube drawing process before the complicated art causes the strong anxiety of patient; Cystoscope is costly, disinfects the process complexity.
In addition, also have research that Ureteral stent tube is designed to Biodegradable material, the several months degrades voluntarily after Ureteral stent tube is inserted, and need not manually to pull out.But this technical scheme has following shortcoming: the uncertainty of degraded position causes the transposition of ureter rack tube stub, can cause lasting iatrogenic renal colic in the renal pelvis as moving on the stub, deviate to affect the trigone of urinary bladder to intravesical and can cause obvious irritation sign of bladder such as stub; The uncertainty of degraded time started causes Ureteral stent tube to support and the urine drainage effect by the good effective ureter of performance within the time that requires; The persistence of the degradation process fragment that causes coming off serves as the formation that core causes urinary system calculus in urine; The relatively poor controllability of degradation process causes local mucous membrane of ureter Ischemia Time long, causes that easily stricture of ureter affects one-sided renal function; Residual fragment stops up support tube or ureter easily in the degradation process, causes urine drainage to be obstructed, and damages one-sided renal function, is unfavorable for simultaneously the ureteral recovery of pathological changes side; Catabolite may cause the pathologic impact to ureter, bladder or mucous membrane of urethra, causes the generation of urinary system aseptic inflammation or tumor; Degradable material is costly.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly supports that noinvasive is inserted, the intravesical perfusion less, to patient body position's no requirement (NR), safe, generation and the low Ureteral stent tube noinvasive pipe extractor of use cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Ureteral stent tube noinvasive pipe extractor; comprise and adopt rubber to make and protection sheath in a tubular form; one end of described protection sheath is provided with draining hole and air bag inflation inlet; but the other end of described protection sheath is provided with charge-discharge air bag; side opening and support tube location fish mouth groove; be provided with the wire guide tube chamber that is arranged in parallel along the protection sheath in the described protection sheath; described protection sheath is provided with the through hole that is communicated with the wire guide tube chamber by the sidepiece of an end of support tube location fish mouth groove; be provided with the ultrasonic visible wire guide for sheathed support tube in the described wire guide tube chamber; stretch out outside the wire guide tube chamber end of described ultrasonic visible wire guide, and the opposite side of walking around support tube location fish mouth groove and being fixed in support tube location fish mouth groove is freely stretched out in another end of described ultrasonic visible wire guide from the through hole of support tube location fish mouth groove one side.
As further improvement in the technical proposal:
Be provided with the inflation piston in the described airbag aeration mouth.
Comprise also that be used to the operation capstan winch of taking in ultrasonic visible wire guide described ultrasonic visible wire guide stretches out in the outer end of draining hole and is wound on the described operation capstan winch, described operation capstan winch is provided with the operating grip for the rotating operation capstan winch.
The length of described protection sheath is 44cm, and the diameter of described protection sheath is 0.8cm, and the thickness of described protection sheath is 0.3cm.
