Abstract
The utility model relates to an urethroscope passage sheath composed of a resin passage, an air passage and an air bag which are made from prearranged elastic materials, wherein the air passage is arranged in the resin passage and is communicated with the air bag outside the resin passage by an opening on the wall of the front end of the resin passage; the rear end of the air passage penetrates out of the wall of the resin passage, and a plug is arranged at the tail end. When in use, the utility model is placed into a urethra and the air bag is inflated to expand and to prevent the utility model from sliding out; then, the urethroscope is operated. Thus, the utility model avoids urethra damage caused by the urethroscope and urethra stricture caused by the urethra damage.
Description
Technical field
This utility model relates to a kind of medical and clinical medical equipment, especially a kind of ureteroscope passage sheath that cooperates ureteroscope to use.
Background technology
Ureteroscope application and clinical diagnosis and treatment ureter and kidney disease are more and more widely, the rigid ureteroscope of clinical practice accounts for very most of, because ureteroscope must pass through urethra, the female patients urethra is shorter, the probability of the damage in operating process is lower, but the andropathy human urethra is longer, push-and-pull back and forth in ureteroscope operation moving process, cause injury of urethra easily, report is all arranged both at home and abroad.According to our statistics, ureteroscope operation damage urethra causes that narrow incidence rate is 5-7% after the injury of urethra, and wherein the male is in the great majority.Before this, have human cystoscope epitheca to use as the passage sheath, exist big shortcoming, because of the cystoscope epitheca is rigid metal material, as being moved, friction can damage urethra in urethra.In addition, ureteroscope moves around in the cystoscope epitheca, and the mutual friction of two kinds of rigid thing phases can make the ureteroscope surface trace that rubs occur, and this trace that rubs can damage ureter wall after inserting ureter, causes narrow behind the injury of ureter, is not desirable method.Urethral stricture needs treatment once more, brings misery to patient, has increased financial burden simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of ureteroscope passage sheath made from the resin material of predetermined elasticity, reaches the purpose of using ureteroscope safely, avoiding damaging urethra.
The technical scheme that its technical problem that solves this utility model adopts is: design a kind of ureteroscope passage sheath, be made up of the gentle body passage of the resin pipeline of the long 150-300mm that makes with the material of predetermined elasticity, outer perimeter 26mm, interior girth 15mm, air bag; Wherein, gas passage is built in the resin pipeline, and the air bag outer by opening on the resin pipeline front tube wall and resin pipeline communicates, and the rear end of gas passage passes the tube wall of resin pipeline, and end is provided with pipe close.The material of described predetermined elasticity is that the resin material of predetermined elasticity, particularly medical grade silicon rubber are best; Air bag can be formed by being enclosed within the outer elasticity short tube of resin pipeline and the sealing hoop at two ends; Also can be that the elasticity short tube that is sealed in the pitch tube pipeline outer wall is cohered at two ends, this ureteroscope passage sheath can be according to the length difference of men and women's urethra, can make the 150-200mm length of female patient special use, male patient 250-300mm length is the best to make the long unisex type of 280mm.During use, product of the present invention is placed in the urethra, and stifled upward pipe close after making it to expand for the air bag qi of chong channel ascending adversely, in case ureteroscope passage sheath skids off, carry out the ureteroscope operation then.
The ureteroscope passage sheath that this utility model provides, owing to adopt the material of predetermined elasticity, particularly the medical grade silicon rubber material is made, even inserting urethra moves very little to the probability of injury of urethra, ureteroscope moves in this passage sheath, hard soft thing contact, can not cause the ureteroscope surface trace that rubs to occur, avoided the generation of the injury of ureter that this reason causes, through clinic trial 36 routine patients, narrow after none example generation injury of urethra, illustrate that this passage sheath has very high use value, has the prospect of promoting the use of.
Through the domestic 4 tame front three Urology Surgery clinical practice 36 routine patients of hospital, the result is as follows:
Patient's number: 36 examples, wherein male 29 examples, women 7 examples, 33.5 years old mean age.
Diagnosis: ureteral calculus 31 examples, hematuria 5 examples.
Clinical practice: all capable Ureteroscopy of this group case and treatment, in the ureteroscope operating process, use this ureteroscope passage sheath protection urethra.Operating time: reach 110 minutes most, the shortest 82 minutes.The result: check end of operation, extract the passage sheath again after extracting ureteroscope, equal indwelling catheters not, the whole cases of postoperative are urinated all right, the situation of dysuria and urine retention do not occur.Postoperative does not have 1 example paruria takes place with examining for 4 weeks.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
