Description
Technical field:
The present invention relates to medical apparatus and instruments, be meant a kind of multi-cavity high-pressure water-bag posterior urethral expanding catheter medical apparatus and instruments that hyperplasia of prostate is used for the treatment of.
Background technology:
Hyperplasia of prostate is the multiple disease of elderly men, is tormenting the latter half of one's life of elderly men.The way that is used for the treatment of hyperplasia of prostate at present has: slight Drug therapy; Weight person's open surgery excision, or per urethra TURP, gasification; Also have physics heating therapy such as microwave, radio frequency, laser, focus ultrasonic, way is operation, TURP, gasification more completely, but to the aged at weak and sickly advanced age, not anti-operator, inconvenience is implemented, and operation bring painful many, complication is many, have a big risk.Other physics thermotherapy treatment weak effect, general only the adaptation, slightly increase the survivor.Over one hundred year historical prostate expansion interventional therapy arranged, be based on and do not excise body of gland and adopt crack valve-type or gasbag-type to carry out urethral dilatation, but because of the back urethral obstruction mechanism that prostatic hyperplasia caused is lacked more deep theoretic discussion and medical practice, thereby lack theoretic clear understanding, cause technical progress very slow, practical external sacculus dilating catheter and domestic metal tube hidden balloon dilator just appearred until the 1980s, and other air bag, the water balloon dilator conduit, but all there is open defect, this mainly is to think that because of the traditional theory that is had big mistaken ideas the back membranous part of urethra is a control urine " valve ", the constraint of expansion forbidden zone, air bag is short and small, and length is no more than 4cm, and swell diameter is 2.5cm only, only be confined to the hypertrophy gland division is expanded, only adapt to patients with mild,, and do not expand membranous part again because of slight expansion easily bounces back, so therapeutic effect is poor, very fast easy recurrence, above-mentioned expansion is invalid to severe hypertrophy person, classifies as and prohibits the indication person.
Chinese patent literature ZL99247798.0 discloses a kind of composited high pressure water capsule prostate expansion and has split series of conduits, in A type conduit wherein is, outer two capsule dilator, this is to domestic and international prior art, particularly to the bigger improvement of the inventor's the dilator of monolayer formerly technology, particularly be in isometrical pair of capsule part of high pressure water pocket back segment, high strength and deformation after the pressurising, effective expansion that tough and tensile membranous part can acquire a certain degree is split, the successful implementation of this A type conduit, clinical thousands of routine high curative rate, thoroughly abolished the error theory viewpoint of membranous part ' forbidden zone ', proved and expanded the most important property of splitting membranous part.Simultaneously, practice process has proved that also the thin two ductus bursaes in thick back still have weak point before this A type: the one,, to expand its swell diameter of conduit back segment of splitting membranous part still less than normal, the maximum swelling diameter is 3cm, the membranous part expansion is split not in place, its long-term effect, membranous part blocks for being able to thorough releasing, the 2nd, although, need to expand the gland division that splits and be in the two capsule parts of conduit, but be in the not equal-diameter part that capsula interna is thin, external capsule is thick, it is yielding that pressurized is split in the particle size external capsule expansion of monolayer, so part only is equivalent to the monolayer capsule basically and expands and to split effect, gland division expanded to split effect not ideal enough.
Summary of the invention:
Problem to be solved by this invention is, expand in whole process and to split the back urethra, thoroughly get rid of back urethral obstruction and forming on the understanding basis of new row, control urine mechanism, deficiency at the two ductus bursaes of prior art A type, it is given bigger improvement, a kind of multi-cavity high-pressure water-bag posterior urethral expanding catheter that hyperplasia of prostate is used for the treatment of is provided, can effectively implement the back membranous part of urethra, body of gland and peplos, neck finish portion expansion are split and put in place, reach the remarkable result of interventional minimally-invasive treatment hyperplasia of prostate.
Technical scheme of the present invention: a kind ofly treat the multi-cavity high-pressure water-bag posterior urethral expanding catheter that hyperplasia of prostate is used, it has the urethral catheterization lumen of comprising 2, inner high voltage water pocket water-filling tube chamber 3, the software multi-cavity catheter 1 of outer high pressure water pocket charging pipe chamber 4 and flushing tube chamber 5, with its head, tail two ends are fixed in the high pressure water pocket 6 on the multi-cavity catheter outer wall, described high pressure water pocket 6 is made of outer high pressure water pocket 7 and the 8 pairs of capsules of inner high voltage water pocket that are wrapped in it, the inner high voltage water pocket is positioned at outer high pressure water pocket section afterwards, inner high voltage water pocket water-filling tube chamber 3 is established opening 9 in the inner high voltage water pocket, opening 10 is established in outer high pressure water pocket charging pipe chamber 4 in outer high pressure water pocket, the present invention's invention main points are, high pressure water pocket 6 front and back section swell diameters equate that the back integral body that expands is equal diameter like cylinder; Its length is, places inside and outside its tail end of high pressure water pocket that puts in place to stride across membranous part and part bulb in the operation, and its head end of inner high voltage water pocket is butted on bladder neck, and outer its head end of high pressure water pocket probes into bladder through eck.Its preferred parameter scope: the long 3-8cm of inner high voltage water pocket, the long 7-12cm of outer high pressure water pocket; Inside and outside high pressure water pocket swell diameter is 2-4.4cm.
The advantage of this multi-cavity high-pressure water-bag posterior urethral expanding catheter is, membranous part is expanded split, interlobar fissure is opened body of gland, peplos splits, eck is expanded, particularly effective expansion of the control urine ' membranous part forbidden zone ' that is subjected to traditional theory constraint is split, remove blocking of its tough and tensile membranous part, real accessory has outstanding substantive distinguishing features and obvious improvement.Make the urethra that bend by pressure distortion inner chamber narrows down and go up and prominently raise neck of bladder oral area that morpheme changes and expanded and split, correct and recover.Outgrowth body of gland splits the nervus vasculairs damage that causes because of expansion, can make the atrophy gradually of its body of gland, and no longer recurrence makes omnidistance back urethra be in the unobstructed state of low pressure low-resistance.This conduit high pressure water pocket is an inside and outside pair of capsule structure, its case hardness, deflection and pliability meet back urethra physiological feature and treatment requirement, easy to operate, the cure rate height, therapeutic effect is good, do not have recurrence in 3 years, effective percentage was higher than more than 80% in 5 years, be adapted to light, in, all prostatic hyperplasia patients of severe.
Treatment mechanism of the present invention can be sketched and be: symptoms such as the caused urine wait of hyperplasia of prostate, frequent micturition, weak stream of urine, urine pool stream all because of prostatic hyperplasia cause bladder, back urethra pressure rule change unbalance due to, the not outgrowth normal person of body of gland, during anuria, by bladder, eck, body of gland urethra to membranous part, thereby its pressure curve is urethra presses high bladder to force down taboo urine, and as urine meaning when urinating, detrusor of bladder shrinks, the smooth muscle of eck urethra, gland portion and membranous part and sphincter then diastole are lax, and its pressure curve is bladder and presses high urethra to force down and urinate.When prostatic hyperplasia, because the particularly hypertrophy of substrate and the formation of pseudocapsule of body of gland, the binding force of true and false peplos strengthens, urethra must be oppressed and twist to the body of gland that expands, it is high to cause the gland division urethra to be pressed, simultaneously, because of body of gland polyploid hypertrophy is expanded, its tip must form extruding and stretching to membranous part, cause the membranous urethra pressure anomaly to increase, be high resistant high pressure systolic and diastolic function imbalance state, and when the body of gland middle lobe hyperplasia, prominent in bladder neck will be elevated, deformation, the angle of urinating changes, forming the eck high pressure blocks, so form membranous part, body of gland, eck three-hypers press belt, the pressure curve generation ANOMALOUS VARIATIONS of urinating causes back urethra high pressure to be urinated and blocks.Adding the age again increases, the neuromodulation hypofunction, detrusor urinate for a long time get involved, aging function loses compensatory, and cause the compensatory plumpness of wall of urinary bladder smooth muscle again, cause bladder acraturesis hypotony, so form source low pressure, back urethra high pressure makes the difficulty of being obstructed of urinating.Above-mentioned explanation, urethra after membranous part, body of gland and peplos, the neck finish portion whole process fully expanded split, remove the three-hypers press belt, realize back urethra low pressure low resistive state, forming new pressure balance row, control urine mechanism with source bladder low pressure, is not all right body of gland excision and can treat the effective ways of hyperplasia of prostate.A large amount of clinical practice prove, traditional theory membranous part control urine " forbidden zone " has big mistaken ideas, urinary continence is real in being mainly to comprise that back urethra integral body is finished jointly more than the membranous part by membranous part, adopt the present invention to implement expansion and split membranous part, can grasp and accomplish fully and both expand cracking, not cause urinary incontinence again except that blocking.So say and adopt urethra dilator behind this high pressure water pocket, be not implement opening or the produce effects of operative treatment hyperplasia of prostates such as urethra TURP, gasification, correct medical apparatus and instruments and method.
