Abstract
A urethral dilator is a device for dilating narrow sections of urethral stricture and suitable for self urethral dilating by male patients to treat urethral stricture. The urethral dilator comprises a dilating balloon, a dilating catheter and a dilating balloon pressure controller and is characterized in that the dilating balloon is connected with one end of the dilating catheter. The other end of the dilating catheter is connected with the dilating balloon pressure controller. Liquid is filled in the dilator. The dilating balloon is made by elastic rubber, volume of the balloon can be changed through the dilating balloon pressure controller, and the balloon is of an elliptical ball shape. The dilating catheter is a touch silica gel catheter with certain deformability. The dilating catheter is provided with scale marks. During operation of the dilator, the liquid can flow in the dilating catheter. The dilating balloon pressure controller of an elliptical ball shape is made of elastic rubber, and original shape and volume of the pressure controller can be restored automatically and fast when external force is removed. Accurate positioning of the narrow sections is performed before treatment, and specific treatment schemes are decided according to treatment requirements and tolerance degree of the patients.
Description
Technical field
This utility model relates to a kind of device of expanding the narrow section urethra, is particularly useful for male patient's dilating urethra treatment urethral stricture voluntarily.
Background technology
Male urethral stricture is one of Urology Surgery common disease, and due to the particularity of male urethra anatomical structure and function, the treatment of male urethral stricture or locking is one of difficult problem of facing of Urology Surgery doctor always.Easily recurrence after urethral stricture treatment (conservative expansion or operation), often need repeatedly or lifelong dilation therapy, in the course for the treatment of, often there will be multiple complications etc. perplexing all the time the clinicist.At present, known urethral stricture Therapeutic Method mainly contains: dilation of urethra, various intracavity operation, open surgery and multiple technologies therapeutic alliance.Different Therapeutic Method has indication separately, and pluses and minuses are respectively arranged, but it is available to there is no at present solely standard care mode.For long section (>=2cm) urethral stricture, therapeutic strategy mostly is operative treatment, and, for the urethral stricture of narrow section shorter (<2cm), adopts dilation of urethra, various intracavity operation and multiple technologies therapeutic alliance more.The patient with examining, optionally carries out dilation of urethra again in urethral dilatation postoperative often need regularly.Some urethral stricture patients there will be repeatability, intractable urethral stricture or narrow increasing the weight of after dilation of urethra or intracavity operation, analyze its main cause may be: after (1), expansion finish, scar tissue loses the support of expansion external force and elastical retraction; (2), when expansion struts and tears or the scar tissue healing of urethra Endopyelotomy forms cicatrix again; (3), traumatic infection, cicatrix is adhered the scar tissue that formation is larger; (4), again do not expand in time the effect of consolidating last expansion after the expansion.Up to now, also do not have the patient to use voluntarily the report of dilator dilating urethra, more be not applicable to the dilator that the patient expands the narrow section urethra voluntarily and emerge.
Summary of the invention
In order to overcome after urethral stricture treatment the narrow and narrow difficult problem increased the weight of repeatedly, and then improve patient's urinary function and complication, the application of divulsor is expected to bring practical advantages for part urethral stricture patient.The dilator that this utility model provides a class to be applicable to the urethral dilatation of male urethral stricture patient narrow section and a kind of new method that the patient uses dilator to treat voluntarily in the urethral stricture long-term treatment.
this utility model solves the technical scheme that its technical problem adopts:dilator has the characteristics of on design concept---and controlled expansion,, in the process that need to be expanded the narrow section urethra according to concrete treatment, the degrees of expansion of urethra, expansion persistent period and dilation therapy are controlled flexibly the course for the treatment of.
Divulsor is by dilating sacculus, dilating catheter, and the dilating sacculus pressure controller forms, it is characterized in that: dilating sacculus is connected with dilating catheter one end, the other end of dilating catheter is connected with the dilating sacculus pressure controller, and whole device sealing, inside fill with liquid (as normal saline); Dilating sacculus is made by gum elastic, can change its volume by the dilating sacculus pressure controller, and being ellipsoid shape and its length of maximum gauge perpendicular to the urethra major diameter during expansion is that 0.6cm(normal urine road caliber is 0.5-0.6cm); Dilating catheter is the tough silica gel pipeline of a matter, has certain deformability, indicates scale (length 20cm), its interior negotiable liquid during dilator work; The dilating sacculus pressure controller is made by elastic rubber, is the ellipsoid shape, and while removing external force, it can recover original shape and volume automatically.After, dilatation light for stenosis or the routine expansion after intracavity operation and the urethral stricture patient who is unwilling to be treated surgically, can try out this extension fixture, the patient also can use voluntarily this device at home after training.Before using the urethra prop to be treated, the patient need go the X-ray urethrography and determine the distance of narrow positions apart from urethral orifice, determines the length of dilating catheter insertion urethra according to this distance, guarantees that dilating sacculus is placed in narrow positions.During divulsor work, hold the dilating sacculus pressure controller, by adjusting the bulked volume that the pressure of dilating sacculus pressure controller is changed to dilating sacculus, the pressure that after treatment intermittence or end, only need reduce or remove the dilating sacculus pressure controller gets final product.The bulked volume of dilating sacculus, rate of expansion, expansion persistent period and interval determine by dilation therapy actual needs and patient's tolerance degree.
the beneficial effects of the utility model are: by controlled expansion narrow section urethra to reduce the urethral stricture degree, the after treatment effect, the generation that improves patient's dysuria symptom and reduce related complication from, and reduce as far as possible or avoid operative treatment.
The accompanying drawing explanation
Below in conjunction with accompanying drawing this utility model, further illustrate.
Fig. 1 is principle of compositionality figure of the present utility model.
Fig. 1 a is not duty structural map of dilator.
Fig. 1 b is dilator duty structural map.
In figure: 1. dilating sacculus, 2. dilating catheter, 3. dilating sacculus pressure controller.
The specific embodiment
In this utility model shown in Fig. 1 is implemented, determine that according to the X-ray urethrography dilating catheter (2) need to insert endo-urethral length, thereby dilating sacculus (1) accurately is placed in to the urethral stricture position; During dilation therapy, hold dilating sacculus pressure controller (3), the pressure of increase to dilating sacculus pressure controller (3), make its inner liquid be squeezed into dilating sacculus (1) by dilating catheter (2) thus make dilating sacculus (1) expansion, the sacculus of expansion produces pressure to the narrow section urethra of intending expansion, thereby expands this place's urethra; In expansion intermittence or while end, reduce or remove the pressure to dilating sacculus pressure controller (3), because dilating sacculus pressure controller (3) has the elastical retraction ability, it is the fast original shape of quick-recovery and volume voluntarily, the interior liquid of dilating sacculus (1) just flows back in dilating sacculus pressure controller (3) automatically by dilating catheter (2), whole process can be carried out repeatedly, thereby reaches therapeutic purposes.
