Abstract

The utility model discloses a prostate dilator, the structure of which is that the tail of a main tube 3 is provided with a dilator pipe branch 2 and a fixing pipe branch 8, the outer disk below the inserted head of the main tube 3 is fixed and covered with a fixing ballonet 7 and an expanding ballonet 6, the two ends of the expanding ballonet 6 are fixed with wire rings 4 and the middle is jacketed with a movable wire ring 5, the tail of the fixing pipe branch 8 is provided with an auto sealed port 14, the fixing pipe branch 8 and the expanding pipe branch are provided inside with an inlet channel 13 and an inlet channel d12 passing the main tube 3, the tail of the expanding pipe branch 2 is provided with an inlet pressure port 1. When the utility model in use, the dilator is inserted in from the urethra of a patient, and a certain quantity of air is charged in the fixing ballonet to fix the dilator in the bladder, then air is slowly charged in the expanding ballonet to a certain pressure and the expanding ballonet is deflated after an hour to finish treatment. The dilator has a big expansionary force, good effect, simple and novel construction, low cost, and the utility model can be easily operated, patients recover quickly, and thereby the utility model is suitable for patients of hyperplasia of prostate or patients of contracture of bladder neck at different stages.

Description

The prostate dilator

One, technical field

The utility model relates to a kind of medical apparatus and instruments that is used for Urology Surgery, specifically a kind of prostate dilator that is used for treating hyperplasia of prostate.

Two, background technology

Hyperplasia of prostate is one of modal disease of elderly men, and most patient's heart lung and brain diseases can not tolerate open surgery, and it is undesirable again to depend merely on medication effect.Current, domestic many large hospitals adopt transurethral resection of the prostate in succession, because the surgical technic difficulty is big, water intoxication, severe complications such as urinary incontinence easily take place in the operation back.

Three, summary of the invention

In order to solve weak point of the prior art, the purpose of this utility model provides that a kind of price is low, expansionary force is big, eutherapeutic prostate dilator.

Realize that the technical scheme that the purpose of this utility model adopts is: this dilator mainly is made up of arm, the person in charge, expanded balloon, fixation balloon, silk ring; The tail end of being responsible for has expansion arm and fixing arm, the head end of being responsible for leaves insert head, on person in charge's periphery under the insert head successively sealing and fixing be with fixation balloon and expanded balloon, the outer two ends of expanded balloon are fixed with wire rings, the middle part is with moving metal silk ring; Fixedly the tail end of arm is provided with the automatic seal of air inlet, and the air intake duct through straight-through fixation balloon in being responsible for is fixedly arranged in the arm; The tail end of expansion arm has the air inlet pressure tap of joining by threeway and air inlet pressure tester, and the air intake duct through straight-through expanded balloon in being responsible for is arranged in the expansion arm.During application, determine patient's prostate length earlier with the B ultrasonic instrument, regulating moving metal silk ring makes the length of expanded balloon less than 3 millimeters of prostate length, the urethra of dilator from the patient inserted, fixation balloon and expanded balloon are laid respectively in the middle of intravesical and the prostate, after fixation balloon charges into certain gas, traction outward gently, determine that air bag pressed close to internal urethral orifice, reuse air inlet pressure tester stops annotating behind certain pressure by the slow gas injection in expanded balloon of air inlet pressure tap, after 1 hour the gas in two air bags is discharged fully, extract dilator, finish prostate seance the patient.

The beneficial effects of the utility model are: because the inflated prostate in a location of two air bags of this dilator, expansion pressure is feelings and decide due to illness, so this dilator expansion is accurate, expansionary force is big, good effect.This dilator novelty simple in structure, volume is little, and is in light weight, and price is low, and is simple to operate, and patient's misery is little, recovers fast, adapts to the hyperplasia of prostate patient and the bladder neck contracture patient of different times.

Five, the specific embodiment

In each figure, this utility model prostate dilator mainly is made up of arm, the person in charge, expanded balloon, fixation balloon, silk ring; Be responsible for 3 tail end expansion arm 2 and fixing arm 8 are arranged, the person in charge 3 head end leaves insert head, on the person in charge's 3 peripheries under the insert head successively sealing and fixing be with fixation balloon 7 and expanded balloon 6, the outer two ends of expanded balloon 6 are fixed with wire rings 4, the middle part is with moving metal silk ring 5; Can determine the length of expanded balloon by rolling moving metal silk ring 5; Fixedly the tail end of arm 8 is provided with the automatic seal 14 of air inlet, and automatically seal 14 is formed with fissured barrier film 10 and film interface 11 outward in the middle of in the elastic rubber belt 9 of the fixing tail end cylindrical parcel of arm 8, the arm; During resting state, the elastic force of elastic rubber belt 9 makes the crack closure of barrier film 10, when syringe nipple heads into the open injecting gas in barrier film crack, by air intake duct 13 fixation balloon 7 is filled greatly.Fixedly have in the arm 8 through being responsible for the air intake duct 13 of straight-through fixation balloon 7 in 3; The tail end of expansion arm 2 has the air inlet pressure tap 1 of joining by threeway and air inlet pressure tester (not drawing among the figure), has through being responsible for the air intake duct 12 of straight-through expanded balloon 6 in 3 in the expansion arm 2.
