Abstract
The utility model discloses a urethra anesthesia intermittent dilator, which comprises a guiding head 1, an air tube 2, an injector 4, a handle 3 and an air filling sac 5, wherein a dilatation air sac ring 6 is bonded on the air tube 2 below the guiding head 1, and the dilatation air sac ring 6 is communicated with an inner cavity of the air tube 2; a liquid guiding tube 8 is arranged in the cavity of the air tube 2, and the rear end of the liquid guiding tube 8 is connected with the injector 4; the air filling sac 5 is arranged on the lower part of the handle 3; when the air filling sac 5 is inflated, the air passes through a communicating tube 10 to enter the air tube 2 to enter the dilatation air sac ring 6 through a ventilation hole 9 to enable the dilatation air sac ring 6 to bulge to dilate the wall of a urethra. The urethra anesthesia intermittent dilator has the advantages of simple structure and convenient use; unnecessary pain of patients can be relieved, and occurrence of complications can be prevented; the processes of anesthesia, intermittent dilatation and forward travelling can be carried out simultaneously, and the utility model can also be used for urethral catheterization to improve success ratio of operations.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and specifically a kind of urethra is anaesthetized intermittent dilator, uses when being applicable to Urology Surgery treatment urethral stricture.
Background technology
Urethral stricture is the common disease of Urology Surgery, and urethral dilatation then is the important means of treatment urethral stricture.Present employed divulsor is used solid metal bar, hollow metal bar or thread metal probe mostly, and the first two plants point of front end, and a kind of afterbody in back is the bolt shape head, its weak point is: because bonding jumper is thin more, its front end is also sharp more, easily punctures mucous membrane of urethra, cause hemorrhage, or form via, thread metal probe is easily twisted, is fractureed, when running into the urethral stricture position, be difficult for passing through, worked if be eager to excel, and can make the patient produce the great pain sense for a long time, and be unfavorable for performing the operation and carry out.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to operate, prevent complication, the urethra that can alleviate the unnecessary misery of patient anaesthetizes intermittent dilator.
For reaching above purpose, the technical scheme that this utility model adopted is: this urethra is anaesthetized intermittent dilator, comprise target seeker, trachea, syringe, handle, gas cell constitutes, the front end of trachea is fixedlyed connected with target seeker, fixedly connected with handle in the rear end of trachea, expanded balloon ring on it is characterized in that boning on the trachea outer wall below target seeker, the inner chamber of expanded balloon ring is by the intracavity inter-connection of passage on the tracheal wall and trachea, the target seeker front end is provided with liquid outlet, intracavity at trachea is provided with catheter, the front end of catheter communicates with liquid outlet, and the rear end of catheter is connected with syringe, and anesthetis is housed in syringe, anesthetis in the syringe sprays in liquid outlet by catheter, the urethra inwall is anaesthetized, establish gas cell in the bottom of handle, gas cell was connected with trachea by the communicating pipe in the handle, when gas cell is inflated, gas enters the expanded balloon ring by passage again through communicating pipe entering trachea, makes the expanded balloon ring heave the dilating urethra wall.This utility model is also implemented by following measure: described target seeker profile is the semicircle shape head, so that can not stab urethral wall; The shape of described trachea and human body urethra shape adapt, so that can enter smoothly; Described expanded balloon ring is made by medical elastic silica gel, in use, fill with anesthetis in the syringe, when the unaerated of expanded balloon ring, target seeker is stretched into along urethra, the spray anesthetis while stretching into, after arriving the urethral stricture place, with the gas cell inflation, the expanded balloon ring is heaved, the dilating urethra wall, target seeker slowly enters the stenosis area venting forward, and target seeker slowly advances forward again, and spray anesthetis, inflation again, the expanded balloon ring is expanded once more, and so circulation is finished until operation, after having sprayed anesthetis, available liquid outlet and catheter carry out urethral catheterization simultaneously.
The beneficial effects of the utility model are: simple in structure, easy to use, can alleviate the unnecessary misery of patient, prevent complication, and anesthesia, intermittently expansion and advance forward and can carry out simultaneously, but also urethral catheterization has improved the success rate of operation.
