Description

Support catheter special for male posterior ureter injury

The utility model relates to a kind of catheter, is male posterior urethra damage special stand conduit specifically.

At present, the support tube of each medical institutions use when the damage of treatment male posterior urethra is the non-Li Shi catheter (foleyShi pipe) of two cavity single-bags basically entirely.Be difficult to obtain the curative effect of duration healing.The catheter that uses is thick a bit, also can oppress normal mucous membrane of urethra skin, causes new damage.The two capsule urinary catheters of two-chamber of comrade's developments such as Suihua City first hospital Du Yongnian can only use in operation, and intraluminal pressure is passive adjustment, use inconvenience.

The emergency case phase of male posterior urethra damage handles, and has difference for many years always.Emergency treatment urethra kposthesis treatment can obtain the first phase curative effect, but wound is big, and the critical sick and wounded are difficult to stand, and is prone to sexual impotence, urethral fistula etc. and issues licence.And the Therapeutic Method simple, that wound is little can cause urethral stricture again, even atresia of urethra.Also need operation once more, the treatment of row urethra kposthesis; Do not need operative treatment person once more, need the regular urethra expansion treatment of long period yet.

The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of three-cavity and double-caspula conduit.It is male posterior urethra damage special stand conduit.

This utility model technical solution:

A kind of male posterior urethra damage special stand conduit, the scaffold tube afterbody has the tube chamber that communicates with the support capsule, the tube chamber that communicates with fixing capsule.Urine drainage lumen, the scaffold tube head has conduction hole, and the conduction hole rear portion is fixing capsule, it is characterized in that the scaffold tube top has small sircle hole, fixedly has the support capsule behind the capsule, and support capsule length is 5-6 centimetre.

Advantage of the present utility model:

Male posterior urethra damage special stand conduit can become urine and join forces the success of art intubate through the less urethral catheterization of wound.Under the X line, can change during the treatment by observing support scrotiform attitude.Speculative arbitration injury of urethra degree, the time of support tube is kept somewhere in decision thus.As required, can adjust the support intraluminal pressure at any time.Accomplish to prevent urethral stricture, can avoid the sphincter damage again, to reach ideal therapeutic effect.The conduit that uses is thin slightly, avoids causing new damage because of oppressing normal urethra mucous epithelium.Like this, male posterior urethra damage.In the curative effect that the emergency case phase just can be obtained duration Zhi More through the less urethral catheterization of the patient wound of the sick and wounded or urethral reunion operation, also can avoid appearance because of complication such as sexual impotence that row urethra kposthesis is caused, urethral fistulas; The elderly men patient also can play the effect for the treatment of hyperplasia of prostate simultaneously.

Fig. 1 is this utility model structural representation.

Below in conjunction with accompanying drawing this utility model is further described:

Scaffold tube length of the present utility model and diameter are identical with the foleyShi catheter of same size, conduit with histocompatibility preferably silicone rubber make.Cyst wall is made with toughness, the strong material of epistasis.Break in case use midway.Because of posterior urethral injury mostly is blue or green shape year, production specification is that Fr12,14,16, No. 18 can satisfy clinical use for 4 kinds substantially.

Among the figure: 1 is the tube chamber opening that communicates with the support capsule.3 tube chamber openings for communicating with fixing capsule.All be used in capsule, injecting or emitting liquid, 2 is the urine drainage lumen opening of scaffold tube, the bladder urine is outside this chamber lead body, Fr8 metal bougie can be inserted to the scaffold tube top in this chamber, but bougie can not pass top small sircle hole 8, in case when using the metal bougie to help the urethral catheterization intubate, cause injury of urethra to increase the weight of and occur via.Scaffold tube tail end bifurcated is three single lumen catheters different in size.Be to be convenient to operation in order to use to distinguish the people.4,5 be respectively and feed the support capsule 10 and the fixing tube chamber of capsule 9,6,7 for feeding the tube chamber openings of two capsules.Distance is 05 centimetre between two capsules, the length of support capsule 10 is 5-6 centimetre, support capsule 10 is cylindric when filling, diameter can reach (diameter that is a bit larger tham urethra) more than 2 centimetres, the moulding effect that allows it play the regeneration of damage urethral tissue, to repair, prevent urethral stricture, 8 is scaffold tube top small sircle hole, 02 centimetre of diameter, can pass through by the Fr4 ureteral catheter, utilization is inserted drainage tube chamber through this hole with the seal wire other end after urethroscope is spied on down with seal wire one end insertion bladder, guide through seal wire.Bladder can be inserted in the scaffold tube top.Urethral catheterization is succeedd.11 be drainage tube chamber at intravesical opening, urine is got rid of external after this opening flows into tube chamber.Fixedly injecting liquid in the capsule 9 gets final product for 10～15 milliliters, it is positioned at intravesical, play the effect that the fixed support conduit prevents slippage, can inject radiography in the support capsule 10, get final product about adult's consumption 12ml, the concrete amount of liquid that injects should decide as required, and maximal dose does not break with cyst wall, and injury of urethra does not increase the weight of to be standard.
