Abstract
The utility model relates to a casing-tube type urethra dilator, belonging to the medical device. Pointing at the defects that the device used in the existing operation of the urethra dilation brings the patient the pain and causes the subsidiary injury of the urethra because of inserting the tube repeatedly, the utility model develops a novel casing-tube type urethra dilator. The utility model is composed of an inductive probe, two elliptical shuttle-shaped dilating probe heads and a casing tube with scales. The dilator which is inserted in the urethra once can be used for reducing the chances of the contamination and the infection, shortening the operation time, and relieving the pain of the patient. The device has easy manufacture, convenient operation and low cost.
Description
This utility model belongs to medical instruments field.
The method of the back of prophylactic treatment operation at present urethra cicatricial stricture is a dilation of urethra at once after extracting urethra tube after the operation.The apparatus that uses is the metal divulsor, and model is that 8-26 probe expands according to the certain hour order.1-3 week expands 1-2 time weekly after the tube pulling, and per two weeks in 3-11 week expand once, and expand once every month after 11 weeks, after patient's operation, nearly 1 year domestic demand row urethral dilatation 17-20 time.The each expansion needs to plug in dilator 6-10 time repeatedly, causes big misery to patient, and intubate causes the secondary damage of urethra repeatedly, occurs the tissue at the normal position of urethra simultaneously because dilatation is subjected to repetitious stimulation and damage.
The purpose of this utility model is to have developed a kind of novel bushing type divulsor at the deficiency of existing divulsor and shortcoming.
The purpose of this utility model has taked following technical scheme to realize, this bushing type divulsor is induced the probe by one and is made up of oval fusiform dilatation probe of two different sizes and the sleeve pipe that is carved with yardstick, and the oval fusiform dilatation of two different sizes is popped one's head in and is fixedly mounted on the sleeve pipe.Oval fusiform dilatation probe can be made the different series expansion probe of some specifications according to different patients.
Use this bushing type divulsor that following advantage is arranged:
1, utilize " dynamic expanding " principle, expansion effect is good.
2, oval fusiform dilatation probe is more suitable for urethra physiological characteristics and pathological anatomy.
3, the probe only inserts urethra once, and stimulation when reducing repeatedly intubate and side effect reduce opportunities for contamination.
4, just decrease the position expansion, reduce stimulation and secondary damage normal urethral tissue in disease.
5, treatment time is operated in shortening.
6, simple, the easily manufacturing, easy to operate, safe and reliable, economical and practical of apparatus.
Figure of description is the structural representation of the embodiment of technical solutions of the utility model, and wherein Fig. 1 is the structural representation of inducing the probe.Fig. 2 is that the oval fusiform dilatation probe of two different sizes is fixedly mounted on cross section view on the sleeve pipe.Below in conjunction with the embodiment accompanying drawing structure of the present utility model and clinical using method are further described:
This bushing type divulsor is made up of an elliptic cone fusiform dilatation probe (3) of inducing probe (1) and two different sizes and the probe sleeve (2) that is carved with yardstick, makes the serial oval fusiform dilatation of a plurality of specifications according to different patients' needs and pops one's head in.
At first will induce probe (1) during clinical practice, inserting urethra selects for use suitable oval fusiform dilatation probe to be fixedly mounted on to form on the sleeve pipe bushing type expansion probe to be inserted in from the back of inducing the probe to induce on the probe, inserting urethra along it slowly helps when increasing to resistance and can learn on the yardstick of scribing from sleeve pipe that the disease that reaches predetermined decreases the position degree of depth, slowly visit again, visit the drilling depth degree and can stop surely according to resistance size and doctors experience after number picks up minute, respectively turn 90 degrees 2-3 time along counter clockwise direction and slowly withdraw from again.Repeat aforesaid operations but more preceding once visit a dimensioning, repeatable operation 4-6 time more.Decrease the position explanation by disease smoothly until probe and reach predetermined expansion effect.
The probe of the especially little replaceable bigger specification of resistance when if the position is decreased by disease in the probe of selecting for use expansion back.Again expand once by aforesaid operations, can reach encouraging result.
From the existing in theory treatment clinical course of treatment is when each insertion divulsor is organized by the disease damage, to disease decrease tissue finish once expansion acquire a certain degree constant, keep certain hour (dilator stays the time of putting) transfer to the back sick decrease to organize finish once loose being referred to as " static expansion " again.
And the operation principle of divulsor provided by the utility model is " dynamic expanding " principle.
The probe of bushing type divulsor is the elliptic cone fusiformis, its cross section is oval, on oval major axis, organize suffered expansionary force to be greater than the expansionary force that the minor axis place is subjected in the time of in inserting the ring-type sphincter of urethra, when oval fusiformis is rotated, the position of major and minor axis constantly changes, the power that ring-type sphincter any point place is subjected to also constantly changes thereupon, impels the sick damage of ring-type sphincter to be organized under certain expansion state constantly to expand-loose.Along with the probeing into and withdraw from of probe, the sick damage organized also expansion thereupon-lax and along with probe probes into the increase of yardstick, the sick lax amplitude of tissue expander of decreasing also increases.In a word in whole therapeutic process, sick decrease organize be in all the time dynamic expansion-relaxed state promptly " dynamic expanding " thus played better clinical effectiveness.
Claims (3)
1, a kind of bushing type divulsor is characterized in that: induce probe (1) and have the oval fusiform dilatation probe (3) and the sleeve pipe (2) of two different sizes to be formed by one, the oval fusiform dilatation of two different sizes is popped one's head in and is fixedly mounted on the sleeve pipe.
2, bushing type divulsor as claimed in claim 1 is characterized in that being carved with yardstick on the sleeve pipe (2).
