Description

A kind of divulsor

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of divulsor.

Background technology

Along with the Urology Surgery development; urodynamic study; as one of Urology Surgery routine examination; be expert at and insert urine power conduit when urine power is checked; usually can because of urine power conduit more carefully, weak, add that patient's prostatic hyperplasia is bigger; cause and urine power conduit can't be inserted corresponding position; cause and check failure; and can be because check failure; the doctor can't understand the bladder function situation; increase the uncertainty of further therapeutic scheme, improved surgical risk and increased the weight of patient and family members' psychological burden simultaneously.It is a kind of conventional means that urethral stricture is treated that divulsor carries out urethral dilatation, by the expansion of dilator, makes the narrow expansion.

Existing divulsor is mainly metal divulsor and thread dilator, is solid metallic rod, and both in use, the insertion of plastics silk is all comparatively difficult, be difficult for the narrow urethra of lucky insertion, and the guide wire bar is not firm by back as connection, may come off and fall into bladder.

At above-mentioned situation, occurred a kind of on the existing market easily by urethral stricture portion, can not stab the divulsor of urethra again,, have the body of a silk guide passage in the divulsor as the disclosed a kind of divulsor of China Patent No. " 200820100821.1 ".The plastics silk can insert in the narrow urethra by silk guide passage, but silk guide passage is arranged on divulsor inside, be difficult for observing the insertion situation of plastics silk, be difficult for making divulsor to withdraw from from plastics silk rear portion, also has conventional urine power inspection before urinary system prostate patient's art, urine power conduit is not only thin but also hard, normal conditions can't be implanted urethra with urine power conduit, can guide urine power conduit to implant though use above-mentioned divulsor, but it is intravital that the silk guide passage of above-mentioned divulsor is arranged on pipe, divulsor can't withdraw from from urine power conduit rear, causes and checks failure.

Should in time urinate fast at the acute urinary retention patient, it is that prostatic hyperplasia is seriously oppressed urethra mostly that acute urine pool reason takes place, cause and to urinate, the doctor needs timely urethral catheterization, just can alleviate the patient suffering, and existing catheter is softer mostly, usually be difficult to put into fast, often need divulsor that the urethral compression position is expanded, and traditional divulsor can only be expanded.

Summary of the invention

The purpose of this utility model is at existing deficiency, and providing a kind of can insert by guiding urine power conduit, and the divulsor extracted easily of divulsor.

The purpose of this utility model can realize by following technical proposal: a kind of divulsor comprises the circular body of a strip it is characterized in that described body lateral wall is provided with a guiding groove along body axis direction and conducting body two ends.

This divulsor is provided with a guiding groove on the body lateral wall, this guiding groove can guide the insertion of plastics silk, and can observe the situation that the plastics silk inserts, because above-mentioned guiding groove is the outside that is positioned at the divulsor body, when the plastics silk is inserted into corresponding position, divulsor is extracted easily, and this divulsor is made of metal material.

In above-mentioned divulsor, an end bending of described body, above-mentioned guiding groove is through the curved interior face.The purpose of She Zhiing is the insertion operation of convenient guiding plastics silk like this, the insertion situation of observing the plastics silk easily.

In above-mentioned divulsor, between described guiding groove and the body smooth arc surface.At divulsor during, be difficult for urethral wall caused situations such as scuffing to the expansion of urethra.

In above-mentioned divulsor, described guiding groove is circular, V-arrangement or square.During fabrication, the guiding groove on the divulsor can be done circular, V-arrangement or quadrate by the mode of extruding, preferably is used as forming V-shape.

In above-mentioned divulsor, the end of the crooked end of described body is slick reducing, and the end face of this reducing is slick sphere.When divulsor uses, insert in advance in the urethra by the crooked end of body, the purpose of She Zhiing makes divulsor insert urethra easily like this, and end face is that slick sphere insertion urethra can not cause situations such as scuffing to urethra.

In above-mentioned divulsor, described sphere and body seal and are integral structure.The purpose of She Zhiing is the smooth end that makes the crooked end of body like this, makes things convenient for the end to insert in the urethra.

In above-mentioned divulsor, the other end of described body is flat.In use, this flat is held for taking of medical personnel, makes things convenient for operation of medical workers.

In above-mentioned divulsor, the angle between crooked end of described body and the body is greater than 90 degree.The purpose of She Zhiing is like this, when the crooked end of body inserts urethra, guides the body of divulsor to insert easily, and is easy to use.

In above-mentioned divulsor, an end knee of described body is circular-arc.Make divulsor insert urethra easily, situations such as scuffing when inserting urethra, can not occur urethra caused.

Compared with prior art, this divulsor is provided with a guiding groove along body axis direction and conducting body two ends on the body lateral wall, urinary system prostate patient is expert at, and urine is moving to be learned when checking, can insert novel divulsor earlier, the moving conduit of urine can be put into bladder along guiding groove then, does flow process having simplified behaviour like this, when alleviating the patient suffering, also improve the success rate of putting pipe greatly, reduced operation risk; After urine power conduit inserts, because above-mentioned guiding groove is positioned on the body lateral wall, can extract divulsor easily, simple in structure, easy to use, also have this divulsor also can be used in the middle of the acute urinary retention patient, can pass through the quick urethral catheterization of guiding groove, alleviated bladder and damaged when increasing the weight of and striven for the time for next step treatment; After urethral catheterization finishes, also can put into zebra seal wire or ureteral catheter, keep seal wire then and withdraw from dilator along guiding groove, under the seal wire guiding, insert catheter again, reduce the urethral catheterization difficulty, saved treatment time, alleviated the misery that the patient produces because of quick urethral catheterization.
