The utility model has the advantages of accurately anesthetizing the surface of male urethra mucosa, obviously reducing pain scores of patients during cystoscopy, shortening operation time and avoiding the occurrence of related complications such as bladder perforation and long-term stenosis caused by urethral injury due to the fact that the patients cannot tolerate the operation.
Description
Technical Field
The utility model belongs to a urinary surgical instrument, which is suitable for urethral mucosa surface anesthesia before male patient cystoscopy, urethral dilatation, urethral, bladder and upper urinary tract retrograde radiography examination.
Background
Cystoscopy is the most basic and commonly used interventional examination technique for urological diseases, such as the initial diagnosis of hematuria, and the gold standard examination for the postoperative review of urological diseases, especially urothelial cancer, glandular cystitis, etc.
However, in the case of male patients with high incidence of bladder cancer, due to the unique anatomical features of the urethra, not only the urethra is longer, but also three physiological curves exist, and most of patients have poor effect in cystoscopy due to the fact that the surface anesthetic is injected by the currently adopted simple syringe (especially, a primary operator fails to inject the anesthetic or directly injects the drug into the bladder, and the urethral mucosa is less remained), so that the male patients are called to be "tiger-like". Although patient tolerance is significantly improved due to the current introduction of cystoscope, the problem of urethral mucosa anesthesia is still not solved. In addition, urethral dilation in urology, cystourethography, and retrourethrography are also invasive procedures, and adequate and effective anesthesia of the urethral mucosa is essential.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and solve the problem of poor anesthesia effect on the surface of the urethral mucosa of a male.
In order to achieve the purpose of the utility model, the utility model provides a male urethra mucosa surface anesthesia device, which comprises a catheter, wherein the tail end of the catheter is closed, and the head end of the catheter is provided with an anesthetic liquid leading-in hole; the utility model discloses a catheter, including pipe, glans penis, catheter outer loop, the umbrella ring piece that is used for laminating the glans penis is established to the catheter outer loop, the tail end bending of umbrella ring piece outward flange orientation pipe, the catheter is laid anesthesia liquid delivery hole on the lateral wall between umbrella ring piece to the tail end.
The size of the umbrella-shaped ring piece is completely attached to the surface of the top end of the glans penis, the width of the umbrella-shaped ring piece is not too large or too small during manufacturing, and the prepuce or the glans penis is prevented from being scratched by the edge. The flow direction of the anesthetic liquid in the catheter flows through the inner cavity of the catheter from the anesthetic liquid leading-in hole, and is finally sprayed and guided out from the anesthetic liquid leading-out hole to the surface of urethral mucosa.
Preferably, the umbrella-shaped ring sheet is made of a soft silica gel film.
The concave surface of the soft silica gel film is relatively smooth, and does not stimulate sensitive glans penis.
Preferably, at least two anesthetic liquid outlet holes are an array group, and the anesthetic liquid outlet holes in the array group are arranged in a long strip shape along the axial direction of the catheter.
The array group referred to here is a set of a plurality of anesthetic liquid outlet holes, the central connecting line of which is parallel to the central axis of the catheter, and can be arranged on the whole section of the urethra to realize accurate and sufficient anesthesia to the urethral mucosa.
Preferably, the array groups are at least two groups, and the guide pipes are uniformly distributed in the array groups along the circumferential direction; the anesthetic liquid outlet holes in the adjacent array groups are staggered relatively in the axial position.
The anesthesia liquid leading-out holes in the adjacent array groups are staggered relatively in the axial position, and the anesthesia liquid leading-out holes are not arranged on the same peripheral position of the catheter in two adjacent array groups at the same time, so that all the anesthesia liquid leading-out holes form a spiral downward shape around the catheter body on the whole.
Preferably, five anesthetic liquid outlet holes close to the position of the catheter head in each array group are arranged at one centimeter intervals; the arrangement interval of the rest anesthetic liquid leading-out holes in the array group is two centimeters.
Preferably, the anesthetic liquid outlet holes close to the position of the catheter head are densely arranged, and the anesthetic liquid outlet holes far away from the position of the catheter head are sparsely arranged.
Preferably, the length of the conduit is 15cm, and the outer diameter is 12 mm; the anesthetic liquid leading-in hole is communicated to a 20ml injector liquid discharging hole; the umbrella-shaped ring piece is fixed near the head end of the catheter.
The male urethra starts from the internal orifice of the urethra and ends at the external orifice of the urethra at the tip of the glans penis, the adult grows about 17-20cm, and the male urethra can be divided into 3 parts from inside to outside: the prostate part is about 3-4cm long, the membrane part is about 1.5cm long, and the cavernous part is about 12-17cm long, and the prostate part and the membrane part become the posterior urethra and the cavernous part is called the anterior urethra clinically.
The device mainly relates to surface anesthesia of anterior urethra mucosa, so that the total length of the catheter is designed to be 15cm, the diameter of the catheter is 12mm, and reasonable pressure for leading out can be generated by means of anesthetic liquid injected by a 20ml syringe on the premise of covering the mucosa.
The anesthetic liquid eduction hole of the side wall is matched with the tail end to be sealed, so that anesthetic liquid is prevented from being directly injected into the bladder, the anesthetic liquid is sprayed to urethral mucosa from the anesthetic liquid eduction hole on the tube side, the contact area of the medicament and the mucosa is increased, and the anesthetic effect is enhanced.
The application of the umbrella-shaped ring piece soft silica gel film ensures that after the umbrella-shaped ring piece is contacted with the wet glans penis, the smooth surface of the glans penis can be adsorbed and wrapped by the negative pressure generated after the attachment, and the gap between the device and the glans penis is closed, so that the anesthetic liquid is prevented from being exposed in a backflow mode after entering the urethra.
Through the design that the anesthetic liquid outlet holes in the adjacent array groups are staggered relatively in the axial position, the power of anesthetic liquid in the catheter is more reasonable, and the flow control of each anesthetic liquid outlet hole is convenient to realize.
The anesthetic liquid leading-out holes in the array group are dense, rare and orderly, so that the medicine can be continuously sprayed to the surface of the urethra under pressure, the anesthetic liquid leading-out holes at the head end are relatively dense, the enough medicine amount is ensured, and the redundant medicine amount can flow into the posterior urethra along the urethral mucosa by means of the liquid gravity. Thereby realizing the maximum contact time of the anesthetic liquid and urethral mucosa and ensuring the sufficient anesthetic effect.
The design of the suitable size of device relies on syringe pressure when connecting the suitable syringe that is equipped with anesthetic liquid, will make anesthetic liquid spray to the urethra mucosa from pipe side anesthetic liquid delivery orifice, and the area of contact of maximize medicament and mucosa reduces invalid clearance, improves anesthesia effect.
The male urethra mucosa surface anesthesia method has the advantages that male urethra mucosa surface anesthesia can be performed in a targeted mode, pain scores of patients can be obviously reduced when the male urethra mucosa surface anesthesia method is applied, operation time is shortened, and related complications such as bladder perforation and long-term stenosis caused by urethra injury are avoided.
