Background
Acute urinary retention is one of the common diseases in emergency treatment of urinary surgery, the main causes include benign prostatic hyperplasia, bladder neck contracture, urethral stricture, bladder outlet obstruction caused by urethral trauma and the like or the destruction of urethral integrity, and the urinary catheter is usually required to be retained in emergency treatment. However, some of the patients in clinic have difficulty in catheterization, and a urinary catheter needs to be inserted after urethral dilatation, so that the patients are subjected to pain caused by multiple catheterization operations, and are easy to have serious hematuria, infection and other risks. Moreover, even after urethral dilation has been performed, there are still many patients who have failed to successfully place catheters either because the urethral dilator has not entered the bladder, or because the catheter, even after removal of the urethral dilator after entering the bladder, has not been placed because the flexibility of the catheter is significantly lower than that of the urethral dilator or for other reasons. For patients who can not be placed with the catheter, the operation with larger trauma such as cystoscope catheterizing placement or suprapubic cystostomy is needed. Significantly increasing the pain of the patient and the related risks of hematuria, infection and the like.

In order to realize the technical purpose, the utility model discloses the technical scheme who takes does:
a novel urethral dilator capable of being placed into an indwelling catheter, wherein: including leading the core, it includes handle portion, straight tube portion and elbow portion to lead the core, straight tube portion front end and elbow portion smooth connection, straight tube portion rear end is connected with handle portion, the one end that straight tube portion was kept away from to the elbow portion is round moist head structure, handle portion, straight tube portion and elbow portion integrated into one piece, straight tube portion lateral wall cover is equipped with the epitheca, the epitheca is used for expanding the urethra and keeps somewhere in the urethra, the insertion of the catheter of being convenient for.
In order to optimize the technical scheme, the specific measures adopted further comprise:
further, the straight pipe part is of a cylindrical structure, and the circumference of the straight pipe part is uniform from the front end to the rear end.
Furthermore, the sheath head part 6 of the sheath 5 is attached to the joint of the straight pipe part 3 and the elbow part 4, and the sheath tail part 7 of the sheath 5 is flush with the straight pipe part 3.
Furthermore, the tail part of the sheath is provided with a reverse-folding fork for tearing and pulling out the sheath.
Furthermore, the thickness of the tube wall of the sheath is 0.2-0.5mm, and the sheath is made of elastic materials.
Further, the outer sheath side wall is coated with a lubricating layer.
The utility model has the advantages that:
the utility model relates to a can put into novel urethra expander of keeping somewhere catheter, can once only accomplish the urethra expansion and keep somewhere the operation of catheter, the coating has the lubricant film on the epitheca simultaneously, reduce the damage to the urethra mucosa, can avoid the patient to experience the operation of catheterization many times on the one hand, on the other hand still can avoid still facing the problem of keeping somewhere the catheter failure after the urethra expansion, and then need go under the cystoscope catheter and put into the operation that the wound is bigger such as art or suprapubic cystostomy, can show the pain and the hemorrhage that reduce the patient, risks such as infection.
