Hollow one-piece urethral dilator

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a hollow one-piece urethral dilator.

Background

Urethral stricture in men caused by trauma, inflammation and other factors is a common but intractable class of diseases in urinary surgery, and urethral dilatation is one of the main ways to treat urethral stricture. The classic and most widely used urethral dilation is the gradual dilation of a stenotic urethra by means of a metal urethral dilator to ensure unobstructed urination.

In clinical work, patients who need urethral catheterization due to urine retention are more frequent, some male patients often have urethral catheterization failure due to urethral stricture and distortion, and in this time, a urethral catheter needs to be left after urethral dilatation, but sometimes a metal urethral dilator can be smoothly dilated into a bladder, the urethral catheter still cannot be smoothly inserted into the bladder after a probe is removed, and at the moment, suprapubic bladder puncture fistulization needs to be performed or a guide wire needs to be inserted into the bladder under direct vision of a cystoscope in an operating room, and then the urethral catheter is inserted under the guide of the guide wire.

The bladder fistulization has relatively large trauma and risk, and if the patient is in poor general condition or is not suitable to move due to combined fracture, the patient is also not suitable to go to an operation room for cystoscope. Therefore, the metal urethral dilator with the middle channel and capable of smoothly placing the guide wire is designed, and has certain clinical application value; the existing urethral dilator is generally F14-F26 in model number (from thin to thick), but the purpose of dilation cannot be achieved by using the thinner urethral dilator, and the use of the thicker urethral dilator can cause huge physiological pain to a patient, and if the urethral dilator is not used properly, the patient can be injured.
