Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an ultrasonic visualization development catheter. Background Art

[0002] In the clinical practice of urology, patients need to be catheterized. The male urethra is long and has the following characteristics: "two bends and three narrows". The two bends refer to the anterior pubic bend and the subpubic bend, and the three narrows refer to the narrowing of the external urethral orifice, the narrowing of the internal urethral orifice, and the narrowing of the membranous urethra. The prostate is an important gonadal organ in the male reproductive system. It looks like a millet and is located behind the pubic symphysis. The part it surrounds is the external urethral sphincter; the back is connected to the bladder neck and may bulge into the bladder; the ventral side is attached to the back of the pubic bone, and blood vessels such as the dorsal vein of the penis pass through the gap; the normal prostate has a transverse diameter of about 4cm, a vertical diameter of about 3cm, and an anteroposterior diameter of about 2cm. The volume of the prostate increases with age. The incidence of benign prostatic hyperplasia in men over 70 years old is as high as 40%. Benign prostatic hyperplasia leads to urethral outlet obstruction, and acute urinary retention is one of the most important and common complications of benign prostatic hyperplasia. Catheterization is usually required. Elderly male patients with benign prostatic hyperplasia will face varying degrees of difficulty in intubation. The operation of indwelling urinary catheter must be gentle to avoid repeated operation that may damage the urethral mucosa and cause mucosal edema. Some patients also have difficulty in intubation and repeated operation that leads to heavy bleeding, so they switch to bladder puncture or cystostomy to drain urine, which is also prone to forming false passages, causing pain and risks to patients.

[0003] In the prior art, silicone balloon catheter hoses are commonly used for urinary catheters. There are many models ranging from thin to thick. The commonly used models for adults are 12F, 14F, 16F, and 18F. The outer diameters are 4 mm, 4.7 mm, 5.3 mm, and 6 mm, respectively. The commonly used clinical urinary catheter hoses can only be operated according to the curvature and stenosis of physiological anatomy. When encountering elderly male patients with prostatic hyperplasia, it is difficult to insert the catheter blindly. Therefore, it is necessary to improve the existing urinary catheters, add ultrasound-developable metal guide wires to the urinary catheter hoses, and the position of the urinary catheter hose and the position of the urethral stenosis can be observed under ultrasound guidance during intubation and catheterization. However, some patients often have abnormal urethral curvature and stenosis. The operator needs to appropriately adjust the angle and hardness of the catheter according to the position of the stenosis in order to insert the catheter smoothly, in order to avoid repeated intubation to cause damage to the urethra and prostate and the risk of intubation failure.
