Urodynamics piezometric tube for urinary surgery

Abstract

The urodynamic pressure measuring tube comprises a tube body, a pressure measuring water bag and a limiting air bag, the pressure measuring water bag and the limiting air bag are fixedly arranged on the tube body, the limiting air bag is arranged on the tube wall close to the front end of the tube body, and an inflation channel, a water bag water inlet channel and a bladder pressure measuring channel are arranged in the tube wall of the tube body. A bladder water injection opening is formed in the rear end of the tube body, a bladder pressure measuring tube, a water bag water injection tube and an inflation tube are further fixedly connected to the side wall of the rear end of the tube body, and the bladder pressure measuring tube, the water bag water injection tube and the inflation tube are connected with a bladder pressure measuring channel, a water bag water inlet channel and an inflation channel respectively. The pressure measuring tube can measure the pressure in the bladder and the pressure of sphincter at the same time, sphincter tension can be rapidly measured and evaluated before a prostate operation, and therefore an optimized operation treatment scheme is formulated, the probability of urinary incontinence of a patient after an operation is reduced, the life quality of the patient after the operation is improved, and the psychological burden of a surgeon is relieved.

Description

technical field [0001] The invention relates to the technical field of urological examination instruments, in particular to a urodynamic pressure measuring tube for urological surgery. Background technique [0002] Urodynamic examination is a commonly used examination in urology, mainly to detect the pressure, flow rate and bioelectric activity of various parts of the urinary tract, and to understand whether there is a disease of voiding dysfunction. During the inspection, a cystometry tube needs to be inserted into the bladder from the urethra for inspection. At the same time, the urethral sphincter can control the closure of the urethra to prevent urine leakage. Sometimes the sphincter pressure needs to be measured. The current cystometry tube cannot be the same. Pressure measurements of the bladder and sphincter over time. Minimally invasive surgical treatment of benign prostatic hyperplasia, different patients and surgical methods, there are still patients with differen...

AI Technical Summary

Problems solved by technology

During the inspection, a cystometry tube needs to be inserted from the urethral opening into the bladder for examination. At the same time, the urethral sphincter can control the closure of the urethra to prevent urine leakage. Sometimes it is also necessary to measure the pressure of the sphincter. The current cystometry tube cannot be the same pressure measurements of the bladder and sphincter muscles over time

The minimally invasive surgical treatment of benign prostatic hyperplasia, different patients and surgical methods, there are still patients with varying degrees of postoperative urinary incontinence, which greatly reduces the quality of life of the patients and increases the mental pressure on the clinicians
