Description
Technical Field
The utility model relates to the technical field of medical equipment, particularly, relate to a visual appearance of urethra and visual urethral catheterization device
Background
Catheterization is a technique frequently used in daily clinical practice, and some old male patients often need catheterization due to urinary retention caused by prostatic hyperplasia, or need to keep a catheter for a certain period of time for catheterization due to anesthesia after a conventional operation, or need to insert a catheter for urethral injury caused by traffic accidents, wounds and the like. Catheterization can adopt two methods, namely a direct catheterization method and a visual catheterization device, namely an endoscope-assisted insertion catheter.
The direct catheterization method is 'blind insertion', and medical personnel rely on the bending and the direction of feeling perception urethra through training and experience accumulation, directly insert the catheter catheterization in the bladder, and the shortcoming is: 1) the urethra environment cannot be observed, the operation technology needs experience accumulation, the learning curve time is long, and the failure rate is high; 2) it is easy to damage the urethra.
The visible urethral catheterization device is an endoscope-assisted insertion catheter, and clinically, a patient is usually pushed into an operating room, enters a bladder under direct vision through a ureteroscope or a cystoscope, is placed into a guide wire, and then slides the catheter into the bladder through the guide wire. The disadvantages of this approach are: 1) the equipment is heavy and inconvenient: because the ureteroscope or cystoscope used at present is a large instrument, is inconvenient to carry and is usually fixedly placed in an operating room, if a patient catheter fails, the patient needs to be pushed into the operating room to insert a catheter, so that the ureteroscope is not portable and is not beneficial to bedside rescue or a clinician; 2) the steps are complicated, and the consumed time is long: from the failure of the patient to catheterization to the procedure in the operating room, the involvement of doctors, nurses, anesthesiologists, transfer workers, etc. is time-consuming (at least 1 hour); 3) the equipment is expensive: a ureteroscope or cystoscope system (video acquisition, light source, display, ureteroscope or cystoscope) has the total value close to 50 ten thousand RMB, many primary hospitals lack such equipment, and the technical development surface is narrow; 4) the cost is high: when the ureteroscope or cystoscope is used for catheterization, at least 2 skilled urologists, 1 surgical nurse, 1 anesthesiologist and 1 transfer staff are required to be matched, the labor consumption cost is high, high-value consumables such as zebra guide wires are involved, and equipment depreciation is caused; 5) the technical threshold is high: ureteroscopy or cystoscopy, the catheter is placed, and the operation grading system belongs to II-grade operation and can be operated by more than the grade of high-annual capital attending physicians. The technology threshold is high, which is not beneficial to popularization and development.
