Urethral catheterization assistance device for transurethral resection surgery for bladder tumor

Abstract

The invention relates to the technical field of medical devices, in particular to a urethral catheterization assistance device for transurethral resection surgery for bladder tumor. The device comprises a catheter and an assistance mechanism for coordinating with the catheter in insertion. The catheter comprises a flushing cavity and a drainage cavity which are two completely separated cavities bya partition, a flushing cavity inlet and a flushing cavity outlet are formed in two ends of the flushing cavity respectively, and a drainage cavity inlet and a drainage cavity outlet are formed in two ends of the drainage cavity respectively. An internal capsule and an external capsule are arranged on the catheter, an opening is formed in a position, corresponding to a cavity of the inner capsule, of the catheter, and the opening is connected to the tail end of the catheter through a hose. The device can effectively prevent blood stasis in the bladder, clears an ideal operation field for surgeons, and facilitates rapid electrocoagulation of a bleeding position in the bladder base or villi; and the bladder can be cleaned at any time, repeated intubation for catheterization and cleaning isprevented, and injuries and infection to urethrae are prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheterization auxiliary device for transurethral resection of bladder tumors. Background technique [0002] Clinically, bladder tumor is a common disease of the urinary system, and its incidence ranks in the forefront of urinary system tumors. The main treatment method is surgery or surgery combined with postoperative bladder infusion chemotherapy. Transurethral resection of bladder tumor (Transurethralresection of bladder tumor, TURBT) is a treatment method for superficial non-invasive tumors of the bladder. It is a very good treatment method for bladder tumors. It has the advantages of almost no operative mortality, and can preserve bladder voiding function. This method is usually a combination of diagnosis and treatment, which can avoid or reduce open bladder surgery. [0003] In the existing transurethral resection of bladder tumors, bleeding problems may be cau...

AI Technical Summary

Problems solved by technology

[0004] 1. In this case, when there are many blood clots in the bladder, it is difficult for the operator to find the bleeding location in the base layer or in the villi. The blood may flow back into the urethra through the neck of the bladder, and the blood clots may also adhere to the outer sheath or lens of the resectoscope, affecting treat

[0005] 2. Most of the existing urinary catheters can only be used for urinary catheterization and do not have the function of cleaning the bladder, resulting in the need for multiple / repeated intubation for patients, which is likely to cause problems such as urethral damage and infection
