Multifunctional drainage device for cutaneous ureterostomy

Abstract

The invention discloses a multifunctional drainage device for cutaneous ureterostomy. The device is made of a Pellethane-ether-based polyurethane multi-body, and comprises a drainage device tube bodywhich is spiral in appearance and of a hollow tube body structure, a drainage device large end which is arranged at the top of the drainage device tube body, is of a hollow tube body structure, is ina conical vortex shape and communicates with the drainage device tube body, a drainage device small end which is arranged at the bottom of the drainage device tube body, is of a hollow tube body structure, is in a conical vortex shape and communicates with the drainage device tube body, and a plurality of drainage side holes formed in the outer edge of the drainage device tube body at equal intervals in a penetrating manner. The device solves the problems that a ureter inner support is prone to being blocked, complications are prone to being caused and a tube is prone to retracting, and has the high practical value and popularization value in the technical field of surgical operation auxiliary materials.

Description

technical field [0001] The invention relates to the technical field of surgical operation auxiliary materials, in particular to a multifunctional drainage device for ureterocutaneous stoma. Background technique [0002] Ureterocutaneous ostomy is used in the treatment of bladder cancer, bladder neck obstruction, neurogenic bladder and other diseases. Because of its small trauma and good effect, ureterocutaneous ostomy is widely used in the treatment of urological diseases. During the operation, the ureter on one or both sides is pulled out of the body, the stoma is placed on the abdominal wall, and the ureteral stent is built in to drain the urine. However, because the ureter at the stoma passes through the abdominal wall, the ureter will be narrowed due to the compression of the abdominal wall tissue, so it takes a long time A ureteral stent is placed to ensure unobstructed drainage of urine. Since the ureteral stent is a foreign body, long-term indwelling in the renal pelv...

AI Technical Summary

Problems solved by technology

During the operation, the ureter on one or both sides is pulled out of the body, the stoma is placed on the abdominal wall, and the ureteral stent is built in to drain the urine. However, because the ureter at the stoma passes through the abdominal wall, the ureter will be narrowed due to the compression of the abdominal wall tissue, so it takes a long time A ureteral stent is placed to ensure unobstructed drainage of urine. Since the ureteral stent is a foreign body, long-term indwelling in the renal pelvis can lead to complications such as infection, empyema, and stones in the renal pelvis. The existing ureteral stent is prone to retraction into the ureter inside, cannot be taken out, and easily blocked
