Intelligent in-situ implanted artificial bladder

Abstract

The intelligent in-situ implanted artificial bladder consists of urine conveying and storing system and automatic intelligent system, the former includes artificial ureter, artificial bladder body and artificial urethra; and the latter incldues pressure sensing alarm, automatic flow returning mechanisms, urine pump and controller. The present invention is used mainly for patient needling bladder reconstruction and urethra reformation owing to bladder tumor, necrotic and interstitial cystitis, traumatic bladder damage, etc. After the body's bladder is ablated, the artificial bladder is in-situ implanted into the pelvic cavityk, the artificial ureter is anastomosed with the ureter stump, the artificial urethra is anastomosed with the urethra strump, and the urine conveying and storing system is reconstructed. The present invention makes it possible for the patient to control urination time autonomously.

Description

(1) Technical field [0001] The invention relates to a medical artificial organ. Specifically, it is an intelligent model suitable for patients with bladder tumors, necrotizing and interstitial cystitis, severe tissue defects caused by bladder trauma, tuberculous bladder contracture and congenital deformities, etc., who need bladder reconstruction and urinary diversion. In situ implantable artificial bladder. (2) Technical background [0002] At present, permanent urinary diversion and bladder reconstruction mainly adopt ureterocutaneous ostomy and various intestinal replacement bladder operations. The disadvantages are as follows: 1. The incidence of infection is high, especially the retrograde infection from the ureter to the renal pelvis; 2. There are acid-base imbalances and electrolyte disturbances, such as hyperchloric acidosis, hypokalemia, and hypomagnesemia; 3. Malignant tumors may occur in the replacement bowel used; 4. Due to obstruction, urine reflux, residual ur...

AI Technical Summary

Problems solved by technology

Corresponding extracellular matrix and framework are attached to the inner layer of the urine delivery and storage system. After implantation in the body, urothelial cells can grow along the wall, thus successfully solving the problem of ureteral anastomosis due to granulation tissue hyperplasia and fiber wrapping. The resulting obstruction problem, thereby preventing hydronephrosis and effectively protecting renal function, can successfully solve the problem of urinary salt deposition and urolith formation caused by long-term contact of polymer chemical materials with urine
