CYCLICAL ANASTOMOSIS DEVICE FOR URINARY BLADDER

摘要

Cyclical anastomosis device for urinary bladder that will be used for the anastomosis of the back of the urinary bladder and the urethra in the open, laparoscopic and robotic radical prostatectomy that consists of the main two sections, section A and section B. Section A consists of: a stopcock 1.2 with a metallic bar 1.8 that ends to the metallic guide 1.1, two propulsion levers 1.3 that are connected to the carrier of the metallic clips 1.4 and the cyclical metallic knife 1.5, external cover 1.6 and a handle cover 1.7. Section B consists of: a stopcock with a metallic bar 2.2, a metallic guide 2.1, metallic receptors of clips 2.3, two flexible retaining rings of the receptors of clips 2.4, external cover of the bar from a silicone membrane 2.5 and an operating bearing 2.6. The main section A is inserted from the incision of the urinary bladder and the main section B that has smaller diameter is inserted from the external nozzle of the urethra and after they pass through the coloboma of the back of the urinary bladder and the coloboma of the urethra respectively, they are connected to one another, the diameter of the two sections is equivalent and by a motion of the propulsion levers 1.3 they achieve to perform the anastomosis of the urinary bladder with the urethra in the open, laparoscopic and robotic radical prostatectomy. The advantages of this invention is that by the cyclical anastomosis device for urinary bladder the following are achieved: 1. Better quality of anastomosis. 2. Less bleeding. 3. Less surgical time. 4. Great facility for the surgeon and specifically during the laparoscopic and robotic radical prostatectomy. 5. Less hospitalization time. 6. Less possibility of stenosis of the urethra at the point of anastomosis.
