An anastomotic aid for bladder cancer and prostatectomy for bladder and urethra reconstruction

Abstract

The invention provides a vesicoureteral reconstruction anastomosis assistor for radical operation of bladder cancer and prostate cancer. The assistor comprises an outer sleeve, an airbag and a sutureguide pin and is characterized in that the airbag is arranged at the front end outside the outer sleeve, and an inflating channel communicating with the airbag is arranged in the outer sleeve; the rear of the inflating channel is connected with an inflating valve; the suture guide pin is arranged in the outer sleeve, and the front end of the suture guide pin can extend out of the outer sleeve; therear end of the suture guide pin is connected with a boosting structure capable of enabling the suture guide pin to move forward and backward; the front end of the outer sleeve and the boosting structure is provided with a curved section corresponding to a urethra bend; and an active structure comprises a rod-shaped structure and a boosting button which is connected with the rod-shaped structureand moves along a sliding chute, or a pressing and lifting button which is connected with the rod-shaped structure and can be pressed and lifted. By repeatedly operating the boosting structure, the suture guide pin is extended and retracted to achieve the purposes of effective assistance of urethra anastomosis and no interference on urethra reconstruction. The assistor provided by the invention isreasonable in instrument structure and simple and convenient in operation.
