摘要
A surgical instrument for easing the anastomosis of the urethra in laparoscopic prostatectomy comprising a cannula (1), suitable for being inserted into the urethra from the penis until it reaches the resection point downstream of the prostate with its distal end (1a), and equipped with radial openings (5) close to the distal end, and a plurality of needle-shaped elements (7) housed in the cannula close to the distal end and suitable for projecting for a controlled extent through the radial openings to transfix the urethra anchoring it to the cannula. Means (8, 10, 20) are foreseen for moving the needle-shaped elements (7) from a position completely retracted in said cannula to a position projecting from it so that it is substantially inclined forwards. In this way, the surgeon can actuate said means from the proximal end of the cannula to make the needle-shaped elements project from the radial openings adjusting the amount that they project up to the transfixion of the urethra, for whereby the retraction of the remaining stump of urethra can be avoided.
