A jet injector is used to shoot a very fine stream of anaesthesia that numbs the skin and penetrates it to a depth of 5 mm, which is sufficient to surround and freeze each tube (vas deferens) when these are immobilized under the numbed skin.
While the anaesthesia takes hold, the scrotum is cleaned and wrapped in a sterile manner.
The tube is manipulated into position just under the numbed skin.
It is immobilized under the skin with a holding clip; tissues are then delicately separated to reach the tube.
The tube is brought to skin level.
The upper cut end of the tube is cauterized (burnt) to make it close up through scarring.
A tiny titanium staple is then put in to ensure the ends of the tube are separated by a layer of tissue.
No stitching is required and the small opening closes up within a day.
