Model Using a Sock

Vasectomy Model Using a Wool Sock

This vasectomy practice model is based on the idea developed by Dr. Wayne Weissman, the vasectomist and teacher from Washington state and also of Guatemala fame. We owe Dr. Weissman our gratitude for the splendid idea behind this model.

This model uses a wool sock, some latex tubing, a Pennrose drain, and two plastic toy balls.

Follow the photos below to see how to construct the model.

latex tubing to imitate vasa in vasectomy scrotal model. the size that best replicates the feel of vasa is 1/8 inch outer diameter, 1/16 inch inner diameter, 1/32 inch wall.

Latex tubing and Penrose drain for vasectomy scrotal model. Cut the latex tubing slightly longer than the Penrose drain so you have enough tubing to tie knots to affix the balls.
