This is a simulation model for perfecting castration surgery in dogs. It is possible to simulate skin incision, fascia incision, ligation of spermatic cord and arteries and veins, removal of testicles and suturing. Both prescrotal and scrotal incision is possible. The weight is about 345g and the size is 11cm in length, 11cm in width and 8cm in height.

The model is based on a cartridge where only the contents can be replaced while the body remains the same, resulting in cost savings.
