Abstract: An instrument for grasping and incising the scrotum of an animal. The instrument has a barrel, a spring-loaded rod within the barrel, a pair of forceps members attached to the rod and a knife housing with a spring-loaded knife at the forward end of the barrel. A spring-biased latch member is provided to hold the knife in a cocked position. A trigger is attached to the barrel to cock the rod in a forward position with the forceps members extending forward through the knife housing and to release the rod for rapid movement rearward in the barrel. With the knife and rod cocked, the forceps members are applied to the scrotum of an animal. The trigger is then pressed to release the rod and forceps members rearward. The rearward movement of the forceps members draws a portion of the scrotum into the knife housing behind the knife. The final rearward movement of the rod causes the latch member to be tripped, and the knife is released to incise the scrotum.
