Abstract: A lead puncture needle includes a core rod, a puncture needle, a lead mechanism and a handle. A front end of the core rod includes a blunt head and a lead slot. During puncture, the puncture needle is exposed. After the puncture, the blunt head protrudes out of the puncture needle to avoid injury to normal tissue. When a button is pressed, the core rod moves downward, and the lead slot protrudes from the puncture needle. When the button is pressed again, the core rod moves upward, and the lead slot is retracted into the puncture needle to form traction on a surgical suture. The design of the blunt head ensures that it is retracted during puncture to expose the puncture needle to facilitate puncture and the blunt head is controlled to be exposed outside the puncture needle in a separation process, thereby avoiding accidental injury to the surrounding tissue.

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.

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.
