ABSTRACT:
An implanter by which pelleted drugs can be inserted or implanted under the skin of an animal typically to promote fattening of beef cattle and the like. The device includes a thurst pin which can be pushed through a tube containing the pellets to eject them into and through a hollow needle at the front of the device. A mechanism acts on the pin to push it in the forward direction and a return spring acts to return it to its rest position.
The mechanism includes a trigger lever as part of a handle assembly and movement is transmitted to the pin through a flexible link such as a cord or wire or belt or chain. The latter passes around abutments so as to reverse the direction of movement so that the pin is effectively pulled in the forward direction, the link being attached to a shuttle to which the rear of the pin is attached. A velocity ratio of for example 1:2 is employed so that the pin travels (in the case of that velocity ratio) twice the distance that the trigger lever travels thus enabling the device to be held and operated in one hand.
The tubes may be inserted one at a time in one embodiment. In other embodiments the tube-receiving region of the device is adapted to accept an array of tubes joined together to form a magazine typically in the form of a flat pack in which they are side by side or in the form of a cylinder.
