Abstract: A substantially rectangular tool has a flat body, approximately 12 inches long and 6 inches wide, with a rasp surface on one side and a file surface on the other. The rasp portion of the tool includes a stop located near one of its narrower ends for abutting against the side wall of the hoof of a horse. This stop is provided as a reference and alignment point to measure the width of the hoof. The file portion on the other side of the tool includes measure markings for determining the width of the hoof being filed with reference to the stop. Both rasp and file portions have cutting edges placed at about 45 degrees with respect to the longitudinal axis of the tool. Two handles, a longer one for pushing the tool and a shorter one for controlling its position through each cutting stroke, are provided at each longitudinal end. In an alternative embodiment of the invention, a filing shoulder perpendicular to the cutting plane of the rasp is provided for trimming the side walls of the hoof.

Abstract: Equine sanitation apparatus includes a supply tube, and in succession on the tube, a nozzle at its distal end, a sponge, and structure for manipulating the apparatus, whereby the nozzle and the sponge may be inserted into a body cavity and the sponge manipulated therein, and liquid may be supplied to and exhausted from the body cavity via the tube and the nozzle. The preferred apparatus includes a syringe-type instrument for supplying liquid to the tube and exhausting the liquid therefrom. The apparatus advantageously is employed in a method for cleaning an equine sheath, wherein the nozzle and the sponge are inserted in the sheath, the sheath cavity is flushed through the tube and the nozzle to loosen and remove smegma therein, and the interior surface of the sheath is scrubbed with the sponge to break up crustaceous smegma for removal thereof.

Abstract: Pressure is applied to a loose skin region of the animal body by forming an elongated skin fold in the region and applying a clamp to the fold, such clamp including a pair of elongated clamping portions resiliently biased towards each other, and the clamping portions being disposed on opposite sides of the fold therealong and spaced inwardly from the outer margin of the fold so as to clamp the fold between the clamping portions and secure the clamp in place.

Abstract: An article of manufacture for use as an implant in the animal ear to correct a faulty carriage of the ear occasioned by the presence of a skin-enclosed cartilage fault comprises a spring constructed of non-porous biologically inert material, the spring having outwardly divergent arms terminating in outer free ends and adapted to be forced together to present a narrow elongated spring outline for implantation of the spring in the ear by insertion through a small incision in the skin of the ear with the free ends foremost and into a pocket previously formed between the skin and cartilage over a cartilage fault, so that the spring bridges the fault, the spring arms when free of applied force tending to return to their original divergent dispositions owing to the resiliency of the spring, whereby when the spring is implanted in the ear, the spring arms resist displacement of the spring towards the incision.

Abstract: An equine leg conformation is altered by bracing the hoof against shifting movement while standing on a supporting surface, wedging the hoof to tilt it with respect to the surface into an attitude which serves to provide a desired altered leg configuration, and altering the support for the leg to provide a hoof attitude in normal use equivalent to the aforesaid attitude. Apparatus for use in altering the leg conformation includes a base providing a supporting surface for the hoof, means on the base for bracing the hoof against shifting movement, and wedge means advanceable on the base in the direction of the bracing means for tilting the hoof with respect to the supporting surface into an attitude which serves to provide a desired leg conformation.

Abstract: A method of performing canine ear or other implantations in order to correct a faulty ear carriage by erection of the ear, utilizing three basic surgical pieces or implements in the form of (1) an elongated cut-forming shank (trocar) having a sharp distal end which is used to incise the ear so that the shank may be pushed along the general plane of the ear between the outer skin and the inner cartilage to create a duct which crosses over or bridges the weakened area of the cartilage, (2) an open-ended sheath (cannula) which is slidable onto the shank in close fitting relation and is adapted to be pushed into the duct as it is being created by the shank to the end that when the shank is withdrawn from the thus inserted sheath the latter remains within the duct and establishes an open-ended tunnel for reception of an ear-rigidifying implant, and (3) a pusher or thrust member which has a blunt forward end and is used to push the implant into the tunnel and consequently into the duct, and to hold it there while t
