Abstract: A nail extractor advances a spinning drill tube into wood closely around the head of a nail to be extracted. As the drill tube advances into the wood around the nail, it compresses a drilled core of wood between the nail and the inside of the drilling tube. As this compressed core of drilled wood deepens or lengthens, it engages and rotates the nail, spinning the nail free from the wood in which it has been embedded. The spinning drill tube can then be removed with the nail and the compressed core of drilled wood, without touching the nail with the extractor tool. The nail is then preferably ejected from the drill tube by advancing an ejector pin into the drill tube.

Abstract: A surgical process for removing the third phalanx of a feline, and most commonly a housecat, while reducing bleeding, swelling, pain and tissue deficit. A circumferential incision is formed on the epidermis of the ungual crest and traction is applied to the epidermis in a cranial direction. This exposes the extensor tendon and synovium, which are incised by the laser from a dorsal position aimed in a palmar direction. While applying traction to the third phalanx in a palmar direction, the collateral ligaments are ablated, permitting further disarticulation of the PII-PIII joint. Finally, the flexor tendon and tissue of the pad are incised by the laser from a dorsal position, permitting removal of the third phalanx. The declaw site is then covered with the redundant epithelium preserved in this process.
