Abstract
A cautery hook includes a proximal portion, a shank portion, and a distal hook portion. The shank portion is connected to the proximal portion at a bent knee protruding generally on a front side of the cautery hook. The distal hook portion is connected to the shank portion at an ankle protruding generally on a rear side of the cautery hook opposite from the front side of the cautery hook. The distal hook portion includes a distal hook tip generally on the front side of the cautery hook. The bent knee, ankle, and distal hook tip are the three most likely locations of contact between the cautery hook and a cannula sleeve when the cautery hook is passed through the cannular sleeve between an internal surgical site and the outside. Each contact tends to self-align the cautery hook to allow the hook to pass through the cannula sleeve without getting stuck or damaged.
