The tubal ligation instrument of the present invention includes structure for ligating anatomical tubes within the human or animal body, and structure for anesthetizing the anatomical tubes being ligated. An example of an anatomical tube is a Fallopian tube. The instrument further includes a structure for grasping the anatomical element. The grasping structure extends through a channel in the instrument housing. Usually the grasping structure is a rod having forceps tongs at one end with a flat surface formed on a side portion of the rod. Consequently, the rod does not occupy the entire housing leaving a channel between the rod and the housing. On an outside surface of the instrument housing is an anesthesia receiving means, typically a stopcock. A channel through the stopcock, through which anesthesia may flow, is capable of communicating with the channel between the rod and the housing. The application of anesthesia to an anatomical element is accomplished by introducing the anesthesia through the stopcock and into the unoccupied channel of the housing. Thus, a surgeon directing the end of the instrument to an anatomical element can apply an anesthetic agent to the anatomical ele…
