Abstract:
A medical device, comprising:a substantially transparent head having a longitudinal axis and defining a substantially conical surface, an internal space, an opening at a base of the head, and a gap disposed at an upper surface of the head, the head comprising a first head half and a second head half, the first and second head halves being substantially symmetrical and contacting each other at least along a lower surface of the head when the head is in a closed position, the gap defined by portions of the first and second head halves that do not contact each other at the upper surface when the head is in the closed position; and a handle coupled to the lower surface of the head near the base of the head and extending substantially perpendicular to the length of the head, actuation of the handle causing angular motion of the first and second head halves about the longitudinal axis away from or toward each other, such that angular motion of the head halves away from each other to an open position enlarges the gap, the gap and the opening at the base of the head allowing an operator to insert one or more fingers into the internal space of the head at least when the head is in the open position.
