The drill comprises dual lumen-forming members (206) that are movable in a pincher-like fashion and a shaft (202) with a proximal handle (204). Each lumen-forming member comprises an arm (210) with a lumen-forming tip (212) at one end and is rotatably connected to the shaft at about the distal end of the shaft by a pivot pin (220). Each lumen-forming member is also joined to a control rod (224) by a link member (226) with pivot pins (228, 230). The control rod runs through the shaft and connects to an actuator (222) preferably with threads.
