Abstract:

An applicator includes a barrel portion, a nose portion, a pivoting joint, a threaded screw, a cup, and a flexible driveshaft. The nose portion is connected to the barrel portion at the pivoting joint. The threaded screw is disposed in the barrel portion and threadably engages a plurality of threads. The cup is disposed in the nose portion and is adapted to carry a mass or instrument. The cup is rotationally fixed to the nose portion and the threaded screw such that rotation of the nose portion relative to the barrel portion causes axial displacement of the cup and the screw relative to the barrel portion. The flexible driveshaft extends between and is rotationally fixed to the threaded screw and the cup. The flexible shaft extends across the pivoting joint disposed at the connection between the nose portion and the barrel portion.
