摘要：
An instrument including a grip portion, a first substantially rigid extension arm projecting outwardly from the grip portion along a first longitudinal axis, and a second substantially rigid extension arm projecting outwardly from the grip portion along a second longitudinal axis. The first has a straight portion adjacent the grip portion that lies substantially within a first plane, and a distal portion extending from the straight portion to a first distal end along a length of which the first extension arm extends upward relative to the first plane and rotates about its first longitudinal axis. The second has a second straight portion adjacent the grip portion that lies substantially within the first plane, and a second distal portion extending from the straight portion to a second distal end along a length of which the second extension arms extends downward relative to the first plane and rotates about its longitudinal axis.
