A handpiece system comprising: an ultrasonic handpiece comprising: a vibration source configured to produce a plurality of ultrasonic vibrations; and a horn configured to transform the vibrations into ultrasonic motion; and a spatula coupled to the horn and configured to move according to the ultrasonic motion, the spatula comprising a spatula handle having a central axis and a blade, the blade comprising a proximal portion extending from a distal end of the spatula handle, and a blade tip portion extending from a distal end of the proximal portion, wherein: a central axis of the proximal portion has a bend with a bend angle (θ bend) that is between zero and 30 degrees relative to the central axis of the spatula handle; a central axis of the blade tip portion has an angle (θ blade) between 20 degrees and 60 degrees relative to the central axis of the spatula handle; the blade tip portion having a tip angle (θ tip) of 20 to 70 degrees, the tip angle (θ tip) representing the angle between surfaces of the blade; and wherein the ultrasonic motion comprises a longitudinal motion which is substantially parallel to the central axis of the spatula handle, characterized in that surfaces of the blade meet at a distal end of the blade so as to form an edge, the edge being substantially perpendicular to the central axis of the spatula handle. an ultrasonic handpiece comprising: a vibration source configured to produce a plurality of ultrasonic vibrations; and a horn configured to transform the vibrations into ultrasonic motion; and a vibration source configured to produce a plurality of ultrasonic vibrations; and a horn configured to transform the vibrations into ultrasonic motion; and a spatula coupled to the horn and configured to move according to the ultrasonic motion, the spatula comprising a spatula handle having a central axis and a blade, the blade comprising a proximal portion extending from a distal end of the spatula handle, and a blade tip portion extending from a distal end of the proximal portion, wherein: a central axis of the proximal portion has a bend with a bend angle (θ bend) that is between zero and 30 degrees relative to the central axis of the spatula handle; a central axis of the blade tip portion has an angle (θ blade) between 20 degrees and 60 degrees relative to the central axis of the spatula handle; the blade tip portion having a tip angle (θ tip) of 20 to 70 degrees, the tip angle (θ tip) representing the angle between surfaces of the blade; and wherein the ultrasonic motion comprises a longitudinal motion which is substantially parallel to the central axis of the spatula handle, a central axis of the proximal portion has a bend with a bend angle (θ bend) that is between zero and 30 degrees relative to the central axis of the spatula handle; a central axis of the blade tip portion has an angle (θ blade) between 20 degrees and 60 degrees relative to the central axis of the spatula handle; the blade tip portion having a tip angle (θ tip) of 20 to 70 degrees, the tip angle (θ tip) representing the angle between surfaces of the blade; and wherein the ultrasonic motion comprises a longitudinal motion which is substantially parallel to the central axis of the spatula handle, characterized in that surfaces of the blade meet at a distal end of the blade so as to form an edge, the edge being substantially perpendicular to the central axis of the spatula handle.
