Abstract
Abstract An ultrasonic lipectomy probe device comprises, in accordance with the present invention, a shank having a proximal end and a distal end, a connector at the proximal end of the shank for connecting the shank to a source of ultrasonic vibrational energy, and an enlarged head at the distal end of the shank. The probe head has a width, in a first direction, substantially larger than an outer diameter of the shank at the distal end thereof. In addition, the head has a thickness, in a second direction essentially orthogonal with respect to the first direction, substantially equal to the outer diameter of the shank. Accordingly, the probe head is flattened, for facilitating the removal of fat in accordance with the present invention. In most applications, the shank is provided with a longitudinally extending channel, while the head may be provided with a pair of inlet bores communicating with the channel and extending at substantial angles to the channel on substantially opposite sides thereof.
