Abstract
A follicle unit extraction system includes a generally tubular follicle punch having a distal cutting edge, and an ultrasonic transducer coupled to the punch to impart rapid, incremental, distally-directed cutting force pulses to the punch during the cutting operation. The punch is being mounted at the forward end of a handpiece, and the ultrasonic transducer is resiliently mounted within the handpiece and releasably coupled to the punch for imparting ultrasonic vibration to the punch.
Claims6
A follicle unit extraction system comprising
- a generally tubular follicle punch having a distal cutting edge, and
- an ultrasonic transducer coupled to the punch to impart rapid, incremental, distally-directed cutting force pulses to the punch during the cutting operation.
A method for cutting a follicle unit at a donor site prior to extraction comprising the step of applying ultrasonic vibratory cutting force against the tissue at the donor site during the cutting operation.
A method for cutting a follicle unit at a donor site prior to extraction comprising the steps of:
- bringing a generally tubular follicle punch having a distal cutting end region into contact with the skin at a donor site;
- inserting the punch distally into the skin in such a way that the follicle enters the punch's interior as the skin and underlying tissue circumscribing the follicle are cut;
- and
- applying ultrasonic, incremental, distally-directed cutting force pulses to the tissue via the punch during the cutting process.
