A dermatome assembly is operable to harvest a skin graft and includes an ultrasonic dermatome and a power supply. The ultrasonic dermatome includes a body and an ultrasonic blade assembly mounted in the body. The blade assembly includes a frequency generator and a cutting horn powered by the frequency generator. The cutting horn is spaced apart from the body so that the body is restricted from damping vibrational movement of the cutting horn. The dermatome assembly is operable to precisely control the thickness of the cut skin graft and also restrict the cutting hom from overheating.

La présente invention concerne un ensemble dermatome utilisé pour prélever une greffe de peau, qui comprend un dermatome à ultrasons et une alimentation en énergie. Le dermatome à ultrasons comprend un corps et un ensemble lame à ultrasons monté dans le corps. L'ensemble lame comprend un générateur de fréquence et une corne tranchante alimentée par le générateur de fréquence. La corne tranchante est espacée du corps de manière à ce que le corps n'amortisse pas le mouvement vibratoire de la corne tranchante. L'ensemble dermatome peut être actionné pour précisément contrôler l'épaisseur de la greffe de peau coupée et empêcher la surchauffe de la corne tranchante.
