摘要:
An ultrasonic surgical device capable of cutting biological tissues such as bone and cartilage. The ultrasonic surgical device includes a static casing, which sheaths an ultrasonic horn, and a lubrication film, which separates the ultrasonic horn and the static casing. The static casing, which also incorporates a plurality of fluid channels to allow passage of fluids along its length and eventual distribution of such fluids at the cutting end and biological tissue interface, inhibits the transfer of heat generated along the ultrasonic horn. The cutting end and the static casing are separated by a flexible joint, which serves to inhibit the transfer of vibrational energy, and consequently heat, from the cutting end to the static casing. As such, the static casing remains stable and can be used both to manipulate the surgical device with greater haptic control and facilitate effective penetration of larger cross-sections of biological tissue.
