A powered handpiece for imparting to a cannula of a medical device a reciprocal movement of amplitude (x) along a longitudinal axis (X) is provided. A housing (1) at least partially encloses a hollow tube (2) extending along the longitudinal axis (X) between an inlet end (2i) and an outlet end (2o), the inlet end (2i) being configured for coaxially coupling the hollow tube (2) to a hollow cannula (10). A ring (3) rigidly is coupled to the hollow tube (2) and has an opening (3o) defined on a plane (X, Y), having a length, L, YX. A cam (4) mounted on a rotation axle (4r) parallel to a second transverse axis (Z) normal to the plane (X, Y) (i.e., XYZ), offset from a centroid (C) of the cam on the plane (X, Y) by a distance (P), and set at a fixed position relative to the housing (1), the cam being engaged in the opening (3o).

A vibrating hand held surgical instrument for loosening tissue of a patient for liposuction or body contouring procedures. The instrument includes a motor connected to a vibration actuator having an eccentric rotating mass and an end effector for engaging tissue operatively connected to the vibration actuator, wherein the motor rotates the eccentric mass to cause the end effector to vibrate to loosen tissue. A flexible shaft having first end and second ends dampen the vibration to the motor and to the operator handle.

An improved system and method for performing liposuction and autologous fat transfer is provided. The present invention comprises an improved lipoaspirate collection canister and multiple devices wirelessly and operably connected to one another, including a digital regulator box and wireless triple pedal unit for control of the system components. A liposuction handpiece is operably connected to the system devices, and a custom quad tubing is operably connected from the handpiece to the components of the system and supplies and/or removes fluids, fat tissue, compressed air, suction, and/or power for the procedure. The method disclosed herein includes using vibration to deliver tumescent fluid to a patient as well as to break up and remove fat tissue from a patient. During the fat preparation step, a vibrational plate is used to effectively and efficiently separate the lipoaspirate prior to transferring the fat tissue into the patient.

A guide device for cannulas for the collection of micro-fragmented subcutaneous adipose tissue includes a handle which has an axial cavity intended to house a syringe equipped with a collection cannula. The axial cavity has an open proximal end, an open distal end and a central axis. A lip protrudes cantilevered from the distal end at a distance from the central axis and from said cannula. An intermediate anti-flexion element of the cannula is arranged between the handle and the lip.
