摘要:
Described are embodiments that include a device with a motor that when connected to a cannula rotates the cannula while removing adipose tissue from a surgical site. The device provides a direct pathway, for aspirated adipose tissue, from a tip of the cannula to a location where tubing is attached to the device. The pathway does not pass through the motor that provides the angular rotation of the cannula. Instead, the path for the adipose tissue passes through a removable coupler that is connected to the cannula. The embodiments provide a cannula that rotates but also has a direct flow path for adipose tissue that does not pass through the motor.

Described are embodiments of a canister, system, and method of filtering fat. Embodiments include a sidewall that defines a volume, a filter with a screen, a first port, a second port, and at least one vane which allows for manual agitation of lipoaspirate within the volume. The first port is used to draw fluid from below the filter, forcing excess fluid in the lipoaspirate to be quickly extracted. The vane allows the lipoaspirate to be repeatedly drawn over the filter to aide in removing of liquids from fat in the lipoaspirate. The treated fat may then be removed from the volume through an outlet port and reinjected into a patient.

Described are embodiments including methods and devices for venting a handpiece of a medical device. These embodiments provide a vent for the handpiece. A porous membrane is positioned over an opening of the vent to allow gas, including steam, to enter and escape from the handpiece and prevent liquids from entering the handpiece. Other embodiments include methods and devices for holding an ultrasonic driver assembly within a handpiece and preventing the ultrasonic driver assembly from rotating within the handpiece. These embodiments include positioning the ultrasonic driver assembly such that the ultrasonic driver assembly is held in place at a node of the ultrasonic driver assembly and an anti-rotation mechanism is also located at the node.

An actuator for at least translationally or linearly moving an object from a first position to a second position displaced from the first position is disclosed. In one embodiment, the actuator includes a strip of shape memory alloy configured as a coil wound about a first rotatably-fixed member, the strip having first and second end portions, the first end portion being interconnectable to the first rotatably-fixed member and the second end portion being operatively associated and/or interconnectable with the object to be moved, and a heating assembly adapted to heat at least a portion of the strip of shape memory alloy from a first temperature corresponding to the strip being in a martensitic state to a second temperature corresponding to the strip being in an austenitic state, the second temperature being above a martensitic/austenitic transformation temperature of the shape memory alloy. Such heating of the strip to the austenitic state results in at least radially-outward and arcuate movement of the second end portion of the strip which, in turn, may move the object translationally.
