Abstract:
1. A method of fragmenting and removing adipose tissue from a surgical site using a cannula and a removable coupler connected to the cannula, the method comprising: connecting a portion of the cannula to a cavity in a distal end of the removable coupler; aspirating the adipose tissue from the surgical site with vacuum through a channel of the cannula that is coupled to a first end of a channel of the removable coupler to provide a pathway for flow of the adipose tissue into tubing coupled with a second end of the channel of the removable coupler; venting the cannula through a plurality of venting channels defined in the interior walls of the cavity; collecting the adipose tissue in a container coupled by the tubing with the second end of the channel of the removable coupler; and during the aspirating, rotating the cannula using a motor connected to the removable coupler and the cannula, wherein a central axis of the motor is adjacent a central axis of the removable coupler so that the pathway does not pass through the motor.
