Hermann Ultrasonics Inc. of Bartlett, Ill, has worked with medical company Genicon in Winter Park, Fla., to build one of the largest ultrasonic medical welding tools ever designed.
Genicon showed the part being welded — a new suction irrigation handle — at the Medical 2015 trade show in Germany. The device is used for liposuction.
The large size of the parts and their three-dimensional shape, it was a challenging application—especially the 12 millimeter difference in contour heights which needed to be matched by the contact surface of the weld tool, called a sonotrode.
Hermann Ultrasonics built an aluminum sonotrode measuring 220 mm by 180 mm.
The equipment maker has introduced the Medialog welder, for ultrasonic assembly in sterile environments. It is made of stainless steel and cleanroom-friendly surfaces and modified pneumatics. The Medialog has an FSC operator interface (Food and Drug Administration System Component), which meets the requirements of FDA CFR 21 part 11. FSC gives complete documentation of all actions performed by authorized users, and records time-stamped audit trails.
