20160184615 | Sonotrode - The invention relates to a sonotrode for an ultrasonic surgical instrument. The sonotrode comprises a shaft and an instrument head, which is located at a distal end of the shaft. A removal structure is arranged on the instrument head. A channel extends inside the shaft from an outlet opening on the instrument head to a channel opening. According to the invention, the channel opening is arranged in the circumferential surface of the sonotrode. Provision is additionally made that, in the area of the channel opening, an attachment part with a liquid connection is provided. By virtue of an attachment part being provided in the area of the channel opening, a rinse hose can be connected directly to the liquid connection of the attachment part, such that the hand part no longer comes into contact with the rinsing liquid. The cleaning work is thereby reduced. | 06-30-2016 |
