| 摘要 |
The invention relates to an instrument, particularly a medical device for minimal invasive surgery, that comprises an inflatable balloon (104) to which at least one movable tool element (105) is attached. In preferred embodiments, the tool element is a filamentary flexible structure like a wire (105) or an optical fiber. Moreover, a plurality of such tool elements is preferably arranged circumferentially around the balloon (104) constituting for example a cage-like grab that can be opened or closed by inflating or deflating the balloon (104). Furthermore, pulling a cord attached to the balloon (104) additionally allows to change the balloon configuration.
