The handling device includes a detection device to detect the presence of a workpiece and to determine a pressure of the working fluid. The piston has a vertically movable holding magnet that faces the housing bottom for holding the workpiece. The holding magnet controls a valve arrangement of the detection device.

    Abstract: This disclosure may disclose, inter alia, devices, systems, and methods for cleaning or removing contamination from a lens, or for increasing visibility of a lens during surgery. For example, a device with a handle actuated element is disclosed. The device includes a shaft that includes a rod, an element coupled to a distal tip of the rod, and a handle coupled to a proximal end of the rod. Actuation of the handle into a first position may cause the handle to be configured in a substantially hexagonal shape and may cause deployment of the element from the shaft. Actuation of the handle into a second position may cause the handle to be configured in a substantially rectangular shape and may cause retraction of the element into the shaft. The device may be introduced into an abdomen, and an element on the device can be deployed during surgery.
