Input attachment, surgical device, arrangement for intraoperative use and use of an input attachment

An arrangement for intraoperative use, wherein the arrangement comprises:

• at least one input attachment (1), comprising an input device (4) which is configured to receive a user input;
• a control device (5) which is configured to generate a control signal for controlling the surgical handpiece (2) from the user input received,
• an electrical interface (6) through which the control signal generated is transmitted to the surgical device (3), and
• a mechanical assembly interface (7) which is configured to form a non-slip connection with the surgical handpiece (2) in the assembled state of the input attachment (1) in such a way that the input attachment (1) assembled with the surgical handpiece (2) can be handled as a one-piece handpiece;
• a surgical device (3) 26, comprising a first electrical device interface (10) having a first interface (10) and a second interface (11),
• wherein the first interface (10) is configured to receive control signals from the input attachment (1) coupled to the surgical device (3) via the electrical device interface, and
• wherein the second interface (11) is configured to transmit stimulation signals based on the control signals received to a surgical handpiece (2) coupled to the surgical device (3) via the electrical device interface (9);
• and
• the surgical handpiece (2).
