Abstract: A surgical system comprises a first element with a seat (19) which removably receives a surgical instrument (14) for operational use thereof. The seat (19) is provided with at least one first electrical connector (25) which is intended for electrical connection with a complementary second electrical connector (26) present on the instrument when the instrument is mounted in the seat. At least one of the two said connectors (25, 26) is designed to be movable controllably between a first retracted rest position and a second advanced position for electrical connection together with the other connector and is provided with electrical contacts for engagement in the other connector which are suitable for perforating, during the movement between the first and second positions, at least one sterile sheath (18, 24) which is arranged between the first and second connectors.

Abstract: Wheel for pedal-assisted bikes includes: a fixed structure associable with the frame of a bike having a driving pedal crank; a circle element mounted on the structure for rotation around a main rotation axis; a propulsion disc rotatably mounted on the structure and connectable to the crank; an electric motor associated with the structure and for cooperating with the propulsion disc to motorize the circle element; and transmission elements for transmitting rotary motion from the disc to the circle element which include a first detection device for detecting the force transmitted to the circle element from the disc, and including: a first plate associated in rotation with one of the disc and the circle element; a second plate associated with the other of the disc and the circle element; at least a motion transmission part between the first plate and second plate.
