The present invention is an electrical slip ring device comprised of a stator, a rotor and an independent rotationally free brush ring. The brush ring may include a multitude of slipping fingers, chevrons or other current carrying structures that extend between the rotor and the stator. These current carrying structures have a directional bias or “lay”. The rotational freedom of the brush ring enables bi-directional movement of the rotor with reduced torque and wear at the sliding interfaces because sliding always occurs in the direction of the lay.

A mechanical link (100, FIG. 5), the mechanical link comprising a first arm (120), a second arm (140) and an interconnection member (160), wherein: the first arm is rotatable about a first axis of the interconnection member; the second arm is rotatable about a second axis of the interconnection member, the second axis being orthogonal to the first axis; and wherein: a flexible member (400) extends along the first and second arms and is adapted to accommodate rotation of the arms about the first and second axes, the flexible member having a single coiled portion (440) which is received within the interconnection member such that the coiled portion can coil and uncoil to accommodate rotation of the first arm, wherein the coiled portion is further configured to twist about an axis of the flexible member to accommodate rotation of the second arm.

The invention concerns a handle for a video endoscope including a housing and an interface portion rotatably supported relative to the housing where the interface portion includes a first connector element at its distal end section that is connectable to a second connector element of an associated elongate shaft of the video endoscope. Thereby a detachable, rotatable electrical and/or mechanical connection between the handle and the associated shaft is achieved. The coupling includes an electrical connection assembly arranged at an exterior of the interface portion forming an electrical connection to a stationary electric component of the handle. The handle includes a mechanical rotation stop for a rotation of the interface portion relative to the housing such that a rotation range is limited and damage to the electrical connection assembly is prevented.

A surgical instrument includes a slip-ring contact assembly. The slip-ring contact assembly includes an insulative housing defining a plurality of slots. A plurality of slip-ring contacts is operably supported in the insulative housing. Each slip-ring contact is configured to engage one or more electrical contacts formed circumferentially around a rotatable shaft of the surgical instrument. Each slip-ring contact includes a tang extending through a corresponding slot defined in the insulative housing and configured to be operably connected to an external wire connection. The plurality of slip-ring contacts is configured to allow unlimited rotation of the rotatable shaft while maintaining continuous electrical contact between each slip-ring contact and the corresponding electrical contact of the rotatable shaft.
