  • Publication number: 20250224059
    Abstract: An apparatus includes a port body for holding a first device and a retainer for retaining the port body. The port body includes a base, a stem extending from the base, and one or more first anti-rotation members disposed at the base. The retainer includes first and second retaining members, with the base of the port body disclosed in between. A through-hole larger than the stem of the port body is formed at the first retaining member, allowing the stem to pass through and to move relative to the first retaining member. One or more second anti-rotation members are disposed at the first or second retaining member and coupled with the one or more first anti-rotation members. The retainer restricts the port body from rotating but allows it to move translationally relative to the retainer to accommodate axial misalignment when connecting the first device with a second device.

  • Publication number: 20250224060
    Abstract: An apparatus includes a first coupling member for receiving a first device and a second coupling member connected to or formed with the first coupling member at a proximal end portion of the first coupling member. The second coupling member includes a revolving exterior surface having a first revolving segment proximal to the first coupling member and a second revolving segment distal to the first coupling member. Each of the first and second revolving segments of the revolving exterior surface has a first side and a second side that is narrower than the first side. The second sides of the first and second revolving segments of the revolving exterior surface face each other. The revolving exterior surface is automation-compatible and operable by a robotic arm, facilitating automation of the first device.
