Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: A surgical instrument includes a rotatable electrical coupling assembly having a first part and a second part that electrically couple and rotate relative to each other. The second part is carried by and rotates with a tube collar coupled to a transducer. A portion of the transducer is inserted through an aperture of the second part, but does not contact the second part. The first part of the assembly may electrically couple to the second part via pogo pins, brush contacts, or ball bearings. Alternatively, the first part may comprise conductive channels formed in the casing. The second part may comprise a rotatable drum with a conductive trace. In some versions, one or more components may comprise MID components. In another version, the rotatable electrical coupling assembly comprises a rotatable PC board and brush contact. Further still, a circuit board may be provided with the transducer inside a transducer casing.

Abstract: Single networkable fault monitoring system for monitoring electrical parameters on at least one electrical phase on at least one interconnected electric chain hoist for various fault conditions. When at least one fault signal is generated, at least one kill signal is generated in the fault monitoring system, causing generation of at least one kill function in at least one chain hoist motor controller. The generated kill function causes a power disconnection to all connected electric chain hoists and/or the entire network of fault monitoring systems. When a fault has been generated, each individual fault signal outputs fault specific diagnostic data from the fault monitoring system to help an operator identify the fault specific electric chain hoist(s) and the specific fault type(s). This data is intended for the purpose of interfacing with an operator monitoring device, LED indicators, data logger, and/or any other user-defined application or combination thereof.
