Abstract: A rotatable endoscope coupler which enables an endoscope to be rotatably attached to a camera and selectively locked in place. The coupler enables single handed rotation of the scope while the camera remains in a fixed orientation. A plurality of ceramic ball bearings riding in a stainless steel race enable the coupler to be repeatedly autoclaved.

Abstract: A shock mounting system for a 3-chip video camera. The system comprises a prism mounting bracket with a pair of laterally spaced support legs. A standard 3 chip color camera is received between the support legs and a plurality of elastomeric plugs are molded to fit between the camera assembly and the housing within which it is situated. The elastomeric plugs are formed from flowable elastomeric material injected into molding chambers formed during the assembly process.

Abstract: A rocker switch on an endoscopic camera allows multiple functions from a single Hall effect sensor. The switch features a neutral position between a rocked forward and a rocked back position. When the front of the switch is depressed a dome spring under the front is flattened and the magnet located in the rear is moved away from the sensor. Releasing the switch returns it to the neutral position. Depressing the rear of the switch brings the magnet closer to the Hall effect sensor while depressing another dome spring under the rear of the switch. Again, releasing the switch returns it to the neutral position.

Abstract: A sheath is sized and configured to receive an endoscope. The sheath is provided with a housing having a proximally facing opening with a U-shaped notch. The endoscope has at the proximal end a right-angle light post which and is received closely within the U-shaped notch at the proximal opening of the sheath housing. A locking mechanism is provided including a pivotable latch having a distal end configured to be received within a notch formed on the endoscope housing distal to and diametrically opposed from the light post. The latch includes a spring tending to bias the distal portion thereof into engagement with the notch in the endoscope housing. A resilient O-ring is provided at the distal end of a recess in the sheath housing. A shoulder on the distal end of the proximal portion of the endoscope compresses the O-ring when the latch is engaged.
