Disclosed herein are safety devices that are positioned on the end of a fiberoptic cable, such as those used in surgical procedures, to prevent patients and other objects from the risk of burn from light or heat emitted from the end of the cable when not connected to an optical instrument. The disclosed safety devices can be added to the ends of existing cables and/or can be included at the end of cables during manufacture. In some embodiments, the safety device replaces an existing connector at the end of a cable, and in some embodiments the safety device is added in addition to a connector at the end of the cable. In some embodiments, a slit end cover is included over an open end of an adaptor that is mounted on a distal connector of a fiberoptic cable.

An endoscope apparatus capable of transmitting an endoscope image as an optical signal includes: an electronic component that includes a reception circuit configured to receive an electric signal outputted from an image pickup device and supply the electric signal to a conversion device; a printed board provided with the electronic component; a shielding member that covers at least the reception circuit; a first path via a ground connection line that is provided for the electronic component, and electrically connects the shielding member to a ground; and a second path via a conductive portion that electrically connects the shielding member to the ground, wherein an impedance of the second path is lower than an impedance of the first path.

The present disclosure provides a common-path optical waveguide probe. The common-path optical waveguide probe includes an optical waveguide, a lens, and a reference reflector. The optical waveguide includes a proximal end and a distal end. The lens is coupled to the distal end. The reference reflector is positioned between the optical waveguide and the lens. The disclosure also provides a catheter and an optical coherence tomography system utilizing the common-path optical waveguide probe. The disclosure also provides methods of making and using the common-path optical waveguide probe.

The disclosure relates to diagnostic, surgical, and/or therapeutic devices for being introduced into the human or animal body or for in vitro examination of human or animal blood samples or other body cells, in particular to an endoscope or a disposable endoscope that includes at least one illumination light guide and/or image guide for transmitting electromagnetic radiation, the illumination light guide or image guide having a proximal end face for incoupling or outcoupling of electromagnetic radiation and a distal end face for incoupling or outcoupling of electromagnetic radiation. The proximal and/or distal end faces consist of plastic elements that are transparent at least partially or in sections thereof, the transparent plastic being biocompatible and/or having non-toxic properties to human or animal cell cultures for exposure durations of less than one day. This allows for the production of assemblies for disposable endoscopes, inter alia.

In a surgical robot, a robot controller controls an articulated robot so that an arm base rotationally moves in an arc shape around a predetermined position set at a position away from the arm base.
