An endoscope includes a body and a circuit board mounted within the body. A cable couples the circuit board to an imaging system. A common-mode choke is mounted within the body and is configured to electrically isolate the cable from the body at cautery frequencies. A method includes twisting a plurality of wires together to form a twisted set of wires. The twisted set of wires is wound around a core so that windings do not overlap, and so that a first winding and a last winding are separated from each other. Wires in the twisted set of wires are coupled to a plurality of wires in the cable. Also, these wires in the twisted set of wires are also coupled to the circuit board.

An imaging module includes an imaging element including a light receiving surface, an electrode surface on a side opposite to the light receiving surface, and imaging element electrodes formed on the electrode surface, a substrate including a first surface, a second surface on a side opposite to the first surface, and a first end surface facing the electrode surface, a cable portion having a conductor electrically connected to the imaging element electrodes via a wire on the substrate, a sealing resin that covers at least the first surface and the second surface, and an identification resin attached to a portion of the sealing resin on the first surface or a portion of the sealing resin on the second surface.

An imaging apparatus includes: an imager configured to generate an imaging signal; a transmission channel configured to connect a controller and the images; a superimposed signal generator that is arranged on a proximal end side of the transmission channel, the superimposed signal generator being configured to generate a superimposed signal by superimposing a pulsed data signal and a pulsed reference clock signal, and output the generated superimposed signal to the transmission channel; a first extractor that is arranged on a distal end side of the transmission channel, the first extractor being configured to extract the data signal and the reference clock signal from the generated superimposed signal; and a second extractor that is arranged on the distal end side of the transmission channel, the second extractor being configured to extract the negative voltage from the generated superimposed signal.

An endoscope system having: a transmission cable electrically connecting an actuator that moves an optical element along an optical axis direction and a driving signal generator for generating and supplying a driving signal for driving the actuator; a detector configured to detect magnitude of the driving signal output from the driving signal generator to be supplied to the actuator through the transmission cable; and a processor configured to supply the driving signal with an initial driving voltage value to the actuator for a predetermined time, calculate a combined resistance value including a resistance value of the transmission cable and a resistance value of the actuator, based on at least the detected magnitude of the driving signal, calculate a driving voltage of the actuator, based on the calculated combined resistance value and a preset rated current value of the actuator, and cause a storage to record the calculated driving voltage.

An apparatus of serializer/deserializer is provided. The apparatus comprises a holding unit and a capture unit. The holding unit connects to the capture unit through a coaxial cable, and comprises a disposable image-capture module, a synthetic-image module (L/R montage), a Mipi serializer, a Mipi deserializer, a Mipi capture card, and a capture device. Thus, the apparatus keeps the most expensive ISP and capture device at a back end; and puts the disposable image-capture module, the synthetic-image module, and the Mipi serializer at a front end. After use, it is only necessary to discard the disposable image-capture module, which extends into human body at the front end. The remaining parts are reused. Thus, cost is effectively reduced and the shortcoming of high cost of the use of modern disposable endoscope is solved.

Provided is a waveguide connecting structure of connecting a first waveguide to a second waveguide, or to a transmitting and receiving device. The waveguide connecting structure included: an elastic body configured to cause an external conductor to closely contact a dielectric body, the external conductor and the dielectric body being included in the first waveguide, the external conductor covering an outer periphery of the dielectric body; and a three-dimensional body configured to hold the dielectric body, and the second waveguide or the transmitting and receiving device, the three-dimensional body having electric conductivity inside an insertion hole holding the first waveguide, and the external conductor of the first waveguide including a radially spread portion that has been radially spread, the radially spread portion being where the first waveguide and the three-dimensional body are connected to each other.

An in-vivo camera device and an in-vivo monitoring camera system more excellent in usability are proposed. An in-vivo camera device includes a camera unit introduced into a body, a support member, and a camera-side cable. The support member has a trocar connection portion for connection with a trocar at a front end side, and is connected to the trocar in a state in which the trocar connection portion is fitted into the trocar by applying tensile force to the camera-side cable passing through the trocar. The support member is provided with a guide introduction portion that is formed to be relatively long at the front end side as a stabilization structure for stabilizing connection with the trocar.

Endoscopic devices are disclosed for viewing and/or performing a surgery on a patient's organ, such as a uterus. In an embodiment, the endoscopic device includes a housing, a cannula, an imaging system, and a flexible printed circuit (FPC). The cannula is configured for insertion through a cervix into a uterus. The cannula has a lumen that extends from a proximal end of the cannula to a distal end of the cannula. The proximal end of the cannula is secured within the housing. The imaging system is located at a distal end of the cannula and includes a camera and one or more light-emitting diodes (LEDs). The FPC extends within the lumen of the cannula and electrically connects the camera and the LEDs to electrical components located in the housing. The lumen is configured to provide a passage for a working tool.

A tethered imaging camera encapsulated in a shell lens element of such camera enables viewing from inside and imaging of a biological organ in/from a variety of directions. A portion of camera's optical system together with light source(s) and optical detector mutually cooperated by housing structure inside the shell are moveable/re-orientable within the shell to vary a desired view of the object space without interruption of imaging process. A tether carries electrical but not optical signals to and from the camera and controllable traction cords to move the camera, and a hand-control unit and/or electronic circuitry configured to operate the camera and power its movements. Method(s) of using optical, optoelectronic, and optoelectromechanical sub-systems of the camera.

Medical borescopes and related methods. In some embodiments, a medical borescope may comprise a handle and a tube extending from the handle. The tube may be partially, or wholly, defined by an at least substantially non-conductive material, such as a suitable plastic, ceramic, or other non-metallic material. The borescope may further comprise a tip assembly positioned at a distal end of the tube, which may comprise an image sensor configured to take images through the distal end of the tube.
