An endoscope comprising a camera handle used to fix the camera lens and a wired connector; the camera handle comprises of an outer shell, an end cap and an inner shell; an sensing element is provided inside the inner shell; a lens group is provided between the sensing element and the end cap; the inner shell is fixedly connected with the outer shell through assembling components; the outer shell is fixedly connected with the inner shell through fixing components; a light hole corresponding to the position of the sensing element is cut in the middle of the end cap. The present invention has following advantages: The inner shell is inside the outer shell; both the inner shell and the outer shell are fixedly connected with the end cap; overall sealing, waterproof and dustproof performances of the camera handle are excellent; the removable waterproof cover is provided at the end of the sleeve; the elastic sealing ring is provided between the waterproof cover and the assembling tube; the connector is in a sealed space and protected from being damaged by penetrated disinfectant; with excellent waterproof performance and safe use, the wired connector is suitable for medical equipment.

An exemplary embodiment comprises a laryngoscope comprising a handle; a blade, the blade including a cavity, the cavity housing a lighting system comprising a light source and a battery; and a cover that locks in place over the cavity, wherein the laryngoscope comprises at least one cutout configured to allow an endotracheal tube to pass through.

A relay adapter includes a first connector configured to connect to a processor supplying a first power. The relay adapter includes a second connector configured to connect to an insertion instrument operable using a second power. The relay adapter includes a power circuit coupled to the first connector to receive the first power. The power circuit is configured to convert the first power into the second power The power circuit is coupled to the second connector for delivering the second power to the second connector. The relay adapter includes a switching circuit coupled to the power circuit. When the second connector is not connected to the insertion instrument, the switching circuit prevents the power circuit from delivering the second power to the second connector.

The invention concerns a handle for a video endoscope including a housing and an interface portion rotatably supported relative to the housing where the interface portion includes a first connector element at its distal end section that is connectable to a second connector element of an associated elongate shaft of the video endoscope. Thereby a detachable, rotatable electrical and/or mechanical connection between the handle and the associated shaft is achieved. The coupling includes an electrical connection assembly arranged at an exterior of the interface portion forming an electrical connection to a stationary electric component of the handle. The handle includes a mechanical rotation stop for a rotation of the interface portion relative to the housing such that a rotation range is limited and damage to the electrical connection assembly is prevented.

An aspect of an embodiment of the invention, relates to an imaging capsule for scanning inside a living body with a fail-safe radiation mechanism that prevents the emission of radiation from the imaging capsule until the imaging capsule is instructed to emit radiation and power is available to activate a motor to unblock the emission of radiation. Optionally, when power is not available the imaging capsule automatically, blocks the emission of radiation.

Aspects disclosed in the detailed description include an ingestible power harvesting device and related applications. An ingestible power harvesting device includes a cathode electrode and an anode electrode that can catalyze a power generating reaction to generate a direct current (DC) power when surrounded by an acidic electrolyte. The cathode electrode and the anode electrode are coupled to an encapsulated electronic device that includes power harvesting circuitry configured to harvest the DC power and output a DC supply voltage for a prolonged period. In examples discussed herein, the prolonged period is at least five days. The DC supply voltage powers an electronic circuit in the encapsulated electronic device to support a defined in vivo operation (e.g., controlled drug delivery, in vivo vital signs monitoring, etc.). As such, the ingestible power harvesting device can operate in vivo for the prolonged period without requiring an embedded conventional battery.

A first connector for a medical instrument has one or more first channels extending through a first surface, and terminating at respective ends. A second connector has opposing second channels for coupling with the first channels. A first power transfer element is mounted on the first connector, and defines a first cross-sectional shape that encompasses at least one of the one or more first channels and has a first central axis extending through the first surface. A second power transfer element on the second connector defines a second cross-sectional shape that encompasses at least one of the one or more second channels and has a second central axis extending through the second surface. The first power transfer element may instead be on a side surface of the first connector, and may couple with a paired element on a receptacle or extension of the second connector.
