An endoscope includes a channel tube provided in a direction of a longitudinal axis of an insertion section, and a pipe sleeve provided in the operation section and including a tube insertion hole on a distal end side, the proximal end side of the channel tube being inserted in the tube insertion hole. An inner diameter at a first position on a proximal end side of the pipe sleeve is larger than an inner diameter at a second position in a hole part that communicates with a proximal end of the tube insertion hole, the inner diameter at the second position of the pipe sleeve is smaller than an inner diameter at a third position in the tube insertion hole, and the pipe sleeve includes an abutting surface at the proximal end of the tube insertion hole.

An apparatus comprises a video baton for insertion into a plurality of laryngoscope blade covers having different sizes and geometries. The video baton comprises: a handle portion, a shuttle assembly slidingly positioned within the handle portion between an extended position and a retracted position, and a flexible coupling element having a proximal end and a distal end. The flexible coupling element is coupled to the shuttle assembly at the proximal end and an image capturing and lighting assembly positioned at the distal end of the flexible coupling element.

For determining a precise orientation and positioning of an endoscope in an electromagnetic field, an endoscope device has a proximal insertion head and has a shaft extending distally therefrom having a center axis. The shaft extends with at least one elongated lumen through the device. A sensor rod has at least two sensor coils arranged with finite spacing in relation to one another in the longitudinal direction. The at least two sensor coils are oriented in relation to one another at a finite angle.

A detachable endoscope includes an insertion unit including an illuminating and image pickup unit, an operation unit configured to bendingly operate a front end of the insertion unit, and a detachable unit configured to detachably couple the insertion unit and the operation unit to each other, wherein the detachable unit includes: a first detachable module disposed at the insertion unit; and a second detachable module disposed at the operation unit, wherein the first detachable module includes: a first module main body disposed within a rear end of the insertion unit and having first, second, third and fourth rectilinear guide through-bores penetratingly formed longitudinally therein, and a central opening penetratingly formed at a center of the main body in a thickness direction of the main body.

An endoscope apparatus includes: an endoscope including a first operation portion that is coupled to a first insertion portion to be inserted into a subject; a medical device including a second operation portion that is coupled to a second insertion portion to be inserted into the subject through the first insertion portion, the second operation portion including at least one locking member; and a belt-like body having flexibility and including at least three end portions in which at least one end portion includes a locked portion to be locked to the locking portion, the belt-like body being configured to be wound around the endoscope to hold and fix the second operation portion of the medical device in a state where the at least three end portions are connected to the second operation portion.

One of two connector receiving parts of a processor for endoscope has a shutter mechanism configured to open a shutter by an external force, the shutter having a gap through which a connector-side connection end section passes, and being configured to partition a recessed space of the connector receiving part with respect to an outside. In addition, the processor for endoscope includes a lock mechanism configured to make the shutter into the locked state during a period when another connection end section on the connector side and a processor-side connection end section are connected, and release the locked state of the shutter when the connection between the other connection end section on the connector side and the processor-side connection end section is released.

A medical device includes an endoscope head which is designed to be detachably connected to endoscope tubes. The endoscope head has a longitudinal channel between a proximal end and a distal end of the endoscope head for receiving an endoscope tube. At least one measuring channel is arranged in the endoscope head. The measuring channel has at least one inner connection opening, which is connected to the longitudinal channel, and at least one outer connection opening, which is arranged on the outside of the endoscope head. The outer connection opening can be connected to at least one measuring channel in a measurement adapter which can be detachably coupled to the endoscope head.

A dental mirror structure contains a body and a connector. The body includes an inspector, a connection segment, and a first air conduit. The inspector includes a lens, and the first air conduit has an inlet and an outlet adjacent to the lens. The connector is hollow and columnar, and the connector includes a second air conduit defined on a center thereof, a connection portion extending from a first end of the connector, a first stem extending from the connection portion, a second stem extending from a second end of the connector, and a fixing extension extending from the second end of the connector and surrounding the second stem. Thereby, the first stem is connected with an air supply element, the second stem is fitted with the inlet the body, and the fixing extension is connected with the connection segment.

A camera head includes a mounting unit detachably connected to an eyepiece unit of an endoscope, the camera head capturing an object image emitted from the eyepiece unit. The eyepiece unit includes an abutting surface that is orthogonal to a central axis along an insertion direction of the endoscope into a subject, and the abutting surface extending over an entire circumference in a circumferential direction around the central axis. The mounting unit is connected to the eyepiece unit and is configured to relatively rotate the endoscope and the camera head around the central axis. The mounting unit includes a facing surface that faces the abutting surface, and a pressing portion that abuts the eyepiece unit and presses the eyepiece unit toward the facing surface along the central axis. The facing surface includes a projecting portion that projects toward the abutting surface and abuts the abutting surface.

Dental periscopes having mounting clips configured to couple to mobile devices are disclosed. A patient can mount the dental periscope to a mobile device by coupling the mounting clip of the periscope to the mobile device. The patient can then use the mobile device-mounted dental periscope to capture image and/or video data of one or more dental structures. The captured image/video data can be sent to a remote system to obtain a remote dental diagnosis based on the captured data. The remote diagnosis may be an automated diagnosis generated by a trained machine learning classifier.
