A visual tooth cleaning, grinding and polishing instrument includes a host, an oral observation instrument and a cleaning and polishing tool. The host can drive the cleaning and polishing tool and supply a power source and a control system for an illuminating system, an observation system and the oral observation instrument. A picture shot by a camera of the observation system can be transmitted to a display of the observation system in time, so as to achieve the purposes of cleaning the teeth while observing a process of cleaning the dental calculus, dental plaque and pigmentation on the surface of the teeth with the cleaning and polishing tool and the cleaning effect instantly on a mobile phone, thereby effectively cleaning, grinding and polishing the teeth. A flusher or an electric toothbrush head or other interdental cleaning tools may also be mounted on the host or the oral observation instrument.

The disclosure relates to a distal endoscope head including a support for a vision system, the support being delimited on one side, by a proximal face and, on the opposite side, by a distal face into which the vision system opens out, the support being traversed by at least one hole of an operating channel opening out into the distal face by an ovoid section which decreases from the distal face of the support in the direction of the proximal face of the support.

A medical system includes a medical device and an end cap. The medical device includes a handle, including an actuation device, and a shaft extending from the handle. A distal end of the shaft includes a tab, and the tab is movable based on movement of the actuation device. The end cap includes a modular camera assembly. The modular camera assembly includes a camera, a support, an arm, and a cavity. The tab is coupleable to the modular camera assembly via the cavity, and movement of the tab controls a position of the support and the camera.

An endoscopic cap assembly may include a sleeve and a cap. The cap may include a cap channel extending along an external surface of the cap. The cap may also include an engagement feature extending radially outwardly from the external surface of the cap.

A minimally invasive surgical instrument including a viewing instrument and a wiper mechanism configured and adapted to clean a lens of the viewing instrument. The wiper mechanism includes a wiper that is configured and adapted to contact and translate across a surface of the lens. An actuator moves the wiper across the lens to clean the lens.

The endoscope includes an imaging device that is provided in a tip portion of an insertion part capable of being inserted into a body cavity. The imaging device includes an image sensor that photoelectrically converts imaging light incident on an image receiving surface thereof through an imaging lens provided in a lens barrel, and a circuit substrate including a connecting surface facing a terminal face that is a surface opposite to the image receiving surface of the image sensor. A plurality of terminals are uniformly arranged longitudinally and laterally in a two-dimensional matrix form on the terminal face of the image sensor, and the connecting surface of the circuit substrate and the terminal face of the image sensor are connected to each other through the plurality of terminals. The total area of the plurality of terminals on the terminal face occupies 10% or more of the area of an imaging area of the image receiving surface.

A cover (1) for a shaft of a medical scoping device comprises tubular member (2) arranged for application on the distal tip of the medical scoping device. The cover (1) comprises a plurality of projecting elements (3) spaced apart circumferentially around the tubular member (2), each projecting element having a base portion (13) and an arm portion. The projecting elements are pivotably mounted on the tubular member about a pivot axis. The base portion (13) comprises a detent (20), and the tubular member comprises a contact region, for example a protuberance (23), said contact region being located such that pivoting movement of the projecting element for moving the arm portion in a distal direction can effect impacting of the detent (20) on the contact region (23).

An endoscope add-on assembly adapted to be attached to a target endoscope. The assembly includes an ultrasound imaging sub-assembly, including a communications cable connected to an ultrasound imaging head and an imaging head movement sub-assembly, including a conduit, holding a tension member that is attached to the ultrasound imaging head. Further included are connective elements, adapted to permit the endoscope add-on assembly to be attached to the target endoscope. Finally, the imaging head movement sub-assembly is detachable from the ultrasound imaging sub-assembly, thereby permitting the imaging head movement subassembly to be processed separately from the ultrasound imaging sub-assembly, after use.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to traction systems, and methods of use thereof, for endoscopic procedures such as tissue dissection. For example, a traction system may include a filament extendable along an outer surface of an endoscope with a distal end of the filament attachable to a medical device engaged with a target tissue of a body lumen.

An endoscope includes a distal end portion main body arranged at a distal end portion of an insertion portion, the distal end portion main body including a recess, the distal end portion main body including at least one screw hole in at least one of a periphery of the recess or an interior of the recess, a lid configured to cover an opening of the recess, the lid including at least one through-hole at a position corresponding to the screw hole, a resin configured to fill a gap between the lid and the distal end portion main body, at least one screw configured to fix the lid to the distal end portion main body, the screw being inserted through the through-hole and screwed into the screw hole, at least one screw cover having an insulation property and configured to cover an upper surface of the screw, the screw cover being disposed closer to a proximal end side than to the recess, and a distal end cover configured to cover a part of the distal end portion main body.
