The present invention relates to the field of medical endoscope, it discloses front-end structure for insertion part of endoscope, which consists of a probe shell a camera, a module arranged on the end surface of the probe shell to observe images of surrounding tissues; an operation hole arranged on the end surface of the probe shell and on the side of the camera module to fix the operation mechanism; the camera module consists of a lens unit and lighting units arranged on both sides of the lens unit, an arc transition surface is arranged on one side of the end surface of the probe shell to guide the probe to be inserted into the targeted tissue. The beneficial effects of the present invention are: a cut angle is arranged on the end surface of one end of the probe shell, when the probe is inserted into the human body, the inclined arc transition surface can reduce the resistance from the human body tissues, so that the probe can be inserted into the human body deeply in an easier manner; by arranging the probe shell and sealing the lighting units with sealant, the probe shell plays a role of positioning and protecting the ends of the lighting units.

An endoscope includes a handle assembly, an elongate shaft extending distally from the handle assembly, a tip disposed at a distal end of the elongate shaft, an imaging device disposed within the tip, and a rotation assembly operably coupled to the imaging device for rotating the imaging device within the tip.

An imaging element according to the present disclosure includes: a photoelectric conversion unit that is configured of a first electrode 21 and a photoelectric conversion layer 23A and a second electrode 22 including an organic material being laminated, an inorganic oxide semiconductor material layer 23B is formed between the first electrode 21 and the photoelectric conversion layer 23A, and an inorganic oxide semiconductor material configuring the inorganic oxide semiconductor material layer 23B contains gallium (Ga) atoms, tin (Sn) atoms, zinc (Zn) atoms, and oxygen (O) atoms.

An endoscope includes a handle operation unit. The handle operation unit includes: an outer ring; a cam ring accommodated in the outer ring to rotate in accordance with rotation of the outer ring about a central axis and having a pair of guide holes; a pair of slide members accommodated in the respective guide holes and fixed to a force transmission member; and a support portion having a pair of slide grooves extending along a longitudinal direction of the endoscope, the support portion being accommodated in the cam ring to support the pair of slide members. The slide members slide in the respective slide grooves in accordance with the rotation of the outer ring. The field of view of the image-capturing unit is changed in accordance with sliding of the pair of slide members.

A stereoscopic imaging apparatus for use in a robotic surgery system is disclosed and includes an elongate sheath having a bore. First and second image sensors are adjacently mounted at the distal end to capture high definition images from different perspective viewpoints for generating three-dimensional image information. The image sensors produce an unprocessed digital data signal representing the captured images. A wired signal line transmits the unprocessed digital data signals along the sheath to a proximal end to processing circuitry. The processing circuitry is configured to perform processing operations on the unprocessed digital data signals to produce respective video signals suitable for transmission to a host system or for driving a 3D display. A secondary camera is also disclosed and includes an elongate strip of circuit substrate sized for insertion through a narrow conduit, the strip of circuit substrate connecting between an image sensor and a processing circuit substrate.

Image rotation in an endoscopic hyperspectral, fluorescence, and/or laser mapping imaging system is described. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a rotation sensor for detecting an angle of rotation of a lumen relative to a handpiece of an endoscope. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of a hyperspectral emission, a fluorescence emission, and/or a laser mapping pattern.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

An optical prism is designed to displace a field of view offset angle of an endoscope. A connector is designed to affix the optical prism to a tip of an endoscope that has a field of view at an initial offset angle displaced off-axis. The optical prism and connector are designed to reduce the offset angle of the field of view of the endoscope toward on-axis. Delivery packaging for an endoscope has a vial, well, or cavity designed to retain anti-adhesive lubricant in contact with a lens or window of the endoscope.

An imaging module includes: an electrical cable; an imaging device; and a flexible wiring board with wirings electrically connecting the imaging device with the electrical cable. The flexible wiring board includes: a device mounting portion on which the imaging device is mounted, and one end of the device mounting portion in a longitudinal direction has a bent portion; and a rear portion that bends and extends from the bent portion to a side opposite the imaging device. The device mounting portion has a mounting surface intersecting an axial direction of a distal end of the electrical cable, and the imaging device is mounted on the mounting surface, and the wirings extend from the mounting surface, pass through the bent portion, and connect with the electrical cable at the rear portion.

The present invention relates to an endoscope including an object, which is to be supplied with electric current, in an endoscope head of the endoscope, and a circuit board for the object to be supplied with electric current. The circuit board extends from the object, which is to be supplied with electric current, in the distal direction of the endoscope head.
