An optical module for endoscope includes a light emitting element, an optical fiber, a ferrule to which the light emitting element is bonded, a wiring board to which the ferrule is bonded, and a resin disposed between the ferrule and the wiring board, wherein the ferrule has a first principal surface made of a transparent material, a second principal surface, and a side surface, the second principal surface has an opening of an insertion hole, the second principal surface has an opening of a groove communicating with the insertion hole, the side surface has an opening of the groove, and a first distance between the opening of the groove on the side surface and the first principal surface is greater than a second distance between the bottom surface of the insertion hole and the first principal surface.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

A polymeric device including: an elongated hollow tube having an outer surface; and a spiral fin wound around the outer surface of the hollow tube; wherein the hollow tube and the spiral fin are formed of a single unitary piece through a molding process. The polymeric device can further include a longitudinal projection projecting from the outer surface of the hollow tube, the longitudinal projection having a greater thickness than other portions of the hollow tube and the longitudinal projection extending at least a portion of a longitudinal length of the hollow tube.

An endoscope including a bending section, a control device, at least one steering wire, a distal tip part including an exterior housing including a circumferentially extending side wall with a proximal opening, a camera assembly positioned in an interior cavity of the exterior housing, and an interior housing part positioned in the exterior housing, wherein a distal segment of the at least one steering wire is fixed to a wire portion of the interior housing part so that manipulation of the control device causes bending of the bending section.

There is provided herein, an electronic circuit board assembly for a tip section of a multiple viewing elements endoscope, the assembly including a base board configured to carry a first metal frame to support a front looking viewing element and a second metal frame to support a side looking viewing element; and a flexible illumination circuit board comprising a front foldable panel configured to carry three sets of front illuminators for essentially illuminating the field of view (FOV) of the front looking viewing element, and a side foldable panel configured to carry a set of side illuminators for essentially illuminating the field of view (FOV) of the side looking viewing element.

An image pickup device that is provided at a distal end portion of an insertion unit of an endoscope having a longitudinal axis, includes: a first lens barrel that houses a first optical system; a second lens barrel that is disposed on a proximal end side of the first lens barrel, houses a second optical system on which light having passed through the first optical system is to be incident, and includes a second lens barrel-distal end portion that is a distal end portion having a diameter smaller than a diameter of a first lens barrel-proximal end portion which is a proximal end portion of the first lens barrel; a sliding part that is provided around an outer peripheral surface of the second lens barrel-distal end portion and that is in contact with the first lens barrel-proximal end portion; and a pressing member that is externally fitted over the sliding part from the first lens barrel-proximal end portion. The pressing member includes a pressing member-inner peripheral surface that is in contact with both an outer peripheral surface of the first lens barrel-proximal end portion and an outer peripheral surface of the sliding part, and a movement restricting portion that restricts a movement of the sliding part in an axial direction of the longitudinal axis between the first lens barrel-proximal end portion and the movement restricting portion.
