Provided is an endoscope capable of suppressing the displacement of a movable optical frame due to bending of a bending portion. An endoscope according this embodiment includes an insertion portion that includes a distal end portion, a bending portion, and a soft portion in order from the distal end side, a movable optical frame (37) that is built in the distal end portion and capable of advancing and retreating in an axial length direction of the insertion portion, an operation coil (13) that is connected to the movable optical frame (37) and capable of advancing and retreating in the axial length direction of the insertion portion, and a protection coil (44) through which the operation coil (13) is inserted and which penetrates at least the bending portion.

An optical system including: a distal optical assembly; a proximal optical assembly; and an image sensor; wherein the distal and proximal optical assemblies define a beam path; the distal optical assembly couples incident beams of light from a field of view located in an object space in the proximal optical assembly; the proximal optical assembly directs the incident beams of light onto a light-sensitive surface of the image sensor; and at least one of the distal and proximal optical assemblies comprise, at least one prism arranged in the beam path, such that the at least one prism limits the field of view of the optical system on at least one side.

An endoscope camera head 6 includes a first and a second members 8, 9 that are relatively rotatable about a first axis Ax1. The first member 8 has a first rotation-sliding surface 84 that extends in an annular shape about the first axis Ax1 as its center. The second member 9 has a second rotation-sliding surface 93 that engages with the first rotation-sliding surface 84 in a state in which movement to a direction of the first axis Ax1 relative to the first member 8 is restricted, and that rotation-slides relative to the first rotation-sliding surface 84 about the first axis Ax1. The second rotation-sliding surface 93 abuts only on a part of the first rotation-sliding surface 84, to expose a part of the first rotation-sliding surface 84 outside.

A medical stapler includes a grasping portion connected to an endoscope and having a first jaw and a second jaw connected by a rotation shaft; an operation portion configured to receive an external force for operating the grasping portion to open and close; a first wire configured to transmit the external force that is received by the operation portion to the grasping portion; and a movable pin attached to a distal end of the first wire, wherein the grasping portion is transitioned to an open state and a closed state by the first/second jaw relatively rotating with each other, and the movable pin is advanceable and retractable between positions at the proximal-end and distal-end side of the rotation shaft in a state in which the movable pin is engaged with an engagement groove formed in the first jaw.

An optical unit for endoscope includes: a moving barrel which is a soft magnetic body, configured to hold a lens; a fixed barrel which is a non-magnetic body, configured to movably hold the moving barrel on an inner circumferential face; a pair of yokes arranged on an outer face of the fixed barrel; a coil wound around the outer face of the fixed barrel and a magnet arranged on a part in the circumferential direction, between the pair of yokes; and a magnetic body member with magnetism stronger than magnetism of the moving barrel, the magnetic body member being arranged on a part of the moving barrel in the circumferential direction, corresponding to the magnet.

Disclosed embodiments integrate a camera into an intraoral mirror. Integrating a camera into an intraoral mirror provides an efficient way to record and display what is visible to the healthcare provider in the mirror.

A system for modularly assembling a scope device includes an optical module which has an optical housing and a longitudinal member extending distally therefrom. A distal end of the member includes a camera for visualizing a target area, electric wires and a light source extending from the camera to the optical housing. The system also includes a deflector module coupleable with the optical module. The deflector module includes a deflector housing and a deflector shaft extending distally therefrom. The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

An imaging apparatus for endoscope includes: a coupler configured to hold an endoscope for capturing an image of a subject, and emit the image of the subject; an imaging apparatus main body connected to the coupler so as to be relatively rotatable with respect to the coupler around an optical axis of the endoscope, the imaging apparatus main body being configured to capture the image of the subject emitted from the endoscope; and a posture keeping member configured to maintain a posture of the imaging apparatus main body with respect to the optical axis of the endoscope by generating a desired physical quantity between the coupler and the imaging apparatus main body.

A portable endoscopic inspection system comprises an endoscope having a proximal end with a flanged eyepiece for observation and a distal end with a lens assembly for insertion into a region of interest. A light port transports incident light to the region of interest along an lighting pathway, and reflected light is transported along an imaging pathway from the lens assembly to the eyepiece. A wireless imaging unit comprises a light source which detachably couples to the light port for generating the incident light, and an imaging sensor for recording images of the reflected light from the eyepiece. The wireless imaging unit comprises a variable coupling system which mechanically couples the imaging sensor to the flanged eyepiece independent of the shape and/or size of the flange of the eyepiece.
