A manipulator system includes: a manipulator including an elongated flexible section, a movable section provided at a distal end of the flexible section, and a driver that is provided at a proximal end of the flexible section and that drives the movable section; an insertion section having a channel into which the manipulator is inserted; an advancing/retreating section that advances/retreats the manipulator and that causes the movable section of the manipulator to protrude from, and to be withdrawn into, a distal end of the channel; a protrusion-state acknowledgement section that acknowledges a protrusion state in which an entirety of the movable section protrudes from the distal end of the channel; and a restricting section that, when the protrusion state is acknowledged with the protrusion-state acknowledgement section, restricts further retreating motion of the driver performed by the advancing/retreating section.

An endoscope with more flexibility, higher curvature and longer service life, for increasing the convenience of an endoscopic procedure. The endoscope includes a flexible bending section with slits of various width at different parts, which facilitates high dimensional bending of the bending section with the assistance of guide wires, while the wider slits at proximal and distal tips offer higher dimensional bending. Unique shape and structure of the slits relieve bending and twisting stress normally exerted on a spot to a surface, which avoids easy wreckage and thus guarantees a longer service life. Besides, the guide wires fastened through buckles ensure more stability and save all the inconvenience from dispensing glue.

A bending portion includes: a bending piece group including a plurality of first bending pieces; and a second bending piece including coupling protruding portions for coupling to a coupling frame so as to resist torsion about the longitudinal axis, and including, on a proximal end side, third contact surfaces facing a direction of the longitudinal axis, the second bending piece including inside a second insertion portion for allowing insertion of internal components, the second insertion portion being formed so as to be coincident with the first insertion portion provided in each of the first bending pieces on a same projection plane, the second bending piece being interposed between the coupling frame and the bending piece group such that the third contact surfaces and a distal-most position of the bending piece group are in rotatably contact with each other.

According to embodiments, a substantially coaxial arrangement of a camera, a light source, and an ultrasonic sensor can be positioned in an housing of a system that can be deployed from the tool port of a standard bronchoscope. Illumination from the light source facilitates positioning of the system by an operator using information from the camera. The ultrasonic system can determine when an object to be biopsied is adjacent to a biopsy needle.

An endoscope made by a method for fixation of portions of steering wire of the endoscope, the steering wire having a first portion, a second portion, and a third portion, the method including positioning the second wire portion and the third wire portion of the steering wire adjacent to each other, applying an adhesive, at least partly enclosing the second wire portion, the third wire portion, and the adhesive with a crimp shell, and crimping the crimp shell, the second wire portion, and the third wire portion to thereby fixate the second wire portion in relation to the third wire portion.

The disclosure provides for an endoscopic device and method for manipulating the endoscopic device. The endoscopic device includes a tube assembly and a slider mechanism connected to the cylindrical body for control of the endoscopic device. The tube assembly has a cylindrical body with a proximal end and a distal end and a plurality of openings extending from the proximal end to the distal end of the cylindrical body. The slider mechanism includes a tip deflecting mechanism and a rotation assembly having a planetary gear system.

An endoscope capable of performing a retroflexion manoeuvre, including a handle having a control mechanism, a distal tip part having a vision device with a field of view, a bending section having a first state, a retroflexion state, an insertion tube including an exterior surface facing the surroundings of the endoscope, and at least one steering wire connecting the control mechanism with the bending section so that manipulation of the control mechanism causes the endoscope to perform a retroflexion manoeuvre by bending the bending section from the first state to the retroflexion state, wherein the exterior surface of the insertion tube includes a coloured area of a colour configured to reduce over- or underexposure of the vision device in the retroflexion state.

An endoscope including a handle including a fulcrum with a fulcrum axis, and a control lever including a lever body attached to the fulcrum and rotatable about the fulcrum axis, a lever grip, and a lever arm attaching the lever grip to the lever body, the control lever being adjustable between a first and a second configuration, in which the gripping surface of the lever grip is distanced from the fulcrum axis at a first radial distance via the lever body and lever arm, and a second configuration, in which the gripping surface of the lever grip is distanced from the fulcrum axis at a second radial distance via the lever body and lever arm, wherein the second radial distance is different from the first radial distance.

A medical device comprising a shaft defining a first channel having a distal opening, a printed circuit board (PCB) coupled to a distal end of the shaft to expose the distal opening to an external environment, wherein the PCB includes an imager and at least one light, the imager and the at least one light mounted on a distal facing surface of the PCB, and an optically clear covering, wherein the covering covers the imager and the at least one light.

An endoscope apparatus includes a bending portion bent by at least one bending wire, the bending portion including a first region and a second region in a longitudinal direction of the bending portion, the second region being a region provided on a proximal end side of the first region and configured to be bent following bending of the first region, the at least one bending wire being held on a proximal end side of the second region, the first region and the second region being integrally formed.
