An endoscope control system for performing a bending operation in a disposable insertion endoscope, the endoscope control system including a control wheel connected to a wire drum for connection to a steering wire of the endoscope, whereby rotation of the control wheel controls the bending operation, and a multi-disc brake including a stack of at least three brake discs, wherein activation of the multi-disc brake changes the multi-disc brake from a released state to a braking state, a brake torque generated by the multi-disc brake in the braking state braking rotation of the control wheel, the brake torque in the released state being at least partially released.

A handheld, steerable catheter robotic system includes a catheter having a flexible outer sheath, at least one flexible multi-lumen assembly and a robotic instrument for performing a surgical procedure. The catheter is removably insertable into an instrument channel of an endoscope. The flexible multi-lumen assembly extends through the outer sheath. The robotic instrument is operatively and removably attachable to a distal end of the multi-lumen assembly such that the robotic instrument is teleoperable. The catheter robotic system also includes a handle operatively and removably attachable to a proximal end of the catheter. The handle is configured for hand-held operation and includes a joystick for steering the robotic instrument.

Endoscopes comprising a reusable hand-piece and separable disposable shaft assembly are illustrated and described. The reusable hand-piece includes a housing having an articulation control mounted thereto and an electronics module mounted thereto. The articulation control includes control knobs and concentric drive shafts for articulation. The electronics module includes a battery, a control board, and an optical and/or electrical connector. The separable disposable shaft comprises a housing having an articulation wire actuating assembly mounted thereto and an optical and/or electrical connector mounted thereto. When the housing of the hand-piece and the housing of the separable disposable shaft assembly are joined together, the articulation control engages the articulation wire actuating assembly and the optical and/or electrical connector of the reusable hand-piece engages the optical and/or electrical connector of the disposable shaft assembly.

A medical device is configured such that a distal end of an operation wire is securely fixed to a distal end of a shaft, enabling smooth distal end deflection operation. The medical device includes: a shaft that includes a distal end flexible portion and in which working lumens and wire lumens are formed; a distal end tip disposed on a distal end side of the shaft and in which distal end working lumens in communication with the working lumens are formed; an intermediate member disposed between the shaft and the distal end tip and including a main through-hole that is formed to secure communication paths with the working lumens and the distal end working lumens and surround the communication paths, and sub-through-holes that are formed to correspond to the positions in which the wire lumens are formed.

A motor-driven endoscope includes: an insertion unit which is configured so that at least a part from one side thereof, and which includes a curve unit that is configured to be bent when being pulled by a wire inserted therein; a grip unit which is provided at one side of the insertion unit and is held by a user to input a driving input; a plurality of motors for transferring driving power so as to steer the curve unit; and a tension adjustment unit which is provided at the other side of the insertion unit and receives a rotating force from the motors to pull each wire, wherein the tension adjustment unit and the motor are configured to be coupled to or uncoupled from each other, and the tension adjustment unit is configured to receive the rotating force from the motor when coupled to the motor.

A steering assembly of a medical device may comprise a handle having a recess and first and second wire guides disposed within the recess. At least one of the first or second wire guides may be keyed to the recess to prevent rotation of the first or second wire guide within the recess. First and second wire segments may be configured to steer a sheath coupled to the steering assembly in first and second directions. The first wire segment may pass through a first gap between the first wire guide and the second wire guide. The second wire segment may pass through a second gap between the first wire guide and the second wire guide. Neither of the first nor the second gap may occupy any overlapping space.

An endoscope and a method of assembling the endoscope, the endoscope including a handle including a wire receiving unit rotatably connected to an operating unit; a distal tip unit configured to be inserted into a patient’s body cavity; -an endoscope shaft connecting the endoscope handle and the distal tip unit; and at least one steering wire, a proximal end portion of which being held by or fixed to the wire receiving unit, the steering wire being configured to be pulled by rotating the operating unit, thereby tilting the distal tip unit in at least a defined first direction, wherein the proximal end portion of the at least one steering wire is wound around/on the wire receiving unit for at least one full turn.

Arrangements comprising an endoscope system having an endoscope including a reusable hand-piece, a separable single-use shaft assembly, a single-use cartridge and a console are disclosed. Endoscope assemblies having articulation knobs attached by friction fit, multi-stage rotational distance limiters, and/or elevators are disclosed. Components of same, packaging systems, and methods are also provided.

Endoscope assemblies, systems, and methods of manufacturing same are disclosed. In particular, endoscopes having controls and/or tool port openings one end of an elongate handle and the insertion tube assembly and umbilical extending to the console at another end of the elongate handle are provided. Fluid control and flow path arrangements in the handle of the endoscope are also described as well as configurations for articulation links and constructions for insertion tubes.

A bending piece of a medical device includes: a ring-shaped piece main body having a peripheral wall part whose cross-section orthogonal to an axial direction is formed in a C-like shape and a slit-shaped opening part extending in the axial direction and provided between one end and the other end of the peripheral wall part in a peripheral direction; a first extension body extending from the peripheral wall part to one side in the axial direction; a second extension body extending from the peripheral wall part to the other side in the axial direction; a connecting shaft provided on the first extension body so as to extend outward in a radial direction orthogonal to the axial direction; and a connecting hole formed in a direction parallel to the connecting shaft, having a shape corresponding to an outer shape of the connecting shaft, and provided in the second extension body.
