An articulating medical device with a handle and an articulating elongate member extending from the handle. The handle has a cavity with at least one first rotatable member. The first rotatable member has a first lever arm and a first termination coupling. Coupled to the termination coupling is at least one first articulation cable. The first lever arm is arranged to limit displacement of slack in the at least one first articulation cable when the at least one first articulation cable is not under tension.

A multi-channel endoscope can include a control section and an insertion end. The endoscope can include a user control mechanism. The control section can include at least one working channel and a channel within the control section. The working channel can accommodate at least one medical instrument which can fracture a target object into fragments. A catheter, such as a fluidic catheter, can extend from and retract to an originating proximal position at the insertion end of the endoscope. A vacuum pressure source or an irrigation source can be coupled to a proximal end of the channel. The user control mechanism can control the position of the catheter with respect to the endoscope and can be used to operate the vacuum pressure source or irrigation source.

An endoscope system includes: an endoscope including a bending portion that is capable of bending; a drive device that is detachably connected to the endoscope and drives the endoscope; and an operation device that is communicably connected to the drive device and has an input portion that inputs an operation for driving the endoscope, wherein the drive device can select a method of controlling the bending portion with respect to the operation input from the input portion from fine movement control and coarse movement control, and the distance at which the drive device bends the bending portion by the coarse movement control with respect to a predetermined operation input is larger than the distance at which the drive device bends the bending portion by the fine movement control.

A medical endoscope that has a reusable portion to which either of two different single-use portions can be snapped in by hand to thereby form two different assembled endoscopes. When one of the single-use portions is assembled with the reusable portion, a motor in the reusable portion robotically rotates a cannula about a proximal end of the single use portion. When the other single-use portion is assembled with the reusable portion, the motor robotically angulates the distal end of the cannula. Another medical endoscope is single-use in its entirety and has motor-driven angulation of the cannula's distal end. Another has manually controlled angulation.

An endoscope comprising: an insertion portion; a raising base provided at a distal end of the insertion portion; a wire configured to move in a raising direction to raise the raising base; a biasing element attached to the wire and configured to apply to the wire a biasing force in the raising direction; and an operation portion coupled to a proximal end of the insertion portion, the operation portion including a switching mechanism having a first state and a second state. The switching mechanism is configured to switch between the first state and the second state. In the first state, the switching mechanism prevents the biasing force from moving the wire in the raising direction and, in the second state, the switching mechanism allows the biasing force to move the wire in the raising direction.

A laryngoscope blade (30) includes a blade proximal end (32), to be articulated to a handle (20), a blade distal end (38), a patient tongue side (34), a patient palate side (36), a plurality of adjacent rigid elements (40, 50, 60, 70) extending from the tongue side to the palate side, a plurality of joints (46, 56, 66) articulately connecting two of the adjacent rigid elements, and a force-transmitting mechanism (80), with a proximal end (82) and a distal end (87). The force-transmitting mechanism distal end is mechanically connected to the blade distal end. The force-transmitting mechanism is movable relative to the rigid elements in a longitudinal direction. The force-transmitting mechanism proximal end is mechanically couplable to the handle such that, by pivoting of the handle relative to the blade proximal end, the force-transmitting mechanism is moved relative to the blade proximal end.

An endoscope includes an insertion portion provided with a controllable curved tube. The controllable curved tube includes a plurality of circular tube sections connected in series. A first C-shaped engaging portion is arranged at one end of each tube section. A first included angle is formed between the opening direction of the first C-shaped engaging portion and the axial direction of the tube section to which the first C-shaped engaging portion belongs. A first C-shaped notch is arranged around the outside of the first C-shaped engaging portion. The other end of the tube section is provided with a second C-shaped engaging portion that is engaged with the first C-shaped notch of another tube section. The inner side of the second C-shaped engaging portion is provided with a second C-shaped notch and a spherical protrusion which are engaged with a first C-shaped engaging portion of another tube section.

An external mechanism for an endoscope includes: a bending wheel configured to engage with a second UD knob of a second bending operation device provided in an operation portion of an endoscope; a motor portion configured to generate a driving force for rotating the bending wheel; a housing case housing the bending wheel and the motor portion and detachably attached to the operation portion, and an operation switch arranged outside the housing case and configured to output a control signal to the motor portion due to the operating element being operated, in which the operation switch is pivotally supported by the rotation shaft and rotates with respect to the housing case.

In some embodiments, an insertion device for a single port robotic surgery apparatus includes a plurality of instrument channels positioned in an interior of a housing and extending along substantially an entire length of the housing, the plurality of instrument channels configured to removably house a plurality of surgical instruments, a plurality of openings in a rear exterior surface of the housing, the plurality of openings providing access to the plurality of instrument channels and configured to facilitate insertion of the plurality of surgical instruments into the plurality of instrument channels, and an illumination device supported at least partially at the rear exterior surface of the housing and positioned proximal to the plurality of openings, the illumination device configured to illuminate the openings to facilitate insertion of the plurality of instruments through the plurality of openings.

A method for fixing a guide sheath of a cable for actuating the distal head of a medical device including providing a housing having at least one column made of a thermoplastic material for fixing a support sheath, arranging, from the terminal portion of the column, a groove that extends radially therethrough to allow the insertion of the support sheath, positioning the support sheath of the actuating cable inside the groove while a free end extends out of the column, and heating at least the free end of the column and applying a pressure to the column to ensure the attachment of the support sheath to the housing by means of welding.
