A control apparatus controls an operation of a self-propelled mechanism of an endoscope. The control apparatus includes a drive circuit that outputs a motor current, a motor current detection circuit that acquires a value relating to magnitude of the motor current as a detection value, a storage circuit that stores a limit value relating to the detection value, and a control circuit that performs an operation as a first controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds a value relating to the limit value, and performs an operation as a second controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds the value relating to the limit value.

A surgical system according to one or more embodiments may include: manipulators respectively supporting an endoscope and first and second surgical instruments; a remote control apparatus including a display device, a first operation handle for right hand to operate the first surgical instrument, and a second operation handle for left hand to operate the second surgical instrument; and a control apparatus. The control apparatus may display, on the display device, a graphical user interface, overlapped with the image captured by the endoscope, the graphical user interface including a first area that displays information on the first surgical instrument to be operated by the first operation handle, a second area that displays information on the second surgical instrument to be operated by the second operation handle, and a third area that displays information on the endoscope, which are arranged side by side in order from right to left.

An endoscope according to an embodiment includes an elongated insertion section including a bending section configured to bend in at least an up-down direction by internally-disposed two or more wires being towed, an operation section including a grasping section, the operation section, a bending operation unit including a joystick for bending the bending section and provided in the operation section, two actuators respectively including turning shafts, the two turning shafts being internally disposed in the grasping section in a longitudinal direction of the grasping section, the two actuators being disposed side by side along a plane parallel to an operation direction of an operation member for bending the bending section in the up-down direction, and a conversion mechanism including a rotation torque transmission mechanism and a tensile force transmission mechanism, the conversion mechanism converting the rotation torque into the tensile force.

Endoscopic viewing systems for use in diagnostic and therapeutic medical procedures. More specifically, an imaging and control system and coupler that allows for control of imaging and fluid management from a hand-held unit coupled to a conventional multiple-use, sterilizable endoscope.

A surgical imaging system including a surgical imaging device including identification information; a holding arm that holds and controls a position of the imaging device; a user interface configured to provide non-contact operation of the holding arm; and processing circuitry configured to control the holding arm according to the identification information and an output of the user interface.

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 method and system for foot-actuated device to switch between a vacuum supply and an oxygen supply in a medical environment. The system enables a user to press down on the device to compress a first tube and open a second tube. When the user releases the device, the first tube is opened and the second tube is compressed.

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.

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.

An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.
