The latching mechanism is configured to cause the platform to be held in the depressed configuration.

An endoscope system is provided, which comprises an endoscope having a hollow tube formed therein, a flexible elongate member having a first end for operational control and a second distal end for operation of robotic members, one or more actuators coupleable to the flexible elongate member at the first end thereof, and an anti-buckling tube arranged with respect to the hollow tube at the first end of the endoscope to prevent buckling of the flexible elongate member during translation of the one or more actuators. Different embodiments are also disclosed, including an endoscope comprising one or more flexible tendons having a wire coil sheath which includes wire having a substantially rectangular cross section, or an endoscope comprising a rotational-motion transmitting device, one or more flexible tendons and one or more electrical wires having anti-kink support thereon, a coupling means constraining the robotic member to an asymmetric range of motion, or torque joint means comprising a centrally aligned pulley for coupling the robotic member.

A master manipulator includes a first master manipulator module, a second master manipulator module, and a third master manipulator module which are perpendicular to each other, an output end of the third master manipulator module is connected to an input end of the second master manipulator module; an output end of the second master manipulator module is connected to an input end of the first master manipulator module; the first master manipulator module can be connected to a main controller. The minimally invasive surgery robot master manipulator is simple and compact in structure, and can realize a high-precision surgical operation; moreover, the master manipulator modules are located above a transverse third master arm, thereby reducing the size of each master manipulator in a vertical direction, and effectively avoiding interference between the master manipulator and other components in the vertical direction.

One exemplary embodiment relates to an input unit (10) for operating a medical instrument (12) with a hollow shaft (14) extending along a longitudinal axis (L) for receiving guide wires (20), with a tool (16) arranged on the distal side of the shaft (14), extending along an extension axis (E) and a control unit (18) arranged proximally on the shaft (14) for handling the tool (16) by means of the guide wires (20), comprising first input means (22) for continuous, pivoting and rotation-true, preferably uninterrupted and/or absolute, conversion of an ergonomically limited user input, in particular a natural user movement of movable first operating means, into an adjustment movement of the tool (16) in a first handling mode, in order to pivot the tool (16) by means of the control unit (18) relative to the longitudinal axis (L) in a limited way and/or to rotate about the extension axis (E) in a limited way.

A computer-assisted surgery system allows a user to control movements of a surgical tool by providing, to a control unit, inputs in the form of measured displacements via a movable part of a handle while treating a region of interest with the tool. The control unit is configured to enable motion of the tool with respect to an anatomical structure only if a user moves the movable part, receive the measured displacement of the movable part, receive from a localization unit the relative position and orientation of the tool relative to the anatomical structure, based on the measured displacement, on the surgical plan and on the relative position and orientation of the tool relative to the anatomical structure, compute an instruction to send to a motorized joint to move a robotic arm to operate the tool according to an optimal trajectory, and send the computed instruction to the motorized joint.

A robotic imaging system includes a camera configured to one or more images of a target site. The camera may be a stereoscopic camera configured to record a left image and a right image for producing at least one stereoscopic image of the target site. A robotic arm is operatively connected to the camera, the robotic arm being adapted to selectively move the camera relative to the target site. A sensor is configured to detect forces and/or torque imparted by a user for moving the stereoscopic camera and transmit sensor data. A controller is configured to receive the sensor data, the controller having a processor and tangible, non-transitory memory on which instructions are recorded. The controller is adapted to selectively execute an assisted drive mode, which includes determining a movement sequence for the robotic arm based in part on the sensor data and a damping function.

A medical system comprising a medical instrument including at least one elongated actuation member used to move at least a portion of the medical instrument, a motor coupled to the medical instrument and used to operate the at least one elongated actuation member, and a control system in communication with the medical instrument and with the motor. The control system is configured to receive at least one input from the medical instrument and determine a force on a tip of the medical instrument by applying the at least one input to a lumped model of the medical instrument. The lumped model comprises a mass of the motor and a spring parameter coupling the mass of the motor to a mass of the portion of the medical instrument.

Disclosed is a console for operating an actuating mechanism, relating to the technical filed of automatic control, and being for use in resolving the technical problem of shift of a controller under the influence of gravity. The console for operating an actuating mechanism includes a controller and a support base. The controller is constrained in both the longitudinal direction and the vertical direction, so that connection between the controller and the support base is tight and reliable, and no displacement would occur in any of three directions (i.e., the longitudinal direction, the horizontal direction, and the vertical direction). Thus, the phenomenon that position information given by the controller is inaccurate due to shift of the controller under the influence of the gravity after long-term usage can be avoided, thereby removing the factors affecting success of surgery, and ensuring the success rate of the surgery.

A robotic surgical intervention device includes an articulated arm, with actuating motors, a distal end of which is intended to carry a surgical instrument, a control peripheral of the articulated arm for moving a functional end of the surgical instrument along a path, and a processor for processing movement instructions provided by the control peripheral to convert them into instructions for controlling the actuating motors of the articulated arm. It further includes a trigger for automatic reversal of the articulated arm, the actuation of which causes individual reverse control instructions to be sent to each of the actuating motors of the articulated arm for a reverse movement of the functional end of the surgical instrument along the completed path.

A robotic surgical intervention device includes an articulated arm with actuating motors, a surgical instrument carried by the articulated arm, a control peripheral of the articulated arm for moving a functional distal end of the surgical instrument, and a processor configured to process movement instructions provided by the control peripheral to convert them into individual control instructions for each of the actuating motors of the articulated arm. The processor includes an electronic restriction designed to add further processing to the movement instructions provided by the control peripheral that blocks any movement of the functional distal end of the surgical instrument according to at least one degree of freedom in translation or rotation predefined as prohibited along or about at least one axis of a local Cartesian coordinate system linked to the surgical instrument.
