A trocar is provided that is adapted to insert a lighting attachment into a body cavity. The trocar connects at its distal end to the lighting attachment such that it can be pushed into the body cavity. An endoscope may then be inserted through the trocar into the body cavity. The lighting attachment is configured to detach from the trocar and attach to the endoscope head to provide additional lighting to the endoscope. The lighting attachment includes foldable lighting panels that expand when in use in order to light a wider field of view. The lighting attachment may be powered by induction coil from the endoscope.

An imaging system aka 3d camera operative in conjunction with a tube having two open ends, the system comprising active portions small enough to fit into the tube and an electronic subsystem including a hardware processor operative to receive image/s from the active portions and to generate therefrom at least one 3D image of a scene visible via one of the tube's open ends. The system may comprise a tracker configured to be secured to the tube, and a method for monitoring location, e.g. absolute location, of the tube, accordingly.

A method, instructions for which are executed from a computer-readable medium, calibrates a robotic camera system having a digital camera connected to an end-effector of a serial robot. The end-effector and camera move within a robot motion coordinate frame (“robot frame”). The method includes acquiring, using the camera, a reference image of a target object on an image plane having an optical coordinate frame, and receiving input signals, including a depth measurement and joint position signals. Separate roll and pitch offsets are determined of a target point within the reference image with respect to the robot frame while moving the robot. Offsets are also determined with respect to x, y, and z axes of the robot frame while moving the robot through another motion sequence. The offsets are stored in a transformation matrix, which is used to control the robot during subsequent operation of the camera system.

The present technology relates to a control device, a control method, and a surgical system that enable an operator to implement operation without a burden. A control unit controls a plurality of patterns of operations of a surgical instrument, and an acquisition unit obtains motion information indicating a motion of a user. Furthermore, the control unit controls the operations of the respective patterns corresponding to the motion information obtained by the acquisition unit in parallel using only a single operation performed by the user as a trigger. The present technology can be applied to a control device of a surgical system.

A stereoscopic imaging apparatus for use in a robotic surgery system is disclosed and includes an elongate sheath having a bore. First and second image sensors are adjacently mounted at the distal end to capture high definition images from different perspective viewpoints for generating three-dimensional image information. The image sensors produce an unprocessed digital data signal representing the captured images. A wired signal line transmits the unprocessed digital data signals along the sheath to a proximal end to processing circuitry. The processing circuitry is configured to perform processing operations on the unprocessed digital data signals to produce respective video signals suitable for transmission to a host system or for driving a 3D display. A secondary camera is also disclosed and includes an elongate strip of circuit substrate sized for insertion through a narrow conduit, the strip of circuit substrate connecting between an image sensor and a processing circuit substrate.

A surgical robot for use in endoscopic surgery includes a control device that implements a position information calculator that calculates information relating to a distal end position of the treatment instrument used in endoscopic surgery, and information relating to a distal end position of an endoscope, a first display section that displays a relative positional relationship between the distal end of the treatment instrument and the distal end of the endoscope by using a calculation result obtained from the position information calculator, and a second display section that displays an image captured by the endoscope.

A surgical robot for use in endoscopic surgery includes an arm device that holds a surgical instrument used in endoscopic surgery, a drive device that drives the arm device, a display section, and a display processor that displays, on the display section, a relative positional relationship between a trocar site and a distal end position of the surgical instrument.
