A surgery system includes: an imager capturing an image of a treatment target; a display having a screen displaying the image of the treatment target captured by the imager; and a processor configured to control a display area of the treatment target on the screen, wherein the processor is configure to: calculate a position of a resection end section of the treatment target on the basis of the image of the treatment target acquired by the imager; cause the display area of the treatment target to be moved to a position at which the resection end section is disposed at a prescribed reference position on the screen; calculate an orientation of a marking added to the treatment target on the screen; and cause the display area of the treatment target to be rotated to an orientation in which the marking is disposed in a prescribed reference orientation on the screen.

A holding device is a holding device that holds the medical device, and includes an arm configured to have a holder, which holds the medical device, at a distal end, a base configured to rotatably support the arm by a first joint, a disk attached to the arm, and a brake attached to the base and configured to press the disk, in which a distance between a center of rotation of the disk and a region where the brake presses the disk is changed depending on a rotation angle of the first joint.

Holding device

A joint ring includes a main body part and a pair of protrusion parts protruding from a first surface of the main body part in a direction of a central axis thereof and having spherical surfaces on protruding portions. The main body part includes a pair of engagement holes and a pair of receiving holes. The protrusion parts include engagement parts which are configured to be capable of being inserted into the engagement holes. When the joint rings are arranged in the direction of the central axis and the protrusion parts of a first joint ring enter the receiving holes of a second joint ring, the spherical surfaces come into contact with receiving surfaces inside the receiving holes, and the first joint ring and the second joint ring become rotatable relative to each other with a line segment connecting centers of the respective spherical surfaces as a rotational center.

Joint ring and medical manipulator

A medical manipulator including an insertion portion, where the insertion section including a bending portion and an end effector disposed on a distal end side of the insertion portion. The medical manipulator further including an actuator configured to generate a first drive force for moving the bending portion; a lever configured to generate a second drive force for moving the bending portion, the lever being used to move the bending portion instead of the actuator; a wire configured to transmit the first drive force or the second drive force to the bending portion; and a transmission blocking device configured to switch from the first drive force to the second drive force.

Medical manipulator

A medical device holding apparatus having a first arm with a holding portion to hold a medical device; a second arm connected to the rotatable first arm; a base connected to the rotatable second arm and having a support shaft standing in a vertical direction; and a first counterweight portion connected to the second arm, wherein the second arm has a fulcrum around which the second arm is rotatable, and the first counterweight has a slit being connected to the proximal end portion of the second arm for guiding the proximal end portion of the second arm when the second arm is rotated around the fulcrum; and a guide for moving the first counterweight in the vertical direction after the guide receives a force generated when the proximal end portion of the second arm is guided and moved in the slit.

Medical device holding apparatus

A medical system including a manipulator having a longitudinal portion with a proximal end and a distal end; a rotation driving unit connected to the longitudinal portion for rotating the proximal end; an uneven portion disposed on an outer circumference surface in the vicinity of the distal end and being along a helix; a bendable portion disposed at the distal end; a bending driving unit bending the bendable portion; a shape sensor unit detecting a bending amount and a bending direction of the bendable portion; a rotation angle sensor unit detecting a rotation angle and a rotation direction of the longitudinal portion; and a control unit controlling operations of the rotation driving unit and the bending driving unit, wherein the distal end and the uneven portion are rotatable about the longitudinal axis following the rotation of the proximal end when the proximal end is rotated by the rotation driving unit.

Manipulator, medical system, and medical system control method

A medical manipulator including an insertion portion, where the insertion section including a bending portion and an end effector disposed on a distal end side of the insertion portion. The medical manipulator further including a motor configured to generate a first drive force for moving the bending portion; a lever configured to generate a second drive force for moving the bending portion, the lever being used to move the bending portion instead of the motor; a wire configured to transmit the first drive force or the second drive force to the bending portion; and a transmission blocking device configured to switch from the first drive force to the second drive force.

The traction balance adjustment mechanismincludes a movable partthat goes into operation through at least one degree of freedom, wiresconnected to the movable part, and a traction partthat pulls one of the wiresand pushes out the other, wherein the length of the one wirepulled by the traction partis longer than the length of the other wirepushed out.

Traction balance adjustment mechanism, manipulator and manipulator system

A trocar including a distal-end tube portion that is disposed inside the body and has a first inner hole through which a medical device can be inserted; a proximal-end tube portion that is disposed outside the body and is connected to the distal-end tube portion, the proximal-end tube portion having a second inner hole that communicates with the first inner hole and has an axis which can be disposed in a direction not parallel to an axis of the first inner hole; and a movement facilitating portion that is disposed on at least one of the inner surface of the first inner hole and the inner surface of the second inner hole to facilitate the movement of the medical device inside the inner hole.

Trocar

An image recording apparatus is provided with the following a conveying section including a platen which conveys a recording medium, an image recording section which performs image recording with respect to the recording medium conveyed by the conveying section, and a moving mechanism which moves at least one of the image recording section and the conveying section and enables a movement between a recording position in which the image recording is performed and a non-recording position in which the image recording is not performed, and a positioning section which permits the space between the image recording section and the conveying section to have a predetermined value at the recording position. The point of application of a force with which at least one of the image recording section and the conveying section is moved by the moving mechanism is substantially coincident with the positioning section.
