A surgical system includes: a tool manipulator having a tool manipulator arm and a surgical tool; a console having a handling tool configured to receive a tool movement input of a surgeon for the surgical tool, the console being configured to transmit a tool movement command generated based on the tool movement input, the tool movement input including a translation amount and a rotation amount for the surgical tool; and a controller. The controller is configured to calculate an actual translation amount by multiplying the translation amount by a predetermined translation scale factor and move the surgical tool in accordance with the actual translation amount, and to calculate an actual rotation amount by multiplying the rotation amount by a predetermined rotation scale factor and move the surgical tool in accordance with the actual rotation amount. The translation scale factor and the rotation scale factor are different values.

Surgical system and method of controlling surgical system

A surgical system includes a surgical assist robot including a robot main body and a slave controller, and a console. The robot main body has an entry guide, an entry guide support device, and at least one manipulator having an end effector provided at a distal end. The entry guide includes an inner cylinder, an outer cylinder into which the inner cylinder is inserted in an insertion axial direction, and a guide advancing device that displaces the inner cylinder in the insertion axial direction with respect to the outer cylinder. While a position and a posture of the end effector that has advanced from the entry guide are maintained, the inner cylinder is caused to advance toward the end effector within a predetermined movable range along the insertion axial direction with respect to the outer cylinder.

Surgical system and method for controlling the same

A surgical system includes a robot main body, a slave controller, a display device that displays an endoscopic image, and an manipulation input device. The robot main body includes an entry guide having a plurality of guide bores, an entry guide support device that supports the entry guide, an instrument manipulator that has a surgical instrument provided at a distal end and is inserted into the entry guide, and an endoscope manipulator that has an endoscopic camera provided at a distal end and is inserted into the entry guide. The slave controller operates the robot main body such that the surgical instrument advances from an exit of the entry guide after the endoscopic camera advances from the exit of the entry guide and starts capturing in response to input of a body cavity insertion manipulation received by the manipulation input device.

A surgical system according to one or more embodiments may include: a plurality of surgical instruments each including a flexible shaft and an end effector; an insertion tube to hold the plurality of flexible shafts and to be inserted into a body of a patient from one end of the insertion tube; and a support device for supporting the plurality of surgical instruments and the insertion tube. The support device includes a plurality of supports respectively supporting the plurality of surgical instruments, a support mechanism supporting the plurality of supports together, and an insertion tube holder holding the insertion tube. The plurality of supports independently and movably support the plurality of surgical instruments, respectively.

Surgical system and support device

A surgical instrument according to one or more embodiments may include: a base; an end effector; an elongated element to drive the end effector; a flexible shaft including a distal end coupled with the end effector; a winding member provided to the base rotatably about a rotational axis orthogonal to the second surface such that the elongated element from the flexible shaft is wound around the winding member; a drive receiving member rotatable about a rotational axis orthogonal to the second surface, to receive drive for rotating the winding member; a first guide pulley; and a second guide pulley. The first guide pulley guides the elongated element drawn from the shaft toward the second guide pulley along the rotational axis of the winding member, and the second guide pulley guides the elongated element from the first guide pulley toward the winding member in a direction intersecting the rotational axis.

Surgical instrument

A surgical tool according to one or more embodiment may include: an end effector; an elongate element that drives the end effector; a hollow shaft that includes a proximal end portion and a distal end portion which is coupled to the end effector; a driving member which the elongate element led via the shaft is wound on; a guide pulley that is disposed between the proximal end portion of the shaft and the driving member and guides the elongate element; and a tension pulley that is disposed between the proximal end portion of the shaft and the guide pulley and biases the elongate element.
