PROBLEM TO BE SOLVED: To provide a suitable indicator for a tool state and a communication in a multi-arm robotic telesurgery.SOLUTION: A device, a system and a method for medical treatment and/or a robot can provide an indicator (20) associated with each of manipulator assemblies (8 and 10) of a multi-arm telerobotic or telesurgery system. An exemplary indicator comprises a multicolor light emitting diode (LED) (56) that is attached to a manipulator for operating an associated surgical instrument (28) and enables the indicator to display various arbitrary signals. The present invention can provide an additional user interface that facilitates a communication between the telesurgery system and/or members (A and O) of a telesurgery team.

PROBLEM TO BE SOLVED: To provide multiple telemanipulation surgical instruments.SOLUTION: A distal end of the surgical instrument can move in all six Cartesian degrees of freedom independently of any other components in a telemanipulation surgical system. The surgical instrument extends through a guide tube. The distal end is moved by an actuator, which is controlled by remote control. Each surgical instrument works independently of the other and has an end effector with at least six actively controlled degrees of freedom in Cartesian space (i.e., surge, heave, sway, roll, pitch, and yaw), via a single entry port in a patient and past intermediate tissue that restricts lateral movement of a rigid instrument body.

PROBLEM TO BE SOLVED: To provide multiple telemanipulation surgical instruments.SOLUTION: A distal end of a surgical instrument 1802 can move in all six Cartesian degrees of freedom independently of any other components in a telemanipulation surgical system. The surgical instrument extends through a guide tube 1804. The distal end is moved by an actuator, which is controlled by remote control. Each surgical instrument works independently of the other and has an end effector with at least six actively controlled degrees of freedom in Cartesian space (i.e., surge, heave, sway, roll, pitch, and yaw), via a single entry port in a patient and past intermediate tissue that restricts lateral movement of a rigid instrument body.
摘要:
The present invention is directed to a tool having a wrist mechanism that provides pitch and yaw rotation in such a way that the tool has no singularity in roll, pitch, and yaw. A positively positionable multi-disk wrist mechanism includes a plurality of disks or vertebrae stacked in series. Each vertebra is configured to rotate in pitch or in yaw with respect to each neighboring vertebra. Actuation cables are used to manipulate and control movement of the vertebrae. In specific embodiments, some of the cables are distal cables that extend from a proximal vertebra through one or more intermediate vertebrae to a distal vertebra, while the remaining cables are medial cables that extend from the proximal vertebra to one or more of the intermediate vertebrae. The cables are actuated by a pivoted plate cable actuator mechanism.; In specific embodiments, the actuator mechanism includes a plurality of small radius holes or grooves for receiving the medial cables and a plurality of large radius holes or grooves for receiving the distal cables. The holes or grooves restrain the medial cables to a small radius of motion and the distal cables to a large radius of motion, so that the medial cables to the medial vertebra move only a fraction of the amount as the distal cables to the distal vertebra, so as to achieve precise control and manipulation of the vertebrae.

PROBLEM TO BE SOLVED: To provide a plurality of teleoperative surgical instruments.SOLUTION: A distal end of a surgical instrument can move all six degrees of freedom in Cartesian coordinates regardless of other components of teleoperative surgical instruments. The surgical instrument extends through a guide tube 1952. The distal end is moved by an actuator and the actuation is controlled by teleoperation. Each surgical instrument works independently from the other surgical instruments, and each has an end effector that passes through a single inlet port of a patient, and passes an intermediate tissue restricting lateral motion of a hard instrument body, the end effector having at least actively-controlled six degrees of freedom (namely, surge, heave, sway, roll, pitch, and yaw) in the Cartesian coordinates.
