Surgical slave robot
A surgical slave robot is disclosed. The surgical slave robot, for performing a surgical operation with a surgical instrument installed on an end portion of a robot arm, can include: a main body; a major support arm that is coupled to the main body such that the major support arm is movable along one direction; a minor support arm rotatably coupled to the major support arm; and a plurality of the robot arms rotatably coupled to the minor support arm. By coupling a twofold support arm of a major and minor support arm to a tower-shaped main body and coupling multiple robot arms to the support arms, the surgical slave robot may be constructed with a compact and slim size that occupies a small amount of space, making it possible to position the surgical robot close to the patient while providing space for the surgeon to access the patient.
1. A surgical slave robot for performing a surgical operation with a surgical instrument installed on an end portion of a robot arm, the surgical slave robot comprising:
a main body;
a major support arm movably coupled to the main body, the major support arm movable along one direction;
a minor support arm rotatably coupled to the major support arm, the minor support arm having an upper surface and a lower surface; and
a plurality of the robot arms rotatably coupled to at least one of the upper and lower surfaces of the minor support arm.
2. The surgical slave robot of claim 1 , wherein the main body is formed as a tower-shaped column configured to be mounted on a floor of an operating room in correspondence to a position of an operating table.
3. The surgical slave robot of claim 1 , wherein the minor support arm is coupled to an end portion of the major support arm by a SCARA system.
4. The surgical slave robot of claim 1 , wherein the minor support arm is tiltably coupled to the major support arm.
5. The surgical slave robot of claim 1 , wherein the robot arm comprises two or more link members axially coupled to each other, and
lines extending from coupling axes between the link members meet at a particular point on an end portion of the instrument.
6. The surgical slave robot of claim 1 , wherein the robot arm comprises at least first and second link members connected to one another by a pivotable connection, each link member having a top surface and a bottom surface, the top surface of a first link member contacting the bottom surface of a second link member at the pivotable connection.
7. The surgical slave robot of claim 1 , wherein the robot arms are connected to the top and bottom surface of the minor support arm.
