Embodiment Construction

[0031] image 3 A surgical robot is shown having an arm 300 extending from a base 301 . The arm includes a plurality of rigid limbs 302 . These limbs are linked by a swivel joint 303 . The most proximal limb 302a is coupled to the base by a joint 303a. It is connected in series with the other limbs via a further joint 303 . Suitably, the wrist 304 is comprised of four separate rotational joints. Wrist 304 couples one limb (302b) to the most distal limb (302c) of the arm. The most distal limb 302c carries an attachment 305 for an electrocautery instrument 306 . Each joint 303 of the arm has one or more motors 307 operable to cause rotational motion at the respective joint and one or more position and / or torque sensors 308 provided with position and / or torque sensors 308. information about the current configuration and / or load of the Suitably, the motor is arranged proximal to the joint whose motion is driven by the motor, in order to improve weight distribution. For cla...

Abstract

A robotic surgical instrument comprises a shaft, an electrocautery end effector powered by an electrocautery element, and an articulation connecting the electrocautery end effector to the shaft. The articulation comprises: a first joint driveable by a first pair of driving elements which permits the electrocautery end effector to rotate about a first axis transverse to a longitudinal axis of the shaft; and a second joint driveable by a second pair of driving elements which permits the electrocautery end effector to rotate about a second axis transverse to the first axis. The electrocautery element is constrained to move around the first axis and constrained to wrap at least one full revolution around the second axis. The path of the electrocautery element between the shaft and the second joint symmetrically opposes the path of a first one of the second pair of driving elements between the shaft and the second joint.

Description

Background technique [0001] The use of robots to assist and perform surgery is known. figure 1 A typical surgical robot 100 is shown including a base 108 , arms 102 and instruments 105 . The pedestal supports the robot, and the pedestal itself is securely attached to, for example, an operating room floor, an operating room ceiling or a trolley. An arm extends between the base and the instrument. The arm is articulated along its length by means of a number of flexible joints 103 which are used to position the surgical instrument in a desired position relative to the patient. Surgical instruments are attached to the distal end 104 of the robotic arm. Surgical instruments penetrate the body of patient 101 at port 107 to access the surgical site. The instrument includes at its distal end an end effector 106 for performing a medical procedure. [0002] A variety of end effectors are known, each adapted to perform a particular surgical function. figure 2 Surgical instrument 2...
