Embodiment Construction

[0038] 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 connected by revolving joints 303 . The proximal-most limb 302a is coupled to the base by a proximal joint 303a. The proximal-most limb 302a and the other limbs are in turn coupled by a further joint 303 . Suitably, the wrist 304 is made up 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 a surgical instrument 306 . Each joint 303 of the arm has one or more motors 307 that can be used to cause rotational motion at the respective joint and one or more position and / or torque sensors 308 that provide information on Information about the current configuration and / or load at the joint. Suitably, the motor is arranged proximal to the joint from which the motion is driven, so as to improve weight distributio...

Abstract

Surgical Drapes and Surgical Systems. The surgical drape for covering at least a portion of a surgical robotic arm including at least one drive assembly interface element for transmitting drive force between the arm and an instrument engageable with the arm , the drape comprising: an interface portion positionable between the arm and the instrument when the instrument is engaged with the arm; and a body portion surrounding the interface portion; The interface portion and the body portion are adjacent to each other, the interface portion comprising one or more of: a material or construction having a lower modulus in at least one direction than the body portion A modulus of , and a movable portion movable relative to the body portion such that a portion of the interface portion is reproducibly movable relative to the body portion.

Description

technical field [0001] The present invention relates to surgical drapes and surgical systems including surgical drapes. Background technique [0002] It is known to use robots to assist and perform surgery. figure 1 A surgical robot 100 is shown including a base 108 , an arm 102 and an instrument 105 including an end effector 106 . The base supports the robot and is itself rigidly attached to, for example, the operating room floor, the operating room ceiling or the trolley. An arm extends between the base and the instrument. The arm is articulated along its length by a plurality of flexible joints 103 which are used to position the surgical instrument in a desired position relative to the patient 101 . Surgical instruments are attached to the distal end 104 of the robotic arm. Surgical instruments are threaded into the body of patient 101 at port 107 for access to the surgical site. The instrument includes at its distal end an end effector 106 for engaging in medical pr...
