摘要：
A robotic surgical instrument comprising an end effector and an instrument interface having an instrument interface element comprising a body 2200 that is displaceable over a first range. Body 2200 is receivable in a drive assembly interface element of a robot arm. The drive-assembly-interface-element is displaceable over a second range. The length A of the body 2200 in the displaceable direction X is greater than that of the maximum travel of the body 2200 over the first range or the maximum travel of the drive interface element over the second range. Also a surgical robot arm having a drive assembly at its distal end； drive assembly comprising drive interface element for driving an instrument interface element of a robotic surgical instrument. The drive interface element which comprises a socket to receive a body 2200 of the instrument interface element is displaceable over a second range and the instrument interface element is displaceable over a first range. The internal length of the socket in the displaceable direction is greater than the maximum travel of the body 2200 over the first range, or the maximum travel of the socket over the second range. Described as allowing displacement without slippage.
