摘要：
A surgical drape 600 for covering at least a portion of a surgical robot arm, and surgical system comprising the drape, comprises an interface portion 602 locatable between the arm and a surgical instrument (when the instrument is engaged with the arm) and a bulk portion 601 encompassing the interface portion and adjacent to it. The interface portion may comprising one or more of (i) a material or configuration having a lower modulus than that of the bulk portion in at least one direction (e.g. a resilient or elasticated material), and (ii) a movable portion (e.g. a concertinaed section of material 800, Fig 8), which is movable relative to the bulk portion, so as to permit repeatable movement of a portion of the interface portion relative to the bulk portion. The drape can be further coupled with a tension sensor (721/722, Fig 7a), in communication with a control unit of a surgical system, for sensing tension of/force applied to the material of the interface portion.
