Robotics-assisted minimally invasive surgery (RAMIS) helps surgeons to avoid manually palpating organs to locate subsurface tumors. Researchers present a novel instrument compatible with the da Vinci surgical robot that features both a tactile sensor and an ultrasound transducer back-to-back in its end effector. The instrument has an articulated wrist that allows it to efficiently palpate tissue in a wide range of orientations. The use of a custom, disposable tactile sensor avoids deterioration in sensor performance due to repeated sterilization. The instrument can apply a palpation force of up to 14 N in any orientation, allowing its use on various tissue types.
