Abstract: A method comprises grasping material between a pair of jaw members of a medical instrument; sensing light transmitted from the material grasped between the pair of jaw members to a location exterior to the pair of jaw members; and altering a grasping force exerted by the pair of jaw members on the material being grasped based on the sensing of the light transmitted.

Abstract: Techniques are disclosed for imaging device control in a viewing system that includes a repositionable structure configured to support an imaging device, and a control unit communicably coupled to the repositionable structure. The control unit is configured to receive head motion signals indicative of a head motion of a head of an operator relative to a reference, and in response to determining that the head motion signals indicate that the head motion does not exceed a threshold amount in a direction, cause a field of view of the imaging device to be adjusted in accordance with a commanded motion by commanding movement of at least one of the repositionable structure or the imaging device, where the commanded motion is determined based on the head motion.

Abstract: A medical apparatus can include an instrument comprising a shaft and a jaw assembly coupled to an end of the shaft; an image capture device; and a controller operably coupled to the image capture device to receive image data from the image capture device. The image data is from images of material gripped between jaw members of the jaw assembly and captured by the image capture device, with the controller programmed to process the received image data using at least one of optical flow and digital image correlation. A medical apparatus can include an instrument comprising a shaft, and a jaw assembly coupled to an end of the shaft, the jaw assembly comprising a pair of jaw members having opposing surfaces configured to grasp material between the opposing surfaces, wherein at least a portion of the opposing surface of a first jaw member of the pair of jaw members is transparent.
