摘要： A medical instrument including a shaft and an actuated structure mounted at a distal end of the shaft can employ a pair of tendons connected to the actuated structure, extending down the shaft, and respectively wound around a capstan in opposite directions. A passive preload system may maintain minimum tensions in the tendons.

摘要： An instrument system includes actuators, an instrument, and a control system. The instrument includes joints and transmission systems that couple the joints with the actuators. A first joint is distal to a second joint, a first transmission system passes through the second joint to couple to the first joint, and a second transmission system couples to the second joint. The control system is programmed to determine a first tension to be applied by the first transmission system, determine a first estimate of an interaction response that results at the second joint from applying the first tension by the first transmission system, determine a second tension to be applied by the second transmission system based on a first set of parameters, the first set of parameters including the first estimate, and command the actuators such that the first and second transmission systems apply the first and second tensions, respectively.

摘要： Techniques for motion mode management include a computer-assisted device having an input control, a repositionable structure, and a controller coupled to the input control and the repositionable structure. The controller is configured to detect motion of the input control for teleoperating the repositionable structure and in response to determining that the motion of the input control includes a component of motion used to change a mode of operation of the computer-assisted device, temporarily disable changes in the mode of operation of the computer-assisted device based on motion of the input control.

摘要： Embodiments of an actuated cannula seal are disclosed In some embodiments, a cannula seal includes a base portion that engages with a cannula; and a seal portion integrally formed with the base portion, the sealing portion capable of engaging with an instrument shaft, the sealing portion capable of being actuated by an actuator so that the sealing portion is continually in motion relative to the instrument shaft. The actuation of the sealing portion can be accomplished by rotation or vibration of the sealing portion relative to the instrument shaft.

摘要： The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and first and second jaws movably coupled to the shaft. The second jaw comprises a cavity for receiving a staple cartridge and a substantially longitudinal reinforcing wall extending through the cavity. The instrument further includes a drive member configured to translate through the end effector to close the jaws and to engage a plurality of staples within the staple cartridge to drive the staples into tissue. The reinforcing wall provides additional support for the staple cartridge to inhibit deformation of the staple cartridge during actuation, thereby improving the staple formation in the tissue. This improves the tissue seal provided by the staples without increasing the overall size of the end effector.

摘要： A system may comprise a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the system to record shape data for an instrument during an image capture period of an imaging system and receive image data from the imaging system corresponding to the image capture period. A portion of the image data corresponds to the instrument. The computer readable instructions further cause the system to identify a target in the image data, segment the portion of the image data, register the image data to the shape data by comparing the shape data to the portion of the image data corresponding to the instrument, and update a location of the target from a pre-operative location to an intra-operative location based upon the image data.

摘要： Example embodiments include an optical interrogation system with a sensing fiber having a single core, the single core having multiple light propagating modes. Interferometric apparatus probes the single core multimode sensing fiber over a range of predetermined wavelengths and detects measurement interferometric data associated with the multiple light propagating modes of the single core for each predetermined wavelength in the range. Data processing circuitry processes the measurement interferometric data associated with the multiple light propagating modes of the single core to determine one or more shape-sensing parameters of the sensing fiber from which the shape of the fiber in three dimensions can be determined.

摘要： An imaging system includes an illuminator for providing illumination on a region of interest, one or more first detectors for detecting reflections of the illumination, and a processing unit. The processing unit is configured to: receive a first image containing the region of interest; determine a first region of high specular reflection in the first image based on the reflections of the illumination on the region of interest; mask the first image by substituting a default color designating masking to alert a user to incomplete image information in the first region of high specular reflection to create a masked first image; and generate a composite image based on the masked first image and a fluorescence image of the region of interest.

摘要： A medical device may comprise an instrument comprising a shaft and a working end comprising a jaw mechanism, and a translating mechanism moveable in a first direction and a second direction relative to the jaw mechanism, the first and second directions opposite to one another. The medical device may further comprise a controller configured to in response to a first input, control movement of the translating mechanism from a proximal position to an intermediate position relative to the jaw mechanism, in response to a second input, control movement of the translating mechanism from the intermediate position to a distal position relative to the jaw mechanism, control movement of the translating mechanism from the distal position back to the proximal position, and monitor a position of the translating mechanism to determine whether the translating mechanism has moved from the distal position back to the proximal position after a predetermined time period.
