  • Publication number: 20210401524
    Abstract: A surgical tool is provided that includes a hollow shaft and a cable extending within the shaft such that the cable is isolated from external forces imparted to the shaft; the shaft and a carriage are included as links of a 4-bar linkage that also includes first and second side links that are rotatably mounted to the carriage at respective first and second distal pivot axes and that are rotatably mounted to the shaft at respective first and second proximal pivot axes; the segment of the cable extends between a distal pulley rotatably at the carriage and a proximal pulley rotatably mounted at the shaft and a segment of the cable extends within the shaft; a distance between the first distal and first proximal pivot axes matches a distance between an axis of the distal pulley axis and an axis of the proximal pulley such that a rocking motion of the 4-bar linkage due to external force upon the shaft exerts no force upon the cable.

  • Publication number: 20210401523
    Abstract: Control cables in a surgical instrument are kept parallel to the instrument's longitudinal axis to prevent transverse forces from the cables being sensed by a transverse force sensor in the instrument. A surgical instrument includes an elongated hollow shaft having a longitudinal center axis. Multiple cables extend within the shaft. A force sensor includes a beam disposed within the shaft and one or more strain gauges disposed on the beam. A proximal anchor is disposed within the shaft and in contact with a proximal end of the beam. A distal anchor is at the distal end of the shaft and in contact with a distal end of the beam. A cable guide is disposed within the shaft to constrain portions of the multiple cables disposed alongside the beam to movement parallel to the center axis, and so prevent force from the moving cables causing transverse force on the beam.

  • Publication number: 20210353373
    Abstract: A medical device includes a shaft, a beam, a hard stop structure, and a link. A proximal end portion of the beam is coupled to the distal end portion of the shaft and a distal end portion of the beam is coupled to the link. A strain sensor is on the beam. A hard stop structure includes a proximal end portion, a distal end portion, and first opposing stop surfaces. The proximal end portion of the hard stop structure is coupled to a distal end portion of the shaft, and the distal end portion of the hard stop structure is coupled to the link. The first opposing stop surfaces are positioned to limit a lateral range of motion of the distal end of the beam with reference to the proximal end of the beam in a first direction by the first stop surfaces contacting one another.
