  • Publication number: 20240277435
    Abstract: A surgical tool includes a drive housing having opposing distal and proximal ends, first and second drive cable capstans arranged within the drive housing and asymmetrically aligned between the distal and proximal ends, a first drive cable extending distally from the drive housing and actuatable by operation of the first drive cable capstan, and a second drive cable extending distally from the drive housing and actuatable by operation of the second drive cable capstan. A stiffness of the first and second drive cables is equalized by adjusting one or more characteristics of one or both of the first and second drive cables.

  • Publication number: 20240277436
    Abstract: A surgical tool includes a drive housing, a drive input rotatably mounted to a bottom of the drive housing, a capstan assembly arranged within the drive housing and operatively coupled to the drive input such that rotation of the drive input correspondingly actuates the capstan assembly, a static actuation limiter arranged within the drive housing, and a dynamic actuation limiter provided by the capstan assembly and engageable with the static actuation limiter as the capstan assembly is actuated. Engaging the dynamic actuation limiter against the static actuation limiter stops actuation of the capstan assembly.

  • Publication number: 20240277437
    Abstract: An articulated member for a surgical instrument, the articulated member including: first proximal and distal joints, each rotatable about a respective axis that extends across a first rotation plane extending longitudinally through the articulated member; second proximal and distal joints, each rotatable about a respective axis that extends across a second rotation plane extending longitudinally through the articulated member perpendicularly to the first rotation plane so that the second proximal and distal joints are rotatable orthogonally relative to the first proximal and distal joints; and a plurality of coupling tendons extending through the articulated member via respective coupling tendon receiving portions. Each coupling tendon extends along the articulated member substantially spaced apart from both the first and second rotation planes so that rotation of one of the proximal and distal joints causes rotation of the other of the respective proximal and distal joints.

  • Publication number: 20240277445
    Abstract: An implantable tissue marker device is provided to be placed in a soft tissue site through a surgical incision. The device can include a bioabsorbable body in the form of a spiral and defining a spheroid shape for the device, the spiral having a longitudinal axis, and turns of the spiral being spaced apart from each other in a direction along the longitudinal axis. A plurality of markers can be disposed on the body, the markers being visualizable by a radiographic imaging device. The turns of the spiral are sufficiently spaced apart to form gaps that allow soft tissue to infiltrate between the turns and to allow flexibility in the device along the longitudinal axis in the manner of a spring.
