A cannula may include a bowl portion comprising a first opening and a second opening, and an insertion tube extending from the bowl portion. The insertion tube defines a passage extending from the second opening and terminating in a distal end opening. The passage is configured to receive an instrument to be advanced through the cannula. The insertion tube has a transparent portion extending proximally from the distal end opening, and a strengthened portion extending proximally from the transparent portion.

Cannulas having wall strengthening features, and related systems and methods

A computer-assisted medical device includes a first articulated arm, a second articulated arm, an arm stabilizer, and a control system. The arm stabilizer includes first and second clamps and one or more sensors. The first and second clamps are configured to couple the arm stabilizer to the first and second articulated arms. At least one of a distance or a relative orientation between the first and second clamps is adjustable and the one or more sensors are configured to determine the distance or relative orientation. The control system is configured to implement a following mode in which the control system drives movement of the second articulated arm in response to movements of the first articulated arm and the arm stabilizer.

System and method for articulated arm stabilization

A system and method includes deploying first and second articulated arms of a computer-assisted device so that a first attachment point on the first articulated arm and a second attachment point of the second articulated arm are positioned and oriented relative to each other based on a size and a shape of an arm stabilizer; stabilizing and reducing vibration of the first and second articulated arms by attaching the arm stabilizer to the first and second attachment points; after the stabilizing and reducing vibration of the first and second articulated arms, positioning and orienting a tool with the first articulated arm; and after the positioning and orienting of the tool, operating the tool. In some embodiments, the tool is a medical tool. In some embodiments, the system and method further include positioning and orienting a second tool with the second articulated arm and operating the second tool.

A cannula fixation device for insertion at a surgical incision includes a sleeve having a passage configured to receive a cannula, and a clamp configured to rotatably couple the cannula to the sleeve and to maintain an axial position of the cannula relative to the sleeve.

Canula fixation devices, systems, and related methods

A system and method for an articulated arm stabilization includes an arm stabilizer for use with articulated arms of a computer-assisted medical device. The stabilizer includes a spine, a first vibration absorbing mount attached to the spine, a second vibration absorbing mount attached to the spine, a first clamp attached to the first vibration absorbing mount, and a second clamp attached to the second vibration absorbing mount. The first clamp is adapted to hold a first attachment point of a first articulated arm without slipping. The second clamp is adapted to hold a second attachment point of a second articulated arm without slipping. In some embodiments, the arm stabilizer stabilizes and reduces vibration in the first and second articulated arms. In some embodiments, the vibration is in a range from 0.5 to 14 Hz. In some embodiments, the spine limits relative motion between the first clamp and the second clamp.
