This project was created on 12/21/2023 and last updated a year ago.

Description

We developed a device which attaches to the end effector of the Smart Tissue Autonomous Robot (STAR) and allows for autonomous suture tensioning management. This design could be used for fully autonomous suturing within a laparoscopic environment. Increasing the level of autonomy in surgical robotic systems will help to standardize patient outcomes and free up surgeons for other tasks. Striving for higher levels of autonomy could be particularly useful in time-consuming and repetitive tasks such as suturing.

Our design is held in place at rest by a torsion spring at the pin joint which allows the device to sweep forwards to pull tension on the thread and then return to its resting position to avoid interference with STAR’s suturing mechanism using only one motor. The device is cable-driven so that the motor can remain outside of the body and has a maximum diameter of 24mm to allow it to fit into a trocar.
