摘要： Disclosed embodiments include apparatuses, systems, and methods for driving a needle to facilitate suturing, such as may be performed in a surgical anastomosis procedure. In an illustrative embodiment, an apparatus includes a frame. First and second rollers are rotatably mounted parallel with each other in the frame and are configured to engage therebetween a shaft of a needle formed in a helical shape. The first and second rollers are configured to counter-rotate. The needle is revolvable eccentrically around the first roller responsive to counter-rotation of the first and second rollers. A drive mechanism is secured to the frame and is configured to move the frame.
