Abstract
A tissue suturing system includes: a first roller, a second roller, a first power unit, a second power unit and a suture needle. The suture needle is inserted and clamped between the first and second rollers, having parallel axes, at least one of the two rollers offering active rotation and the two rollers applying a force to the suture needle at the position where it is clamped. The first power unit is configured to provide a position where the first and second rollers are relatively close to each other so that their axes are parallel and the suture needle is clamped. The second power unit provides rotation power for the active rotation, and the suture needle is in form of a curved structure and driven by the active rotation to enter and exit the tissue following a curved direction, having an external exposed position for clamping by the two rollers.
