A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a needle driver at a distal end of the drive arm, wherein the needle driver is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the needle driver, thereby rotating the suturing needle about the rotational axis.

1. A motorized suturing device for tissue closure comprising: a handle having a proximal end and a distal end, said handle defining and surrounding an enclosable elongate compartment therein, said enclosable elongate compartment being adjustable from an open condition wherein said enclosable elongate compartment is exposed to the environment outside said enclosable elongate compartment to an enclosed condition wherein said enclosable elongate compartment defines a sterile barrier that isolates said enclosable elongate compartment from the environment outside said enclosable elongate compartment;a pusher assembly extending distally from said distal end of said handle, said pusher assembly having (i) a drive arm extending distally from a drive shaft and (ii) a needle driver at a distal end of said drive arm, wherein said needle driver is capable of releasably engaging and advancing an arcuate suturing needle having a pointed end and a second end around a circular needle track about a rotational axis;a removable needle cartridge having a protective housing for receiving the arcuate suturing needle, said removable needle cartridge extending distally from a distal region of a cartridge holder assembly, said cartridge holder assembly being connected to and extending distally of said handle, said removable needle cartridge being releasably attached to said cartridge holder assembly, wherein said pusher assembly is rotatably guided within said cartridge holder assembly so that the pointed end of the suturing needle is positioned within said protective housing before and after a complete rotation of the suturing needle about said rotational axis; andan elongate removable electronic module that is removably disposable in said enclosable elongate compartment, said enclosable elongate compartment forming a sterile barrier around said elongate removable electronic module when said handle is in the enclosed condition, said elongate removable electronic module having an actuator that mechanically engages said drive shaft via a coupling to rotate said drive shaft and said needle driver, thereby advancing the suturing needle about the rotational axis, said removable electronic module including: (i) a power source for providing power to said electronic module;(ii) a motor and a gear box adapted to selectively provide rotational force to rotate said drive shaft and said needle driver to advance the suturing needle;(iii) an electronics board that controls operation of said electronic module, wherein said coupling is arranged and configured so as to releasably engage said electronic module in axial alignment of the rotational axis of said drive arm of said pusher assembly; and(iv) Hall-effect sensor configured and arranged to detect the rotational position of at least one magnet configured to rotate in synchronization with said drive shaft. 2. The motorized suturing device of claim 1, wherein said drive shaft includes a drive plate defining a hole therein, and wherein said actuator includes a drive wheel with a drive pin and with a bushing so that upon assembly of said electronic module with said pusher assembly said drive pin engages said hole and said drive shaft engages said bushing. 3. The motorized suturing device of claim 2, wherein said drive wheel is rotatably guided on a bearing surface arranged on a stop plate of said actuator. 4. The motorized suturing device of claim 3, wherein said stop plate defines a track therein in which said drive pin rides. 5. The motorized suturing device of claim 4, wherein said track defines the shape of an arc with two stopping points at both ends of the arc so as to limit the rotational travel of said drive pin to about 190°. 6. The motorized suturing device of claim 2, wherein said drive wheel includes at least two magnets configured and arranged to be used in conjunction with the Hall-effect sensor to detect the rotational travel of said drive wheel. 7. The motorized suturing device of claim 6, wherein said magnets are arranged relative to said track to sense the approach of said drive pin with respect to said stopping points. 8. The motorized suturing device of claim 1, wherein said drive shaft includes a torsion spring associated therewith to return said drive plate into a starting position upon disengagement. 9. The motorized suturing device of claim 1, wherein said cartridge includes: a housing having a curved shape, an inner wall and an outer wall;a track defined in the inner wall of the housing wherein the suturing needle follows a curved path along the track during a revolution of the suturing needle; andan aperture in the housing that intercepts the track, wherein the housing shields the pointed end of the suturing needle during at least a portion of the revolution of the suturing needle. 10. The motorized suturing device of claim 9, wherein the track is intercepted by said aperture so that the track covers an arc greater than about 180° and less than about 330°. 11. The motorized suturing device of claim 10, wherein the suturing needle is arcuate and has a radius commensurate with a rotational radius of the needle driver of the pusher assembly. 12. The motorized suturing device of claim 11, wherein the cartridge includes an anti-rotate and locking bar capable of engaging the suturing needle so as to prevent rotation of the suturing needle in a direction opposite to the advancing direction. 13. The motorized suturing device of claim 12, wherein said anti-rotate and locking bar is configured and arranged to engage with the cartridge holder assembly such that the aperture in the cartridge is configured to be aligned with an aperture in the cartridge holder assembly. 14. The motorized suturing device of claim 1, wherein the gear box provides a reduction in gearing of about 100:1 for torque increase. 15. The motorized suturing device of claim 1, wherein said cartridge holder assembly includes an anti-backup mechanism arranged between said cartridge holder assembly and said protective housing so as to contact the suturing needle such so as to preclude any dislocation of said suturing needle apart from its rotation about the rotational axis, the anti-backup mechanism including a pawl that permits circular movement of the needle driver that engages the suturing needle. 16. The motorized suturing device of claim 1, wherein the proximal end of the cartridge holder assembly is encased by a nose collar, which is attached to a sterile handle for receiving the electronic module.
