Abstract
A cycling suturing and knot-tying device is characterized by an arcuate fixed, grooved or recessed way provided in a correspondingly-shaped support frame for accommodating a curved needle fitted with thread, and frictional needle-engaging devices provided in the way for selectively engaging the needle and driving the needle in one or both rotational directions to suture a wound with the thread. Selective articulation of the frame and the way and driving of the needle in the way by positioning the frictional needle-engaging devices with respect to the needle are typically effected by manipulation of a pistol-grip operating apparatus having a transmission tube that mounts the frame and the way in articulating relationship and rotates and articulates with respect to the pistol grip and carries various operating elements that interface with the frictional needle-engaging devices in the way. In at least one embodiment needle direction-adjusting elements are provided in the frame in cooperation with selected devices in the way for determining the direction of needle rotation responsive to manipulation of an interfacing operating element located on the operating apparatus. Auxiliary thread-handling or incrementing and knot-tying devices are also disclosed.

2. A thread advancing device comprising:
-
a fixed housing adapted for attachment to at least one end of an arcuate suturing device;
a movable housing slidably disposed in said fixed housing;
at least one set of blades movably disposed in said movable housing for selectively engaging the thread; and
a control mechanism connected to said movable housing for causing said blades to selectively engage and disengage the thread responsive to operation of said control mechanism.

3. A suturing device comprising:
-
an arcuate frame having a groove, an arcuate needle slidably disposed within said groove such that the needle can selectively move within the groove, the arcuate needle having an exterior side and an interior side, an engaging means disposed within said frame adapted to engage the interior side and exterior side of the arcuate needle; and
a drive means disposed within the frame, the drive means coupled to the engaging means for selectively moving the needle around the groove and an end of the needle out of and into the groove.

4. A suturing device comprising:
-
an arcuate shaped frame having a groove, a semi-circular needle disposed within the groove, a first one-way engaging means disposed within the groove for selectively urging the needle to move in a first direction, and a drive means disposed within said groove, the drive means being coupled to the engaging means such the drive means selectively moves an end of the needle out and into the groove. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A suturing device comprising:
-
an arcuate housing;
a curved needle for advancing a thread along a path within the arcuate housing;
a plurality of one-way engaging devices adapted to selectively engage the curved needle; and
an arcuate driving means positioned within the arcuate housing wherein the driving means moves along an arcuate path and is adapted to rigidly pivot the plurality of engaging devices causing the plurality of engaging devices to engage the needle. - View Dependent Claims (22)

23. A method of surgically suturing tissue comprising:
-
providing a forked blade with a slot, wherein interior surfaces of the slot are adapted to engage a curved needle, pivoting the forked blade so that engagement between the interior surfaces of the slot and the needle occurs, maintaining the engagement of the forked blade against the needle, driving the blade in a first direction such that the needle is also driven in a first direction, advancing a first end of the needle out of a housing, accepting the first end of the needle into the housing, and coupling a thread to the needle such that the thread is pulled behind the needle as the needle moves out of the housing and back into the housing.
