A cycling suturing and knot-tying device 1 is characterized by an arcuate fixed, grooved or recessed way 102 providing in a correspondingly-shaped support frame 775 for accomodating a curved needle 50 fitted with thread, and frictional needle-engaging devices 112 provided in the way 102 for selectively engaging the needle 50 and driving the needle 50 in one or both rotational directions to suture a wound with the thread. A pistol-grip operating apparatus 1267 having a transmission tube 1200 that mounts the frame 775 and the way 102 in articulating relationship and rotates and articulates with respect to the pistol grip 1267 carries various operating elements that inerface with the frictional needle-engaging devices 112 in the way. In at least one embodiment, needle direction-adjusting elements 134, 136 are provided in the frame 775 in cooperation with selected devices in the way 102 for determining the direction of needle rotation. Auxiliary thread-handling or incrementing and knot-tying devices 1101, 1000 are also disclosed. |
