Abstract: A suturing device comprising a drive shaft and an oscillator for oscillating the drive shaft about an oscillatory axis. A suturing needle is coupled to the drive shaft so that the drive shaft can move the suturing needle back and forth along a first path. A loop arm is mounted for movement along a second path generally transverse to the oscillatory axis. The loop arm is drivingly coupled to the drive shaft to permit the drive shaft to move the loop arm back and forth along the second path.

Abstract: A suturing device for sewing animal skin or flesh having a reversely movable arcuate needle and a pivotal rocker arm, said needle and rocker arm being movable in planes at substantially right angles to each other whereby said rocker arm affords a loop in the suturing thread for each succeeding stitch afforded by the needle. When operating, the device includes a continually operating electric motor having clutch means for engaging and disengaging, as desired, a drive shaft and a driven shaft, the latter affording pivotal movement to the needle by means of an extension on the driven shaft which alternately engages drive elements on a pivotal shaft which is attached to the needle. The rocker arm is driven by the driven shaft by engagement of lugs on the driven shaft and a rocker arm shaft parallel thereto.
