Claims6
An apparatus for suturing comprising a housing and means on said housing for supporting and driving an arcuate needle around a circular path comprising;
- a plurality of drive rollers spaced along said circular path, speed-reducing gearing including a worm gear having a central bore for receiving a drive shaft, a handle unit including a drive shaft, and means providing a quick-disconnect between said housing and said handle unit and also between said needle driving means and said drive shaft.
An apparatus for sutring comprising housing means, means on said housing means defining a circular path, a curved needle having a pointed front end and a trailing end connectable with a suture thread or the like, said curved needle having a length for extending at least 270 degrees and being disposed for movement around said circular path, said means defining said circular path including more than two drive elements for engaging and driving said needle, said drive elements being spaced around said path so that at least two of said drive elements are always in driving engagement with said needle, at least certain of said drive elements comprising roller means having generally V-shaped peripheral grooves presenting opposed sides surfaces for embracing and frictionally engaging opposite sides of the needle, said roller means comprising first and second separate opposite side parts respectively presenting said opposed side surfaces, and means resiliently urging said parts toward each other for biasing said side surfaces against said opposite side portions of said needle and drive means on said housing operatively connectable with a motor for driving said drive elements.
