Dual function suturing apparatus and method
First Claim
1. A suturing device for use endoscopically, comprising:
- a first jaw member, a second jaw member, said first and second jaw members being disposed at a distal end of said suturing device;
an actuator disposed at a proximal end of the suturing device, for actuating the first and second jaw members between a closed orientation, wherein distal ends of the jaw members are disposed in close proximity to one another, and an open orientation, wherein said distal jaw member ends are substantially spaced from one another;
a hollow barrel disposed between said actuator and said first and second jaw members;
a linking member disposed within said hollow barrel, connecting said actuator with one of said first and second jaw members;
a needle carriage which is axially movable between distal and proximal positions at said distal end of said suturing device; and
at least one needle disposed at the distal end of said suturing device, on said needle carriage, said at least one needle being movable between a retracted position and an extended position for passage through tissue grasped between said first and second jaw members.

Abstract
A suturing instrument and method for placing mattress stitches in soft tissues is described. An elongate shaft with a stationary jaw and a moveable jaw disposed at the distal end is coupled to a handle grip at the proximal end configured to manipulate the jaws into open and closed positions. The jaws are configured to allow for atraumatic grasping of soft tissues. The stationary jaw is comprised of a serrated face incorporating apertures through which needles attached to opposite ends of a single strand of suture material may be driven out into and through grasped tissue. The serrated upper jaw is configured with needle catch adapted to accept and capture the needles and suture. The handle is released to open the moveable jaw, the instrument may be withdrawn, trailing the suture, and leaving a mattress stitch in the grasped tissue.
