Abstract
A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.
Claims16
A laparoscopic suturing device comprising:
- a handle assembly having a proximal end and a distal end, the handle assembly comprising a trigger mechanism, a closure mechanism, and a toggle mechanism;
- an elongate shaft extending distally from the distal end of the handle assembly and defining a central longitudinal axis;
- a jaw assembly extending distally from the elongate shaft, the jaw assembly comprising a first jaw and a second jaw each having a proximal end pivotably coupled to the elongate shaft and a distal end;
- and
- a needle;
- wherein the trigger mechanism is operably coupled to the closure mechanism and the toggle mechanism such that an actuation cycle of the trigger mechanism sequentially actuates the closure mechanism to close the first jaw and the second jaw of the jaw assembly, actuates the toggle mechanism to transfer the needle from one of the first jaw and the second jaw to the other of the first jaw and the second jaw, and actuates the closure mechanism to open the first jaw and the second jaw.
A laparoscopic suturing device comprising:
- a handle assembly comprising a handle body having a proximal end and a distal end, the handle assembly comprising a trigger mechanism, a closure mechanism, and a toggle mechanism;
- an elongate shaft extending distally from the distal end of the handle assembly and defining a central longitudinal axis;
- an end effector assembly having a first jaw and a second jaw;
- and
- a needle;
- wherein the trigger mechanism comprises a pair of opposed levers each pivotable with respect to the handle body, each of the levers comprising a drive slot formed therein;
- and
- wherein the closure mechanism comprises:
- a plurality of posts each guided by a corresponding drive slot;
- and
- a drive rod having a proximal end and extending distally from the proximal end the elongate shaft to the end effector assembly, the plurality of posts coupled to the proximal end of the drive rod to operably couple the trigger mechanism to the closure mechanism.
