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.
Claims15
A laparoscopic suturing system comprising:
- a laparoscopic suturing device comprising:
- a handle assembly;
- an elongate shaft having a proximal end coupled to the handle assembly and a distal end, and defining a central longitudinal axis extending between the proximal end and the distal end;
- and
- a jaw assembly coupled to the distal end of the elongate shaft, the jaw assembly comprising a first jaw and a second jaw each pivotably coupled to the elongate shaft and pivotable between an open configuration and a closed configuration;
- and
- a suturing needle positionable in the jaw assembly, the suturing needle comprising:
- a needle having a generally curved profile and extending from a first penetrating tip to a second penetrating tip, the needle comprising:
- a first shim notch adjacent the first penetrating tip;
- a second shim notch adjacent the second penetrating tip;
- a first recess adjacent the first penetrating tip;
- and
- a second recess adjacent the second penetrating tip;
- and
- a suture coupled to the needle;
- and
- wherein the first jaw further comprises a generally spherical detent engageable with the first recess of the needle to retain the needle in the first jaw.
A laparoscopic suturing system comprising:
- a laparoscopic suturing device comprising:
- an elongate shaft having a proximal end and a distal end, and defining a central longitudinal axis extending between the proximal end and the distal end;
- and
- a jaw assembly coupled to the distal end of the elongate shaft, the jaw assembly comprising:
- a first jaw comprising a first base jaw having a proximal end and a distal end and a first flip jaw pivotably coupled to the distal end of the first base jaw;
- and
- a second jaw comprising a second base jaw having a proximal end and a distal end and a second flip jaw pivotably coupled to the distal end of the second base jaw;
- wherein the proximal end of the first base jaw is pivotably coupled to the proximal end of the second base jaw and to the elongate shaft and wherein the first base jaw and the second base jaw are pivotable between an open configuration and a closed configuration;
- and
- a suturing needle positionable in the jaw assembly, the suturing needle comprising:
- a needle having a generally curved profile and extending from a first penetrating tip to a second penetrating tip;
- and
- a suture coupled to the needle.
