Abstract

Methods, systems, devices and assemblies are provided for treating a patient by: making an incision or puncture though the patient'"'"'s skin over the abdominal cavity; establishing an initial tract through an opening formed by the incision or puncture; advancing an instrument through the tract; contacting a distal end portion of the instrument against an inner surface of the abdominal cavity; driving at least one stitching needle through the inner surface of the abdominal cavity; continuing the driving until the at least one stitching needle exits the inner surface of the abdominal cavity; anchoring a suture carried by each of the at least one stitching needle to a suture anchor at an exit location, respectively; and applying tension to each of the sutures.

Claims

1. A surgical instrument comprising:

an elongate shaft;

a working end platform formed on a distal end portion of said elongate shaft;

a handle mounted on a proximal end portion of said elongate shaft;

a stitching needle rotatably mounted relative to said platform and rotatable from a concealed position in which a tip of said stitching needle is concealed within said platform to an exit position where said tip is inserted into a suture anchor releasably attached to said platform, and counter-rotatable from said position where said tip is inserted into said suture anchor to said position in which said tip is concealed within said platform; and

a stabilizing pin movably mounted to said platform, said stabilizing pin being actuatable from a recessed position in which a tip of said stabilizing pin is concealed within said platform to a stabilizing position where said tip extends out of said platform, and vice versa.

2. The instrument of claim 1, wherein said stabilizing pin, in said stabilizing position angles away from a direction of movement of said stitching needle as said stitching needle moves from said concealed position to said exit position.

3. The instrument of claim 1, further comprising a stabilizing pin actuator, operable by a user from a location proximal of said elongate shaft, said stabilizing pin actuator configured to actuate said stabilizing pin to move from said recessed position to said stabilizing position and vice versa;

and

a stabilizing pin mechanism extending from said actuator to said stabilizing pin, along said elongate shaft, said stabilizing pin mechanism configured to drive as well as retract said stabilizing pin.

4. The instrument of claim 1, further comprising a stitching needle actuator, operable by a user from a location proximal of said elongate shaft, said stitching needle actuator configured to actuate said stitching needle to move from said concealed position to said exit position;

and

a stitching needle mechanism extending from said actuator to said stabilizing pin, along said elongate shaft, said stitching needle mechanism configured to drive said stitching needle from said concealed position to said exit position.

5. The instrument of claim 4, further comprising a stitching needle retraction mechanism configured to automatically counter-rotate said stitching needle from said exit position to said concealed position, after said stitching needle has reached said exit position.

6. The instrument of claim 3, further comprising a safety mechanism configured for actuation from a safe position and a release position, wherein in said safe position, said stabilizing pin actuator is prevented from actuating said stabilizing pin to move from said recessed position to said stabilizing position, and, when in said release position, said safety mechanism allows said stabilizing pin actuator to actuate said stabilizing pin to move from said recessed position to said stabilizing position.

7. The instrument of claim 4, further comprising a safety mechanism configured for actuation from a safe position and a release position, wherein in said safe position, said stitching needle actuator is prevented from actuating said stitching needle to move from said concealed position to said exit position, and, when in said release position, said safety mechanism allows said stitching needle actuator to actuate said stitching needle to move from said concealed position to said exit position.

8. The instrument of claim 4, wherein said stitching needle mechanism comprises a ratchet mechanism, and said stitching needle actuator ratchets to incrementally rotate said stitching needle from said concealed position to said exit position.

9. The instrument of claim 4, further comprising a bailout mechanism, configured for operation by a user from a location proximal of said elongate shaft, wherein said bailout mechanism is operable to disconnect said stitching needle actuator from said stitching needle mechanism, and to counter-rotate said stitching needle.
