Abstract

A distal assembly of an endoscopic surgical device, and a related method, having a first arm and a second arm pivotal relative to the first arm. Each arm is configured to hold a part of a two-part fastener at a distal end of the arm. A closing mechanism is positioned proximate a proximal end of each of the first and second arms opposite the distal end of each of the first and second arms. The dosing mechanism is configured to move in relation to the first and second arms so as to close over at least one of the first and second arms to cause the distal ends of the arms to come together. An actuation member is also attached to the closing mechanism actuable to cause the closing mechanism to move in relation to the first and second arms.

Claims

1. A medical system, comprising:

a flexible endoscope;

an endoscopic tool configured to be guided along the endoscope; and

a stop mechanism located along the endoscope and configured to stop the advancement of the tool at a location relative to the endoscope and prevent further advancement of the tool at the location relative to the endoscope, the stop mechanism being positioned distal of the tool, wherein the endoscope comprises a portion extending distally from the stop mechanism and is configured to articulate and face the tool.

2. The system according to claim 1, wherein the stop mechanism permits proximal motion of the tool relative to the endoscope when the tool and the endoscope are inside a body.

3. The system according to claim 1, wherein the tool comprises a first arm and a second arm, the first and second arms being connected at a connected end, each of the first and second arms having a free end holding a part of a two-part fastener, and the connected end being positioned distally of the free end of each of the first and second arms.

4. The system according to claim 3, further comprising:

a closing mechanism positioned proximate the connected end of the first and second arms.

5. The system according to claim 4, further comprising:

an actuating member configured to move the closing member toward the free end of each of the first and second arms.

6. The system according to claim 4, further comprising:

an actuating mechanism configured to move the closing mechanism toward the proximal end of the endoscope to actuate the tool to cause the arms to come together and the parts of the two-part fastener to mate and fasten tissue.

7. The system according to claim 1, wherein the stop mechanism is a ring.

8. The system according to claim 1, wherein the endoscopic tool further comprises a sleeve, and the sleeve is configured to abut the stop mechanism.

9. A medical system, comprising:

a flexible endoscope;

a tissue fastening tool configured to be guided along the endoscope, the tissue fastening tool comprising a longitudinal axis, an arm connected to a remainder of the tissue fastening tool at a connected end, the arm having a free end holding a fastener, and the connected end being positioned distally of the free end relative to the longitudinal axis;

a closing mechanism positioned proximate the connected end; and

an actuating member configured to move the closing mechanism toward the free end of the arm.

10. The system according to claim 9, further comprising:

a stop mechanism located along the endoscope and configured to stop the advancement of the tissue fastening tool at a location relative to the endoscope, the stop mechanism being positioned distal of the tissue fastening tool.

11. The system according to claim 10, wherein the stop mechanism permits proximal motion of the tissue fastening tool relative to the endoscope when the tissue fastening tool and the endoscope are inside a body.

12. The system according to claim 11, wherein the stop mechanism includes a ring.

13. A medical system, comprising:

a tissue fastening tool configured to be guided through a natural orifice, the tissue fastening tool includes a pair of arms, each arm holding a part of a two-part fastener;

a closing mechanism configured to actuate the tissue fastening tool; and

an actuating mechanism configured to pull the closing mechanism toward a proximal end of the tissue fastening tool and over the pair of arms to actuate the tissue fastening tool to cause the arms to come together and the parts of the two-part fastener to mate and fasten tissue.

14. The system according to claim 13, wherein when actuating the tissue fastening tool, the closing mechanism is configured to contact an outer surface of at least one of the first and second arms that faces away from the outer of the first and second arms.

15. The system according to claim 13, further comprising an endoscope including a stop mechanism configured to stop the advancement of the tissue fastening at a location relative to the endoscope, the stop mechanism being positioned distal of the tissue fastening tool.

16. The system according to claim 15, wherein the stop mechanism permits proximal motion of the tissue fastening tool relative to the endoscope when the tissue fastening tool and the endoscope are inside a body.

17. The system according to claim 13, wherein the first and second arms are connected at a connected end, each of the first and second arms having a free end holding the part of the two-part fastener, and the connected end being positioned distally of the free end of each of the first and second arms.

18. The system according to claim 17, further comprising:

a spring positioned at the connected end of the first and second arms.
