Abstract
A suturing device includes a cannula, a needle pusher and an actuator mechanism. The cannula includes a needle compartment defining a needle-receiving passage terminating at a distal opening of the cannula and a notch extending from the distal opening into the cannula. The needle pusher includes a wire provided in the cannula. The actuator mechanism operably connects with the needle pusher such that actuation of the actuator mechanism results in movement of the wire within the cannula toward the distal opening.
Claims17
A suturing device comprising:
- a cannula including a main shaft and a distal portion having a needle compartment, a curved section and a notch, the needle compartment defining a needle-receiving passage terminating at a distal opening of the cannula and configured to receive a needle and the notch extending into the cannula from the distal opening and configured to receive a suture attached to the needle;
- a needle pusher including a wire provided in the cannula;
- and
- an actuator mechanism operably connected with the needle pusher, wherein actuation of the actuator mechanism results in movement of the wire in an advance direction within the cannula along a curve within the curved section and the notch being offset from a plane defined by the curve, and the needle compartment being configured such that movement of the wire in the advance direction pushes the needle through the distal opening parallel to or towards the main shaft.
A method of assembly comprising:
- providing a suturing device including
- a cannula including a needle compartment defining a needle - receiving passage terminating at a distal opening of the cannula, a curved section, and a notch extending from the distal opening into the cannula;
- a needle pusher including a wire provided in the cannula;
- and
- an actuator mechanism operably connected with the needle pusher, wherein actuation of the actuator mechanism results in movement of the wire in an advance direction within the cannula along a curve within the curved section and the notch being offset from a plane defined by the curve,
- inserting a needle having a suture attached thereto through the distal opening into the needle-receiving passage with a portion of the suture received in the notch and another portion of the suture extending away from the cannula;
- and
- pulling the suture along the notch to move the needle in a retract direction toward a retracted position in which the needle is retained in the needle-receiving passage.
