Pelvic implant needle system and method
View Patent ↗Various embodiments of a trocar or needle system for use in inserting and deploying pelvic implants are provided. The needle device can include a solid or hollow shaft portion with a non-circular cross-section. A grip element can be provided to slide along a length of the needle shaft to further facilitate handling.
1. An implant introduction system, comprising:
an implant introduction device, including;
a handle having a handle abutment portion having a peripheral edge;
a needle having a distal tip, and a curved shaft defining a needle bend, the curved shaft having a first side, and a second side opposite to the first side, the first side being flat, the second side being curved, the first side of the curved shaft facing towards an inside of the needle bend;
a gripping device configured to slide along a length of the curved shaft, and having:
a gripping abutment portion having a peripheral edge substantially matching a size and shape of the peripheral edge of the handle abutment portion;
an actuation button configured to selectively control sliding of the gripping device along the curved shaft;
a lumen having a cross-sectional shape that matches a cross-sectional shape of the curved shaft, and configured to receive the curved shaft to restrict rotational movement about the curved shaft; and
an implant having a support portion, a first arm portion, and a second arm portion, the implant having a first anchor coupled to the first arm portion, and a second anchor coupled to the second arm portion, the first anchor defining an aperture configured to receive the distal tip of the needle.
2. The system of claim 1 , wherein the implant is a mesh sling.
3. The system of claim 1 , wherein at least the shaft of the needle is constructed of metal.
4. The system of claim 1 , wherein the curved shaft includes a third side, and a fourth side opposite to the third side, the third side being curved, the fourth side being curved.
5. The system of claim 4 , wherein the second side, the third side, and the fourth side, collectively, define a semi-circle shape.
6. The system of claim 1 , wherein, when the actuation button is pressed, the actuation button is configured to stop a sliding of the gripping device, wherein, when the actuation button is released, the gripping device is configured to slide along the length of the curved shaft.
7. The system of claim 1 , wherein the first arm portion and the second arm portion are separate constructs from the support portion.
8. An implant introduction system, comprising:
an implant introduction device, including;
a handle having a handle abutment portion having a peripheral edge;
a needle having a distal tip, and a curved shaft defining a needle bend, the curved shaft having a first side, and a second side opposite to the first side, the first side being flat, the second side being curved, the cross-sectional shape of the curved shaft having a horizontal dimension in a range of approximately 0.150 inches to 0.175 inches and a vertical dimension in a range of approximately 0.125 inches to 0.150 inches;
a gripping device configured to slide along a length of the curved shaft, and having:
a gripping abutment portion having a peripheral edge substantially matching a size and shape of the peripheral edge of the handle abutment portion;
an actuation button configured to selectively control sliding of the gripping device along the curved shaft;
a lumen having a cross-sectional shape that matches a cross-sectional shape of the curved shaft, and configured to receive the curved shaft to restrict rotational movement about the curved shaft; and
an implant having a support portion, a first arm portion, and a second arm portion, the implant having a first anchor coupled to the first arm portion, and a second anchor coupled to the second arm portion, the first anchor defining an aperture configured to receive the distal tip of the needle.
