Suture retrieval systems and methods
View Patent ↗A device for threading and automatically retrieving a suture is provided. The device includes a bottom handle having a channel for receiving and retaining a suture, and a top handle having a needle with an opening, the opening configured to receive and retrieve the suture as the device is moved from a closed position to an open position. Related methods of use are also provided.
1 . An automatic suture device comprising:
a needle having a proximal portion and a distal portion, the distal portion of the needle comprising distal a flat section and a needle tip portion with a ramped surface, the proximal portion of the needle comprising a proximal flat section and an opening configured to receive a suture;
a distal end comprising a flat section, a ramped surface, and an aperture capable of receiving the needle;
a proximal end comprising a top handle and a bottom handle; and
a connector comprising a hinge that is at a position between the distal end and the proximal end, wherein the hinge allows for pivoting movement of the top handle and the bottom handle,
wherein the ramped surface of the needle is configured to slidingly engage the ramped surface of the distal end to actuate a needle grasping function,
wherein the flat section of the distal end is configured to engage the distal flat section of the needle to prevent retraction of the needle from the aperture after the distal flat section is advanced past the ramped surface, and
wherein the flat section of the distal end is configured to engage the proximal flat section of the needle to prevent retraction of the needle from the aperture after the proximal flat section is advanced past the ramped surface.
2 . The automatic suture device of claim 1 , wherein the needle tip portion comprises a distal conical section, and wherein the ramped surface is disposed on the distal conical section.
3 . The automatic suture device of claim 1 , wherein the needle tip portion comprises a proximal cylindrical section and a distal conical section, wherein the flat section of the needle is disposed on a proximal surface of the proximal cylindrical section, and wherein the ramped surface is disposed on the distal conical section.
