Surgical anchor and system
View Patent ↗The present invention is a device and system for manipulating a surgical tool at an intended location, e.g., a confined or inaccessible space, which includes a surgical anchor having at least one opening, wherein the opening provides a catch for a pin; and at least one anchor point to position and orient a surgical tool inside a human body. The apparatus and system of the present invention allows for the use of multiple intra-abdominal surgical tools inserted through a single incision.
1. A magnetic surgical anchor system comprising:
an elongated member adapted for delivery via a trocar into a body cavity having a wall, the elongated member having a top surface and a bottom surface, at least one pad selected from one of a ferrous, ferromagnetic and magnetic materials inserted into the top surface, an opening for receiving and securing a pin, and an attachment member for attaching a surgical tool;
a pin adapted to engage the opening in the elongated member; and
an external casing comprising at least one magnetic stack, the casing adapted to allow magnetic cooperation with the elongated member when the elongated member is within the body cavity, the casing comprising a pin attachment channel, wherein the elongated member is positioned by movement of the casing external to the cavity and is secured by inserting the pin through the pin attachment channel through the cavity wall and into the opening in the elongated member.
2. The system of claim 1 , wherein the elongated member has a diameter of between 12 and 15 mm.
3. The system of claim 1 , wherein the opening of the elongated member comprises at least one of a catch, a self-locking catch or is threaded, for semi-permanent Anchoring of the pin to the elongated member.
4. The system of claim 1 , further comprising a surgical tool selected from at least one of a camera, a retractor, a paddle, a hose, a cutting tool, a light, a hook or a net.
5. The system of claim 1 , wherein the pin delivers at least one of electrical or pneumatic power to the surgical tool.
6. The system of claim 1 , wherein the elongated member comprises at least one of surgical grade plastic, aluminum, titanium, stainless steel, nylon or polyester.
7. A magnetic surgical anchor system comprising:
an elongated member adapted for delivery via a trocar into a body cavity having a wall, the elongated member having a top surface and a bottom surface, at least one pad selected from one of a ferrous, ferromagnetic and magnetic materials inserted into the top surface, an opening for receiving and securing a pin, and a surgical tool;
a pin adapted to engage the opening in the elongated member; and
an external casing comprising at least one magnetic stack, the casing adapted to allow magnetic cooperation with the elongated member when the elongated member is within the body cavity, the casing comprising a pin attachment channel, wherein the elongated member is positioned by movement of the external casing to the cavity and is secured by attaching the pin to the channel, through the cavity wall and into the opening in the elongated member.
8. The system of claim 7 , wherein the elongated member has a diameter of between 12 and 15 mm.
9. The system of claim 7 , wherein the elongated member comprises at least one of surgical grade plastic, aluminum, titanium, stainless steel, nylon or polyester.
10. A magnetic surgical anchor system comprising:
an elongated member adapted for delivery via a trocar into a body cavity having a wall, the elongated member having a top surface and a bottom surface, at least one pad selected from one of a ferrous, ferromagnetic and magnetic materials inserted into the top surface, an opening for receiving and securing a pin, and a surgical tool;
a pin and pin lock wherein the pin lock is positioned in the opening of the elongated member and adapted to engage the pin; and
an external casing comprising at least one magnetic stack, the casing adapted to allow magnetic cooperation with the elongated member when the elongated member is within the body cavity, the casing comprising a pin attachment channel therethrough adapted to receive the pin and a channel pin lock, wherein the elongated member is positioned by movement of the casing external to the cavity and secured by inserting the pin through the channel in the casing, through the cavity wall and into the opening in the elongated member.
11. The system of claim 10 , wherein the elongated member has a diameter of between 12 and 15 mm.
12. The system of claim 10 , wherein the opening of the elongated member comprises at least one of a catch, a self-locking catch or is threaded for semi-permanent anchoring of the pin to the elongated member.
13. The system of claim 10 , wherein the surgical tool comprises at least one of a camera, a retractor, a paddle, a hose, a cutting tool, n light, a hook or a net.
14. The system of claim 10 , wherein the pin delivers at least one of electrical or pneumatic power to the surgical tool.
15. The system of claim 10 , wherein the elongated member comprises at least one of surgical grade plastic, aluminum, titanium, stainless steel, nylon or polyester.
