Abstract

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.

Claims

1. A surgical anchor system comprising:

an elongated member comprising a cavity that contains a material selected from one of a ferrous, ferromagnetic and magnetic materials;

a surgical tool coupled to the elongated member and partially bounded by a portion of the elongated member, the surgical tool being coupled to the elongated member such that a distal end of the surgical tool can travel from a collapsed position to a non-collapsed position through a non-linear path; and

an external casing comprising a magnetic stack;

where the elongated member and the casing are configured to generate a coupling force of at least 500 grams at a distance of 10 millimeters between them; and

where the elongated member is adapted to be positioned within a patient'"'"'s abdominal cavity using the casing positioning outside the patient'"'"'s abdominal cavity.

2. The system of claim 1, where if the surgical tool is in the collapsed position, the elongated member and the surgical tool can pass through a circular perimeter of 15 mm.

3. The system of claim 1, where the surgical tool comprises at least one tool selected from the group consisting of a camera, a retractor, a paddle, a hose, a cutting tool, a light, a hook, and a net.

4. The system of claim 1, where the elongated member comprises two cavities that each contains a material selected from one of a ferrous, ferromagnetic, and magnetic materials.

5. The system of claim 4, where the magnetic stack comprises two openings each containing a magnetic material.

6. The system of claim 5, where the magnetic material is contained in the respective openings in an N-S orientation or an S-N orientation.

7. A surgical anchor system comprising:

an elongated member comprising two cavities that each contains a material selected from one of a ferrous, ferromagnetic and magnetic materials;

a surgical tool coupled to the elongated member such that a distal end of the surgical tool can travel from a collapsed position to a non-collapsed position through a non- linear path, the surgical tool being selected from the group consisting of a retractor, a cutting tool, and a hook;

an external casing comprising a magnetic stack;

where the elongated member and the casing are configured to generate a coupling force of at least 500 grams at a distance of 10 millimeters between them; and

where the elongated member is adapted to be positioned within a patient'"'"'s abdominal cavity using the casing positioning outside the patient'"'"'s abdominal cavity.

8. The system of claim 7, where if the surgical tool is in the collapsed position, the elongated member and the surgical tool can pass through a circular perimeter of 15 mm.

9. The system of claim 7, where the magnetic stack comprises two openings each containing a magnetic material.

10. The system of claim 9, where the magnetic material is contained in the respective openings in an N-S orientation or an S-N orientation.
