Abstract

A hand-held gripping device that allows one of a surgeon, a dentist, and an orthodontist to reach interior portions of a person'"'"'s anatomy, includes a gripping portion having a pair of jaws or nets movable relative to each other between fully clamped and fully opened positions thereof, a handle portion spaced apart from the jaw portion by a bendable central portion that has a hollow, bendable corrugated member with at least one cord extending therethrough. The retrieval of a thrombus to promptly address ischemic issues is made possible due to the flexible corrugated member being able to access small vessels in a patient'"'"'s brain, as well as magnetic properties of the thrombus and/or jaws, nets, bags, or flexible fingers, of the grasping end, thus facilitating removal of the thrombus.

Claims

1. A selectively bendable remote gripping tool comprising a pair of net assemblies movable relative to each other between closed and opened positions;

a sharp cutting implement associated with said pair of net assemblies, said sharp cutting implement positioned within an interior volume defined by the pair of net assemblies to perform a severing operation when said pair of net assemblies are in said closed position;

a handle portion spaced apart from the pair of net assemblies by a central portion, the handle portion comprising a first actuatable trigger operatively connected to the pair of net assemblies by a pull member at least substantially disposed within the central portion and that extends through the central portion, whereby actuation of the trigger is operative to move the pull member to thereby selectively position the pair of net assemblies between the closed and opened positions;

wherein the central portion comprises linked ball and socket jointed elements forming a plurality of interconnected connectors, thereby permitting pivoting movement with respect to said interconnected connectors.

2. The tool as set forth in claim 1, wherein the actuatable trigger comprises a manually operable release trigger.

3. The tool as set forth in claim 1, wherein said sharp cutting implement comprises a pair of cutting blades.

4. The tool as set forth in claim 1, further comprising a locking member associated with said central portion to fix two adjacent interconnected connectors in an engaged position, said locking member operable between a first locking position and a second unlocking position.

5. The tool as set forth in claim 1, wherein the central portion comprises glow in the dark material.

6. The tool as set forth in claim 1 wherein said pair of net assemblies are reversibly disassociable to accommodate different types, designs, sizes, mesh patterns, and geometries of net attachments.

7. The tool as set forth in claim 1, wherein said pair of net assemblies form a five-sided net.

8. The tool as set forth in claim 1, wherein said pair of net assemblies comprises one structure with a loose net and an opposing paired structure with a taut net.

9. The tool as set forth in claim 1, further including a lighting source positioned at a distal end of the tool.

10. The tool as set forth in claim 1, further including a distally positioned camera.

11. The tool as set forth in claim 1, further including a magnifying viewing device.

12. The tool as set forth in claim 1, wherein the sharp cutting implement is operable via a cord extending through the central portion.

13. A selectively bendable remote gripping tool comprising a pair of net assemblies movable relative to each other between closed and opened positions;

a pair of sharp cutting implements movable relative to each other between closed and opened positions thereof and being associated with said pair of net assemblies, said pair of sharp cutting implements being positioned within an interior volume defined by the pair of net assemblies to perform a severing operation when said pair of net assemblies are in said closed position;

a handle portion spaced apart from said pair of net assemblies by a central portion, the handle portion comprising a first actuatable trigger operatively connected to the pair of net assemblies by a pull member at least substantially disposed within the central portion and that extends through the central portion, whereby actuation of the trigger is operative to move the pull member to thereby selectively position the pair of net assemblies between the closed and opened positions;

wherein the central portion comprises linked ball and socket jointed elements forming a plurality of interconnected connectors, said central portion being bendable so as to position said tool into a desired configuration.

14. The tool as set forth in claim 13, wherein said pair of sharp cutting implements comprise a cutting blade.

15. The tool as set forth in claim 13, wherein said pair of sharp cutting implements comprise sharpened cutting jaws.

16. The tool as set forth in claim 13, further including a lighting source positioned at a distal end of the tool.

17. The tool as set forth in claim 13, wherein said tool has at least one magnet positioned on a distal end of the tool.

18. The tool as set forth in claim 13, further including a magnifying viewing device.

19. The tool as set forth in claim 13, wherein the actuatable trigger comprises a manually operable release trigger.

20. A selectively bendable remote gripping tool comprising:

a pair of net assemblies movable relative to each other between closed and opened positions;

a sharp cutting implement associated with said pair of net assemblies, said sharp cutting implement positioned within an interior volume defined by the pair of net assemblies to perform a severing operation when said pair of net assemblies are in said closed position;

a handle portion spaced apart from the pair of net assemblies by a central portion, the handle portion comprising a first actuatable trigger operatively connected to the pair of net assemblies by a pull member at least substantially disposed within the central portion and that extends through the central portion, whereby actuation of the trigger is operative to move the pull member to thereby selectively position the pair of net assemblies between the closed and opened positions;

wherein the central portion comprises linked ball and socket jointed elements forming a plurality of interconnected connectors, thereby permitting pivoting movement with respect to said interconnected connectors, wherein at least a portion of said central portion is in telescoping relationship with an adjacent portion of said central portion.
