1. A system for traction of tissue, comprising: a clamp comprising a first piece and a second piece, each piece defining an end for engaging tissue and a handling end; andan introduction guide comprising an actuator and a detachment mechanism longitudinally slidable within the introduction guide,wherein the handling end of the first piece of the clamp is detachably attachable to the introduction guide and comprises a portion made of ferromagnetic material, wherein the ferromagnetic material is configured to be at least partially held within the introduction guide, wherein the actuator is configured to retract the detachment mechanism away from the clamp to both release the clamp from the introduction guide and fix the clamp to tissue, and wherein the clamp is spring-biased toward a closed position. 2. The system of claim 1, wherein the clamp is movable between an open position and the closed position, and wherein the actuator is configured to move the clamp between the open and closed positions. 3. The system of claim 2, wherein the first piece and second piece of the clamp are rotatable relative to an axis between the open and closed positions. 4. The system of claim 1, wherein the handling end of the second piece of the clamp is rotatable relative to an axis, and the detachment mechanism comprises a rod held against the handling end of the second piece of the clamp when the introduction guide is assembled with the clamp. 5. The system of claim 1, wherein the actuator comprises an actuator end, the actuator end configured to move toward the clamp to retract the detachment mechanism away from the clamp. 6. The system of claim 1, wherein a predetermined amount of retraction of the detachment mechanism both fixes and releases the clamp. 7. A system for traction of tissue, comprising: an introduction guide comprising a detachment mechanism longitudinally slidable within the introduction guide, wherein a distal end of the introduction guide comprises a tube;a clamp having open and closed positions, wherein the clamp is detachably attachable to the introduction guide; anda remote traction means to position the clamp remotely from outside the body cavity,wherein the introduction guide comprises an actuator configured to move the clamp between the open and closed positions, wherein the actuator is further configured to retract the detachment mechanism away from the clamp to both release the clamp from the introduction guide and fix the clamp to tissue, and wherein the clamp is spring-biased toward the closed position. 8. The system of claim 7, wherein the clamp comprises a ferromagnetic material, and wherein the remote traction means comprises a magnet. 9. The system of claim 8, wherein a magnetic field generated by the remote traction means is adjustable. 10. The system of claim 7, wherein the clamp comprises a first piece and a second piece, each piece defining an end for engaging tissue and a handling end, wherein the handling end of the first piece of the clamp is detachably attachable to the introduction guide. 11. The system of claim 10, wherein the handling end of the first piece of the clamp comprises a portion made of ferromagnetic material. 12. The system of claim 10, wherein the first piece and second piece of the clamp are rotatable relative to an axis between the open and closed positions. 13. The system of claim 7, wherein a magnetic field generated by the remote traction means is between 1,000 G to 10,000 G at about the remote traction means. 14. The system of claim 7, wherein the clamp comprises a first end for engaging tissue, a second end opposite the first end, and a projection coupled therebetween, wherein the detachment mechanism comprises a rod extending longitudinally out of the introduction guide, the rod held against the first end of the clamp when the introduction guide is assembled with the clamp. 15. The system of claim 7, wherein the actuator comprises an actuator end, the actuator end configured to move toward the clamp to retract the detachment mechanism away from the clamp. 16. The system of claim 7, wherein a predetermined amount of retraction of the detachment mechanism both fixes and releases the clamp.
