Claims
- 1. An endosurgical device, comprising:
- a retraction portion having a first end and a second end and a flattened plate between said first and second ends, said first end including an edge for engaging tissue, said flattened plate configured to atraumatically retract tissue;
- a curved shaft having a proximal end and a distal end, said distal end attached to said second end of said retraction portion, said shaft having a first bend subtending an angle of at least about 120 degrees; and
- a gripping portion attached to said proximal end of said shaft, said gripping portion configured for manually gripping and manipulating the device;
- wherein said edge of said retraction portion forms a third angle with said flattened plate, said third angle being between about 90 and about 150 degrees.
- 2. The device of claim 1, wherein said first angle is about 160 degrees.
- 3. The device of claim 1 wherein said proximal end of said shaft includes a second bend, said second bend bending said gripping portion in a direction away from said retraction portion, said second bend, said gripping portion and said shaft forming a second angle of at least 90 degrees.
- 4. The device of claim 3 wherein said second angle is about 110 degrees.
- 5. The device of claim 1 wherein said third angle is about 135 degrees.
- 6. The device of claim 1 wherein said plate portion has a width that is greater than a diameter of said shaft.
- 7. The device of claim 6 wherein the width is about three times greater than the diameter.
- 8. The device of claim 6 wherein the width is about 1.5 cm and the plate has a length of about 3.5 cm.
- 9. The device of claim 1 wherein said gripping portion has a gripping surface with knurling.
- 10. An endosurgical device, comprising:
- a retraction portion having a first end and a second end and a flattened plate between said first and second ends, said first end including an edge for engaging tissue, said flattened plate configured to atraumatically retract tissue;
- a curved shaft having a proximal end and a distal end, said distal end attached to said second end of said retraction portion, said shaft having a first bend subtending a first angle of at least about 120 degrees; and
- a gripping portion attached to said proximal end of said shaft, said gripping portion configured for manually gripping and manipulating the device;
- wherein said plate has a width greater than a diameter of said shaft.
- 11. The device of claim 10 wherein the width is about three times greater than the diameter.
- 12. The device of claim 10 wherein the width is about 1.5 cm and the plate has a length of about 3.5 cm.
- 13. The device of claim 10 wherein said edge and said plate form a third angle, said third angle being in a range of about 90 to 150 degrees.
- 14. The device of claim 13 wherein said third angle is about 135 degrees.
- 15. The device of claim 10 wherein said first angle is about 160 degrees.
- 16. An endosurgical device, comprising:
- a retraction portion having a first end and a second end and a flattened plate between said first and second ends, said first end including an edge for engaging tissue, said flattened plate configured to atraumatically retract tissue;
- a curved shaft having a proximal end and a distal end, said distal end attached to said second end of said retraction portion, said shaft having a first bend subtending a first angle of at least about 120 degrees; and
- a gripping portion attached to said proximal end of said shaft, said gripping portion configured for manually gripping and manipulating the device;
- wherein said proximal end of said shaft includes a second bend forming a second angle between said shaft and said gripping portion of about 110 degrees to position said gripping portion in a direction away from said retraction portion.
- 17. The device of claim 16 wherein said first angle is about 160 degrees.
- 18. The device of claim 16 wherein said plate has a width that is greater than a diameter of said shaft.
- 19. The device of claim 16 wherein said edge and said plate form a third angle, said third angle being in a range of about 90 to 150 degrees.
- 20. The device of claim 16 wherein said gripping portion has a gripping surface with knurling.
