Abstract

A bipolar electrosurgical assembly is for use in female pelvic surgical procedures. A first shaft includes a uterine manipulator, a second shaft that fits over the first shaft includes a colpotomy cup and first and second electrodes, and a third shaft can be provided over the second shaft and carries a seal for maintaining pneumoperitoneum. The colpotomy cup uses the first and second electrodes for resecting uterine tissue. Incision and resection may be performed by positioning the colpotomy cup near the cervico-vaginal junction, activating the first electrode, and moving one or both of the electrodes.

Claims (60)

1. A bipolar electrosurgical assembly adapted for insertion into a vaginal cavity for use in female pelvic surgical procedures comprising:

a first shaft, the first shaft having a proximal end, a distal end, and a manipulator adjacent to the distal end of the first shaft; and

a second shaft disposed over the first shaft and having a proximal end, a distal end, a colpotomy cup mounted adjacent to the distal end of the second shaft, a first electrode and a second electrode, an open end of the colpotomy cup having a rim, wherein

a voltage differential is applied between the first and second electrodes to vaporize tissue,

the colpotomy cup has different heights at different points along the rim, and

the first electrode and the second electrode are located along distal edges of the rim.

2. A bipolar electrosurgical assembly adapted for insertion into a vaginal cavity for use in female pelvic surgical procedures comprising:

a first shaft, the first shaft having a proximal end, a distal end, and a manipulator adjacent to the distal end of the first shaft;

a second shaft disposed over the first shaft and having a proximal end, a distal end, a colpotomy cup mounted adjacent to the distal end of the second shaft, a first electrode and a second electrode, an open end of the colpotomy cup having a rim; and

a needle that protrudes from the rim of the colpotomy cup, wherein

the needle is the first electrode,

the second electrode is located along the rim of the colpotomy cup, and

a voltage differential is applied between the first and second electrodes to vaporize tissue.

3. The bipolar electrosurgical assembly according to claim 2 , wherein

the second electrode extends almost entirely around the rim of the colpotomy cup and has first and second ends, and

the needle is disposed on the rim between the first and second ends of the second electrode.

4. The bipolar electrosurgical assembly according to claim 2 , further comprising:

a third shaft disposed over the second shaft and having a proximal end, a distal end, and a seal attached adjacent to the distal end of the third shaft, wherein

the seal is proximate of the colpotomy cup, and

the seal makes a gas-tight seal in the vaginal cavity.

5. The bipolar electrosurgical assembly according to claim 2 , wherein

the second shaft including the colpotomy cup is capable of rotating around the first shaft.

6. The bipolar electrosurgical assembly according to claim 1 , further comprising:

a third shaft disposed over the second shaft and having a proximal end, a distal end, and a seal attached adjacent to the distal end of the third shaft, wherein

the seal is proximate of the colpotomy cup, and

the seal makes a gas-tight seal in the vaginal cavity.

7. The bipolar electrosurgical assembly according to claim 6 , wherein the seal includes a vaginal balloon.

8. The bipolar electrosurgical assembly according to claim 6 , wherein the seal includes a foam plug.

9. The bipolar electrosurgical assembly according to claim 6 , wherein the seal includes malleable discs.

10. The bipolar electrosurgical assembly according to claim 1 , wherein

the second shaft including the colpotomy cup is capable of rotating around the first shaft.

11. The bipolar electrosurgical assembly according to claim 1 , wherein

the first and second electrodes each extend entirely around the rim at the open end of the colpotomy cup.

12. A bipolar electrosurgical assembly adapted for insertion into a vaginal cavity for use in female pelvic surgical procedures comprising:

a first shaft, the first shaft having a proximal end, a distal end, and a manipulator adjacent to the distal end of the first shaft;

a second shaft disposed over the first shaft and having a proximal end, a distal end, a colpotomy cup mounted adjacent to the distal end of the second shaft, a first electrode and a second electrode, an open end of the colpotomy cup having a rim; and

an elongated member extending along the second shaft, the first electrode disposed on the elongated member, wherein

a voltage differential is applied between the first and second electrodes to vaporize tissue.

13. The bipolar electrosurgical assembly of claim 12 , wherein

the elongated member is a spindle that is rotatable around an axis of the second shaft, independently of the colpotomy cup on which the second electrode is disposed.

14. The bipolar electrosurgical assembly according to claim 12 , further comprising:

a third shaft disposed over the second shaft and having a proximal end, a distal end, and a seal attached adjacent to the distal end of the third shaft, wherein

the seal is proximate of the colpotomy cup, and

the seal makes a gas-tight seal in the vaginal cavity.

15. The bipolar electrosurgical assembly according to claim 12 , wherein

the second shaft including the colpotomy cup is capable of rotating around the first shaft.

16. A bipolar electrosurgical assembly adapted for insertion into a vaginal cavity for use in female pelvic surgical procedures comprising:

a first shaft, the first shaft having a proximal end, a distal end, and a manipulator adjacent to the distal end of the first shaft;

a second shaft disposed over the first shaft and having a proximal end, a distal end, a colpotomy cup mounted adjacent to the distal end of the second shaft, a first electrode and a second electrode, an open end of the colpotomy cup having a rim; and

a second cup fixedly mounted to the second shaft, radially inward from the colpotomy cup, wherein

an open end of the second cup has a second rim,

the first electrode is located along the rim of the colpotomy cup,

the colpotomy cup is rotatable independently of the second cup, and

a voltage differential is applied between the first and second electrodes to vaporize tissue.

17. The bipolar electrosurgical assembly according to claim 16 , further comprising:

a third shaft disposed over the second shaft and having a proximal end, a distal end, and a seal attached adjacent to the distal end of the third shaft, wherein

the seal is proximate of the colpotomy cup, and

the seal makes a gas-tight seal in the vaginal cavity.

18. The bipolar electrosurgical assembly according to claim 16 , wherein

the second shaft including the colpotomy cup is capable of rotating around the first shaft.
