Abstract

A method of amputating and morcellating a uterus (10) includes introducing a first tissue bag (1) into the abdomen of the patient, and placing the first tissue bag over the uterus. A laparoscopic surgical instrument (11) is introduced into the first tissue bag, and the uterus (10) is amputated using the laparoscopic surgical instrument. The first tissue bag (1) is closed around the amputated uterus, and the first tissue bag containing the amputated uterus is placed into a second tissue bag (20). A morcellating instrument is introduced into the second tissue bag (20) and the uterus is morcellated within the second tissue bag. Once the uterus (10) has been morcellated, the second tissue bag (20) containing the morcellated uterus is removed from the abdomen of the patient.

First claim

What is claimed is:

1. A method of amputating and morcellating a uterus of a patient, the method comprising:
(i) introducing a first tissue bag into the abdomen of the patient,
(ii) placing the first tissue bag over the uterus,
(iii) introducing a laparoscopic surgical instrument into the first tissue bag,
(iv) amputating the uterus using the laparoscopic surgical instrument,
(v) closing the first tissue bag around the amputated uterus,
(vi) placing the first tissue bag containing the amputated uterus into a second tissue bag,
(vii) introducing a morcellating instrument into the second tissue bag,
(vii) morcellating the uterus within the second tissue bag, and
(viii) removing the second tissue bag containing the morcellated uterus from the abdomen of the patient.

2. The method according to claim 1 , wherein the laparoscopic surgical instrument is a snare device.

3. The method according to claim 2 , wherein the snare device is an electrosurgical snare.

4. The method according to claim 1 , wherein the step of introducing a laparoscopic instrument into the first tissue bag comprises introducing the instrument through an aperture in the side of the first tissue bag.

5. The method according to claim 1 , wherein the morcellating instrument is an electrosurgical morcellator.

6. The method according to claim 1 , wherein the morcellating of the uterus includes removing the first tissue bag from the second tissue bag prior to morcellating the uterus.

7. The method according to claim 1 , wherein the morcellating of the uterus includes morcellating the first tissue bag along with the uterus.

8. The method according to claim 1 , wherein the morcellating of the uterus includes insufflating the second tissue bag.

9. The method according to claim 8 , wherein the morcellating of the uterus includes:
(i) pulling the second tissue bag partly through though an incision in the patient, such that a portion of the first tissue bag including an opening for access to an internal enclosure of the tissue bag and the aperture are outside the patient,
(ii) insufflating the second tissue bag with an insufflation gas, and
(iii) morcellating the uterus within the second tissue bag using the morcellating instrument.

10. The method according to claim 1 , wherein the first tissue bag includes an internal enclosure with an opening allowing access to the enclosure.

11. The method according to claim 10 , wherein the first tissue bag further includes a semi-rigid ring around the opening to ensure that the first tissue bag assumes an expanded shape once the first tissue bag has been deployed within a body of a patient.

12. The method according to claim 10 , wherein the first tissue bag includes a transparent wall forming the internal enclosure.

13. The method according to claim 12 , wherein the first tissue bag further includes a drawstring that is located in the wall at a position spaced from the opening so as to define a neck portion of the first tissue bag.

14. The method according to claim 13 , wherein the first tissue bag further includes an instrument aperture within the neck portion which is located between the opening and the drawstring.

15. A method of amputating and morcellating a uterus of a patient, the method comprising:
(i) introducing a first tissue bag into an incision made in an abdomen of the patient, the first tissue bag including an internal enclosure with an opening that allows access to the enclosure,
(ii) placing the first tissue bag over the uterus so that the uterus is located within the internal enclosure,
(iii) introducing a laparoscopic surgical instrument into the first tissue bag through an instrument aperture located within a neck portion of the first tissue bag,
(iv) amputating the uterus using the laparoscopic surgical instrument,
(v) closing the first tissue bag around the amputated uterus using a drawstring located in the neck portion of the first tissue bag,
(vi) introducing a second tissue bag into the abdomen of the patient, and placing the first tissue bag containing the amputated uterus into the second tissue bag,
(vii) introducing a morcellating instrument into the second tissue bag,
(vii) morcellating the uterus within the second tissue bag, and
(viii) removing the second tissue bag containing the morcellated uterus from the abdomen of the patient.

16. The method according to claim 15 , wherein the laparoscopic surgical instrument is a snare device.

17. The method according to claim 16 , wherein the snare device is an electrosurgical snare.

18. The method according to claim 15 , wherein the morcellating instrument is an electrosurgical morcellator.

19. The method according to claim 15 , wherein the morcellating of the uterus includes removing the first tissue bag from the second tissue bag prior to morcellating the uterus.

20. The method according to claim 15 , wherein the morcellating of the uterus includes morcellating the first tissue bag along with the uterus.
