Abstract

A specimen retrieval device includes a tubular body defining a longitudinal bore, an articulation shaft disposed within the longitudinal bore of the tubular body, and a specimen receptacle affixed to a support mechanism at the distal portion of the tubular body. In embodiments, the specimen receptacle has two openings which may be used to transfer a tissue specimen from within a patient's body cavity to outside of the patient's body.

First claim

What is claimed is:

1. A method comprising:
introducing a tubular body of a specimen retrieval device having a proximal portion and a distal portion through a body opening into a body cavity;
introducing an articulation shaft having a proximal portion, a distal portion, and an articulation knob through a longitudinal bore of the tubular body such that the distal portion of the articulation shaft is coupled to a support member that is pivotably supported about a pivot axis on the distal portion of the tubular body;
positioning the distal portion of the tubular body within the body cavity to position a specimen receptacle supported on the support member in the body cavity;
actuating the articulation knob of the articulation shaft to articulate the support member about the pivot axis to reposition a first opening of the specimen receptacle in relation to a tissue specimen from a non-articulated position to an articulated position;
removing a second opening of the specimen receptacle from the body cavity;
passing the tissue specimen through the first opening of the specimen receptacle with the first opening in the articulated position into the specimen receptacle and out the second opening; and
removing the specimen retrieval device from the body cavity.

2. The method of claim 1 , wherein introducing the specimen retrieval device through the body opening occurs by passing the distal portion of the tubular body through a cannula.

3. The method of claim 1 , wherein actuating the articulation knob includes rotating a threaded portion of the articulation shaft within a threaded portion of the longitudinal bore to longitudinally move the articulation shaft, thereby articulating the support member.

4. The method of claim 1 , wherein removing the second opening from the body cavity occurs by grasping the specimen receptacle with a grasping device and pulling the second opening out of the body cavity.

5. The method of claim 4 , wherein the grasping device is selected from the group consisting of a forceps, a tenaculum, and combinations thereof.

6. The method of claim 4 , wherein removing the second opening occurs by pulling the second opening out of a cannula.

7. The method of claim 4 , wherein removing the second opening occurs by pulling the second opening out of a patient's vagina.

8. The method of claim 1 , wherein the support member includes a pair of resilient fingers which support the specimen receptacle and open the first opening of the specimen receptacle in a deployed state.

9. The method of claim 8 , wherein passing the tissue specimen through the first opening of the specimen receptacle into the specimen receptacle and out the second opening occurs by utilizing a grasping device to grasp the tissue specimen and pass the tissue specimen through the specimen receptacle.

10. The method of claim 9 , wherein the grasping device is selected from the group consisting of a forceps, a tenaculum, and combinations thereof.

11. A method of performing a laparoscopic hysterectomy procedure comprising:
introducing a tubular body of a specimen retrieval device having a proximal portion and a distal portion through a body opening of a patient;
positioning the distal portion of the tubular body within a pelvic cavity of the patient;
deploying a support member of the specimen retrieval device from the tubular body into the pelvic cavity of the patient to deploy a specimen receptacle having a first opening and a second opening into the body cavity of the patient;
moving the support member from a non-articulated position to an articulated position to move the first opening of the specimen receptacle to an articulated position;
withdrawing a portion of the specimen receptacle defining the second opening from the pelvic cavity of the patient through a vaginal opening of the patient;
passing a tissue specimen through the first opening of the specimen receptacle into the specimen receptacle with the first opening of the specimen receptacle in the articulated position; and
removing the tissue specimen from the specimen receptacle through the second opening of the specimen receptacle and the vaginal opening of the patient; and
removing the specimen retrieval device from the pelvic cavity.

12. The method of claim 11 , wherein withdrawing the portion of the specimen receptacle defining the second opening from the pelvic cavity of the patient through the vaginal opening of the patient occurs by grasping the specimen receptacle with a grasping device and pulling the second opening out of the vaginal opening.

13. The method of claim 12 , wherein the grasping device is selected from the group consisting of a forceps, a tenaculum, and combinations thereof.

14. The method of claim 11 , wherein passing the tissue specimen through the first opening of the specimen receptacle into the specimen receptacle and out the second opening occurs by utilizing a grasping device to grasp the tissue specimen and pass the tissue specimen through the specimen receptacle.

15. The method of claim 14 , wherein the grasping device is selected from the group consisting of a forceps, a tenaculum, and combinations thereof.
