Abstract

A system for removal of a tissue specimen from an internal body cavity includes a cannula arrangement having an access cannula including a first elongated tubular member, a deployment cannula including a second elongated tubular member configured for insertion into the first lumen, a deployment plunger including a proximal base and a plurality of engagement arms extending distally from the proximal base, and an inner cannula including a third elongated tubular member. The system further includes a containment bag selectively deployable from the cannula arrangement. Distal advancement of the deployment cannula relative to the access cannula deploys a first portion of the containment bag from the cannula arrangement, and distal advancement of the deployment plunger relative to the deployment cannula and the access cannula deploys a second portion of the containment bag from the cannula arrangement.

Claims

1. A method of containing a tissue specimen disposed within an internal body cavity, comprising:

inserting a cannula arrangement through a vagina and into a pelvic cavity, wherein the cannula arrangement includes an access cannula, a deployment cannula slidably disposed within the access cannula, a deployment plunger having a plurality of engagement arms slidably disposed within a first annular space defined between the access cannula and the deployment cannula, and an inner cannula slidably disposed within the deployment cannula, and wherein a containment bag is disposed within the cannula arrangement;

distally advancing the deployment cannula relative to the access cannula to deploy a first portion of the containment bag from the cannula arrangement, in the pelvic cavity, and at least partially about a tissue specimen; and

distally advancing the deployment plunger relative to the deployment cannula and the access cannula to deploy a second portion of the containment bag from the cannula arrangement and into the pelvic cavity such that the containment bag is further disposed about the tissue specimen.

2. The method according to claim 1, further comprising:

proximally withdrawing the inner cannula from the deployment cannula; and

reinserting the inner cannula distally through the deployment cannula to deploy a third portion of the containment bag from the cannula arrangement and into the pelvic cavity.

3. The method according to claim 1, further comprising withdrawing the first portion of the containment bag from the pelvic cavity through an abdominal port.

4. The method according to claim 1, further comprising:

inserting a tenaculum or a grasper through the inner cannula; and

grasping the specimen with the tenaculum or grasper to maintain the specimen in position or pull the specimen proximally during deployment of at least one of the first or second portions of the containment bag.

5. The method according to claim 1, further comprising:

proximally withdrawing the inner cannula; and

inserting a morcellator through the deployment cannula and into the pelvic cavity within the containment bag.

6. The method according to claim 5, wherein an insert portion of the deployment cannula is replaced with a different insert portion after proximally withdrawing the inner cannula and before inserting the morcellator.
