Embodiment Construction

[0051]To reduce the time and money associated with removal of large tissue samples, new systems and methods of large volume tissue removal have been created. Using the new system and method has the added benefit of containing the sample in the bag, reducing the risk of seeding cancer cells into unaffected tissue due to uncontrolled fragmentation that occurs during shredding or other tissue reduction practices possibility. In addition, there is an increased likelihood of performing minimally invasive surgical approaches with smaller incisions in surgery where cancer is suspected. Since the systems and methods described herein include minimally invasive procedures, recovery time from using such systems and methods is reduced.

[0052] The new system also has the advantage of allowing pathologists to subsequently "reassemble" tissue segments. This is due to the more controlled cutting of tissue compared to methods used today. This can be further aided by the use of colorants o...

Abstract

A tissue removal system for extracting a tissue sample from a patient is disclosed. The system has a retrieval bag, a first electrode and a return electrode. The retrieval bag has a flexible container with an opening. A first electrode is connected to the interior of the flexible container and has a wire having an exposed area, a first load bearing area, a coating having a first active electrode surface area, and an impedance greater than that of the wire. The first active electrode surface area is smaller than the exposed area. The coating is configured to degrade during application of electrosurgical power, and wherein the degradation enlarges the first active electrode surface area during application of electrosurgical power.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims U.S. Provisional Application No. 62 / 027,645, filed July 22, 2014, entitled "LARGE VOLUME TISSUE REDUCTIONAND REMOVAL SYSTEM AND METHOD," and filed January 19, 2015, entitled "LARGE VOLUME TISSUE REDUCTION AND REMOVAL SYSTEM AND METHOD" has priority to US Provisional Application No. 62 / 104,969, the entire disclosure of which is incorporated herein by reference for all appropriate purposes as if fully set forth herein. technical field [0003] The present invention relates to surgical devices. Specifically, but not by way of limitation, the present invention relates to bulk tissue removal. Background technique [0004] Existing methods of removing large tissue samples with minimally invasive procedures such as, but not limited to, hysterectomy, nephrectomy, and splenectomy are to manually reduce tissue size using a morcellator or by means of RF energy, mechanical cutting, or rupture methods . Th...
