Abstract

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

Claims20

Dependent claims

A system for removing a tissue specimen through a body opening defining a tissue margin, the system comprising:

a guard including a band made of flexible cut-resistant material;
the band having an inner surface and an outer surface interconnected by a top end and a bottom end and by a first end and a second end;
the band being configured to define a central lumen having a longitudinal axis;
the central lumen having a lumen diameter that is perpendicular to the longitudinal axis;
the outer surface of the band having a concavity along the longitudinal axis from the top end to the bottom end and extending circumferentially around the guard from the first end to the second end;
wherein at least a portion of the outer surface of the band overlaps and faces at least a portion of the inner surface of the band such that the inner surface of one part of the band is nested in the concavity of the outer surface of the band.
