Method of tissue morcellation using an ultrasonic surgical instrument with a ballistic specimen bag

Abstract

With the advent of laparoscopic and endoscopic surgery, the patient is benefiting from shorter hospitalization, less pain, and generally better outcomes. However, the minimization of the size of incision a surgeon uses in these procedures has created some unique challenges. Large tissue masses, such as fibroid tissue masses, are traditionally excised during the surgical procedure and removed intact from the patient through the surgical incision. One common procedure for reducing the size of large tissue masses is generally referred to as morcellation. In the present invention, a method of morcellating tissue is described that includes the steps of: inserting a ballistic specimen bag through a cannula; opening the ballistic specimen bag; inserting tissue into the ballistic specimen bag; closing the ballistic specimen bag around a ultrasonic surgical instrument; and cutting or debulking the tissue with the ultrasonic surgical instrument. The present invention is further directed to a method as described above wherein the specimen bag is constructed of a ballistic material having a V.sub.50 attribute greater than or equal to 1225 feet per second. The present invention is also directed to a method as described above wherein the ballistic specimen bag is coated or impregnated with a sealant material such as silicone.
