The present invention pertains to surgical medical equipment sector, and more particularly to bags of removal of surgical specimens. The main object of the present invention is a device of removal of surgical specimens intended to isolate, contain and remove body tissue inside the body, as part of a minimally invasive surgical procedure so as to optimize the process by reducing the volume of the parts surgical, increasing its consistency and molding them with an elongated shape by a mechanism insufflation, and generally also subsequent removal of the fluid gas or liquid, applied to corresponding sub-chambers of an intermediate chamber bag double container layer part surgical. BACKGROUND OF THE INVENTION

Laparoscopic and endoscopic surgical procedures are minimally invasive procedures in which operations are performed within the body by means of elongated instruments inserted through narrow inlet ports formed in the body. The initial opening in the body tissue to allow passage of the endoscopic or laparoscopic instruments to the interior of the body may be a natural passageway of the body, or can be created by a tissue piercing instrument such as a trocar. Laparoscopic and endoscopic procedures generally require that any instrumentation inserted into the body be sealed, ie must be taken to ensure they do not enter or exit gases from the body through the instrument of the entrance incision so that it can be blown the surgical region of the body, for example, the abdominal cavity.

Mechanical actuation of such instruments is for the most part limited to the movement of the various components along a longitudinal je with means provided to convert longitudinal movement to lateral movement where necessary. As endoscopic tubes or laparoscopic instrumentation, and any punctures or incisions required are elativamente narrow, endoscopic or laparoscopic surgery is less invasive and causes much less trauma to the patient as compared to procedures in which required the surgeon to make large incisions .

Minimally invasive procedures are often used to remove all or part body tissue or organs within the body. during such

C0NFIRMATI0N C0PY procedures, it is common that an affected tissue or organ are to be removed from the access opening made in the skin or through a cannula. To prevent infectious contamination or spread oncological, it insulates the surgical specimen from the abdominal wall, chest etc. at the time of extraction. For this purpose they are used extraction elements which isolate the part and prevent contact with other tissues in the output path.
