Introduction

The present patent describes a surgical instrument for collecting tissues during endoscopic surgery. The instrument offers two functional areas: a disposable bag and a reusable clamp. It is characterized by its efficiency, low cost of implementation and simplicity of use, when compared to the more traditional, complicated, mono-use and often expensive  surgical instruments.

Technical features

The current devices on the market have been designed for application in laparoscopic surgery and over the years have also found use in other minimally invasive surgical branches that involve small skin accesses. In minimally invasive thoracic surgery, for example, it is not necessary to use such complex biological sample recovery systems that currently we are using tools that have been designed for other needs and that are adapted, albeit effectively, in other specialist branches. Furthermore, these instruments cannot be reused during the same surgery. The present invention has been conceived to be used in minimally invasive surgical procedures which require smaller retrieval instruments and which can be reused several times during the same surgery.

The Forceps are specifically designed to insert, open, securely close and remove the tissue Retrieval Bag. The Retrieval Bag is tough, made of tear resistant, fluid resistant material. Especially stable, it’s transparent to allow visibility of the collected tissue samples. The bag’s tapered design prevent tissue bunching and its repeated use in the same procedure, whilst the its prismatic structure encourages automatic bag closure.  The Retrieval Bag is inserted and removed with specially designed  modular system that adapts to the nozzles of any forceps, thus eliminating the need for disposable and expensive insertion apparatus. Thanks to the patented shape, fabric fragments and liquids are pushed into the container space during extraction, thus avoiding the incision enlargement.
