General Surgery

The first Espiner sac was introduced in 1990 and designed to accommodate the largest inflamed gall bladder that might be encountered. This was the 100 size.

The 70 size was originally designed to capture a grossly inflamed appendix or a normal sized gallbladder.

Advances in surgical technique have led to a demand for a sac deployable via a 5 mm trocar; we have achieved this for removal of a normal sized gall bladder or an inflamed appendix.

The ECO and Master E-sacs now offer safe capture and secure extraction for the complete range of laparoscopic surgery as indicated below.
