Like the ECO-sac, the Master E-sac has a drawstring function, but in addition has removable plastic arms to keep the mouth of the sac open. It comes in a wide range of sizes that cover most needs of excisional laparoscopic surgery.
There are three components: a valved cannula, a delivery rod and the sac with a tail and a drawstring:
- The valved cannula comes in two sizes: 10mm and 12mm.
- The delivery system consists of a rod with two flexible arms and a pull-ring.
- The sac includes a security tail which locks into the pull ring of the rod for easy loading and a sleeve on the mouth to house the flexible arms which keep the mouth of the sac open in use; a separate sleeve houses the drawstring.
In use, the sac is loaded into the cannula by pulling the ring on the rod until all the sac is contained in the cannula. Pushing the rod fully home against the valve block deploys the sac completely with the mouth fully open.
