There is an appropriate sac for all the urological operations which require tissue extraction. For those who need it, the ECO and Master E-sacs can be introduced more than once in the same operation.

Lymph nodes can be securely captured using either the 50ECO-R or 110ECO-R.  ECO-sacs of 70 and 100 size will capture most prostates.  The 100INS has an elongated tail which protrudes through the trocar after capture; drawing the sac tail into the trocar closes the sac mouth, and by withdrawing the sac tail and trocar together the specimen is removed.

We have redesigned the automatic 112 WG for specific use in prostatectomy. The sac shape has been modified to accommodate any size of tumour and to allow full tight closure of the mouth into the 12 mm trocar for removal by pulling on the drawstring.

Working with surgeons in robotic surgery we have quickly realised the advantage of being able to offer a large capacity sac deployable via a 12 mm trocar; our 230 size has a capacity of 3100 ml in the ECO range and our 160 size has a capacity of 1500 ml in the Master e-sac format.
