Waterjet Surgery –A Sparing Oper ative Procedure.Biological tissue such as organs, connective tissue, vessels or nerves can have very differentcellular structures. Waterjet surgery, a new form of dissection which has beensuccessfully used since several years, separates the different tissue types with theirvarying elasticity and firmness, with the help of precisely adjusted water pressure. Thekinetic energy of the waterjet carefully separates the layers of tissue.In hepatic surgery, for example, the procedure selectively differentiates between liverparenchyma, blood vessels and bile ducts. Soft parenchymal tissue is washed out, whilethe network of blood vessels is preserved and can be subsequently treated with littleloss of blood. The operative time is reduced. In urology the selectivity of the waterjetis used to dissect the prostate from its surrounding tissue. Due to the physical propertiesof biological tissue the jet dissects precisely and anatomically along the marginsbetween the different tissue structures.The advantages of the waterjet procedure which range from tissue selectivity tominimal blood loss open up many different areas of application in almost all surgicalspecialties (cf. pages 4 and 5).Advantages of waterjet surgeryat a glanceShorter operating timesSpares blood vessels, nerves and organsMinimized bleeding, controlled managementof bleedingSelectivityBlood vessels and nerves are preserved due to predefined water pressures,while the surrounding tissue is selectively dissected (example taken fromhepatic surgery).High degree of tissue selectivity duringpreparation and dissection of tissue layersPrecise and intact margins along the lineof dissection, no necrosis of the marginsGood visibility at the operative site due tointegrated irrigation and suctionExpansion effectSeparation of tissue layers, e.g. in radical prostatectomies.2
ERBEJET ® 2 – The New Systems Concept.A powerful team – The waterjet and the electrosurgicalworkstationThe ERBEJET 2 was developed to be compatiblewith the ERBE VIO, with respect to both its sizeand functionality. It can be utilized either as amodule of the VIO system or as an autonomousunit on a cart or on suspension arm system tosave space in the operating room. A combinationof the two surgical procedures bothelectrosurgery and waterjet surgery offers thefollowing advantagesShorter operating times as no change ofinstruments is requiredBoth systems can be accommodated withina very small spaceTransfer of data via the ECB(ERBE Communication Bus)Simple operation via the displayThe ERBEJET 2 has an easy-to-operateuser interface. The parameters can beadjusted according to the individualindications and saved in 9 differentprogram settings. The impact of thewaterjet is avail able as finely adjustablesteps which create reproducibledissection results. And the setting caneven be altered during activation.The interface of the ERBEJET 2 is alsoused to enter the settings for thesuction module ESM 2.The pump unit of the ERBEJET 2 allowscontinuous application of thewaterjet.Separating mediumThe separating medium is a sterilesaline solution. It is connected to thesystem in the form of standard infusioncontainers.Activation is carried out via the footswitch with the ReMode function,which allows the unit settings to becontrolled straight from the operatingtable.ESM 2 Suction moduleThe type of activation and the degreeof suction of the ESM 2 are adjustedvia the interface of the ERBEJET 2.Activation occurs either simultaneousto the application of the waterjet oris switched on as required using thefoot switch. The suction pump can beprogrammed to continue running fora certain time after waterjet is no longeractivated. This ensures a good visibilityat the operative site even afterthe waterjet has been deactivated.3
