Abstract:Surgical cutting is a fundamental aspect of modern medicine. The problems in conventional surgical cutting indicate that improving surgical cutting methods is crucial for enhancing patient outcomes, reducing the risk of complications, and enabling more complex surgical procedures. A clinical adaptation of the technique of water jet cutting is now posed as possible improvement because it does not inflict thermal damage and promises selective tissue cutting. The objective of this research was to design, build and test a new compact prototype of a pulsed water jet device for clinical surgery. A compact functioning prototype was successfully developed and tested. The device is straight forward to operate and could achieve required parameters levels as specified in the list of requirements. Also input parameter settings can be used to accurately and reliably control cutting power and cutting depth within a tissue phantom. We could show that short pulses reduce water usage while retaining cutting power, reducing the problem of excess water. Although further research should prove the tissue selectivity of the technology, this study provides evidence that pulsed water jet technology can be used in a clinical setting to dissect soft tissues.
