Development and Efficacy Testing of Variable Pressure Flat Ultrathin Water Jet Device for Debridement and Dissection

Debridement and dissection are most important aspects of surgery. Most of the chronic non-healing ulcers are covered with necrotic materials and bio-films making them complicated to manage. Current practice is surgically removing the necrotic materials from the wounds using scalpel blades and scissors. The major complications of this procedure are significant amount of blood loss, time consuming, loss of healthy granulation tissues and remaining of residual sloughs in between clefts of the wounds. These lead to repetition of the procedure and delayed wound healing. To overcome these challenges we propose a variable pressure flat ultrathin water jet which will effectively remove the necrotic and dead tissues while preserve the healthy tissue and minimize the amount of blood loss during debridement. Variable pressure flat ultrathin water jet had never been tried before for debridement and dissection. Water jet can be effectively applied to the clefts of the wounds leading to complete removal of slough. Mostly the procedure can be completed very quickly with no requirement of anesthesia at all. Again the water jet debridement procedure can be repeated daily with minimum morbidity till healthy granulation tissue appears. Variable pressure flat ultrathin water jet can be effectively used for dissection. Optimum water jet pressure with precise dimension can effectively divide the intervening fat and loose areolar tissue leading to separation and visualization of vital structures during difficult surgeries such as axillary dissection and pancreatic necrosectomy. This method will avoid the potentially dangerous complications of sharp dissection using scissors or diathermy. The variable pressure flat ultrathin water jet will reduce the dissection time and aid in proper identification of different structures with minimum complications.
