Hemostasis by means of a cautery knife equipped with an air spray for burns over a large area

In operations in which debridement is performed over a large area (e.g., surgery for whole-body burns), it is necessary to keep the length of the operation short and the amount of blood loss as small as possible to minimize stress to the patientʹs body. In this study, we developed a cautery knife to which an air spray is attached for surgical procedures in which debridement is performed as treatment for burns over a large area. We have demonstrated herein that this device is very effective for reducing both blood loss and the duration of surgery as well as for simplifying the achievement of hemostasis.
