Development of a new method and device for securing haemostasis during transoral surgery: in vitro and cadaver experiments

Abstract

The objective of this study is to present cadaver and model experiments of an instrument and technique that may overcome the problems of achieving hemostasis after tonsillectomy and surgery of the tongue base. The safety and the reduced need for microclips in surgeries in these areas can be accomplished by introducing the “ligature” device, which makes it possible to pass a suture under a blood vessel or other diffuse areas of bleeding with a single movement. This technique may also be applied to operations on the supraglottic larynx, oropharynx and hypopharynx. Utilization in the larynx may be more limited. This new instrument and technique for the ligature device has the potential to be applied successfully in other fields of surgery. The main advantages of this technique are its simplicity and safety.
