| Research Abstract |
Energy devices are useful for performing angiotomy during surgery. However, energy devices cannot be used to incise vessels of all sizes. We conducted a basic study of upgrades in energy devices. We experimented with a new way of incising vessels by rolling additional material around the vessels, which improved the pressure resistance of the stump as well as incision speed. We tested the effects of several additional materials on angiotomy performed with energy devices. We measured the incision time and burst pressure. Moreover, we examined the fusion distance and change of stump microscopically. In the result, oxidized cellulose sheet significantly reduced the time taken to incise vessels. The other materials tended to do. There was no significant difference between groups with respect to the burst pressure and fusion distance of stump. This study provided the possibility that additional materials enabled to reduce the time to incise vessels without decreasing the burst pressure.
