Basic study on vascular dissection with CO2 laser scalpel

Abstract

The advantages of using the laser surgery are in the sharp dissection, prevention from scattering of cancer cells, and so forth. To adopt laser scalpel to vascular surgery and to dissection of the lymph nodes, we have used it in the experimental condition in dog surgery researching for:
1. The influence of the laser scalpel on the vascular flow.
2. The suitable power of it for vascular dissection.
3. Histological change of vascular wall after irradiation.
The conclusions are as follows:
1. Laser scalpel is available on vascular dissection without influence on vascular flow.
2. Suitable condition for vascular dissection was in 10 W 0.07 sec. with pulse wave in power.
3. Histological study revealed that sharp dissection of laser scalpel seems to be favorable to the wound healing.
