Abstract

As part of our computer assisted surgical techniques (CAST) program, we use computers to assist in the guidance of surgical lasers. The computer helps to create laser incisions with minimal widths, a reduction of collateral thermal damage, and regulates the rate of tissue ablation. Previous studies have compared laser incisions under manual control to incisions made with the CAST system. These studies were carried out with healthy animals. In this study, we compare the manual and CAST laser incisions on rats with induced diabetes. The diabetic rats have impaired wound healing and make a better model for our wound healing studies. Cutaneous incisions were made on the dorsal pelt using a carbon dioxide laser. The incisions were sutured and allowed to heal for 3, 7, 14, and 21 days. Wounds were analyzed histologically and with tensiometry. We have found definite advantages to the CAST program.
