Abstract

Laser is an integral part of diagnostics and therapy in modern medicine. However, removing hard tissue with laser became successful only recently. The advantages of laser osteotomy are high precision and complete freedom in designing the cutting geometry. Nevertheless, these can be fully realized only when the laser system is guided by a robot. The most important challenges here are the miniaturization and the ergonomic design of the entire system.
In this dissertation, I presented our first experience with a computer-assisted, integrated and miniaturized laser system, which is driven by a surgical robot. An Er:YAG laser source was integrated into a housing with an optical system and attached to the surgical robot arm. Pre-operatively generated planning data was imported and used to execute the osteotomies. Intraoperatively, a navigation system performed the positioning. In the actual operation room environment, the laser osteotome was used to produce different defect geometries in the mandibular bones of six minipigs. On the contralateral side of the mandible, surgeons used a PZE osteotome to create the same defects for comparison. The performance of the laser osteotome was analyzed in terms of the workflow, ergonomics, bone healing, user-friendliness, and safety. We were able to demonstrate that the laser osteotome could be ergonomically integrated into the operation room environment. It showed a high precision and the complex cutting geometries were transferred as planned. We expect that the computer-assisted and robot-guided laser osteotome will routinely used in the future, whenever special incision and high precision are required in osteotomies.
