Biomedical engineering R&D picks up

Article Abstract:

Biomedical engineering is experiencing advances in the understanding of magnetic fields in biological systems, micromachining, the use of computer imaging, and integrated diagnostic/therapeutic devices for improved care delivery. An improved understanding of the effects of magnetic fields on the central nervous system combined with advances in room-temperature superconductors may lead to new classes of therapeutic and diagnostic devices. The Food and Drug Administration has approved a nitroprusside infusion controller that automatically monitors blood pressure and delivers the appropriate amount of drug to control it. Integrated circuit fabrication technology will be used to micromachine microscale mechanical systems for such applications as cutters to remove obstructions in diseased arteries. Use of imaging systems for surgery is also discussed.

Expert opinion: imaging and robotics are changing the face of surgery

Article Abstract:

Technological advances in endoscopic surgery are often preceded by an innovation in imaging technology. The invention of the computer three-chip video camera enables assistants to share the viewing of an operation in progress. Medical visualization systems are comprised of an endoscope, camera, light source and adaptors integrated by an equipment distributor and then sold to the end user. Three dimensional video enables the endoscopic surgeon to have depth perception thus increasing safety and reducing operating time. The surgeon's sense of touch, that is not possible to use with endoscopic operations, may be compensated for by intraoperative ultrasound imaging in the future. Robotics are used as an extension of stereotaxic surgery to precisely position instruments by means of a mechanical reference system.
