Robotic Surgical System - Enabling Minimally Invasive Microsurgery


Computer Motion's ZEUSª Robotic Surgical System incorporates the Company's proprietary computer, robotic, force feedback and speech recognition technologies to fundamentally improve surgeon dexterity and precision in complex minimally invasive surgery procedures. Additionally, ZEUSª will enable a new class of minimally invasive microsurgery procedures that are presently not possible using conventional minimally invasive surgical technology.


ZEUSª is comprised of three interactive robotic arms placed at the operating table, a dedicated computer controller and an ergonomically enhanced surgeon console. One robotic arm positions the endoscope while the other two robotic arms manipulate surgical instruments under the direct control of the surgeon. While seated at the console, the surgeon views the operative site with a high resolution monitor and operates handles which resemble conventional surgical instruments. With voice commands, the surgeon controls the movements of the endoscope and changes the view of the video monitor. The surgeon's hand movements are scaled and hand tremor is filtered through the computer and translated via the robotic arms into precise micro movements at the operative site. For example, the surgeon might move the surgical instrument handle at the console one inch while the corresponding robotic instrument tip at the operative site moves only one-tenth of an inch. In this operating environment, the surgeon is comfortable, ergonomically positioned and able to perform complex, minimally invasive microsurgical procedures with greater precision.


Computer Motion believes ZEUSª will enable fully endoscopic heart bypass surgery. This type of surgery is called endoscopic coronary artery bypass grafting (E-CABGª) and takes place through ports the diameter of a pencil. As a result, these new minimally invasive surgery procedures will result in significant benefits for patients: decreased pain and trauma, shorter hospital stays and convalescent periods and lessened cosmetic concerns. Furthermore, an increase in minimally invasive procedures will result in lower overall healthcare costs.


The Advantages of ZEUSª


Improved precision by enabling a surgeon to scale his/her hand movements to a microsurgical scale; Improved anatomical access to confined areas through incisions smaller that the diameter of a pencil; Improved dexterity with robotic manipulation of surgical instruments. Elimination of hand tremor; Enhanced tactile feedback with amplifies a surgeon's sense of touch while grasping delicate tissue; Enhanced visualization with a steady operative field of view; and Minimized surgeon fatigue with a comfortable, ergonomic operating environment.
