ABSTRACT

Introduction: To present the physical and functional characteristics of the first robotic arm to hold and place laparoscopes designed and built in the Bioelectronic Department in the Centro de Investigación y Estudios Avanzados del Instituto Politécnico Nacional (Cinvestav del IPN) in Mexico City. Method: In 2 years (1998-2000), we built a robotic arm with 5o of freedom to hold laparoscopes of 10 mm of diameter with three softwares to manipulate laparoscope with ocular motion, voice recognition, and physical control manual. Results: We built a robotic arm of 5o of freedom to hold and place 10-mm laparoscopes and three navigation programs developed to operate robotic arm. We think the navigation systems created and controlled by head motions (optoelectronic) and by the voice processing are unique, fast, easy, and more precise because the surgeon controls the laparoscope automatically with his/her head without the need of prior analysis of laparoscope position, but with the disadvantage of requiring greater concentration and immobility, and therefore discomfort and seeing that motion of the scope would be out of the operating field. We can operate these interphases simultaneously or alternately and adjust in accordance with the surgeon’s skill. It is possible to use the robotic arm in the following surgical fields: laparoscopic surgery; thoracoscopy, cardiovascular laparoscopic surgery, and arthroscopy. The manipulator is flexible, the surgeon can choose the interphase, this system could be teleoperated by Internet, intranet, satellite, telephones, and internet 2. The authors describe original, innovative, and unique ideas. Discussion: We think to demonstrate the feasibility to control the laparoscopes with diferents programs (softwares) with a robotic arm of five degrees of freedom. We considere that with these results in a nearly future we could perform laparoscopics surgeries in experimental animals and then in the human patients.
