A Multi-Point of View 3D Camera System for Minimally Invasive Surgery

摘要

As a result of the rapid spreading of stereoscopy in the consumer market, three-dimensional (3D) vision systems are replacing two-dimensional devices. A fast growing technology in the 3D visualization systems market is multi-views autostereoscopic displays (ADs). However, these devices have not found yet direct application in minimally invasive surgery (MIS), mainly because of the encumbrance of the acquisition system. Indeed, at least five aligned camera modules must be embedded in a device insertable through a laparoscopic trocar. The aim of this work is the development of a miniaturized acquisition system for MIS, which can be interfaced with multi-views ADs, thus paving the way to the use of such devices in surgery. The device dimensions are compatible with MIS access ports and a magnetic link allows the user to anchor and move the acquisition system inside the abdomen.
