Abstract:
1. A simulation system for arthroscopic surgery training, wherein a surgical procedure is simulated by a user of the system the system comprising: at least one data processing unit; one or more simulated arthroscopic instruments; a simulated arthroscopic camera; a working platform provided with at least one platform guide; a human anatomy model arranged on the working platform and representing a joint on which the surgical procedure is being simulated in real size, said human anatomy model being provided with a plurality of openings corresponding to arthroscopic portals through which the user inserts the simulated arthroscopic instrument into the joint during the simulated surgical procedure; at least two working devices arranged in the working platform around the human anatomy model, each being provided with at least one mobile member, the end of which is provided with an instrument guide for guiding one of the simulated arthroscopic instruments that is inserted into one of the arthroscopic portals during the simulated surgical procedure; and a monitor to present images sent by the at least one data processing unit in relation to the simulated surgical procedure, wherein at least one of the simulated arthroscopic instruments used during the simulated surgical procedure being fixed to one of the mobile members of the working devices; wherein the simulated arthroscopic camera is fixed to one of the mobile members of the working devices; and wherein the at least one data processing unit is configured: to acquire and to process a first group of data relating to the position of the arthroscopic portals, and to extract from said first group of data a first group of position coordinates of said arthroscopic portals; to acquire and to process a second group of data relating to the position and orientation of the mobile members of the working devices, and to extract from said second group of data a second group of position coordinates and direction vectors of each of the arthroscopic instruments used during the simulated surgical procedure; and to process the information received and to send information to the monitor in real time, in the form of images representing simulated view of the internal anatomy of the joint and of the one or more instruments inserted therein, which is obtained from the arthroscopic camera depending on the position and orientation of the latter inside the joint, as would be seen in a real operation, wherein the working devices move on the at least one platform guide to facilitate access of the instrument to the arthroscopic portals, wherein said working devices being provided with encoder discs and optical sensors to determine position of the working devices, and the at least one data processing unit being configured to acquire and to process a third group of data relating to the position of the working devices and to extract from said third group of data a third group of position coordinates of said working devices; and wherein the working devices are each fixed to a mobile base, each mobile base is attached to one of two arms and the arms are integrally joined at their ends to shafts.
