Abstract: Disclosed is a mechanical telemanipulator handle to control surgical instruments with articulated end-effectors, such as dissectors, scissors or graspers, enhancing a surgeon's performance during various surgical procedures. These surgical instruments may be inserted into surgical incisions in a body of a patient and the articulated end-effector is mounted on the distal extremity of the instrument shaft, comprising a plurality of links interconnected by a plurality of joints, whose movements are remotely controlled at the telemanipulator's proximal handle. This remote actuation is accomplished through mechanical transmission, optimally along flexible elements, which are able to kinematically connect the end-effector with the handle such that the movements applied on the handle are reproduced by the end-effector at a predetermined scaled ratio.

Abstract: This system is composed by mechanical telemanipulators, with master-slave configurations, working together with suitable solutions for image acquisition and display, which are able to transmit, with optional magnification, images from the surgical area to the surgeon. Therefore, the surgeon's capacities and comfort are increased by enhancing the surgeon's motor and visual skills as well as the ergonomics while doing different surgical tasks through access incisions on the patient body. Aside from offering improved performance during procedures involving microsurgical techniques, this system also brings safety, intuitiveness, and cost-effectiveness advantages over current alternatives.
