Robotics has weaved its way into many different fields, and medicine is no exception; robot-assisted surgery has advanced dramatically over the past decade in almost every surgical subspecialty. Robot-assisted surgery is usually performed using surgical robot systems that involve a master-slave configuration, in which the "master" is a controller device that the surgeon manipulates to control a robotic arm. Such systems improve the dexterity and precision of surgeons by filtering out hand tremors and scaling their hand motions into smaller movements. They also reduce the risk of common surgical complications such as surgical site infection.

However, robot-assisted surgery comes with its own disadvantages, especially for the person performing the surgery. Robotic surgeons sometimes feel physical discomfort during surgery, with finger fatigue being common. This discomfort is associated with the way in which they grip the master controller. Two types of grips are usually used to control surgical robots: the "pinch grip" and "power grip." The pinch grip has been used in conventional surgeries for centuries; it involves using the thumb, middle, and index fingers to achieve high-precision movements. On the other hand, the power grip involves grabbing a handle with the entire hand and is more suitable for forceful work and large movements.
