Abstract

The present invention relates to a jaw structure for a surgical instrument. The surgical instrument jaw structure, comprises: a pair of jaws mounted at the end portion of the surgical instrument and used for a grip operation; an elastic skin applied to a surface facing the pair of jaws, the elastic skin being transformed when pressed by an object according to the grip operation of the jaws; and a sensing block interposed between the jaw and the elastic skin, for measuring a reaction force applied to the jaws based on the degree of transformation of the elastic skin. Since the grip surface of the pair of jaws is covered with an elastic material, it is easier to grip an object during a surgical operation, and damage to the object can be minimized even if the jaws are gripped with an excessive force. A force sensor array is arranged on the other side of the elastic skin to intuitively sense the reaction force applied to the jaws, in a manner similar to the way a human feels.
