Abstract
A surgical instrument includes a handle having a pair of actuating wings and a removable instrument tip. The instrument tip is constructed to perform a surgical operation. The handle includes an axially movable slider actuated by the actuating wings which operate the instrument tip. A shaft extends through the handle and is coupled to the instrument tip so that rotation of the shaft rotates the tip without interfering with the axial movement of the slider. The gripping surface of the actuating wings have a rounded surface to allow limited rotational movement of the instrument in the user's hand. The gripping surfaces are inclined toward the instrument tip to resist the handle slipping from the user's hand during use in the near vertical orientation.
