Abstract
A handle and methods for its use are provided for actuating surgical components such as blades, clamps, punches, needles, shears, etc., primarily for use in cardiovascular or arthroscopic surgery. The handle is a single-piece handle, including an outer portion and an inner portion. The inner portion is substantially within the outer portion, and includes an actuating component, and a guiding component connected to the actuating component. The actuating component includes a finger grip, and a spring force component which biases the finger grip and the guiding component to extend and towards a distal tip of the neck. A stress limiting component limits stress at a critical point of the spring force component by limiting movement of the spring force component at the critical point during actuation of the actuating component. The guiding component is adapted for movement along a longitudinal axis of the handle, in response to actuation and release of the actuating component, thus allowing a surgical component connected to a distal tip of the guiding component to function.
