Abstract
Surgical instruments for use in minimally invasive surgery are described. The instruments have parts that are easily separable and easily assembled. A reciprocal slide member is operable by a cam portion of a lever received in a slot in the slide member. There is no mechanical connection between the lever and the slide member. The slide member is connected to elongate surgical implement components that extend through an elongate support member. The elongate surgical implement components are capable of reciprocal movement in the proximal-distal direction. In some embodiments, the elongate surgical implements can be used for measuring distances arthroscopically; these surgical implements can have beveled ends for more precise measurement of distances. The surgical instrument can be modular, with separate tool and actuator modules. The surgical instrument can be used with any implement that can be operated by reciprocal motion.
