Abstract

A medical device for reducing the force necessary to penetrate tissue by reciprocating a cutting member in a direction that is parallel to the tissue and using a feedback system to indicate when different layers of tissue are being encountered. Although a variety of driving mechanisms can be used to generate the reciprocating motion, the preferred method is via the use of piezoelectric elements, such as flextensional transducers, amplified piezoelectric actuators, along with a bender bar, and voice coil motor motors. The feedback system utilizes any number of acoustic properties, such as controller impedance, phase lag, conductivity, or resistivity density variable. A vibrating reference member is passed through various tissues and the change in acoustic property is associated with the tissue. A look-up table can be developed that can be used by the feedback system to automatically alert the medical operator (e.g., visual, audible, tactile or display) that a different tissue is being encountered. A power shut-off can be provided as another alternative when a different tissue is encountered.
