  • Method and device to reduce needle insertion force
    Patent number: 6626848
    Abstract: The present invention relates to devices and methods to reduce the insertion force of a medical needle using reciprocal rotation motion about the longitudinal axis. The device of the invention converts continuous rotational motion to reciprocal rotational motion for the beveled needle. A needle using reciprocal rotational motion creates a slit in the tissue, sufficient in size to equal the maximum circumference of the needle prior to insertion of the needle. The insertion force will decrease as the speed of the reciprocal rotational motion increases until a steady state insertion force is achieved.
