MAGNETIC ACTIVATION OF MONOPOLAR AND BIPOLAR DEVICES

摘要

A system for providing current to perform a surgical procedure includes an electrosurgical device having a conductive cutting wire and a power source with a power cord providing current to the cutting wire from a power source. The power cord and device are connected via a magnetic connection. The magnetic connection includes a device housing coupled to a cord housing, where a magnetic post is received in a recess for mechanically and electrically connecting the cutting wire and an active wire of the power cord. The recess and the magnetic post can be coaxial, with the axes being perpendicular to longitudinal axes of the device housing and the cord housing so that the connection can withstand a force exerted along the longitudinal axis, but a sufficient force transverse to the longitudinal axes and along the axes of the recess and the post can de-couple the magnetic connection.

1. A system for providing an electrical current during surgery, the system comprising:
an elongate electrosurgical device having a distal end and proximal end and a longitudinal device axis extending therebetween; a conductive cutting wire mounted to the device and extending along the longitudinal axis, the conductive cutting wire having an exposed cutting portion at the distal end; a device housing at the proximal end of the device, the device housing at least partially covering the conductive cutting wire mounted therein; an elongate cord having proximal and distal ends and a longitudinal cord axis therebetween with an active wire therein for transferring power from a power source; a cord housing at the distal end of the elongate cord, the cord housing covering at least a portion of the active wire; a magnetic connection between the device housing and the cord housing, the magnetic connection comprising both a mechanical and electrical connection; a recess of the magnetic connection extending generally transverse to the longitudinal axes of the device housing and the cord housing, the recess comprising a recessed magnetic surface; a magnetic post of the magnetic connection extending generally transverse to the longitudinal axes of the device housing and the cord housing and sized to correspond to the shape of the recess; wherein the magnetic surface is electrically connected to one of the conductive wire or the active wire; wherein the magnetic post is electrically connected to the other of the conductive wire or the active wire; wherein the magnetic post contacts the magnetic surface and is magnetically and electrically coupled thereto for transferring power from the active wire to the conductive wire; and wherein the magnetic post is received in the recess perpendicular to the longitudinal axes of the device housing and the cord housing.
