Abstract

A medical instrument or device is used for resonant delivery of microwave power to tissue for the purpose of resection and coagulation of vessels during surgery and/or other medical procedures. The device enables delivery of large amounts of power to tissue without the need for ground pads by accomplishing an impedance match between tissue and the characteristic impedance of the waveguide that feeds power to it. The device includes a semi-rigid coaxial cable having a center conductor which protrudes from an outer conductor by a length set to be a λ/4 (quarter-wavelength) at the frequency of excitation in the dielectric environment of the tissue of interest. The coaxial cable is shrouded by a dielectric sleeve that provides both thermal and electrical insulation. Fitted against this sleeve is a conductive sleeve whose length is set to be a λ/4 (quarter-wavelength) at the frequency of excitation in the dielectric environment of the dielectric sleeve and the shroud. The device is connected to a feed cable at its proximal end, and can be connected to a source of microwave power. A directional coupler or other wave-sampling mechanism in combination with a power sensor and feedback circuit can be used to monitor reflected power from the device during the procedure, and to control the amount of power supplied to the device.

    • FIELD OF INVENTION
  • The present disclosure relates generally to medical instruments, and in particular to medical instruments in the field of tissue resection, coagulation, and hemostasis. Specifically, the present disclosure relates to a medical tool or device for resonant delivery of microwave power or energy to tissue for the purpose of resection and coagulation of vessels.
    • BACKGROUND
  • Use of energy to ablate, resect or otherwise cause necrosis in diseased tissue has proven beneficial both to human and to animal health. Electrosurgery is a well-established technique to use electrical energy at DC or radio frequencies (i.e. less than 500 kHz) to simultaneously cut tissue and to coagulate small blood vessels. Radio-frequency (RF) ablation of tumor tissue was developed from the basis of electrosurgery, and has been used with varied success to coagulate blood vessels while creating zones of necrosis sufficient to kill tumor tissue with sufficient margin.
  • Limitations of the above techniques center on the need for ground pads on the skin of the patient to provide a return path for the current, as well as the undesirable stimulation of the nervous system as cuts are being made; this usually requires injection of a temporary paralyzing agent. Limitations of tissue impedance, particularly as the tissue becomes desiccated or charred during the course of the procedure, limit the amount of current, and hence the amount of ablative power, that can be applied to the tissue. This in turn limits the size of vessels that can be effectively shut down.
  • Thus current procedures are limited when applied to resection of tumors from highly-vascularized organs, e.g. liver. Furthermore, the limitations of current and power limit the speed at which these procedures can be performed. Accordingly, there is a need for a device which overcomes the problems and disadvantages associated with current procedures, and which is an improvement thereover. The present disclosure fulfills this need.
    • SUMMARY
  • The present disclosure relates to delivery of microwave (e.g. approximately 800 MHz and higher frequencies) power to tissue for the purpose of ablating tissue or resecting tissue with little or no loss of blood.
  • The device enables delivery of large amounts of power (e.g. greater than 100 Watts) to tissue without the need for ground pads since it accomplishes an impedance match between tissue and the characteristic impedance of the waveguide that feeds power to it. This is accomplished in a hand-held format similar to many surgical tools. It can accept a variety of tips for different cutting and coagulation purposes. Furthermore, because of the impedance matching, reflected power from the tool is minimized. Reflected power can further be monitored at the generator or along the feed cable to use as feedback to the generator power control.
  • Numerous other advantages and features of the disclosure will become readily apparent from the following detailed description, from the claims and from the accompanying drawings in which like numerals are employed to designate like parts throughout the same.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • A fuller understanding of the foregoing may be had by reference to the accompanying drawings wherein:
  • FIG. 1 is a cross-sectional view of a preferred embodiment of the present disclosure, showing the arrangement of an impedance-matching sleeve and the tip.
  • FIG. 2 is a plan view of the preferred embodiment of the present disclosure encapsulated in a ceramic or plastic housing.
  • FIG. 3 is a schematic circuit diagram for a microwave power delivery and control system in accordance with the preferred embodiment of the present disclosure.
    • DESCRIPTION OF DISCLOSED EMBODIMENT(S)
  • While the invention is susceptible of embodiment in many different forms, there is shown in the drawings and will be described herein in detail one or more embodiments of the present disclosure. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention, and the embodiment(s) illustrated is/are not intended to limit the spirit and scope of the invention and/or the claims herein.
  • With reference to the drawings, an example of the preferred embodiment of the energy delivery device or microwave tissue resection tool of the present disclosure is shown in FIG. 1.
  • As illustrated in FIG. 1, a semi-rigid coaxial cable, preferably constructed of copper or silver with a suitable low-loss dielectric, forms the basis of the device. The cable's center conductor 10 protrudes from the outer conductor 12 by a length L1, which is set to be a λ/4 (quarter-wavelength) at the frequency of excitation (e.g. 915 MHz, 2.45 GHz, or another suitable frequency) in the dielectric environment of the tissue of interest. The cable can be chosen from commercially-available standards, but it should be thick enough to be rated for the power delivered.
  • The coaxial cable is shrouded by a dielectric sleeve 14 that provides both thermal and electrical insulation. Fitted against this sleeve is a conductive sleeve (e.g. made of copper or silver or another suitable conductor) whose length is set to be a λ/4 (quarter-wavelength) at the frequency of excitation (e.g. 915 MHz, 2.45 GHz, or another suitable frequency) in the dielectric environment of the dielectric sleeve 14 and the shroud 30 (FIG. 2). This conductive sleeve 16 contacts the outer conductor of the coaxial cable 12 at a point 18, where it is free to slide if necessary to fine-tune the impedance matching effect. It can then be fixed in place with adhesive or other suitable mechanism.
  • The protrusion of the coaxial cable's center conductor 10 is shrouded by a non-stick material 20 (e.g. PTFE or Teflon) to minimize adhesion of the device to the tissue. A tip 22 at the distal end of the device can be specially formed to maximize the electric field emanating from it. For example, the tip 22 can be sharpened and optionally exposed directly to the tissue.
  • The device is connected to a feed cable at its proximal end 26. This cable can be optionally connectorized, by attaching any suitable connector known in the art of connecting cable, to simplify exchange of the device.
  • As shown in FIG. 2, the device can be enshrouded in a suitable ceramic or plastic housing 30, which can contain cooling fluid (e.g. air, nitrogen, water, etc) and microwave absorbing material (e.g. polyiron) to minimize radiation from the tool to the extent necessary or desired.
  • As shown in FIG. 3, the device 30 can be used in a system by which it is connected to a source of microwave power 36 via a cable 32. A directional coupler or other wave-sampling mechanism 34 in combination with a power sensor and feedback circuit 38 can be used to monitor reflected power from the device during the procedure. If the amount of reflected power exceeds a threshold, power from the generator 36 can be reduced to minimize heating of the device 30, while if the amount of reflected power is below a threshold, power can be increased to speed the procedure.
  • It is to be understood that the embodiment(s) herein described is/are merely illustrative of the principles of the present invention. Various modifications may be made by those skilled in the art without departing from the spirit or scope of the claims which follow.
