The method also includes compensating the measured acoustic impedance for clamp pressure and monitoring the coagulation using at least the compensated measured acoustic impedance. A first medical treatment system includes an energy-based clamp coagulator, an acoustic-impedance measurer, and a force measurer. A second system includes an energy-based clamp coagulator having a clamping member which includes, or is adapted to function as, an electrical-impedance-measuring electrode for measuring an electrical impedance of the clamped patient tissue. A third system includes an energy-based clamp coagulator having a clamping member which includes, or is adapted to function as, a temperature sensor for measuring a temperature of the clamped patient tissue.
FIELD OF THE INVENTION The present invention is related generally to medical treatment systems and methods, and more particularly to an energy-based medical treatment system and to an energy-based medical treatment method.
BACKGROUND OF THE INVENTION Energy-based medical treatment systems are known which include a clamp coagulator in the form of an ultrasonic surgical shears having an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, a tissue pad attached to the clamping arm, and a device for exerting a clamping force on the clamping arm which creates a clamping pressure on a blood vessel which is positioned between the clamping surface area of the tissue pad and the blade. The result of the ultrasonically-vibrating ultrasonic surgical blade and the clamping pressure on the blood vessel is a coaptation of the blood vessel (a bringing together of the walls of the blood vessel), a transection (a cutting) of the coaptated blood vessel, and a coagulation (a sealing) of the coaptated cut ends of the blood vessel. Energy-based medical treatment systems in the form of RF (radio-frequency) clamp coagulators are also known.
SUMMARY OF THE INVENTION A method of the invention is for medical treatment and includes steps a) through g). Step a) includes obtaining an energy-based clamp coagulator. Step b) includes applying a clamping force to patient tissue using the energy-based clamp coagulator. Step c) includes beginning coagulating the patient tissue using the energy-based clamp coagulator. Step d) includes determining the clamping force. Step e) includes measuring the acoustic impedance of the patient tissue. Step f) includes compensating the measured acoustic impedance of the patient tissue for clamp pressure using at least the determined clamping force. Step g) includes monitoring the coagulation of the patient tissue using at least the compensated measured acoustic impedance.
Referring now to the Figures, in which like numerals indicate like elements, FIG. 1 illustrates a method of the invention with FIGS. 2-3 illustrating an embodiment of an energy-based medical treatment system 10 as one example of apparatus for carrying out the method. The method is for medical treatment and includes steps a) through g). Step a) is labeled as �Obtain Clamp Coagulator� in block 12 of FIG. 1. Step a) includes obtaining an energy-based clamp coagulator 14. Step b) is labeled as �Apply Clamping Force� in block 16 of FIG. 1. Step b) includes applying a clamping force to patient tissue 18 using the energy-based clamp coagulator 14. Step c) is labeled as �Begin Coagulating Patient Tissue� in block 20 of FIG. 1. Step c) includes beginning coagulating the patient tissue 18 using the energy-based clamp coagulator 14. Step d) is labeled as �Determine Clamping Force� in block 22 of FIG. 1. Step d) includes determining the clamping force. Step e) is labeled as �Measure Acoustic Impedance� in block 24 of FIG. 1. Step e) includes measuring the acoustic impedance of the patient tissue 18. Step f) is labeled as �Compensate The Measured Impedance� in block 26 of FIG. 1. Step f) includes compensating the measured acoustic impedance of the patient tissue 18 for clamp pressure using at least the determined clamping force. Step g) is labeled as �Monitor Coagulation� in block 28 of FIG. 1. Step g) includes monitoring the coagulation of the patient tissue 18 using at least the compensated measured acoustic impedance.
