Definitions
- the following disclosure relates to a system and method for monitoring macroscopic tissue modifications during an electrosurgical procedure, and more particularly to a system and method that quantifies the progress of tissue thermal damage and dehydration using optical monitoring.
- Electrosurgical forceps use a combination of mechanical pressure and electrical energy to effect hemostasis, by heating tissue and blood vessels to coagulate, cauterize and/or seal tissue.
- a surgeon can cauterise, coagulate, desiccate and/or slow bleeding.
- the delivered energy must be controlled in real-time as a function of the tissue state so that a reliable and reproducible surgical effect is generated.
- thermal damage is used to describe any bio-structural alteration of the tissue induced by heat. Thermal damage generally includes several biophysical modifications of the tissue that can ultimately lead to tissue death or denaturation - the loss of tridimensional protein structure.
- impedance is often used to control the delivery of RF energy during tissue fusion, because it is relatively easy to measure and because dehydration is believed to reduce conductivity and, hence, increase impedance during the final stage of the fusion process.
- hydration does not completely correlate to impedance.
- impedance tends to be a less useful control parameter for the overall tissue sealing process.
- Optical spectroscopy has the potential to provide more detailed information on the overall state of the tissue, since it allows information to be gathered on both the tissue structure and the tissue's biochemical makeup. In this case, there are much more significant metrological challenges, since the detectable signals are generally very weak. Further, algorithms are typically required to extract directly relevant information about the tissue-state from the raw optical signals.
- the object of the present invention is to provide a more accurate system and method of optically monitoring and controlling the RF tissue fusion processes.
- the system and method disclosed herein is based on a system that combines transmission and reflection spectroscopy to provide continuous data with an algorithm for accurate quantification of components such as water even in tissue with strongly varying scattering properties.
- a system for monitoring tissue modifications during an electrosurgical procedure includes an electrical generator for generating RF energy and an electrosurgical apparatus including a pair of jaw members configured to grasp tissue therebetween, deliver RF energy to the tissue, and allow optical measurement of the tissue state by transmission and reflection spectroscopy.
- the present disclosure relates to a system for monitoring and controlling tissue modification during an electrosurgical procedure and includes an electrosurgical apparatus that couples to an electrosurgical generator for generating electrical energy.
- the electrosurgical apparatus e.g., a forceps
- the electrosurgical apparatus includes a pair of jaw members configured to grasp tissue therebetween and allow light transmission therethrough.
- the jaw members (or a portion thereof) may be transparent or translucent to accomplish this purpose.
- the system also includes an optical system having one or more optical sources which generate light (e.g., an optical transmission signal) of one or more wavelengths. At least a portion of the light is transmitted through tissue and at least a portion of the light is reflected from the tissue.
- One or more optical detectors are included and are configured to analyze the portion of the light of being transmitted through tissue. The same or a different optical detector is configured to analyze the portion of the light being reflected from the tissue.
- a processor is operatively coupled to the optical system and to the electrosurgical generator and is configured to control the delivery of electrical energy from the electrosurgical generator to tissue based on information provided by the optical system by the detector(s).
- the optical system controls the electrosurgical generator in real time during the electrosurgical procedure. In another embodiment, the optical system detects thermal damage of tissue and/or hydration of tissue and cooperates with the electrosurgical generator via the processor to control the delivery of electrical energy to the tissue.
- the optical system may include a continuous wave device, a superluminescent light-emitting diode array and/or an incandescent lamp.
- two different optical detectors may be utilized with the processor to analyze the signals - one to analyze transmitted signals and one to analyze reflected signals.
- a Fabry-Perot interferometer or a dispersive spectrometer may be utilized as an optical detector.
- the present disclosure also relates to a method for monitoring and controlling the delivery of electrosurgical energy to tissue during an electrosurgical procedure and includes the steps of: providing an electrosurgical apparatus including a pair of jaw members configured to grasp tissue therebetween and allow light transmission therethrough; generating electrical energy through tissue held between jaw members; generating light of one or more wavelengths at tissue; analyzing a spectral content of the light being transmitted through tissue and providing information relating thereto back to a processor; analyzing a spectral content of the light being reflected from the tissue and providing information relating thereto back to the processor; and controlling the delivery of electrical energy from the electrosurgical generator to tissue based information provided to the processor.
- the processor resumes controlling the delivery of electrosurgical energy based on the optical transmission signal being transmitted through tissue until the electrosurgical procedure is completed.
- Fig. 3 is an enlarged, front perspective view of the end effector assembly of Fig. 2;
- Fig. 6A is a graph showing the transmitted light signal over time during a tissue fusion process according to an embodiment of the present disclosure.
- Fig. 6B is a graph showing the reflected light signal over time during a tissue fusion process according to an embodiment of the present disclosure.
- Such an analysis may allow improved understanding of the tissue modifications that lead to the high fusion quality.
- Processing of the reflection spectroscopy data allows control to be maintained, after it has been effectively extinguished due to increased scattering.
- the processed data obtained during the fusion process may be incorporated into a suitable feedback loop to control delivery of RF energy so that the optimum tissue transformations are obtained.
- generator 101 may include all components and parts as needed for system 10 to function and operate as intended.
- Cable 310 may be internally divided into one or more cable leads (not shown) that are designed to transmit electrical potentials through their respective feed paths through the forceps 200 to the end effector assembly 208 such that upon activation of a switch 204 (See Fig. 2), energy is transmitted from the various cable leads to the respective feed paths and energy is transmitted through the tissue.
- end effector assembly 208 is attached at the distal end 207 of shaft 205 and includes a pair of opposing jaw members 301 and 304.
- Movable handle 215 of handle assembly 230 is ultimately connected to a drive assembly (not shown) which, together, mechanically cooperate to impart movement of the jaw members 301 and 304 from an open position wherein the jaw members 301 and 304 are disposed in spaced relation relative to one another, to a clamping or closed position wherein the jaw members 301 and 304 cooperate to grasp tissue therebetween.
- a drive assembly not shown
- an optical transmission port 305a for the delivery of light and an optical collection port 305b for reception of reflected light 305b are defined on the first jaw member 301.
- Light from the optical source 105 can be delivered via an optical fibre 106a running through the shaft 205 to one or both jaw members 301 and 304 depending upon the particular configuration of the forceps 200.
- Suitable optical fibres include single-or multi-mode fibres, formed from glass or plastic.
- the light path may be turned through approximately 90 degrees on exit from the fibre 106a and collimated by lens 107 to pass through the first translucent port 305a of the jaw member 301.
- Suitable components to achieve a change in direction of the optical path may include prisms, small mirrors and moulded plastic light pipes.
- Suitable elements to achieve collimation may include conventional lenses, ball lenses and graded index rod lenses.
- the lens 110a, fibre 111 and folded light path needed to collect reflected light from the second translucent port 305b may also be provided in the jaw member 301 in a similar way and using similar components.
- the translucent port 305b, lens 108a, fibre 109 and folded light path needed to collect transmitted light may also be provided in the second jaw 304 in a similar way.
- Light may be delivered to and collected from the end effector assembly 208 of the forceps 200 via three optical fibres 106a, 111 and 109 conveniently arranged as a single with electrical interconnects that carry power to the RF electrodes in the jaw members 310 and 304.
- the individual optical fibres 106a, 111 and 109 may be separated and attached to optical fibre connectors (not shown) to allow removable or selectively detachable connection to the optical source 105 and optical detection system 112.
- the optical detection device 112 includes two equivalent systems for separately analysing the spectral content of the transmitted and reflected light.
- the nature of the detection systems depends on the type of optical source utilized. For example, for a continuous broadband source such as a superluminescent diode array, scanning or staring filters such as Fabry-Perot interferometers or dispersive spectrometers are suitable. For a tuneable narrowband source, fixed detectors are suitable.
- the processor 113 may be a microprocessor, laptop or personal computer connected to the light source 105, the detection system 112 and the electrosurgical generator 101 via suitable interface buses that allow transfer of command instructions and data.
- An algorithm may then be constructed to control the RF power applied to the tissue by the electrosurgical generator 101 and the electrosurgical instrument, e.g., forceps 200, so that the concentration of water in tissue is reduced at a controlled rate to a controlled final level corresponding to a controlled final hydration state.
