Definitions
- the present disclosure relates to electrosurgical instruments. More particularly, the present disclosure relates to temperature-sensing electrically-conductive tissue-contacting plates configured for use in electrosurgical jaw members, electrosurgical systems including the same, and methods of controlling vessel sealing using the same.
- Electrosurgical instruments such as electrosurgical forceps
- Electrosurgery involves the application of thermal and/or electrical energy to cut, dissect, ablate, coagulate, cauterize, seal or otherwise treat biological tissue during a surgical procedure.
- Electrosurgery is typically performed using an electrosurgical generator operable to output energy and a handpiece including a surgical instrument (e.g., end-effector) adapted to transmit energy to a tissue site during electrosurgical procedures.
- Electrosurgery is typically performed using either a monopolar or a bipolar instrument.
- monopolar electrosurgery devices use an instrument with a single, active electrode to deliver energy from an electrosurgical generator to tissue, and a patient return electrode or pad that is attached externally to the patient (e.g., a plate positioned on the patient's thigh or back) as the means to complete the electrical circuit between the electrosurgical generator and the patient.
- a patient return electrode or pad that is attached externally to the patient (e.g., a plate positioned on the patient's thigh or back) as the means to complete the electrical circuit between the electrosurgical generator and the patient.
- the electrosurgical energy When the electrosurgical energy is applied, the energy travels from the active electrode, to the surgical site, through the patient and to the return electrode.
- Bipolar electrosurgical devices include two electrodes that are located in proximity to one another for the application of current between their respective surfaces. Bipolar electrosurgical current travels from one electrode, through the intervening tissue to the other electrode to complete the electrical circuit.
- Bipolar instruments generally include end-effectors, such as graspers, cutters, forceps, dissectors and the like.
- Bipolar electrosurgical forceps utilize two generally opposing electrodes that are operably associated with the inner opposing surfaces of the end-effectors and that are both electrically coupled to an electrosurgical generator.
- the end-effector assembly generally includes opposing jaw members pivotably mounted with respect to one another. In a bipolar configuration, only the tissue grasped between the jaw members is included in the electrical circuit. Because the return function is performed by one jaw member of the forceps, no patient return electrode is needed.
- Jaw member components of end-effector assemblies for use in electrosurgical instruments are required to meet specific tolerance requirements for proper jaw alignment and other closely-toleranced features. Gap tolerances and/or surface parallelism and flatness tolerances are parameters that, if properly controlled, can contribute to a consistent and effective tissue seal. Thermal resistance, strength and rigidity of surgical jaw members also play a role in determining the reliability and effectiveness of electrosurgical instruments.
- a surgeon can cauterize, coagulate, desiccate and/or seal tissue and/or simply reduce or slow bleeding by controlling the intensity, frequency and duration of the electrosurgical energy applied through the jaw members to the tissue.
- mechanical factors such as the pressure applied to the vessel or tissue between opposing jaw members and the gap distance between the electrically-conductive tissue-contacting surfaces (electrodes) of the jaw members play a role in determining the resulting thickness of the sealed tissue and effectiveness of the seal.
- Accurate application of pressure is important to oppose the walls of the vessel; to reduce the tissue impedance to a low enough value that allows enough electrosurgical energy through the tissue; to overcome the forces of expansion during tissue heating; and to contribute to the end tissue thickness which is an indication of a good seal.
- a variety of instruments have been developed that utilize technology to form a vessel seal utilizing a combination of pressure, gap distance between opposing surfaces and electrical control to effectively seal tissue or vessels.
- a generator such as a radio-frequency (RF) electrosurgical generator
- RF radio-frequency
- the system provides an end tone that indicates to the surgeon that a procedure, such as a vessel-sealing procedure, is complete.

- the jaw members are moveable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween.
- the electrosurgical system also includes an electrosurgical power generating source and a controller operably coupled to the electrosurgical power generating source.
- the controller is configured to control one or more operating parameters associated with the electrosurgical power generating source based on one or more signals indicative of a tissue impedance value and indicative of a temperature sensed by the one or more temperature sensors.

- the method also includes the steps of moving at least one jaw member relative to the other jaw member to grasp tissue between the tissue-contacting surface of each one of the temperature-sensing electrically-conductive tissue-contacting plates, transmitting energy from an electrosurgical power generating source to at least one of the jaw members, and controlling one or more operating parameters associated with the electrosurgical power generating source based on one or more signals indicative of a temperature sensed by one or more temperature sensors.
- a method of controlling vessel sealing includes the initial step of providing an electrosurgical instrument having an end-effector assembly including opposing jaw members movably mounted with respect to one another. At least one of the jaw members includes a temperature-sensing electrically-conductive tissue-contacting plate having a tissue-contacting surface and a bottom surface.
- the method also includes the steps of positioning the jaw members to energize tissue, transmitting energy from an electrosurgical power generating source to the at least one of the jaw members, transmitting one or more signals indicative of a tissue impedance value and a tissue temperature value to a controller operably associated with the electrosurgical power generating source, and controlling one or more operating parameters associated with the electrosurgical power generating source based on the one or more signals indicative of the tissue impedance value and the tissue temperature value sensed by the one or more temperature sensors.

Description
- This application is a continuation of U.S. patent application Ser. No. 14/538,402, filed on Nov. 11, 2014, which claims the benefit of the filing date of provisional U.S. Patent Application No. 61/938,232, filed on Feb. 11, 2014.
- The present disclosure relates to electrosurgical instruments. More particularly, the present disclosure relates to temperature-sensing electrically-conductive tissue-contacting plates configured for use in electrosurgical jaw members, electrosurgical systems including the same, and methods of controlling vessel sealing using the same.
- Electrosurgical instruments, such as electrosurgical forceps, are well known in the medical arts. Electrosurgery involves the application of thermal and/or electrical energy to cut, dissect, ablate, coagulate, cauterize, seal or otherwise treat biological tissue during a surgical procedure. Electrosurgery is typically performed using an electrosurgical generator operable to output energy and a handpiece including a surgical instrument (e.g., end-effector) adapted to transmit energy to a tissue site during electrosurgical procedures. Electrosurgery is typically performed using either a monopolar or a bipolar instrument.
- The basic purpose of both monopolar and bipolar electrosurgery is to produce heat to achieve the desired tissue/clinical effect. In monopolar electrosurgery, devices use an instrument with a single, active electrode to deliver energy from an electrosurgical generator to tissue, and a patient return electrode or pad that is attached externally to the patient (e.g., a plate positioned on the patient's thigh or back) as the means to complete the electrical circuit between the electrosurgical generator and the patient. When the electrosurgical energy is applied, the energy travels from the active electrode, to the surgical site, through the patient and to the return electrode.
- In bipolar electrosurgery, both the active electrode and return electrode functions are performed at the site of surgery. Bipolar electrosurgical devices include two electrodes that are located in proximity to one another for the application of current between their respective surfaces. Bipolar electrosurgical current travels from one electrode, through the intervening tissue to the other electrode to complete the electrical circuit. Bipolar instruments generally include end-effectors, such as graspers, cutters, forceps, dissectors and the like.
- Bipolar electrosurgical forceps utilize two generally opposing electrodes that are operably associated with the inner opposing surfaces of the end-effectors and that are both electrically coupled to an electrosurgical generator. In bipolar forceps, the end-effector assembly generally includes opposing jaw members pivotably mounted with respect to one another. In a bipolar configuration, only the tissue grasped between the jaw members is included in the electrical circuit. Because the return function is performed by one jaw member of the forceps, no patient return electrode is needed.
- A variety of types of end-effector assemblies have been employed for various types of electrosurgery using a variety of types of monopolar and bipolar electrosurgical instruments. Jaw member components of end-effector assemblies for use in electrosurgical instruments are required to meet specific tolerance requirements for proper jaw alignment and other closely-toleranced features. Gap tolerances and/or surface parallelism and flatness tolerances are parameters that, if properly controlled, can contribute to a consistent and effective tissue seal. Thermal resistance, strength and rigidity of surgical jaw members also play a role in determining the reliability and effectiveness of electrosurgical instruments.
- By utilizing an electrosurgical forceps, a surgeon can cauterize, coagulate, desiccate and/or seal tissue and/or simply reduce or slow bleeding by controlling the intensity, frequency and duration of the electrosurgical energy applied through the jaw members to the tissue. During the sealing process, mechanical factors such as the pressure applied to the vessel or tissue between opposing jaw members and the gap distance between the electrically-conductive tissue-contacting surfaces (electrodes) of the jaw members play a role in determining the resulting thickness of the sealed tissue and effectiveness of the seal. Accurate application of pressure is important to oppose the walls of the vessel; to reduce the tissue impedance to a low enough value that allows enough electrosurgical energy through the tissue; to overcome the forces of expansion during tissue heating; and to contribute to the end tissue thickness which is an indication of a good seal. A variety of instruments have been developed that utilize technology to form a vessel seal utilizing a combination of pressure, gap distance between opposing surfaces and electrical control to effectively seal tissue or vessels.
- Methods and systems have been developed for controlling an output of a generator, such as a radio-frequency (RF) electrosurgical generator, based on sensor signals indicative of impedance changes at a surgical site. In some systems employing changes in impedance to control the amount of electrosurgical energy applied to tissue, when the sensor signal meets a predetermined level based on a control algorithm, the system provides an end tone that indicates to the surgeon that a procedure, such as a vessel-sealing procedure, is complete. In generators employing an impedance-based control algorithm, impedance is a proxy for temperature, and there are cases where an end tone may be given when no tissue sealing has occurred because the impedance proxy was incorrect.
- A continuing need exists for methods and systems for controlling one or more operating parameters of an electrosurgical power generating source based on one or more signals indicative of a temperature sensed by one or more temperature sensors. A continuing need exists for temperature-sensing devices that can be readily integrated into the manufacturing process for electrosurgical jaw members.

Like reference numerals may refer to similar or identical elements throughout the description of the figures. As shown in the drawings and as used in this description, and as is traditional when referring to relative positioning on an object, the term “proximal” refers to that portion of the apparatus, or component thereof, closer to the user and the term “distal” refers to that portion of the apparatus, or component thereof, farther from the user.
- This description may use the phrases “in an embodiment,” “in embodiments,” “in some embodiments,” or “in other embodiments,” which may each refer to one or more of the same or different embodiments in accordance with the present disclosure.
- As it is used in this description, “electrically-conductive tissue-contacting plate” generally refers to an electrically-conductive member including one or more tissue engaging surfaces that can be used to transfer energy from an electrosurgical power generating source, such as RF electrosurgical generator, to tissue. As it is used in this description, “electrically conductive”, or simply “conductive”, generally refers to materials that are capable of electrical conductivity, including, without limitation, materials that are highly conductive, e.g., metals and alloys, or materials that are semi-conductive, e.g., semi-conducting materials and composites. As it is used in this description, “transmission line” generally refers to any transmission medium that can be used for the propagation of signals from one point to another.
- Vessel sealing or tissue sealing utilizes a combination of radiofrequency energy, pressure and gap control to effectively seal or fuse tissue between two opposing jaw members or sealing plates thereof. Vessel or tissue sealing is more than “cauterization” which may be defined as the use of heat to destroy tissue (also called “diathermy” or “electrodiathermy”), and vessel sealing is more than “coagulation” which may be defined as a process of desiccating tissue wherein the tissue cells are ruptured and dried. As it is used in this description, “vessel sealing” generally refers to the process of liquefying the collagen, elastin and ground substances in the tissue so that it reforms into a fused mass with significantly-reduced demarcation between the opposing tissue structures.
- Various embodiments of the present disclosure provide electrosurgical instruments suitable for sealing, cauterizing, coagulating, desiccating, and/or cutting tissue, e.g., vessels and vascular tissue, during a surgical procedure. Embodiments of the presently-disclosed electrosurgical instruments may be suitable for utilization in endoscopic surgical procedures and/or suitable for utilization in open surgical applications. Embodiments of the presently-disclosed electrosurgical instruments may be implemented using electrosurgical energy at radio frequencies (RF) and/or at other frequencies.
- Various embodiments of the present disclosure provide electrosurgical instruments that include an end-effector assembly having jaw members including a temperature-sensing electrically-conductive tissue-contacting plate including one or more temperature sensors coupled to a bottom surface thereof. One or more operating parameters associated with an electrosurgical power generating source may be controlled based on one or more signals indicative of a temperature sensed by the one or more temperature sensors coupled to the bottom surface of each one of the temperature-sensing electrically-conductive tissue-contacting plates. The presently-disclosed tissue-contacting plate embodiments may include a plurality of zones, wherein each zone includes one or more temperature sensors (and/or pressure sensors), e.g., to provide feedback to an electrosurgical power generating source configured to turn on/off different zones to provide more uniform heating patterns across the jaw members and/or to help control thermal spread.
- The various embodiments disclosed herein may also be configured to work with robotic surgical systems and what is commonly referred to as “Telesurgery.” Such systems employ various robotic elements to assist the surgeon in the operating theater and allow remote operation (or partial remote operation) of surgical instrumentation. Various robotic arms, gears, cams, pulleys, electric and mechanical motors, etc. may be employed for this purpose and may be designed with a robotic surgical system to assist the surgeon during the course of an operation or treatment. Such robotic systems may include, remotely steerable systems, automatically flexible surgical systems, remotely flexible surgical systems, remotely articulating surgical systems, wireless surgical systems, modular or selectively configurable remotely operated surgical systems, etc.
- The robotic surgical systems may be employed with one or more consoles that are next to the operating theater or located in a remote location. In this instance, one team of surgeons or nurses may prep the patient for surgery and configure the robotic surgical system with one or more of the instruments disclosed herein while another surgeon (or group of surgeons) remotely controls the instruments via the robotic surgical system. As can be appreciated, a highly skilled surgeon may perform multiple operations in multiple locations without leaving his/her remote console which can be both economically advantageous and a benefit to the patient or a series of patients.
- The robotic arms of the surgical system are typically coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the working ends of any type of surgical instrument (e.g., end-effectors, graspers, knifes, scissors, etc.) which may complement the use of one or more of the embodiments described herein. In various embodiments disclosed herein, an end-effector assembly may be coupled to a pair of master handles by a controller. The movement of the master handles may be scaled so that the working ends have a corresponding movement that is different, smaller or larger, than the movement performed by the operating hands of the surgeon. The scale factor or gearing ratio may be adjustable so that the operator can control the resolution of the working ends of the surgical instrument(s).
- The master handles may include various sensors to provide feedback to the surgeon relating to various tissue parameters or conditions, e.g., tissue resistance due to manipulation, cutting or otherwise treating, pressure by the jaw members onto the tissue, tissue temperature, tissue impedance, etc. As can be appreciated, such sensors provide the surgeon with enhanced tactile feedback simulating actual operating conditions. The master handles may also include a variety of different actuators for delicate tissue manipulation or treatment further enhancing the surgeon's ability to mimic actual operating conditions.
