[0023] The applicant of this application has the following concurrently filed U.S. patent applications, the disclosures of each of which are incorporated herein by reference in their entirety: U.S. Patent Application No. 18 / 950,801 entitled “IMPROVED FILTER LIFE IN SURGICAL Smoke EVACUATION SYSTEMS”; U.S. Patent Application No. 18 / 950,899, entitled “AIR MANAGEMENT IN SURGICAL SMOKE EVACUATION SYSTEMS”; and U.S. Patent Application No. 18 / 951,342, entitled “Setting EVACUATION MOTOR SPEEDS FOR SURGICAL TOOL EVACUATION MODULES”.

[0024] This disclosure relates to energy devices, blowing systems for delivering blown gas to a patient, and extraction systems for removing smoke and / or other fluids and / or particles from a surgical site.

[0025] Smoke is typically generated during surgical procedures utilizing one or more energy devices supplied with energy (power) from a generator. These energy devices use energy to affect (treat) tissue and include devices with tissue-contact electrodes, such as electrosurgical devices with one or more radiofrequency (RF) electrodes, and devices with vibrating surfaces, such as ultrasonic devices with an ultrasonic scalpel. For electrosurgical devices, the generator is configured to generate an oscillating current to power the electrodes. For ultrasonic devices, the generator is configured to generate ultrasonic vibrations to power the ultrasonic scalpel. The generator is further described herein. A degassing module is used to control (drain) the amount of smoke generated by the energy device during its use.

[0026] Figure 1 This is a block diagram of a computer-implemented interactive surgical system 100 (hereinafter referred to as "surgical system 100") that can be used according to at least one aspect of this disclosure. Surgical system 100 includes one or more sub-surgical systems 102 and a cloud-based system (e.g., cloud 104), which may include a remote server 113 communicating with a storage device 105. Each sub-surgical system 102 includes at least one surgical hub 106 communicating with the cloud 104, which may include the remote server 113.

[0027] In one example, such as Figure 1 As illustrated, subsurgical system 102 includes visualization system 108, robotic system 110, and handheld intelligent surgical instruments 112, which are configured to communicate with each other and / or with hub 106. In some aspects, each subsurgical system 102 may include M hubs 106, N visualization systems 108, O robotic systems 110, and P handheld intelligent surgical instruments 112, where M, N, O, and P are integers greater than or equal to one. Surgical system 100 is described in more detail in U.S. Patent No. 11,666,368, entitled “METHOD FOR CONSTRUCTING AND USING A MODULARSURGICAL ENERGY SYSTEM WITH MULTIPLE DEVICES,” published June 6, 2023, the entire contents of which are incorporated herein by reference.

[0028] Now for reference Figure 2 Example surgical hub 106 ( Figure 1The system can be embodied as a modular surgical system 200, which may include various different modules 201 capable of being connected together in a stacked configuration. In one aspect, the modules 201 may be physically and communicatively coupled together when stacked or otherwise connected together to form a single component. Furthermore, the modules 201 may be interchangeably connected together in different combinations or arrangements. In one aspect, each module in the module 201 may include a consistent or universal array of connectors disposed along its upper and lower surfaces, thereby allowing any module 201 to be connected to another module 201 in any arrangement (the difference being that, in some aspects, a particular module type (such as head module 202) may be configured to be used as, for example, the topmost module within a stack). In another aspect, the modular surgical system 200 may include a housing configured to receive and retain the modules 201. The modular surgical system 200 may also include various different parts or accessories that can also be connected to or otherwise associated with the modules 201.

[0029] The modular surgical system 200 can be assembled from a variety of different modules 201, some examples of which are shown in... Figure 2 As illustrated below. Each module in the different types of modules 201 can provide different functionalities, thereby allowing the modular surgical system 200 to be assembled into different configurations to customize the functionality and capabilities of the modular surgical system 200 (e.g., by customizing the modules 201 included in each modular surgical system 200). Modules 201 of the modular surgical system 200 may include, for example, a head module 202 (which may include a display 206), an energy module 204, a suction module 208, an inhalation module 210, and a visualization module 212.

[0030] In one aspect, the head module 202 is configured to function as a top or uppermost module within a modular surgical system stack, and therefore may be connector-free along its top surface. In another aspect, the head module 202 can be configured to be positioned at the bottom or lowermost module (i.e., the "footer" module) within the modular surgical system stack, and therefore may be connector-free along its bottom surface. In yet another aspect, the head module 202 can be configured to be positioned at an intermediate location within the modular surgical system stack, and therefore may include connectors along both its bottom and top surfaces. The head module 202 can be configured to be accessible via physical controls 411 on the head module ( Figure 4A ) and / or a graphical user interface (GUI) 408 presented on display 206. Figure 4AThe head module 202 is configured to control system-level settings for each module 201 and the components connected to each module. Such settings may include activation of the modular surgical system 200, alarm volume, foot switch settings, settings icons, the appearance or configuration of the user interface, surgeon profiles logged into the modular surgical system 200, and / or the type of surgical procedure being performed. The head module 202 may also be configured to provide communication, processing, and / or power to the modules 201 connected to it.

[0031] Energy module 204 (optionally referred to as generator module) can be configured to generate one or more energy modes for driving electrosurgical instruments and / or ultrasound surgical instruments connected thereto. For example, see reference... Figure 3 The generator 204 is configured to drive multiple surgical instruments 300, 330, and 360. The first surgical instrument is an ultrasonic surgical instrument 300 and includes a handpiece 302 (HP), an ultrasonic transducer 304, a shaft 306, and an end effector 308. The end effector 308 includes a gripping arm 312 and an ultrasonic scalpel 310 acoustically coupled to the ultrasonic transducer 304. The handpiece 302 includes a trigger 314 for operating the gripping arm 312 and a combination of toggle buttons 316a, 316b, and 316c for powering and driving the ultrasonic scalpel 310 or other functions. The toggle buttons 316a to 316c can be configured to power the ultrasonic transducer 304 using the generator 204.

[0032] Generator 204 is also configured to drive a second surgical instrument 330, which is an RF electrosurgical instrument and includes a handpiece 332 (HP), a shaft 334, and an end effector 336. The end effector 336 includes electrodes in gripping arms 338a, 338b and returns through an electrically conductive portion of the shaft 334. These electrodes are coupled to and powered by a bipolar energy source within generator 204. The handpiece 332 includes a trigger 340 capable of manual actuation to operate the gripping arms 338a, 338b and an energy button 342 for actuating an energy switch to power the electrodes in the end effector 336.

[0033] Generator 204 is also configured to drive a third surgical instrument 360, which is a multi-functional surgical instrument 360 and includes a handpiece 362 (HP), a shaft 364, and an end effector 366. The end effector 366 includes an ultrasonic scalpel 368 and a clamping arm 370. The ultrasonic scalpel 368 is acoustically coupled to an ultrasonic transducer 372. The handpiece 362 includes a trigger 374 for operating the clamping arm 370 and a combination of toggle buttons 376a, 376b, and 376c for powering and driving the ultrasonic scalpel 368 or other functions. The toggle buttons 376a to 376c can be configured to power the ultrasonic transducer 372 using generator 204 and the ultrasonic scalpel 368 using a bipolar energy source also included in generator 204. Further aspects of surgical instruments are described in U.S. Patent No. 10,624,691, entitled “TECHNIQUES FOR OPERATING GENERATOR FOR DIGITALLY GENERATING ELECTRICAL SIGNAL WAVEFORMS AND SURGICALINSTRUMENTS”, published on April 21, 2020, the entire contents of which are incorporated herein by reference.

[0034] Pumping module 208 ( Figure 2 The device can be configured to expel fumes, fluids, and / or particles generated by the application of therapeutic energy to tissue by one or more surgical instruments selected from surgical instruments 300, 330, and 360. Example expulsion modules are described in more detail elsewhere herein and in U.S. Patent No. 11,602,393, entitled “SURGICAL EVACUATION SENSING ANDGENERATOR CONTROL,” published March 14, 2023, which is incorporated herein by reference in its entirety. Blow-in module 210 ( Figure 2 It can be configured to blow air or gas into a patient's body cavity to inflate it for diagnostic or surgical purposes, thereby providing better visibility and access during surgery.

[0035] Visualization Module 212 ( Figure 2 This can be configured to interact with visualization devices (i.e., observation devices), and thus provide enhanced visualization capabilities. Example visualization modules and systems are described in more detail in U.S. Patent No. 11,284,963, entitled “METHOD OF USING IMAGING DEVICES IN SURGERY,” published March 29, 2022, which is incorporated herein by reference in its entirety.

[0036] Refer again Figure 2 The modular surgical system 200 may also include various accessories 229 that can be connected to the module 201 for controlling its functions, or are otherwise configured to work in conjunction with the modular surgical system 200. Accessories 229 may include, for example, a single-pedal foot switch 232, a double-pedal foot switch 234, and a trolley 230 for supporting the modular surgical system 200 thereon. Foot switches 232 and 234 may be configured to control the activation or function of, for example, a specific energy mode output by the energy module 204.

[0037] By utilizing modular components, the depicted modular surgical system 200 provides a surgical platform that is optimized for technological availability and can be customized to the needs of facilities and / or surgeons. Furthermore, the modular surgical system 200 supports combined devices (e.g., dual-electrosurgical and ultrasound energy generators) and software-driven algorithms for customized tissue effects. Moreover, the surgical system architecture reduces capital footprint by combining multiple technologies essential for surgical procedures into a single system.

[0038] Various modular components that can be used in conjunction with the modular surgical system 200 may include a monopolar energy generator, a bipolar energy generator, a dual-electric surgical / ultrasound energy generator, a display screen, and various other modules and / or components described elsewhere herein.

[0039] Now for reference Figure 4A In some aspects, head module 202 may include display screen 206, which presents GUI 408 for relaying information about module 201 connected to head module 202. Figure 2Information. In some aspects, the GUI 408 of the display screen 206 can provide a unified control point for all modules 201 constituting a specific configuration of the modular surgical system 200. In another aspect, the head module 202 may not include the display screen 206, or the display screen 206 may be detachably attached (removably attached) to the housing 410 of the head module 202. In such aspects, the head module 202 may be communicatively coupled to an external system configured to display information generated by the modules 201 of the modular surgical system 200. For example, in robotic surgical applications, the modular surgical system 200 may be communicatively coupled to a robotic cart or robotic console configured to display information generated by the modular surgical system 200 to the operator of the robotic surgical system. As another example, the modular surgical system 200 may be communicatively coupled to a mobile display that can be carried or attached to a surgical worker for viewing. In terms of utilizing a user interface that is separate from or otherwise different from the modular surgical system 200, the user interface may be able to wirelessly connect to the modular surgical system 200 as a whole or one or more modules 201 thereon, so that the user interface can display information from the connected module 200 thereon.

[0040] Still referencing Figure 4A The energy module 204 may include a port assembly 412 that includes (provides) a plurality of different ports configured to deliver different energy modes to corresponding surgical instruments that can be connected to these ports (e.g., for example, Figure 3 Surgical instruments 300, 330, 360). In Figure 4A As illustrated in the specific embodiment, port assembly 412 includes a bipolar port 414, a first unipolar port 416a, a second unipolar port 416b, a neutral electrode port 418 (to which a unipolar return pad can be connected), and a combined energy port 420. However, this specific combination of ports is provided only for illustrative purposes, and alternative combinations of ports and / or energy modes may be possible for port assembly 412.

[0041] As noted above, the modular surgical system 200 can be assembled into different configurations. Furthermore, different configurations of the modular surgical system 200 can also be used for different types of surgical procedures and / or different tasks. For example, Figure 4A and Figure 4B A first exemplary configuration of a modular surgical system 200 is illustrated, which includes a head module 202 (including a display screen 206) and an energy module 204 connected together. This configuration can be used for, for example, laparoscopic and open surgical procedures. Figure 4BAs shown, the modular surgical system 200 can be positioned on a trolley 230, thereby enabling the modular surgical system 200 to be easily moved (rolled) around the operating room, for example.

[0042] Figure 5 A second exemplary configuration of a modular surgical system 200 is illustrated, which includes a head module 202 (including a display screen 206), a first energy module 204a, a second energy module 204b, and a drainage module 208 connected together and positioned on a cart 230. In this configuration, the drainage module 208 can drain smoke, fluid, and / or particles generated by surgical instruments powered by the energy modules 204a and 204b.

[0043] Figure 6 This is a block diagram of an example modular surgical system 600 according to at least one aspect of the present disclosure. As illustrated, the modular surgical system 600 includes a head module 202 (including a display screen 206), an energy module 204 stacked below the head module 202 and connected to the head module, an exhaust module 208 stacked below the energy module 204 and connected to the energy module, and an inhalation module 210 stacked below the exhaust module 208 and connected to the exhaust module.

[0044] Head module 202 is configured to monitor, control, power, and provide feedback on the operation of modules within the modular surgical system 600, such as energy module 204, suction module 208, and inhalation module 210. As illustrated, head module 202 includes a controller 620 comprising a processor 622 and a memory 624 storing computer-readable instructions executable by the processor 622 to implement the functions and operations of head module 602. Examples of memory 624 include, but are not limited to, random access memory (RAM), read-only memory (ROM), computer chips, optical discs (e.g., CDs, DVDs, etc.), and magnetic disks (e.g., hard disk drives (HDDs), floppy disks, ZIP drives). ® Disks, magnetic tapes, and solid-state storage devices (e.g., memory cards, "flash" media, etc.). As used herein, the term "computer-readable medium" means any device or system used to store information (e.g., data and instructions) and provide it to processor 622. Examples of computer-readable media include, but are not limited to, optical discs, magnetic disks, magnetic tapes, solid-state media, and servers for streaming media on a network.

[0045] Based on instructions stored in memory 624, processor 622 can be configured to control power and data transmission between head module 202, energy module 204, exhaust module 208, and blow-in module 210 via power interface 608 and data interface 610. For example, head module 202 can transmit various commands to energy module 204, exhaust module 208 (via energy module 204), and blow-in module 210 (via energy module 204 and exhaust module 208) via data interface 610. Such commands can be based on user input received at display 206 or input received by controller 620 from various sensors communicatively coupled to modular surgical system 600, as discussed elsewhere herein.

[0046] As another example, power can be transferred from head module 202 to energy module 204, exhaust module 208 (via energy module 204), and blow-in module 210 (via energy module 204 and exhaust module 208) via power interface 608. For example, head module 202 can receive power from an external power source 660 (referred to herein as "AC mains") such as a wall socket. Head module 202 may include an AC / DC converter 662 that receives AC power from AC mains 660 and converts the AC power to DC power. Controller 202 can then distribute the DC power to energy module 204, exhaust module 208, and blow-in module 210 via power interface 608. Controller 620 may also include a timer 626 for measuring elapsed time. Head module 202 may include a sensor 628, such as a current sensor and / or a power sensor, which is operatively communicateable with controller 620 for measuring current and power along power interface 608.

[0047] like Figure 6 As shown, the energy module 204 may include a controller 680, which includes a processor 682 and a memory 684 storing computer-readable instructions executable by the processor 682 to implement the functions and operations of the energy module 204. The processor 682 and memory 684 may be similar to processor 622 and memory 624, respectively. The controller 680 may receive power from an AC / DC converter 662 along a power interface 608 and may operatively communicate with a controller 620 via a data interface 610.

[0048] Energy module 204 may also include energy generator 670. Energy generator 670 may receive power from AC / DC converter 662 along power interface 608 and may operatively communicate with controller 680, such as via a wired or wireless connection. For example, energy generator 670 may be operable to provide therapeutic energy to one or more surgical instruments (such as surgical instruments 300, 330, 360) via port assembly 412 (such as via bipolar port 414 (FIG. 4), a first unipolar port 416a or a second unipolar port 416b (FIG. 4) or a combined energy port 420 (FIG. 4)). For example, energy generator 670 may be powered using DC power supplied to it from AC / DC converter 662 along power interface 608. Controller 680 may then receive input, such as from controller 620. Based on this input, controller 680 may control energy generator 670 to provide therapeutic energy to one or more surgical instruments coupled to energy module 204 at port assembly 412. The energy generator 670 may include a sensor 672, such as a current sensor and / or a power sensor, which is operatively communicatively connected to the controller 680 for measuring the current and / or power supplied by the energy generator 670. The sensor 672 may also include an impedance sensor for measuring the impedance of tissue grasped by a surgical instrument in a surgical apparatus.

[0049] like Figure 6 As shown, display screen 206 includes a touchscreen 630 coupled to touch controller 632. Touch controller 632 is coupled to controller 620 to read input from touchscreen 630, such as user input. Controller 620 drives LCD display 640 via display / port video output signal 642. Controller 620 is also coupled to audio amplifier 652 to drive one or more speakers 650.

[0050] Surgical air infusion Minimally invasive surgery often requires the creation of a gas-filled cavity to provide the surgeon with sufficient visibility and space to manipulate instruments, such as... Figure 3 Energy delivery devices 300, 330, and 360. The gas filling chamber can utilize a blow-in module (such as blow-in module 210). Figure 2 To generate.

[0051] Figure 7 It is based on at least one aspect of this disclosure Figure 2A schematic diagram of the internal components of the blow-in module 210. The blow-in module 210 may include a blow-in housing 700, which contains a fan or pump 702, a humidifier 703, a heat storage tank 704, a heater 705, and an exhaust mechanism 706, all positioned within the blow-in housing. In some embodiments, the heater 705 may be operable to generate heat, and the heat storage tank 704 is configured to receive and store the heat generated by the heater 705. The stored heat may be used to passively heat the gas moving through the blow-in module 210, as will be described in more detail below. Alternatively, in other embodiments, the heat storage tank 704 may be omitted, and the heater 705 may be operable to actively heat the gas moving through the blow-in module 210. The humidifier 703 may be operable to humidify the gas moving through the blow-in module 210, as will be described in more detail below. A motor 718 is provided to drive the pump 702. When the blow-in module 210 is stacked with the head module 202, it is similar to... Figure 6 As shown in the arrangement, the motor 718, humidifier 703, and heater 705 can receive power via power interface 608.

[0052] The blow-in module 210 defines a flow path 708 (partially shown in dashed lines) that extends through the blow-in housing 700 and has an inlet port 710 and an outlet port 712. A pump 702, a humidifier 703, a heat reservoir 704, and an exhaust mechanism 706 are arranged sequentially in series within the flow path 708, passing through the blow-in housing 700 between the inlet port 710 and the outlet port 712. The outlet port 712 can be fluidly coupled to a cannula that is in fluid communication with a patient's internal lumen (e.g., the patient's peritoneal cavity).

[0053] Inlet port 710 can be fluidly connected to gas source 720 via conduit 722 (pipe). As an example, gas source 720 may contain gases such as carbon dioxide (CO2), nitrous oxide (N2O), helium, oxygen, air, xenon, argon, or nitrogen (N2).

[0054] Pump 702 is configured to generate a pressure difference in flow path 708 through mechanical action. This pressure difference draws gas 714 from gas source 720 through conduit 722 to inlet port 710 and along flow path 708. After moving through humidifier 703 and heat storage tank 704, gas 714 can be considered “heated / humidified” gas 716 (referred to herein as “blow-in” gas 716), which can continue through flow path 708 and exhaust mechanism 706, ultimately exiting (emitting) through outlet port 712. Exhaust mechanism 706 can control the rate, direction, and / or other properties of the blow-in gas 716 exiting blow-in module 210 at outlet port 712.

[0055] The flow path 708 through the blow-in module 210 may be formed by a pipe or other conduit that substantially contains the fluid moving through the flow path 708 and / or isolates the fluid moving through the flow path from the fluid outside the flow path 708 (the surrounding environment).

[0056] Surgical smoke extraction As presented in this article, energy devices (such as...) Figure 3 Energy delivery devices 300, 330, 360 deliver mechanical (e.g., ultrasound) and / or electrical (e.g., RF) energy to target tissue for therapeutic purposes (e.g., cutting tissue, cauterizing blood vessels, and / or coagulating tissue within and / or near the target tissue). Cutting, cauterizing, and / or coagulating tissue can result in the release of fluids and / or particles into the air. Such fluids and / or particles released during surgical procedures can constitute a smoke, which may include, for example, carbon particles and / or other particles suspended in the air. In other words, the fluid may include smoke and / or other fluid substances.

[0057] Approximately 90% of endoscopic and open surgical procedures generate some level of smoke. This smoke can be unpleasant to clinicians, assistants, and / or patients, may hinder the clinician's view of the surgical site, and in some cases may be unhealthy to inhale. For example, smoke generated during electrosurgery can contain toxic chemicals including acrolein, acetonitrile, acrylonitrile, acetylene, alkylbenzene, benzene, butadiene, butene, carbon monoxide, cresol, ethane, ethylene, formaldehyde, free radicals, hydrogen cyanide, isobutylene, methane, phenol, polycyclic aromatic hydrocarbons, propene, propylene, pyridine, pyrrole, styrene, toluene, and xylene, as well as dead and living cell material (including blood fragments) and viruses. Some substances identified in surgical smoke have been classified as containing known carcinogens. It is estimated that one gram of tissue cauterized during electrosurgery is equivalent to the toxins and carcinogens of six unfiltered cigarettes. Additionally, exposure to smoke released during electrosurgery has been reported to cause eye and lung irritation for healthcare workers.

[0058] In addition to the toxicity and odor associated with the materials in surgical smoke, the size of the particles in surgical smoke can be harmful to the respiratory systems of clinicians, assistants, and / or patients. In some cases, the particles can be very small, and in some cases, repeated inhalation of very small particles can lead to acute and chronic respiratory illnesses.

[0059] Many electrosurgical systems employ surgical evacuation systems that inhale and capture fumes generated during surgery and direct the captured fumes through filters and exhaust ports away from clinicians and / or patients. For example, evacuation systems (such as evacuation module 208) Figure 2 A system can be configured to remove smoke generated during electrosurgery. Such a system can be called a "smoke extraction system," but it can also be configured to remove more than just smoke from the surgical site.

[0060] Throughout this disclosure, the “smoke” expelled by the extraction system is not limited to mere smoke. Rather, the smoke extraction system disclosed herein can be used to extract a variety of fluids, including liquids, gases, vapors, fumes, steam, or combinations thereof. The fluid may be of biological origin and / or may be introduced to the surgical site from an external source during surgery. Fluids may include, for example, water, saline, lymph, blood, exudate, and / or purulent discharge. Furthermore, the fluid may include particles or other substances (e.g., porous materials or fragments) expelled by the extraction system. For example, such particles may be suspended in the fluid.

[0061] Figure 8 It is based on at least one aspect of this disclosure Figure 2 A schematic diagram of the internal components of the exhaust module 208. The exhaust module 208 includes an exhaust housing 801, within which a fan or pump 804 and a filter 800 are positioned. Smoke drawn into the exhaust housing 801 travels to the filter 800, and as the smoke moves through (crosses) the filter 800, harmful toxins and pungent odors are filtered out. The filtered air 814 can then exit the exhaust module 208 as exhaust gas.

[0062] The suction module 208 defines a flow path 806 (shown in dashed lines) that extends through the suction housing 801 and has an inlet port 808 and an outlet port 810. A filter 800, a pump 804, and a venting mechanism 802 are arranged sequentially in series within the flow path 806, passing through the suction housing 801 between the inlet port 808 and the outlet port 810. The inlet port 808 can be fluidly coupled to a suction catheter 702, which may include a distal catheter opening capable of being positioned at a surgical site.

[0063] Pump 804 is configured to generate a pressure differential in flow path 806 by mechanical action. This pressure differential is configured to draw smoke 812 from the surgical site into inlet port 808 and along flow path 806. After passing through filter 800, smoke 812 can be considered “filtered” smoke or air 814 (referred to herein as “filtered air 814”), which can continue through flow path 806 and eventually be discharged (emitted) through outlet port 810.

[0064] As illustrated, flow path 806 may include a first zone 816 and a second zone 818. The first zone 816 is located upstream of pump 804; the second zone 818 is located downstream of pump 804. Pump 804 is configured to generate a vacuum and otherwise pressurize the fluid in flow path 806 to drive the fluid from the first zone 816 to the second zone 818 via pump 804. Motor 820 drives pump 804. When pumping module 208 is stacked with head module 202, it is similar to... Figure 6 As shown in the arrangement, the motor 820 can receive power via the power interface 608. The exhaust mechanism 802 is a mechanism that can control the speed, direction, and / or other properties of the filtered air 814 leaving the exhaust module 208 at the outlet port 810.

[0065] The flow path 806 through the exhaust module 208 may be constructed of a pipe or other conduit that substantially contains the fluid moving through the flow path 806 and / or isolates the fluid moving through the flow path from fluids outside the flow path 806 (the surrounding environment). For example, a first region 816 of the flow path 806 may include a pipe through which the flow path 806 extends between the filter 800 and the pump 804. A second region 818 of the flow path 806 may also include a pipe (conduit) through which the flow path 806 extends between the pump 804 and the exhaust mechanism 802. The flow path 806 also extends through the filter 800, the pump 804, and the exhaust mechanism 802, such that the flow path 806 extends continuously from the inlet port 808 to the outlet port 810.

[0066] In operation, smoke 812 can flow into filter 800 after passing through inlet port 808, and can be pumped by pump 804 through flow path 806, so that smoke 812 is drawn into filter 800. Then, filtered air 814 discharged from filter 800 can be pumped through exhaust mechanism 802 and discharged from outlet port 810 of exhaust module 208. The filtered air 814 leaving exhaust module 208 at outlet port 810 is exhaust gas and can be composed of gas that has passed through exhaust module 208. Additional information about exhaust module 208 is described in U.S. Patent No. 11,602,393, entitled “SURGICAL EVACUATION SENSING AND GENERATOR CONTROL”, published March 14, 2023, which is incorporated herein by reference in its entirety.

[0067] According to embodiments of this disclosure, the exhaust module 208 may further include a plurality of sensors 820a, 820b, 820c, 820d positioned along the flow path 806 for measuring one or more parameters associated with the smoke 812 and / or filtered air 814 flowing along the flow path 806. When the exhaust module 208 is in a stacked configuration with the head module 202, such as when in a stacked configuration... Figure 6 The configuration shown, for example, allows sensors 820a to 820d to operatively communicate with controller 620, such as via data interface 610. Figure 6 And it can be accessed via power interface 608 ( Figure 6 The controller 620 receives power from the head module 202. The controller 620 can receive measurement results from sensors 820a to 820d and control various operations of the modular surgical system based on these measurement results. For example, in some embodiments, the controller 620 can control the speed of the motor 820 based on the received measurement results.

[0068] One or more of sensors 820a to 820d may include flow sensors for measuring the flow rate of smoke 812 / filtered air 814 along flow path 806, such as, for example, the flow rate entering inlet port 808 (sensor 820a), the flow rate through first zone 816 (sensor 820b), the flow rate through second zone 818 (sensor 820c), and / or the flow rate exiting outlet port 810 (sensor 820d). Alternatively or as a supplement thereto, one or more of sensors 820a to 820d may include pressure sensors for measuring the pressure of smoke 812 / filtered air 814 along flow path 806, such as, for example, at inlet port 808 (sensor 820a), first zone 816 (sensor 820b), second zone 818 (sensor 820c), and / or at outlet port 810 (sensor 820d). In some implementations, sensors 820a to 820d can be used by controller 620 to measure pressure differences along flow path 806, such as pressure differences across filter 800, using first sensor 820a and second sensor 820b. Pumping module 208 may include a combination of both flow sensors and pressure sensors.

[0069] Use surgical checklists to predict smoke extraction needs. Surgical checklists can be used to guide clinicians and other operating room (OR) staff in performing surgical procedures. These checklists can include the steps to be performed for a given surgical procedure. Based on the given steps of the surgical procedure, the smoke requirement for the procedure can be anticipated.

[0070] Figure 9 This is a block diagram of an example modular surgical system 900 according to at least one aspect of the present disclosure. As illustrated, the modular surgical system 900 includes a head module 202, a display 206 coupled to the head module 202, an energy module 204 stacked below and coupled to the head module 202, and an exhaust module 208 stacked below and coupled to the energy module 204. For example, the modular surgical system 900 may include additional modules, such as the air intake module 208, as described elsewhere herein. The modular surgical system 900 may be similar in some respects to... Figure 6 The modular surgical system 600, and therefore can be best understood by reference, where similar numbers will correspond to similar parts which will not be described in detail again.

[0071] Display 206 may include a touchscreen 630, which is coupled to the controller 620 of head module 210 to read input from touchscreen 630, such as user input. Controller 620 may read input based on user input and / or stored in memory 624 of controller 620. Figure 6The data in memory 624 drives the LCD display 640 of the screen 206. The user can provide input to the touchscreen 630 indicating the type of surgery to be performed. The controller 620 can then access the data from memory 624. Figure 6 The controller 620 retrieves the steps associated with the type of surgery to be performed. The controller 620 can then display the associated steps of the surgical procedure to be performed on the LCD display 640.

[0072] For example, continue to refer to Figure 9 The user can provide input to the touchscreen 630, thereby notifying the controller 620 to perform a gastrectomy. The controller 620 can retrieve the data from the memory 624. Figure 6 The system retrieves steps associated with gastrectomy and displays these steps as interactive widgets on display screen 206. These steps may include: patient preparation (widget 902); establishing access points to the patient, such as via a cannula (widget 904); and utilizing surgical devices 300, 330, 360 connected to power module 204. Figure 3 A surgical device (component 906) is used to free the patient's stomach; such as surgical devices 300, 330, 360 connected to the power module 204. Figure 3 A surgical device is used to separate the stomach from the rest of the stomach (component 908); remove the separated stomach portion from the patient (component 910); suture the cutting line to the rest of the stomach (component 912); and close the patient (component 914).

[0073] Clinicians and other OR staff can navigate through surgical procedures by providing input to the touchscreen 630. OR staff can interact with widgets 902, 904, 906, 908, 910, 912, and 914 based on the associated steps of the procedure being performed or about to begin. For example, as... Figure 9 As shown, the OR staff has interacted with components 902 and 904 (providing input to these components) to signal to controller 620 that the patient is ready (via component 902) and that a pathway point has been established (via component 904), and that the next step in the procedure is to detach the stomach (component 906). Therefore, controller 620 can know which step of the surgery is about to occur and can thus anticipate the upcoming smoke requirement, as will be discussed in more detail below.

[0074] In addition to the above, or in an alternative, controller 620 may use a context-aware module to identify surgical procedures, as described in more detail in U.S. Patent No. 11,424,027, entitled “METHOD FOR OPERATING SURGICAL INSTRUMENT SYSTEMS,” published August 23, 2022, the entire contents of which are incorporated herein by reference. For example, controller 620 may receive instructions from energy module 204 regarding energy devices such as surgical instruments 300, 330, 360 (…). Figure 3 The controller 620 can use data from the powered surgical instruments in the procedure to infer that the clinician is mobilizing the patient's stomach. The controller 620 can cross-reference the received data with the retrieved steps of the surgical procedure to determine which point in the procedure (i.e., after the pathway formation step (component 904) is completed) corresponds to the mobilization step.

[0075] The controller 620 can use known steps of the surgical procedure to set parameters for one or more modules (such as the drainage module 208) in the modular surgical system 900. For example, in a gastrectomy, when the surgeon typically makes a large "cut" of thick tissue using surgical instruments, the free stomach (component 906) is expected to generate a first amount of smoke. When the surgeon moves to the dissected stomach (component 908), a second amount of smoke, less than the first amount, is expected to be generated because the tissue is being cut into smaller, more fragmented pieces using surgical instruments.

[0076] Figure 10 It is a control based on at least one aspect of this disclosure Figure 9 A schematic flowchart illustrating an example method 1000 of a modular surgical system 900. Method 1000 can be embodied in a controller 620 ( Figure 9 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input provided to controller 620 (such as on touchscreen 630) Figure 9 (to be executed at) (place).

[0077] refer to Figure 9 and Figure 10 Method 1000 may include receiving a first input indicating the type of surgical procedure, as at step 1002. For example, a user may provide input to controller 620 via touchscreen 630, thereby informing controller 620 that a type of surgical procedure, such as a gastrectomy, will be performed.

[0078] Method 1000 may optionally include a step of displaying on a monitor an association with the type of surgical procedure, as at step 1004. For example, based on receiving a first input, controller 620 can retrieve data from memory 624 (…). Figure 6 The procedure retrieves the steps associated with the type of surgery and displays these steps on display screen 206 as interactive widgets, such as widgets 902 to 914, thereby informing clinicians and other OR staff of the steps to be performed for the selected type of surgery.

[0079] Method 1000 may also include receiving a second input instructing a first step of the surgical procedure, as at step 1006. For example, controller 620 may receive the input based on user interaction with one of the displayed widgets 902 to 914. Alternatively, as discussed above, controller 620 may automatically receive input from a context-aware module. As an example, the first step of the surgical procedure may be patient preparation (widget 902), establishing a pathway point within the patient (widget 904), or freeing the stomach (widget 906).

[0080] Method 1000 may also include setting a first motor speed for the pumping motor, as at step 1008. For example, the memory 624 of the controller 620 ( Figure 6 This may include a lookup table that links the steps of the surgical procedure to the suction motor 820. Figure 8 The controller 620 can retrieve a first motor speed of the suction motor 820 from memory 624 based on a second input indicating the first step of the surgical procedure. The controller 620 can then set the motor speed of the suction motor 820 as the first motor speed. The selected motor speed may be sufficient to suction the amount of smoke expected to be generated during the free movement of the gastric tissue. The controller 620 can set the first motor speed, for example, via power interface 608. Figure 6 (This provides power to the pumping motor 820.)

[0081] Method 1000 may also include receiving a third input instructing a second step of the surgical procedure, as at step 1010. For example, controller 620 may receive input from a context-aware module based on user interaction with one of the displayed widgets 902 to 914 or automatically, as discussed above. The second step of the surgical procedure may, for example, be the dissection of the stomach to perform a gastrectomy.

[0082] Method 1000 may further include adjusting the first motor speed to a second motor speed, as at step 1012. For example, controller 620 may retrieve the second motor speed of the suction motor 820 from a lookup table in memory 624 based on receiving a third input instructing a second step of the surgical procedure. Controller 620 may then adjust the motor speed of the suction motor 820 from the first motor speed to a second motor speed, which may be different from (less than or greater than) the first motor speed. For example, the second motor speed may be slower than the speed used for freeing the stomach, because less smoke is expected to be generated as the stomach is dissected. Controller 620 may adjust the second motor speed, such as via power interface 608 (… Figure 6 (This provides power to the pumping motor 820.)

[0083] Method 1000 may further include receiving a fourth input and adjusting the motor speed to a user-selected motor speed based on the fourth input. For example, after the controller 620 has already set a first motor speed (step 1008) or a second motor speed (step 1012), the user may wish to increase or decrease the motor speed. The user can provide input to the controller 620 via the touchscreen 630, thereby notifying the controller 620 that the pumping motor 820 needs adjustment. Figure 8 The controller 620 can adjust the motor speed based on the received user input. This adjustment can be made from a pre-set motor speed (such as a first motor speed at step 1008, or a second motor speed at step 1012) to a user-selected motor speed. Therefore, the controller 620 can set the motor speed of the suction motor 820 based on the determined steps of the surgical procedure, and then adjust the set motor speed based on user input.

[0084] Therefore, by knowing the type and steps of the surgical procedure being performed, the controller 620 can establish an initial setpoint at the start of the case based on the most common settings, and secondly, it can adjust the settings for each surgical step to take into account changes in device use and the resulting smoke. Actively adjusting the motor speed of the exhaust motor 820 can also increase the efficiency of the filter 800 by customizing the smoke extraction and using only the necessary flow rate instead of a one-size-fits-all approach. Figure 8 ) lifespan.

[0085] The smoke extraction rate is determined based on tissue classification or input from the visualization module. Refer again Figure 9 When different tissue types are powered by energy devices such as surgical instruments 300, 330, 360 ( Figure 3When a surgical instrument in a modular surgical system 900 performs surgery (treatment), it typically generates varying levels of smoke. For example, liver tissue is expected to generate dense, moist smoke when it is treated, thus requiring a first (high) flow rate and a first (long) time from the drainage module 208. On the other hand, isolated thin blood vessels (such as the thyroid trunk) are expected to generate a light aerosol-like smoke mist when they are treated, thus requiring a second (low) flow rate and a second (short) time from the drainage module 208 that is less than the first (high) flow rate. Therefore, the controller 620 can set parameters for various surgical modules (such as the drainage module 208) within the modular surgical system 900 based on the determined (known) type of tissue being operated on by the surgical instrument.

[0086] Surgical instruments (such as surgical instruments 300, 330, 360) Figure 3 During the initial period when a surgical module (of the surgical instrument) is powered while interacting with tissue, three radio frequency (RF) electrical parameter measurements can be performed. These electrical parameters may include initial RF impedance, minimum RF impedance, and the amount of time during which the RF impedance slope is approximately zero. The surgical instrument may be coupled to an energy module 204, which may collect these measurements, for example, via a data interface 610, and send these measurements to a controller 620 of the head module 202. Based on this data, the controller 602 may, for example, use a support vector machine (SVM) or another classification algorithm to classify (determine) the type of tissue with which the surgical instrument is interacting. More information on tissue classification using measurements from the surgical instrument can be found in U.S. Patent No. 11,298,148, entitled “LIVETISSUE CLASSIFICATION USING ELECTRICAL PARAMETERS,” published April 12, 2022, which is incorporated herein by reference in its entirety.

[0087] Figure 11 It is a control based on at least one aspect of this disclosure Figure 9 A schematic flowchart of example method 1100 of the modular surgical system 900. Method 1100 can be embodied in the controller 620 ( Figure 9 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input provided to controller 620 (such as on touchscreen 630) Figure 9 (to be executed at) (place).

[0088] refer to Figure 9 and Figure 11Method 1100 may include receiving input from a surgical device, as at step 1102. In one aspect, the surgical device may be a surgical instrument, such as surgical instruments 300, 330, 360 (…). Figure 3 The surgical device may include a surgical instrument, and the energy module 204 may receive input based on the interaction between the surgical instrument and tissue. This input may include initial RF impedance, minimum RF impedance, or the amount of time during which the RF impedance slope is approximately zero, or a combination thereof. The controller 620 may receive these inputs from the energy module 204, such as via a data interface 610. Alternatively, the surgical device may include a camera, and a visualization module 212 (… Figure 2 It can receive input (i.e., imaging data) from a camera. Imaging data can include real-time images of surgical sites, including tissues, within the patient's body.

[0089] Method 1100 may further include determining the tissue type, as at step 1104. In one aspect, based on input received from the surgical instrument / energy module 204, the controller 620 may use a support vector machine (SVM) or another classification algorithm to determine the tissue type. In another aspect, based on input received from the camera / visualization module 210, the controller 620 may, for example, determine the tissue type by comparing real-time visualized tissue with data stored in memory 624. Figure 6 The images in the patent can be compared or any suitable detection method described in more detail in U.S. Patent No. 11,284,963, entitled “METHOD OF USING IMAGING DEVICES IN SURGERY”, published on March 29, 2022, which is incorporated herein by reference in its entirety.

[0090] Method 1100 may also include setting the motor speed of the pumping motor, as at step 1106. For example, the memory 624 of the controller 620 ( Figure 6 ) may include a lookup table that associates the type of tissue with the pumping motor 820 ( Figure 8 The controller 620 can retrieve the motor speed of the pumping motor 820 from the memory 624 based on the determined tissue type. The controller 620 can then set the pumping motor 820 to the retrieved motor speed, and such as via the power interface 608 ( Figure 6 The set motor speed powers the pumping motor 820.

[0091] Method 1100 may optionally further include determining the time for powering the pumping motor at the motor speed, as at step 1108. Memory 624 ( Figure 6 The lookup table in ) can also include the selected motor speed for the pumping motor 820 ( Figure 8The controller 620 can retrieve the motor speed of the pumping motor 820 from the memory 624 based on the determined tissue type and the time amount of power supplied to the pumping motor 820. Figure 8 The amount of time that energy is supplied.

[0092] Method 1100 may optionally further include powering the pumping motor at a motor speed, as at step 1110, and de-energizing the pumping motor based on the amount of time elapsed, as at step 1112. For example, based on the controller 620 determining in step 1108 that the pumping motor 820 ( Figure 8 The amount of power supplied by the controller 620 can be provided, for example, via the power interface 608. Figure 6 The controller 620 supplies power to the pumping motor 820 at a set motor speed. The controller 620 can also utilize, for example, a timer 626 (…). Figure 6 The time elapsed is measured, and the pumping motor 820 is activated based on the elapsed time reaching a predetermined time. Figure 8 Power outage.

[0093] In some applications, method 1100 may also include receiving a second input and adjusting the motor speed to a user-selected speed based on the second input. For example, after the controller 620 has already set the motor speed (step 1106), the user may wish to increase or decrease the motor speed. The user can provide input to the controller 620 via the touchscreen 630, thereby notifying the controller 620 that the pumping motor 820 needs adjustment. Figure 8 The controller 620 can then adjust the set motor speed to the user-selected motor speed based on the received user input. Therefore, the controller 620 can set the motor speed of the pumping motor 820 based on the determined tissue type, and then adjust the set motor speed based on user input.

[0094] Therefore, the controller 620 can be operated to set the motor speed of the exhaust motor to take into account the smoke expected to be generated for a given tissue type. Actively adjusting the motor speed of the exhaust motor 820 can also increase the efficiency of the filter 800 by customizing the smoke extraction and using only the necessary flow rate instead of a one-size-fits-all approach. Figure 8 ) lifespan.

[0095] Use system feedback to determine filter life. Over time, the filters in the smoke exhaust system (such as the exhaust module 208) Figure 8 Filter 800 in ) Figure 8The filter 800 may become filled with airborne particles, and its effectiveness may decrease accordingly, requiring timely replacement to maintain optimal performance of the exhaust module 208. Current methods for determining when to replace the filter 800 may not adequately quantify the amount of particles that have passed through it, potentially leading to premature or delayed replacement. Therefore, improved systems and methods are needed for determining when to replace filters in the exhaust module.

[0096] refer to Figure 8 and Figure 9 The controller 620 can receive multiple inputs and calculate (determine) the theoretical amount of smoke captured by the filter 800 during surgical procedures based on these inputs. The multiple inputs may include surgical instruments (such as surgical instruments 300, 330, 360) coupled to the energy module 204. Figure 3 The controller 620 can use the theoretical amount of smoke captured by the filter 800 to calculate (determine) the remaining lifespan of the filter 800. The controller 620 can then correlate the remaining lifespan with the amount of smoke that can be stored in memory 624. Figure 6 The thresholds in the data are compared to determine whether filter 800 can be used in subsequent surgical procedures or whether the filter should be replaced.

[0097] Figure 12 It is a control based on at least one aspect of this disclosure Figure 9 A schematic flowchart of example method 1200 of the modular surgical system 900. Method 1200 can be embodied in the storage of data in controller 620. Figure 9 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input provided to controller 620 (such as on touchscreen 630) Figure 9 (to be executed at) (place).

[0098] refer to Figure 9 and Figure 12 Method 1200 may include receiving a first input indicating the type of surgical instrument, as at step 1202. For example, controller 620 may be based on surgical instruments (such as surgical instruments 300, 330, 360, etc.). Figure 3The method 1200 may also include receiving a second input, such as at step 1204, which is a surgical instrument connected to the power module 204 or based on input provided by the user to the controller 620 via the touchscreen 630 of the display 206. For example, the controller 620 may receive the second input based on input provided by the user to the controller 620 via the touchscreen 630 or based on input from a context-aware module, as described in more detail in U.S. Patent No. 11,424,027 entitled “METHOD FOROPERATING SURGICAL INSTRUMENT SYSTEMS”, published August 23, 2022, the contents of which are incorporated herein by reference in their entirety. For example, the type of surgery may be a general type of surgery, such as open or laparoscopic surgery, or a specific type of surgery, such as gastrectomy.

[0099] Method 1200 may further include determining the theoretical smoke generation rate of surgical instruments during this type of surgical procedure, as at step 1206. Memory 624 ( Figure 6 This could include a lookup table that associates the type of surgical instrument and the type of surgical procedure with the theoretical smoke generation rate. For example, the lookup table could include a first surgical instrument, such as a monopolar pen, intended to generate a first theoretical smoke rate for a first type of surgical procedure (e.g., laparoscopic surgery) and a second theoretical smoke rate different from the first theoretical smoke rate for a second type of surgical procedure (e.g., open surgery). An example monopolar pen is shown and described in U.S. Patent Application Publication No. 2010 / 0036373, published February 11, 2010, entitled “ELECTROSURGICAL SYSTEM HAVING A SENSOR FOR MONITORING SMOKE AND AEROSOLS,” the contents of which are incorporated herein by reference in their entirety.

[0100] The lookup table may also include second surgical instruments, such as RF surgical instruments 330 ( Figure 3 ), such as being expected to generate a third theoretical smoke rate for type I surgery and a fourth theoretical smoke rate different from the third theoretical smoke rate for type II surgery. The lookup table may also include third surgical instruments, such as the multi-functional surgical instrument 360 (…). Figure 3 ), such as being expected to generate a fifth theoretical smoke rate for the first type of surgery and a sixth theoretical smoke rate different from the fifth theoretical smoke rate for the second type of surgery.

[0101] Method 1200 may further include receiving a third input indicating the amount of time during which surgical instruments are powered during this type of surgical procedure, as at 1208. For example, controller 620 may receive input from energy module 204 based on the fact that surgical instruments are powered to treat tissue. Based on the received input, controller 620 may use timer 626 ( Figure 6 The controller 620 can then receive another input at a later time indicating that the surgical instrument should no longer be powered to treat the tissue. Based on the received input indicating that the surgical instrument should no longer be powered, the controller 620 can stop the timer 626. The controller 620 can repeat this process (starting and stopping the timer 626) whenever the surgical instrument is activated / deactivated to measure the total amount of time the surgical instrument is powered during the surgical procedure.

[0102] Method 1200 may also include determining the theoretical amount of smoke generated based on the theoretical smoke generation rate and the amount of time, as at step 1210. For example, controller 620 may calculate (determine) the theoretical smoke generation rate by multiplying the theoretical smoke generation rate determined at step 1206 by the amount of time the surgical instrument has been powered, as determined at step 1208.

[0103] Method 1200 may further include determining the remaining lifespan of the filter based on the determined theoretical amount of smoke generated, as at 1212. More specifically, controller 620 may be located in memory 624 ( Figure 6 The filter 800 of the storage and extraction module 208 is located in the storage and extraction module. Figure 8 The filter life value is set by the user at the touchscreen 630 to the controller 620, or it can be automatically set by the controller 620 based on the placement of the filter 800 into the suction module 208. Based on the fact that surgical instruments are powered during surgery, the controller 620 can power the motor 820 of the suction module 208. Figure 8 Power is supplied to draw the smoke generated by surgical instruments through a filter 800 ( Figure 8 (as described elsewhere in this document). The controller 620 can use the determined theoretical amount of smoke generated to track the lifespan of the filter 800 over time.

[0104] Controller 620 can access memory 624 ( Figure 6 The controller 620 retrieves the filter life value and subtracts the determined theoretical amount of smoke generated from it to generate a remaining filter life value, which can be written (recorded) in memory 624. The controller 620 can retrieve the remaining filter life value as a starting point when reducing the theoretical amount of smoke generated for subsequent surgical procedures.

[0105] Method 1200 may further include comparing the remaining filter lifetime with a threshold, as at step 1214. For example, controller 620 may retrieve a threshold from memory 624 to compare with a remaining filter lifetime value as determined at step 1212. Controller 620 may also perform actions based on this comparison. For example, method 1200 may further include allowing surgical instruments to be powered for subsequent surgical procedures based on a remaining filter lifetime value being at or greater than a threshold, as at step 1216. Alternatively, method 1200 may include preventing surgical instruments from being powered for subsequent surgical procedures based on a remaining filter lifetime value being less than a threshold, as at step 1218, and / or generating an alarm, as at step 1220. In such embodiments, controller 620 may prevent AC mains power 660 ( Figure 6 ) provides power to surgical instruments. The controller 620 can also generate alarms to notify the user that the filter 800 should be replaced. Figure 8 Alarms can be sent via LCD640 ( ). Figure 6 Visual alarm or via speaker 650 ( Figure 6 (audio alarm)

[0106] Therefore, the aforementioned method employs system feedback, such as instrument parameters (e.g., type of surgical instrument), operating environment (e.g., open or laparoscopic surgery), and activation time of the surgical instrument, to calculate the theoretical smoke volume. This theoretical smoke volume can then be correlated with a percentage of the remaining filter lifespan. This remaining filter lifespan value can be written to memory 624 ( Figure 6 ), and then used in future surgical procedures (quote) to track filter lifespan over time. This method can extend the filter lifespan by 800 ( ) when using actual inputs and parameters from surgical procedures. Figure 8 The lifespan of a filter should be measured by its lifespan, not just by the time it is used.

[0107] Final draw mode Figure 13 This is a block diagram of another example of a modular surgical system 1300 according to at least one aspect of this disclosure. The modular surgical system 1300 may be similar in some respects to... Figure 6 The modular surgical system 600 is therefore best understood with reference to it. As illustrated, for example, the modular surgical system 1300 includes a head module 202 having a controller 620, a display 206 coupled to the head module 202, an inhalation module 210 stacked below and coupled to the head module 202, and an exhaust module 208 stacked below and coupled to the inhalation module 210. For example, the modular surgical system 1300 may include additional modules, such as an energy module 204, as described elsewhere herein.

[0108] The modular surgical system 1300 may also include an insufflation cannula 1304, which is inserted into the patient's body cavity 1302 and is in fluid communication with the insufflation module 210 to receive insufflated gas 716 therefrom. Figure 7 The modular surgical system 1300 may also include a drainage cannula 1306, which is inserted into the patient's body cavity 1302 and is in fluid communication with the drainage module 208 to aspirate (drain) smoke 812 from the patient's body cavity 1302. Figure 8 ).

[0109] The modular surgical system 1300 may also include a pressure sensor 1308 for sensing pressure within the patient's body cavity 1302 and a blow-in gas 716 for measuring the flow of gas from the blow-in module 210 into the patient's body cavity 1302. Figure 7 The flow sensor 1310 measures the flow rate of the airway. As illustrated, by way of example, the pressure sensor 1308 and the flow sensor 1310 can be coupled to the intubation cannula 1304, but can alternatively be located at any suitable location within the modular surgical system 1300, such as at the intubation module 210 or along the flow line between the intubation module 210 and the intubation cannula 1304. The controller 620 can be connected, for example wirelessly or wiredly, such as along the data interface 610 (…). Figure 6 The pressure measurement results and flow measurement results are received from the pressure sensor 1308 and the flow sensor 1310, respectively.

[0110] In some cases, it may be desirable to purge gas from the patient's body cavity 1302 at the end of a surgical procedure, such as before removing the intubation cannula 1304 and the drainage cannula 1306. Therefore, the controller 620 can display the final drainage component 1312 on the touchscreen 630, which the clinician can interact with (by pressing the final drainage component) when final drainage of the patient's body cavity 1302 is required.

[0111] Figure 14 It is a control based on at least one aspect of this disclosure Figure 13 A schematic flowchart of an example method 1400 for a modular surgical system 1300. Method 1400 can be embodied in a controller 620 ( Figure 13 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input provided to controller 620 (such as on touchscreen 630) Figure 13 (to be executed at) (place).

[0112] refer to Figure 13 and Figure 14Method 1400 may include receiving input indicating a final drainage request, as at step 1402. For example, when final drainage of gas from the patient's body cavity 1302 is required, the user may interact with the final drainage component 1312 at the end of the surgical procedure (e.g., by pressing the final drainage component). Controller 620 may receive input based on user interaction with the final drainage component 1312.

[0113] Method 1400 may also include determining the initial blow-in volume (V I ), as at step 1404. For example, controller 620 may measure, for example, the amount of gas 716 blown into the patient's body cavity 1302 at the start of surgical procedure. Figure 7 The controller 620 can monitor the rate (e.g., in cm⁻¹) of the inhaled gas supplied to the patient's body cavity 1302 via the flow sensor 1310. 3 The controller 620 measures the time elapsed (e.g., in seconds) during which the blown gas 716 is delivered to the patient's body cavity 1302. The controller 620 can calculate the initial blown volume V by multiplying the determined rate of the blown gas by the elapsed time. I The controller 620 can control the initial blow-in volume V. I Stored in memory 624 ( Figure 6 In, and subsequently retrieve the initial blow-in volume V as needed. I .

[0114] Method 1400 may also include determining the initial blow-in pressure (P). I (e.g., at step 1406). For example, controller 620 may measure the initial inhalation pressure P via pressure sensor 1308, such as at the start of surgery. I The controller 620 can set the initial blow-in pressure P. I Stored in memory 624 ( Figure 6 In, and then retrieve the initial blow-in pressure P as needed. I .

[0115] Method 1400 may also include determining the final blow-in pressure (P). F (e.g., at step 1408). For example, controller 620 may measure the final blow-in pressure P via pressure sensor 1308, such as at the end of a surgical procedure or based on user interaction with the final expulsion assembly 1312. F The controller 620 can adjust the final blow-in pressure P. F Stored in memory 624 ( Figure 6 In, and then retrieve the final blow-in pressure P as needed. F .

[0116] Method 1400 may also include calculating the final blow-in volume (V F (e.g., at step 1410). For example, controller 620 can use the following expression to calculate the final blow-in volume V. F This expression can be stored in memory 624 ( Figure 6 )middle: V F = P I V I / P F Method 1400 may also include using an aspirator module to aspirate from the patient's body cavity the final blown-in volume V. F As in step 1412. In one aspect, the controller 620 can base its calculation on the final blow-in volume V. F The known (set) motor current (speed) of motor 820 is used to estimate the speed of motor 820 in pumping module 208. Figure 8 The amount of time required to supply power. Controller 620 can then power motor 820 to pump out the final blown-in volume V from patient's body cavity 1302. F The estimated time is reached. On the other hand, the controller 620 can power the motor 820, and via the flow sensor 820a ( Figure 8 )Measure the smoke 812 from the patient's body cavity 1302 ( Figure 8 ) and gas flow rate, and use timer 626 ( Figure 6 The controller 620 measures the elapsed time based on the product of the measured rate and the measured time. The controller can then determine whether the final blow-in volume V approaches, reaches, or exceeds the final blow-in volume. F To disconnect the power to motor 820.

[0117] Therefore, the aforementioned systems and methods can reduce the amount of surgical fumes exposed to OR staff because the final volume of fumes in the patient's body is removed before the cannula is removed from the patient.

[0118] Operating room (OR) staff (such as nurses) often have to manually adjust multiple settings of insulators and aspirators, such as run time, pressure, or flow rate, during surgical procedures as devices are changed and / or different surgical steps are performed. Systems and methods for preemptively or automatically adjusting settings can provide more efficient surgery with less technical support.

[0119] Refer again Figures 6 to 8The controller 620 can collect data from multiple sources and set the motor speeds of the suction motor 820 and / or the blow-in motor 718 based on the collected data. The data collected by the controller 620 may include the type of cannula inserted into the patient, the type of cannula attachment, and the type of device connected to the energy module 204 (such as an ultrasound device 300, an RF device 330, or a multi-functional device 360). Figure 3 The product code of the surgical instrument connected to the energy module 204, the instrument settings of the surgical instrument (such as power, displacement, voltage or impedance or combinations thereof), the activation time of the surgical instrument as measured by the energy module 204 or the timer 626, the surgical procedure, the smoke density and / or thickness of the smoke 812 at the surgical site as measured by the drainage module 208 or the visualization module 212 (e.g., the clarity of the patient's body cavity as detected by the camera of the visualization module 212) or the type of tissue at the surgical site as visualized by the camera of the visualization module 212 or detected by the head module 202 (e.g., as discussed elsewhere herein), or combinations thereof.

[0120] Based on the collected data, controller 620 can be operated to automatically adjust the suction motor 820 and / or the blow-in motor 718. As an example, controller 620 can determine that a clinician is using a high displacement setting of the ultrasonic surgical instrument 300 to cut liver tissue. Therefore, when additional smoke is expected to be generated, controller 620 can increase the speed of the suction motor 820. As another example, controller 620 can detect via the camera of visualization module 210 that abdominal clarity has decreased below a clarity threshold. Therefore, controller 620 can automatically power the suction motor 820 and de-energize it after the clarity has reached or exceeded the clarity threshold. Thus, controller 620 can use each of the foregoing factors to select the appropriate operating time, pressure, and flow rate of the suction motor 820 and / or the blow-in motor 718 to maximize the performance of the modular surgical system 600.

[0121] Figure 15 It is a control based on at least one aspect of this disclosure Figure 6 A schematic flowchart of an example method 1500 for a modular surgical system 600. Method 1500 can be embodied in a controller 620 ( Figure 6 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input provided to controller 620 (such as on touchscreen 630) Figure 6 (to be executed at) (place).

[0122] refer to Figure 6 and Figure 15 Method 1500 may include receiving input indicating parameters, as at step 1502. For example, controller 620 may receive parameters from a data source, such as any of the modules, sensors, instruments, or devices described elsewhere herein. Parameters may be smoke density, smoke thickness, smoke volume, clarity, or any other suitable parameters described elsewhere herein.

[0123] Method 1500 may further include comparing the parameter with a threshold, as at step 1504. For example, controller 620 may retrieve the corresponding threshold from memory 624 and compare the value of the received parameter with the threshold. If the value of the parameter is lower than the threshold, controller 620 may loop back to step 1502 and repeat the aforementioned steps of method 1500 until the value of the parameter exceeds the corresponding threshold.

[0124] If the parameter value is equal to or higher than the threshold, the controller 620 can proceed to adjust the blow-in module and / or the exhaust module, as at step 1506. For example, when the parameter value reaches or exceeds the threshold, the controller 620 may be able to operate to power the blow-in module 210 (in the event of a power failure), power the exhaust module 208 (in the event of a power failure), and adjust the parameters of the blow-in module 210 (when it is already powered), such as the blow-in motor 718 ( Figure 7 The speed of the pumping module 208, or the parameters of the pumping motor 820 (when powered), can be adjusted. Figure 8 The speed of ), or combinations thereof.

[0125] Method 1500 may further include comparing the parameter with a threshold, as at step 1508. For example, after a threshold amount of time has elapsed since the adjustment was made at step 1506, the controller 620 may again compare the value of the parameter with the corresponding threshold. If the value of the parameter is now below the threshold, the controller 620 may loop back to step 1502 and repeat the aforementioned steps of method 1500.

[0126] However, if the parameter value remains at or above the threshold, the controller 620 may be able to operate to generate an alarm, as at step 1510, and / or de-energize the surgical instruments, as at step 1512. For example, based on the fact that the parameter value still exceeds the threshold despite adjustment at step 1508, the controller 620 may proceed to de-energize the surgical instruments (such as one of surgical instruments 300, 330, 360) to prevent the generation of additional smoke at the surgical site until a corrective action is taken. The corrective action may include allowing the aspiration module 208 to aspirate smoke mist 812 from the patient's body cavity without activating the surgical instruments. Figure 8The controller 620 can also generate alarms, such as visual alarms via LCD 640, audible alarms via speaker 650, and / or tactile alarms via a motor located in one of the surgical instruments.

[0127] use AI Learn about optimal smoke exhaust system settings and performance Much of smoke extraction is unknown, particularly regarding acceptable flow rates, visibility based on the settings used, and the time required to remove smoke. One way to achieve smarter smoke removal is through artificial intelligence (AI).

[0128] Refer again Figure 6 The controller 620 of head module 202 may include an AI platform that collects data from multiple data sources, such as any of the modules, sensors, instruments, or devices described elsewhere herein. The AI ​​platform can utilize the collected data to develop optimal settings for the pump module 208, such as the pump motor 820 ( Figure 8 The pre-selection speed. The types of data collected by the AI ​​platform can include the surgical instruments used (such as one of the surgical instruments 300, 330, or 360). Figure 3 The type and energy mode of the procedure, the type of surgery (e.g., open, laparoscopic, gastrectomy, etc.), the type of tissue being operated on, the amount or visibility of the power supplied, or a combination thereof.

[0129] Using this information, the AI ​​platform of controller 620 can become more efficient and intelligent over time by customizing settings for the type of surgery and device. This will allow surgical staff to select the optimal configuration for best visibility and removal of harmful plumes for a specific surgical type on touchscreen 630 during the preoperative period. This configuration can include optimal flow rate, flow time, and activation period. These configurations can make the modular surgical system 600 more efficient and eliminate guesswork for OR staff. This also helps improve setup time and allows OR staff to avoid monitoring the aspirator module 208 during use.
