[0004] This application relates to the field of automated fluid management systems. Background Technology

[0005] For several reasons, flexible ureteroscopy (fURS) procedures require fluid circulation. Today, surgeons deliver fluid in various ways, such as by suspending a fluid bag and using gravity to deliver fluid, filling a syringe and manually injecting fluid, or using a peristaltic pump to deliver fluid from a reservoir at a constant pressure or flow rate. A drawback of these and other delivery methods is that the user does not fully understand what the pressure collection system or anatomy (ureter, bladder, kidney) is undergoing, which increases the risk of patient injury. Conservative surgeons typically circulate fluid at low pressure. However, reducing the flow rate to maintain low pressure can directly affect visualization of the surgical area, as blood, clots, and particulate matter may not be adequately cleared at low pressure. In contrast, high perfusion flow rates can achieve the desired clear visibility but can lead to excessively high intraluminal pressure. High intraluminal pressure makes it easier for bacteria and endotoxins to be absorbed into the bloodstream, which can lead to postoperative fever. Other complications that may occur due to high intraluminal pressure include lymph node and venous reflux, resulting in fluid leakage, postoperative pain, urosepsis, and kidney damage.

[0063] The invention will be understood with reference to the following description and accompanying drawings, wherein like elements are designated by like reference numerals. The present invention relates to systems, methods, apparatuses, and kits for delivering fluid in a fURS procedure via controlled flow and sensor feedback. An exemplary embodiment describes a modular system comprising: a user-controlled or automated pump; and a ureteroscope, such as, for example, a LithoVue with a sensor at the distal end. TM The device includes a mirror assembly; a fluid management system; and, in some embodiments, a drain collection system. If desired by the user, the pump system may include a heating source to heat the fluid to body temperature. Other exemplary embodiments describe a fluid management system kit that may include a flushing tube, a tool with a pressure or temperature sensor, any combination of any two or more drain tanks, and printed material having one or more of the following: stored information and instructions on how to set the flushing tube. It should be noted that the terms "proximal" and "distal" as used herein are intended to refer to the direction toward (proximal) and away from (distal) the device.

[0064] Figures 1-2 An exemplary modular fluid management system 10 is illustrated. The fluid management system 10 can be coupled to a surgical device that allows fluid flow through it and includes pressure sensors, such as the LithoVue. TMMirror device 20. In an exemplary embodiment, device 20 further includes: a temperature sensor for providing temperature feedback to system 10; and / or a camera for providing visual feedback to fluid management system 10. Fluid management system 10 also includes fluid hanger module 100. Exemplary fluid hanger module 100 may include one or more fluid container supports, such as fluid bag hangers 102, each of which supports one or more fluid bags 104. In one embodiment, the placement of fluid bags 104 can be detected using a remote sensor. Fluid bag hangers 102 can receive fluid bags 104 of various sizes, such as, for example, bags from 1 liter (L) to 5L. It should be understood that any number of fluid containers can be used. Furthermore, depending on the procedure, fluid containers of any size can be used. Exemplary fluid management unit 100 may be mounted to a rolling bracket, which may include a rod 106 and / or a base 108. Base 108 may include multiple wheels to facilitate easy movement of fluid management unit 100 during use. However, it will be understood that, depending on clinical preference, the fluid bags 104 may also be suspended from or between the ceiling. The fluid bag hanger 102 extends from the rod 106 and may include one or more hooks 110 on which one or more fluid bags 104 may be suspended. The fluid used in the fluid management system 100 may be 0.9% saline. However, it should be understood that, depending on the procedure, various other fluids of different viscosities may be used.

[0065] The fluid management system 10 may also include one or more user interface components, such as a touchscreen interface 112. The touchscreen interface 112 includes a display screen 113 and may include switches or knobs in addition to touch capability. The touchscreen interface 112 allows the user to input / adjust various functions of the system 10, such as flow rate, pressure, or temperature. The user can also configure parameters and alarms (such as a maximum pressure alarm), information to be displayed, and program modes. The touchscreen interface 112 allows the user to add, modify, or terminate the use of various modular systems within the fluid management system 10. The touchscreen interface 112 can also be used to switch between automatic and manual modes of various programs in the system 10.

[0066] Figures 3-6 An exemplary touchscreen interface 112 is shown. Parts of the touchscreen interface 112 may be configured to resemble buttons and / or provide functionality similar to physical buttons, as those skilled in the art will understand. The display screen 113 may be configured to display icons 114 associated with the modular systems and devices included in the fluid management system 10. For example, in Figure 3 In this context, the display screen 113 provides the user with real-time video feedback 116 from the endoscope or medical device 20 on the target tissue / blood vessel / cavity. The display screen 113 may also include, for example... Figure 5The flow rate display 118 shown is used. The flow rate display 118 can be determined based on a desired flow rate threshold set by the user before the program runs, or based on known common values, etc. In some embodiments, operating parameters can be adjusted by touching a corresponding portion of the touchscreen interface 112. The exemplary flow rate display 118 then provides a flow rate scale 120 with, for example, different low, medium, and high ranges based on the user-input operating parameters and the actual flow rate 122. In real time, the flow rate display 118 adjusts the actual flow rate 122 and the rate marker on the flow rate scale 120. If the flow rate enters the high range, in this embodiment, a visual alarm 125 and / or an audible alarm, such as... Figure 5 As shown. Figure 4 As shown, a similar pressure display 119 can be provided on display screen 113. Again, the pressure scale 123 can be determined based on parameters previously input by the user or through known common values. Display screen 113 can also display the actual pressure 121 in real time. In other embodiments, display screen 113 may also show system power 127, the amount of fluid remaining in fluid bag 131, and any other information that the user may find useful during the surgical procedure, such as... Figure 5 It is visible in the text.

[0067] In one exemplary embodiment, the fluid management system 100 also includes additional user interface components, such as a foot pedal 117, a heater interface 168, a fluid control interface 127, or other devices, for manually controlling various modular systems. For example, the foot pedal 117 can be used to manually control the flow rate.

[0068] The touchscreen interface 112 is operatively connected to a main processing unit 124 (e.g., a computer) or an integral part thereof. The main processing unit 124 can be operatively connected to one or more system components, such as pump assemblies, heating assemblies, and fluid deficiency management systems. The main processing unit 124 is capable of performing various functions, such as calculation, control, display, etc. The main processing unit 124 is also capable of tracking and storing data related to the operation of the system 10 and each of its components. In an exemplary embodiment, the main processing unit 124 includes network communication capabilities, such as WiFi, through which the device can connect to, for example, a social local area network. The main processing unit 124 can also receive sensor signals from the system 10. In one embodiment, the main processing unit 124 can communicate with a database for the maintenance and best practice recommendations of patient records that can be displayed to the user on the display screen 113.

[0069] The fluid management system 10 can be selected by the user between different modes based on procedures, patient characteristics, etc. For example, different modes may include: fURS mode, BPH mode, hysteroscopy mode, cystoscopy mode, etc. Once the user has selected a mode, mode parameters, such as flow rate, pressure, fluid deficit, and temperature, are provided to the user via a display screen. Exemplary parameters for a specific mode can be predetermined and loaded onto the main processing unit 124 using, for example, software. Thus, when the user selects a program from the initial display on the touchscreen interface display 113, these known parameters are loaded from the processor into the various components of the fluid management system, namely the pump, heating assembly, and fluid deficit management system. The fluid management system 10 can also be selected by the user between automatic and manual modes. For example, for some procedures, the user may wish to manually adjust the flow rate, pressure, or other parameters. Once the user selects a manual mode, for example, on the touchscreen interface 112, the user can adjust the flow rate or pressure via other manual interfaces, such as the foot pedal 117 or the fluid control interface 127.

[0070] The main processing unit 124 may be configured to include vision software / image recognition software that can detect visual noise based on changes in brightness (i.e., light monitoring), contrast, or color animation. If it is determined that the image provided to the main processing unit 124 is not clear or discernible enough, the fluid management system 10 increases the flow rate of fluid to flush away the debris 129, thereby making the image clear / discernible. The flow rate is increased temporarily (i.e., within a predetermined time period) or until the field of view is deemed sufficiently clear. This temporary increase ensures that the time of the flow rate increase is limited to ensure that the pressure does not exceed safe limits. For example, the system 10 may identify situations such as... Figure 7 The system detects a reddish hue (signs of blood) and signals a set of peristaltic pumps 126 to increase the flow rate until the blood is cleared from the field of vision. Alternatively, the processor can provide a visual alert on display 113 or an audible alert to a doctor or nurse indicating that a cloudy view has been detected, and the user can then manually adjust the flushing flow rate. In another example, in the presence of a large amount of debris, the light reflected from the debris will generally brighten the image. In this case, the main processing unit 124 detects this excessive brightness and signals the pumps 126 to increase the flow rate to remove the debris. Once the reflected light has decreased as the debris has been flushed cleared from the field of vision, the pumps 126 are controlled by the main processing unit 124 to reduce the flow rate. Preferably, the doctor can create a baseline level for visibility at which he or she prefers to initiate a visual field clearing fluid flow, and input these parameters into the system 10 via the touchscreen interface 112 before the procedure. Once the baseline has been created, the system 10 monitors visual feedback for changes in the image and adjusts the flow rate as needed.

[0071] To regulate the flow rate of fluid through system 10, fluid management unit 100 may include one or more booster devices, such as pump 126. An exemplary pump 126 may be a peristaltic pump. Pump 126 may be electrically driven and may receive power from a corded source, such as a wall socket, or an external or internal electrical storage device, such as a disposable or rechargeable battery. Peristaltic pump 126 may operate at any desired speed sufficient to deliver fluid at a target pressure, such as, for example, 5 mmHg to 50 mmHg. As previously noted, pump 126 may be automatically adjusted based on, for example, pressure and temperature readings within the patient's body and visual feedback from mirror 20. Pump 126 may also be transmitted via, for example, a foot pedal 117, a touchscreen interface 112, or a separate fluid controller 127 (e.g., Figure 4 (As shown in the diagram) Manual adjustment. The fluid controller 127 may be a separate user interface, which includes buttons allowing the user to increase or decrease the flow rate of each individual pump 126. It should be understood that any number of pumps can be used. In one embodiment, the system 10 may include multiple pumps with different flow capacities. Flow meters are located before or after the pumps.

[0072] In this embodiment, the fluid flow rate at any given time is displayed on display screen 113 to allow for visibility of any changes in the operating room (OR). If OR personnel notice a flow rate variation that is too high or too low, the user can manually adjust the flow rate back to a preferred level. This may happen, for example, when a physician inserts and removes instruments into the working channel of endoscope 20. As discussed earlier, system 10 can also monitor and automatically adjust the flow rate based on previously set parameters. This feature can also be beneficial when flow is provided manually, such as when an assistant injects flushing via syringe.

[0073] As noted above, in one embodiment, system 10 may include vision software or image recognition and analysis software. In this embodiment, system 10 may detect whether a tool has been inserted and which tool is being used via a camera 128 positioned on a mirror 20 located within the body. For example, the tool may have an identifiable marking that the vision software can see to inform the system what type of tool is being used. The fluid management system 10 may then automatically adjust the flow rate based on the tool identified by the vision software. When the tool is retracted from the working channel, the fluid management system 10 correspondingly reduces the pump rate.

[0074] In another embodiment, system 10 automatically adjusts the flow rate based on pressure and / or temperature detected within the patient. Pressure and / or temperature can be measured in parallel using a tool (such as endoscope 20) used in conjunction with system 10. System 10 may include pressure monitoring software that allows pump 126 to be configured by the user to automatically start, stop, and / or adjust its speed by system 10 to maintain the fluid pressure delivered to the surgical site at a target pressure and / or within a predetermined pressure range. For example, an endoscope pressure sensor can detect intrarenal pressure and automatically change the flow rate within system 10 based on the monitored intrarenal pressure. If the intrarenal pressure is too high, system 10 will reduce the flow rate, and vice versa. In an exemplary temperature control mode, system 10 may include temperature monitoring software that allows the heater to be controlled (e.g., started, stopped, and adjusted) to maintain the fluid temperature delivered to the surgical site at approximately a target temperature and / or within a predetermined temperature and pressure range, as will be described in more detail below. For example, temperature can be monitored in vivo or in vitro, and fluid flow can be modified based on the provided temperature feedback. In one exemplary embodiment, system 10 can compare the temperature and pressure sensed within the kidney with known values ​​and provide a warning when the parameters are outside a predetermined safe zone. The warning can be a visual or audible alarm.

[0075] In one embodiment, system 10 can monitor the movement of a target structure (e.g., a kidney stone). The system can calculate the movement rate based on the stone's initial position and its new position. If the movement exceeds a predetermined threshold, the system can alert the user to manually adjust the system's flow rate. As described above, the flow rate can be manually adjusted via a foot pedal 117, a touchscreen interface 112, or a pump interface. In one embodiment, if system 10 is in automatic mode, it will automatically adjust the flushing flow rate as needed. This capability can be very beneficial during procedures such as lithotripsy to control the retreat of the stone.

[0076] like Figures 9-10 As shown, the endoscope device 20 can be, for example, a ureteroscope, such as a LithoVue. TM Mirror. LithoVue TM The endoscope is lighter than many existing models, thus reducing the workload of clinicians. The endoscope 20 delivers fluid from the fluid management system 10 to the target tissue via the endoscope shaft 169. As described above, the endoscope 20 is connected to the fluid management system 10 via a supply line (i.e., a tube). The supply line from the fluid management system 10 to the endoscope 20 is preferably formed of a material that helps to suppress peristaltic movement generated by the pump 126. Figure 9As shown, the mirror 20 may include a pressure transducer 170 at the distal end of the mirror axis 169 to measure, for example, pressure within the kidney. The mirror 20 may also include other sensors, such as a temperature sensor. In an exemplary embodiment, the distal end 172 of the mirror 20 may also include at least one camera 128 to provide visual feeds to the user on the display screen 113. In another embodiment, the mirror 20 may include two cameras 128 with different communication requirements, such that different information can be conveyed to the user through each camera 128. In this embodiment, the user can freely switch between cameras 128 via a touchscreen interface 112. The mirror 20 includes a handle 174. The handle 174 may have a fluid flow on / off switch 176 that allows the user to control when fluid flows through the mirror 20 and into the patient's body. The handle 174 may further include other buttons 177 that perform various other functions. For example, in one embodiment, the mirror handle 174 may include a button for controlling the temperature of the mirror or the fluid. In another embodiment, the mirror handle 174 may include a laser that allows the user to emit laser energy. In one exemplary embodiment, the laser may be a Lumenis or StarMed Tech laser. A laser fiber may be connected to the laser system and inserted through the working channel of the ureteroscope. The user can fire the laser, causing energy to exit from the tip of the laser fiber, which strikes fragments / stones to break them. In an exemplary embodiment including a laser button on the endoscope, a communication line (i.e., hardwired or wireless) is maintained between the laser system and the endoscope. It should be understood that while the exemplary embodiment describes a ureteroscope, the features detailed above can also be directly integrated into a cystoscope, hysteroscope, or virtually any imaging-capable device. Endoscope 20 may also include a drainage port 178, which can be connected to a drainage system described in more detail below.

[0077] The fluid management system 10 may include a fluid deficiency monitoring system 130. In one exemplary embodiment, the fluid deficiency monitoring system 130 monitors the amount of fluid (i.e., saline solution) in the fluid bag 104 by weight. In this embodiment, a weight sensor 132, such as a scale, is suspended from a hook 110. The weight sensor 132 may also include a hook 134, on which one or more fluid bags 104 are suspended. The weight sensor 132 determines the weight of the fluid bags 104 attached to the suspension module 100 to compare the initial amount of fluid in the fluid bags 104 with the current amount of fluid remaining in the fluid bags 104. The scale reading is displayed to the user on a display screen 113, such as... Figures 4-5As shown in the diagram. As the procedure progresses, the scale reading is updated in real time to alert the doctor how much fluid remains in the fluid bag 104, and this amount can then be used to determine the amount of fluid already infused into the patient. In one exemplary embodiment, the system 10 provides the amount of time remaining before a new bag is needed, based on the weight of the bag 104 and the rate at which the bag 104 is emptied (i.e., the flow rate). In another embodiment, the remaining fluid volume can be represented as a fluid shortage bar 131, as shown in the diagram. Figure 6 As can be seen in the image, when, for example, 10% of the saline solution remains in bag 104, an alarm with an audible signal can be displayed on display 113. In one exemplary embodiment, weight sensor 132 can be connected to display 113 via a WiFi signal. In another exemplary embodiment, weight sensor 132 can be connected to display 113 via a hardwired connection.

[0078] In another exemplary embodiment, the fluid depletion monitoring system 130 may include a pressure sensor inline connected between the fluid bag 104 and the device 20. In this embodiment, the pressure is determined based on the height of the fluid bag 104. As the bag empties, the amount of pressure released decreases. When the pressure drops below a user-defined threshold, an alarm is displayed on the display screen 113 and an audible signal is emitted. In another exemplary embodiment, the fluid depletion monitoring system 130 may be set to a specific flow rate based on the amount of time elapsed. A physician may input the fluid volume from the bag into the system 10, and the system 10 then calculates the amount of fluid used and how much remains based on the known flow rate and the amount of time already used by the system 10.

[0079] The fluid management system 10 can utilize small-diameter pump tubing 136 to connect various components. An exemplary tubing 136 used for flushing procedures may have a diameter less than or equal to 1 / 16 inch. However, it should be understood that tubing size can vary depending on the application. Tubing can be disposable and supplied as sterile, and is ready for immediate use. Different types of tubing can be used for various functions within system 10. For example, one type of tubing can be used for fluid heating and fluid flow control to device 20, while another type can be used for intracavitary flushing.

[0080] In one exemplary embodiment, the fluid management system 10 may optionally include a heater assembly 138 for heating the fluid to be delivered to the patient, such as... Figures 11-12As shown in the diagram. The heater assembly 138 includes a heater 140, a heater housing 142, and a clamping mechanism 144 for the housing 142. An exemplary housing 142 may include a fluid outlet port 148 and a fluid inlet port 146 located on a lateral side of the housing 142. The fluid inlet port 146 and the fluid outlet port 148 each include an inlet connector 150 and an outlet connector 152 extending respectively from the lateral side of the housing 142. Connectors 150, 152 may be in the form of Luer locking fittings, barbed fittings, quick-connect fittings, etc. Connectors 150, 152 connect the heater assembly 138 to other components of the fluid management system 10. For example, the fluid inlet port 146 may be connected to the pump 126 via a fluid conduit 136, while the fluid outlet port 148 may be connected to the device 20. In an exemplary embodiment, the housing 142 includes an internal flow path along a channel 154 through which fluid can flow from the inlet connector 150 to the outlet connector 152, such as... Figure 12 As shown in the diagram. The housing 142 may include one or more fluid paths. If multiple fluid paths are present, one or more walls 156 may separate the respective fluid channels 154. An exemplary fluid channel 154 includes a horizontal section 158 and a vertical section 160 to form a swirling fluid path between a fluid inlet port 146 and a fluid outlet port 148. The fluid channel 154 is configured to provide a large amount of outward-facing surface area relative to the internal volume to facilitate effective heating of the fluid by the heater 140. In an exemplary embodiment, fluid enters the housing 142 via the inlet port 146 and enters the lower horizontal section 158a. The fluid flows through the vertical section 160a and reverses direction to flow through a first intermediate horizontal section 158b. The fluid follows the channel 154 in this manner until it flows through the outlet port 148. The sections 158, 160 of the channel 154 are separated by the horizontal walls 156. The housing 142 may be formed of, for example, polycarbonate or any heat-rated biocompatible plastic, and may be formed as a single piece or as multiple pieces permanently bonded together. The inlet connector 150 and the outlet connector 152 may be integrally formed with the housing 142, or may be separately disposed pieces, as those skilled in the art will understand.

[0081] Box 142 is connected to heater 140 via clamping mechanism 144. Figure 11In an exemplary embodiment, the clamping mechanism 144 is configured as two side plates 162, wherein a slot 164 extends between the side plates 162 for receiving the cassette 142. In an exemplary embodiment, the slot 164 may include a guide (not shown) to assist a user in inserting the cassette 142 into the slot 164. When inserted into the slot 164, the side plates 162 are clamped around the cassette 142 by two knobs 166. Rotation of the knobs 166 in a first direction moves the side plates 162 closer together to clamp the cassette 142 in place between the side plates 162, while rotation of the knobs 166 in a second direction moves the side plates 162 apart to allow the cassette 142 to slide out of the slot 164. The clamping mechanism 144 can be attached to the lever 106 by any device (e.g., an adjustable lever clamp) such that the clamping mechanism 144 and the heater assembly 138 can slide along the lever 106 to a desired position.

[0082] Box 142 is designed so that when box 142 is inserted into slot 164 of heater assembly 138 (e.g.) Figure 11 As shown in the diagram, channel segments 158, 160 are generally aligned with heater 140. Heater 140 may include one or more heat sources using electrical energy, such as, for example, parallel coils or pressure plate systems in a fluid supply line. Heating may be specifically designed and tailored to suit the flow rate required for a particular application of system 10. Heater 140 may be located in one or both of the side plates 162. In one exemplary embodiment, heater 140 surrounds the entire inner surface area of ​​plate 162. In another exemplary embodiment, heater 140 may be located only in the upper portion of one or both of the plates 162. It should be understood that heater 140 may be located anywhere on heater assembly 138 adjacent to the fluid flowing through it.

[0083] Heater assembly 138 may include heater user interface 168. Heater user interface 168 may simply be a display screen (not shown) that provides a digital display of the heater's internal temperature. In another embodiment, user interface 168 may also include temperature adjustment buttons to increase or decrease the temperature of heater 140. In this embodiment, the heater display screen (not shown) may indicate the heater's current temperature and the target temperature to be achieved. It should be noted that all information output from heater assembly 138 can be directly transmitted to display screen 113, making heater user interface 168 unnecessary.

[0084] In one exemplary embodiment, temperature sensors are mounted in the heater assembly 140 such that they detect the temperature of the fluid flowing through the cartridge 142. These sensors may be located at or near the fluid inlet port 146 and the fluid outlet port 148. In one exemplary embodiment, the temperature sensors may be mounted such that they detect the temperature of the fluid flowing through the cartridge 142 before the fluid enters the channel 154 and after the fluid leaves the fluid channel 154. In some embodiments, additional sensors may be located in the middle portion of the channel 154 such that they detect the progression of temperature rise in the fluid within the cartridge 142. The sensors may remotely transmit any information to the display screen 113, or they may transmit information to the heater user interface display screen. In another embodiment, the sensors are hardwired to the heater user interface 168, thereby enabling the heater user interface 168 to remotely transmit desired information to the system display screen 113.

[0085] The fluid management system 10 may include a waste management system 200. An exemplary waste management system may simply be a pipe leading from a fluid disposal port in mirror 20 to a drain bag or collection container 180. Waste collection may be via a tank on the platform or direct feed to an alternative system. Figure 13 In the embodiments shown, for example, one or more waste collection containers or canisters 202 (five in this embodiment) may be used in combination with a vacuum pump (not shown) to aspirate waste from the patient into the collection container 202. It will be understood that while the embodiments herein show five collection containers, any number of containers can be used. For example, Figure 34 Another exemplary embodiment using three collection containers is shown. A tube 236 linearly connects each of the collection containers 202 to the next, such that the collection containers 202 are filled one at a time. Specifically, as the first collection container 202 fills, waste begins to flow into the subsequent collection containers, and so on, until each collection container is full. However, one problem with this “daisy chain” system is that the vacuum (not shown) must be shut off to swap the full waste collection containers 202 out of the system. Furthermore, the system 200 is not easily pre-arranged vertically for placement or removal as a group when full, thus increasing potential vacuum downtime.

[0086] exist Figure 14The image shows a waste management system 300 according to an alternative embodiment that addresses the problems of a "daisy chain" system. In this embodiment, similar to waste management system 200, five collection containers 302A-302E and a vacuum pump 304 are used. However, it should be understood that any number of collection containers can be used depending on the procedure. This embodiment also includes an intermediate holding chamber 306, a two-position valve 308, and a conventional pinch valve 310. The intermediate holding chamber 306 is connected to the patient, a first collection container 302A, and the two-position pinch valve 310. The pinch valve 310 is positioned between the intermediate holding chamber 306 and the first collection container 302A and is operable to allow or prevent fluid waste from flowing into the first collection container 302A. The first collection container 302A is connected to a second container 302B, the second container 302B is connected to a third container 302C, and so on. Vacuum pump 304 is connected to intermediate holding chamber 306 and final collection container 302E via pipe 336 and two-position pinch valve 308, the two-position pinch valve 308 being as follows: Figure 14 The Y-pinch valve shown is a two-position pinch valve 308 that can be activated to allow flow to waste collection containers 302A-302E or intermediate holding chamber 306.

[0087] In use, waste fluid is pumped from the patient through intermediate holding chamber 306 and into waste collection container 302. When waste collection container 302 is full, pinch valve 310 and two-position valve 308 are activated, thereby blocking the connection between the patient and waste collection container 302, preventing waste from flowing into the collection container 302, thus allowing the user to replace the full container with an empty one or empty and replace the full one. When this occurs, intermediate holding chamber 306 collects waste from the patient until pinch valves 308, 310 are switched back to allow flow to the collection container 302 again. Therefore, system 300 allows the user to easily switch out of the used collection container 302 without having to shut off vacuum 304 or stop the flow of waste from the patient.

[0088] In one exemplary embodiment, according to Figure 15The diagram illustrates two manifold waste management systems 400. In this embodiment, the waste management system uses one manifold 406 for waste and another manifold 408 for a vacuum pump 404. Specifically, a line 410 extends from the patient and branches into separate tubes 410A-410E, each of which extends into a corresponding collection container 402. A second line 412 extends from the vacuum pump 404 and similarly branches into separate tubes 412A-412E, each of which extends into a corresponding collection container 402A-402E. Thus, the patient and the vacuum pump 404 are individually and separately connected to each of the collection containers 402A-402E. Multiple pinch valves 414A-414E are configured, each positioned on a corresponding one of pipelines 410A-410E and 412A-412E, to control vacuum suction and waste flow to the corresponding collection containers 402A-402E, such as... Figure 15 As shown in the diagram. In use, pinch valves 414A-414E can be activated to shut off vacuum pump 404 and prevent waste flow to unused collection containers, thereby controlling the flow so that only one collection container enters at a time. Furthermore, when collection container 402 is full, the corresponding pinch valve 414 can be activated to cut off the vacuum and waste flow to the full collection container, allowing the removal of the full collection container without interfering with the waste flow to other collection containers with free space.

[0089] Figure 16 An exemplary embodiment of a waste management system 402' with a single manifold is shown. In this embodiment, the waste management system uses a single manifold 406' that attaches both the patient and the vacuum pump to individual collection containers. Specifically, two lines 410' extending from the patient and vacuum pump 404' branch into separate pipes 410A-410E', each corresponding to one of the collection containers 402'. Similar to system 400, each collection container 402A-402E' has an associated pinch valve 414A-414E' that controls the flow to the corresponding collection container, such that, for example, flow can be allowed to reach only a single collection container at a time. Thus, the pinch valves can be operated to allow or prevent flow to the collection container in any desired combination, thereby allowing the removal of a full collection container without interfering with the waste flow to other collection containers with remaining space.

[0090] In another exemplary embodiment, according to Figure 17The waste management system 500 includes three vacuum pumps 504 and a two-position pinch valve 506. In this embodiment, each group 502, 502' (groups 502A and B in group 502 and groups 502A' and 502B' in group 502') with two collection containers has its own vacuum pump 504. The individual collection container 502'' includes a pump 504 for suspension. A tubing 510 extends from the patient and branches at the pinch valve 506 into separate tubing 510', 510'', each extending to a corresponding collection container in one of the collection container groups 502, 502'. In other words, the first collection containers 502B and 502B' in each set of collection containers 502 are connected to the patient via pipes 510' and 510'', respectively, while the second collection containers 502A and 502A' in each set of 502 are connected to the first collection containers 502A and 502A' via connecting pipes 511 and 511', respectively, and connected to the vacuum pump 514 via pipes 513 and 513', respectively. A two-position pinch valve 506 is positioned between the patient and the set of collection containers 502 and is operated to allow waste to flow into only one collection container at a time. This restriction on waste flow allows for the replacement or emptying of a full waste collection container as needed, while flow continues to another container. Figure 18 In another exemplary embodiment shown, the system can be used as a dual vacuum system without a drape vacuum.

[0091] In use, the components of the waste management system 200-500 can be arranged in various configurations according to the program to promote accessibility and functionality. In the first embodiment, such as Figure 19 As shown, the waste management system 200 can be mounted to the ceiling 192. It should be understood that any of the waste management systems 300, 400, 400', and 500 can be arranged using various configurations described herein. In this embodiment, waste collection containers 202 can be embedded in the front shelf 194 and arranged side-by-side for easy access and removal. The ceiling-mounted assembly 190 keeps the floor uncluttered in space-constrained applications. Figure 20 In another exemplary embodiment shown (which is further discussed below), the waste management system 200 may include a universal mounting bracket (not shown) for easy mounting to, for example, an IV pole. It should be understood that the universal mounting bracket can also be used to mount the waste management system 200 to a wall mount or even a desktop configuration. In another exemplary embodiment, a waste collection container in use may be attached to the IV pole 106 at waist height to allow for easier removal and disposal, as in… Figure 21 As can be seen in the image. In this embodiment, two or four waste collection containers 202 are held in each waist-level assembly 196, while ready (unused) waste collection containers 202 are located on the lower storage platform 198. In another exemplary embodiment, as shown... Figure 22 As shown, the waste management system may include separate modules for waste collection containers 202, such as floor bins 190'. In this embodiment, floor bins 190' may include separate compartments 192' for each of the waste collection containers 202. However, it should be understood that floor bins 190' may alternatively include a single compartment to hold all waste collection containers or a single disposable waste bag 196', as... Figure 23 As shown in the diagram. The floor box 190' may include wheels, allowing the collection container to be rolled as needed so as not to get in the way in the operating room.

[0092] To optimize the ergonomics, accessibility, and functionality of the fluid management system 10, the main subsystems, components, and modules of the fluid management system 10 can be arranged in various configurations according to the program. For example, the locations of pumps, saline bags, touchscreens, etc., can be arranged in any desired configuration to optimize accessibility for surgeons or those assisting in the surgery according to the program to be executed. In an exemplary embodiment, as shown... Figures 24-34 As shown, the fluid management system 10 is configured with modular options on a vertical IV rod 106 having a rolling base 108 and a vertical stacking of main components. This vertical stacking of components reduces the width of the fluid management system 10 (i.e., the fluid management system 10 is narrower), making the system 10 more compact and allowing it to be positioned in confined areas, such as within an operating room. In these embodiments, the rod 106 may include a bend 602 at its lower portion, allowing each of the components and modular options to be attached to the front of the rod 106 without interfering with the weight distribution of the system 10.

[0093] In this embodiment, the collection container 202 is positioned around the bottom of the rod 106 in a compact configuration. Figure 24 In the exemplary embodiment shown, the collection container is weighed by a suspended weight mechanism 604. The suspended weight mechanism 604 can be coupled to a rod 106 and includes multiple individual compartments 606 for loading the collection container 202. Figure 24 and Figure 26 In one embodiment, the suspended weight mechanism 604 includes five compartments 606. However, it should be understood that any number of collection container compartments 606 can be used depending on the procedure and fluid waste level. Each compartment 606 includes an opening (not shown) in which the collection container 202 is placed. The suspended weight mechanism 604 may include a weight sensor (not shown). In another embodiment, each compartment 604 may include a weight sensor (not shown) for detecting changes in the weight of the container 202 loaded in the respective compartment. In other embodiments, such as Figures 26-27As shown, the collection container 202 can be mounted onto various substrates 610. Each substrate 610 may include a weight sensor (not shown) that detects changes in the weight of the collection container 202 mounted on the respective substrate 610. In another exemplary embodiment, the collection container can be mounted onto... Figure 28 The rotary drum 612 is shown. The drum 612 can be rotated manually or automatically. Additional supports 614 can be added to stabilize the drum 612 and the collection container 202. In this embodiment, the collection container can be weighed as a set or individually. Alternatively, an optical level sensor (not shown) can be used to monitor changes in the fluid level within the collection container.

[0094] Depending on user preferences or available space constraints, the display unit 616 may or may not be integrated with vertically stacked components. For example, it might be preferable to position the display unit 616 on a table at a different angle than any angle that could be provided if the display were attached to the rod 106. Alternatively, in another example, integrating the display unit 616 with stacked components might increase the height of the vertical stack, making it unsuitable for use within a designated space in the operating room. In these cases, such as... Figure 24 and Figure 27 In the embodiment shown, the display unit 616 is not integrated with the IV bar and stacked components, but is a separate display unit so that it can be placed in the desired location. However, in other embodiments, the display unit 616 may be attached to the top of the bent IV bar 106, for example as... Figure 25 , Figure 28 Visible in the middle. This position of the display unit 616 at the top of the IV bar 106 allows for greater user visibility while preventing the display unit 161 from being obstructed by other components of the system 10. In some embodiments, multiple displays can be used to implement multiple imaging modalities. For example, in Figure 31 and Figure 34 In the illustrated embodiment, system 10 may include an operator display 618 and a surgical display 620. In this embodiment, displays 618, 620 may be positioned to enhance visibility within the operating room. Displays 618, 620 can be configured as follows: Figure 31 , Figure 34 The swing hinge 617 shown is connected to system 10 to allow users and / or support personnel to move the screen to a desired angle to improve visibility. In another embodiment ( Figure 32 As shown in the diagram, the operator display 618 can be connected to the system 10 via a rotating hinge 619. The rotating hinge 619 is a multi-directional hinge that provides greater mobility to the screen, allowing the user to position the screen 618 more easily.

[0095] The positioning of the fluid saline bag 104 can also vary depending on loading, height, visibility, and access preferences. In some cases, it may be preferable that the fluid bag 104 is easily visible to the user. For example, a physician may want to see the rate of saline administration or the saline level remaining in each fluid bag 104 to know when the fluid bag 104 should be replaced. In another example, the process may require access to the top or rear of the Y-pinch valve in the tubing. Figures 24-28 and Figure 34 In the embodiments shown, the fluid bag 104 can be mounted to the top of the IV bar. This high mounting allows the user or support personnel to easily see the fluid bag 104, while also allowing the tube 136 to hang down to facilitate fluid flow. In one embodiment, as Figure 28 As shown, an external display is mounted on top of the IV pole, and the fluid bag 104 can be positioned behind the display. This rear accessibility allows support personnel to access the fluid bag 104 from behind the system 10 without interfering with the user's access to the modular components of the system 10. In another exemplary embodiment, the fluid bag 104 can be mounted to the bottom of the modular components of the system 10. For example, as... Figure 35 As shown, the fluid bag 104 can be mounted to the bottom of the pump 126. This embodiment includes optimal loading accessibility for the user / doctor while also allowing good visibility of the fluid bag 104. Figure 36 In another exemplary embodiment shown, the fluid bags 104 may be corner-mounted. That is, each of the fluid bags 104 may be mounted at an angle behind the modular system. This configuration provides good loading height and rear accessibility for support personnel to set up or replace the bags. Figure 37 In another exemplary embodiment shown, the fluid bag 104 may also be corner-mounted. However, compared to... Figure 36 Unlike the fluid bag 104 shown which is mounted at an angle, the fluid bag 104 is coaxially mounted at the rear of the modular system. Figure 36 Similar to other embodiments, this configuration provides support personnel with good loading height and rear accessibility for easy setup and saline bag replacement. In some exemplary embodiments, the saline bag hanger may be a retractable hanger. For example, the hanger arm may be able to rotate / pivot inward, thereby pulling the bag closer to the body. In another example, the arm itself may be telescopic. This retractable hanger allows for easy loading (especially if multiple bags are suspended) and minimizes space requirements.

[0096] In the vertically stacked embodiment, the pumps 126 can be grouped by vertical or horizontal groups or combinations thereof, such as Figures 24-34As can be seen in the diagram. That is, in the system 10, which includes multiple input and / or output pumps in the fluid management unit 100, pumps 126 can be grouped into different groups to facilitate better fluid flow and provide different fluid flow paths and efficiencies. For example, high / low flow output pumps 622 can be grouped vertically, or as... Figures 24-26 and Figure 28 As shown, the high / low flow output pumps 622 can be grouped horizontally. Similarly, the high / low output pumps 622 can be grouped vertically with the input pumps 624, or they can be horizontally aligned with the input pumps 624, as shown. Figure 27 As shown in the illustration. Furthermore, in some embodiments ( Figures 27-28 As shown in the diagram, the input pump 624 / output pump 622 can have a symmetrical arrangement relative to the entire system 10, wherein the input pump 624 is spaced apart from the output pump. Alternatively, the input pump 624 and the output pump 622 can be positioned adjacent to each other, such as... Figure 24 and Figure 26 As shown. In Figure 24 In an exemplary embodiment, the input pump 624 may be disposed in a different plane from the remaining output components (including the output pump 622). For example, the high / low output pump may be positioned at the front or first side of the system, while the input pump is positioned on the opposite side of the system. In an exemplary embodiment, the high / low output pump is retractable or covered for appropriate configuration. In each of the various configurations of the pumps, connections between the other modular components of the system 10 and the pumps are grouped with those between the input and output pump groups.

[0097] In some embodiments of the vertically stacked fluid management system 10, various additional features can be integrated. For example, in one embodiment ( Figures 29-30 In the embodiment shown, system 10 may include a filter nest for a flushing tube extending from the patient. The filter nest is used to hold a cylindrical filter that filters fluid returning from the patient so that it can be reused and pumped back into the patient. In other exemplary embodiments ( Figures 30-31 As shown in the diagram, system 10 may include a pinch valve to allow a user to stop the brine flow from fluid bag 104. In these embodiments, fluid bag 104 is positioned directly above the rest of system 10 to create a direct flow path from fluid bag to, for example, pump system 126. Figure 30 In one embodiment, the fluid bag hanger 102 can be angled forward from the rod 106 so that the fluid bag 104 is suspended in front of the unit, thereby allowing for easier fluid flow and greater visibility and accessibility for the user.

[0098] exist Figures 39-42In other exemplary embodiments shown, the fluid management system 10 may be positioned on a modular trolley 630 including a rolling base 608. The modular trolley 630 includes a rod 632 attached to the side of the modular trolley 630 and a flat, clean top surface 634 for arranging the various modular units. In one embodiment, such as Figure 39 As shown, the modular units can be stacked vertically. Specifically, the collection container 202 can be positioned below the flat surface 634 at the bottom of the modular cart 630. The collection container 202 can snap into a covered container compartment 636, which has an exposed hookup (not shown) for connecting the collection container to the patient and the rest of the fluid management system 10. A folded touchscreen 638, along with input pumps 624 and output pumps 622, can be positioned on the clean top surface 634, with the input pumps 624 and output pumps 622 spaced apart by the touchscreen 638. This layout is optimal for a compact modular cart and fluid management system 10. In this embodiment, the display unit 616 can be integrated with the modular cart 630 and coupled to the top of the pole 632, with the fluid bag 104 suspended from the bottom of the display unit 616 for easy access by the user or support personnel. Suspending the fluid bag 104 to the display unit 616 positions the bag 104 at a preferred loading height. For example, a saline bag can be positioned approximately 48 inches above the ground.

[0099] exist Figure 40 In another exemplary embodiment of the modular trolley-based system shown, the individual modular functional units can be horizontally stacked on a clean top surface 634. In this embodiment, a rod 632 can also be attached to the side of the modular trolley 630, wherein the fluid bag 104 is suspended from the top of the rod 632. A second side rod 640 is positioned on the opposite side of the trolley 634 for the display unit 616. The fluid bag 104 and the display unit 616 are positioned on opposite sides of the modular trolley 630 to balance each other, thereby providing better stability for the modular trolley 630. The input pump 624 and the output pump 622 can be arranged in a vertical group on the flat top surface 634, having a mechanical cover (not shown) or a retractable mechanism (not shown) for proper setup. Connectors (not shown) are grouped together with the input pump 624 and the output pump 622 group. A touch screen 638 can also be placed on the flat top surface 634. In this embodiment, the collection container 202 can be grouped in covered compartments 642 disposed on the flat top surface 634, such as Figure 40 As shown in the diagram, this elevated positioning of the collection container 202 on the flat top surface 634 allows for easier observation and replacement of the collection container 202 within the compartment 642.

[0100] In some situations, a more compact, modular trolley setup can be beneficial. For example, when available space in the operating room is very limited, a compact trolley may be necessary. Figure 41 In an exemplary embodiment, a minimalist modular cart arrangement can be seen, comprising a flat top surface 634 and a cart handle 632. In this embodiment, the flat top surface 634 may be positioned approximately 16 inches above the ground, providing just enough space beneath it for the collection container 202. The collection container 202 may be grouped in a front compartment 636, which has exposed connectors (not shown) for connecting the collection container 202 to the rest of the fluid management system 10. In this embodiment, the handle 632 is centrally located at the rear of the cart 630, wherein the fluid bag 104 is suspended from the fluid bag hanger 102 at the top portion for balancing and increasing the stability of the cart 630. All functional modular components (i.e., pumps, touchscreen, and connections) are positioned in a compact arrangement on the flat top surface 634. Specifically, the input pump 624 and output pump 622 are positioned horizontally, and the touchscreen 638 is a folded touchscreen to facilitate a small cart layout. To make the cart layout as compact as possible, this embodiment uses a separate external display unit 616, which can be placed in other parts of the room.

[0101] According to Figure 42 In another exemplary embodiment, the modular cart setup may include multiple stacked modules 644 that can be added or removed depending on the application. In this embodiment, the modular cart 630 includes a rod 632 for suspending the fluid bag 104 and a collection container compartment 636 located at the bottom of the cart 630. Each of the modular devices or systems may be positioned on a separate flat top surface 634, similar to a shelf, configured to connect to the rod 632. For example, a touchscreen 638 may be positioned on a removable flat top surface 634, an input pump 624 and an output pump 622 may be positioned on a second flat top surface 634, and a heater may be positioned on a third flat top surface 634. This removability of the flat top surfaces 634 increases the flexibility of the system 10, allowing components of the system 10 to be replaced depending on the patient or procedure. Furthermore, because fluid can be managed on the cart 630 separately from the modular components of the system, accessibility for support personnel is increased. The flat top surfaces may be connected to the rod via any suitable coupling mechanism. For example, the flat top surface can be mounted to the rod using screws or mounting tools.

[0102] The fluid management system 10 can be an open-loop or closed-loop system. As previously mentioned, the fluid management system 10 is a modular system, allowing the addition, replacement, or discontinuation of various modular components within the system 10. For example, the system 10 can be configured to include a heater assembly 138 for one application, and subsequently, the heater assembly 138 can be removed for different applications. The touchscreen interface 112 allows the addition and removal of various modular items, enabling the display screen 113 to show the user feedback and alerts associated with each modular item.

[0103] Power can be supplied to the fluid management system 10 by any known method, such as via a detachable cord. In one embodiment, some components can receive power from more than one power source. For example, one or more power supply units can provide appropriate voltage and current to various electrical loads. In the event of a power failure or unexpected disconnection, the main processing unit 124 can be protected by battery backup.

[0104] In an exemplary method of operating the fluid management system 10, a user may suspend one or more fluid bags 104 on one or more weight sensor hooks 134 extending from the weight sensor 132. The fluid bags 104 are connected to a peristaltic pump 126 via tubing 136. The pump 126 may be connected to a fluid inlet port 146 of the heater assembly 138 via another tubing 136. Another tubing 136 may connect the fluid outlet port 148 of the heater assembly 138 to the endoscope device 20. The operator may then use the touchscreen interface 112 to configure the fluid management system 10, which may include selecting surgical rules (modes), procedure type, the modular system being used, and setting fluid pressure, temperature, and flow setpoints, and / or other parameters (e.g., alarm setpoints, display content, and / or arrangement). When the endoscope 20 is inserted into a target passage (i.e., the bladder, ureter) within the patient's body, the user may initiate fluid circulation using a fluid flow on / off button 176 on the endoscope 20 or a touch button on the touchscreen interface 112. Sensors positioned on endoscope 20 provide feedback on the condition of the target anatomical structure in which the endoscope is positioned, and this feedback is then displayed on display screen 113. If the user has selected to place system 10 in automatic mode, changes in pressure, temperature, or visual feedback detected by the sensors can automatically trigger changes in the pump / flow rate if these changes exceed or fall below a specific set point. For example, such changes may occur to improve visualization, flush blood, urine, blood clots, or debris, or to compensate for reduced flow space within the working channel if an instrument has been inserted through the endoscope. Simultaneously, the change can be alerted to the user and / or the entire surgical team via audible or visual alarms. Once the sensors detect that the conditions have been normalized (i.e., an obstruction or instrument has been removed), system 10 will reduce the pump / flow rate. At any point in the procedure, the user can switch system 10 via touchscreen interface 112 or other physical switches, allowing its components (such as pump 126) to be manually adjusted. Manual adjustment can be made using foot pedal 117 or via touch buttons on display screen 113.

[0105] Simultaneously, various other modular devices and systems (such as heater assembly 138, pump 126, and fluid shortage monitoring system 130) can also provide the user with information about the operation of each system on display screen 113. For example, the heater assembly can display the fluid flowing through heater assembly 138 and the internal temperature of the heater. In another example, pump 126 can provide the pump rate to the display screen, and the fluid shortage system can provide the amount of time remaining before the existing fluid bag 104 should be replaced, as discussed above. The user can switch system 10 to manual mode at any time to manually control each component in the modular system.

[0106] Those skilled in the art will understand that the present apparatus and methods are not limited to the disclosed embodiments. For example, the disclosed fluid management system 10 can be used for a variety of other procedures, such as hysteroscopy, cystoscopy, TURP, etc. Therefore, system 10 is not limited to use with a ureteroscope, but can be used with other devices, such as a cystoscope, hysteroscope, or any other device with sensor and imaging capabilities.

[0107] Those skilled in the art will understand that changes can be made to the embodiments described above without departing from their inventive concept. It should also be understood that a structural feature and method associated with one of the embodiments can be incorporated into other embodiments. Therefore, it should be understood that the invention is not limited to the specific embodiments disclosed, and modifications are also included within the scope of the invention as defined by the appended claims.
