[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 604,630, filed November 30, 2023, the disclosure of which is incorporated herein by reference. Technical Field

[0002] This disclosure relates generally to medical fluid containers and methods, and more specifically to a container and tubing assembly for supplying fluids and / or gases to an endoscope. Background Technology

[0003] As is customary, endoscopic devices are widely used to perform diagnostic and / or therapeutic procedures. During endoscopic procedures, physicians can use a combination of air, irrigation, and lens cleaning as a means of flushing out debris, cleaning optics, and inflating the working lumen. For example, sterile water can be used during the procedure to irrigate the working lumen and / or remove organic matter (e.g., clots, feces, or other clumps) from the area of ​​interest. This can be achieved by spraying a low-velocity jet of water from an orifice at the tip of the endoscope. Furthermore, during endoscopic procedures, the video lens located at the distal end of the endoscope for navigation and visualization of target tissue can be easily contaminated with blood, mucus, and other debris. Physicians need to be able to clean the lens and working lumen throughout the procedure. To generate lens cleaning, a connector is attached to the endoscope's umbilical cord via a tubing kit. The tubing kit delivers air from the endoscope's umbilical cord to a water container or pressure vessel. A suction tube within this container or pressure vessel is in fluid contact with water and is connected to the connector. This allows pressure to be built into a water bottle or pressure vessel to deliver water along the tubing to the distal end of the endoscope, thereby cleaning the endoscope lens.

[0004] Endoscopic fluid delivery for both lens cleaning and irrigation processes can include a flexible tubing kit with a threaded cap that connects to a one-liter (L) semi-rigid bottle containing sterile water for irrigation. Commercially available tubing kits are available as either conventional dual-bottle tubing kits or hybrid tubing kits. Conventional tubing kits consist of two separate tubing kits connected to two separate bottles of sterile water. One kit connects to the one-liter sterile water bottle, while the second kit connects to a second bottle for irrigation. In contrast, hybrid tubing kits consist of a single tubing kit connected to a single one-liter water source, and this single system performs both irrigation and lens cleaning functions.

[0005] In some cases, it may be desirable to use readily available solution bags for sterile water or saline instead of bottles. Using solution bags can offer numerous advantages over current bottle-driven systems, including, but not limited to, allowing users to customize the volume of the fluid reservoir to suit their practical needs. For example, users can use readily available one-liter, two-liter, or three-liter solution bags, thereby reducing or avoiding the need to repeatedly change one-liter bottles throughout the surgical day.

[0006] Solution bags may require suspension. However, many endoscopy rooms have limited space and therefore no room for a separate intravenous (IV) pole to suspend the tubing kit solution bags. Therefore, a hanger is needed that would allow the solution bags to be suspended from an endoscopy cart, which typically houses capital equipment and one-liter bottles used in currently commercially available tubing kits. With these factors in mind, improvements to this disclosure may be useful. Summary of the Invention

Rather, it is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure. Detailed Implementation

[0057] This disclosure will now be described with reference to exemplary medical systems that can be used in endoscopic medical procedures. However, it should be noted that reference to this particular procedure is provided for convenience only and is not intended to limit the scope of this disclosure. Those skilled in the art will recognize that the core concepts of the disclosed apparatus and related methods of use can be applied to any suitable procedure (medical or other). This disclosure can be understood with reference to the following description and accompanying drawings, in which the same or similar reference numerals will be used to refer to the same or identical parts.

[0058] The term "distal" refers to the portion furthest from the user when the device is introduced into the patient's body. In contrast, the term "proximal" refers to the portion closest to the user when the device is placed into the patient's body. As used herein, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not necessarily include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. The term "exemplary" is used in the sense of "example" rather than "ideal." Further, as used herein, the terms "about," "approximately," and "substantially" indicate a range of values ​​within + / - 10% of the stated or implied values. Additionally, terms indicating the geometry of a component / surface refer to both exact and approximate shapes.

[0059] The embodiments of this disclosure are described with specific reference to bottles (e.g., containers, reservoirs, etc.) and tubing assemblies or kits. It should be understood that such embodiments can be used to supply fluids and / or gases to an endoscope for a variety of purposes, including, for example, facilitating patient inflatation, lens cleaning, and / or irrigating the working channel to aid in flushing / aspiration of debris during endoscopic procedures.

[0060] Although this disclosure includes a description of containers and tubing kits suitable for use with endoscope systems to supply fluids and / or gases to endoscopes, the devices, systems, and methods described herein can be implemented in other medical systems requiring fluid and / or gas delivery and for a variety of other purposes.

[0061] It should be noted that references to "embodiments," "some embodiments," or "other embodiments" in the specification indicate that the described embodiments may include specific features, structures, or characteristics, but each embodiment may not necessarily include that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Further, when a specific feature, structure, or characteristic is described in conjunction with an embodiment, whether explicitly described or not, implementing such a feature, structure, or characteristic in conjunction with other embodiments will be within the knowledge of those skilled in the art, unless expressly stated otherwise. That is, the individual elements described below, even if not explicitly shown in a specific combination, are considered to be combinable or arrangeable with each other to form other additional embodiments or to supplement and / or enrich the described embodiments, as will be understood by those skilled in the art.

[0062] As used in this specification and the appended claims, unless the context clearly indicates otherwise, the singular forms “a” and “the” include plural references. As used in this specification and the appended claims, the term “or” is generally used in its sense that it includes “and / or”, unless the context clearly indicates otherwise.

[0063] As is customary, endoscopic devices are widely used to perform diagnostic and / or therapeutic procedures. During endoscopic procedures, physicians can use a combination of air, irrigation, and lens cleaning as a means of flushing out debris, cleaning optics, and inflating the working lumen. For example, sterile water can be used to irrigate the working lumen during the procedure. Furthermore, during endoscopic procedures, the video lens located at the distal end of the endoscope, used for navigation and visualization of target tissue, can be easily contaminated with blood, mucus, and other debris. To generate lens cleaning, a connector is attached to the endoscope's umbilical cord via a tubing kit. The tubing kit delivers air from the endoscope's umbilical cord to a water container or pressure vessel. A suction tube within this container or pressure vessel is in fluid contact with water and is connected to the connector. This allows pressure to be built into the water bottle or pressure vessel to deliver water along the tubing to the distal end of the endoscope, thereby cleaning the endoscope lens. Tubing kits used to provide irrigation and / or lens cleaning fluids can typically be used for a 24-hour period across multiple endoscopic procedures. However, the same endoscope is not used for multiple patients and must be changed between procedures. At the end of the procedure, the connector is disconnected from the umbilical cord. Residual water in the tubing kit may spill onto the floor upon disconnection. Additionally, residual pressure in the connector or pressure vessel can create a siphon vacuum, causing all water in the container / pressure vessel to spill onto the floor via the tubing kit. Means to prevent water leakage and / or siphoning can prevent the user from cleaning water from the floor, prevent damage to capital equipment near or below the tubing connector, or eliminate the need for the user to prepare additional water containers or refill them for the next procedure. This document discloses devices and systems for preventing water from siphoning and / or leaking from water bottles and / or tubing kits after surgery.

[0064] refer to Figures 1 to 2 The illustration depicts an exemplary endoscope 100 and system 200, which may include an elongated shaft 100a inserted into a patient's body. A light source 205 supplies illumination light to a distal portion 100b of the endoscope 100, which may house an imager (e.g., a CCD or CMOS imager) (not shown). The light source 205 (e.g., a lamp) is housed in a video processing unit 210, which processes signals input from the imager and outputs the processed video signal to a video monitor (not shown) for viewing. The video processing unit 210 also serves as a component of an air / water supply loop by housing a pressure pump 215 (e.g., an air supply pump) within the unit.

[0065] The endoscope shaft 100a may include a distal end 100c disposed at a distal portion 100b of the shaft 100a and a flexible bend 105 proximal to the distal end 100c. The flexible bend 105 may include a hinge joint (not shown) to assist in swivel of the distal end 100c. On the end face 100d of the distal end 100c of the endoscope 100 is a gas / lens cleaning nozzle 220 for supplying gas to inflate the patient at the treatment area and for supplying water to clean the lens covering the imager. An irrigation opening 225 in the end face 100d supplies irrigation fluid to the patient's treatment area. The end face 100d of the distal end 100c may also include an illumination window (not shown) for transmitting illumination light to the treatment area, and an opening 230 leading to a working channel 235 extending along the shaft 100a for passing tools to the treatment area. The working channel 235 extends along the shaft 100a to the proximal channel opening 110, which is located distal to the operating handle 115 of the endoscope 100. The biopsy valve 120 can be used to seal the channel opening 110 to prevent unwanted fluid leakage.

[0066] The operating handle 115 may be provided with knobs 125 for providing remote four-way steering of the distal end via wires connected to articulated joints in the flexible portion 105 (e.g., one knob controls up-and-down steering, while another controls left-and-right steering). Multiple video switches 130 for remotely operating the video processing unit 210 may be arranged on the proximal side of the handle 115. Additionally, the handle 115 is provided with a dual valve well 135. One of the valve wells 135 may receive a gas / water valve 140 for operating the injection gas and lens water supply. Gas supply lines 240a and lens cleaning supply lines 245a extend distally from the gas / water valve 140 along the shaft 100a and converge at the distal end 100c proximal to the gas / cleaning nozzle 220. Figure 2 Another valve well 135 receives a suction valve 145 for operating suction operations. A suction supply line 250a extends distally from the suction valve 145 along shaft 100a to a junction in fluid communication with the working passage 235 of the endoscope 100.

[0067] The operating handle 115 is electrically and fluidly connected to the video processing unit 210 via a flexible umbilical cord 260 extending between the operating handle and the video processing unit 210, and a connector portion 265. The flexible umbilical cord 260 includes a gas (e.g., air or CO2) supply line 240b, a lens cleaning supply line 245b, a suction supply line 250b, an irrigation supply line 255b, a light guide (not shown), and an electrical signal cable (not shown). The connector portion 265 connects a light source 205 in the video processing unit to the light guide when inserted into the video processing unit 210. The light guide extends along the length of the umbilical cord 260 and the endoscope shaft 100a to transmit light to the distal end 100c of the endoscope 100. The connector portion 265 also connects an air pump 215 to the gas supply line 240b in the umbilical cord 260 when inserted into the video processing unit 210.

[0068] A water reservoir or container 270 (e.g., a water bottle) is fluidly connected to the endoscope 100 via a connector portion 265 and an umbilical cord 260. A gas supply line 240c extends from one end of an air gap 275 located between the top 280 (e.g., a bottle cap) of the reservoir 270 and the remaining water 285 in the reservoir to a detachable gas / lens cleaning connector 290 on the outside of the connector portion 265. The detachable gas / lens cleaning connector 290 may be detachable from the connector portion 265 and / or the gas supply line 240c. A gas supply line 240b from the umbilical cord 260 branches in the connector portion 265 to be in fluid communication with the gas supply line 240c and with an air pump 215 at the detachable gas / lens cleaning connector 290. A lens cleaning line 245c extends from one end located at the bottom of reservoir 270 through the top 280 of reservoir 270 to a detachable connector 290 on connector portion 265 identical to that of gas supply line 240c. In other embodiments, these connectors may be separate and / or independent of each other. Connector portion 265 also has a detachable irrigation connector 293 for the irrigation supply line (not shown) extending from an irrigation water source (not shown) to the irrigation supply line 255b in umbilical conduit 260. Detachable irrigation connector 293 may be detachable from connector portion 265 and / or irrigation supply line (not shown). In some embodiments, irrigation water is supplied from a water source (not shown) independent of water reservoir 270 via a pump (e.g., a peristaltic pump). In other embodiments, the irrigation supply line and lens cleaning line 245c may draw water from the same reservoir. The connector portion 265 may also include a detachable suction connector 295 for suction supply lines 250b and 250a, which fluidly connects a vacuum source (e.g., hospital ward suction) (not shown) to the umbilical cord line 260 and the endoscope 100. The detachable suction connector 295 may be detachable from the connector portion 265 and / or the suction supply lines 250b and / or the vacuum source.

[0069] Gas supply line 240b and lens cleaning supply line 245b are fluidly connected to valve well 135 for gas / water valve 140 and are configured such that operation of gas / water valve 140 in the well controls the supply of gas or lens cleaning water to the distal end 100c of endoscope 100. Suction supply line 250b is fluidly connected to valve well 135 for suction valve 145 and is configured such that operation of suction valve in the well controls suction at the working channel 235 of endoscope 100.

[0070] refer to Figure 2This section explains exemplary operation of an endoscope system 200, which includes an endoscope, such as the endoscope 100 described above. Airflow from an air pump 215 in the video processing unit 210 is directed through a connector portion 265 and via a gas supply line 240b in the umbilical conduit 260 to a gas / water valve 140 on the operating handle 115, and via a connector 290 on the connector portion 265 to a water reservoir 270 via a gas supply line 240c. When the gas / water valve 140 is in the neutral position, the user's finger is not on the valve, and air is allowed to flow from the valve to the atmosphere. In the first position, the user's finger is used to block the vent to the atmosphere. Gas is allowed to flow down the gas supply line 240a from the valve 140 and out from the distal end 100c of the endoscope 100, for example, to inflate the patient's treatment area. When the gas / water valve 140 is pressed down to the second position, gas is blocked from leaving the valve, allowing the pressure of the air supplied from the air pump 215 in the water reservoir 270 to rise. Pressure is applied to the water source, causing water to exit from the lens cleaning line 245c, pass through the connector portion 265, the umbilical line 260, through the gas / water valve 140, and down the lens cleaning supply line 245a, where it merges with the gas supply line 240a, and then exits the distal end 100c of the endoscope 100 via the gas / lens cleaning nozzle 220. The air pump pressure can be calibrated to provide lens cleaning water at a relatively low flow rate compared to the irrigation water supply.

[0071] The flow rate of the lens cleaning water is controlled by the gas pressure in the water reservoir 270. As water is expelled from the water reservoir 270 through the lens cleaning line 245c and the gas pressure in the water reservoir 270 begins to drop, the air pump 215 replaces the lost air supply in the water reservoir 270 to maintain a substantially constant pressure, which in turn provides a substantially constant flow rate of lens cleaning water. In some embodiments, a filter (not shown) may be placed in the path of the gas supply line 240c to filter out unwanted contaminants or particles, preventing them from entering the water reservoir 270. In some embodiments, an outflow check valve or other one-way valve configuration (not shown) may be placed in the path of the lens cleaning supply line to help prevent water from flowing back into the reservoir 270 after it has passed through the valve.

[0072] Compared to lens cleaning water, irrigation water typically requires a relatively high flow rate because its primary purpose is to remove debris obstructing the user's view in the patient's treatment area. As described, irrigation is typically achieved using a pump (e.g., a peristaltic pump). In embodiments with a separate water source for irrigation, tubing placed at the bottom of the water source passes through the top of the water source and into the head on the upstream side of the pump. Tubing on the downstream side of the pump is connected via an irrigation connector 293 on connector portion 265 to irrigation supply line 255b in umbilical cord 260 and irrigation supply line 255a of endoscope 100. When irrigation water is needed, fluid is pumped from the water source by operating the irrigation pump (e.g., by pressing a foot switch (not shown)), and the fluid flows through irrigation connector 293, through irrigation supply line 255b in umbilical cord 260, and down the irrigation supply line in the endoscope shaft 100a to the distal end 100c. To balance the pressure in the water source as water is pumped out of the irrigation supply line, a vent (not shown) may be included in the top of the water reservoir. The vent allows atmospheric air into the water source, preventing the buildup of negative pressure that could create a vacuum that would draw unwanted material back from the patient through the endoscope toward the water source. In some embodiments, similar to the lens cleaning line 245c, an outflow check valve or other one-way valve configuration (not shown) may be placed in the path of the irrigation supply line to help prevent backflow into the reservoir after water has passed through the valve.

[0073] Other arrangements using these fluid sources are conceivable, depending on need. For example, in some cases, water used for irrigation and lens cleaning may come from the same container. Some illustrative systems and methods for supplying fluid to an endoscope are described in U.S. Patent Application No. 63 / 419,900, which is commonly assigned and entitled “DEVICES, SYSTEMS, AND METHODS TO SUPPLY FLUIDS TO ANENDOSCOPE”, the disclosure of which is incorporated herein by reference.

[0074] Figure 3 A schematic diagram of another illustrative endoscope system 300 is depicted, which can reduce the frequency of water reservoir replacements and / or reduce the chance of contamination during water reservoir(s) replacement. System 300 may include several advantages over the aforementioned current bottle system. System 300 may include, in relation to... Figures 1 to 2 The described endoscope system and similar components are described; however, not all features can be described or shown herein.

[0075] Typically, system 300 may include a first reservoir 302 and a second reservoir 330. The first reservoir 302 may be configured to supply water or fluid for both rinsing (e.g., via the first reservoir 302) and lens cleaning (e.g., via the second reservoir 330). This allows the use of a single fluid source to supply fluid for both rinsing and lens cleaning. Although not explicitly shown, reservoirs 302, 330 may include printed lines, numbers, or other visual markings to allow a user to easily determine how much fluid remains in reservoirs 302, 330.

[0076] The first reservoir 302 may include a first container 304 configured to contain a first volume of fluid 306. In the illustrated embodiment, the first container 304 is fluidly coupled to an upstream irrigation supply line 328 and configured to supply fluid for irrigation to the endoscope 100. Typically, the irrigation supply line 328 may be a water or fluid supply line or tube for supplying water or other fluids to the endoscope. Additionally, the first container 304 may be optionally fluidly coupled to a second fluid reservoir 330. The second reservoir 330 may include a second container 332 configured to contain a second volume of fluid 334. In the illustrated embodiment, the second container 332 is fluidly coupled to a gas supply line and lens cleaning supply lines 336, 338 and configured to supply fluid for lens cleaning to the endoscope 100. Typically, the lens cleaning supply line 338 may be a water or fluid supply line or tube for supplying water or other fluids to the endoscope. The gas supply line 336 and the lens cleaning supply line 338 may be arranged coaxially. For example, the gas supply line 336 may define a lumen with a diameter large enough to accommodate a smaller diameter lens cleaning line 338 coaxially received within the gas supply line 336, and to supply air to a water source in an annular space surrounding the lens cleaning line 338 to pressurize the second reservoir 330. The lens cleaning supply line 338 may be configured to exit the lumen defined by the coaxial gas supply line 336 with any suitable sealing method (e.g., orifice, fitting, collar, and / or similar construction) for the purpose of changing from a coaxial arrangement to a side-by-side arrangement at the detachable gas / lens cleaning connection connected to the endoscope connector portion 265. In other embodiments, the gas supply line 336 and the lens cleaning supply line 338 may be arranged side-by-side.

[0077] The first container 304 and the second container 332 may be formed of one or more lightweight, flexible materials, such as, but not limited to, low-density polyethylene (LDPE), thermoplastic polyurethane (TPU), silicone, polyethylene terephthalate (PET), aluminum, nylon, polyethylene (PE), plasticized polyvinyl chloride (PVC), or combinations thereof. In some embodiments, the first container 304 and the second container 332 may be completely translucent, completely opaque, or a combination thereof. In some cases, the first container 304 and the second container 332 may be similar to flexible bags used for delivering intravenous fluids in a clinical setting (e.g., intravenous (IV) fluid bags). Such bags may be readily available and familiar to clinicians, as they are widely used in a variety of sizes. The volume of the first container 304 and the second container 332 may be variable. For example, the volume of the first container 304 and / or the second container 332 may be 500 ml or more, 1000 mL or more, 2000 mL or more, 3000 mL, 4000 mL or more, etc. The volume may be less than 500 mL or greater than 4000 mL, depending on the need. One or both of the first reservoir 302 and the second reservoir 330 may be pre-filled with water or other fluids (e.g., before entering the operating room or at the time of manufacture). In some cases, clinicians may select reservoirs 302, 330 from a plurality of available reservoirs of different sizes based on the number and / or type of surgeries expected for a typical day or a particular day. In the illustrated embodiment, the first reservoir 302 may supply fluid to the second reservoir 330. By selecting a first reservoir 302 with a volume large enough to accommodate surgeries throughout the day, the need to replace the sterile fluid source (e.g., the first reservoir 302) can be reduced or eliminated. In some cases, the first reservoir 302 may be used to periodically refill the second reservoir 330. Therefore, the volume of the first reservoir 302 may be larger than the volume of the second reservoir 330, but this is not necessary. It is further envisioned that, in some embodiments, one or both of the first reservoir 302 or the second reservoir 330 may be a rigid bottle.

[0078] It is conceivable that flexible bags can use less plastic (or other materials) than bottles designed to hold a similar amount of fluid. Therefore, using flexible bags as fluid reservoirs 302, 330 can improve the environmental sustainability of system 300. For example, if a user sets up a 3000 mL (3 liter) bag reservoir 302 for the system and therefore does not need to use three separate one-liter bottles, a significant reduction in waste can be achieved. It is further conceivable that when disposed of or discarded, the flexible bag reservoir can occupy a smaller volume than a bottle capable of holding an equivalent volume of fluid.

[0079] The first reservoir 302 may further include one or more ports 308a, 308b, such as, but not limited to, spiked ports or diaphragm ports, which extend from the interior of the first container 304 and are in selective fluid communication with the interior of the container. Ports 308a, 308b may be integrally formed with the first container 304. Ports 308a, 308b may be generally tubular structures, wherein each port 308a, 308b defines a lumen extending therethrough. The lumen of ports 308a, 308b may be configured to selectively fluidly connect the interior of the first container 304 to another component (such as, but not limited to, a fluid or water supply pipe). In some embodiments, ports 308a, 308b may be located adjacent to the bottom end 312 of the first reservoir 302. However, this is not necessary. Ports 308a, 308b may be located at other locations as needed. If ports 308a and 308b are located outside the bottom 312 of the first container 304, a suction tube or tube extension may be required to access the fluid at the bottom of the first container 304. In some cases, at least one port 308b may be configured to connect to an upstream flushing line (or water supply line) 328, while another port 308a may be configured to allow a user to add additives to the fluid 306. In other examples, the upstream flushing line 328 may connect to the first port 308a, while the second reservoir 330 is in fluid communication with the second port 308b. Although the first reservoir 302 is shown to include two ports 308a and 308b, the first reservoir 302 may include one or more ports as needed.

[0080] Although not explicitly shown, ports 308a and 308b may each include a removable cap or seal configured to form a fluid-impermeable seal with ports 308a and 308b. The removable cap or seal helps maintain the sterility of ports 308a and 308b. The removable cap or seal can be attached to the free end of ports 308a and 308b using several different techniques. For example, the cap or seal can be attached to ports 308a and 308b using threaded engagement, friction fit, snap-fit, etc. In other instances, the cap or seal can be removed by a torsional movement configured to disconnect the cap or seal from ports 308a and 308b. Once the cap or seal has been removed, ports 308a and 308b can be pierced using a spiked tip or spiked port adapter 310 connected to the upstream flushing line 328. For example, in addition to a removable cap or seal, ports 308a and 308b may include internal seals disposed within the lumens of ports 308a and 308b, which may be punctured or penetrated by the spike port adapter 310. The internal seals may be configured to prevent fluid 306 from leaking from the first container 304 before the spike port adapter 310 is inserted into ports 308a and 308b. In some embodiments, the internal seals may be self-sealing, preventing fluid leakage from ports 308a and 308b when the spike port adapter 310 is removed. The outer surface of the spike port adapter 310 may form an interference fit with the inner surface of ports 308a and 308b. The fit and / or connection between the spike port adapter 310 and ports 308a and 308b may be sufficient to hold them in place when the flushing supply tube 328, branch connector 350, and / or other piping assemblies are connected to the spike port adapter 310. It is conceivable that the spiked port adapter 310 could be inserted into one of ports 308a and 308b using commonly used aseptic techniques (such as those used with IV fluid bags). This could help reduce the risk of infection by maintaining sterile components and preventing contaminants from being introduced into fluid 306. It is further conceivable that additives could be added to fluid 306 via one of ports 308a and 308b using similar aseptic techniques.

[0081] The first reservoir 302 may include a handle 316 positioned adjacent to its top portion 314. The handle 316 may define an opening or through-hole 318 for receiving a hand or hook to carry the first reservoir 302. In some cases, the handle 316 may include an undulating surface configured to provide a more ergonomic grip for the user. It is conceivable that the handle 316 may be formed from a material similar to or different from the first container 304, as needed. In some examples, the handle 316 may be formed from polyethylene terephthalate (PET), polypropylene (PP), etc. The handle 316 may allow the first reservoir 302 to be suspended on a hook, such as, but not limited to, an IV stand. Suspending the first reservoir 302 allows it to be positioned above the height of the endoscope cart, enabling the user to see the fluid level 306 at any time. This can help clinicians avoid fluid depletion during surgery. Additionally, raising the reservoir eliminates the need for clinicians to bend or lean forward during the setup of system 300 and / or replacement of the first reservoir 302. In some cases, the pressure head generated by raising the first reservoir 302 can enable rapid pre-charging of the irrigation circuit (and / or lens cleaning circuit, if so connected), saving time during setup. It is further conceivable that suspending the first reservoir 302 on a hook or IV stand allows it to be positioned away from expensive capital equipment, thereby reducing or eliminating the possibility of fluid inadvertently flowing onto or onto capital equipment and causing damage or destruction.

[0082] The first reservoir 302 is fluidly connected to the lumen of the upstream irrigation supply line 328. The upstream irrigation supply line 328 extends from a second end region 322 located outside the container 304 and within the pump head 324 of the peristaltic irrigation pump 315 to a first end 320. The first end 320 of the upstream irrigation supply line 328 is coupled to a spiked port adapter 310, which is further configured to extend through the lumen of port 308b and pierce a seal within the lumen of port 308b to fluidly connect the interior of the container 304 to the lumen of the upstream irrigation supply line 328. The second end of the upstream irrigation supply line 328 is configured to fluidly connect to the irrigation lumen of the endoscope 100. When flushing water is required, fluid is pumped from the first container 304 by operating the flushing pump 315 (e.g., by pressing a foot switch (not shown)), and the fluid flows from the first reservoir 302 through the upstream flushing supply line 328 and branch connector 350, through the downstream flushing supply line 255c, through the flushing connector 293, through the flushing supply line 255b in the umbilical line 260, and down along the flushing supply line 255a in the endoscope shaft 100a to the distal end 100c.

[0083] The downstream irrigation supply line 255c may include a loaded check valve or flow control valve 326 positioned in series with the downstream irrigation supply line 255c. The flow control valve 326 can prevent fluid from unintentionally flowing from the first container 304 into the endoscope 100. In some cases, the flow control valve 326 can be configured to open when the pressure in the downstream irrigation supply line 255c reaches a predetermined minimum pressure. It is conceivable that the predetermined minimum pressure may be greater than the head generated by the height difference between the first reservoir 302 and the irrigation pump 315. The flow control valve 326 can also prevent fluid leakage from the downstream irrigation supply line 255c when the endoscope 100 is changed between patients and the tubing kit connector is disconnected from the endoscope water port.

[0084] In some embodiments, the irrigation pump 315 may be omitted. For example, the reservoir 302 may be inserted into a compression sleeve. When irrigation fluid is desired, the compression sleeve can be activated to apply pressure to the outer surface of the reservoir 302 and provide the necessary pressure for performing irrigation at the distal end of the endoscope 100. In another embodiment, the reservoir 302 may be inserted into a compression sleeve that applies a constant pressure to the reservoir 302, wherein a flow switch is positioned along the irrigation supply line 328 to provide binary control of the irrigation flow.

[0085] The second reservoir 330 may further include one or more ports 340, such as, but not limited to, spiked ports or diaphragm ports, extending from the interior of the second container 332 and in selective fluid communication with the interior of the second container. Ports 340 may be integrally formed with the second container 332. Ports 340 may be generally tubular structures, wherein port 340 defines a lumen extending therethrough. The lumen of port 340 may be configured to selectively fluidly connect the interior of the second container 332 to another component (such as, but not limited to, a fluid / water / gas supply line). In some cases, port 340 may be configured to connect to a gas supply line 336 and a lens cleaning supply line 338. In some embodiments, port 340 may be positioned adjacent to the bottom end 342 of the second reservoir 330. However, this is not required. Port 340 may be positioned at other locations as needed. If port 340 is located outside the bottom 342 of the second container 332, a draw tube or tube extension (e.g., connected to the lens cleaning supply line 338) may be needed to access the fluid at the bottom of the second container 332. Although the second reservoir 330 is shown to include one port 340, the second reservoir 330 may include more than one port as needed.

[0086] Although not explicitly shown, port 340 may include a removable cap or seal configured to form a leak-proof seal with port 340. The removable cap or seal helps maintain the sterility of port 340. The removable cap or seal can be attached to the free end of port 340 using several different techniques. For example, the cap or seal can be attached to port 340 using threaded engagement, friction fit, snap-fit, etc., or it can be securely attached using several techniques such as adhesive or solvent bonding. In other instances, the cap or seal can be removed by a torsional movement configured to disconnect the cap or seal from port 340. Once the cap or seal has been removed, port 340 can be pierced with a spiked end or spiked port adapter (not explicitly shown) connected to gas supply line 336 and lens cleaning supply line 338. For example, in addition to the removable cap or seal, port 340 may include an internal seal disposed within the lumen of port 340, which can be pierced or penetrated by the spiked port adapter. An internal seal may be configured to prevent fluid 334 from leaking from the second container 332 before the spike port adapter is inserted into port 340. In some embodiments, the internal seal may be self-sealing, preventing fluid leakage from port 340 when the spike port adapter is removed. The outer surface of the spike port adapter may form an interference fit with the inner surface of port 340. The fit and / or connection between the spike port adapter and port 340 may be sufficient to hold it in place when the gas supply line 336 and fluid supply line 338 and / or other line kits are connected to the spike port adapter. It is envisioned that the spike port adapter may be inserted into port 340 using commonly used aseptic techniques, such as those used with IV fluid bags. This can help reduce the risk of infection by maintaining sterile components and preventing contaminants from being introduced into fluid 334. It is further envisioned that, if desired, additives may be added to fluid 334 via port 340 using similar aseptic techniques. In some cases, additional coupling mechanisms may be used as needed to connect the gas supply line 336 and the lens cleaning supply line 338 to the port 340. Some illustrative coupling mechanisms may include, but are not limited to, threaded engagement, snap-fit, friction engagement, quick-connect couplings, etc., or may be used to securely connect using several techniques (such as adhesive or solvent bonding).

[0087] A gas supply line 336 extends from a second end outside the second container 332 to a port 340. The gas supply line 336 may extend into the interior of the second container 332 and terminate within a reservoir gap (e.g., above the level of fluid 334). However, in some cases, the gas supply line 336 may terminate within fluid 334. A lumen extends through the gas supply line 336 to receive air and / or gas flow therethrough. The lumen of the gas supply line 336 may be in operative fluid communication with the top portion of the interior of the second container 332. A lens cleaning supply line 338 extends from a second end outside the second reservoir 330 to a first end in fluid communication with the bottom portion 342 of the second container 332. In some embodiments, the lens cleaning supply line 338 may terminate at port 340. A lumen extends through the lens cleaning supply line 338 to receive fluid flow therethrough. The lumen of the lens cleaning supply line 338 is selectively in operative fluid communication with the bottom portion 342 of the second container 332. In the illustrated embodiment, the gas supply line 336 and the lens cleaning supply line 338 can be connected to the second container 332 via a single or common opening (e.g., port 340). For example, the gas supply line 336 and the lens cleaning supply line 338 can be arranged coaxially. However, this is not required. In some cases, the gas supply line 336 and the lens cleaning supply line 338 can extend side by side, or can be connected to the second container 332 separately at different locations.

[0088] The second container 332 may further include a first fluid inlet 344 and a second fluid inlet 346. While the first fluid inlet 344 and the second fluid inlet 346 are shown adjacent to or extending from the top portion 348 of the second container 332, the first fluid inlet 344 and / or the second fluid inlet 346 may be positioned at other locations around the second container 332 as needed. In some embodiments, the first fluid inlet 344 and / or the second fluid inlet 346 may be tubular members formed as a single integral structure with the second container 332. In other embodiments, the first fluid inlet 344 and / or the second fluid inlet 346 may include tubular components releasably coupled to ports (similar in form and function to port 340) formed in or with the container 332.

[0089] The first fluid inlet 344 may be in selective fluid communication with the first reservoir 302. For example, the branch connector 350 may be positioned in series with the upstream flushing line 328. In some embodiments, the branch connector 350 may be a "Y" type connector or a "T" type connector having an inlet branch 356 defining a first fluid inlet, a first outlet branch 352 defining a first fluid outlet, and a second outlet branch 354 defining a second fluid outlet. However, it is contemplated that the branch connector 350 may include more than one fluid inlet and fewer than two or more than two fluid outlets, if so required.

[0090] Branch connector 350 can be positioned in series with upstream flushing line 328 such that inlet branch 356 and first outlet branch 352 are fluidly connected to the lumen of upstream flushing line 328. Fluid can flow from first reservoir 302 through upstream flushing line 328, through branch connector 350, and again through upstream flushing line 328. Branch connector 350 can be positioned such that inlet branch 356 is upstream of outlet branches 352, 354 relative to flushing fluid flow. In some embodiments, branch connector 350 and spike port adapter 310 can be molded or formed as a single integral structure. This is contemplated to reduce connection points in the fluid loop. In this case, first end 320 of flushing supply line 328 can be fluidly connected to first outlet branch 352 of branch connector 350.

[0091] The second outlet branch 354 may be fluidly connected to the first fluid inlet 344 of the second reservoir 330. A flow control mechanism (such as, but not limited to, a check valve 358) may be located between the second fluid outlet of the second outlet branch 354 and the first fluid inlet 344 of the second reservoir 330 to selectively connect the second container 332 to the first container 304. The check valve 358 may be configured to open to allow fluid to selectively flow from the first reservoir 302 to the second reservoir 330, while preventing fluid (e.g., gas, water, or other fluid) from leaving the second container 332 and entering the flushing supply line 328 and / or the first container 304. In some embodiments, the check valve 358 may be replaced by a clamp that can compress the first fluid inlet 344 to selectively isolate the second container 332 from the first container 304, and be removed to selectively connect the second container 332 to the first container 304. In yet other embodiments, the check valve 358 may be replaced by a spring-loaded valve, a plug valve, or other two-way valve. When it is desired to add fluid from the first reservoir 302 to the second reservoir 330, the check valve 358 (or other flow control mechanism) can be opened or released. The fluid can then be diverted at least partially from the flushing supply line 328 via the second outlet branch 354 of the branch connector 350 and enter the second container 332 along the flow path 360. Fluid can be added to the second container 332 as needed, either while the flushing pump 315 is operating or when the flushing pump 315 is idle.

[0092] The second fluid inlet (or gas supply line) 346 of the second container 332 may be an alternative gas supply line configured to connect to an alternative gas supply (e.g., a CO2 hospital ward gas source). The second fluid inlet 346 may extend from a second end outside the second container 332 to a first end connected to the second container 332. The alternative gas supply may be used to pressurize the second container 332 to supply lens cleaning water to the endoscope 100 and / or to provide gas injection. A lumen extends through the second fluid inlet 346 to receive the gas flow passing through it. The lumen of the second fluid inlet 346 is in operative fluid communication with the top portion of the second container 332. The flow of CO2 within the system 300 may be similar to the flow described above. For example, in a neutral state, CO2 gas flows into the second container 332 through the second fluid inlet 346, upward along the gas supply line 336 to the connector portion 265, upward along the gas supply line 240b in the umbilical conduit 260, and is discharged to the atmosphere through the gas / water valve 140. In the first position, the user seals the vent in the gas / water valve 140, and CO2 gas flows into the second container 332 through the second fluid inlet 346, ascends along the gas supply line 336 to the connector portion 265, flows through the gas / water valve to the gas supply line 240a in the endoscope shaft 100a, and exits the gas / lens cleaning nozzle 220 at the distal end 100c. In the second position, the user presses the valve 140 to the bottom of the valve well 135 while keeping the vent in the gas / water valve closed. The second position blocks the supply of CO2 gas to both the atmosphere and the gas supply line 240a in the endoscope 100, and opens the gas / water valve 140 to allow lens cleaning water to pass through the lens cleaning supply line 245a in the endoscope shaft 100a and exit the gas / lens cleaning nozzle 220 at the distal end 100c. The gas (pressure) in the second reservoir 330 is maintained by delivering gas via the second fluid inlet 346. It is conceivable that the one-way valve 358 is in a closed configuration during CO2 gas delivery to allow pressurization of container 332. In some instances, the one-way valve 358 may be configured to close without user intervention in response to the delivery of CO2 to the second container 332. In some embodiments, system 300 may include a branch connector (such as, but not limited to, a "Y" or "T" connector) at the second fluid inlet 346 to allow air or CO2 for pressurization or injection. It is further conceivable that the second fluid inlet 346 may include a pressure relief valve 362 (such as, but not limited to, a 3-way stopcock valve, a clamp, or a spring-loaded valve) to release pressure within the second container 332 and / or prevent pressurized gas from flowing into the second container 332 during refilling of the second container 332, during surgical transitions, and / or during device transitions.

[0093] It is conceivable that using a flexible bag instead of a rigid bottle for the second reservoir 330 could reduce or eliminate the risk of air leakage from the bottle and cap connection. This would eliminate the need for clinicians to attempt to remedy a leak by adjusting the cap and bottle assembly, or to discard the cap and / or bottle if a leak is irreparable.

[0094] Because the pressurized second reservoir 332 is fluidly isolated from the first reservoir 304 when the one-way valve 358 is closed, it is conceivable that a clinician could replace the first reservoir 302 with a new (full) reservoir without interrupting patient insufflation. Interruption of patient insufflation could lead to disruption of the positioning of the endoscope 100 within the body. In current one- or two-bottle systems, it may not be possible to replace the water reservoir without interrupting patient insufflation.

[0095] If it is necessary to replace the first reservoir 302 with a new full bag, for example when the first reservoir 302 is empty or nearly empty, the user can suspend the new bag near the first reservoir 302 to be replaced. The user can then disengage the spiked port adapter 310 from port 308b and insert the spiked port adapter 310 into the port of the new bag. This can be performed without requiring the clinician to bend or lean to access the first reservoir 302. Port 308b is self-sealing to prevent fluid leakage from the first reservoir 302 being replaced. This method of replacing the first reservoir 302 can have a lower risk of introducing contaminants into the system compared to conventional bottle systems. For example, the replacement method described herein allows the first reservoir 302 to be replaced without suspending the tubing over the cap (as is done in bottle systems). Furthermore, the system 300 can remain substantially closed while the first reservoir 302 is being replaced.

[0096] Figure 4This is a schematic perspective view of an illustrative trolley 400 that can be used to hold or mount capital equipment during endoscopic procedures. The illustrative trolley 400 may include multiple shelves 402a-e movably or permanently secured to a frame 404. The trolley 400 may include any desired number of shelves 402a-e. Shelves 402a-e may be configured to hold equipment thereon. For example, one or more processing units 210 may be positioned on one or more of the shelves 402a-e. Shelves 402a-e may include different configurations to accommodate different components of the endoscope system 200. For example, some shelves 402c-e may be generally planar to allow easy positioning and / or removal of equipment thereon. Other shelves 402a may include a raised perimeter 418 defining an internal cavity or recess 420. This helps prevent items from falling off the shelves 402a-e. In other examples, shelf 402b may include raised lips 422 along one or more of its edges to facilitate gripping of shelf 402b. Each shelf 402a-e may include an upper surface 424 on which the device may be positioned.

[0097] The trolley 400 may further include a plurality of wheels 406 to facilitate positioning of the trolley 400 within the operating room. In some cases, one or more of the wheels 406 may include a locking mechanism 408 configured to prevent movement of the wheels 406 and / or the trolley 400. One or more arms or levers 410 may extend from the frame 404. The levers 410 may be configured to mount various components thereto, such as, but not limited to, the display unit 412. In some cases, the levers 410 may include features configured to receive tube kits, endoscope handles, etc. Alternatively or additionally, mounting features 414 for receiving tube kits, endoscope handles, etc., may be mounted to one or more of the shelves 402a-e and / or the frame 404. The trolley 400 may include one or more handles, push rods, or grips 416. The levers 416 may be formed as a single integral structure with one of the shelves 402a-e or may be coupled to one of these shelves. Alternatively or additionally, the rod 416 may be formed as a single integral structure with the frame 404 or connected to the frame. It should be understood that the trolley 400 may include additional features not explicitly described herein. Furthermore, the shelves 402a-e, the frame 404, the rod 410, and / or other features may be arranged in any desired manner.

[0098] As described herein, it may be desirable to install one or more of the storage devices 302, 330 from the trolley 400 or to install one or more storage devices to a device connected to the trolley. Figure 5This is a side view of an illustrative mounting feature 426 for holding or receiving an endoscope handle 115 therein. Mounting feature 426 may include a body portion 434 of an arm or lever 410 coupled to a trolley 400. Mounting feature 426 may include a first channel 428, the size and shape of which are determined to receive an umbilical cord 260. The umbilical cord 260 may rest in the first channel 428, and the handle 115 may extend generally parallel to the longitudinal axis of mounting feature 426. In some cases, mounting feature 426 may include a second channel 430 (see, for example...). Figure 6 The second channel is configured to receive the endoscope handle 115 therein. The second channel 430 may extend generally orthogonally to the first channel 428. In some cases, the mounting feature 426 may further include a third channel 432 that extends generally alongside and parallel to the first channel 428. The third channel 432 may be configured to receive tubing assemblies, such as, but not limited to, irrigation tubing and / or gas / lens cleaning tubing.

[0099] Figure 6 It includes illustrative connecting member 500. Figure 5 A perspective view illustrating the mounting feature 426, showing the connecting member used to connect or secure the fluid reservoir 302 to the trolley 400. The connecting member 500 may be suspended above or extend around the body portion 434 of the connecting member 500. In some examples, the connecting member 500 may be at least partially positioned within a third channel 432. It is contemplated that at least partially positioning the connecting member 500 within the third channel 432 can help prevent accidental removal of the connecting member 500 from the mounting feature 426. For example, the connecting member 500 may rest within a valley of the channel 432, with the sidewalls of the channel providing a mechanical stop to limit lateral movement of the connecting member 500. In some cases, the connecting member 500 may be at least partially positioned within a first channel 428 and / or a second channel 430.

[0100] The connecting member 500 may be formed of an elongated body or body portion 502 and a hook area or fastening member 504. In some embodiments, the elongated body 502 may form a ring 506 configured to extend around the outer surface of the body portion 434 of the mounting feature 426. It is contemplated that the ring 506 may have a size substantially the same as the perimeter of the outer surface of the body portion 434, such that all or most (e.g., greater than 60%) of the ring 506 contacts the outer surface of the body portion 434. In other examples, the ring 506 may be larger than the perimeter of the outer surface of the body portion 434, such that the ring 506 is loosely suspended on the mounting feature 426, or less than 60% of the ring 5014 contacts the perimeter of the outer surface of the body portion 434. In other embodiments, the elongated body 502 may not form a complete ring. For example, the first end of the elongated body 502 may be connected to or extend from the hook region 504, and the second end of the elongated body 502 may be hooked or looped on the body portion 434 of the mounting feature 426, wherein the second end of the elongated body 502 is not connected to or secured relative to the rest of the elongated body 502.

[0101] The elongated body 502 can take many different forms. In one illustrative example, the elongated body 502 can be a flexible elastic band made of natural rubber, ethylene propylene diene monomer (EPM, EPDM), synthetic polyisoprene, silicone resin, elastomer, other flexible polymers, etc. In this case, the elongated body 502 can be a ring 506, which is configured to be stretched or expanded to be positioned over the body portion 434 of the mounting feature 426 and return to a more relaxed state, but not necessarily a completely relaxed state, around the perimeter of the outer surface of the body portion 434. When the elongated body 502 is formed of a more flexible or compliant material, it is conceivable that the hook region 504 can be formed of a different material that is more rigid than the elongated body 502.

[0102] A hook region 504 may extend from a first end region 508 to a second end region 510. The first end region 508 may be configured to fasten or engage with a ring 506 of the connecting member 500. In some examples, the first end region 508 may be wound within the ring 506 around the elongated body 502 of the connecting member 500. However, the hook region 504 may be engaged with the connecting member 500 using other techniques, such as, but not limited to, clamps, clips, adhesives, etc. In other examples, the first end region 508 may have a curved region hooked onto the elongated body 502 of the connecting member 500. In other embodiments, the hook region 504 may be formed as a single integral structure with the elongated body 502. The second end region 510 may include a curved region 512 configured to receive a handle 316 of the reservoir 302. The curved region 512 may have a generally "U" or "J" shaped form, such that the handle 316 can rest within the interior of the curved region 512. The hook region 504 can be formed from a variety of different materials, including: metallic materials, such as, but not limited to, aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as, but not limited to, acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyether ether ketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nano clay, graphene, talc, kaolin, wollastonite, etc.

[0103] In some embodiments, the connecting member may be attached to the mounting feature 426 before the hook region 504 and / or the reservoir are attached to the connecting member 500. For example, the connecting member 500 may be secured around the mounting feature 426, and then the hook region 504 may be attached to the connecting member. Alternatively, the hook region 504 may be attached to the connecting member 500 (or formed with the same structure as the connecting member) before the connecting member 500 is secured to the mounting feature 426.

[0104] To suspend the reservoir 302 on the mounting feature 426, a connecting member 500 may be disposed around the body portion 434 of the mounting feature 426. The connecting member 500 may be oriented such that the hook region 504 is suspended in a downward direction. A handle 316 or other suspension feature may be disposed above the hook region 504, allowing the reservoir 302 to be suspended on the connecting member 500. It is envisioned that suspending the reservoir 302 on the mounting feature 426 would allow clinicians to clearly see the remaining fluid in the reservoir 302 while keeping the reservoir 302 in a minimally obstructive position.

[0105] It is conceivable that other structures or configurations could be used to suspend the reservoir on mounting feature 426. Figure 7This is a perspective view of another illustrative connecting member 550. The connecting member 550 may include an elongated body 552 extending from a first end 554 to a second end 556. The elongated body 552 may include a flexible wire or filament 558 extending from the first end 554 to the second end 556. The wire 558 can be configured to move into a variety of different configurations. The wire 558 may be formed of a material containing metals (such as, but not limited to, aluminum and copper), which allows the wire 558 to be repeatedly bent and de-bent (e.g., plastically deformed) without breaking. When moved into a new configuration, the wire 558 can retain its shape without any additional means of securing it. In some examples, the wire 558 may be formed of a polymeric material or natural fibers. The wire 558 may be coated with a coating 560. The coating 560 may be formed of a polymeric material, such as, but not limited to, silicone. It is conceivable that the coating 560 can (compared to using only the wire 558) increase the surface area of ​​the connecting member 550 to improve the grip and maneuverability of the connecting member 550. In some cases, coating 560 can increase the friction between the connecting member 550 and the mounting feature 426, allowing the connecting member 550 to better grip the mounting feature 426.

[0106] The connecting member 550 is movable between an elongated configuration (not explicitly shown) and a torsional configuration, in which the elongated body 552 does not cross itself, and in the torsional configuration, it is configured to form a ring 562. To suspend the reservoir 302 on the mounting feature 426, the connecting member 550 may initially be in the elongated configuration, with a first end 554 positioned on a first side of the mounting feature 426 and a second end 556 positioned on a second side of the mounting feature 426, each of the first end 554 and the second end 556 being above the mounting feature 426. One or both of the first end 554 or the second end 556 may be twisted or wound relative to the other to form a torsional region 564. The torsional region 564 may be axially offset from the first end 554 and the second end 556, such that in the torsional configuration, the connecting member 550 includes a ring 562, a torsional region 564, a first free end region 566, and a second free end region 568. The length of the first free end region 566 and / or the length of the second free end region 568 can vary depending on the position of the torsion region 564. Furthermore, the diameter or cross-sectional dimension of the ring 562 can vary depending on the position of the torsion region 564. For example, the larger the diameter of the ring 562, the shorter the length of the first free end region 566 and / or the second free end region 568 can be. The torsion region 564 can be positioned such that a portion of the mounting feature 426 and the handle 316 of the reservoir 302 is disposed within the ring 562. Alternatively, the handle of the reservoir 302 can be suspended on a hook 570, which is similar in form and function to the hook region 504 described herein. If it is desired to remove the connecting member 550 from the mounting feature 426 (or other parts of the trolley 400), the torsion action of the first end 554 and / or the second end 556 can be reversed to move the connecting member 550 into an elongated configuration. Once the torsion zone 564 has been removed, the connecting member 550 can be disengaged from the mounting feature 426 and / or the handle 316.

[0107] In some embodiments, the connecting member 550 may further include a hook or hook-like member 570 releasably coupled to the connecting member. The hook 570 may extend from a first end region 572 to a second end region 574. The first end region 572 may be configured to secure or engage with a loop 562 of the connecting member 550. In some examples, the first end region 572 may be wound within the loop 562 around the elongated body 552 of the connecting member 550. However, the hook 570 may be coupled to the connecting member 550 using other techniques, such as, but not limited to, clamps, clips, adhesives, etc. In other examples, the first end region 572 may have a curved region hooked onto the elongated body 552 of the connecting member 550. The second end region 574 may include a curved region 576 configured to receive a handle 316 of the reservoir 302. The curved region 576 may have a generally “U” or “J” shape, such that the handle 316 can rest within the interior of the curved region 576. Hook 570 can be formed from a variety of different materials, including: metallic materials, such as but not limited to aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as but not limited to acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyether ether ketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nano clay, graphene, talc, kaolin, wollastonite, etc.

[0108] When using hook 570 to hold or receive reservoir 302, the connecting member 550 can be attached to mounting feature 426 before hook 570 and / or reservoir are attached to connecting member. For example, connecting member 550 can be secured around mounting feature 426, and then hook 570 can be attached to connecting member. Alternatively, hook 570 can be attached to connecting member 550 before connecting member 550 is secured to mounting feature 426. Once hook 570 is attached to connecting member 550, reservoir 302 can be suspended on hook 570.

[0109] Figure 8A It is a perspective view of another illustrative connecting member 600 in the first elongated configuration, and Figure 8B It is in the second ring configuration Figure 8A A perspective view of an illustrative connecting member 600. The connecting member 600 may include an elongated body 602 extending from a first end 604 to a second end 606. A first side of the elongated body 602 may include a plurality of teeth 608. The teeth 608 may be raised areas configured to engage with a pawl 610 disposed within an opening 614 of an insert head 612. The first end 604 of the elongated body 602 may be configured to be inserted into the opening 614 of the insert head 612. The pawl 610 may allow the first end 604 of the elongated body 602 to move along... Figure 8BThe first direction, indicated by arrow 616, moves through the opening 614. However, once the pawl 610 engages with at least the first tooth of the plurality of teeth 608, movement of the first end 604 in a second direction opposite to the first direction can be prevented. The pawl 610 can engage with one or more teeth 608 to hold the connecting member 600 in a position such as Figure 8B The ring configuration is shown. It is conceivable that the connecting member 600 may include other structures configured to maintain the connecting member 600 in the ring configuration. For example, the insertion head 612 may include a protrusion configured to engage with one or more recesses formed in the elongated body 602.

[0110] The connecting member 600 can be in the first generally elongated configuration ( Figure 8A ) and the ring-forming configuration used to form ring 618 ( Figure 8B The device 302 can be moved between the two. To suspend the reservoir 302 on the mounting feature 426, the connecting member 600 can initially be in an elongated configuration. A first end 604 (or a second end 606) of the elongated body 602 can be inserted into an opening 318 through the handle 316 of the reservoir 302. The first end 604 can then be positioned on a first side of the mounting feature 426, and the second end 606 on a second side of the mounting feature 426, with each of the first end 604 and the second end 606 above the mounting feature 426. The first end 604 can then be inserted through an opening 614 through the insert head 612 until at least one tooth 608 engages with a pawl 610. The pawl 610 can engage with one or more teeth 608 to hold the connecting member 600 in a loop configuration. In the loop configuration, the first end 604 of the elongated body 602 can extend from the insert head 612. The length of the elongated body 602 extending from the insert head 612 can be trimmed or removed, or left intact. The diameter or cross-sectional dimensions of the ring 618 can vary depending on how far the first end 604 is pulled through the insert head 612. For example, the larger the diameter of the ring 618, the shorter the length of the elongated body 602 extending from the insert head 612 can be. If it is desired to remove the connecting member 600 from the mounting feature 426 (or other parts of the trolley 400), the elongated body 602 can be cut or severed. In some cases, the pawl 610 may include a release mechanism configured to disengage the pawl 610 from the teeth 608 to allow the first end 604 to retract through the pawl 610 without causing mechanical damage to the connecting member 600. Once the first end 604 has been retracted from the insert head 612 or the connecting member 600 has been cut, the connecting member 600 can be disengaged from the mounting feature 426 and / or the handle 316.

[0111] The connecting member 600 can be formed of various materials, including: metallic materials, such as but not limited to aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as but not limited to acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyether ether ketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nano clay, graphene, talc, kaolin, wollastonite, etc.

[0112] In some embodiments, the connecting member 600 may further include a hook or hook-like member releasably connected to the connecting member. The hook may be similar in form and function to the hook described above. Figure 7 The hook 570 is described. Typically, the hook can extend from a first end region to a second end region. The first end region can be configured to secure or connect to a ring 618 of the connecting member 600. The second end region may include a curved region configured to receive a handle 316 of the reservoir 302. The curved region may have a generally "U" or "J" shape, such that the handle 316 can rest within the interior of the curved region. The hook can be formed from a variety of different materials, including: metallic materials, such as, but not limited to, aluminum, stainless steel, metal alloys, etc.; polymeric materials, such as, but not limited to, acrylonitrile butadiene styrene (ABS), polyimide, polyamide-imide (PAI), polyamide, polyetheretherketone (PEEK), etc.; or polymeric materials reinforced with glass fiber, mica powder, nanoclay, graphene, talc, kaolin, wollastonite, etc.

[0113] When using a hook to hold or receive the reservoir 302, the connecting member 600 can be attached to the mounting feature 426 before the hook and / or reservoir are attached to the connecting member. For example, the connecting member 600 can be secured around the mounting feature 426, and then the hook can be attached to the connecting member. Alternatively, the hook can be attached to the connecting member 600 before the connecting member 600 is secured to the mounting feature 426. Once the hook is attached to the connecting member 600, the reservoir 302 can be suspended on the hook.

[0114] Figure 9This is a perspective view of another illustrative mounting feature 414, which can be used to hold or accommodate the endoscope 100 when it is not in use. Mounting feature 414 may include a body portion 440 having a cavity or opening 442 extending from a first end 444 to a second end 446 of the body portion 440. The diameter or cross-sectional dimension of the cavity 442 may decrease from the first end 444 to the second end 446 of the body portion 440. For example, the size and shape of the cavity 442 may be determined to be a mirror image of the tapered profile of the endoscope handle 115. This allows the outer surface of the endoscope handle to frictionally engage the inner surface of the body portion 440 to allow insertion of the endoscope handle into the cavity 442 while providing a mechanical stop. In some cases, mounting feature 414 may include a lateral slot 448 extending through the sidewall of the body portion 440. The lateral slot 448 allows the endoscope handle 115 to be inserted laterally into the mounting feature 414, rather than feeding the entire length of the endoscope 100 through the lumen 442.

[0115] In some embodiments, the connecting member 800 may be inserted into the cavity 442 of the mounting feature 414 to secure the fluid reservoir 302 relative to the trolley 400. Figure 10This is a perspective view of an illustrative connecting member 800 disposed within the cavity 442 of mounting feature 414. The connecting member 800 may include an anchoring member 802 extending from a first end 804 to a second end 806. In some embodiments, the body portion or anchoring member 802 may be substantially solid. In other embodiments, the anchoring member 802 may be hollow or define a cavity extending therethrough. The anchoring member 802 may have a first outer diameter or cross-sectional dimension 808 adjacent to its first end 804 and a second diameter or cross-sectional dimension 810 adjacent to its second end 806. The first diameter 808 may be larger than the second diameter 810. In some cases, the anchoring member 802 may transition from the first diameter 808 to the second diameter 810 in a gradually tapering manner at a transition region 812. In other embodiments, the anchoring member 802 may transition from the first diameter 808 to the second diameter 810 in an abrupt staircase manner. In some cases, the transition region 812 may appear at an intermediate location between the first end 804 and the second end 806. The first diameter 808 can be larger than the diameter of the cavity 442 at the second end 446 of the body portion 440 adjacent to the mounting feature 414. This prevents the connecting member 800 from passing through the cavity. However, the first diameter 808 of the anchoring member 802 can be smaller than the diameter of the cavity 442 at the first end 444 of the body portion 440 adjacent to the mounting feature 414. This allows the connecting member 800 to be inserted into the cavity 442 of the body portion 440 of the mounting feature 414. The second diameter 810 of the anchoring member 802 can be smaller than the diameter of the cavity 442 at the second end 446 of the body portion 440 adjacent to the mounting feature 414. This allows the second end 806 of the anchoring member 802 of the connecting member 800 to extend beyond the second end 446 of the body portion 440 of the mounting feature 414. However, this is not necessary. In some cases, the second diameter 810 of the anchoring member 802 may be approximately equal to or greater than the diameter of the cavity 442 at the second end 446 adjacent to the mounting feature 414.

[0116] The fastening member 814 can be connected to the second end 806 of the anchoring member 802 via the fastening member 816. In some cases, the fastening member 816 can be a mechanical connection structure, such as, but not limited to, a clamp, screw, hook, etc. In other examples, the fastening member 816 can be fastened by adhesive, welding, brazing, soldering, etc. In yet another example, the fastening member 814 can be formed as a single integral structure with the anchoring member 802, and the fastening member 816 can be omitted.

[0117] In the illustrated embodiment, the fastening member 814 may include a hook or ring 818 comprising a movable door 820 configured to engage a nose 822. The door 820 may be pressed inward to allow another component to enter the interior of the ring 818, while the nose 822 prevents the door 820 from accidentally opening in the opposite direction to its interior. It is contemplated that the fastening member 814 may take other forms as needed. Some illustrative fastening members 814 may include, but are not limited to, lobster hooks, S-hooks, spring rings, hooks, loops, ropes, lines, etc.

[0118] To suspend the reservoir 302 on the connecting member 800, the connecting member 800 can be inserted into the cavity 442 of the mounting feature 414. The handle 316 or suspension mechanism of the reservoir 302 can then be suspended on the fastening member 814. In the illustrated embodiment, the door 820 can be actuated to allow the handle 316 to be received within the fastening member 814. In the absence of the door 820 or other actuable latch, the handle 316 can be suspended on a curved hook.

[0119] Figure 11 This is a perspective view of another illustrative connecting member 900 configured to be secured relative to the connector portion 265 of the umbilical conduit 260. The connecting member 900 may include an elongated body 902 extending from a first end 904 to a second end 906. The elongated body 902 may be formed of a flexible or bendable material such that it can be positioned above the front or upper edge of the connector portion 265, with the free ends 904, 906 suspended below the connector portion 265. The elongated member 902 may be formed of materials such as, but not limited to, low-density polyethylene (LDPE), thermoplastic polyurethane (TPU), silicone, polyethylene terephthalate (PET), aluminum, nylon, polyethylene (PE), plasticized polyvinyl chloride (PVC), natural fibers, or combinations thereof. In some embodiments, the elongated body 902 may have a generally rectangular, band-like configuration. In other embodiments, the elongated body 902 may be a wire, rope, filament, etc. It is conceivable that the elongated body 902 may take the form of one or more S-shaped hooks, which are configured to have a first end that engages with the connector portion 265 and a second portion that is configured to receive a handle or suspension mechanism of the reservoir 302.

[0120] The elongated body 902 may further include a first aperture 908 and a second aperture 910, the first aperture extending through the thickness of the elongated body 902 and adjacent to a first end 904, and the second aperture extending through the thickness of the elongated body 902 and adjacent to a second end 904. In some embodiments, the first aperture 908 and / or the second aperture 910 may be reinforced with a sling or other reinforcing rings 912, 914. The reinforcing rings 912, 914 can help prevent tearing or ripping in the elongated body when the reservoir 302 is suspended on the elongated body 902. The apertures 908, 910 may be configured to receive fastening members passing through them. The fastening members may be similar in form and function to those described above. Figure 10 The fastening member 814 is described. The fastening member can be a hook, buckle, safety hook, S-hook, ring, etc. For example, the fastening member can have a first portion and a second portion, the first portion being configured to extend through a first orifice 908 and a second orifice 910, and the second portion being configured to receive a handle 316 or suspension mechanism of the reservoir 302. In some examples, the first portion and the second portion can be different areas of the same ring. However, this is not necessary. It is further conceivable that orifices 908 and 910 can be omitted, and the elongated body 902 can be fastened or otherwise directly secured to the handle 316 of the reservoir 302.

[0121] To suspend the reservoir 302 on the connecting member 900, the connecting member 900 can be positioned above the connector portion 265 of the umbilical cord 260. It is conceivable that the connecting member 900 can be suspended at multiple different locations on the connector portion 265. Figure 11 In this configuration, the connecting member 900 may be positioned on the front side (e.g., in an area extending substantially orthogonally to the processor 210). However, this is not necessary. Figure 12 A perspective view shows an illustrative connecting member 900 positioned above the lateral end or "ear" of connector portion 265. The lateral end may extend in a direction substantially parallel to processor 210. Furthermore, Figure 12 Two connecting members 900 are shown positioned above connector portion 265 at its opposite lateral ends. It is conceivable that one, two, three, four, or more connecting members 900 can be used to secure reservoir 302 relative to connector portion 265. It is also conceivable that if two or more connecting members 900 are used, two or more securing members can also be used. For example, a separate securing member can be used for each connecting member 900. However, this is not necessary. In some cases, one securing member can be used for two or more connecting members 900. Once the connecting members 900 are positioned above umbilical conduit 260, the securing member can be connected to orifices 908, 910. The handle 316 or suspension mechanism of reservoir 302 can then be suspended from the securing member.

[0122] As will be understood, the lengths of the irrigation tubing, lens cleaning tubing, gas supply tubing, and alternative gas supply tubing can have any suitable dimensions (e.g., diameter). Additionally, the tubing dimensions (e.g., diameter) can vary depending on the application. In one non-limiting embodiment, the irrigation supply tubing can have an inner diameter of approximately 6.5 mm and an outer diameter of 9.7 mm. The lens cleaning supply tubing can have an inner diameter of approximately 5 mm and an outer diameter of 8 mm. The gas supply tubing can have an inner diameter of approximately 2 mm and an outer diameter of 3.5 mm. The alternative gas supply tubing can have an inner diameter of approximately 5 mm and an outer diameter of 8 mm.
