[0001] This disclosure relates to a cleaning device system for surgical instruments. More specifically, this disclosure relates to a novel and advantageous cleaning device system for a laparoscopy. The cleaning device system includes a cleaning device, a module, and a control panel. The cleaning device includes a shaft and nozzles for guiding flushing and drying fluids toward the ends of the surgical instruments. The module may be a self-contained unit housing saline solution for cleaning, CO2 for drying, and a battery for powering the system.

[0002] The background description provided herein is intended to present the overall context of this disclosure. The extent to which the work of the inventors currently presented is described in this background section, and aspects of the description that may not have qualified as prior art at the time of filing, are neither explicitly nor implicitly considered to be prior art to this disclosure.

[0003] Laparoscopy offers a low-risk and minimally invasive method for visual guidance during surgery. During surgery, the laparoscopic lens is often obscured by various bodily fluids such as fat and blood, as well as fog. Currently, the common procedure for cleaning the lens requires removal from the body, leading to surgical delays and increasing the risk of infection. The average lens cleaning frequency during surgery is approximately six cleaning events per hour.

[0004] Therefore, there is a need in the art for a device for cleaning laparoscopic lenses and other intraoperative lenses without removing them from the body. Summary of the Invention

[0005] The following presents a brief overview of one or more embodiments of this disclosure to provide a basic understanding of such embodiments. This invention is not a comprehensive summary of all contemplated embodiments and is neither intended to identify key or essential elements of all embodiments, nor to limit the scope of any or all embodiments.

[0006] This disclosure relates to a cleaning device for surgical instruments. More specifically, this disclosure relates to a novel and advantageous self-contained cleaning device system for cleaning lenses of surgical instruments, such as laparoscopic instruments, inside the body. The cleaning device system can be used to retrofit existing surgical instruments or can be incorporated into new surgical instruments.

[0007] A cleaning device system can be provided as a laparoscopic accessory that can be used during surgical procedures, such as in the abdomen. The system can be self-contained, requiring no wiring or connection to operating room resources. More specifically, the cleaning device system can be a self-contained, battery-powered, self-cleaning retrofit kit containing built-in heating, flushing, and jet drying or aspiration systems. The system allows for lens cleaning without removing the laparoscopic lens from the body, thus reducing surgical time and workflow. In some embodiments, the cleaning device is fitted onto the laparoscope and provides fluid flow across the laparoscopic lens.

[0008] In one or more embodiments, this disclosure further relates to a cleaning device system for cleaning lenses for use with a surgical apparatus having a shaft and a lens at the distal end of the shaft. The cleaning device system may be a self-contained, battery-powered, self-cleaning retrofit kit including a built-in heating, rinsing, and drying system.

A sheath is configured for mounting on the shaft of the surgical apparatus and has a flushing channel and a drying channel. The nozzle is coupled to the distal end of the sheath. The nozzle has a flushing port and a drying port, the flushing channel terminating at the flushing port and the drying channel terminating at the drying port. The module houses a flushing fluid reservoir, a gas reservoir, and a power source. A first fluid is dispensed from the flushing fluid reservoir in the module through the flushing channel in the sheath and flushed from the flushing port in the nozzle. A second fluid is dispensed from the gas reservoir in the module through the drying channel in the shaft and ejected from the drying port in the nozzle. In some embodiments, the non-tactile mechanism may be autonomous. Such an autonomous mechanism may include a sensor that senses when the lens becomes dirty by evaluating an image from the lens or a sensor that senses when the lens becomes dirty by evaluating light reflection. In another embodiment, the non-tactile mechanism is voice-activated. In some embodiments, the non-tactile mechanism may activate a drying cycle. It can also provide another tactile or non-tactile mechanism to activate a supplemental cleaning or drying cycle.

[0010] In yet another embodiment, a cleaning device system for use with a surgical apparatus having a shaft and a lens at the distal end of the shaft is provided. The cleaning device system includes a cleaning device, a module, and a control board. The control board may be provided as part of the cleaning device, or may be separate from and operatively connected to the cleaning device. The cleaning device may include a sheath and a nozzle. The sheath may be fitted onto the shaft of the surgical apparatus. The sheath may have a flushing channel, a drying channel, and a heating channel, wherein the heating channel is positioned adjacent to the flushing channel. The nozzle may be coupled to the distal end of the sheath. The nozzle may have a flushing port and a drying port, the flushing channel terminating at the flushing port and the drying channel terminating at the drying port. The module may house a flushing fluid reservoir, a CO2 tank, and a power source. The flushing fluid reservoir may have a capacity sufficient to perform at least ten flushes without refilling. Physiological saline is dispensed from the flushing fluid reservoir in the module through the flushing channel in the sheath and flushed from the flushing port in the nozzle, and CO2 gas is dispensed from a gas reservoir in the module through the drying channel in the shaft and ejected from the drying port in the nozzle. The saline solution is heated to a temperature of at least 104℉ in the rinsing channel. The control panel may have a first button and a second button, wherein the first button activates a cleaning cycle that includes dispensing saline solution and dispensing CO2, and the second button activates a supplemental drying cycle that includes dispensing CO2.

[0090] This disclosure relates to a cleaning device system for surgical instruments. More specifically, this disclosure relates to a novel and advantageous cleaning device system for a laparoscopy. The cleaning device system includes a cleaning device, a module, and a control panel. The cleaning device includes a shaft and nozzles for guiding flushing and drying fluids toward the end of the surgical instrument. The module may be a self-contained unit housing saline solution for cleaning, CO2 for drying, and a battery for powering the system. The cleaning device may be a retrofit device for an existing laparoscope or may be incorporated into a new laparoscope or similar device. For example, in some embodiments, the laparoscope or other endoscope of the present invention may incorporate one or more of the design elements of the invention in a manner that eliminates the need for additional accessories to utilize the functionality described herein.

[0091] Cleaning device systems are available as laparoscopic attachments that can be used during surgical procedures, such as in the abdomen. The system can be self-contained, requiring no wiring or connection to operating room resources. More specifically, the cleaning device system can be a self-contained, battery-powered, self-cleaning retrofit kit containing built-in heating, flushing, and jet drying or aspiration systems. The system allows lens cleaning without requiring removal of the laparoscopic lens from the body, thus reducing surgical time and workflow. In some embodiments, the cleaning device is fitted onto the laparoscope and provides fluid flow across the laparoscopic lens. A smaller volume of fluid remains in the body to ensure postoperative absorption.

[0092] Generally, cleaning devices can be used with any surgical instrument used inside the body and include a shaft with an end that needs cleaning. Cleaning device systems can be used to remove substances such as fat, blood, and mist from the lenses of surgical instruments, such as laparoscopy, while the surgical instrument is inside the body.

[0093] In one embodiment, a cleaning device is fitted onto a laparoscope and operates by providing a controlled flow of a first fluid (e.g., water or saline) across the lens, followed by the injection of CO2 or other fluids to aid in the removal of loose debris and the first fluid, and to dry the lens. The first fluid, such as water or saline, the second fluid, such as CO2, and the power source, such as a battery, can be integrated into the cleaning device system, eliminating the need for connection to operating room resources. This minimizes the volume of fluid remaining in the body after cleaning, promoting postoperative absorption.

[0094] It should be understood that the cleaning device can alternatively be designed to attach to a surgical robot or other device by customizing the size of its sheath, and to operate in a substantially the same manner as described herein with respect to laparoscopy, to clean such lenses of any in-body device. The cleaning device can be configured to facilitate articulation, allowing it to be used with articulated surgical devices. Furthermore, the cleaning device can be configured to be flexible (e.g., with a flexible sheath) for use with endoscopic-type systems.

[0095] In some embodiments, the system can be configured for abdominal pneumoperitoneum. This involves pumping a gas, such as CO2, into the peritoneal cavity to create pneumoperitoneum and cause an increase in intra-abdominal pressure (IAP). To perform such pneumoperitoneum, a cleaning device can be activated to dispense only CO2 without flushing. For pneumoperitoneum, the sheath has a drying tube sized for an appropriate CO2 flow and a nozzle configured to direct CO2 outward from the device. Carbon dioxide can be injected into the peritoneal cavity at a rate of 4 to 6 liters per minute to achieve a pressure of 10 to 20 mm Hg.

[0096] Figures 1a and 1b illustrate embodiments of a cleaning device system. Figure 1a shows a cleaning device system 10, with its cleaning device 12 mounted to a laparoscope 5. Figure 1b shows a cleaning device system not associated with a surgical apparatus. As shown, the cleaning device system 10 may include a cleaning device 12 and a module or control box 18. The cleaning device 12 includes a sheath (also referred to as a shaft) 14, a nozzle 15, a control plate 16, and a retaining feature 20. In the embodiments shown in Figures 1a and 1b, the module 18 carries a reservoir for containing fluids for cleaning the lens and receives a CO2 canister or cylinder for drying the lens. While CO2 canisters are discussed herein, any suitable material or method may be used for jet drying in such embodiments. The module 18 may further include a battery for powering the cleaning device system. As shown in Figure 1b, a conduit 17 may extend between the cleaning device 12 and the module 18 to feed a first fluid and a second fluid, such as saline and CO2, from the module 18 to the cleaning device 12. A cable 19 extends from the module 18 to the control plate 16 to power the control plate 16. Shipping containers (shown in Figures 5a and 5b) can also be provided.

[0097] As shown in Figure 1a, the cleaning device 12 can be mounted onto an existing laparoscope such that, when positioned, the laparoscope's lenses are exposed, and the user can operate the laparoscope for normal use and actuate buttons on the control panel of the cleaning device to clean the laparoscope's lenses. The control panel can be used to remove debris from the lenses using a first fluid, such as saline or water, and to blow a second fluid, such as CO2, onto the entire lens to further remove debris and dry the lens. This disclosure specifically discusses cleaning devices for use with laparoscopes such as 10mm 30-degree laparoscopes. Such specificity is for illustrative purposes only and is not intended to be limiting. With a specific reference laparoscope, the cleaning device can be used with virtually any size sheath, such as sheaths with diameters of 3mm, 5mm, 8mm, and 10mm and angles of 0 degrees, 10 degrees, 30 degrees, and 45 degrees. It should be understood that the length and diameter of the sheath can be customized for the surgical device or surgical robot to be used with it.

[0098] A cleaning device system can be used to flush and dry lenses at the end of surgical instruments, such as laparoscopes or surgical robots. In various embodiments, drying can be accomplished by jet drying or by suction. In some embodiments, cleaning can be a closed loop. The cleaning device system can be a self-contained system that carries its own flushing fluid, drying mechanism, and battery, eliminating the need for operating room water, air, and electricity. In other embodiments, the cleaning device system can be connected to operating room water, air, and / or electricity. Furthermore, when provided as a self-contained system, the cleaning device system may still have backup connections to operating room water, air, and / or electricity.

[0099] In some embodiments, all or part of the cleaning device system may be disposable. For example, in one embodiment, the sheath and control panel / grip are each disposable, while the control panel and modules may be reusable. In another embodiment, only the sheath is disposable, while other components are reusable. In embodiments utilizing a CO2 canister, the canister may be disposable. Similarly, the reservoir may be fully replaceable or reusable. Generally, it is useful for at least the heater element and electronics to be reusable. In alternative embodiments, the cleaning device system may be entirely disposable.

[0100] Figures 2a, 2b, and 2c illustrate various embodiments of a cleaning device, including a sheath 14 and a nozzle 15, mounted on a laparoscope 5 according to other embodiments. The sheath may have a retaining feature 20 for securing the sheath 14 to the surgical device. Figure 2b further illustrates a shaft tube receiver 21 for receiving tubing from the module. In the embodiment of Figure 2c, the sheath 14 is C-shaped and has an open channel 24 along its upper surface.

[0101] Figure 2c further illustrates one embodiment of nozzle 15. The nozzle is located at the distal end of the sheath and can be connected to the tip of the sheath. The nozzle can be configured to direct flushing fluid and CO2 (or other fluids or suction) toward the lens.

[0102] Figure 3a shows the sheath 14 of the cleaning device connected to the control panel 16. Figures 3b and 3c show the control panel 16 according to various embodiments. The control panel may include a connection interface for connecting to the laparoscope at the distal end of the lamp port of the laparoscope. As shown, the control panel includes interface controls, namely a first button 30 and a second button 32. The buttons may be, for example, located on a two-button membrane switch. The first button 30 may be referred to as the flushing button, and the second button 32 may be referred to as the drying button. The flushing button 30 actuates the flushing valve, and the drying button 32 actuates the drying valve. In some embodiments, the first button 30 may actuate both the flushing valve and the drying valve, thereby initiating a cleaning cycle, and the drying button 32 may have a supplementary drying function. In such embodiments, the flushing button may be referred to as a cycle button that activates both the flushing and drying functions. If the lens is not sufficiently dried after actuating the cycle button 30, the drying button 32 may be actuated to trigger further drying.

[0103] The control board is communicatively connected to the module, enabling the activation of buttons on the control board to actuate valves within the module. For example, a cable can be installed between the control board and the module. Alternatively, communication can be achieved via infrared, radio frequency, Bluetooth, or other methods.

[0104] The valves in the module can be mechanical or electric. Buttons 30 and 32 can actuate momentary switches, allowing the user to control the rinsing and / or drying time. Alternatively, buttons 30 and 32 can actuate electric switches for preset running times. In one embodiment, the valves are electronically controlled, including buttons on a control panel and solenoid valves in the module. In an alternative embodiment, interface controls can be provided on the module, and a control panel may not be required on the cleaning device.

[0105] While specific details are given regarding one or more buttons for controlling rinsing and drying, this function can also be triggered in other ways. For example, the cleaning device system may have voice activation for controlling rinsing and drying. In another embodiment, cleaning may be automatic. More precisely, the cleaning device may detect when the lens of the surgical apparatus becomes dirty and may run one or more cleaning cycles automatically. This detection may be performed, for example, by using a light sensor and detecting the refraction of light passing through the lens. In some embodiments, software analysis of white light spectral analysis and light reflection may be used to detect whether the lens is dirty. In another automatic embodiment, the cleaning device may detect lens dirt by viewing an image generated by a camera and detecting image blur. In some embodiments, the cleaning device system may have the ability to automatically run cycles and also have supplementary cleaning cycles or drying functions via a control panel.

[0106] Figures 4a and 4b illustrate a module / control box 18 according to one embodiment. Module 18 encapsulates multiple components of the cleaning device system. Generally, the module is protective and has a small size. The module houses a flushing fluid reservoir and a CO2 canister or cylinder. Each of the fluid reservoir and CO2 canister may be replaceable and / or refillable, including replacement and / or refillability during the surgical procedure. The module may additionally house a battery. Alternatively, the module may be configured to connect to operating room power. CO2 may be used to drive the pumping of flushing fluid and provide air evacuation or vacuum for each cleaning event. The fluid reservoir may be provided as a cylinder with flushing and waste storage capabilities and may be disposable. The CO2 canister, fluid reservoir cylinder, and battery may all be replaceable during the surgical procedure, as needed. That is, the fluid reservoir and / or CO2 canister may have sufficient capacity so that it is not necessary to refill the fluid reservoir or replace the CO2 canister during the surgical procedure. In alternative embodiments, one or more of the fluid reservoir, CO2 canister, or battery may not be housed in the module.

[0107] In one embodiment, the fluid reservoir is refillable and retains sufficient capacity to run, for example, 8 to 20 cleaning cycles before refilling is required. In another embodiment, the fluid reservoir retains sufficient capacity to run 10 cleaning cycles before refilling is required. In one embodiment, the amount of fluid used per cleaning cycle is 1.25 ml, and the fluid reservoir holds a minimum of 30 ml of fluid, plus an additional capacity (10 ml) to accommodate system purification and tolerances. The capacity of the fluid reservoir can be customized based on the intended use of the cleaning device system. In one embodiment, a 16g compressed CO2 cartridge is provided.

[0108] In one embodiment, the module may be sized to accommodate a fluid reservoir, CO2 canister, and battery capable of cleaning 5 to 20 times, wherein the cleaning has a flush volume in the range of about 0.25 mL to about 0.5 mL (e.g., 1.25 mL or 1.5 mL) and a flush time in the range of about 1 second to about 3 seconds. For example, in one embodiment, the module may be sized to accommodate a fluid reservoir, CO2 canister, and battery capable of cleaning 10 times, each flush lasting about 3 seconds. The fluid reservoir may be between about 10 mL and about 30 mL in size. In one embodiment, the amount of fluid used per cleaning is 1.25 ml, and the fluid is dispensed at a minimum rate of 6 times per hour. The battery may have any suitable capacity. In one embodiment, the battery may have a 9.18 watt-hour capacity.

[0109] Figure 4a shows module 18, which has a CO2 tank 40 received by CO2 port 41, a pressure gauge 42, a filling port 44, a saline port 46, a CO2 port 48, and an electrical connection port 50. Saline port 46 and CO2 port 48 receive fittings 47 and 49, respectively. Fittings 47 and 49 receive tubing for connection to a cleaning device. In an alternative embodiment, ports 46 and 48 may be directly connected to tubing. Electrical connection port 50 receives cable 51.

[0110] Figure 4b shows module 18, which has a ready button 53, a heat adjustment knob 54, a planning access 55 (insertion), a power switch 56, a power access 57, and a pressure adjustment knob 58.

[0111] Module 18 may further accommodate an electronic controller, a momentary switch for performing system purification, a power switch for supplying power to the system, and a regulator. The momentary switch for performing system purification may be incorporated into a power-on sequence, which involves inserting the device, pressing the power switch, supplying power to the system, and then distributing a certain volume of fluid through the system.

[0112] Figures 5a and 5b illustrate a transport case 60 for storing a cleaning device system and optional accessories. More specifically, the transport case may be used to house the device (including shafts and tubing assemblies), module / control box, filling syringe and tubing assemblies, and USB Type A to USB Type Micro B cables (or other charging cables or mechanisms). The transport case 60 may have two layers; the top layer is shown in Figure 5a, and the bottom layer is shown in Figure 5b. In one embodiment, the layers are formed by foam trays. The exact configuration is for illustrative purposes only, and the transport case may house the cleaning device system in alternative configurations.

[0113] In the embodiment of Figure 5a, the top tray 62 of the transport container 60 houses the module or control box 18, the filling syringe and tubing assembly 64, and the microfiber towel and strapping 66. Storage locations 68 for multiple CO2 canisters are provided, with the canisters placed on the lower tray.

[0114] In the embodiment shown in Figure 5b, the bottom tray 70 stores the cleaning device 12, multiple CO2 canisters 72, a power supply and power cord 74, and a USB Type A to USB Type Micro B cable 76. The multiple CO2 canisters may be, for example, four 16g CO2 canisters.

[0115] In various embodiments, during surgery, the module may be mounted on the surgical tool shaft, on the cleaning device control panel, or separate from the cleaning device. Figures 6a to 6c show the module 18 in different locations.

[0116] Figure 6a shows module 18, which is provided separately from surgical instruments 5 and cleaning device 12 so that it can be positioned on the operating table.

[0117] Figure 6b shows module 18 mounted on the shaft of surgical tool 5. This embodiment can be applied, for example, to a laparoscopy or other surgical device specifically designed for the treatment of obesity with a relatively long shaft.

[0118] Figure 6c shows module 18, which is provided separately from surgical tool 5 and cleaning device 12 and configured to be worn on the user's wrist.

[0119] Returning to Figure 1a, a cleaning device system with a laparoscope is shown. The cleaning device 12 is attached to the laparoscope and includes a sheath 14, a nozzle 15, and a control plate 16. In some embodiments, the shaft includes a hollow tube structure with two channels or lumens, one channel or lumen for a first fluid such as physiological saline, and the other channel or lumen for a second fluid such as compressed CO2. These channels may be referred to as a flushing channel and a drying channel. The size of the shaft structure can be set to the size of the endoscope or other surgical instruments. It should be understood that this size adjustment will vary depending on the surgical apparatus used with the cleaning device. In one embodiment, the shaft may have a mounting configuration for a Karl Storz endoscope P / N 26003BA (…). The tube structure has a 30° tip and a length of 31 mm, and can be used to traverse the ID of the Ethicon XCEL bladeless cannula with a stable sleeve of 12 mm to 100 mm.

[0120] The shaft of the cleaning device can be formed from any suitable material. For example, the shaft can be formed from extruded plastic or welded stainless steel. The sheath 14 includes a proximal end that interfaces with the control plate 16 and a distal end that interfaces with the nozzle 15. The sheath 14 may have a retaining feature 20 for confining the shaft of the sheath to the surgical device. The sheath may include an irrigation channel and a drying channel. The sheath may further include a heating element channel. In some embodiments, more than one irrigation channel, drying channel, or heating element channel may be provided. The size of the sheath 14 can be configured to accommodate a laparoscopic shaft or a shaft of other surgical devices. Thus, for example, if the cleaning device will be used with a 10mm laparoscopic shaft, the sheath may have an inner diameter of about 10mm and an outer diameter of about 12mm. If the cleaning device will be used with a 5mm laparoscopic sheath, the sheath may have an inner diameter of about 5mm and an outer diameter of about 7mm. Therefore, the thickness of the shaft may be about 2mm. In alternative embodiments, different inner and outer diameters and different thicknesses may be used. Whether by manufacturing a lubricating material or by adding a lubricating coating, the shaft can have a lubricated interior to facilitate the sliding of the sheath 14 onto the shaft of a surgical instrument, such as a laparoscopic tool.

[0121] In some cases, it may be necessary to heat the flushing fluid to facilitate the removal of grease and mist. For example, it may be necessary to heat the fluid to a temperature of at least about 40°C (104°F). Therefore, a heating element can be provided to heat the fluid to about 40°C (104°F). This heating can be performed by heating the fluid in the shaft or at the reservoir. The heating element can be selected such that it can heat the fluid to the desired temperature, such as 40°C, in 10 minutes or less. In various embodiments, the heating element may be a conformal shaft resistance heater. In one embodiment, the heating element includes a resistance heating wire inserted into a resistive wire conduit. Heating can be achieved using open or closed loop methods (with or without temperature sensing). The heating element may be disposed in a heating element channel in the shaft and powered by a battery in the module. Alternatively, other heating elements or methods may be used. For example, in another embodiment, the lens area may be heated instead of the fluid. In this embodiment, a heated lens may be positioned above a laparoscopic lens (ITO coating / film).

[0122] The sheath and nozzle of the cleaning device are complementary, such that a channel in the sheath engages with a port in the nozzle. In one embodiment, the rinsing channel and the drying channel are opposite each other on opposite sides of the sheath. In another embodiment, the rinsing channel and the drying channel are on the same side of the sheath. In one such embodiment, the rinsing direction is downward and to the right (facing distally), and the drying direction is downward and to the left (facing distally). The cross-sectional areas of the rinsing channel and the drying channel may be the same or different. In embodiments using a rinsing channel and a suction channel (relative to the drying channel), the rinsing channel may have a greater lateral suction than the vacuum channel to provide higher speeds.

[0123] Figures 7a, 7b, and 7c show a sleeve 14 of a cleaning device according to an exemplary embodiment, wherein the rinsing channel and the drying channel are on the same side of the sleeve. Figure 7a shows a perspective view of the sleeve 14 of a cleaning device according to one embodiment. As shown, the sleeve has a thicker upper wall that gradually narrows along the wall towards the open bottom.

[0124] Figures 7b and 7c show end views of the sheath 14 shown in Figure 5a according to two embodiments. The end views show a flushing channel or cavity 80 and a drying channel or cavity 82 in the upper wall of the sheath 14. A heating channel 84 is provided between the flushing channel 80 and the drying channel 82. The heating channel 84 can receive a resistive wire.

[0125] Figures 8a and 8b show variations of the embodiments illustrated in Figures 7a to 7c. In the embodiments of Figures 8a and 8b, the rinsing channel 80 and the drying channel 82 are on the same side of the sheath 14. The thicker upper wall of the sheath 14 gradually narrows towards the thinner bottom wall.

[0126] The nozzle of the cleaning device may have any suitable configuration for guiding the flushing fluid and, optionally, a drying fluid such as CO2, generally toward the lens. In some embodiments, the flushing fluid and the drying fluid may be guided toward the lens in the same manner. In other embodiments, the flushing fluid and the drying fluid may be guided in different manners, for example, wherein the flushing fluid is guided at the lens while the drying fluid is guided across the lens.

[0127] Figures 9a to 9d illustrate the nozzle of a cleaning device according to one embodiment. Figure 9a shows the end of a laparoscope, wherein a sheath 14 of the cleaning device is disposed around the shaft of the laparoscope 5, but the nozzle is not attached to the sheath 14. Figure 9a shows the laparoscope 5 at 30 degrees. As shown, the sheath 14 of the cleaning device may terminate before the end of the laparoscope. In an alternative embodiment, the sheath 14 of the cleaning device may extend to or beyond the end of the laparoscope.

[0128] Figure 9b shows a nozzle 15 for attachment to a shaft of a cleaning device according to one embodiment. Figures 9c and 9d show the nozzle of Figure 9b attached to a sheath 14 of the cleaning device positioned on the shaft of a laparoscope 5 according to one embodiment. In the illustrated embodiment, the nozzle 14 is folded above the upper wall of the laparoscope sheath to direct flushing fluid and air or CO2 toward the lens of the laparoscope for drying.

[0129] Details of setting up a cleaning device system will now be given according to one embodiment.

[0130] Figures 10a and 10b illustrate the initial optional steps after removing the system from the transport container. In some embodiments, the shaft support element 100 may be disposed in the sheath 14 during storage. The initial step is therefore to remove this shaft support element 100 (if provided).

[0131] Figures 11a and 11b show the insertion of the laparoscopic shaft into the sheath 14 of the cleaning device and the laparoscopic shaft being secured in the sheath 14. Figures Ba and Bb show the laparoscope P / N 26003BA ( A cleaning device with a 30° tip and a length of 31 mm. However, the cleaning device can be used with any suitable surgical instrument or robot, and the scope is shown for illustrative purposes only.

[0132] Figure 11a shows the endoscope inserted into the sheath 14. Insertion is achieved by retaining feature 20. The endoscope is inserted such that the lamp post 7 on the laparoscope is adjacent to or nearly adjacent to retaining feature 20. The shaft tube receiver 21 can be attached to the lamp post 7 using any suitable mechanism. For example, the shaft tube receiver 21 can be attached to the lamp post 7 using a cable tie, as shown in Figure 11b.

[0133] Therefore, for use with the cleaning device, the sheath 14 is attached to the retaining feature 20 (optionally housing the control plate 16), and the retaining feature is attached to the laparoscope at the lamp post 7 of the laparoscope. Figure 11c shows this connection.

[0134] The cleaning device may include a tubing assembly and control cables. In one embodiment, the tubing assembly and cables are permanently attached to a shaft and detachably connected to a module / control box. In alternative embodiments, any one or both of these embodiments may be detachably connected to a shaft or permanently attached to a module / control box. In one embodiment, the length of the tubing assembly and cables is approximately 1000 mm - 0 / +50 mm.

[0135] Figures 12a to 12c illustrate embodiments where fittings 47 and 49 are connected to ports 46 and 48 and cable 51 is connected to electrical port 50, wherein the tubing assembly is detachably connected to the module. Fittings 47 and 49 and ports 46 and 48 may be color-coded to ensure that the correct fitting 47 or 49 is connected to the correct port 46 or 48. More specifically, fittings 47 and 49 and ports 46 and 48 may be color-coded to ensure that saline fitting 47 is connected to saline port 46 and CO2 (or other fluid) fitting 49 is connected to CO2 (or other fluid) port 48.

[0136] Figure 12a shows module 18 before connectors 47 and 49 are connected to ports 46 and 48, but after cable 51 is connected to electrical port 50. Figure 12b shows the reverse connection sequence, where connectors 47 and 49 are first connected to ports 46 and 48, and then cable 51 is connected to electrical port 50. Figure 12c shows module 18 with connectors 47 and 49 connected to ports 46 and 48 and cable 51 connected to electrical port 50. In one embodiment, connecting the cable includes aligning a connector of cable 51 with electrical port 50, pushing the connector into port 50 for connection, and rotating the connector to lock it in place.

[0137] The internal reservoir of the module is filled using a filling syringe and tubing assembly (62 of FIG. 5a). Filling can be performed, for example, by inserting the tubing into the push-connect filling port 44. In one embodiment, for filling the reservoir, the power switch must be in the off position to allow air behind the piston cylinder to escape during the filling process. Figure 13 The diagram shows the filling syringe tube 63 being removed from the filling port 44, along with the filling syringe and tubing assembly 62. In one embodiment, this removal can be performed by pressing inwards on the loop tube 45 surrounding the filling syringe tube and pulling the tube away from the port 44.

[0138] Figures 14a and 14b show the pressure after filling the reservoir. Check the pressure gauge or regulator 42 to ensure the pressure is set to zero pounds per square inch (psi). The pressure adjustment knob 58 can be used to adjust the pressure as needed.

[0139] Figures 15a and 15b illustrate the installation of a CO2 canister or cylinder 40 according to one embodiment. The CO2 cylinder 40 may be, for example, a 16g CO2 cylinder. The CO2 cylinder 40 is screwed onto the CO2 port 41 on module 18. The screwing force decreases as the closed end of the CO2 cylinder 40 is penetrated. Tightening should continue until the connection is tightened by hand. Alternatively, the connection from the CO2 cylinder 40 to the port 41 may be made without screwing and may be made by other suitable mechanisms, such as a press-fit.

[0140] After installing the CO2 cartridge, the pressure can be adjusted to the desired pressure using the pressure adjustment knob 58, typically within the range of 0 psi to 80 psi. For example, the pressure can be adjusted to 40 psi. The power supply can be plugged into the module and connected to electricity, and the power switch can be turned on. When power is on, an indicator light will be activated to show that power is on. The heat adjustment knob (54 in Figure 4b) can be used to adjust the power to the heating element as needed. Press the ready button (53 in Figure 4b) until a small amount of saline solution is dispensed from the nozzle. At this point, the device is ready for use.

[0141] Details of the use of the cleaning device system will now be given according to one embodiment. In use, the camera, laparoscope, and light source operate normally. Light from the laparoscope continues to act through the clear tip of the shaft. A default mode can be set for pulsed CO2.

[0142] A control panel can be used to activate cleaning. Buttons on the control panel control the use of the cleaning device. As described with respect to Figure 3a, these buttons may include, for example, a cycle button 30 that activates both rinsing and drying, and a drying button 32 that activates only drying. A single press of the cleaning cycle button causes a brief spray of saline solution, followed by CO2 spraying at the nozzle. The drying button is programmable to operate in one of two modes: pulsed and continuous. In pulsed mode, a single press of the CO2 button causes the release of CO2 in a programmed number of CO2 sprays. In continuous mode, pressing the CO2 button directly controls the duration of CO2 dispensing. To conserve CO2 and prevent the CO2 cylinder from freezing, the continuous dispensing mode can be programmed with a limit on the dispensing duration while the CO2 button is held down. After a cleaning cycle, a short period of time without cleaning may be required for reheating the fluid in the shaft. If the CO2 is depleted during the procedure, it can be replaced by removing the cylinder from its position on the module and replacing the cylinder. Similarly, if the reservoir is empty during the procedure, it can be refilled using a filling syringe.

[0143] The cleaning device can be programmed to customize the cycle and CO2 parameters. Specifically, the variables controlling the cleaning cycle and CO2 cycle can be modified to achieve different system functions, such as shorter eruption times and longer lockout delays.

[0144] Clean cycle variables may include saline dispensing time (e.g., 100 ms), the delay between dispensing saline and CO2 variables (e.g., 500 ms), and CO2 dispensing time variables (e.g., 800 ms).

[0145] CO2 variables can be based on whether the system is operating in continuous CO2 mode or pulsed CO2 mode. Variables in continuous CO2 mode may include CO2 run time variables (e.g., 500 milliseconds) and system recovery time variables (e.g., 2000 milliseconds). Variables in pulsed CO2 mode may include pulse number variables (e.g., 8 pulses) and pulse duration variables (e.g., 25 milliseconds).

[0146] Various exemplary configurations of the components of the cleaning device system are shown in Figures 16a to 20g.

[0147] Figures 16a to 16d show the extruded plastic sheath 14 and the distal end of the nozzle 15 of the cleaning apparatus according to one embodiment. In this embodiment, the rinsing channel or cavity 80 and the drying channel or cavity 82 are arranged opposite each other. As shown, the rinsing channel 80 may include two rinsing channels 80. One or a heating channel 84 may be arranged close to the rinsing channel 80. In an embodiment with two rinsing channels 80, the heating channel 84 may be arranged between the two rinsing channels 80. The heating channel 84 may receive a resistive wire.

[0148] Figures 16a and 16b show an extruded plastic sheath 14 with an injection-molded tip, wherein a nozzle 15 is attached to a shaft tip. Figure 16c shows an end view of the injection-molded tip. In the illustrated embodiment, two flushing channels 80 and a heating element channel 84 are provided on a first side of the sheath 14, and a drying channel 82 or CO2 channel is provided on a second side of the sheath 14 opposite to the first side. A tip key notch 85 is provided in the sheath 14. Figure 16d shows a rear view of the nozzle 15 of the cleaning device according to an embodiment. As shown, the nozzle 15 includes a tip key 85 for engaging the tip key notch of the sheath 14. While the tip key and tip key notch are one way to attach the nozzle 15 to the sheath 14, it should be understood that any suitable mechanism for attaching the nozzle 15 to the sheath 14 can be used. For example, the nozzle 15 may be press-fitted or screwed onto the sheath 14.

[0149] Figures 17a and 17d show the distal ends of a welded stainless steel sheath 14 and a nozzle 15 of a cleaning apparatus according to one embodiment, wherein a heating element 90 layers are connected to the sheath 14. Figure 17a shows a perspective view. Figure 17b shows a cross-sectional view. Figure 17c shows a cross-sectional view of the sheath 14 only. Figure 17d shows a perspective view of the nozzle 15 only. The shaft may be formed by laser cutting, forming, and / or welding of the assembly. The tip may be a machined metal tip.

[0150] As shown in Figure 17c, the shaft may have an outer wall 92 and an inner wall 94, wherein the heating element 90 is disposed between the outer wall 92 and the inner wall 94 on one side of the sheath 14. The outer wall 92 and the inner wall 94 may be welded together at a weld point shown, for example, at 96.

[0151] Figures 18a to 18f illustrate various aspects of a cleaning device 12 for use with a laparoscopy 5 according to one embodiment. In the embodiment shown in Figures 18a to 18f, the retaining feature 20 is integrated with the control panel 16. For example, a shaft tube receiver 21 is shown and may include a flushing tube receiver 21a and a jet drying tube receiver 21b. A stress relief element 102 may be provided at the cable / pipe outlet. A membrane switch 100 may be provided on the control panel retaining features 16 / 20. A heating element port 104 and a heating element channel 106 may be provided for receiving heating elements.

[0152] Attachment can be made by connecting the injection molding control plate retaining feature 16 / 20 to the extrusion sheath 14 via an overlap joint or extrusion 108. An adhesive plug 110 can be used to seal the open end of the extrusion. The plug 110 provides stress relief for the heating element, such as the heating element wire. In this embodiment, a two-button membrane switch 100 is provided to control the rinsing and spray drying functions. A single stress-relieving element 102 combines the rinsing tube, the spray drying tube, and the cable (switch and heating element conductor). While this embodiment is specifically discussed in relation to spray drying, it should be understood that it can also be used with vacuum drying.

[0153] Figures 19a to 19c show overlapping extrusion embodiments similar to those in Figures 18a to 18f, but in which the rinsing channel 80 and the drying channel 82 are on the same side of the sheath 14, there is no lip on the bottom edge of the nozzle, and the overlapping joint 112 is at the connection between the nozzle 15 and the sheath 14.

[0154] Figures 20a to 20d illustrate the attachment of the sheath according to yet another embodiment. In the illustrated embodiment, attachment is performed using a connection by providing an injection-molded assembly in the control panel 16 and attaching such an assembly to the shaft using an expansion extruder 114. In this embodiment, a dual-button membrane switch is provided to control the rinsing and jet drying functions. A single stress relief unit combines the rinsing tube, the jet drying tube, and the cable (switch and heating element conductor). Although this embodiment is specifically discussed in relation to jet drying, it should be understood that it can also be used with vacuum drying.

[0155] Various exemplary schematic diagrams and layouts of embodiments of the cleaning device system are shown in Figures 21a to 27b.

[0156] Figures 21a and 21b illustrate schematic diagrams and layouts of an embodiment of a cleaning device using jet drying. As shown, the cleaning device includes a battery, a CO2 cartridge, and a fluid reservoir. These can be housed in modules as described above. A power switch is provided for user actuation to turn on the battery and thus heat the heating element. The heating element can be, for example, a conformal resistance shaft heater. The heater can be a heating coil conduit that combines conduit, heating element, and temperature sensing into a single unit.

[0157] Two bidirectional valves are provided, actuated via buttons on the control panel. These bidirectional valves can be mechanical or solenoid valves. The first button activates the jet drying nozzle, and the second button activates the flushing nozzle. Each of the flushing and jet drying processes is powered by a CO2 cartridge. The flushing nozzle is fed fluid from a fluid reservoir.

[0158] Figures 22a and 22b illustrate the electrical control schematics and layout of an embodiment of a cleaning apparatus using vacuum drying. In the illustrated embodiment, an electronically controlled valve is used to achieve cyclic control. The fluid reservoir is pressurized relatively constantly. A downstream valve is provided and can be disposable.

[0159] Figures 23a and 23b illustrate a schematic diagram and layout of the mechanical controls for another embodiment of a cleaning apparatus using vacuum drying. In the illustrated embodiment, a mechanical control valve is used to operate the apparatus. A fluid reservoir is pressurized relatively constantly. A downstream valve is provided and can be disposable.

[0160] Figures 24a and 24b illustrate the electrical control schematics and layout of yet another embodiment of the cleaning apparatus using vacuum drying. In the illustrated embodiment, an electronically controlled valve is used to achieve cyclic control. A fluid reservoir is vented. An upstream valve is provided and can be reusable.

[0161] Figures 25a and 25b illustrate a schematic diagram and layout of the mechanical controls for another embodiment of the cleaning apparatus using vacuum drying. In the illustrated embodiment, a mechanical control valve is used to operate the apparatus. A fluid reservoir is vented. An upstream valve is provided and can be reusable.

[0162] Figures 26a and 26b illustrate schematic diagrams and layouts of embodiments of a cleaning device using suction supplied from an operating room. In such embodiments, no venturi valve, waste reservoir, or exhaust port is used. The CO2 cartridge may have a reduced size compared to a CO2 cartridge used in a cleaning device that uses suction but is driven by a CO2 unit. In the illustrated embodiment, an electronically controlled valve is used and implements cyclic control. The fluid reservoir is pressurized relatively constantly. A downstream valve is provided and may be disposable.

[0163] Figures 27a and 27b illustrate schematic diagrams and layouts of another embodiment of a cleaning device using suction supplied from an operating room. In this type of embodiment, no venturi valve, waste reservoir, or exhaust port is used. The CO2 cartridge may have a reduced size compared to a CO2 cartridge used in a cleaning device that uses suction but is driven by a CO2 unit. In the illustrated embodiment, an electronically controlled valve is used and implements cyclic control. The fluid reservoir is pressurized relatively constantly. A downstream valve is provided and may be disposable.

[0164] Figures 28a and 28b show a soiled sight glass and the soiled sight glass after an initial rinse using the cleaning apparatus described herein at 5 psi rinsing and 40 psi jet drying. Figures 29a to 29c show a sight glass before soiling, a soiled sight glass, and a cleaned sight glass, wherein the soiled sight glass was cleaned using the cleaning apparatus described herein.

[0165] Generally, the following parameters can be considered when selecting a combination from the above options:

[0166] • Nozzle geometry in the flushing channel;

[0167] • Nozzle geometry in the jet drying channel;

[0168] • Heating (power consumption, heater geometry, etc.);

[0169] • Rinsing time of the cleaning cycle;

[0170] • Spray drying time of the cleaning cycle;

[0171] • The volume of liquid used for cleaning circulation; and

[0172] • The volume of CO2 used for cleaning cycles.

[0173] As used herein, the term "substantially" or "substantially" refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, a "substantially" or "substantially" closed object would mean that the object is completely or nearly completely closed. The precise tolerance for deviation from absolute completeness may vary in some cases depending on the specific circumstances. However, in general, a closeness to completion will have an overall result that is as if absolute and complete completion had been achieved. The use of "substantially" or "substantially" also applies when used in a negative sense to refer to the complete or nearly complete absence of an action, characteristic, property, state, structure, item, or result. For example, an element, combination, embodiment, or composition that is "substantially non-existent" or "substantially non-existent" may still actually contain such an element, as long as the element has no significant effect overall.
