Description

Method and system for real-time monitoring and cleaning of laparoscopic lenses
Technical Field
The present disclosure relates to a surgical device for use in minimally invasive surgical procedures, such as endoscopic and/or laparoscopic procedures, and more particularly to a system and method for monitoring and cleaning the lens of an endoscope or laparoscope.
Background
Minimally invasive surgical procedures, such as endoscopic surgery, reduce the invasiveness of the surgical procedure. Endoscopic surgery involves surgery through the body wall, for example, to view and/or operate on the ovary, uterus, gallbladder, intestines, kidney, appendix, etc. There are many common endoscopic surgical procedures including, for example, arthroscopy, laparoscopy, gastroenterology, and laryngobronchoscopy. In these methods, an incision is made using a puncture instrument, and endoscopic surgery is performed through the incision. The piercer tube or cannula assembly extends into and remains in the abdominal wall to provide access to the endoscopic surgical tool. A camera or endoscope is inserted through the cannula assembly to allow visual inspection and magnification of the body cavity. The surgeon may then perform diagnosis and/or treatment at the surgical site with the aid of specialized instruments (such as forceps, graspers, cutters, applicators, etc.) designed to fit through the additional cannula.
In use, the lens of the endoscope may become covered by condensation, tissue, blood, other bodily fluids, and the like. It is therefore difficult to keep the lens of the endoscope clean during the procedure, and the time required to clean the endoscope during the procedure may increase both the total time of the procedure and the amount of time the patient needs to remain under anesthesia, both of which may result in increased risk of infection and increased recovery time.

Detailed Description
Lens monitoring and cleaning systems and methods are described in detail with reference to the drawings, wherein like reference numerals designate identical or corresponding elements in each of the several views. As used herein, the term "distal" refers to portions of the penetrator or components thereof that are farther from the user, while the term "proximal" refers to portions of the penetrator or components thereof that are closer to the user. In addition, the term "laparoscopic" or "laparoscope" is used generally to refer to endoscopes, laparoscopes, arthroscopes, and/or any other procedure performed through a small diameter incision or cannula. As used herein, the term "about" means that the numerical values are approximate and that small variations will not significantly affect the practice of the disclosed aspects of the disclosure. Where numerical limitations are used, "about" means that the numerical values can vary by ± 10% and still be within the scope of the disclosure, unless the context indicates otherwise.
Disclosed herein are systems and methods for intelligently real-time self-cleaning a laparoscopic lens intraoperatively, for example, during a surgical procedure. As will be described in greater detail below, the system and method employ real-time monitoring and analysis of image quality to maintain image sharpness. The system monitors the image sharpness through the lens of the laparoscope and if the image sharpness is below a predetermined threshold, the system will send a feedback signal to the cleaning system, which will initiate the cleaning process. The system and method maintains a clean lens intraoperatively in real time and automatically, thereby maintaining, for example, image clarity, shortening surgical time, and reducing risks.
Fig. 1 illustrates a flow diagram of a monitoring and cleaning system according to aspects of the present disclosure, shown generally as monitoring and cleaning system 100. The monitoring and cleaning system 100 comprises: a monitoring system 200 for monitoring the image sharpness and identifying when the image sharpness falls below a predetermined threshold; a cleaning system 300 that is activated in response to receiving a feedback signal provided by the monitoring system 200; and an access assembly 400, the laparoscope 212 of the monitoring system 200 being received by the access assembly 400, and the access assembly 400 being configured for operation with the monitoring system 200 and the cleaning system 300.
The monitoring system 200 may include a laparoscope 212 and a laparoscopic imaging system 210. The laparoscopic imaging system 210 may be configured to monitor image sharpness through the lens 214 of the laparoscope 212 and provide a feedback signal to the cleaning system 300 when the image sharpness falls below a predetermined threshold. For example, the monitoring system 200 may include a separate processor 220 that monitors image sharpness and initiates lens cleaning.
In an aspect of the present disclosure, the laparoscopic imaging system 210 may include a monitoring module for determining whether the image sharpness is below a predetermined threshold. In particular, the monitoring module compares the real-time single frame image to a sharpness comparison template. If the image sharpness is below a predetermined threshold, the laparoscopic imaging system 210 communicates with the cleaning system 300, for example, outputting a signal to the cleaning system 300. In one aspect of the present disclosure, if the program shows a "yes" signal, the cleaning system 300 automatically starts and runs a lens cleaning program. In another aspect of the present disclosure, if the program shows a "yes" signal, the monitoring and cleaning system 100 requires the surgeon, nurse or support personnel to confirm whether a lens cleaning program can be initiated and run. In yet another aspect of the present disclosure, the surgeon, nurse, or support personnel may input instructions to the monitoring and cleaning system 100 to inhibit interruption when it is not desired that the surgical procedure be interrupted. In this aspect, if the program shows a "yes" signal, the monitoring and cleaning system 100 first checks whether there is an instruction to inhibit the interruption; if there is an interrupt disable instruction, the cleaning system 300 does not perform a lens cleaning procedure until the surgeon, nurse, or assistant cancels the interrupt disable instruction; if there is no instruction to inhibit the interruption, the cleaning system 300 starts and runs a lens cleaning program.
The laparoscopic imaging system 210 and/or the independent processor 220 may comprise any suitable processor (not shown) operably connected to a memory (not shown), which may comprise one or more of the following: volatile, nonvolatile, magnetic, optical, or electrical media, such as Read Only Memory (ROM), Random Access Memory (RAM), Electrically Erasable Programmable ROM (EEPROM), nonvolatile RAM (NVRAM), or flash memory. The processor may be any suitable processor (e.g., control circuitry) adapted to perform the operations, calculations, and/or sets of instructions described in this disclosure, including but not limited to a hardware processor, a Field Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), a Central Processing Unit (CPU), a microprocessor, and combinations thereof. Those skilled in the art will appreciate that any logical processor (e.g., control circuitry) adapted to execute the monitoring modules, calculations and/or instruction sets described herein may be substituted for the processor.
The cleaning system 300 includes a positioning assembly 340 for positioning the distal end 212b of the laparoscope 212 within the cannula assembly 410 of the access assembly 400. In this manner, the lens 214 of the laparoscope 212 is enclosed within the sleeve assembly 410 to allow cleaning of the lens 214. The positioning assembly 340 may include a mechanism for advancing the sleeve assembly 410 toward the distal end 212b of the laparoscope 212 to enclose the distal end 212b of the laparoscope 212 within the sleeve assembly 410. Further, or alternatively, the positioning assembly 340 may include a mechanism for retracting the laparoscope 212 relative to the cannula assembly 410 to position the distal end 212b of the laparoscope 212 within the cannula assembly 410.
Cleaning system 300 includes a pressurized liquid source 310 (e.g., saline) to clean lens 214 and a compressed gas source 320 (e.g., CO) to dry lens 2142). In certain aspects of the present disclosure, the pressurized liquid source 310 is water spray, and the temperature of the water is about 37 ℃, and the salinity of the water is from about 8,000ppm to about 10,000ppm or from about 0.8% to about 1.0%. Similarly, the CO of gas source 320 is compressed2Or other gases may also have a temperature of about 37 c to prevent fogging.
To maintain equilibrium within cannula assembly 410 during the cleaning and drying processes, cleaning system 300 includes a source of negative pressure or suction 330, e.g., a vacuum source. As will be described in more detail below, the suction source 330 is activated during activation of the pressurized liquid and/or compressed gas source to equalize the pressure within the access assembly 400 and remove water and CO for cleaning and drying the lens 2142。
Optionally, the cleaning system 300 includes a positioning assembly 340 that positions the distal end 212b of the laparoscope 212 within the cannula assembly 410 of the access assembly 400. In this manner, the lens 214 of the laparoscope 212 is enclosed within the sleeve assembly 410 to allow cleaning of the lens 214. The positioning assembly 340 may include a mechanism for advancing the sleeve assembly 410 toward the distal end 212b of the laparoscope 212 to enclose the distal end 212b of the laparoscope 212 within the sleeve assembly 410. Additionally, or alternatively, the positioning assembly 340 may include a mechanism for retracting the laparoscope 212 relative to the cannula assembly 410 to position the distal end 212b of the laparoscope 212 within the cannula assembly 410.
Fig. 2 illustrates a flow diagram of a method in accordance with aspects of the present disclosure. As described above, the monitoring system 200 may be a laparoscopic imaging system 210 for monitoring the image sharpness of an image provided through a lens 214 (FIG. 1) of a laparoscope 212 and identifying when the image sharpness falls below a predetermined threshold. The laparoscopic imaging system 210 is also configured to provide a feedback signal to the cleaning system 300 (fig. 1) when the image sharpness falls below a predetermined threshold.
In response to the monitoring system 200 determining that the image sharpness falls below a predetermined threshold and the feedback signal alerts the cleaning system 300 that the image sharpness has fallen below the predetermined threshold, the cleaning system 300 activates to clean the lens 214 of the laparoscope.
Before cleaning the lens 214 of the laparoscope 212, if the distal end 212b of the laparoscope 212 is not already positioned within the access assembly 400 (e.g., the distal end 212b of the laparoscope 212 is located proximal to the vacuum seal 450 (fig. 5) on the distal portion 416 of the cannula assembly 410 of the access assembly 400), then at least one of retracting the laparoscope 212 and advancing the cannula assembly 410 is performed. Either or both of these actions may be envisaged as being performed manually or automatically. When retraction/advancement is automatic, the cleaning system 300 may include a positioning assembly 340 for positioning the distal end 212b of the laparoscope 212 relative to the vacuum seal 450 of the cannula assembly 410, as described above.
After confirming that the distal end 212b of the laparoscope 212 of the monitoring system 200 is positioned within the cannula assembly 410 distal of the vacuum seal 450, the pressurized liquid source 310 is activated to spray the distal end 212b of the laparoscope 212 (containing the lens 214) and the lens 214 is cleaned with a water jet. As noted above, in certain aspects of the present disclosure, the water spray comprises water having a temperature of about 37 ℃ and a salinity of between about 8,000ppm and about 10,000ppm or between about 0.8% and about 1.0%, and in certain aspects, preferably about 9,000ppm or 0.9% salinity. The length of time that the pressurized liquid source is activated may be based on the sharpness of the image before initiating the cleaning system 300. The lower image resolution produced by the conventional laparoscopic imaging system 210 may result in a longer period of activation of the pressurized liquid source 310, while the period of activation of the pressurized liquid source 310 may be shorter for image resolutions at or slightly above the threshold.
The suction source 330 is activated simultaneously with the pressurized liquid source 310. By activating the pressurized fluid source 310 simultaneously with activating the suction source 330, equilibrium is maintained within the cannula assembly 410 and the integrity of the enclosed space provided by the vacuum seal 450 is maintained.
After pressurized liquid source 310 has been activated for a predetermined amount of time, based on image clarity or other factors, pressurized liquid source 310 is deactivated and compressed gas source 320 is activated. In certain aspects of the disclosure, CO is compressed2Has a temperature of 37 ℃ to match the temperature of the water from the pressurized liquid source 310 to prevent fogging of the lens 214 of the laparoscope 212. The suction source 330 remains active during activation of the pressurized liquid source 310 to maintain equilibrium within the cannula assembly 410.
After a predetermined period of time and complete desiccation of the lens 214 of the laparoscope 212, both the compressed gas source 320 and the suction source 330 are deactivated. After cleaning the lens 214 of the laparoscope 212, the laparoscope 212 is ready for continued use.
The entire cleaning process is preset to ten seconds (10s) from the determination that the image sharpness falls below a predetermined threshold to the completion of the drying of the lens 214 of the laparoscope. The cleaning process may be preset to take more or less than ten seconds (10 s). The systems and methods disclosed herein may be preset to extend to robotic surgical systems to maintain image quality.
The systems and methods of the present disclosure are envisioned to enhance surgical efficiency, maintain image quality, reduce lens cleaning time and times, shorten surgical procedures and anesthesia time, and reduce the risk of infection due to cleaning the lens of the laparoscope away from the surgical site.
Fig. 3-6 illustrate an access assembly 400 and laparoscopic imaging system 210 and laparoscope 212 according to aspects of the present disclosure. Although the systems and methods of the present disclosure are illustrated with reference to access component 400, aspects of the present disclosure may be preset for modification for use with access components having alternative configurations.
As shown in fig. 5, the access assembly 400 includes a cannula 402 defining a lumen 403, and a cannula assembly 410 receivable through the lumen 403 of the cannula 402. Cannula assembly 410 has a lumen 412 through which lumen 412 a medical device (e.g., laparoscope 212) can be passed. The cannula assembly 410 includes a seal assembly 420, an elongate body 414, a distal portion 416, and a proximal portion 418. As shown in fig. 4, the seal assembly 420 includes a seal 422 and a securing collar 424 disposed therein, the securing collar 424 retaining the seal 422 within the seal assembly 420. Cannula assembly 410 also has an inlet port 430 and a vacuum port 440, inlet port 430 configured to operably engage pressurized liquid source 310 (fig. 1) and compressed gas source 320, and vacuum port 440 configured to operably connect with suction source 330.
The cannula assembly 410 also has a vacuum seal 450 (fig. 5-7) at the distal portion 416 of the cannula assembly 410. As shown in more detail in fig. 7, the vacuum seal 450 may be formed by a plurality of leaflets 452, the plurality of leaflets 452 allowing passage of the medical device therethrough, but the plurality of leaflets 452 will close the vacuum seal 450 when the medical device is removed therefrom. Further, the vacuum on the vacuum port 440 will hold the vacuum seal 450 in the closed position.
Figure 8 shows laparoscope 212 deployed from cannula assembly 410 through cannula 402. The vacuum seal 450 opens when the laparoscope 212 is passed therethrough. As shown in FIG. 8, the inlet port 430 is connected to an inlet tube 432 that terminates at an inlet opening 434 at the distal portion 416 of the cannula assembly 410. The inlet port 430, inlet tube 432, and inlet opening 434 allow for the introduction of liquids and/or gases into the distal portion 416 of the cannula assembly 410. Similarly, the vacuum port 440 is connected to an outlet tube 442 that terminates in an exit opening 444 at the distal portion 416 of the cannula assembly 410. The vacuum port 440, outlet tube 442, and exit opening 444 allow for the removal of liquids and/or gases from the distal portion 416 of the cannula assembly 410.
In use, as shown in more detail in fig. 9 and 10, the laparoscope 212 requiring cleaning is partially proximally retracted (indicated by arrows "a 1" and "a 2" in fig. 9) within the cannula assembly 410 such that the lens 214 of the laparoscope 212 is proximal to the vacuum seal 450. Vacuum is drawn by connecting the suction source 330 (fig. 1) to the vacuum port 440. The vacuum is pulled to form a tight seal with the vacuum seal 450.
Liquid and/or gas is then introduced through inlet port 430. The vacuum is drawn such that liquid and/or gas travels through the inlet tube 432 (as indicated by arrow "LG 1") and through the access opening 434 into the distal portion 416 of the cannula assembly 410 (as indicated by arrow "LG 2") where the liquid and/or gas contacts the lens 214 of the laparoscope 212 to remove any condensation, tissue, blood, other bodily fluids, etc. from the lens 214.
Continued vacuum causes the liquid, gas, and any other material(s) removed from the laparoscopic lens 214 to exit the distal portion 416 of the cannula assembly 410 (as indicated by arrow "V1"), through the exit opening 444 and through the exit tube 442 (as indicated by arrow "V2"), and out of the cannula assembly 410 through the vacuum port 440.
Although the system according to the present disclosure is inThe embodiment shown in fig. 1 is illustrated as mixing gas from the compressed gas source 320 with liquid from the pressurized liquid source 310 into the inlet port 430 of the cannula assembly 410 to clean and/or desiccate the lens 214 of the laparoscope 212, although the disclosure is not limited thereto. In an alternative embodiment, the low pressure generated within the lumen 412 of the cannula assembly 410 during cleaning and/or drying relative to the body cavity by the suction source 330 may be utilized to draw gas (such as CO) from the body cavity through the vacuum seal 4502) To act as a gas source to clean and/or dry the lens 214 of the laparoscope 212. In this case, a gas source, for example, for body cavity enlargement is used as the compressed gas source 320 of the system of the present disclosure, without having to provide an additional compressed gas source. Further, in this case, if the gas source for body cavity expansion is already in an activated state, the system according to the present disclosure also considers that the pressurized liquid source 310 is activated simultaneously with the gas source. In this process, the vacuum seal 450 essentially acts as a one-way valve. In other words, gas from the body cavity may enter the lumen 412 of the sleeve assembly 410 through the vacuum seal 450 to some extent to clean and/or dry the lens 214 of the laparoscope 212 and thus exit the access assembly 400 through the vacuum port 440, but the contents of the lumen 412 of the sleeve assembly 410 cannot enter the body cavity through the vacuum seal 450.
Any of the components described herein may be made from any metal, plastic, resin, composite, etc., in view of strength, durability, wear resistance, weight, corrosion resistance, ease of manufacture, cost of manufacture, etc. In various aspects, the elongated body of the cannula assembly may be made of a metal, such as stainless steel, and the seal may be made of a resilient plastic or rubber.
It should be understood that various modifications can be made to the disclosed methods and systems. Accordingly, the above description should not be construed as limiting, but merely as exemplifications of aspects of the disclosure. Other modifications will occur to those skilled in the art within the scope and spirit of the disclosure. For example, any and all features of one described aspect may be incorporated into another aspect as appropriate.
