Description
Technical Field
The present invention relates generally to medical devices for use in endoscopic procedures for human tissue inspection, as well as for urinary and gynecological disorders. And more particularly to a portable, hand-held, low cost surgical endoscopic device having a disposable portion and a reusable portion.
Background
Conventional endoscopy, or in the case of visual inspection of an organ or human interior, typically uses a complex lens system to transfer the image from the front end of the endoscope to the viewer. Rigid endoscopes typically use a relay lens system, while flexible endoscopes typically use a fiber optic bundle or objective lens system. Conventional rigid and flexible endoscopes, lenses or fiber optic systems are relatively expensive and are reused many times. Therefore, it must be strictly sterilized and disinfected after each use.
Disposable endoscopes are an emerging category of endoscopic instruments. In some cases, the manufacturing cost of the endoscope may become inexpensive enough to be used with only a single patient. Disposable or single use endoscopes reduce the risk of cross-contamination and hospital-set disease. Some disposable endoscope systems are described in U.S. Pat. Nos. 9,895,048, 9,895,848, 10,278,563, and 10,292,571.

All issued and filed patents mentioned in the detailed description are given reference indices in this patent specification.
Fig. 1 and 2 are right and top views of a portable endoscope having a disposable member according to some embodiments. The portable endoscope 100 includes an elongated cannula 120 with a front end 110 that is insertable into a hollow organ or cavity of a human body. According to some embodiments, front end 110 is connected to cannula 120 as a separate front terminal assembly. According to some embodiments, the diameter of the front end 110 is greater than about 4.55mm. For more details on the separate front terminal assembly of a hand-held endoscope, see U.S. patent No.9,895,048 (hereinafter "048 patent")), filed on publication No. 15/462,331,2017, 3-17, U.S. patent publication No. 2017-0188793A1 (hereinafter "331 application")), and filed on publication No. 2018, 1-23, PCT/US18/14880, international patent application No. WO0/2018/136950 (hereinafter "880 application"). Front end 110 includes an imaging module and at least one LED light source for viewing the interior of the organ or lumen into which front end 110 is inserted. Front end 110 also includes one or more fluid ports.
According to some embodiments, cannula 120 is rigid, flexible, or semi-flexible, and includes one or more fluid channels that are fluidly connected to port 132. The port 132 includes a luer fitting to allow a leak-free connection of the port 132 to various medical fluid components (not shown). One or more fluid channels or lumens in cannula 120 connect to one or more forward-facing fluid ports of forward end 110. According to some embodiments, one or more fluid channels or lumens in cannula 120 are also connected to back end ports 130 and 430. The back end ports 130 and 430 also include luer fittings to allow for leak-free connection with various medical fluid components (not shown). According to some embodiments, the rear end port 130 is substantially in line with the main longitudinal axis 124 of the cannula 120, thereby providing a substantially straight passthrough for a rigid or semi-rigid instrument. According to some embodiments, only one back-end port 130 is provided and the second back-end port 430 is omitted. The ease of instrument insertion and manipulation may be enhanced by port 130 through the instrument channel with a straight rear end portion. It has been found that the instrument ports (i.e., ports 130 and/or 430) can be configured to generally match the display module 150 and are perpendicular to the center of the display module 150, with significant ergonomic benefits. This arrangement makes it easier to insert a surgical instrument into port 130 or 430 and to manipulate the instrument because the instrument is in the same view and at the same angle as the display screen with respect to the user's eye. In particular, the short distance between the port and the display screen allows the operator to limit his/her visual range to a relatively small area. According to some embodiments, the distance d between the back end port (in this case, port 130) and the center of the screen 350 of the display module 150 is less than about 15cm. According to some embodiments, the distance d is less than about 12cm. According to some embodiments, the distance d is less than about 10cm.
According to some embodiments, all three ports 130, 132, and 430 are connected to the same lumen or channel within cannula 120, and in other embodiments, the ports are connected to two or more separate lumens. One or more "duckbill" or similar valves may be used to prevent backflow or leakage when two or more ports are connected to the same lumen in cannula 120. According to some embodiments, wires extending from the LED light sources and camera modules in front end assembly 110 connect electrical connectors 136 through separate channels within one cannula 120, with at least 1 fluid channel within cannula 120. The electrical connector 136 is configured to form a detachable electrical connection with a handle electrical connector 144 on the handle 140. In the vicinity of the fluid port 132 are a seat 134 and a socket 138. According to some embodiments, the receptacle 138 is a sliding (i.e., snap) fit with a side slot in the handle 140 (see side slot or slot 440 in fig. 4A).
The endoscope 100 includes a handle 140 that is pistol-shaped in size and shape to be easily grasped in the manner of a gun by an endoscope operator (e.g., a doctor or other medical professional). The display module 150 is rotatably and/or pivotably mounted on the handle 140 by means of bearings, which may be slide bearings made of plastic and rubber-wrapped hinges. An image capture button 142 is also visible on the handle 140. According to some embodiments, the handle 140 and the display module 150 may be reused and constitute the reusable portion 402 (shown in fig. 4A and 4B). According to some embodiments, the handle 140 includes one or more electronics modules 146 that include at least one of camera control, video capture, video processing, video/data storage, battery charging and control, touch screen processing, and WiFi communication. According to some embodiments, the electronics module 146 includes an electronic imaging system that supports automatic adjustment of parameters such As Exposure Control (AEC), gain control (AGO), and white balance (AWB). In addition, the electronics module 146 provides Automatic Light Control (ALC) to control the illumination of the object to be imaged. The camera and illumination modules in the front end 110, along with the imaging and control in the electronics module 146, are configured as a "well-conditioned" imaging system, providing a useful "auto mode". According to some embodiments, the handle 140 is similar to that shown and described in the ' 048 patent, the ' 331 application, and the ' 880 application, all of which are generally gun-type handles, which may contain electronic components and cooperate with a display, but differ significantly in the present application in the detachable connection and interaction of the handle 140 with the disposable member 400.
Fig. 3 is a perspective view of a portable endoscope having a side disposable member of some embodiments. The endoscope 100 shown in the figures includes only one back end port 130. In other embodiments, different disposable members 400 may be made according to the specific needs of the user. In some embodiments, the injection needle of the disposable member emerges from the cannula tip in a manner similar to that described in U.S. patent No.10,278,563, or the cannula of the disposable member has a flexible front end similar to that described in U.S. patent application Ser. No. 16/447,251 filed on 6/20 of 2019, or the cannula of the disposable member includes a working channel through which a surgical instrument can pass, or the cannula front end of the disposable member is made to scratch or otherwise collect a tissue sample similar to that described in U.S. patent No.8,460,182. As indicated by the dashed arrow, according to some embodiments, cannula 120 may be rotatable about its longitudinal axis 124.
Fig. 4A and 4B are further perspective views of a portable endoscope with a side-mounted disposable member in some embodiments. Fig. 4A more clearly shows a single-use disposable member 400 and a multi-use reusable portion 402 of endoscope 100. Single-use portion 400 includes cannula 120, front end 110, electrical connector 136, ports 130, 132, and 430, and hub 138. The reusable portion 402 includes the handle 140 and the display module 150. Single-use portion 400 slides or snaps into the sides of reusable portion 402 in a radial direction along longitudinal axis 124 as indicated by the dashed arrow. In particular, the receptacle 138 of the single-use portion 400 is sized to closely fit but be removable with the side slot 440 in the handle 140 of the reusable portion 402. The mating connection of the insert housing 138 with the side slots 440 provides a secure physical connection between the single-use portion 400 and the reusable portion 401. The electrical connection between the two portions 400 and 402 is established using the electrical connector 136 and the handle electrical connector 144. Advantages of separating the physical connection from the electrical connection have been found to include better resistance to fluid contamination of the electronic components, and easier, more intuitive mating of the single-use portion and the reusable portion. In addition, this type of electrical connection may be conveniently selected to connect single-use portion 402 to an electronic unit such as a cabinet, rather than handle 140. The cabinet may contain computing devices and displays, or other image processing and/or image storage devices, or devices that transmit images from 402 to a remote location (e.g., a hospital workstation or a telemedicine facility). According to some embodiments, the electrical connector 136 connects to the single-use portion 400 via a flexible cable 414 and enables the cannula to rotate as indicated by the dashed arrow in fig. 3. The front end portion of cable 414 is inside cannula 120, but the rear end portion is outside, exposed to the environment, and is of sufficient length and flexibility to allow cannula 120 to rotate relative to base 134 and handle 140.
Fig. 4B shows more details of the physical and electrical connections between the single-use portion and the reusable portion of portable endoscope 100. According to some embodiments, the electrical connectors 136 and 144 use standard electrical connection schemes such as micro display ports (type DP 20) for the 1 and 2 generation lightning interfaces. Fig. 4B shows a male connector 410 that mates with a female connector 144 on the handle 140. With respect to the mechanical connection, the receptacle 138 may include positioning aids, such as positioning balls 460, 462 and 464, which are spring loaded and may engage with the internal grooves 442 and 444 formed in the side grooves 440. In addition, posts 450 and 452 are provided on the receptacle 138 and apertures 470 and 472 are provided on the inside of the side slot 440 of the handle 140 to mate therewith.
FIG. 5 is an exploded view of a portable endoscope having a side-facing disposable member and a fluid resistant handle portion, depicting sealing components and other aspects, according to some embodiments. Many of the components of reusable portion 402 are sealed with O-rings and/or gaskets, including both left and right handle flaps 542 and 540 sealed to each other with corresponding O-rings or gaskets 532. Similarly, the front cover 550 and the rear cover 552 of the display module 150 are sealed using O-rings 534. The display module 150 and the left handle cover piece 542 are sealed using an O-ring 551. Various other openings are sealed with O-rings (e.g., O-ring 530). Similarly, the front cover 581 and the bottom cover or flap 583 may be sealed to the left and right handle flaps 540 and 542 by O-rings and/or gaskets.
Fig. 5 also shows a main printed circuit board 570 on which the electronic module 146 is mounted. The lithium ion rechargeable battery 580 supplies power to the electronic components, the display module 150, and the front-end camera module and the LED lamp through the electrical connector 144. In some embodiments, wi-Fi functionality is also included, as shown in fig. 5 for WiFi motherboard 582 and WiFi antenna 584.
Fig. 6 is a perspective view of a sealing structure and other aspects of a portable endoscope having a side disposable member in accordance with some embodiments. In this view, O-ring seals 532 and 534 are shown. The O-ring seal shown and described in fig. 5 and 6 provides a high degree of water resistance to the reusable portion 402 of the portable endoscope. For example, the handle 140 may conform to the IXP 7 standard and may be submerged from 0.15 meters to 1 meter below the liquid level for up to 30 minutes. After use, the reusable portion of the endoscope is sterilized and/or disinfected prior to reuse to prevent cross-contamination. The seal as shown and described employed by the reusable portion 402, according to some embodiments, can also have a level of fluid resistance in a fluid infiltrate such as alcohol for cleaning, sanitizing, and/or sterilizing. According to some embodiments, reusable portion 402 may be sterilized by immersion in Ethylene Oxide (EO) using a removable silicone plug (not shown) or otherwise sealing electrical connector 144. According to some other embodiments, reusable portion 402 can withstand repeated high pressure environments, such as a hot steam environment at 134 ℃.
Fig. 7 is a perspective exploded view of a cannula rotating structure and other portions of a portable endoscope with a side mounted disposable member, according to some embodiments. At the front end, the front end 110 is shown to include an end mount 710, two or more LEDs (LEDs 720 and 722 are shown as an example only), and a camera module 730. The rear end of cannula 120 is inserted into the front end of fluid collection chamber 732. The collection chamber 732 is secured at a rear end to the pedestal 134, and the pedestal 134 is secured at a rear end to the base 750. Within the housing 134 is an insertion tube connector 746, the front end of the insertion tube connector 746 being configured to be insertable into the rear end of the insertion tube 120. The rear end of the connector 746 is connected to a connector 744, which connector 744 may be attached to the connector 746 by threads and/or epoxy. The link 744 is connected to the working channel link 742. The base 750 is held in place by being "sandwiched" between the rear end of the channel connector 742 and the flange on the connector 740. The connector 740 is connected to the tube 754. The rear end of tube 754 is secured to luer port 756. Tube 754 is configured to freely rotate within receptacle 138. The receptacle 138 and electrical connector 136 remain stationary relative to the handle 140 while most other components rotate about the axis 124. In particular, according to some embodiments, front end 110, cannula 120, collection chamber 732, mount 134, connectors 746 and 744, working channel connector 742, base 750, connector 740, tube 744, and luer fitting 756 are rotated together as a unit about axis 124. According to some embodiments, the rotational amplitude of cannula 120 and other components is limited to slightly less than 360 degrees (e.g., 350 degrees as shown in fig. 8B, or at least 180 degrees) so that flexible cable 414 does not become too tight due to over-rotation. The base 750 may include a tab 752 that may be inserted into a circular slot 810 (shown in fig. 8A) on the front face of the flange of the receptacle 138.
Fig. 8A and 8B are a cross-sectional view and a front view of a portable endoscopic cannula rotation structure and other portions with a side-mounted disposable member in accordance with some embodiments. In some embodiments, circular slot 810 can limit rotation of cannula 120 and other components by limiting movement of base 750 tab 752 (shown in fig. 7). Note that since the cannula contains multiple lumens, the working channel in the cannula may be slightly off-center or off-axis 124. The link 744 allows the working channel to be more closely located to the centrally located longitudinal axis 124.
Fig. 9 is a side view of a WiFi antenna arrangement and other aspects of a portable endoscope with a side mounted disposable member in accordance with some embodiments. The locations of the WiFi motherboard 582 and the WiFi antenna 584 are shown. Note that WiFi antenna 584 may extend to and along the back of the touch screen of display module 150 to reduce the shielding effect of the metal portion of handle 140. According to some embodiments, the WiFi module and antenna 584 on the motherboard 582 may transmit video to a WiFi receiver (not shown), such as in another external monitor or workstation.
Fig. 10 is a perspective view of a touch sensitive video display screen according to some embodiments. As described above, the electronics module 146 in the handle 140 includes an electronic imaging system that supports automatic adjustment of parameters such As Exposure Control (AEC), gain control (AGC), and white balance (AWB). In addition, automatic illumination control (ALC) is integrated with ALC (automatic illumination control) for controlling illumination of the imaged object. The camera and illumination modules in the front end 110, along with imaging and control in the electronics module 146, together are configured as a "well-conditioned" imaging system, which can provide a useful "auto mode". However, in some cases, the use of a "manual mode" is sometimes advantageous, especially in endoscopy. In the hand-held portable endoscope 100, the automatic mode works well in most cases when the front end 110 is inside the cavity. But in some cases, for example, when the camera on the front end 110 is close to the inner wall of the tissue tangential to the line of sight of the camera module, the partial image field (due to the inner wall being close to the illuminating LED) is very bright compared to other areas farther from the LED. To better visualize the inner wall (or the portion near the camera head), a "manual mode" may be used, while all automatic imaging functions are turned off. In fig. 10, a switch button, such as one of the corner position buttons 1020, 1022, 1024, and 1026 on the touch screen 350, can switch or toggle the automatic mode and the manual mode. According to some other embodiments, hardware buttons on the handle 140 may be used in addition to or instead of the touch screen buttons to switch between automatic and manual modes. In addition, the "manual mode" may have a2 or 3 shift to reduce the LED brightness to facilitate visualization of the target surface. Such an automatic mode and manual mode arrangement is described in U.S. patent No.10,292,571.
According to some embodiments, the automatic mode is configured to enable full automatic AGC, AEC and ALC, while the manual mode turns off AGC, AEC and ALC and sets the LED brightness to 50% of its default brightness (or other preset brightness, e.g., 75%). Screen 350 is a non-contact or non-touch operation such that the clinical operator does not have to remove his glove to push and activate buttons on screen 150. According to some embodiments, buttons 1020, 1022, 1024, and 1026 are virtual touch buttons that float above display 350. As shown, they may be located near corners or edges of the screen. The user may move (slide) the "X" or "+" pattern laterally at position 1030 on screen 350 to close and hide the floating button. The user may dial the floating button in a circular motion (not shown) on the screen.
Fig. 11A and 11B are cross-sectional views of an insertion tube in some embodiments, and a cross-sectional view of a front end portion of a portable endoscope having a side-mounted disposable member. Fig. 11A illustrates some example dimensions of cannula 120. Cannula 120 has an outer diameter of 4.1 millimeters. The working channel lumen inner diameter is 2.2 millimeters and the cable lumen 1102 is oval in shape and size as shown. The cable lumen 1102 may be used to carry cables to the camera module and LEDs on the front end 110. In fig. 11B, the size and position of camera module 730, leds 720 and 722 are shown. The side length of the square area of the camera module 730 is 1.05mm, and the LEDs 720 and 722 are rectangular, and the long side length thereof is approximately the same as the side length of the camera 730.
According to some embodiments, the endoscope 100 described herein may be applied to gynecological diseases. For example, an endometrial biopsy device like Pipelle, an endometrial biopsy cannula like SoftFlex provided by Intel Hiragana Life sciences, new Jersey (INTEGRA LIVE SCIENCES Corp.), an endometrial sampler (EndoSampler) such as Meter gold, illinois (MedGyn), and a surgical curet, etc., may be inserted through the working channel into the body for an endometrial biopsy.
Although the foregoing has been described in some detail for purposes of clarity of illustration, it will be apparent that certain changes and modifications may be practiced without departing from the principles of the invention. It should be noted that there are many alternative ways of implementing the processes and apparatuses described herein. Accordingly, the present embodiments are to be considered as illustrative and not restrictive, and the body of work described herein is not to be limited to the details given herein, but may be modified within the scope and equivalents of the appended claims.
