Embodiments of the disclosure relate to a multiple element cover to a tip section of a multi-camera endoscope.
Endoscopes have attained great acceptance within the medical community since they provide a means for performing procedures with minimal patient trauma while enabling the physician to view the internal anatomy of the patient. Over the years, numerous endoscopes have been developed and categorized according to specific applications, such as cystoscopy, colonoscopy, laparoscopy, upper GI endoscopy and others. Endoscopes may be inserted into the body's natural orifices or through an incision in the skin.
An endoscope is usually an elongated tubular shaft, rigid or flexible, having a video camera or a fiber optic lens assembly at its distal end. The shaft is connected to a handle which sometimes includes an ocular for direct viewing. Viewing is also usually possible via an external screen. Various surgical tools may be inserted through a working channel in the endoscope for performing different surgical procedures.
Endoscopes, such as colonoscopes, that are currently being used, typically have a front camera for viewing the internal organ, such as the colon, an illuminator, a fluid injector for cleaning the camera lens and sometimes also the illuminator, and a working channel for insertion of surgical tools, for example, for removing polyps found in the colon. Often, endoscopes also have fluid injectors (“jet”) for cleaning a body cavity, such as the colon, into which they are inserted. The illuminators commonly used are fiber optics which transmit light, generated remotely, to the endoscope tip section. The use of light-emitting diodes (LEDs) for illumination is also known.
Among the disadvantages of such endoscopes are their limited field of view and their complicated packing of all the required elements, such as electronics and fiber optics together with fluid carrying elements, in the small sized endoscope tip section. Another problem with existing endoscopes is the difficult assembling of the gentle electronic components, which are often damaged by the assembling process itself. Another problem with existing endoscopes is the complicated sealing of the parts, specifically in the tip section of the endoscope. Sealing of the tip section remains a challenge particularly due to the complex environment in which the endoscope is intended to operate.
There is thus a need in the art for endoscopes, such as colonoscopes, that allow a broader field of view and also enable efficient packing, assembling and sealing of all necessary elements in the tip section while maintaining their function.
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope.

Tip section 100 generally includes an inner part 110 which includes electronics (such as cameras, a circuit board such as electronic circuit board 400, and illumination sources, such as LEDs), fluid channels (such as fluid channeling component 600) and a multi-element tip cover 700. Multi-element tip cover 700 is designed to fit over the inner parts of the tip section 100, and to provide protection to the internal components in the inner part. Multi-element tip cover 700 includes, according to this embodiment, three parts: a front component 710 configured to cover a front part of the tip section; a right side component 730 configured to cover a right side part of the tip section; and a left side component 750 configured to cover a left side part of the tip section, wherein the front, right side and left side components are configured to abut each other to cover the tip section in such way that they cover essentially all inner parts of the tip section.
Front component 710 includes hole, transparent surface, window, or opening 736 configured to align with (and accommodate) front optical assembly 236 of forward looking camera 116; optical windows 242a, 242b and 242c of LEDs 240a, 240b and 240c; distal opening 340 of a working channel 640; distal opening 344 of a jet fluid channel 644; and irrigation and insufflation (I/I) injector 346 having a nozzle 348 (aligning with opening 664 of fluid channeling component 600).
Left side component 750 includes hole, transparent surface, window, or opening 756b configured to align with (and accommodate) side optical assembly 256b of side looking camera 220b; optical windows 252a and 252b of LEDs 250a and 250b on both sides of optical assembly 256b; side I/I injector 266b adapted to align with side I/I opening 666b of fluid component 600. Also seen in
Right side component 730 includes similar elements (not shown) as left side component 750.
Left side component 750 and right side component 730 are each in a shape of essentially half a cylinder (without top and bottom).
Front component 710 has essentially a cup shape having two opposing arms 712 and 714 extending perpendicularly from the cup bottom 711 (which may also be referred to as the cup's front face) and protruding from the cup edges. Upon assembling of the tip cover components, front component 710 may be installed first, and then the side components 730, 750 such that their long edges meet each other on both sides over arms 712 and 714 to assure sealing (
Multi-element tip covers according to embodiments of the specification, such as multi-element tip cover 700 or any other multi-element tip cover as disclosed herein, solve a significant problem that exists in the art when attempts are made to pack all necessary components into the small inner volume of an endoscope tip and to cover and seal these components. Regular cup shaped tip covers are used for standard tips having just one front camera. However, when standard cup shaped tip covers are used to cover the multi-camera tip, protruding inner tip elements, such as lenses or other parts of the side optical assemblies, are often damaged during the sliding of the cover over them. Using a multi-element tip cover may solve this problem. In addition, a multi-element tip cover assists in aiming its holes/openings/windows exactly at their right place over the corresponding tip inner elements. This is almost impossible using a unitary piece cover. Moreover, separately sealing each one of the elements of the multi-element tip cover improves the overall sealing of the tip due to better access to each element (for example an optical window) compared to the limited access of the same element in a unitary piece cover, such as a cup shaped cover. Separately sealing (and optionally checking for satisfactory sealing) of each one of the elements of the multi-element tip cover may be performed prior to assembling of the cover. This may also improve the sealing of the tip.
According to an embodiment of the current specification, tip section 100 of an endoscope comprises at least a forwards looking camera and at least one side looking camera. Tip section 100 is turnable by way of a flexible shaft (not shown) which may also be referred to as a bending section (for example, a vertebra mechanism).
In some embodiments, the front-looking camera and/or any of the side-looking cameras comprises a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) image sensor.
Tip section 100 includes front optical lens assembly 236 of forward looking camera 116. An optical axis of forwards looking camera 116 is substantially directed along the long dimension of the endoscope. However, since forward looking camera 116 is typically a wide angle camera, its Field Of View (FOV) may include viewing directions at large angles to its optical axis. It should be noted that the number of illumination sources, such as LEDs, used for illumination of the FOV may vary (for example, 1-5 LEDs may be used on a front face of tip section 100). Distal opening 340 of a working channel 640 is also located on the front face of tip section 100, such that a surgical tool inserted through working channel tube, and through the working channel 640 in the endoscope's tip section 100 and deployed beyond the front face may be viewed by forward looking camera 116.
Distal opening 344 of a jet fluid channel 644 is also located on the front face of tip section 100. In embodiments, distal opening 344 of a jet fluid channel 644 is be used for providing high pressure jet of fluid such as water or saline for cleaning the walls of the body cavity.
Also located on the front face of tip section 100 is an irrigation and insufflation (I/I) injector 346 having a nozzle 348 aimed at front lens optical assembly 236. In embodiments, I/I injector 346 is used for injecting fluid (liquid and/or gas) to wash contaminants such as blood, feces and other debris from front lens optical assembly 236 of forward looking camera 116. Optionally, the same injector is used for cleaning front lens optical assembly 236 and one, two or all of optical windows 242a, 242b and 242c. In embodiments, I/I injector 346 is fed by fluid such as water and/or gas which may be used for cleaning and/or inflating a body cavity.
Visible on a left side of tip section 100 is the side camera (side looking camera) element 256b of side looking camera 220b and optical windows 252a and 252b of LEDs 250a and 250b for camera 220b. A second side looking camera (not shown) is positioned on the right side of the tip and can be similar to camera 220b. Optical axis of the second side looking camera is substantially directed perpendicular to the long dimension of the endoscope. Optical axis of side looking camera 220b is substantially directed perpendicular to the long dimension of the endoscope. However, since side looking camera 220b and the second side looking camera are typically wide angle cameras, their fields of view may include viewing directions at large angles to their optical axes.
Side I/I injector 266b having a nozzle 267b aimed at side optical lens assembly 256b may be used for injecting fluid to wash contaminants such as blood, feces and other debris from side optical lens assembly 256b of side looking camera. In embodiments, the fluid includes gas which may be used for inflating a body cavity. Optionally, the same injector is used for cleaning both side optical lens assembly 256b and optical windows 252a and/or 252b. It is noted that according to some embodiments, the tip includes more than one window and LEDs, on the side and more than one window and LEDs in the front (for example, 1-5 windows and two LEDs on the side). Similar configuration of I/I injector and nozzle (not shown) exists for cleaning the optical lens assembly and optical windows (not shown) located on the other side of tip 100. The I/I injectors are configured to clean all or a part of these windows/LEDs. In various embodiments, left side I/I injector 266b, right side I/I injector (not shown), and front side I/I injector 344 are fed from the same channel in the fluid channeling component 600. In other embodiments, front side I/I injector is 344 is fed from a first fluid channel and left side I/I injector 266b and right side I/I injector are fed from a second, separate fluid channel in the fluid channeling component 600.
It is noted that the right side wall (not shown) and left side wall 362 have a form of an essentially flat surface which assists in directing the cleaning fluid injected from the right side I/I injector (not shown) and the left side injector 266b towards the right side optical assembly and windows and the left side optical assembly 256b and optical windows 252a and/or 252b respectively. Lack of such a flat surface may result in dripping of the cleaning fluid along the curved surface of tip section 100 of the endoscope without performing the desired cleaning action.
It should be noted that while only one side looking camera can be seen in
According to some embodiments, the circuit board used for carrying electronic components, such as cameras and/or LEDs, is a flexible circuit board that consumes less space and leaves more volume for additional necessary features. The flexibility of the board adds another dimension in space that can be used for components positioning.
The use of a flexible circuit board, according to embodiments of the specification, significantly increases reliability of the electric modules connection thereto as no wires are required for components connectivity. In addition, according to some embodiments, the components assembly can be machined and automatic.
The use of a flexible circuit board, according to some embodiments of the specification, also allows components (parts) movement and maneuverability during assembly of the camera head (tip of the endoscope) while maintaining a high level of reliability. The use of the circuit board, according to some embodiments of the specification, also simplifies the (tip) assembling process.
According to some embodiments, a flexible circuit board is connected to the control unit via a multi-wire cable. This cable is welded on the board in a designated location, freeing additional space within the tip assembly and adding flexibility to cable access. Assembling the multi-wire cable directly to the electrical components presents a major challenge which is mitigated by the use of the flexible board according to embodiments of the specification.

Tip section 1000 generally includes an inner part 1100 which includes electronics (such as cameras, a circuit board, and LEDs), fluid channels (such as fluid channeling component 1600) and a multi-element tip cover 1010. Multi-element tip cover 1010 is designed to fit over the inner parts of the tip section 1000 and to provide protection to the internal components in the inner part 1100. In various embodiments, the tip section 1000 comprises three parts/portions: a distal/front part 1102, a proximal part 1104 and a rear part 1105. Multi-element tip cover 1010 includes, according to this embodiment, two parts: a distal component 1050 configured to cover a distal/front part 1102 of the tip section and a proximal component 1030 configured to cover a proximal part 1104 of the tip section, wherein the distal component and the proximal component are configured to abut to cover the tip section 1000. Distal component 1050 has a shape of a cylinder having a side wall 1052 and a front face 1054, wherein front face 1054 is configured to cover a front part 1102 of inner part 1100 of tip section 1000 and proximal component 1030 has a shape of a cylinder having a side wall 1032 without a top or a bottom configured to cover a proximal part 1104 of inner part 1100 of tip section 1000. In accordance with an embodiment, the proximal component 1030 of the tip cover 1010 does not cover a rear part 1105 of the tip section 1000, but only the proximal part 1104. This enables connection between a bending section of the endoscope and the tip section 1000 to be on the rear part 1105 thereby effectively reducing the non-flexible portion of the bending section.

In yet another embodiment, the present specification discloses a multi-element tip cover that not only provides protection to the internal components of the endoscope tip, but also facilitates easy access to the internal components in the tip section, such that a component may be removed or replaced if required without having to remove the tip cover.
The present embodiments disclose a novel assembly approach of the tip cover on the distal tip and also provide a novel solution to the problem of replacing broken outer windows of the camera and illuminators. Additionally, efficient solutions are provided for replacing internal components of the distal tip, such as sensors, cables, illuminators, internal lenses, and other such components.
As shown earlier with reference to
In an embodiment, a multi-element tip cover is designed to fit over the inner part 1100 of the tip section 1000 and to provide protection to the internal components in the inner part 1100.
Thus, the removable window component 5050 is designed such that it can be removed to gain access to the window opening, through which the internal components of the tip can be accessed for repair or replacement, without removing the main component 5030. Therefore, for fixing or replacing one or more components of the inner part of the tip section, such as an LED, an optical element or any other element, the entire tip is not opened or exposed. Further, the main component 5030 of the tip cover remains intact and protects the packing and sealing of the tip section from damage. In various embodiments, the removable window component 5050 comprises a surface area in a range of 30 to 85% of the total surface area of the cylindrical side wall 5055 of the tip cover 5000. In various embodiments, an aspect ratio of width to length of the removable window component 5050 is in a range of 1:6. In various embodiments, when the removable window component 5050 is in place on said main component 5030, the windows of the removable window component 5050 and the underlying optical elements and/or LEDs are aligned such that a distance from the windows of the removable window component 5050 to the underlying optical elements and/or LEDs is in a range of 0 to 3 millimeters, and any increment therein, preferably 0 to 1 millimeters.
In an embodiment, the multi-element tip cover comprises three window openings with removable window components—one on the front for accessing front viewing element and other components located in the front section of the distal tip and one each on the two sides for accessing the corresponding side viewing elements and other components located on the two sides of the distal tip. The front removable window component comprises a surface area in a range of 20 to 85% of the total surface area of the front distal surface of the tip cover and the side window components each comprise a surface area in a range of 30 to 85% of the total surface area of the cylindrical side wall of the tip cover. In various embodiments, the front removable window component has any one of a circular, oval (as described with reference to
In another embodiment (shown in
In yet another embodiment, the multi-element tip cover comprises a front window opening with removable front window component and only one side window opening with removable side window component. The front window opening component comprises a surface area in a range of 20 to 85% of the total surface area of the front distal surface of the tip cover and the side window component comprises a surface area in a range of 30 to 85% of the total surface area of the cylindrical side wall of the tip cover. An aspect ratio of width to length of the front window component is in a range of 1:6 and an aspect ratio of width to length of the side removable window component is in a range of 1:6. When the front removable window component and side removable window component are in place, the windows or openings of the front removable window component and the underlying optical elements and/or LEDs are aligned such that a distance from the windows or openings of the front removable window component to the underlying optical elements and/or LEDs is in a range of 0 to 3 millimeters, and any increment therein, and the windows or openings of the side removable window component and the underlying optical elements and/or LEDs are aligned such that a distance from the windows or openings of the side removable window component to the underlying optical elements and/or LEDs is in a range of 0 to 3 millimeters, and any increment therein.
Referring to
In other embodiments, the front face 5080 of the tip cover 5000 further includes a distal opening of a working channel, distal opening of a jet fluid channel, and I/I injector aligning with an opening of a fluid channeling component. For the purpose of clarity and simplicity, these openings are not shown in
A front panel 5080c is positioned on a front end of the tip cover 5000c. The front panel 5080c comprises a window or opening 5236c for a front optical lens assembly, optical windows 5250a, 5250b and 5250c for front illuminators, a working/service channel opening 5022c, a nozzle opening 5024c and a jet opening 5026c.
It may be noted that the overall shape of the distal tip is substantially round, yet the side components including the side camera, LEDs, and jet are placed in flat depression 5028c. This flat depression 5028c is located on a surface of the side removable window component 5050c.
In an embodiment, multi-element tip cover 5000c has one side removable window component 5050c on one side. In another embodiment, multi-element tip cover 5000c has more than one side removable window component on its tip side surfaces to enable easy access to the internal components in the tip section, such that a component may be removed or replaced if required without having to remove the entire tip cover 5000c.
In an embodiment, the main component portion 5030c comprises edges 5070d about the side panel opening or recess 5055c that are adapted to couple to the side removable window component, in a manner such that the side removable window component may easily be put on to cover the side panel opening or recess 5055c and may also be easily removed. In an embodiment, the side removable window component may be coupled to the edges 5070d of the main component portion 5030c by any suitable coupling means known in the art, such as but not limited to screws, hinges, hooks, adhesives or welding. Optionally, in some embodiments, wherein an endoscope includes side viewing elements on both sides of a tip section, the tip cover 5000c includes another side panel opening or recess 5065c positioned on the opposite side of side panel opening or recess 5055c and another side removable window component similar to the side window component 5050c for side panel opening or recess 5065c.
In an embodiment, the main component 6030 further includes a groove 6032 on its side surface 6055 and complementary extensions off the sides of the removable window component that mate thereto. The groove 6032 is designed such that removable window component 6050 may be slid along groove 6032, longitudinally along a length of the endoscope tip, to expose the window opening and the components of the inner part of the endoscope tip when required. Thus, when one of the internal components of the tip section is to be repaired or replaced, the side window component 6050 is slid longitudinally along the groove 6032 to reveal the window opening, which provides access to the desired internal component. It should be appreciated that the groove could alternatively be on the removable window component 6050 and the mating members could be extending out from the main component 6030 into the window opening.
It may be noted that in an embodiment, a part of side window component 6050 has the form of an essentially flat surface which assists in directing the cleaning fluid injected from injector channel towards side optical assembly and optical windows. Lack of such a flat surface may result in dripping of the cleaning fluid along the curved surface of tip section of the endoscope without performing the desired cleaning action.
In an embodiment, windows or openings 6004, 6006, 6008 for the camera and illuminators of the endoscope tip (not shown in
In an embodiment, groove 6032 extends, alongside the surface 6055, from a proximal end of the side window component 6050 to the proximal end 6040 of the tip cover 6000, where the tip is connected to the endoscope tube. The side window component 6050 may be slid along said groove 6032, in a proximal direction, to move it away and reveal the window opening when required. Referring to

In various embodiments, side window components 6050 and 6150 of
In an embodiment, side removable window component 8050 is produced by insertion molding of illuminators windows 8150a and 8150b and the outer window 8156 of viewing element 8256. In an embodiment, instead of a window 8156, the lens of the viewing element is molded into the side removal window component 8050. It may be appreciated that the location of the optical windows (8156, 8150a and 8150b) in the side removable window component 8050 is designed to align with the location of the viewing element and the illuminators (8256, 8250a and 8250b, respectively) of the inner part 8100 of the tip section.
