Light processing adapter for endoscope

Abstract

An adapter for an endoscope system includes a housing, a light guide element, a sensor to receive light waves emitted from the light guide element, a transducer connected to the sensor to convert the light waves into an electrical signal including instructions to generate light with a light generator of the endoscope, and an electrical coupler connected to the transducer to transmit the electrical signal from the housing to the endoscope. A method for transmitting a light control signal from an imaging and control system to an endoscope having a light generating capability includes generating light with a light generator, receiving the light from the light generator at an adapter, sensing an intensity of the light with a sensor, converting the intensity sensed by the sensor into a light control signal for generating light with the light generator of the endoscope, and transmitting the light control signal to the light generator of the endoscope.

Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to U.S. Provisional Patent Application No. 63 / 382,644, filed November 7, 2022, and U.S. Provisional Patent Application No. 63 / 486,507, filed February 23, 2023, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure generally relates to medical devices comprising an elongated body configured to be inserted into an incision or opening in a patient’s anatomy to provide diagnostic or therapeutic procedures.

[0004] More specifically, this disclosure relates to systems and apparatus for establishing a connection between a medical device and an imaging and control system. Background Technology

[0005] Endoscopes can be used for one or more of the following: 1) providing access to various anatomical parts via other devices, such as treatment devices or tissue collection devices, and 2) imaging such anatomical parts. Such anatomical parts may include the gastrointestinal tract (e.g., esophagus, stomach, duodenum, pancreaticobiliary ducts, intestines, colon, etc.), the renal region (e.g., kidneys, ureter, bladder, urethra), and other internal organs (e.g., reproductive system, sinus cavities, submucosal regions, respiratory tract), etc.

[0006] Conventional endoscopes can be used for a variety of clinical procedures, including, for example, illuminating, imaging, detecting and diagnosing one or more disease states, delivering fluids toward an anatomical area (e.g., delivering saline or other preparations via a fluid channel), providing access to one or more therapeutic devices (e.g., via a working channel) for sampling or processing an anatomical area, and providing aspiration access for collecting fluids (e.g., saline or other preparations).

[0007] In conventional endoscopy, the distal portion of the endoscope can be configured to support and orient a treatment device, for example, using a lifter. In some systems, two endoscopes can be configured to work together, with the first endoscope guiding a second endoscope inserted within it using a lifter. Such systems can facilitate guiding endoscopes to hard-to-reach anatomical locations within the body. For example, some anatomical locations can only be accessed using an endoscope after inserting it via a circuitous route. For instance, duodenoscopy (e.g., endoscopic retrograde cholangiopancreatography, hereinafter referred to as “ERCP”) involves the use of an auxiliary endoscope (also called a daughter endoscope or cholangioscope) that can be advanced through the working channel of the master endoscope (also called the mother endoscope or duodenoscope). Additionally, another device, such as a tissue retrieval device for biopsy, can be inserted into the auxiliary endoscope. Typically, the duodenoscope, auxiliary endoscope, and tissue retrieval device gradually decrease in size because these endoscopes are constructed in a nested, telescoping arrangement. Typically, after each use, the duodenoscope, auxiliary endoscope, and tissue retrieval device are cleaned and sterilized for reuse. Therefore, the imaging and control system, with its light generator, image processing capabilities, and therapeutic functions, is usually configured for reuse with one or more endoscopes and instruments of the same type. Summary of the Invention

[0008] This disclosure recognizes that the problems to be addressed by surgical systems include the need to make disposable endoscopes compatible with existing imaging and control systems. There has recently been a desire to utilize disposable endoscopes to, for example, eliminate the need for cleaning, sterilizing, and reprocessing reusable endoscopes. However, many key devices, such as light generators, image processing equipment, and treatment devices, are configured for use with reusable endoscopes that have specific compatibility, such as illumination and imaging system compatibility. In particular, many endoscopes include light transmission capabilities, such as light conductors or light channels, which transmit light generated at the imaging and control system to the distal endoscope for dissection. Therefore, the operator of the endoscope can control the imaging and illumination characteristics of the endoscope from the imaging and control system. Therefore, there is a need to produce disposable endoscopes that are both compatible with existing imaging and control systems and inexpensive.

[0009] This disclosure provides solutions to these and other problems by providing systems, apparatus, and methods associated with an adapter that transmits illumination commands from an imaging and control system to an endoscope, particularly a disposable endoscope with an onboard light generator. It may be desirable to produce disposable endoscopes that include a light generator, such as a light-emitting diode (LED), instead of a light emitter. LED light generators may be cheaper than light emitters, such as optical fibers. Furthermore, optical fibers can be fragile and easily broken if handled improperly. However, removing the light conductor from the endoscope eliminates the ability of the imaging and control system to control the light output at the distal end of the endoscope. For example, commands input to the imaging and control system for the light generator in the imaging and control system will not change the light generated by the light generator in the endoscope because no electrical signal from the light generator in the imaging and control system is transmitted to the endoscope. According to this disclosure, an endoscope adapter can be configured to provide illumination commands to a light generator within the endoscope based on illumination commands input to the imaging and control system. In examples, the adapter of this disclosure may include one or more light sensors that convert light generated by the imaging and control system and transmitted to the adapter into commands for the light generator in the endoscope. One or more sensors can sense parameters of light generated at the imaging and control system and convert the sensed parameters into instructions for a light generator in the endoscope to generate light with the same parameters. In a specific example, a light intensity sensor can be used to measure or sense the intensity of light transmitted from the imaging and control system to the adapter, and then convert the sensed intensity into electronic instructions for generating light using the light generator in the endoscope. Furthermore, a light color sensor can be used to measure or sense the color of light transmitted from the imaging and control system to the adapter, and then convert the sensed color into electronic instructions for generating light using the light generator in the endoscope. Therefore, existing imaging and control systems and associated operating procedures can be used with endoscopes having onboard light generators, including disposable endoscopes.

[0010] In the example, an adapter for an endoscope system may include: a housing; a light guide element extending into the housing; a sensor disposed within the housing to receive light waves emitted from the light guide element; a converter connected to the sensor to convert the light waves into electrical signals, the electrical signals including instructions for generating light using a light generator of the endoscope; and an electrical connector connected to the converter and accessible through the housing, the electrical connector being configured to transmit electrical signals from the housing to the endoscope.

[0011] In another example, the surgical endoscope system may include: an imaging and control system including a light source having a receptacle; an endoscope including an axis, a working channel, and a light generator, the axis including a connector at a proximal end portion and an imaging device at a distal end portion, the working channel extending at least partially through the axis, and the light generator configured to emit light near the distal end portion; and an adapter configured to connect to the receptacle, the adapter including a light sensor, a receptacle, and a converter, the light sensor being configured to receive light waves from the light source when the adapter is connected to the receptacle, the receptacle being configured to receive the connector of the endoscope, and the converter being configured to convert light intensity readings from the light sensor into instructions for operating the light generator.

[0012] In another example, a method for transmitting a light control signal from an imaging and control system to an endoscope having light-generating capabilities may include: generating light using a first light generator of the imaging and control system; receiving light from the first light generator at an adapter connected to the imaging and control system; sensing the intensity of the light using a sensor of the adapter; converting the intensity sensed by the sensor into a light control signal for generating light using a second light generator of the endoscope; and transmitting the light control signal to the second light generator of the endoscope via the adapter, wherein the light control signal is configured to instruct the second light generator of the endoscope to generate light of the same intensity sensed by the sensor.

[0028] Figure 1 This is a schematic diagram of an endoscope system 10, including an imaging and control system 12 and an endoscope 14. Figure 1System 10 is an illustrative example of an endoscope system suitable for use with the systems, apparatus, and methods described herein, such as with a light processing adapter. According to some examples, endoscope 14 can be inserted into an anatomical region for imaging and / or provide access to other devices, such as auxiliary endoscopes and biopsy devices, or one or more therapeutic devices, for the treatment of disease conditions associated with the anatomical region. In an advantageous aspect, endoscope 14 can be engaged with and connected to imaging and control system 12, for example, by inserting connector segment 36 into socket 37. In the illustrated example, endoscope 14 includes a duodenoscope, but other types of endoscopes can be used with the features and teachings of this disclosure.

[0029] The imaging and control system 12 may include a control unit 16, an output unit 18, an input unit 20, a light source unit 22, a fluid source 24, and a suction pump 26.

[0030] The imaging and control system 12 may include various ports for connection to the endoscope system 10. For example, the control unit 16 may include a data input / output port for receiving data from and transmitting data to the endoscope 14. Such data input / output may be provided through an interface between the connector section 36 and the socket 37. The light source unit 22 may include an output port for transmitting light, for example, via an optical fiber link, to the endoscope 14. For example, the connector section 36 may include a light conductor 39 ( Figure 2 The photoconductor 39 is configured to receive light from a lens or bulb within the light source unit 22. The fluid source 24 may include a port for transferring fluid to the endoscope 14. The fluid source 24 may include a pump and a fluid tank, or may be connected to an external tank, container, or storage unit. The suction pump 26 may include a port for creating a vacuum from the endoscope 14 to generate suction, such as for drawing fluid from the anatomical region into which the endoscope 14 is inserted. In one example, fluid, such as air, may be transferred to the endoscope 14 via an interface at the connector section 36 and the socket 37. In another example, fluid, such as water, may be directly input into the connector section 36 without flowing out of the socket 37. The output unit 18, such as a touchscreen display, and the input unit 20, such as a keyboard, may be used by the operator of the endoscope system 10 to control the functions of the endoscope system 10 and view the output of the endoscope 14. The control unit 16 may additionally be used to generate signals or other outputs by processing the anatomical region into which the endoscope 14 is inserted. In the example, the control unit 16 can generate electrical output, acoustic output, fluid output, etc., for processing the anatomical area by means of, for example, cauterization, cutting, freezing, etc.

[0031] The endoscope 14 may include an insertion section 28, a functional section 30, and a handle section 32, which can be connected to a cable section 34 and a connector section 36. The connector section 36 can be connected to a control unit 16 at a socket 37 to connect the endoscope 14 to various features of the control unit 16, such as the input unit 20 and the light source unit 22. The fluid source 24 and the suction pump 26 can be directly connected to the endoscope 14 without being routed through the control unit.

[0032] Insertion segment 28 extends distally from handle segment 32, and cable segment 34 extends proximally from handle segment 32. Insertion segment 28 may be elongated and includes a curved segment and a distal end that can be attached to functional segment 30. The curved segment may be controllable (e.g., via a control knob 38 on handle segment 32) to manipulate the distal end through tortuous anatomical pathways (e.g., stomach, duodenum, kidney, ureter, etc.). Insertion segment 28 may also include one or more working channels (e.g., lumens), which may be elongated and support the insertion of one or more therapeutic instruments, such as an endoscope, into functional segment 30. The working channels may extend between handle segment 32 and functional segment 30. Additional functions such as fluid access, guide wires, and traction wires may also be provided through insertion segment 28 (e.g., via aspiration or flushing pathways, etc.).

[0033] The handle section 32 may include a control knob 38 and a port 40A. The control knob 38 may be connected to a traction cable or other actuating mechanism extending through the insertion section 28. Port 40A and other ports, such as port 40B, are also included. Figure 2 It can be configured to connect various cables, guide wires, auxiliary mirrors, tissue collection devices, fluid tubes, etc. to the handle section 32 for connection with the insertion section 28.

[0034] According to the example, the imaging and control system 12 can be mounted on a mobile platform (e.g., a trolley 41) having a platform for accommodating the light source unit 22, the suction pump 26, and the image processing unit 42. Figure 2 Shelves such as ) etc. Alternatively, Figure 1 and Figure 2 Several components of the imaging and control system 12 shown can be directly mounted on the endoscope 14 so that the endoscope is "independent".

[0035] Functional section 30 may include components for processing and diagnosing the patient's anatomy. Functional section 30 may include an imaging device, an illumination device (e.g., the distal end of an optical fiber), and a lift. Operation of some or all features of functional section 30 is typically performed in imaging and control system 12.

[0036] Figure 2 yes Figure 1 A schematic diagram of an endoscope system 10, which includes an imaging and control system 12 and an endoscope 14. Figure 2 The components of an imaging and control system 12 connected to an endoscope 14, which in the illustrated example includes a duodenoscope, are schematically shown. The imaging and control system 12 may include a control unit 16, a treatment generator 44 and a drive unit 46, a light source unit 22, an input unit 20, and an output unit 18. The control unit 16 may include or be connected to an image processing unit 42. A connector section 36 may be connected to the control unit 16 to connect the endoscope 14 to various features of the control unit 16, such as the image processing unit 42 and the treatment generator 44. In the example, the plug portion 48 of the connector section 36 may include a lead 49 for connecting to wiring within a socket 37, which may be connected to the light source unit 22, the image processing unit 42, and the treatment generator 44. In the example, port 40A may be used to insert another instrument or device, such as a sub-scope or auxiliary scope, into the endoscope 14. Such instruments and devices can be independently connected to control unit 16 via cable 47, or can extend directly from fluid source 24 and suction pump 26 without originating from control unit 16. In this example, port 40B can be used to connect connector section 36 to various inputs and outputs such as video, air, light, and electricity. Control unit 16 can be configured to enable a camera device to view target tissue distal to endoscope 14. Similarly, control unit 16 can be configured to enable light source unit 22 to direct light to endoscope 14 or other devices extending therefrom. Light source unit 22 may include a light generator, such as a xenon lamp or a light-emitting diode. In this example, light source unit 22 may include multiple light generators to produce light with different characteristics, such as different colors.

[0037] The image processing unit 42 and the light source unit 22 can each be coupled to the endoscope 14 via a wired electrical connection or a wireless connection (e.g., at functional section 30). The imaging and control system 12 can thus illuminate the anatomical region, collect signals representing the anatomical region, process signals representing the anatomical region, and display an image representing the anatomical region on the display unit 18. The imaging and control system 12 may include the light source unit 22 to illuminate the anatomical region using light having a desired spectrum (e.g., broadband white light, narrowband imaging using a preferred electromagnetic wavelength, etc.). The imaging and control system 12 can (e.g., via an endoscope connector or socket 37) Figure 1 Connected to endoscope 14 for signal transmission (e.g., light output from a light source, video signals from an imaging system in the distal end, diagnostic and sensor signals from a diagnostic device, etc.).

[0038] Fluid source 24 ( Figure 1 The imaging and control system 12 may communicate with control unit 16 and may include one or more air sources, saline sources, or other fluid sources, as well as associated fluid pathways (e.g., air passages, flushing passages, suction passages) and connectors (barbed fittings, fluid seals, valves, etc.). Fluid source 24 may be used as activation energy for the biasing or pressure application devices of this disclosure. The imaging and control system 12 may also include a drive unit 46, which may be an optional component. Drive unit 46 may include a motorized actuator for advancing the distal segment of endoscope 14, as described at least in PCT Publication No. WO 2011 / 140118 A1, entitled “Rotate-to-Advance Catheterization System,” the entire contents of which are incorporated herein by reference.

[0039] As described above, the connector section 36 can be used to connect the endoscope 14 to the imaging and control system 12. The connector section 36 can be used to transmit various functions between the endoscope 14 and the imaging and control system 12. In examples, the connector section 36 can transmit communication signals, electronic signals, electrical signals, power signals, fluids including water and air, light waves, etc. The connector section 36 may include a portion of the endoscope 14 and can be configured for a specific configuration of the imaging and control system 12. For example, the connector section 36 can be configured to transmit light generated by the light source unit 22 to the endoscope 14 using a light conductor 39, as shown in the reference. Figure 3 As discussed herein, a light processing adapter can be connected to an imaging and control system 12 to be coupled to an endoscope having a built-in or onboard light generator. This light processing adapter can convert the light generated by the light source unit 22 into electronic commands for operating the onboard light generator to reproduce the light generated by the light source unit 22, as referenced. Figure 4 The subject of discussion.

[0040] Figure 3 This is a block diagram illustrating the optical connector 100 that connects the imaging and control system 102 to the endoscope 104. The imaging and control system 102 may include... Figure 1 and Figure 2 An example of an imaging and control system 12. The imaging and control system 102 may include a controller 105, a video processor 106, a memory 108, a light source 110, and a filter 112. In this example, the controller 105 may include... Figure 2 In an example of control unit 16, light source 110 may include Figure 2 An instance of the light source unit 22, and the video processor 106 may include Figure 2An example of an image processing unit 42. Endoscope 104 may include an endoscope cable 114, an endoscope handle 116, an endoscope working axis 118, an imaging device 120, a lens 122, and a light guide 124. In this example, the endoscope cable 114 may include... Figure 2 In an example of cable segment 34, the mirror handle 116 may include Figure 2 An example of the handle section 32, and the mirror working axis 118 may include Figure 2 An example of the insertion segment 28. In this example, the optical connector 100 may include... Figure 1 An example of socket 37. Therefore, mirror cable 114 may include something similar to Figure 1 The connector section 36 is the connector.

[0041] The optical fiber connector 100 can be used to transmit electrical signals and light waves between the imaging and control system 102 and the endoscope 104. Figure 3 In this diagram, light waves can be represented by dashed lines, and wired signals can be represented by solid lines. The optical fiber connector 100 can transmit electrical signals generated by the imaging device 120 to the imaging and control system 102, and transmit control signals from the controller 105 to the endoscope 104. For example, control signals for operating various features of the endoscope 104, such as ablation, suturing, RF signal generation, and cryogenic features, can be transmitted from the controller 105 to the endoscope 104. Furthermore, light waves from the light source 110 can be transmitted to the endoscope 104 via the optical fiber connector 100.

[0042] The optical connector 100 may include an optical conductor 126 and a power wiring 128. The endoscope 103 may include an optical conductor 130 and a power wiring 132. The imaging and control system 102 may include an optical conductor 134 and a control wiring 136. The optical conductor 126 of the optical connector 100 can connect the optical conductor 130 of the endoscope 104 to the light source 110 via the optical conductor 134, and the power wiring 128 of the optical connector 100 can connect the power wiring 132 of the endoscope 104 to the controller 105 via the control wiring 136.

[0043] Endoscope 104 can control the transmission of electronic imaging signals from imaging device 120 to imaging and control system 102. For example, light can enter lens 122 at endoscope 104. The light can be received by imaging device 120. In an example, imaging device 120 may include a charge-coupled device (CCD) or a solid-state device, such as complementary metal-oxide-semiconductor (CMOS). Imaging device 120 can convert the light waves received from lens 122 into electrical signals. The electrical signals can pass through suitable conductors of power wiring 132 through mirror working axis 118, mirror handle 116, and mirror cable 114 to power wiring 128 of light guide connector 100. Power wiring 128 of light guide connector 100 may include suitable connectors for transmitting electrical signals from imaging device 120 to imaging and control system 102 via control wiring 136. Therefore, video processor 106 can receive electrical signals from imaging device 120 for display on a video monitor, such as after appropriate processing. Figure 1 The output unit 18 is used for this purpose. The memory 108 may include various red, green, and blue image memories for processing signals generated by the imaging device 120.

[0044] In addition to optical and imaging signals, the optical connector 100 can also transmit other types of data, such as control signals for various functions of the endoscope 104. Specifically, control wiring 136, power wiring 128, and power wiring 132 can be additionally used to transmit control signals for the diagnostic and therapeutic functions of the endoscope 104. For example, the user can use, for example, input unit 20 (… Figure 2 The settings for the functions of the endoscope 104 are entered in the controller 105. The controller 105 can then generate appropriate control signals for transmission to the light guide connector 100. The power wiring 128 can be configured to utilize additional conductors or, for example, lead 49. Figure 2 The same conductor that transmits imaging signals is used to transmit control signals.

[0045] Furthermore, despite Figure 3 Not shown, but the optical connector 100 may include suitable tubes or conduits to deliver fluids such as saline, flushing fluid, air, blow-in gas and other gases to and from the endoscope 104.

[0046] The light source 110 can control the intensity and type of light generated by the imaging and control system 102. For example, characteristics of the light source 110 or the imaging and control system 102, such as the input unit 20 ( Figure 1The imaging and control system 102 may include control features such as buttons or knobs for starting and stopping light wave generation, controlling light wave intensity, etc. The imaging and control system 102 may additionally include control features for enabling or disabling different types of filters in the filter 112, such as color filters. Therefore, the user of the imaging and control system 102 can initiate settings for the light to be transmitted to the light guide 124 of the endoscope 104 at the imaging and control system 102. Typical user settings include: 1) on / off, 2) light intensity, and 3) light color. In the example, 1) the on / off setting may be a function of intensity (e.g., zero intensity equals off), 2) the intensity setting may be a function of the current or electrical signal supplied to the light source 110, and 3) the color setting may be a function of which filter 112 is applied to the output of the light source 110. Each of 1), 2), and 3) can be set by the user at the controller 105 and can be represented as characteristics of the light waves emitted from the light source 110. The optical conductor 126 of the optical connector 100 may include suitable connectors, conductors, or conduits for transmitting light waves from the optical conductor 134 of the light source 110 to the optical guide 124. Therefore, light waves from the light source 110 can pass through the filter 112, the optical conductor 134 of the imaging and control system 12, the optical conductor 126 of the optical connector 100, and the optical conductor 130 of the endoscope 104 (including...). Figure 2 The light conductor 39) and the light guide 124 travel, so that the light waves can leave the endoscope 14 to illuminate the anatomical structures in which the endoscope 104 is inserted.

[0047] With this configuration, the light guide connector 100 can be configured to transmit signals and light waves between the imaging and control system 102 and the endoscope 104 without modification. In this example, the endoscope 104 can be specifically configured to operate in conjunction with the imaging and control system 102. For example, the light guide 124 can be configured to transmit light waves generated by the light source 110 without interruption or introducing any distortion, such as color shift or intensity variation. Furthermore, the light guide connector 100 can provide electronic communication paths between the imaging device 120 and the video processor 106, and between the controller 105 and the functional components of the endoscope 104. Therefore, the light guide connector 100 does not include any capability for interpreting, analyzing, or altering the light signals, imaging signals, and control signals. Additionally, the light guide connector 100 can be mechanically configured to connect to a specific type of endoscope plug, such as… Figure 1 The connector section 36. Therefore, other types of endoscopes that are not configured to receive the output of the imaging and control system 12 or that are not mechanically configured to mate with the socket 37 are not interoperable or compatible with the imaging and control system 12.

[0049] The imaging and control system 102 may include a controller 105, a video processor 106, a memory 108, a light source 110, and a filter 112. The imaging and control system 102 may be as described in reference... Figure 3 The configuration is similar to that described, to provide light output at the optical conductor 134 and to send and receive communication signals via control wiring 136.

[0050] Endoscope 152 may include an endoscope cable 154, an endoscope handle 156, an endoscope working shaft 158, an imaging device 160, a lens 162, a light guide 164, and a light generator 166. Endoscope 152 can be used with... Figure 3 The endoscope 104 is constructed similarly, except that the endoscope 152 may include a light generator 166, instead of having a light conductor 130 extending through it like the endoscope 104. In this example, the endoscope cable 154 may be connected to... Figure 2 The cable section 34 is constructed similarly, and the mirror handle 156 can be connected to... Figure 2 The handle section 32 is constructed similarly, and the mirror working axis 158 can be coupled with... Figure 2 The insertion segment 28 is similarly constructed, including the imaging device 160 but not the optical conductor at its proximal end. In the example, the optical connector 100 may include... Figure 1 An example of socket 37.

[0051] Adapter 150 can be used to transmit information from optical connector 100 to endoscope 152. Adapter 150 can be configured to be inserted into socket 37. Figure 1 In the imaging and control system 102, light from the light source unit 22 and control signals from the control unit 16, as well as various air sources, are received. The optical fiber connector 100 can be used to transmit electrical signals and light waves between the imaging and control system 102 and the adapter 150. Figure 4 In this diagram, light waves can be represented by dashed lines, and wired signals can be represented by solid lines. Adapter 150 can transmit electrical signals generated by imaging device 120 to light guide connector 100 for transmission to imaging and control system 102. Adapter 150 can also transmit electrical signals from controller 105 and light guide connector 100 to endoscope 152. Adapter 150 can receive light waves generated by light source 110 from light guide connector 100 and can convert these light waves into combined signal wiring 170 for transmission to light generator 166. Light generator 166 may include a light source configured to output light waves. In one example, light generator 166 may include a light-emitting diode (LED). In another example, light generator 166 may be configured to produce light of different colors.

[0052] Adapter 150 may include a combination signal cabling 170 that extends through endoscope 152. The combination signal cabling 170 may branch into optical signal cabling 170A for communication with light generator 166 and imaging signal cabling 170B for communication with imaging device 160. Imaging and control system 102 may include optical conductor 134 and control cabling 136. Optical conductor 126 and power cabling 128 of optical connector 100 may be connected to adapter 150, and adapter 150 may transmit the combination signal cabling 170 to light generator 166 and imaging device 160.

[0053] Endoscope 152 can control the transmission of electronic imaging signals from imaging device 120 to imaging and control system 102. For example, light can enter lens 162 at endoscope 152. The light can be received by imaging device 160. In an example, imaging device 160 may include a charge-coupled device (CCD) or a solid-state device, such as complementary metal-oxide-semiconductor (CMOS). Imaging device 160 can convert the light waves received from lens 162 into electrical signals. The electrical signals can be transmitted via suitable conductors of combined signal wiring 170 through mirror working axis 158, mirror handle 156, and mirror cable 154 to power wiring 128 of light guide connector 100. Power wiring 128 of light guide connector 100 may include suitable connectors for transmitting electrical signals from adapter 150 to imaging and control system 102 via control wiring 136. Therefore, video processor 106 can receive electrical signals from imaging device 160 for display on a video monitor, such as an imager, after appropriate filtering, etc. Figure 1 On the output unit 18.

[0054] As described above, the light source 110 can control the intensity and type of light generated by the imaging and control system 102. For example, features of the light source 110 or the imaging and control system 102, such as the input unit 20 ( Figure 1 The light source 110 may include control features such as buttons or knobs for starting and stopping the generation of light waves, controlling the intensity of light waves, etc., to control 1) the on / off state of the light source 110, 2) the intensity of the light from the light source 110, and 3) the color of the light determined by the filter 112. The light conductor 126 of the light guide connector 100 may include suitable connectors, conductors, or conduits for transmitting light waves from the light conductor 134 of the light source 110 to the adapter 150. The adapter 150 may receive light waves from the light conductor 134 and convert the sensed characteristics of the light waves, such as on / off state, intensity, and color, into electronic control signals for the light generator 166. The adapter 150 may include suitable sensors and circuitry to convert light waves into electronic control signals, as shown in reference [reference needed]. Figures 5 to 15As discussed, light waves from light source 110 can travel through filter 112 and optical conductor 126 of optical connector 100 to adapter 150. Adapter 150 then transmits a light generation signal along combined signal wiring 170 to light generator 166, which can then output light to optical guide 164, thereby allowing the light waves to exit endoscope 152 to illuminate the anatomical structures in which endoscope 152 is inserted. Therefore, when the operator of imaging and control system 102 requests illumination, such as instructing light source 110 to turn on, light generator 166 can be commanded to generate light waves of equivalent intensity and color to the light waves exiting light source 110.

[0055] With this configuration, adapter 150 can be configured to transmit signals between imaging and control system 102 and endoscope 152 via translation, modification, or interpolation. Endoscope 152 does not need to be specifically designed to operate with imaging and control system 102 and can include any type of light generator 166 and connector section. In this example, endoscope 152 can be adapted to operate with imaging and control system 102 using adapter 150. Adapter 150 can provide a suitable mechanical interface between endoscope 152 and imaging and control system 102 and appropriately translate control inputs for 1), 2), and 3) input at controller 105 to light generator 166. In addition to optical signals such as light waves and imaging signals such as electronic communication signals, adapter 150 can transmit other types of data, such as control signals, and various fluids such as water and air, between optical connector 100 and endoscope 152. Adapter 150 can include reusable parts that are easy to clean and sterilize, while endoscope 152 can be constructed as a disposable endoscope that does not require cleaning or sterilization.

[0056] Figure 5 This is a rear perspective view of the adapter 200 disclosed herein, showing the main housing 202 and the plug component 204. Figure 6 yes Figure 5 A front perspective view of the adapter 200 shows a socket component 206 for receiving an endoscope plug. The adapter 200 may include... Figure 4 An instance of adapter 150. Also for... Figure 5 and Figure 6 Let's have a discussion.

[0057] The plug component 204 may include an air connector 208, a light conductor assembly 210, and an electrical lead 212. The air connector 208 and the light conductor assembly 210 may extend from an end face 214 of the plug component 204. The electrical lead 212 may extend from a shoulder or corner of the plug component 204. The air connector 208 and the light conductor assembly 210 can be coupled to the light guide connector 100. Figure 3 ) or directly connected to the light source unit 22 ( Figure 1 ) or another component of the imaging and control system 12. The plug component 204 can be inserted into the receiving portion 216 of the main housing 202. The main housing 202 can include lugs 218A and 218B, which can be coupled to a receiving portion, such as the receptacle 37 in the light guide connector 100 or the light source unit 22, via a twist lock or push-pull operation( Figure 1 ). The main housing 202 can include other features, such as pads 220A and 220B, for providing ergonomic engagement with a user's fingers.

[0058] The adapter 200 can be configured to receive light waves at the light conductor assembly 210, receive air at the air coupler 208, and receive control signals at the electrical leads 212 and 214. In an example, the plug component 204 can be constructed similarly to the plug portion 48 of the coupler section 36( Figure 2 ), and the electrical lead 212 can operate similarly to the lead 49. Therefore, control signals generated by the imaging and control system 12( Figure 1 and Figure 2 ) can be transmitted to the adapter 200. The light conductor assembly 210 can be constructed similarly to the light conductor 39( Figure 2 ). Accordingly, light output by the light source unit 22 can be transmitted to the adapter 200.

[0059] The receptacle component 206 can include an opening 222 to receive an endoscope plug, such as the plug connected to the combined signal wiring 170( Figure 4 ). The opening 222 can include an air coupler 230 for communicating with the endoscope 152( Figure 4 )( Figure 8 ) and an electrical coupler 232( Figure 8 ). As discussed with reference to Figure 7 and Figure 8 , the adapter 200 can allow air and control signals to pass through the main housing 202 and the plug component 204 via the fluid coupler 230 and the electrical coupler 232.

[0060] Figure 7 is Figure 5 and Figure 6 a rear view of the adapter 200, showing the light conductor assembly 210 and the air coupler 208. Figure 8 is Figure 5 and Figure 6 a front view of the adapter 200, showing the air coupler 230, the electrical coupler 232, and alignment posts 234A and 234B. A simultaneous discussion of Figure 7 and Figure 8 is provided.

[0061] The plug component 204 can be inserted into the socket 37 of the light source unit 22. Figure 1 When inserted, electrical leads 212 and 214 can be connected to electrical contacts within socket 37 to allow the transmission of electrical signals from imaging and control system 12, such as those from control unit 16 and light source unit 22.

[0062] For use in endoscope 152 ( Figure 4 The socket of the adapter 200 can be inserted into the opening 222. The opening 222 can have an irregular shape, such as a roughly square shape with one side rounded, to facilitate assembly with the endoscope plug in one orientation. Alignment posts 234A and 234B can be located in the opening 222 to facilitate engagement with the endoscope plug. For example, alignment posts 234A and 234B can include cylindrical posts on which the cylindrical socket in the endoscope plug can slide for alignment. In addition, alignment posts 234A and 234B can relieve stress applied to the fluid connector 230 and the electrical connector 232. In another example, alignment posts 234A and 234B can be spring-loaded to facilitate the ejection of the adapter 200. For example, alignment posts 234A and 234B can be biased to an extended position and then compressed when the adapter 200 is connected to the control unit. Thus, the force of the compressed spring can facilitate the ejection of the adapter 200 when pulled by an operator or user.

[0063] Air lines can be connected to air connectors 208 and 230. Air line 242 ( Figure 10 and Figure 11 An air connector 208 and an air connector 230 may extend between the air connector 208 and the air connector 230 to allow air to pass through the adapter 200. For example, air connectors 208 and 230 may be connected to air, carbon dioxide, brine, water, and other fluids to perform various functions, including blow-in. In examples, air connectors 208 and 230 may include hose connectors or hose fittings with and without valves. In examples, the adapter 200 may be configured to simply allow air to pass through the main housing 202 and the plug assembly 204 without interference, regulation, or control. However, in some examples, the adapter 200 may be configured based on a control unit 16 (… Figure 1 Electrical signals received from other sources, such as through electronically controlled valves, can be used to actively control the airflow through the main housing 202 and the plug component 204.

[0064] The light conductor assembly 210 can be configured to receive light waves from a light source. Specifically, the end of the light conductor assembly 210 can face the output end of a bulb or LED within the light source unit 22. The light conductor assembly 210 can extend into the plug member 204 and release light waves onto the sensor package 245. Figure 9As discussed in more detail below, the electronics connected to the sensor package 245 can convert light waves into light for use in the light generator 166. Figure 4 The instructions can be transmitted via electrical connector 232. In the example, the optical conductor assembly 210 may include an optical conductor 240 disposed in the sheath 241. In the example, the optical conductor 240 may include an optical conduit or fiber bundle. For example, the optical conductor 39 of the endoscope 14 ( Figure 2 The optical conductor 39 may include a bundle of optical fibers, as it may include the nearest end of the bundle of optical fibers extending through the cable segment 34 and the insertion segment 28. Therefore, it is desirable to produce the optical conductor 39 with multiple optical fibers to increase flexibility. However, the optical conductor 240 may include an optical conduit that may include a single optical conductor with a diameter much larger than that of a single optical fiber. Therefore, the optical conductor 240 may be rigid and more robust, for example, more heat-resistant. (See reference...) Figure 13 Further description of the photoconductor assembly 210 is provided.

[0065] Figure 9 yes Figure 5 and Figure 6 A front perspective view of the adapter 200, wherein the main housing 202 is removed to show the support bracket 203 connected to the plug component 204 and the socket component 206. Figure 9 Sensor package 245 is also shown. Figure 10 yes Figure 9 A front perspective view of the adapter 200, with the support bracket 203 and socket component 206 removed to show the air connector 230, electrical connector 232, optical conductor 240, and air conduit 242. Meanwhile, for... Figure 9 and Figure 10 Let's have a discussion.

[0066] Optical conductor 240 can be connected to optical conductor assembly 210 extending from plug component 204. The optical conductor can guide light to sensor package 245. Air conduit 242 can be connected to air connector 230 and air connector 208. Figure 5 and Figure 7 The light board 244 can be connected to the control board 246 of the plug component 204 via fasteners 248 and posts 250. The control board 246 can be connected to pins 254 of the electrical lead 212. The control board 246 can be connected to the communication board 252 via connector 253, which can be mounted on board 255. Connector 253 can be connected via wiring 256 (…). Figure 11 The optical board 244 can be connected to the communication board 252 via wiring 258. Figure 11 The endoscope 152 is connected to the communication board 252. The communication board 252 can be connected to the electrical connector 232 for transmitting control signals and light generation signals to the endoscope 152. Figure 4Therefore, when the plug component 204 is inserted into the socket 37 ( Figure 1 When the endoscope is inserted into the socket 37, the electrical lead 212 can be configured to communicate with the endoscope 152 via pin 254, communication board 252, and electrical connector 232. Similarly, when the plug component 204 is inserted into the socket 37, the air conduit 242 can be configured to communicate with the endoscope 152 via air conduit 242, air connector 208, and air connector 230. Furthermore, the photoconductor assembly 210 can be aligned with the sensor package 245.

[0067] Figure 11 Is it through Figure 10 A cross-sectional view of the adapter 200, showing an air conduit 242 passing through the adapter 200 and a sensor package 245 positioned near the photoconductor 240.

[0068] Air conduit 242 may include a conduit connecting to air connectors 208 and 230. In an example, air conduit 242 may include a rubber or plastic pipe or tube. Air conduit 242 may connect to suitable fittings on air connectors 208 and 230 to provide a leak-proof passage through adapter 200. For example, air connectors 208 and 230 may include barbed fittings on which air conduit 242 may be fitted. Air connector 208 may include a convex protrusion that can be fitted to socket 37. Figure 1 The air connector 230 may include a concave receiving portion that can receive the mirror cable 154. Figure 4 The air connector 208 may be rigidly supported by the end face 214 of the plug member 204, and the air connector 230 may be rigidly supported by the socket member 206. The air line 242 may extend unsupported through the adapter 200 between the air connectors 208 and 230. Therefore, the support bracket 203 and the control plate 246 may include suitable openings to allow the air line 242 to extend through them.

[0069] Figure 12 Is it through Figure 10 A cross-sectional view of the adapter 200 shows the optical conductor 240 for mounting to the sensor package 245 connected to the optical plate 244 via the electrical connector 232. See also... Figure 11 Let's discuss Figure 12 .

[0070] The photoconductor assembly 210 can be attached to the receptacle component 206. Specifically, the sheath 241 can be inserted into the reception portion 259 in the end face 214 of the receptacle component 206. The distal end of the photoconductor 240 can protrude through the photoconductor plate 244 and the support bracket 203 to be located near the sensor package 245 within the main housing 202. The photoconductor plate 244 can be mounted to the support bracket 203 via fasteners 248. The photoconductor plate 244 can be positioned to communicate with the communication board 252 via suitable connectors. In one example, wiring 258 can connect the photoconductor plate 244 and the communication board 252. In other examples, the photoconductor plate 244 can be connected to a control board 246. In one example, a post 250 can be connected to the support bracket 203 to provide alignment. Thus, the output of the sensor package 245 can be shared with other electrical components of the adapter 200. See reference... Figure 14 The sensor package 245 discussed may include one or more optical sensors for interpreting various characteristics of light waves emitted from the optical conductor 240. The sensor package 245 or other suitable electronic equipment may convert the output of the optical sensors into signals for operating the light generator 66. Figure 4 Instructions for operating the light generator 66 can be transmitted to the electrical connector 232 along with other control signals from the electrical leads 212. In this example, the electrical connector 232 may include input / output devices configured to send and receive electronic communication signals and electrical signals, such as current. In this example, the electrical connector 232 may include a Universal Serial Bus (USB) port, particularly a USB-C port. Therefore, outputs from the sensor package 245 and various pins 254, and from the control unit 16, can be transmitted to various components of the endoscope 152. Figure 4 ).

[0071] Figure 13 Is it through Figure 10 The cross-sectional view of the adapter 200 shows the light conductor assembly 210. The light conductor assembly 210 may include a light conductor 240, a sheath 241, an end cap 260, a lens 262, a first filter 264A, a second filter 264B, a first seal 266A, and a second seal 266B.

[0072] The proximal end of the photoconductor 240 may include a face 268. Face 268 may be positioned to receive the output from the outlet 37 generated by the light source unit 22. Figure 1The light wave is emitted from the sensor package 245. The light conductor 240 may extend distally toward the sensor package 245. A sheath 241 may surround the proximal portion for assembly with the plug component 204. Filters 264A and 264B may be positioned close to surface 268 to receive light entering the light conductor 240. Filters 264A and 264B may include polarizing films angled relative to each other to reduce the intensity of light transmitted to the light conductor 240. In this example, as a safety feature, the intensity of light entering the light conductor 240 may be reduced to limit the temperature of the light reaching the sensor package 245. Furthermore, very high light intensities could potentially electronically overwhelm the sensor within the sensor package 245. The sensor package 245 may be configured to have a memory storing information about the amount of intensity reduction provided by filters 264A and 264B, allowing for corresponding adjustments to the operation of the light generator 166. Figure 4 The instructions are as follows. (Refer to...) Figure 14 and Figure 15 Further discussion of the operation of sensor package 245 is provided.

[0073] End cap 260 may be disposed around filters 264A and 264B to secure filters 264A and 264B to surface 268 of optical conductor 240. End cap 260 may include lens 262 and fitting 270. Fitting 270 may include retaining means to hold filters 264A and 264B on optical conductor 240. End cap 260 may then be positioned on fitting 270 to hold filters 264A and 264B in place. Lens 262 may include glass or crystal to allow light waves to pass through without variation. Lens 262 may protect filters 264A and 264B.

[0074] Figure 14 This is a block diagram illustrating the optical processing adapter 300 of this disclosure. The optical processing adapter 300 may include a housing 302, an optical channel assembly 304, a first input / output (I / O) device 306, a second input / output (I / O) device 308, an air channel 310, and a controller 312. The controller 312 may include a circuit board 314, a processor 316, and a memory 318. The optical channel assembly 304 may include a filter 320, an optical channel 322, a first sensor 324A, and a second sensor 324B.

[0075] Air channel 310 can be constructed similarly to air connector 208, air line 242, and air connector 230. Air channel 310 can be constructed as a pipe or tube to allow fluids such as air, gas, and water to pass through adapter 300. The ends of air channel 310 can be provided with suitable convex or concave fittings for connection to the imaging control system and endoscope.

[0076] I / O device 306 can be configured as electrical leads 212, pins 254, and a control board 246, or communicate with electrical leads 212, pins 254, and a control board 246. I / O device 306 can be configured to transmit electronic communication signals into and out of adapter 300 for communication with imaging and control systems. I / O device 308 can be configured as an electrical connector 232. I / O device 306 can be configured to transmit electronic communication signals into and out of adapter 300 for communication with a light-generating endoscope.

[0077] In the example, I / O devices 306 and 308 can communicate using wireless communication signals such as Bluetooth, WiFi, Zigbee, infrared (IR), near-field communication (NFC), 3GPP, or other technologies. In the example, I / O devices 306 and 308 can include wired connections or ports for receiving wiring for wired connections. In the example, I / O devices 306 and 308 can communicate using one or more of the IEEE 802.15.6-2012 protocol, the MICS protocol, and the MBAN protocol. In the example, I / O devices 306 and 308 can include ports, such as serial (e.g., a Universal Serial Bus (USB) port, a parallel port, or other wired or wireless (e.g., infrared (IR), near-field communication (NFC), etc.)) connections, for communicating or controlling imaging and control systems and one or more features of the endoscope.

[0078] Filter 320 can be configured as filters 264A and 264B. In one example, filter 320 may include an absorption filter that absorbs wavelengths of certain colors while allowing wavelengths of other colors to pass through. In another example, filter 320 may include an interference filter that reflects wavelengths in certain spectral bands while transmitting wavelengths in other spectral bands. In yet another example, filter 320 may include a pair of polarizing filters that are rotated and offset to allow light waves of a specific polarization to pass through while blocking light waves of other polarizations.

[0079] The optical conduit 322 can be configured as an optical conductor 240. The optical conduit 322 may comprise a single or integral component made of optical acrylic or polycarbonate or other materials. In alternative examples, the optical conduit 322 may be replaced by a bundle of optical fibers made of silica or plastic or other materials. The optical conduit 322 may extend between the filter 320 and sensors 324A and 324B. Therefore, light exiting the filter 320 can enter one end face of the optical conduit 322, and light exiting the opposite end face of the optical conduit 322 can be guided to sensors 324A and 324B.

[0080] The first sensor 324A and the second sensor 324B can be configured as part of the sensor package 245. Figure 11 and Figure 12 In the example, the first sensor 324A may include a light intensity sensor. In the example, the first sensor 324A may include a photodiode, a photoresistor, a phototransistor, and a photovoltaic light sensor. In the example, the second sensor 324B may include a color sensor. In the example, the second sensor 324B may include a light-to-photocurrent conversion sensor, a light-to-analog voltage conversion sensor, and a light-to-digital conversion sensor.

[0081] Circuit board 314 may include structural components for electrically and structurally connecting electrical components of adapter 300. For example, circuit board 314 may include a silicon wafer or chip with electrical connections attached for electrical connections to processor 316, memory 318, sensor 324A, and sensor 324B, etc. Circuit board 314 connected to processor 316, memory 318, and sensors 324A and 324B can operate as a converter for converting light waves into electrical signals as described herein.

[0082] Processor 316 may include an integrated circuit that controls the operation of components of adapter 300, such as I / O devices 306 and 308, sensors 324A and 324B, and memory 318. Processor 316 can execute instructions stored in memory 318 to operate components of adapter 300, such as sensors 324A and 324B. In this example, no processor or memory is required, and adapter 300 can operate as a simple integrated circuit, whereby the outputs of sensors 324A and 324B can be directly transmitted by I / O devices 306 and 308.

[0083] Memory 318 may include any suitable storage device, such as non-volatile computer-readable memory, magnetic storage, flash memory, volatile memory, programmable read-only memory, etc. Memory 318 may include instructions stored therein for operating the processor 316 to control the adapter 300. For example, memory 318 may include instructions for operating I / O devices 306 and 308 and sensors 324A and 324B. Memory 318 may additionally include reference data for comparing with data from sensors 324A and 324B, such as comparing sensed light intensity with data input to light generator 166. Figure 4 A lookup table associated with the power and other information of the light source 110 can be used to convert light waves of a specific intensity and color into one or more electrical signals to produce light of the same or approximately the same intensity and color. In the example, memory 318 may include a lookup table having a range from zero to light source 110. Figure 4The maximum output light intensity of the light generator 166 is the same as the maximum input light intensity from zero to the maximum output light intensity of the light generator 166. Figure 4 It is associated with the current input.

[0084] In this example, memory 318 may include instructions for scaling the light signal generated by light generator 166 based on the effect of filter 320. For example, memory 318 may include an appropriate scaling factor to be applied to the lookup table discussed above. For instance, the processor may determine that filter 320 reduces the output of light source 110 by fifty percent, such that the outputs of sensors 324A and 324B can be increased by fifty percent before consulting to generate the appropriate current for operating light generator 166.

[0085] In another example, memory 318 may include instructions that allow processor 316 to compensate for light source 110. For example, it is well known that various light sources, such as xenon lamps, dim over time, emitting less light than desired. Therefore, an imaging and control system requiring a specific light intensity output may cause the light source to output light with, for example, 95% of the required intensity. The light processing adapter of this disclosure can be configured to compensate for this dimming. In an example, imaging and control system 102 can be configured to provide 0% and 100% light intensity output to light source 110 upon startup. Light processing adapter 300 can store appropriate, for example, expected undimmed output, 0% and 100% intensity output for a specific model of imaging and control system 102, in memory 318. Therefore, processor 316 can determine that light source 110 outputs only 95% of the output requested by imaging and control system 102, and can appropriately amplify the output of light generator 166 such that the output of light generator 166 matches the required light intensity at imaging and control system 102, even if light source 110 does not provide the required light intensity.

[0086] Figure 15 This is a block diagram illustrating the operation of a method 400 for converting light generated by an imaging and control system 12 into a light control signal for a light generator 166 of an endoscope 152.

[0087] At operation 402, light can be generated using a first light generator of the imaging and control system. For example, light can be generated using the imaging and control system 102 ( Figure 4 The light source 110 generates light. The user can input on / off, intensity, and color settings on the user interface. For example, the user can utilize the output unit 18 and the input unit 20 (…). Figure 1 Use this option to input the on / off state, intensity, and color settings for the light source 110.

[0088] At operation 404, it can be connected to the imaging and control system 102 ( Figure 4The adapter 300 receives light from a first light generator, such as light source 110. Light waves from light source 110 can enter the light conductor assembly 210 of the adapter 300. When the adapter 300 is plugged into socket 37... Figure 1 When the light conductor assembly 210 is positioned opposite to the bulb or light-emitting diode in the light source 110, the light conductor assembly 210 can be positioned opposite to the light bulb or light-emitting diode in the light source 110.

[0089] At operation 406, the light-sensing characteristics of the sensor at the adapter can be utilized. For example, the first sensor 324A ( Figure 14 This can be used to sense the intensity of light from light source 110. Furthermore, in this example, the second sensor 324B ( Figure 14 This can be used to sense the color of light from light source 110. The light wave can exit the photoconductor assembly 210 and be incident on the first sensor 324A and the second sensor 324B of the sensor package 245. The light wave can energize appropriate elements of the first sensor 324A and the second sensor 324B to generate an electrical signal.

[0090] At operation 408, the light characteristics sensed by the sensor can be converted into a control signal for generating light using a second light generator of the endoscope. For example, the light intensity sensed by the first sensor 324A can be converted into a control signal for generating light using the endoscope 152 ( Figure 4 ) light generator 166 ( Figure 4 The instruction to generate light of the same intensity. Furthermore, in this example, the color of light sensed by the second sensor 324B can be converted into an instruction to generate light of the same color using the light generator 166.

[0091] In the example, processor 316 can receive a signal from first sensor 324A relating to the light intensity from light source 110. The light intensity from light source 110 can be linearly related to the current input to light source 110. Therefore, the current output from first sensor 324A can be scaled by processor 316 as a control signal for light generator 166. Processor 316 can consult a lookup table stored in memory 318 containing the output value of first sensor 324A associated with the current value to be supplied to light generator 166 to generate an equivalent light intensity output by light source 110. Memory 318 can be configured with lookup tables for different combinations of light source 110 and light generator 166. In the example, processor 316 can receive signals from imaging and control system 12—which provides identification of light source 110, such as manufacturer, light type, bulb type, color type, LED type, etc.—and from endoscope 152 ( Figure 4The processor 316 provides an identification signal that identifies the light generator 166, such as manufacturer, light type, bulb type, color type, LET type, etc. Therefore, the processor 316 can consult a lookup table with appropriate information to convert the light output of the determined imaging and control system into a control input for the determined light generator 166. Furthermore, as discussed herein, the processor 316 can adjust the outputs of sensors 324A and 324 to accommodate light intensity filtering performed within the adapter 300 using filter 320, and to provide light intensity compensation for dimming of the output of the light source 110 due to prolonged use.

[0092] At operation 410, the light control signal can be transmitted via an adapter to the second light generator of the endoscope. For example, the light control signal generated by processor 316 can be transmitted via combination signal wiring 170 and light signal wiring 170A to the light generator 166 of endoscope 152. Light generator 166 can generate light waves with an intensity based on the received output of adapter 300. Furthermore, light generator 166 can generate light waves of the desired color by adapter 300. Therefore, the light output of light generator 166 can be matched in intensity and color to the output of light source 110. Then, light generator 166 can release light waves, which can be emitted, for example, by using light guide 164 ( Figure 4 ) Irradiate onto the tissue.

[0093] As discussed herein, this disclosure is useful in providing light-generating instructions to disposable or reusable endoscopes having onboard light-generating capabilities, such as using an LED with a light processing adapter. The light processing adapter of this disclosure allows an endoscope with an onboard LED to receive light-generating instructions from an imaging and control system not configured to communicate with the endoscope's light generator. As discussed herein, the light processing adapter of this disclosure allows for the conversion and transmission of instructions input to the imaging and control system to the light-generating endoscope via the use of a light sensor within the adapter, through the generation of light waves at the imaging and control system. Therefore, light-generating endoscopes, such as disposable endoscopes, can be used with existing primary equipment, such as imaging and control systems.
