[0001] Priority claim 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 hereby incorporated by reference.

[0002] SUMMARY The present disclosure relates generally to medical devices that include an elongate body configured to be inserted into an incision or opening in a patient's anatomy to provide a diagnostic or treatment operation.

[0003] More particularly, the present disclosure relates to systems and devices for establishing connectivity between medical devices, imaging systems, and control systems. [Background technology]

[0004] Endoscopes can be used for one or more of: 1) providing passage of therapeutic or other devices, such as tissue retrieval devices, to various anatomical portions, such as the digestive tract (e.g., esophagus, stomach, duodenum, pancreatic bile duct, intestine, and colon), renal region (e.g., kidney, ureter, bladder, urethra), and other internal organs (e.g., reproductive system, sinus cavities, submucosal regions, airways).

[0005] Conventional endoscopes may be involved in a variety of clinical procedures, including, for example, illuminating, imaging, detecting, and diagnosing one or more disease states, providing fluid delivery (e.g., saline or other preparations via a fluid passageway) to an anatomical region, providing passage of one or more therapeutic devices (e.g., via a working passageway) to sample or treat an anatomical region, and providing aspiration passageways to withdraw fluids (e.g., saline or other preparations), etc.

[0006] In conventional endoscopes, the distal portion of the endoscope may be configured to support and orient a therapeutic device, such as with the use of an elevator. In some systems, two endoscopes may be configured to work together, with the first endoscope guiding the second endoscope, which is inserted with the aid of an elevator. Such systems may be useful when guiding an endoscope to difficult-to-reach anatomical locations within the body. For example, some anatomical locations can only be accessed endoscopically after insertion through a circuitous path. For example, a duodenoscope procedure (e.g., an endoscopic retrograde cholangiopancreatography, hereafter "ERCP" procedure) involves the use of an auxiliary scope (also called a dotascope or cholangioscope) that can be advanced through the working channel of the main scope (also called a motherscope or duodenoscope). Additionally, other devices, such as tissue retrieval devices used for biopsies, can be inserted into the auxiliary scope. Typically, the duodenoscope, auxiliary scope, and tissue retrieval device are configured in a telescoping arrangement, thereby becoming progressively smaller. Typically, after each use, duodenoscopes, auxiliary scopes, and tissue retrieval devices are cleaned and sterilized for reuse, and therefore, imaging and control systems, including light-generating devices, image processing capabilities, and treatment functions, are typically configured for repeated use with the same types of endoscopes and instruments.

[0008] [Non-Patent Document 1] International Electrotechnical Commission document IEC 62680-1-3:2022 Summary of the Invention [Problem to be solved by the invention]

[0009] The present disclosure recognizes that a problem solved in surgical systems involves the need to adapt a single-use endoscope for use with existing imaging and control systems. For example, there is a recent demand for utilizing single-use endoscopes to eliminate the need to clean, sterilize, and reprocess reusable scopes. However, much capital equipment, such as light-generating devices, image processing equipment, and treatment equipment, is configured for use with reusable endoscopes that have specific compatibility, such as compatibility of illumination and imaging systems. Specifically, many endoscopes include light transmission capabilities, such as a light conductor or light pipe, that transmit light generated in the imaging and control system to the distal end of the endoscope for use in the anatomy. This allows the operator of the endoscope to control the imaging and illumination characteristics of the endoscope from the imaging and control system. Therefore, there is a need to create a single-use endoscope that is compatible with both existing imaging and control systems and is inexpensive. [Means for solving the problem]

[0010] The present disclosure provides a solution to these and other problems by providing systems, devices, and methods related to an adapter that can transmit illumination commands from an imaging and control system to an endoscope, specifically to a single-use endoscope equipped with a light-generating device. It may be desirable to create a single-use endoscope that includes a light-generating device, such as a light-emitting diode (LED), instead of a light-transmitting device. LED light-generating devices can be less expensive than light-transmitting devices such as optical fibers. Furthermore, optical fibers can be delicate and prone to breakage if mishandled. 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 into the imaging and control system for a light-generating device in the imaging and control system would not alter the light generated by the light-generating device in the endoscope because electronic signals from the light-generating device in the imaging and control system would not be communicated to the endoscope. With the present disclosure, an endoscope adapter can be configured to provide illumination commands to a light-generating device in the endoscope based on illumination commands input into the imaging and control system. In an example, the adapter of the present disclosure can include one or more light sensors that convert light generated by the imaging and control system and passed to the adapter into instructions for a light-generating device in the endoscope. The one or more sensors can sense parameters of the light generated in the imaging and control system and convert the sensed parameters into instructions for a light-generating device in the endoscope to generate light having 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 with a light-generating device 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 with a light-generating device in the endoscope.This allows existing imaging and control systems, as well as associated operating procedures, to be used with endoscopes equipped with light-generating devices, including single-use endoscopes.

[0011] The present disclosure may provide a solution to these and other problems by providing systems, devices, and methods related to adapters that allow a single-use endoscope manufactured with a standardized computer connector to be used with an endoscopic system having a non-standardized connector, such as those specifically designed and manufactured for use with medical imaging systems, surgical systems, and endoscopic systems. As previously discussed, it is desirable to create a single-use endoscope that is compatible with both existing imaging and control systems and is inexpensive. Furthermore, different endoscopic system manufacturers may have different connector configurations for their respective imaging and control systems that may be incompatible with each other. Therefore, manufacturing single-use endoscopes with different endoscopic system connectors can be time-consuming. With the present disclosure, a single-use endoscope can be manufactured with a standardized connector, such as a USB (Universal Serial Bus), thereby simplifying the need to manufacture different replacement single-use endoscopes. The conversion adapter of the present disclosure may include a first standardized connector for connecting with a mating standardized connector of a single-use endoscope and a second non-standardized connector for connecting with a mating non-standardized connector of an endoscopic system. Thus, the conversion adapter can include an endoscopic system connector that can be used with a connector from a specific manufacturer of an endoscopic system, or that can be used with multiple endoscopic systems and single use endoscopes that have inexpensive, widely compatible connectors. In examples, the conversion adapters of the present disclosure can additionally provide other capabilities that enable the single use endoscope to be used with endoscopic systems, such as light processing capabilities.

[0012] In an example, an adapter for connecting an endoscope to a video processing device may include a housing extending between a first end portion and a second end portion, a first connector positioned at the first end portion, the first connector comprising a standardized computer peripheral connector, and a second connector positioned at the second end portion, the second connector comprising a non-standardized computer peripheral connector.

[0013] In another example, a method for communicating signals between an endoscope and an imaging system of an endoscopic system may include the steps of connecting the endoscope to a first connector of a conversion adapter, the first connector comprising a standardized computer peripheral connector; connecting the imaging system to a second connector of the conversion adapter, the second connector comprising a non-standardized computer peripheral connector; and transmitting communication signals from the imaging system to the endoscope through the first connector and the second connector.

DETAILED DESCRIPTION OF THE INVENTION

[0015] FIG. 1 is a schematic diagram of an endoscopic system 10 including an imaging and control system 12 and an endoscope 14. The system of FIG. 1 is an illustrative example of an endoscopic system suitable for use with the systems, devices, and methods described herein, such as a light processing adapter. According to some examples, the endoscope 14 may be insertable into an anatomical region for imaging and / or to provide for the passage of other devices, such as auxiliary scopes and biopsy devices, or one or more therapeutic devices for the treatment of a disease state associated with the anatomical region. The endoscope 14 may advantageously interface with and connect to the imaging and control system 12, such as via insertion of a coupler section 36 into a socket 37. In the illustrated example, the endoscope 14 comprises a duodenoscope, although other types of endoscopes may be used with the features and teachings of the present disclosure.

[0016] 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 .

[0017] The imaging and control system 12 may include various ports for coupling with the endoscope system 10. For example, the control unit 16 may include a data input / output port for receiving data from and communicating data to the endoscope 14. Such a data input / output port may be provided through an interface between the coupler section 36 and a socket 37. The light source unit 22 may include an output port for transmitting light to the endoscope 14, such as via a fiber optic link. For example, the coupler section 36 may include a photoconductor 39 ( FIG. 2 ) configured to receive light from a lens or bulb in the light source unit 22. The fluid source 24 may include a port for conveying fluid to the endoscope 14. The fluid source 24 may include a fluid pump and tank or may be connected to an external tank, container, or storage unit. The suction pump 26 may include a port used to draw a vacuum from the endoscope 14 to generate suction, such as to draw fluid from the anatomical region into which the endoscope 14 is inserted. In an example, a fluid such as air may be delivered to the endoscope 14 through an interface in the coupler section 36 and the socket 37. In an example, a fluid such as water may be input directly to the coupler section 36 without exiting the socket 37. An output unit 18, such as a touchscreen display, and an input unit 20, such as a keyboard, may be used by an operator of the endoscope system 10 to control functions of the endoscope system 10 and to view the output of the endoscope 14. The control unit 16 may additionally be used to generate signals or other outputs from treating the anatomical region into which the endoscope 14 is inserted. In an example, the control unit 16 may generate electrical outputs, acoustic outputs, fluid outputs, etc., to treat the anatomical region with cauterization, cutting, freezing, etc.

[0018] The endoscope 14 may include an insertion section 28, a function section 30, and a handle section 32 that may be coupled to a cable section 34 and a coupler section 36. The coupler section 36 may be connected to the control unit 16 at a socket 37 for connecting the endoscope 14 to 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 may be directly connected to the endoscope 14 without being routed through the control unit 16.

[0019] The insertion section 28 can extend distally from the handle section 32, and the cable section 34 can extend proximally from the handle section 32. The insertion section 28 can be elongated and can include a bending section and a distal end to which the functional section 30 can be attached. The bending section can be controllable (e.g., by a control knob 38 on the handle section 32) to maneuver the distal end through tortuous anatomical passageways (e.g., the stomach, duodenum, kidney, ureter, etc.). The insertion section 28 can be elongated and can include one or more working passageways (e.g., lumens) that can support insertion of one or more therapeutic tools of the functional section 30, such as an auxiliary scope. The working passageways can extend between the handle section 32 and the functional section 30. Additional functions, such as fluid passageways, guidewires, and puller wires, can be provided by the insertion section 28 (e.g., via aspiration or irrigation passageways, etc.).

[0020] Handle section 32 may include port 40A as well as control knob 38. Control knob 38 may be coupled to a pull wire or other actuation mechanism extending through insertion section 28. In addition to port 40A, other ports, such as port 40B (FIG. 2), may be configured to couple various electrical cables, guide wires, auxiliary scopes, tissue collection devices, fluid tubing, and the like to handle section 32 for coupling with insertion section 28.

[0021] An example imaging and control system 12 may be mounted on a mobile platform (e.g., cart 41) with shelves for housing light source unit 22, suction pump 26, image processing unit 42 (FIG. 2), etc. Alternatively, some components of imaging and control system 12 shown in FIGS. 1 and 2 may be mounted directly on endoscope 14, making the endoscope "self-contained."

[0022] Functional section 30 may include components for treating and diagnosing a patient's anatomy. Functional section 30 may include an imaging device, an illumination device (e.g., the distal end of an optical fiber), and an elevator. Typically, operation of some or all features of functional section 30 is implemented in imaging and control system 12.

[0023] FIG. 2 is a schematic diagram of the endoscopic system 10 of FIG. 1 , including an imaging and control system 12 and an endoscope 14. FIG. 2 schematically illustrates components of the imaging and control system 12 coupled to the endoscope 14, which in the illustrated example comprises a duodenoscope. The imaging and control system 12 may include a control unit 16, which may include or be coupled to a light source unit 22, an input unit 20, and an output unit 18, as well as an image processing unit 42, a treatment generator 44, and a drive unit 46. A coupler section 36 may be connected to the control unit 16 for connecting the endoscope 14 to multiple features of the control unit 16, such as the imaging and processing unit 42 and the treatment generator 44. In an example, a plug portion 48 of the coupler section 36 may include leads 49 for connecting to wiring in a socket 37, which may be connected to the light source unit 22, the image processing unit 42, and the treatment generator 44. In an example, the port 40A may be used to insert other instruments or devices, such as a dotoscope or an auxiliary scope, into the endoscope 14. Such instruments and devices can be independently connected to the control unit 16 via cable 47, or can extend directly from the fluid source 24 and suction pump 26 rather than coming from the control unit 16. In an example, port 40B can be used to connect the coupler section 36 to various inputs and outputs, such as video, air, light, and electricity. The control unit 16 can be configured to activate a camera to view target tissue distal to the endoscope 14. Similarly, the control unit 16 can be configured to activate the light source unit 22 to direct light to the endoscope 14 or other devices extending from the endoscope 14. The light source unit 22 can include a light-generating device, such as a xenon bulb or a light-emitting diode. In an example, the light source unit 22 can include multiple light-generating devices to generate light with different characteristics, such as different colors.

[0024] Each of the image processing unit 42 and the light source unit 22 can be interfaced with the endoscope 14 (e.g., at the function section 30) by a wired or wireless electrical connection. Thus, the imaging and control system 12 can illuminate the anatomical region, collect signals representative of the anatomical region, process the signals representative of the anatomical region, and display an image representative of the anatomical region on the output unit 18. The imaging and control system 12 can include the light source unit 22 to illuminate the anatomical region using a desired spectrum of light (e.g., broadband white light, narrowband light observation using a preferred electromagnetic wavelength, etc.). The imaging and control system 12 can be connected to the endoscope 14 (e.g., via an endoscope connector or socket 37 (FIG. 1)) for signal transmission (e.g., light output from the light source, video signals from the imaging system at the distal end, diagnostic and sensor signals from diagnostic devices, etc.).

[0025] The fluid source 24 (FIG. 1) can be in communication with the control unit 16 and can include one or more sources of air, saline, or other fluids, as well as associated fluid passages (e.g., air passages, irrigation passages, suction passages) and connectors (such as barb fittings, fluid seals, and valves). The fluid source 24 can be utilized as actuation energy for the biasing or pressure application devices of the present disclosure. The imaging and control system 12 can also include a drive unit 46, which can be an optional component. The drive unit 46 can include a motorized drive for advancing the distal section of the endoscope 14, as described at least in U.S. Patent No. 6,279,999 to Frassica et al., entitled "Rotate-to-Advance Catheterization System," which is hereby incorporated by reference in its entirety.

[0026] As previously described, the coupler section 36 may be used to connect the endoscope 14 to the imaging and control system 12. The coupler section 36 may be used to communicate various functions between the endoscope 14 and the imaging and control system 12. In examples, the coupler section 36 may transmit communication signals, electronic signals, electrical signals, power signals, fluids including water and air, and light waves, etc. The coupler section 36 may comprise a portion of the endoscope 14 and may be configured for a specific configuration of the imaging and control system 12. For example, the coupler section 36 may be configured to transmit light generated by the light source unit 22 to the endoscope 14 using a photoconductor 39, as discussed with reference to FIG. 3. With the present disclosure, a light processing adapter may be connected to the imaging and control system 12 for coupling to an endoscope incorporating or equipped with a light-generating device. Such a light processing adapter may convert light generated by the light source unit 22 into electronic instructions for operating an equipped light-generating device to replicate the light generated by the light source unit 22, as discussed with reference to FIG. 4.

[0027] 3 is a block diagram illustrating a light guide connector 100 coupling an imaging and control system 102 to an endoscope 104. The imaging and control system 102 may comprise an example of the imaging and control system 12 of FIGS. 1 and 2. The imaging and control system 102 may comprise a controller 105, a video processor 106, a memory 108, a light source 110, and a filter 112. In an example, the controller 105 may comprise an example of the control unit 16 of FIG. 2, the light source 110 may comprise an example of the light source unit 22 of FIG. 2, and the video processor 106 may comprise an example of the image processing unit 42 of FIG. 2. The endoscope 104 may comprise a scope cable 114, a scope handle 116, a scope working shaft 118, an imaging device 120, a lens 122, and a light guide 124. In an example, scope cable 114 can comprise an example of cable section 34 of Figure 2, scope handle 116 can comprise an example of handle section 32 of Figure 2, and scope working shaft 118 can comprise an example of insertion section 28 of Figure 2. In an example, light guide connector 100 can include an example of socket 37 of Figure 1, whereby scope cable 114 can comprise a coupler similar to coupler section 36 of Figure 1.

[0028] The light guide connector 100 can be used to communicate electronic signals and light waves between the imaging and control system 102 and the endoscope 104. In FIG. 3 , light waves can be indicated by dashed lines and wired signals can be indicated by solid lines. The light guide connector 100 can transmit electronic signals generated by the imaging device 120 to the imaging and control system 102 and control signals from the controller 105 to the endoscope 104. For example, control signals for various operating features of the endoscope 104, such as ablation, suturing, RF signal generation, and cryogenic features, can be communicated from the controller 105 to the endoscope 104. Additionally, light waves from the light source 110 can be communicated to the endoscope 104 through the light guide connector 100.

[0029] The light guide connector 100 may include a photoconductor 126 and electrical wiring 128. The endoscope 104 may include a photoconductor 130 and electrical wiring 132. The imaging and control system 102 may include a photoconductor 134 and control wiring 136. The light guide connector 100's photoconductor 126 may connect the endoscope 104's photoconductor 130 to the light source 110 via the photoconductor 134, and the light guide connector 100's electrical wiring 128 may connect the endoscope 104's electrical wiring 132 to the controller 105 via the control wiring 136.

[0030] The endoscope 104 can control the transmission of electronic imaging signals from the imaging device 120 to the imaging and control system 102. For example, light can enter the lens 122 in the endoscope 104. The light can be received by the imaging device 120. In examples, the imaging device 120 can comprise a solid-state device such as a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS). The imaging device 120 can convert light waves received from the lens 122 into electronic signals. The electronic signals can pass through appropriate conductors in the electrical wiring 132 through the scope working shaft 118, the scope handle 116, and the scope cable 114 to the electrical wiring 128 of the light guide connector 100. The electrical wiring 128 of the light guide connector 100 can comprise appropriate couplers for transmitting the electronic signals from the imaging device 120 through the control wiring 136 to the imaging and control system 102. Video processing unit 106 may thereby receive electronic signals from imaging device 120 for display on a video monitor, such as output unit 18 of Figure 1, after appropriate processing, etc. Memory 108 may include various red, green, and blue image memories for processing signals generated by imaging device 120.

[0031] In addition to optical and imaging signals, light guide connector 100 can relay other types of data, such as control signals for various functions of endoscope 104. Specifically, control wiring 136, electrical wiring 128, and electrical wiring 132 can additionally be used to carry control signals for diagnostic and treatment functions of endoscope 104. For example, a user can input settings for the functionality of endoscope 104 in controller 105, such as using input unit 20 (FIG. 2). Controller 105 can then generate appropriate control signals for transmission to light guide connector 100. Electrical wiring 128 can be configured to carry control signals over additional conductors or the same conductors that carry imaging signals, such as using lead 49 (FIG. 2).

[0032] Additionally, although not shown in FIG. 3, the light guide connector 100 may include appropriate tubing or piping for carrying fluids, such as saline, irrigation fluid, air, insufflation gases, and other gases, to and from the endoscope 104.

[0033] The light source 110 can control the intensity and type of light generated by the imaging and control system 102. For example, the light source 110, or features of the imaging and control system 102, such as the input unit 20 (FIG. 1), can include control features, such as buttons or knobs, to start and stop the generation of light waves, control the intensity of the light waves, and so on. The imaging and control system 102 includes control features for activating or deactivating different types of filters 112, such as color filters. Thus, a user of the imaging and control system 102 can initiate settings in the imaging and control system 102 for light to be transmitted to the light guide 124 of the endoscope 104. Typical user settings include 1) on / off, 2) light intensity, and 3) light color. In examples, 1) the on / off setting can be a function of intensity (e.g., zero intensity is equal to off), 2) light intensity can be a function of the current or electrical signal provided to the light source 110, and 3) the color setting can be a function of the filter 112 applied to the output of the light source 110. Each of 1), 2), and 3) can be set by a user in control device 105 and can be designated as a characteristic of the light waves emitted from light source 110. Photoconductor 126 of light guide connector 100 may comprise an appropriate coupler, conductor, or pipe for transmitting light waves from photoconductor 134 of light source 110 to light guide 124. Light waves from light source 110 can thereby travel through filter 112, photoconductor 134 of imaging and control system 102, photoconductor 126 of light guide connector 100, photoconductor 130 of endoscope 104 (including photoconductor 39 of FIG. 2), and light guide 124, thereby allowing the light waves to exit endoscope 104 for illuminating an anatomy into which endoscope 104 is inserted.

[0034] Configured in this manner, the light guide connector 100 can be configured to relay signals and light waves between the imaging and control system 102 and the endoscope 104 without modification. In an example, the endoscope 104 can be specifically configured for operation 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 obstruction or without introducing distortions such as discoloration or intensity changes. Additionally, the light guide connector 100 can provide electronic communication paths between the imaging device 120 and the video processing unit 106, and between the control unit 105 and the endoscope 104 functions. Thereby, the light guide connector 100 does not include the ability to interpret, analyze, or modify the optical, imaging, and control signals. Furthermore, the light guide connector 100 can be mechanically configured to couple to certain types of endoscope plugs, such as the coupler section 36 of FIG. 1 . Therefore, other types of endoscopes that are not configured to accept the output of imaging and control system 12 or that are not mechanically configured to mate with socket 37 will not be interoperable or compatible with imaging and control system 12.

[0035] 4 is a block diagram illustrating an adapter 150 of the present disclosure that couples the imaging and control system 102 of FIGS. 1 and 2 to an endoscope 152. The adapter 150 may include a conversion adapter of the present disclosure that allows a standardized connector of the endoscope 152 to interface with a non-standardized connector of the imaging and control system 102.

[0036] 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 configured similarly to that disclosed with reference to FIG. 3 to provide a light output at a photoconductor 134 and to send and receive communication signals via control wiring 136.

[0037] Endoscope 152 may include a scope cable 154, a scope handle 156, a scope working shaft 158, an imaging device 160, a lens 162, a light guide 164, and a light generator 166. Endoscope 152 may be configured similarly to endoscope 104 of FIG. 3, except that endoscope 152 may include light generator 166 rather than having light conductor 130 extending therethrough as in endoscope 104. In an example, scope cable 154 may be configured similarly to cable section 34 of FIG. 2, scope handle 156 may be configured similarly to handle section 32 of FIG. 2, and scope working shaft 158 ​​may be configured similarly to insertion section 28 of FIG. 2 with imaging device 160 in place of its proximal light conductor. In an example, light guide connector 100 may include an example of socket 37 of FIG. 1.

[0038] The adapter 150 can be used to convey information from the light guide connector 100 to the endoscope 152. The adapter 150 can be configured for insertion into the socket 37 (FIG. 1) to receive light from the light source unit 22 and control signals from the control unit 16, as well as various air sources. The light guide connector 100 can be used to convey electronic signals and light waves between the imaging and control system 102 and the adapter 150. In FIG. 4, light waves can be indicated by dashed lines and wired signals can be indicated by solid lines. The adapter 150 can transmit electronic signals generated by the imaging device 120 to the light guide connector 100 for transmission to the imaging and control system 102. The adapter 150 additionally transmits electronic signals from the controller 105 and the light guide connector 100 to the endoscope 152. The adapter 150 can receive light waves from the light guide connector 100 generated by the light source 110 and convert such light waves into combined signal wiring 170 for transmission to the light-generating device 166. The light-generating device 166 may comprise a light source configured to output light waves. In an example, the light-generating device 166 may comprise a light-emitting diode (LED). In an additional example, the light-generating device 166 may be configured to generate light of different colors.

[0039] The adapter 150 may include a combination signal wiring 170 that may extend through the endoscope 152. The combination signal wiring 170 may be bifurcated into an optical signal wiring 170A for communication with the light-generating device 166 and an imaging signal wiring 170B for communication with the imaging device 160. The imaging and control system 102 may include a photoconductor 134 and control wiring 136. The photoconductor 126 and electrical wiring 128 of the light guide connector 100 may be connected to the adapter 150, which may transmit the combination signal wiring 170 to the light-generating device 166 and the imaging device 160. In an example, the combination signal wiring 170 may include a universal cord that includes one or more of an air passage, a water passage, a biopsy passage, and a photoconductor.

[0040] The endoscope 152 can control the transmission of electronic imaging signals from the imaging device 120 to the imaging and control system 102. For example, light can enter the lens 162 in the endoscope 152. The light can be received by the imaging device 160. In examples, the imaging device 160 can comprise a solid-state device such as a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS). The imaging device 160 can convert light waves received from the lens 162 into electronic signals. The electronic signals can pass through appropriate conductors in the combined signal wiring 170 through the scope working shaft 158, the scope handle 156, and the scope cable 154 to the electrical wiring 128 of the light guide connector 100. The electrical wiring 128 of the light guide connector 100 can comprise appropriate couplers for transmitting the electronic signals from the adapter 150 through the control wiring 136 to the imaging and control system 102. Video processing unit 106 may thereby receive, after appropriate filtering, etc., electronic signals from imaging device 160 for display on a video monitor, such as output unit 18 of FIG.

[0041] The light source 110 can control the intensity and type of light generated by the imaging and control system 102, as previously described. For example, the light source 110, or a feature of the imaging and control system 102, such as the input unit 20 (FIG. 1), can include control features, such as a button or knob, to control 1) the light source 110 on / off, 2) the intensity of the light from the light source 110, and 3) the color of the light as determined by the filter 112, such as starting and stopping the generation of light waves and controlling the intensity of the light waves. The photoconductor 126 of the light guide connector 100 can include an appropriate coupler, conductor, or pipe for transmitting the light waves from the photoconductor 134 of the light source 110 to the adapter 150. The adapter 150 can receive the light waves from the photoconductor 134 and convert sensed characteristics of the light waves, such as on / off, intensity, and color, into electronic control signals for the light-generating device 166. The adapter 150 may include appropriate sensors and circuitry for converting light waves into electronic control signals, as discussed with reference to Figures 5-15. Light waves from the light source 110 may thereby travel through the filter 112, the photoconductor 126 of the light guide connector 100, and to the adapter 150, which then transmits the light-generating signal along combined signal wiring 170 to the light-generating device 166, which may then output the light into the light guide 164, thereby allowing the light waves to exit the endoscope 152 for illuminating the anatomy into which the endoscope 152 is inserted. Thus, when an operator of the imaging and control system 102 requests light, such as by commanding the light source 110 to be turned on, the light-generating device 166 may be commanded to generate light waves equivalent in intensity and color to the light waves exiting the light source 110.

[0042] So configured, the adapter 150 can be configured to relay, with conversion, modification, or interpolation, signals between the imaging and control system 102 and the endoscope 152. The endoscope 152 need not be specifically designed to operate with the imaging and control system 102, but can include any type of light-generating device 166 and coupling section. In an example, the endoscope 152 can be adapted for operation with the imaging and control system 102 with the use of the adapter 150. The adapter 150 can provide an appropriate mechanical interface between the endoscope 152 and the imaging and control system 102, as well as appropriate conversion of the control inputs for 1), 2), and 3) input to the light-generating device 166 at the controller 105. In addition to optical signals, such as light waves, and imaging signals, such as electronic communication signals, the adapter 150 can relay various fluids, such as water and air, as well as other types of data, such as control signals, between the light guide connector 100 and the endoscope 152. Adapter 150 may include reusable parts that are easily cleaned and sterilized, while endoscope 152 may be configured as a disposable scope that does not need to be cleaned and sterilized. Single-use endoscopes can be destroyed, such as by being broken into smaller, unusable pieces, so that they cannot be reused.

[0043] Figure 5 is a rear perspective view of the adapter 200 of the present disclosure, showing the main housing 202 and plug component 204. Figure 6 is a front perspective view of the adapter 200 of Figure 5, showing the socket component 206 for receiving an endoscope plug. The adapter 200 may comprise an example of the adapter 150 of Figure 4, or may comprise a conversion adapter described herein. Figures 5 and 6 are considered together.

[0044] The plug component 204 may include an air coupler 208, a photoconductor assembly 210, and an electrical lead 212. The air coupler 208 and the photoconductor 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 coupler 208 and the photoconductor assembly 210 may be coupled to the light guide connector 100 ( FIG. 3 ) or may be directly coupled to the light source unit 22 ( FIG. 1 ) or other components of the imaging and control system 12. The plug component 204 may be inserted into a receptacle 216 of the main housing 202. The main housing 202 may include protrusions 218A and 218B that may be coupled to a receptacle, such as the socket 37 ( FIG. 1 ) in the light guide connector 100 or the light source unit 22, via a twist-lock or push-pull action. Main housing 202 may include other features, such as pads 220A and 220B, to provide ergonomic engagement with a user's fingers. In an example, plug component 204 may include a non-standardized connector for use with cables commonly used in the endoscopy industry.

[0045] Adapter 200 may be configured to receive light waves at photoconductor assembly 210, air at air coupler 208, and control signals at electrical lead 212. In an example, plug component 204 may be configured similar to plug portion 48 of coupler section 36 (FIG. 2), and electrical lead 212 may operate similar to lead 49. Thus, control signals generated by imaging and control system 12 (FIGS. 1 and 2) may be transmitted to adapter 200. Photoconductor assembly 210 may be configured similar to photoconductor 39 (FIG. 2). Thus, light output by light source unit 22 may be transmitted to adapter 200.

[0046] Socket component 206 may include an opening 222 for receiving an endoscope plug, such as a plug that connects to combined signal wiring 170 (FIG. 4). Opening 222 may include an air coupler 230 (FIG. 8) and an electrical coupler 232 (FIG. 8) for communication with endoscope 152 (FIG. 4). In an example, electrical coupler 232 may include a standardized connector for use with computer peripheral systems and components. As discussed with reference to FIGS. 7 and 8, adapter 200 allows air and control signals to pass through main housing 202 and plug component 204 via fluid coupler 230 and electrical coupler 232.

[0047] Figure 7 is a rear end view of adapter 200 of Figures 5 and 6, showing photoconductor assembly 210 and air coupler 208. Figure 8 is a front end view of adapter 200 of Figures 5 and 6, showing air coupler 230, electrical coupler 232, and alignment posts 234A and 234B. Figures 7 and 8 are considered simultaneously.

[0048] The plug component 204 may be inserted into the socket 37 (FIG. 1) of the light source unit 22. When inserted, the electrical leads 212 may connect to electrical contacts in the socket 37 to allow transmission of electrical signals from the imaging and control system 12, such as from the control unit 16 and the light source unit 22. The plug component 204 may comprise a plug for use with a universal cable socket that allows features of the endoscope to communicate with the imaging and control system.

[0049] A plug for endoscope 152 ( FIG. 4 ) may be inserted into opening 222. Opening 222 may have an irregular shape, such as a roughly square with one rounded side, to facilitate assembly with the endoscope plug in a single orientation. Alignment posts 234A and 234B may be positioned in opening 222 to facilitate coupling with the endoscope plug. For example, alignment posts 234A and 234B may comprise cylindrical posts that a cylindrical socket in the endoscope plug can slide over to facilitate alignment. Alignment posts 234A and 234B may also relieve stress on fluid coupler 230 and electrical coupler 232. In an additional example, alignment posts 234A and 234B may be spring-loaded to facilitate extraction of adapter 200. For example, alignment posts 234A and 234B may be biased to an extended position so that they can be compressed when adapter 200 is connected to the control unit. The compressed spring force can thereby facilitate removal of adapter 200 when pulled by an operator or user. An electrical coupler 232 can be positioned within opening 222. Electrical coupler 232 can comprise a standardized computer peripheral connector, such as a USB socket.

[0050] Air tubing may be connected to air coupler 208 and air coupler 230. Air tubing 242 ( FIGS. 10 and 11 ) may extend between air coupler 208 and air coupler 230 to allow air to pass through adapter 200. For example, air coupler 208 and air coupler 230 may be connected to air, carbon dioxide, saline, water, and other fluids to perform various functions, including insufflation. In examples, air coupler 208 and air coupler 230 may comprise hose couplers or hose fittings, with or without valves. In examples, adapter 200 may be configured to simply allow air to pass through main housing 202 and plug component 204 without interference, regulation, or control. However, in some examples, adapter 200 may be configured to actively control air flow through main housing 202 and plug component 204 based on electronic signals received from control unit 16 ( FIG. 1 ) or another source, such as by including an electronically controlled valve.

[0051] The photoconductor assembly 210 may be configured to receive light waves from a light source. Specifically, an end of the photoconductor assembly 210 may face the output of a bulb or LED in the light source unit 22. The photoconductor assembly 210 may extend to the plug component 204 and emit light waves to the sensor package 245 ( FIG. 9 ). As discussed in more detail below, electronics connected to the sensor package 245 may convert the light waves into instructions for the light-generating device 166 ( FIG. 4 ), which may be transmitted through the electrical coupler 232. In an example, the photoconductor assembly 210 may include a photoconductor 240 disposed in the sheath 241. In an example, the photoconductor 240 may include a light pipe or a bundle of optical fibers. The photoconductor 240 may include an optical receiver. For example, the photoconductor 39 ( FIG. 2 ) of the endoscope 14 may include the proximal end of a bundle of optical fibers extending through the cable section 34 and the insertion section 28, and thus may include a bundle of optical fibers. Therefore, to facilitate flexibility, it is desirable to fabricate the photoconductor 39 from multiple optical fibers. However, the photoconductor 240 may comprise a light pipe, which may comprise a single piece of light conductor having a much larger diameter than an individual optical fiber. This allows the photoconductor 240 to be more robust, such as being stiffer and more resistant to heat. A further description of the photoconductor assembly 210 is provided with reference to FIG. 13.

[0052] Figure 9 is a front perspective view of the adapter 200 of Figures 5 and 6 with the main housing 202 removed to show the support bracket 203 connected to the plug component 204 and the socket component 206. Figure 9 additionally shows the sensor package 245. Figure 10 is a front perspective view of the adapter 200 of Figure 9 with the support bracket 203 and the socket component 206 removed to show the air coupler 230, the electrical coupler 232, the photoconductor 240, and the air tubing 242. Figures 9 and 10 are considered together.

[0053] The photoconductor 240 may be connected to the photoconductor assembly 210 extending from the plug component 204. The photoconductor may direct light to the sensor package 245. An air line 242 may be connected to the air coupler 230 and the air coupler 208 (FIGS. 5 and 7). An optical board 244 may be connected to the control board 246 of the plug component 204 via fasteners 248 and posts 250. The control board 246 may be connected to the prongs 254 of the electrical leads 212. The control board 246 may be connected to the communication board 252 via a connector 253, which may be mounted on board 255. The connector 253 may be connected to the communication board 252 via wiring 256 (FIG. 11). The optical board 244 may be connected to the communication board 252 via wiring 258 (FIG. 11). The communication board 252 may be connected to the electrical coupler 232 for transmitting control signals and light-generating signals to the endoscope 152 (FIG. 4). Thereby, when plug component 204 is inserted into socket 37 (FIG. 1), electrical leads 212 can be placed in communication with endoscope 152 through prongs 254, communication board 252, and electrical coupler 232. Plug component 204 can be shaped to be received within a universal cord socket of an endoscope system, and electrical leads 212 can be distributed around plug component 204 for engaging with mating leads in the universal cord socket. Similarly, when plug component 204 is inserted into socket 37, air line 242 can be placed in communication with endoscope 152 through air line 242, air coupler 208, and air coupler 230. Additionally, photoconductor assembly 210 can be placed in alignment with sensor package 245.

[0054] FIG. 11 is a cross-sectional view through the adapter 200 of FIG. 10 showing the air tubing 242 passing through the adapter 200 and the sensor package 245 positioned proximate to the photoconductor 240.

[0055] Air tubing 242 may comprise a conduit connected to air coupler 208 and air coupler 230. In an example, air tubing 242 may comprise rubber or plastic pipe or tubing. Air tubing 242 may be connected to appropriate fittings at air coupler 208 and air coupler 230 to provide a leak-proof passageway through adapter 200. For example, air coupler 208 and air coupler 230 may comprise barb fittings over which air tubing 242 fits. Air coupler 208 may comprise a male protrusion that can mate with a mating female receptacle on socket 37 ( FIG. 1 ). Air coupler 230 may comprise a female receptacle that can receive a mating male protrusion on a connector of scope cable 154 ( FIG. 4 ). Air coupler 208 may be securely supported by end face 214 of plug component 204, and air coupler 230 may be securely supported by socket component 206. Air tubing 242 may run unsupported through adapter 200 between air coupler 208 and air coupler 230. In doing so, support bracket 203 and control board 246 may include suitable openings to allow air tubing 242 to run therethrough.

[0056] Figure 12 is a cross-sectional view through the adapter 200 of Figure 10 showing the photoconductor 240 facing the sensor package 245 mounted on an optical substrate 244 that is connected to the electrical coupler 232. Figure 12 is considered with additional reference to Figure 11.

[0057] The photoconductor assembly 210 can be attached to the socket component 206. Specifically, the sheath 241 can be inserted into a receptacle 259 at the end face 214 of the socket component 206. The distal end of the photoconductor 240 can protrude through the optical board 244 and the support bracket 203 so as to be positioned within the main housing 202 proximate the sensor package 245. The optical board 244 can be mounted to the support bracket 203 via fasteners 248. The optical board 244 can be placed in communication with the communication board 252 via an appropriate connection. In an example, wiring 258 can connect the optical board 244 and the communication board 252. In another example, the optical board 244 can be connected to the control board 246. In an 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. As discussed with reference to FIG. 14 , the sensor package 245 may include one or more light sensors for interpreting various characteristics of the light waves emanating from the photoconductor 240. The sensor package 245 or other suitable electronics can convert the output of the light sensors into instructions for operating the light-generating device 166 ( FIG. 4 ). The instructions for operating the light-generating device 166, along with other control signals from the electrical leads 212, can be communicated to the electrical coupler 232. In an example, the electrical coupler 232 can include an input / output device configured to send and receive not only electronic communication signals but also power, such as electrical current. In an example, the electrical coupler 232 can include a Universal Serial Bus (USB) port, specifically a USB-C port. Thus, outputs from the sensor package 245 and the various prongs 254 from the control unit 16 can be communicated to various components of the endoscope 152 ( FIG. 4 ). Various pins in the electrical coupler 232 can mate with one or more of the electrical leads 212 in the plug component 204.

[0058] The adapter 200 of the present application may comprise a conversion adapter configured to allow hardware typically used with an endoscope system to be attached to hardware more specific to a computer system. Thus, a first end of the adapter may comprise a first connector configured to interface with a mating connector of an endoscope system, while a second end of the adapter may comprise a second connector configured to interface with a mating connector of a computing system. In an example, the first connector may be configured to connect to a non-standardized computer peripheral connector, and the second connector may be configured to connect to a standardized computer peripheral connector. In an example, the adapter 200 and the conversion adapters described herein may be configured to convert a manufacturer-specific endoscope interface to a computer interface common in the industry.

[0059] In an example, the first connector can be configured to connect to a receptacle of a light-generating device of an endoscopic system, and the second connector can be configured to connect to a USB plug of the single-use endoscope. Specifically, the plug component 204 can comprise a plug configured for insertion into a universal cord socket of an endoscopic system, as discussed herein, and the electrical coupler 232 can comprise a socket configured to receive the USB plug of the single-use endoscope. At least one of the electrical leads of the electrical coupler 232 can carry a light intensity signal from the adapter 200 to the endoscope. The plug component 204 can additionally comprise an optical receiver, such as a photoconductor or light pipe, that can receive light from a video processing unit or a light-generating device.

[0060] In an example, the plug component 204 and the universal cord connector can be configured to communicate signals from the universal cord. In an example, the universal cord can include one or more of an air passageway, a suction passageway, a fluid passageway, a photoconductor, and one or more conductors for transmitting electrical signals such as video signals, power for a light or illumination unit, and other components. In an example, the plug component 204 can include an optical plug configured for use with a light-generating device. The plug component 204 can include a cylindrical body having a circular outer periphery. In an example, the cylindrical body can include a stepped cylindrical body having multiple outer circular peripheries. Electrodes 212 can be positioned on the circular outer periphery to exchange electrical signals, such as transmitting and receiving electronic signals. Accordingly, the form factor of the plug component 204 can be configured to mate with a universal cord socket. The present disclosure discloses specific form factors for connecting the various passageways, photoconductors, and electrical wiring in the universal cord to an endoscopic system, such as an imaging system or a light-generating device. However, various endoscope manufacturers may utilize different form factors for the plug attached to the universal cord to connect with the socket of their specific endoscope system. Therefore, these form factors may not be standardized because they are typically not intended to function with endoscopes from different manufacturers. Therefore, in other examples, the plug component 204 may have other form factors, such as a linear cross-sectional shape, and electrodes positioned in patterns or arrangements other than those shown. In examples, the plug component 204 may comprise an endoscope connector as described in U.S. Patent No. 5,999,249 to Saiga entitled "Endoscope Connector," U.S. Patent No. 5,999,249 to Suzuki entitled "Endoscope connector and Endoscope," and U.S. Patent No. 5,999,249 to Watanabe et al. entitled "Connector System," the contents of each of which are hereby incorporated by reference.

[0061] In an example, electrical coupler 232 may comprise a socket configured to accept a plug of a standardized computer peripheral component. As discussed herein, an endoscope, such as endoscope 152 of FIG. 4, may comprise a standardized computer peripheral plug compatible with electrical coupler 232. Examples of standardized connectors may include Universal Serial Bus (USB) ports and plugs, including USB-A, USB-B, USB-C, mini-USB, and micro-USB varieties, serial ports and plugs, parallel ports and plugs, gaming ports and plugs, various RJ connectors that may be used for telephone systems, RJ45 connectors used for Ethernet systems, and others. In an example, electrical coupler 232 may comprise a USB-C plug constructed in accordance with Non-Patent Document 1 entitled "Universal serial bus interfaces for data and power - Part 1-3: Common components - USB Type-C® cable and connector specification" and "Universal Serial Bus Type-C Cable and Connector Specification," available from the USB 3.0 Promoter Group, the contents of each of which are hereby incorporated by reference.

[0062] The electrical coupler 232 can be positioned within the opening 222. The opening 222 can include a receptacle having an outer cross-sectional shape configured to mate with a plug of the endoscope 152. In the illustrated example, the opening 222 can have a flat bottom surface, two parallel side walls extending from the flat bottom surface, and a curved top surface connecting the two parallel side walls. Filleted or chamfered surfaces can connect the top and bottom surfaces with the side walls. A USB-C style plug or other standardized plug can be positioned to extend from a plug shaped to mate with the opening 222, such that upon insertion of the plug into the opening 222, the standardized connector can mate with the electrical coupler 232.

[0063] Figure 13 is a cross-sectional view through the adapter 200 of Figure 10 showing the photoconductor assembly 210. The photoconductor assembly 210 may include a photoconductor 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.

[0064] The proximal end of the photoconductor 240 may include a surface 268. The surface 268 may be positioned to receive light waves produced by the light source unit 22 exiting the socket 37 ( FIG. 1 ). The photoconductor 240 may extend distally toward the sensor package 245. A sheath 241 may surround the proximal portion to facilitate assembly with the plug component 204. Filters 264A and 264B may be positioned proximate the surface 268 to receive light entering the photoconductor 240. The filters 264A and 264B may include polarizing films angled relative to each other to reduce the intensity of light transmitted to the photoconductor 240. In an example, the intensity of light entering the photoconductor 240 may be reduced as a safety feature to limit the temperature of the light reaching the sensor package 245. Furthermore, very high light intensities could potentially electronically overwhelm the sensors within the sensor package 245. Sensor package 245 may be configured to have a memory in which information about the magnitude of the intensity reduction provided by filters 264A and 264B is stored so that instructions for operating light-generating device 166 (FIG. 4) may be adjusted accordingly. Further discussion of the operation of sensor package 245 is provided with reference to FIGS. 14 and 15.

[0065] An end cap 260 may be placed around filters 264A and 264B to secure them to surface 268 of photoconductor 240. End cap 260 may include a lens 262 and a fitting 270. Fitting 270 may include a retention device for holding filters 264A and 264B against photoconductor 240. End cap 260 may then be positioned over fitting 270 to hold filters 264A and 264B in place. Lens 262 may include a piece of glass or quartz to allow light waves to pass through without alteration. Lens 262 may protect filters 264A and 264B.

[0066] 14 is a block diagram illustrating a light processing adapter 300 of the present disclosure. The light processing adapter 300 may include a housing 302, a light pipe assembly 304, a first input / output (I / O) device 306, a second input / output (I / O) device 308, an air passage 310, and a controller 312. The controller 312 may include a circuit board 314, a processing unit 316, and a memory 318. The light pipe assembly 304 may include a filter 320, a light pipe 322, a first sensor 324A, and a second sensor 324B.

[0067] Air passageway 310 may be configured similarly to air coupler 208, air tubing 242, and air coupler 230. Air passageway 310 may be configured as a pipe or tube to allow fluids such as air, gas, and water to pass through adapter 300.

I / O device 308 may be configured as electrical coupler 232. I / O device 306 may be configured to relay electronic communication signals to and from adapter 300 for communication with a light-generating endoscope.

[0069] In an example, I / O device 306 and I / O device 308 may communicate using wireless communication signals, such as Bluetooth®, WiFi®, Zigbee®, infrared (IR), near field communication (NFC), 3GPP®, or other technologies. In an example, I / O device 306 and I / O device 308 may have a wired connection or may have a port for accepting a wire for a wired connection. In an example, I / O device 306 and I / O device 308 may communicate using one or more of the IEEE 802.15.6-2012 protocol, the MICS protocol, and the MBAN protocol.

[0070] Filter 320 may be configured as filters 264A and 264B. In an example, filter 320 may comprise an absorptive filter that can absorb wavelengths of certain colors and pass wavelengths of other colors. In an example, filter 320 may comprise an interference filter that reflects wavelengths in certain spectral bands and transmits wavelengths in other spectral bands. In an example, filter 320 may comprise a pair of polarizing filters that are offset in rotation to pass light waves of certain polarizations while blocking light waves of other polarizations.

[0071] Light pipe 322 can be configured as photoconductor 240. Light pipe 322 can comprise a single or monolithic component fabricated from optical acrylic, polycarbonate, or other material. In an alternative example, light pipe 322 can be replaced by a bundle of optical fibers made from silica, plastic, or other material. Light pipe 322 can extend between filter 320 and sensors 324A and 324B, such that light exiting filter 320 can enter one end face of light pipe 322 and light exiting the opposite face of light pipe 322 can direct light waves toward sensors 324A and 324B.

[0072] The first sensor 324A and the second sensor 324B can be configured as part of the sensor package 245 (FIGS. 11 and 12). In an example, the first sensor 324A can include a light intensity sensor. In an example, the first sensor 324A can include a photodiode, a photoresistor, a phototransistor, and a photovoltaic light sensor. In an example, the second sensor 324B can include a color sensor. In an example, the second sensor 324B can include a light-to-photocurrent sensor, a light-to-analog voltage sensor, and a light-to-digital sensor.

[0073] Circuit board 314 can comprise structural components for electrically and structurally coupling electrical components of adapter 300. For example, circuit board 314 can comprise a silicon wafer or chip to which electrical connections are attached for electronic coupling of processing unit 316, memory 318, sensors 324A, and 324B, etc. Circuit board 314, as connected to processing unit 316, memory 318, and sensors 324A and 324B, can operate as a transducer for converting light waves into electronic signals, as described herein.

[0074] Processing unit 316 may comprise 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. Processing unit 316 can execute instructions stored in memory 318 to operate components of adapter 300, such as sensors 324A and 324B. In an example, the processing unit and memory are not required and adapter 300 can operate as a single integrated circuit, whereby the outputs of sensors 324A and 324B can be transmitted directly by I / O devices 306 and 308.

[0075] Memory 318 may comprise any suitable storage device, such as non-volatile computer-readable memory, magnetic memory, flash memory, volatile memory, and programmable read-only memory. Memory 318 may contain stored instructions for processing unit 316 to control the operation of adapter 300. For example, memory 318 may contain instructions for operating I / O devices 306 and 308 and sensors 324A and 324B. Memory 318 may additionally contain reference data for comparing data from sensors 324A and 324B, such as a look-up table for correlating sensed light intensity to power input to light-generating unit 166 ( FIG. 4 ) and other information, which can be used to convert light waves of a particular intensity and color into one or more electronic signals for generating light of the same or approximately the same intensity and color. In an example, the memory 318 may include a look-up table having light intensities from zero output to maximum output of the light source 110 (FIG. 4) correlated to current input to the light-generating device 166 (FIG. 4), from zero input to maximum input to the light-generating device 166.

[0076] In an example, memory 318 may include instructions for increasing or decreasing the light signal generated by light-generating device 166 based on the effect of filter 320. For example, memory 318 may include appropriate increase or decrease factors to apply to the lookup table discussed above. For example, the processing unit may determine that filter 320 reduces the output of light source 110 by 50 percent so that the output of sensors 324A and 324B may be increased by 50 percent before looking up the appropriate current to generate to operate light-generating device 166.

[0077] In a further example, the memory 318 may include instructions for causing the processing unit 316 to perform compensation for the light source 110. For example, various light sources, such as xenon bulbs, are known to dim over time, emitting less light than desired. Thus, an imaging and control system that requests a specific light intensity output may result in the light source outputting light having, for example, 95 percent of the requested intensity. The light processing adapter of the present disclosure may be configured to compensate for such dimming. In an example, the imaging and control system 102 may be configured to provide 0% and 100% light intensity for the light source 110 upon startup. The light processing adapter 300 may store in the memory 318 appropriate 0% and 100% intensity outputs, such as the intended undim output, for a particular model of the imaging and control system 102. Thus, the processing unit 316 can determine that the light source 110 is only outputting 95% of the output required by the imaging and control system 102 and can appropriately increase the output of the light generating unit 166 so that the output of the light generating unit 166 matches the light intensity required by the imaging and control system 102, even though the light source 110 is not providing the required light intensity.

[0078] FIG. 15 is a block diagram illustrating the operation of a method 400 for converting light generated by the imaging and control system 12 into light control signals for the light-generating device 166 of the endoscope 152.

[0079] In operation 402, light may be generated by a first light-generating device of the imaging and control system. For example, the light may be generated by light source 110 of imaging and control system 102 (FIG. 4). A user may input on / off, intensity, and color settings in a user interface. For example, a user may utilize output unit 18 and input unit 20 (FIG. 1) to input on / off, intensity, and color settings for light source 110.

[0080] In operation 404, light from a first light-generating device, such as light source 110, may be received at adapter 300, which is connected to imaging and control system 102 (FIG. 4). Light waves from light source 110 may enter photoconductor assembly 210 of adapter 300. Photoconductor assembly 210 may be positioned opposite a light bulb or light-emitting diode in light source 110 when adapter 300 is inserted into socket 37 (FIG. 1).

[0081] In operation 406, a characteristic of the light may be sensed with a sensor in the adapter. For example, a first sensor 324A (FIG. 14) may be used to sense the intensity of the light from the light source 110. Also, in the example, a second sensor 324B (FIG. 14) may be used to sense the color of the light from the light source 110. Light waves may 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 waves may activate appropriate elements in the first sensor 324A and the second sensor 324B to cause the generation of an electrical signal.

[0082] In operation 408, the characteristics of the light sensed by the sensor may be converted into a control signal for generating light at a second light-generating device of the endoscope. For example, the light intensity sensed by the first sensor 324A may be converted into a command for the light-generating device 166 (FIG. 4) of the endoscope 152 (FIG. 4) to generate light at the same intensity. Also, in an example, the light color sensed by the second sensor 324B may be converted into a command for the light-generating device 166 to generate light of the same color.

[0083] In an example, the processing unit 316 may receive a signal from the first sensor 324A related to the intensity of light from the light source 110. The light intensity from the light source 110 may have a linear relationship with the current input to the light source 110. The current output from the first sensor 324A may thereby be increased or decreased by the processing unit 316 as a control signal for the light-generating unit 166. The processing unit 316 may consult a lookup table stored in the memory 318 that has values ​​of the output of the first sensor 324A associated with values ​​of the current provided to the light-generating unit 166 to produce an equivalent intensity of light output by the light source 110. The memory 318 may be provided with lookup tables for different combinations of light source 110 and light-generating unit 166. In an example, the processing unit 316 can receive signals from the imaging and control system 12 providing an identification of the light source 110, e.g., manufacturer, type of light, type of bulb, type of color, type of LED, etc., as well as receive identification signals from the endoscope 152 (FIG. 4) providing an identification of the light-generating device 166, e.g., manufacturer, type of light, type of bulb, type of color, type of LED, etc. The processing unit 316 can thereby consult a lookup table having appropriate information for converting the determined light output of the imaging and control system into a determined control input to the light-generating device 166. Additionally, as discussed herein, the processing unit 316 can condition the outputs of the sensors 324A and 324B not only to adjust the light intensity filter implemented in the adapter 300 using the filter 320, but also to provide light intensity compensation for dimming of the output of the light source 110 that occurs over time.

[0084] In operation 410, the light control signal can be transmitted through the adapter to a second light-generating device of the endoscope. For example, the light control signal generated by the processing unit 316 can be transmitted via the combined signal line 170 and the light signal line 170A to the light-generating device 166 of the endoscope 152. The light-generating device 166 can generate light waves having an intensity based on the received output of the adapter 300. Furthermore, the light-generating device 166 can produce light waves of a color determined by the adapter 300. Thus, the light output of the light-generating device 166 can match the output of the light source 110 in intensity and color. As such, the light-generating device 166 can emit light waves that can be illuminated at tissue, such as with the use of the light guide 164 (FIG. 4).
