[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS 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 in their entireties.

[0002] FIELD OF THE DISCLOSURE 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 therapeutic procedure.

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

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

[0005] Conventional endoscopes can 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 fluid channels) to an anatomical region, providing passage for one or more therapeutic devices for sampling or treating an anatomical region (e.g., via a working channel), and providing an aspiration passage for collecting fluids (e.g., saline or other preparations).

[0006] In conventional endoscopes, the distal portion of the endoscope can be configured to support and orient a therapeutic device, such as by using an elevator. In some systems, two endoscopes can be configured to cooperate, with the first endoscope guiding the second endoscope inserted therein with the aid of an elevator. Such systems can be useful for guiding endoscopes to difficult-to-reach anatomical locations within the body. For example, some anatomical locations can only be accessed with an endoscope after insertion through a circuitous path. For example, a duodenoscope procedure (e.g., an endoscopic retrograde cholangiopancreatography (ERCP) procedure) involves the use of an auxiliary scope (also called a daughter scope or cholangioscope) that can be advanced through the working channel of the main scope (also called a mother scope or duodenoscope). Furthermore, another device, such as a tissue retrieval device used for biopsy, can be inserted into the auxiliary scope. Typically, the duodenoscope, auxiliary scope, and tissue retrieval device are progressively smaller because such scopes are configured in a telescoping arrangement. Typically, after each use, duodenoscopes, auxiliary scopes, and tissue retrieval devices are cleaned and sterilized for reuse. Thus, imaging and control systems, including light generators, image processing capabilities, and treatment functions, are typically configured for repeated use with the same or similar types of endoscopes and instruments. Summary of the Invention [Problem to be solved by the invention]

[0007] The present disclosure recognizes that problems to be solved in surgical systems include the need to adapt single-use endoscopes for use with existing imaging and control systems. For example, there has been a recent desire to utilize single-use endoscopes to eliminate the need to clean, sterilize, and reprocess reusable scopes. However, many capital equipment devices, such as light generators, image processing devices, 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 guides or light pipes, that transmit light generated by the imaging and control system to the distal end of the endoscope for use with the anatomical structure. Thus, an endoscope operator can control the imaging and illumination functions of the endoscope from the imaging and control system. Therefore, there is a need to produce an inexpensive single-use endoscope that is compatible with existing imaging and control systems. [Means for solving the problem]

[0008] The present disclosure can provide a solution to these and other problems by providing systems, devices, and methods related to adapters that can transmit lighting commands from an imaging and control system to an endoscope, particularly a single-use endoscope with an on-board light generator. It may be desirable to manufacture a single-use endoscope that includes a light generator, such as a light-emitting diode (LED), instead of a light transmitter. LED light generators can be less expensive than light transmitters, such as optical fibers. Furthermore, optical fibers are delicate and can break if mishandled. However, removing the light guide from the endoscope eliminates the imaging and control system's ability to control light output at the distal end of the endoscope. For example, commands input into the imaging and control system for the imaging and control system's light generator do not change the light generated by the endoscope's light generator because electronic signals from the imaging and control system's light generator are not communicated to the endoscope. In the present disclosure, an endoscope adapter can be configured to provide lighting commands to a light generator within the endoscope based on lighting 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 commands for the light generator within the endoscope. One or more sensors can sense parameters of the light generated by the imaging and control system and convert the sensed parameters into instructions for the endoscope's light generator to generate light having the same parameters. In certain examples, 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 endoscope's light generator. Additionally, 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 endoscope's light generator. In this manner, existing imaging and control systems and associated operating procedures can be used with endoscopes that have on-board light generators, including single-use endoscopes.

[0009] In one example, an adapter for an endoscope system includes a housing, a housing extending therethrough, Light guide element , Light guide element The endoscope may include a sensor disposed within the housing for receiving light waves emitted from the endoscope, a transducer connected to the sensor for converting the light waves into an electrical signal, the transducer including instructions for generating light using a light generator of the endoscope, and an electrical coupler accessible through the housing connected to the transducer and configured to transmit the electrical signal from the housing to the endoscope.

[0010] In another example, a surgical endoscopic system can include an imaging and control system including a light source having a socket; an endoscope including a shaft having a coupler at a proximal end and an imaging device at a distal end, a working channel extending at least partially through the shaft, and a light generator configured to emit light proximate the distal end; and an adapter configured to connect to the socket, the adapter including a light sensor configured to receive light waves from the light source when the adapter is connected to the socket, the socket configured to receive the coupler of the endoscope, and a converter configured to convert light intensity readings from the light sensor into instructions for operating the light generator.

[0011] In a further example, a method for communicating light control signals 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 with 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 through the adapter to the second light generator of the endoscope, wherein the light control signal is configured to instruct the second light generator of the endoscope to generate light of an intensity equivalent to that sensed by the sensor.

DETAILED DESCRIPTION OF THE INVENTION

[0013] 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 one 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 can be inserted into an anatomical region for imaging and / or provide passage for other devices, such as an auxiliary scope and a biopsy device or one or more therapeutic devices, for treatment of a disease state associated with the anatomical region. The endoscope 14 can advantageously interface and connect with the imaging and control system 12, such as via insertion into a socket 37 of a coupler section 36. In the illustrated example, the endoscope 14 comprises a duodenoscope, although other types of endoscopes can be used with the features and teachings of the present disclosure.

[0014] 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 .

[0015] 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 data input / output may be provided through an interface between the coupler section 36 and the 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 light conductor 39 ( FIG. 2 ) configured to receive light from a lens or bulb within the light source unit 22. The fluid source 24 may include a port for transmitting fluid to the endoscope 14. The fluid source 24 may include a pump and a tank of fluid 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 transferred to the endoscope 14 through the interface between the coupler section 36 and the socket 37. In an example, a fluid such as water can be input directly to the coupler section 36 without exiting the socket 37. The output unit 18, e.g., a touchscreen display, and the input unit 20, e.g., a keyboard, can be used by an operator of the endoscopic system 10 to control functions of the endoscopic system 10 and view the output of the endoscope 14. The control unit 16 can 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 can generate electrical outputs, acoustic outputs, fluid outputs, etc., for treating the anatomical region using, for example, cauterization, cutting, freezing, etc.

[0016] The endoscope 14 may include an insertion section 28, a function section 30, and a handle section 32, and 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 to connect the endoscope 14 to several 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 connected directly to the endoscope 14 without going through the control unit 16.

[0017] 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 manipulate the distal end through tortuous anatomical passageways (e.g., the stomach, duodenum, kidney, ureter, etc.). The insertion section 28 can also be elongated and can include one or more working channels (e.g., internal lumens) that can support the insertion of one or more therapeutic instruments of the functional section 30, such as an auxiliary scope. The working channels can extend between the handle section 32 and the functional section 30. Additional functionality, such as fluid passageways, guidewires, and pullwires, can also be provided by the insertion section 28 (e.g., via aspiration or irrigation passageways, etc.).

[0018] Handle section 32 can include a control knob 38 and a port 40A. Control knob 38 can be coupled to a pull wire or other actuation mechanism that extends through insertion section 28. Port 40A, as well as other ports, such as port 40B (FIG. 2), can be configured to couple various electrical cables, guide wires, auxiliary scopes, tissue collection devices, fluid tubing, etc. to handle section 32 for coupling with insertion section 28.

[0019] According to an embodiment, the imaging and control system 12 may be provided on a mobile platform (e.g., cart 41) with shelves for housing the light source unit 22, the suction pump 26, the image processing unit 42 (FIG. 2), etc. Alternatively, some components of the imaging and control system 12 shown in FIGS. 1 and 2 may be provided directly on the endoscope 14 to make the endoscope "self-contained."

[0020] The functional section 30 may include components for treating and diagnosing a patient's anatomy. The functional section 30 may include an imaging device, an illumination device (e.g., the distal end of an optical fiber), and an elevator. Operation of some or all aspects of the functional section 30 is typically performed by the imaging and control system 12.

[0021] 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 can include a control unit 16 that can include or be coupled to an image processing unit 42, a therapy generator 44, and a drive unit 46, as well as a light source unit 22, an input unit 20, and an output unit 18. A coupler section 36 can be connected to the control unit 16 to connect the endoscope 14 to several features of the control unit 16, such as the image processing unit 42 and the therapy generator 44. In an example, a plug portion 48 of the coupler section 36 can include leads 49 for connecting to wiring in a socket 37 that can connect to the light source unit 22, the image processing unit 42, and the therapy generator 44. In an example, the port 40A can be used to insert another instrument or device, such as a daughter or 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 without 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 toward the endoscope 14 or other devices extending therefrom. The light source unit 22 can include a light generator, such as a xenon bulb or a light-emitting diode. For example, the light source unit 22 can include multiple light generators to generate light with different characteristics, such as different colors.

[0022] The image processing unit 42 and the light source unit 22 can each interface with the endoscope 14 (e.g., at the function section 30) via a wired or wireless electrical connection. Thus, the imaging and control system 12 can illuminate an 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 for illuminating the anatomical region with light of a desired spectrum (e.g., broadband white light, narrowband imaging 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 a light source, video signals from an imaging system at the distal end, diagnostic and sensor signals from a diagnostic device, etc.).

[0023] 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 paths (e.g., air channels, irrigation channels, aspiration channels) and connectors (barbed fittings, fluid seals, valves, etc.). The fluid source 24 can be utilized as activation 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 International Publication No. WO 2011 / 140118 A1 to Frassica et al., entitled "Rotate-to-Advance Catheterization System," which is incorporated herein by reference in its entirety.

[0024] As described above, the coupler section 36 can be used in the endoscope 14 connected to the imaging and control system 12. The coupler section 36 can be used to communicate various functions between the endoscope 14 and the imaging and control system 12. In examples, the coupler section 36 can transmit communication signals, electronic signals, electrical signals, power signals, fluids including water and air, light waves, and the like. The coupler section 36 can comprise a portion of the endoscope 14 and can be configured for a particular configuration of the imaging and control system 12. For example, the coupler section 36 can be configured to transmit light generated by the light source unit 22 to the endoscope 14 using a light guide 39, as described with reference to FIG. 3. According to the present disclosure, a light processing adapter can be connected to the imaging and control system 12 to couple to an endoscope having a built-in or on-board light generator. Such a light processing adapter can convert light generated by the light source unit 22 into electronic instructions for operating the on-board light generator to replicate the light generated by the light source unit 22, as described with reference to FIG. 4.

[0025] FIG. 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, the scope cable 114 may comprise an example of the cable section 34 of FIG. 2, the scope handle 116 may comprise an example of the handle section 32 of FIG. 2, and the scope working shaft 118 may comprise an example of the insertion section 28 of FIG. 2. In an example, light guide connector 100 may include an example of socket 37 of Figure 1. Accordingly, scope cable 114 may include a coupler similar to coupler section 36 of Figure 1.

[0026] The light guide connector 100 can be used to transmit electronic signals and light waves between the imaging and control system 102 and the endoscope 104. In FIG. 3 , light waves can be represented by dashed lines and wired signals can be represented 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 operating various features of the endoscope 104, such as ablation, suturing, RF signal generation, cryogenic features, etc., can be transmitted from the controller 105 to the endoscope 104. Additionally, light waves from the light source 110 can be transmitted to the endoscope 104 via the light guide connector 100.

[0027] The light guide connector 100 may include a light guide 126 and electrical wiring 128. The endoscope 103 may include a light guide 130 and electrical wiring 132. The imaging and control system 102 may include a light guide 134 and control wiring 136. The light guide 126 of the light guide connector 100 may connect the light guide 130 of the endoscope 104 to the light source 110 via the light guide 134, and the electrical wiring 128 of the light guide connector 100 may connect the electrical wiring 132 of the endoscope 104 to the controller 105 via the control wiring 136.

[0028] 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 be passed through the scope working shaft 118, the scope handle 116, and the scope cable 114 via appropriate conductors in the electrical wiring 132 to electrical wiring 128 of the light guide connector 100. The electrical wiring 128 of the light guide connector 100 can include appropriate couplers for transmitting the electronic signals from the imaging device 120 to the imaging and control system 102 via control wiring 136. Thus, video processor 106 may receive electronic signals from imaging device 120, after appropriate processing, etc., for display on a video monitor, such as output unit 18 of Figure 1. Memory 108 may include various red, green, and blue image memories for processing signals generated by imaging device 120.

[0029] 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. In particular, control wiring 136, electrical wiring 128, and electrical wiring 132 can additionally be used to convey control signals for diagnostic and therapeutic functions of endoscope 104. For example, a user can input functional settings for endoscope 104 into controller 105, e.g., 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 with additional conductors or the same conductors that carry imaging signals, e.g., using lead 49 (FIG. 2).

[0030] Additionally, although not shown in FIG. 3, the light guide connector 100 may include appropriate tubing or tubing for transporting fluids, such as saline, irrigation fluid, air, insufflation gases, and other gases, to and from the endoscope 104.

[0031] 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 imaging and control system 102, such as the light source 110 or the input unit 20 (FIG. 1), can include control features such as buttons or knobs for starting and stopping the generation of light waves and controlling the intensity of the light waves. The imaging and control system 102 can additionally include 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 for the light transmitted to the light guide 124 of the endoscope 104 with the imaging and control system 102. 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 equals off), 2) the intensity setting 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 which of the filters 112 is applied to the output of the light source 110. Each of 1), 2), and 3) can be set by a user in controller 105 and can be represented as a characteristic of the light wave emitted from light source 110. Light conductor 126 of light guide connector 100 can include an appropriate coupler, conductor, or pipe for transmitting light waves from light conductor 134 of light source 110 to light guide 124. In this manner, light waves from light source 110 can travel through filter 112, light conductor 134 of imaging and control system 12, light conductor 126 of light guide connector 100, light conductor 130 of endoscope 104 (including light conductor 39 of FIG. 2), and light guide 124, thereby allowing the light waves to exit endoscope 14 and illuminate the anatomical structure into which endoscope 104 is inserted.

[0032] The light guide connector 100 configured in this manner can be configured, without modification, to relay signals and light waves between the imaging and control system 102 and the endoscope 104. In an example, the endoscope 104 can be specifically configured to operate 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 interrupting or introducing any 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 processor 106, and between the controller 105 and the endoscope 104 functions. Thus, the light guide connector 100 does not include any functionality 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 receive the output of imaging and control system 12 or that are not mechanically configured to mate with socket 37 are not interoperable or compatible with imaging and control system 12.

[0033] FIG. 4 is a block diagram illustrating an adapter 150 of the present disclosure for coupling the imaging and control system 102 of FIGS. 1 and 2 to an endoscope 152.

[0034] 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 described with reference to FIG. 3 to provide optical output on a light conductor 134 and to send and receive communication signals via control wiring 136.

[0035] Endoscope 152 can 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 can be configured similarly to endoscope 104 of FIG. 3, except that endoscope 152 can include light generator 166 rather than extending through light conductor 130 as in endoscope 104. In an example, scope cable 154 can be configured similarly to cable section 34 of FIG. 2, scope handle 156 can be configured similarly to handle section 32 of FIG. 2, and scope working shaft 158 ​​can be configured similarly to insertion section 28 of FIG. 2, including imaging device 160 instead of a proximal light conductor. In an example, light guide connector 100 can include an example of socket 37 of FIG. 1.

[0036] The adapter 150 can be used to transmit information from the light guide connector 100 to the endoscope 152. The adapter 150 can be configured to be inserted into the socket 37 (FIG. 1) and receive light from the light source unit 22, control signals from the control unit 16, and various air sources. The light guide connector 100 can be used to transmit electronic signals and light waves between the imaging and control system 102 and the adapter 150. In FIG. 4, light waves can be represented by dashed lines, and wired signals can be represented 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. In addition, the adapter 150 can transmit electronic signals from the controller 105 and the light guide connector 100 to the endoscope 152. The adapter 150 can receive light waves generated by the light source 110 from the light guide connector 100 and convert such light waves into a combined signal wiring 170 for transmission to the light generator 166. The light generator 166 may comprise a light source configured to output light waves. In an example, the light generator 166 may comprise a light emitting diode (LED). In an additional example, the light generator 166 may be configured to generate light of different colors.

[0037] The adapter 150 can include a combined signal wiring 170 that can extend through the endoscope 152. The combined signal wiring 170 can branch into an optical signal wiring 170A for communicating with the light generator 166 and an imaging signal wiring 170B for communicating with the imaging device 160. The imaging and control system 102 can include light conductors 134 and control wiring 136. The light conductors 126 and electrical wiring 128 of the light guide connector 100 can be connected to the adapter 150, which can transmit the combined signal wiring 170 to the light generator 166 and the imaging device 160.

[0038] 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 be passed 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 via appropriate conductors in the combined signal wiring 170. The electrical wiring 128 of the light guide connector 100 can include appropriate couplers for transmitting the electronic signals from the adapter 150 to the imaging and control system 102 via the control wiring 136. Thus, video processor 106 may receive, after appropriate filtering, etc., electronic signals from imaging device 160 for display on a video monitor, such as output unit 18 of FIG.

[0039] The light source 110 can control the intensity and type of light generated by the imaging and control system 102, as described above. 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 a button or knob, to start and stop the generation of light waves and control the intensity of the light waves, etc., to control 1) the on / off of the light source 110, 2) the intensity of the light from the light source 110, and 3) the color of the light as determined by the filter 112. The light conductor 126 of the light guide connector 100 can include appropriate couplers, conductors, or pipes for transmitting light waves from the light conductor 134 of the light source 110 to the adapter 150. The adapter 150 can receive light waves from the light conductor 134 and convert sensed characteristics of the light waves, such as on / off, intensity, and color, into electronic control signals for the light generator 166. The adapter 150 can include appropriate sensors and circuitry for converting light waves into electronic control signals, as described with reference to FIGS. 5-15. In this manner, light waves from light source 110 can travel through filter 112, light conductor 126 of light guide connector 100, and to adapter 150, which can then send a light generation signal along combined signal wiring 170 to light generator 166, which can then output light to light guide 164, thereby allowing light waves to exit endoscope 152 and illuminate the anatomical structure into which endoscope 152 is inserted. Thus, when an operator of imaging and control system 102 requests light, e.g., commands light source 110 to be turned on, light generator 166 can be commanded to generate light waves of an intensity and color comparable to the light waves exiting light source 110.

[0040] The adapter 150 configured in this manner can be configured to relay signals between the imaging and control system 102 and the endoscope 152 using conversion, modification, or interpolation. The endoscope 152 need not be specifically designed to operate with the imaging and control system 102 and can include any type of light generator 166 and coupler section. In an example, the endoscope 152 can be adapted to operate with the imaging and control system 102 using 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 1), 2), and 3) control inputs input to the light generator 166 at the controller 105. In addition to optical signals, e.g., light waves, and imaging signals, e.g., electronic communication signals, the adapter 150 can relay other types of data, e.g., control signals, and various fluids, such as water and air, between the light guide connector 100 and the endoscope 152. The adapter 150 may comprise reusable parts that are easily cleaned and sterilized, while the endoscope 152 may be configured as a disposable scope that does not need to be cleaned or sterilized.

[0041] Figure 5 is a rear perspective view of adapter 200 of the present disclosure, showing main housing 202 and plug component 204. Figure 6 is a front perspective view of adapter 200 of Figure 5, showing socket component 206 for receiving an endoscope plug. Adapter 200 may comprise an example of adapter 150 of Figure 4. Figures 5 and 6 will be described simultaneously.

[0042] The plug component 204 can include an air coupler 208, a light guide assembly 210, and electrical leads 212. The air coupler 208 and light guide assembly 210 can extend from an end face 214 of the plug component 204. The electrical leads 212 can extend from a shoulder or corner of the plug component 204. The air coupler 208 and light guide assembly 210 can be coupled to the light guide connector 100 ( FIG. 3 ) or directly to the light source unit 22 ( FIG. 1 ) or another component of the imaging and control system 12. The plug component 204 can be inserted into a receptacle 216 of the main housing 202. The main housing 202 can include lugs 218A and 218B that can be coupled to a receptacle, such as socket 37 ( FIG. 1 ), of the light guide connector 100 or the light source unit 22 via a twist-lock or push-pull operation. Main housing 202 may include other features such as pads 220A and 220B to provide ergonomic engagement with the user's fingers.

[0043] The adapter 200 can be configured to receive light waves at a light conductor assembly 210, receive air at an air coupler 208, and receive control signals at electrical leads 212 and 214. In an example, the plug component 204 can be configured similar to the plug portion 48 of the coupler section 36 (FIG. 2), and the electrical lead 212 can operate similar to the lead 49. Thus, control signals generated by the imaging and control system 12 (FIGS. 1 and 2) can be transmitted to the adapter 200. The light conductor assembly 210 can be configured similar to the light conductor 39 (FIG. 2). This allows light output by the light source unit 22 to be transmitted to the adapter 200.

[0044] Socket component 206 may include an opening 222 for receiving an endoscope plug, such as a plug connected to composite signal wiring 170 (FIG. 4). Opening 222 may include a pneumatic coupler 230 (FIG. 8) and an electrical coupler 232 (FIG. 8) for communicating with endoscope 152 (FIG. 4). As described with reference to FIGS. 7 and 8, adapter 200 may allow air and control signals to pass through main housing 202 and plug component 204 via fluid coupler 230 and electrical coupler 232.

[0045] Figure 7 is a rear end view of the adapter 200 of Figures 5 and 6, showing the light pipe assembly 210 and pneumatic coupler 208. Figure 8 is a front end view of the adapter 200 of Figures 5 and 6, showing the pneumatic coupler 230, the electrical coupler 232, and the alignment posts 234A and 234B. Figures 7 and 8 will be discussed simultaneously.

[0046] The plug component 204 can be inserted into a socket 37 (FIG. 1) of the light source unit 22. Once inserted, the electrical leads 212 and 214 can connect to electrical contacts in the socket 37 to enable transmission of electrical signals from the imaging and control system 12, such as from the control unit 16 and the light source unit 22.

[0047] The opening 222 allows the plug of the endoscope 152 (FIG. 4) to be inserted. The opening 222 can have an irregular shape, such as a generally square shape with one rounded side, to facilitate one-way assembly with the endoscope plug. Alignment posts 234A and 234B can be disposed in the opening 222 to facilitate coupling with the endoscope plug. For example, the alignment posts 234A and 234B can comprise cylindrical posts against which a cylindrical socket of the endoscope plug can slide to facilitate alignment. Additionally, the alignment posts 234A and 234B can relieve stress on the fluid coupler 230 and the electrical coupler 232. In an additional example, the alignment posts 234A and 234B can be spring loaded to facilitate ejection of the adapter 200. For example, the 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 ejection of the adapter 200 when pulled by an operator or user.

[0048] Air lines can be connected to the air coupler 208 and the air coupler 230. An air line 242 (FIGS. 10 and 11) can extend between the air coupler 208 and the air coupler 230 to allow air to pass through the adapter 200. For example, the air coupler 208 and the air coupler 230 can be connected to air, carbon dioxide, saline, water, and other fluids to perform various functions, including insufflation. In examples, the air coupler 208 and the air coupler 230 can comprise hose couplers or hose fittings, with or without valves. In examples, the adapter 200 can be configured to simply allow air to pass through the main housing 202 and the plug component 204 without interference, regulation, or control. However, in some examples, the adapter 200 can be configured to actively control air flow through the main housing 202 and the plug component 204 based on electronic signals received from the control unit 16 (FIG. 1) or other source, such as by including an electronically controlled valve.

[0049] The light conductor assembly 210 can be configured to receive light waves from a light source. In particular, an end of the light conductor assembly 210 can face the output of a bulb or LED in the light source unit 22. The light conductor assembly 210 can extend into the plug component 204 and emit light waves onto the sensor package 245 ( FIG. 9 ). As described in more detail below, electronics connected to the sensor package 245 can convert the light waves into instructions for the light generator 166 ( FIG. 4 ), which can be transmitted through the electrical coupler 232. In an example, the light conductor assembly 210 can include a light conductor 240 disposed in a sheath 241. In an example, the light conductor 240 can comprise a light pipe or a bundle of optical fibers. For example, the light conductor 39 ( FIG. 2 ) of the endoscope 14 can include an optical fiber bundle, as the light conductor 39 can comprise the proximal-most end of a bundle of optical fibers extending through the cable section 34 and the insertion section 28. Therefore, to facilitate flexibility, it is desirable to fabricate the light conductor 39 from multiple optical fibers. However, the light guide 240 may comprise a light pipe, which may comprise a single-piece light guide having a much larger diameter than an individual optical fiber. Thus, the light guide 240 may be stiffer, more robust, such as by being more resistant to heat. Further description of the light guide assembly 210 is provided with reference to FIG. 13.

[0050] 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. In addition, Figure 9 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 light pipe 240, and the air line 242. Figures 9 and 10 will be discussed simultaneously.

[0051] The light conductor 240 can be connected to a light conductor assembly 210 extending from the plug component 204. The light conductor can direct light to a sensor package 245. The air line 242 can be connected to the air coupler 230 and the air coupler 208 (FIGS. 5 and 7). The light board 244 can be connected to a control board 246 of the plug component 204 via fasteners 248 and posts 250. The control board 246 can be connected to prongs 254 of the electrical leads 212. The control board 246 can be connected to a communication board 252 via a connector 253, which can be attached to a board 255. The connector 253 can be connected to the communication board 252 via wiring 256 (FIG. 11). The light board 244 can be connected to the communication board 252 via wiring 258 (FIG. 11). The communication board 252 can be connected to the electrical coupler 232 for transmitting control signals and light-generating signals to the endoscope 152 (FIG. 4). Thus, when plug component 204 is inserted into socket 37 (FIG. 1), electrical leads 212 can be positioned to communicate with endoscope 152 via prongs 254, communication board 252, and electrical coupler 232. Similarly, when plug component 204 is inserted into socket 37, air line 242 can be positioned to communicate with endoscope 152 through air line 242, air coupler 208, and air coupler 230. Additionally, light pipe assembly 210 can be positioned in alignment with sensor package 245.

[0052] FIG. 11 is a cross-sectional view through the adapter 200 of FIG. 10, showing the air line 242 passing through the adapter 200 and sensor package 245 positioned adjacent to the light guide 240.

[0053] Air line 242 may comprise a conduit coupled to air coupler 208 and air coupler 230. In an example, air line 242 may comprise a rubber or plastic pipe or tubing. Air line 242 may be connected to appropriate fittings on air coupler 208 and air coupler 230 to provide a leak-proof passage through adapter 200. For example, air coupler 208 and air coupler 230 may include barbed fittings into which air line 242 may mate. Air coupler 208 may include a male protrusion that may mate with a mating female receptacle on socket 37 ( FIG. 1 ). Air coupler 230 may include a female receptacle that may receive a mating male protrusion on a coupler 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. The air line 242 may extend unsupported through the adapter 200 between the air coupler 208 and the air coupler 230. Accordingly, the control board 246 of the support bracket 203 may include suitable openings to allow the air line 242 to extend therethrough.

[0054] Figure 12 is a cross-sectional view through the adapter 200 of Figure 10, showing a light conductor 240 directed towards a sensor package 245 mounted on a light board 244 connected to an electrical coupler 232. Figure 12 will be described with further reference to Figure 11.

[0055] The light conductor assembly 210 can be attached to the socket component 206. Specifically, the sheath 241 can be inserted into a receptacle 259 on the end face 214 of the socket component 206. The distal end of the light conductor 240 can protrude through the light board 244 and the support bracket 203 so as to be disposed within the main housing 202 proximate to the sensor package 245. The light board 244 can be attached to the support bracket 203 via fasteners 248. The light board 244 can be disposed to communicate with a communication board 252 via an appropriate connection. In an example, wiring 258 can connect the light board 244 and the communication board 252. In another example, the light 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 described with reference to FIG. 14 , the sensor package 245 can include one or more light sensors for interpreting various characteristics of the light waves exiting the light conductor 240. The sensor package 245 or other suitable electronics can convert the output of the light sensors into instructions ( FIG. 4 ) for operating the light generator 66. The instructions for operating the light generator 66, 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 input / output devices configured to send and receive electronic communication signals as well as power, e.g., 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 various prongs 254 from the sensor package 245 and the control unit 16 can be passed to various components ( FIG. 4 ) of the endoscope 152.

[0056] Figure 13 is a cross-sectional view of the adapter 200 of Figure 10 showing the light pipe assembly 210. The light pipe assembly 210 can include a light pipe 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.

[0057] The proximal end of the light guide 240 may include a surface 268. The surface 268 may be positioned to receive light waves generated by the light source unit 22 exiting the socket 37 ( FIG. 1 ). The light guide 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 light guide 240. The filters 264A and 264B may comprise polarizing films at an angle to each other to reduce the intensity of light transmitted into the light guide 240. In an example, the intensity of light entering the light guide 240 may be reduced as a safety feature to limit the temperature of the light reaching the sensor package 245. Additionally, very high light intensities may electronically overwhelm the sensors in the sensor package 245. Sensor package 245 can be configured to have a memory in which information regarding the amount of intensity reduction provided by filters 264A and 264B is stored so that instructions for operating light generator 166 (FIG. 4) can be adjusted accordingly. Further description of the operation of sensor package 245 is provided with reference to FIGS. 14 and 15.

[0058] An end cap 260 can be placed around filters 264A and 264B to secure filters 264A and 264B to surface 268 of light guide 240. End cap 260 can include a lens 262 and a fitting 270. Fitting 270 can include a retention device for holding filters 264A and 264B relative to light guide 240. End cap 260 can then be placed over fitting 270 to hold filters 264A and 264B in place. Lens 262 can include a piece of glass or crystal that allows light waves to pass through without alteration. Lens 262 can protect filters 264A and 264B.

[0059] 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 processor 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.

[0060] The air passageway 310 can be configured similarly to the air coupler 208, the air line 242, and the air coupler 230. The air passageway 310 can be configured as a pipe or tube that allows fluids such as air, gas, and water to pass through the adapter 300. The ends of the air passageway 310 can be provided with appropriate male or female fittings for connecting to an imaging control system and an endoscope.

[0061] I / O device 306 can be configured as or in communication with electrical leads 212, prongs 254, and control board 246. I / O device 306 can be configured to relay electronic communication signals to and from adapter 300 for communication with the imaging and control system. I / O device 308 can be configured as electrical coupler 232. I / O device 306 can be configured to relay electronic communication signals to and from adapter 300 for communication with the light-generating endoscope.

[0062] In examples, I / O device 306 and I / O device 308 can communicate using wireless communication signals such as Bluetooth, WiFi, Zigbee, infrared (IR), near field communication (NFC), 3GPP, or other technologies. In examples, I / O device 306 and I / O device 308 can have a wired connection or can include a port for accepting wires for a wired connection. In examples, I / O device 306 and I / O device 308 can communicate using one or more of the IEEE 802.15.6-2012 protocol, the MICS protocol, and the MBAN protocol. In examples, I / O device 306 and I / O device 308 can have a port such as a serial (e.g., universal serial bus (USB)) port, a parallel port, or another wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate with or control one or more features of the imaging and control system and the endoscope.

[0063] Filter 320 can be configured as filters 264A and 264B. In an example, filter 320 can comprise an absorptive filter that can absorb wavelengths of certain colors and pass wavelengths of other colors. In an example, filter 320 can comprise an interference filter that reflects wavelengths in certain spectral bands and transmits wavelengths in other spectral bands. In an example, filter 320 can comprise a pair of polarizer filters that are rotationally offset to pass light waves of certain polarizations and block light waves of other polarizations.

[0064] The light pipe 322 can be configured as a light guide 240. The light pipe 322 can comprise a single or monolithic component fabricated from optical acrylic or polycarbonate, or other materials. Alternatively, the light pipe 322 can be replaced with a bundle of optical fibers made from silica, plastic, or other materials. The light pipe 322 can extend between the filter 320 and sensors 324A and 324B. Thus, light exiting the filter 320 can enter one end face of the light pipe 322, and light exiting the opposite end of the light pipe 322 can direct light waves to sensors 324A and 324B.

[0065] 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-light current sensor, a light-to-analog-to-voltage sensor, and a light-to-digital sensor.

[0066] Circuit board 314 may comprise structural components for electrically and structurally coupling the electrical components of adapter 300. For example, circuit board 314 may comprise a silicon wafer or chip with electrical couplings attached for electronic coupling of processor 316, memory 318, sensors 324A and 324B, etc. Circuit board 314 coupled to processor 316, memory 318, and sensors 324A and 324B may operate as a transducer for converting light waves into electronic signals as described herein.

[0067] Processor 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. Processor 316 may execute instructions stored in memory 318 to operate components of adapter 300, such as sensors 324A and 324B. In an example, a processor and memory are not required and adapter 300 may operate as a simple integrated circuit where the outputs of sensors 324A and 324B can be transmitted directly by I / O devices 306 and 308.

[0068] Memory 318 may include any suitable storage device, such as non-volatile computer-readable memory, magnetic memory, flash memory, volatile memory, programmable read-only memory, etc. Memory 318 may include instructions stored therein for processor 316 to control operation of 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 comparison with data from sensors 324A and 324B, such as a look-up table for correlating sensed light intensity with respect to power input to light generator 166 (FIG. 4), as well as other information that 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 one example, memory 318 may include a look-up table having light intensities from zero to maximum output of light source 110 (FIG. 4) correlated to current input to light generator 166 (FIG. 4) from zero to maximum input to light generator 166.

[0069] In an 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 apply to the lookup table described above. For example, the processor may determine that filter 320 reduces the output of light source 110 by 50%, so that the output of sensors 324A and 324B may be increased by 50% before looking up the appropriate current to generate to operate light generator 166.

[0070] In a further example, the memory 318 may include instructions that enable the processor 316 to perform compensation for the light source 110. For example, various light sources, such as xenon light bulbs, are known to dim over time, e.g., emit less light than desired. Thus, an imaging and control system requesting a particular light intensity output may result in the light source outputting light having, for example, 95% of the requested intensity. The light processing adapter of the present disclosure can 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 output to the light source 110 upon startup. The light processing adapter 300 may have stored in the memory 318 appropriate, e.g., intended undim, 0% and 100% intensity outputs for a particular model of the imaging and control system 102. Thus, the processor 316 can determine that the light source 110 is only outputting 95% of the output requested by the imaging and control system 102 and can appropriately upscale the output of the light generator 166 so that the output of the light generator 166 matches the light intensity requested by the imaging and control system 102, even though the light source 110 is not providing the requested light intensity.

[0071] 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 a light control signal for the light generator 166 of the endoscope 152.

[0072] In operation 402, light can be generated using a first light generator of the imaging and control system. For example, the light can be generated using the light source 110 of the imaging and control system 102 (FIG. 4). A user can input on / off, intensity, and color settings in a user interface. For example, a user can input on / off, intensity, and color settings for the light source 110 using the output unit 18 and the input unit 20 (FIG. 1).

[0073] In operation 404, light from a first light generator, for example, light source 110, can be received by adapter 300, which is connected to imaging and control system 102 (FIG. 4). Light waves from light source 110 can enter light conductor assembly 210 of adapter 300. Light conductor assembly 210 can be positioned opposite a light bulb or light emitting diode in light source 110 when adapter 300 is inserted into socket 37 (FIG. 1).

[0074] At operation 406, a property of the light can be sensed using a sensor in the adapter. For example, a first sensor 324A (FIG. 14) can be used to sense the intensity of the light from the light source 110. Additionally, in an example, a second sensor 324B (FIG. 14) can be used to sense the color of the light from the light source 110. Light waves can exit the light pipe assembly 210 and be incident on the first sensor 324A and the second sensor 324B of the sensor package 245. The light waves can excite appropriate elements in the first sensor 324A and the second sensor 324B to generate electrical signals.

[0075] At operation 408, the light characteristics sensed by the sensors can be converted into control signals 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 an instruction for generating light using the light generator 166 (FIG. 4) of the endoscope 152 (FIG. 4) at the same intensity. Additionally, in an example, the color of light sensed by the second sensor 324B can be converted into an instruction for generating light using the light generator 166 of the same color.

[0076] In an example, the processor 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 to the current input to the light source 110. Thus, the current output from the first sensor 324A may be scaled by the processor 316 as a control signal for the light generator 166. The processor 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 supplied to the light generator 166 to generate 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 generator 166. In an example, processor 316 may receive a signal from imaging and control system 12 providing identification information of light source 110, e.g., manufacturer, light type, bulb type, color type, LED type, etc., as well as an identification signal from endoscope 152 (FIG. 4) providing identification information of light generator 166, e.g., manufacturer, light type, bulb type, color type, LED type, etc. Accordingly, processor 316 may consult a lookup table having appropriate information for converting the determined light output of the imaging and control system into the determined control input to light generator 166. Additionally, as described herein, processor 316 may adjust the output of sensors 324A and 324B to correspond to the light intensity filtering conducted within adapter 300 using filter 320, as well as to provide light intensity compensation for dimming of the output of light source 110 resulting from long-term use.

[0077] At operation 410, the light control signal can be transmitted through the adapter to a second light generator of the endoscope. For example, the light control signal generated by the processor 316 can be transmitted to the light generator 166 of the endoscope 152 via the combined signal line 170 and the light signal line 170A. The light generator 166 can generate light waves having an intensity based on the received output of the adapter 300. Furthermore, the light generator 166 can generate light waves of a color required by the adapter 300. Thus, the light output of the light generator 166 can match the output of the light source 110 in intensity and color. The light generator 166 can then emit light waves that can be irradiated onto tissue, such as using the light guide 164 (FIG. 4).
