Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an endoscope. Background Art

[0002] Endoscopes are commonly used medical devices that can directly access the body's natural channels for inspection, providing doctors with sufficient diagnostic information for treating diseases. Disposable or single-use endoscopes can reduce the risk of cross-contamination and hospital-acquired diseases. However, these disposable or single-use endoscopes require the entire endoscope to be discarded, increasing medical costs. To reduce medical costs, these endoscopes often require low-cost components, making it impossible to use high-specification components in disposable or single-use endoscopes, significantly compromising product functionality. Summary of the Invention

[0003] To solve the above problems, an object of the present invention is to provide an endoscope, comprising a secondary throw part, a reuse part and a display assembly, the secondary throw part comprising a handle assembly and an insertion assembly, the handle assembly comprising a first connector, a accommodating cavity, a first shell and a second shell, the first shell forming a handle grip, an opening of the accommodating cavity being provided on the side of the first shell, the reuse part being detachably installed in the accommodating cavity or removed from the accommodating cavity, the second shell covering the opening of the accommodating cavity, the reuse part comprising a control assembly, a drive assembly and a second connector, and when the reuse part is installed in the accommodating cavity, the first connector and the second connector are connected.

[0004] In some embodiments, the display assembly includes a signal conversion unit, a display, and a mainboard.

[0005] In some embodiments, the multiplexing section further includes a signal conversion unit, and the display assembly includes a display and a mainboard.

[0006] In some embodiments, the multiplexing portion and the display assembly are integrated.

[0007] In some embodiments, the multiplexing portion and the display assembly are transmitted via a first cable, which extends in a direction orthogonal to the gripping direction of the handle gripping portion to prevent the user from touching the cable.

[0008] In some embodiments, the contact impedance of the first connector and the second connector is less than 30 milliohms.

[0009] In some embodiments, the length of the second connector is 30 mm to 80 mm.

[0010] In some embodiments, the first connector and the second connector adopt a pin plug-in type, a contact method of a center terminal and a spring or a gold finger.

[0011] In some embodiments, the multiplexing unit and the display assembly are wirelessly transmitted. The second housing can accommodate both wireless and wired versions.

[0012] In some embodiments, when the reusing portion is installed in the accommodating cavity, the transmission assembly and the driving assembly are connected.

[0013] An endoscope provided by an embodiment of the present invention reduces the risk of cross-contamination and hospital-acquired diseases by combining a disposable unit with a reusable unit. By recycling and reusing the reusable unit, high-specification connectors, motors, encoders, signal conversion units, and other components can be used, improving the performance of the endoscope while reducing its cost. An opening for the accommodating cavity is provided in the first housing in the gripping direction to increase the connection space between the disposable unit and the reusable unit, adapting to different connection methods and ensuring the continuity and uninterrupted nature of the video signal.

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is intended only to enable those skilled in the art to better understand and implement the subject matter described herein, and is not intended to limit the scope of protection, applicability, or examples set forth in the claims. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present invention. Various examples may omit, replace, or add various processes or components as needed. For example, the described method may be performed in an order different from the described order, and various steps may be added, omitted, or combined. In addition, features described relative to some examples may also be combined in other examples.

[0031] Example 1:

[0032] Reference Figure 1-5 , an endoscope in embodiment 1 of the present invention is given, and the specific structure and workflow of the system are described in detail below.

[0033] An endoscope includes a disposable part 1, a reuse part 2 and a display component 3, the disposable part 1 includes a handle component 11 and an insertion component 12, the handle component 11 includes a first connector 112, a accommodating cavity 113, a first shell 114, a second shell 115 and a transmission component 116, the first shell 114 forms a handle grip, an opening of the accommodating cavity 113 is provided on the side of the first shell 114, the reuse part 2 can be detachably installed in the accommodating cavity 113 or removed from the accommodating cavity 113, the second shell 115 covers the opening of the accommodating cavity 113, the reuse part 2 includes a control component 21, a drive component 22 and a second connector 23, when the reuse part 2 is installed in the accommodating cavity 113, the first connector 112 and the second connector 23 are connected.

[0034] The multiplexing part 2 encapsulates the control component 21, the drive component 22 and the second connector 23 into a box body, the drive component 22 and the second connector 23 partially extend outside the box body, and the first connector 112 and the transmission component 116 partially extend into the accommodating cavity 113, so as to facilitate the communication between the first connector 112 and the second connector 23, and the connection between the drive component 22 and the transmission component 116.

[0035] A first cable 24 is provided at the bottom end of the multiplexing section 2, and the multiplexing section 2 and the display assembly 3 are transmitted through the first cable 24. The first cable 24 extends downward along the direction z orthogonal to the handle holding direction w, and the second shell 115 reserves an extension hole for the first cable 24 when covering the opening of the accommodating cavity 113. The display assembly 3 includes a signal conversion unit 31, a display 32 and a mainboard 33. The display assembly 3 is a terminal desktop, which has HDMI, DVI and other ports to meet the connection between the multiplexing section 2 and the display assembly 3. The entire product is powered by the terminal desktop to maintain the power supply and operation of the entire system.

[0036] The insert assembly 12 is provided with a lens module and a light. These are connected to the signal conversion unit 31 via the first connector 112, the second connector 23, and cables. The lens module and light transmit signals to the signal conversion unit 31, which then processes the signals and transmits them to the mainboard 33 for display on the display 32. Because the signal conversion unit 31 is located close to the main chip of the mainboard 33, the impact of transmission distance is reduced, which helps improve image quality.

[0037] The handle assembly 11 also includes a control switch 111, which includes a motor limit switch, a motor control switch, and a photo and recording switch. The signal of the control switch 111 is input into the control assembly 21 through the first connector 112 and the second connector 23. The control assembly 21 includes a control signal board.

[0038] When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is connected to the driving assembly 22. Specifically, the driving assembly 22 includes a motor 221 and a second transmission gear 222. An encoder is provided on the motor, and the signal is input to the control signal board through a cable connection. The transmission assembly 116 is a first transmission gear, which is engaged with the insertion assembly 12. When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is engaged with the second transmission gear 222. The motor 221 can drive the insertion assembly 12 through the transmission assembly 116 and the second transmission gear 222.

[0039] The contact impedance of the first connector 112 and the second connector 23 is required to be lower than 30 milliohms to ensure the continuity and uninterruptedness of the video signal. The larger the docking contact area between the first connector 112 and the second connector 23, the stronger the stability of the video signal. The length of the second connector 23 is 30 mm to 80 mm. In the present invention, an opening of the accommodating cavity 113 is provided in the first shell 114 in the gripping direction w, that is, the accommodating cavity 113 is provided on the side of the handle formed by the first shell 114. If the opening of the accommodating cavity 113 is provided at the end of the handle, in order to facilitate the hand to grip the handle, the opening at the end of the handle is inevitably limited by the size of the hand. Therefore, compared with the opening of the accommodating cavity 113 provided at the end of the handle, the design of the present invention can ensure that the accommodating cavity 113 can provide sufficient space to provide sufficient contact area for the first connector 112 and the second connector 23, so as to facilitate the plugging and unplugging of the multiplexing part 2 along the w direction.

[0040] like Figure 9 As shown, in this embodiment, the first connector 112 and the second connector 23 utilize a pin-type contact method. Their surfaces are gold-plated with at least 10U, and the spacing between each pin is 2.54mm. Using 20 pins arranged in a 2x10 pattern, the distance between pins is 25mm. Adding the space required for the fixed portion, the length of the multiplexing unit 2 is approximately 35mm. This pin-type contact method has a large contact area, good transmission efficiency, and easy impedance control. Other embodiments may also utilize this pin-type contact method.

[0041] During mass production, disposable unit 1 is packaged in a sterilization box to meet the sterility requirements of the operating room. During operating room procedures, doctors wear sterile gloves and the instruments they come into contact with must meet sterility standards. This means that any area the gloves touch must be sterile, otherwise, postoperative infection could occur. The reusable unit 2 is designed to be recycled and reused, and even with rigorous disinfection measures, it cannot achieve the same sterility level as disposable unit 1. Therefore, sterility stability cannot be guaranteed during use.

[0042] During use, the operator installs the reusable part 2 in the accommodating cavity 113, and attaches the second shell 115 to the first shell 114 to cover the opening of the accommodating cavity 113, seals the reusable part 2 in the handle assembly 11, and seals the disposable part 1 in the accommodating cavity 113 of the first shell 114 through the second shell 115, to prevent the doctor from touching the reusable part 2 during use of the instrument to meet the sterility requirements. The doctor wears sterile gloves to hold the handle formed by the first shell 114. The outer shape area of the handle is sterile. At the same time, the first cable 24 is drooped so as not to touch the gloves, ensuring safety during the entire operation. After use, the operator opens the second shell 115, takes out the reusable part 2 for recycling and disinfection, and discards the disposable part 1.

[0043] Example 2:

[0044] Reference Figure 6 , an endoscope in embodiment 2 of the present invention is given, and the specific structure and workflow of the system are described in detail below.

[0045] An endoscope includes a disposable part 1, a reuse part 2 and a display component 3, the disposable part 1 includes a handle component 11 and an insertion component 12, the handle component 11 includes a first connector 112, a accommodating cavity 113, a first shell 114, a second shell 115 and a transmission component 116, the first shell 114 forms a handle grip, an opening of the accommodating cavity 113 is provided on the side of the first shell 114, the reuse part 2 can be detachably installed in the accommodating cavity 113 or removed from the accommodating cavity 113, the second shell 115 covers the opening of the accommodating cavity 113, the reuse part 2 includes a control component 21, a drive component 22 and a second connector 23, when the reuse part 2 is installed in the accommodating cavity 113, the first connector 112 and the second connector 23 are connected.

[0046] The multiplexing part 2 encapsulates the control component 21, the drive component 22 and the second connector 23 into a box body, the drive component 22 and the second connector 23 partially extend outside the box body, and the first connector 112 and the transmission component 116 partially extend into the accommodating cavity 113, so as to facilitate the communication between the first connector 112 and the second connector 23, and the connection between the drive component 22 and the transmission component 116.

[0047] A first cable 24 is provided at the bottom end of the multiplexing part 2, and the multiplexing part 2 and the display component 3 are transmitted through the first cable 24. The first cable 24 extends downward in a direction perpendicular to the handle holding direction, and the second shell 115 reserves an extension hole for the first cable 24 when covering the opening of the accommodating cavity 113. The multiplexing part 2 also includes a signal conversion unit 31, and the multiplexing part 2 is connected to the display component 3, the display component 3 display 32 and the mainboard 33. The display component 3 is a terminal desktop, and the terminal desktop has HDMI, DVI and other ports, which can meet the connection between the multiplexing part 2 and the display component 3. The entire product is powered by the terminal desktop to maintain the power supply and operation of the entire system.

[0048] The insertion assembly 12 is provided with a lens module and a light. The lens module and the light are connected to the signal conversion unit 31 via the first connector 112 and the second connector 23 and cables, and transmit signals to the signal conversion unit 31. The signal conversion unit 31 processes the signals and then transmits them to the mainboard 33 for display via the display 32.

[0049] Reference Figure 6 The difference between the second embodiment and the first embodiment is that the signal conversion unit 31 is set in the multiplexing part 2, which can ensure that the signal input from the lens module to the signal conversion unit 31 is more stable.

[0050] The handle assembly 11 also includes a control switch 111, which includes a motor limit switch, a motor control switch, and a photo and recording switch. The signal of the control switch 111 is input into the control assembly 21 through the first connector 112 and the second connector 23. The control assembly 21 includes a control signal board.

[0051] When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is connected to the driving assembly 22. Specifically, the driving assembly 22 includes a motor 221 and a second transmission gear 222. An encoder is provided on the motor, and the signal is input to the control signal board through a cable connection. The transmission assembly 116 is a first transmission gear, which is engaged with the insertion assembly 12. When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is engaged with the second transmission gear 222. The motor 221 can drive the insertion assembly 12 through the transmission assembly 116 and the second transmission gear 222.

[0052] The contact impedance of the first connector 112 and the second connector 23 is required to be less than 30 milliohms to ensure the continuity and uninterrupted performance of the video signal. Figure 10 As shown, the first connector 112 and the second connector 23 utilize a central terminal and spring contact mechanism. The central terminal has a significant raised height, allowing the spring to effectively compress the terminal. This approach minimizes space and achieves low impedance. Both the central terminal and spring are made of brass with a 10U gold plating, achieving an impedance below 30 milliohms. Other embodiments may also utilize a central terminal and spring contact mechanism.

[0053] During mass production, the disposable part 1 is packaged in a sterilization box to meet the sterility requirements of the operating room. During use, the disposable part 1 and the reusable part 2 can be fixed to the accommodating cavity 113 through a movable mechanism connection method such as a snap, a pressure block, etc., ensuring that the exposed transmission gears between the two are tightly fixed, and the first connector 112 and the second connector 23 are plugged in. After the fixation is completed, the second shell 115 is installed on the first shell 114 to form a complete whole. During use, the operator cannot touch the reusable part 2 at all.

[0054] During use, the operator installs the reusable part 2 in the accommodating cavity 113, and attaches the second shell 115 to the first shell 114 to cover the opening of the accommodating cavity 113, seals the reusable part 2 in the handle assembly 11, and seals the disposable part 1 in the accommodating cavity 113 of the first shell 114 through the second shell 115, to prevent the doctor from touching the reusable part 2 during use of the instrument to meet the sterility requirements. The doctor wears sterile gloves to hold the handle formed by the first shell 114. The outer shape area of the handle is sterile. At the same time, the first cable 24 is drooped so as not to touch the gloves, ensuring safety during the entire operation. After use, the operator opens the second shell 115, takes out the reusable part 2 for recycling and disinfection, and discards the disposable part 1.

[0055] Example 3:

[0056] Reference Figure 7 , an endoscope in embodiment three of the present invention is given, and the specific structure and workflow of the system are described in detail below.

[0057] An endoscope includes a disposable part 1, a reuse part 2 and a display component 3, the disposable part 1 includes a handle component 11 and an insertion component 12, the handle component 11 includes a first connector 112, a accommodating cavity 113, a first shell 114, a second shell 115 and a transmission component 116, the first shell 114 forms a handle grip, an opening of the accommodating cavity 113 is provided on the side of the first shell 114, the reuse part 2 can be detachably installed in the accommodating cavity 113 or removed from the accommodating cavity 113, the second shell 115 covers the opening of the accommodating cavity 113, the reuse part 2 includes a control component 21, a drive component 22 and a second connector 23, when the reuse part 2 is installed in the accommodating cavity 113, the first connector 112 and the second connector 23 are connected.

[0058] Example 3 differs from Example 1 in that the multiplexing unit 2 and the display assembly 3 are integrally formed, and the second housing 115 covers the opening of the accommodating cavity 113, leaving a partial extension hole for the display assembly 3. The display assembly 3 includes a signal conversion unit 31, a display 32, and a mainboard 33. The multiplexing unit 2 and the display assembly 3 are directly connected by a cable, eliminating the need for a set of connectors between the multiplexing unit 2 and the display assembly 3, avoiding the risk of signal loss and increasing the stability of the transmitted image.

[0059] The insert assembly 12 is provided with a lens module and a light. These are connected to the signal conversion unit 31 via the first connector 112, the second connector 23, and cables. The lens module and light transmit signals to the signal conversion unit 31, which then processes the signals and transmits them to the mainboard 33 for display on the display 32. Because the signal conversion unit 31 is located close to the main chip of the mainboard 33, the impact of transmission distance is reduced, which helps improve image quality.

[0060] The handle assembly 11 also includes a control switch 111, which includes a motor limit switch, a motor control switch, and a photo and recording switch. The signal of the control switch 111 is input into the control assembly 21 through the first connector 112 and the second connector 23. The control assembly 21 includes a control signal board.

[0061] When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is connected to the driving assembly 22. Specifically, the driving assembly 22 includes a motor 221 and a second transmission gear 222. An encoder is provided on the motor, and the signal is input to the control signal board through a cable connection. The transmission assembly 116 is a first transmission gear, which is engaged with the insertion assembly 12. When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is engaged with the second transmission gear 222. The motor 221 can drive the insertion assembly 12 through the transmission assembly 116 and the second transmission gear 222.

[0062] The contact impedance of the first connector 112 and the second connector 23 is required to be less than 30 milliohms to ensure the continuity and uninterrupted performance of the video signal. Figure 11 As shown, the first connector 112 and the second connector 23 adopt a gold finger contact method. The maximum height of the gold finger of the PCB is only 0.02mm. When using a spring clip, the width of the gold finger needs to be widened. The spring clip must be smaller than the gold finger so that it can be fully clamped and kept inside the gold finger. The gold finger is at least 2mm wide, and the spring clip must be smaller than the gold finger to ensure that the spring clip can fully contact the gold finger without exceeding the range. The spring clip is made of brass and the gold finger is made of copper foil ounces, both of which are gold-plated with 10U, which can achieve an impedance of less than 30 milliohms. Other embodiments may also adopt a gold finger contact method.

[0063] Example 4:

[0064] Reference Figure 8 , an endoscope in embodiment 4 of the present invention is given, and the specific structure and workflow of the system are described in detail below.

[0065] An endoscope includes a disposable part 1, a reuse part 2 and a display component 3, the disposable part 1 includes a handle component 11 and an insertion component 12, the handle component 11 includes a first connector 112, a accommodating cavity 113, a first shell 114, a second shell 115 and a transmission component 116, the first shell 114 forms a handle grip, an opening of the accommodating cavity 113 is provided on the side of the first shell 114, the reuse part 2 can be detachably installed in the accommodating cavity 113 or removed from the accommodating cavity 113, the second shell 115 covers the opening of the accommodating cavity 113, the reuse part 2 includes a control component 21, a drive component 22 and a second connector 23, when the reuse part 2 is installed in the accommodating cavity 113, the first connector 112 and the second connector 23 are connected.

[0066] like Figure 13-15As shown, the fourth embodiment differs from the first embodiment in that the multiplexing unit 2 and the display assembly 3 are wirelessly connected. The multiplexing unit 2 also includes a signal conversion unit 31, a wireless transmitter chip 25, a battery 27, and a charging input module 26. The display assembly 3 includes a display 32, a mainboard 33, and a wireless receiver chip 34. The signal converted by the signal conversion unit 31, the motor control signal, and the signal from the battery 27 are wirelessly transmitted to the mainboard 33 and ultimately displayed on the display 32. The image, motor rotation status, battery power level, and other related information can be viewed on the host. The display assembly 3 is a terminal device.

[0067] Wireless transmission can be achieved in a variety of ways, such as UWB, WiFi, and other wireless technologies to achieve low-latency, high-definition image display. The multiplexing unit 2 includes a wireless transmitter chip 25, and the display component 3 includes a wireless receiver chip 34. The multiplexing unit 2 is powered by a battery 27 and a charging input module 26, and can also include a battery detection module to obtain a battery detection signal to detect the battery level.

[0068] The insertion assembly 12 is provided with a lens module and a light. The lens module and the light are connected to the signal conversion unit 31 via the first connector 112 and the second connector 23 and cables, and transmit signals to the signal conversion unit 31. The signal conversion unit 31 processes the signals and then transmits them to the mainboard 33 for display via the display 32.

[0069] The handle assembly 11 also includes a control switch 111, which includes a motor limit switch, a motor control switch, and a photo and recording switch. The signal of the control switch 111 is input into the control assembly 21 through the first connector 112 and the second connector 23. The control assembly 21 includes a control signal board.

[0070] When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is connected to the driving assembly 22. Specifically, the driving assembly 22 includes a motor 221 and a second transmission gear 222. An encoder is provided on the motor, and the signal is input to the control signal board through a cable connection. The transmission assembly 116 is a first transmission gear, which is engaged with the insertion assembly 12. When the multiplexing part 2 is installed in the accommodating cavity 113, the transmission assembly 116 is engaged with the second transmission gear 222. The motor 221 can drive the insertion assembly 12 through the transmission assembly 116 and the second transmission gear 222.

[0071] The contact impedance of the first connector 112 and the second connector 23 is required to be less than 30 milliohms to ensure the continuity and uninterrupted performance of the video signal. Figure 12 As shown, the first connector 112 and the second connector 23 utilize a spring-loaded pin structure. When the pins are pressed firmly, the solder on the PCB slightly collapses, forming a depression aligned with the pin tips, thereby creating a conductive contact area. The solder joints are made of tin, and the spring pins are made of copper with a 10µ gold plating, resulting in an impedance of less than 30 milliohms. Other embodiments may also utilize spring-loaded pin contact.

[0072] During mass production, the disposable part 1 is packaged in a sterilization box to meet the sterility requirements of the operating room. During the operation in the operating room, the doctor wears sterile gloves, and the instruments he touches must meet the sterility standards, that is, the parts touched by the gloves must be sterile areas, otherwise it may cause postoperative infection. The reusable part 2 is to be recycled and reused. Even with strict disinfection measures, it cannot achieve the same sterility level as the disposable part 1, so the sterility stability cannot be guaranteed during use. The disposable part 1 is sealed in the accommodating cavity 113 of the first shell 114 by the second shell 115 to prevent the doctor from touching the reusable part 2 during the use of the instrument to meet the sterility requirements. The doctor wears sterile gloves to hold the handle formed by the first shell 114. The outer area of the handle is sterile to ensure safety during the entire operation.

[0073] The first, second, etc. descriptions appearing in the embodiments of this application are only for illustration and distinction of the description objects. There is no order, nor does it indicate any special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application.

[0074] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
