Description

TECHNICAL FIELD

[0054] In order to make the purpose, technical scheme and advantages of the embodiment of the application more clear, the technical scheme of the embodiment of the application will be described clearly and completely below in combination with the drawings in the embodiment of the application. The described embodiments are some embodiments of the application, not all embodiments. The components of the embodiments of the application described in the drawings here can be arranged and designed in various different configurations.

[0055] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the application claimed, but merely represents selected embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0056] In the description of the application, it should be noted that:

[0057] The relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations;

[0058] “Connection” should be interpreted broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be directly connected, or indirectly connected through an intermediate medium.

[0059] The existing disposable endoscope needs to consider low cost, and there is a problem of insufficient image clarity. Some images even have defects such as noise points and horizontal lines, which seriously affect the doctor's diagnosis.

[0060] It can be solved in the following two ways:

[0061] Method one: processing the low-quality image of the endoscope into a high-quality image through a software algorithm (such as a machine learning algorithm);

[0062] Method two: using a sensor with good clarity and image acquisition function.

[0063] Although method one can optimize the image to some extent, it also has the problem of image distortion. Although method two can ensure image quality and authenticity, a sensor with higher clarity is very expensive, and the sensor will be discarded after being used once, which will greatly increase the product cost.

[0064] As Figure 1 The embodiment of the application provides a disposable endoscope module, which comprises an insertion part, an operation handle and an adapter module.

[0065] The insertion part, the operation handle and the adapter module are connected in sequence. The insertion part is used for inserting into the cavity of a living body, one end of the operation handle is connected to the base end of the insertion part, and the other end of the operation handle can be connected to the adapter module through a cable.

[0066] The part of the insertion portion to the adapter module is disposable, i.e. discarded after one use, avoiding the risk of infection and without the need for additional sterilization and maintenance procedures.

[0067] The following describes each part of the disposable endoscope module.

[0068] Figure 2 For one example shown illustratively in the present application, the tip portion 10 of the insertion portion is provided with a sensor. The operating handle 20 is provided with an angle knob, by rotating which the bending control of the insertion portion can be controlled, and can also be provided with a button.

[0069] The operating handle 20 is provided with a signal enhancement module. In some examples, as Figure 3 shown, the button can be connected to the signal enhancement module. The signal of the button can be transmitted to the sensor and the adapter module 30 through the signal enhancement module.

[0070] The sensor is used for image information acquisition and is connected to the signal enhancement module through a cable in the insertion portion.

[0071] The sensor can include a CMOS sensor or a CCD sensor. The CMOS sensor or the CCD sensor can achieve good shooting function.

[0072] As Figure 4 shown, the sensor is connected to the adapter module through the signal enhancement module. The signal enhancement module is connected to the adapter module, the signal enhancement module is used to transmit the signal to the adapter module and / or the sensor after signal enhancement, and the adapter module is used to be detachably connected to an image processing chip of an external device, so that the external device processes and / or displays the image acquired by the sensor. In some examples, as Figure 2 shown, the external device can include a relay box 40, a processing module 50, and a display module 60. The adapter module 30 is detachably connected to one end of the relay box 40, the other end of the relay box 40 is provided with a connected plug which can be connected to the processing module 50, and the relay box 40 can be provided with an image processing chip to reduce the cost of disposable disposal. The processing module 50 can be connected with an operating input part such as a keyboard and a mouse. The processing module 50 can be used to process the acquired image signal, such as blood vessel enhancement, narrowband imaging, etc., and send the processed image signal to the display module 60 for display. The processing module 50 can also power the sensor and the illumination module provided for the tip portion 10. Of course, in order to meet the portable demand, the processing module 50 and the display module 60 can be integrally provided.

[0073] The key can include a shooting key, a freeze key, and the like.

[0074] The shooting key can be a shooting image or recording image corresponding to a video, causing an image processing chip of the external device to record an image or video obtained from the sensor;

[0075] The freeze key causes the image obtained from the sensor to be displayed and frozen by a display module connected to the image processing chip, thereby being displayed as a still picture.

[0076] Of course, the key can be designed according to actual needs, and is not limited to the above functions. In the disposable endoscope module of the present application, the sensor directly collects images at the tip of the insertion part, and the signal of the sensor is enhanced by the signal enhancement module, which can meet the need for image clarity. In view of the problem of poor image display effect, the technician often ignores the influence of loss in cable transmission. Since the signal enhancement module is adopted in the present embodiment, filtering processing can be performed and the situation of large loss, voltage reduction, voltage ripple increase, noise, and more interference after transmission through a long cable can be avoided. Compared with the above-mentioned mode one and mode two, the present embodiment can achieve good display effect at a lower cost.

[0077] In addition, the image processing chip is arranged in the external device, and the disposable endoscope module is connected to the image processing chip through the adapter module, so that the image processing chip will not be discarded after being used once, thereby controlling the cost.

[0078] The adapter module can include a gold finger plug, and in some examples, the gold finger plug is connected to an adapter interface of the processing chip. In some examples, the adapter interface of the processing chip can be in the form of a relay box, and the adapter module and the gold finger plug thereof can be used as a part for one-time use, and the adapter module and the gold finger plug thereof are discarded after being used once.

[0079] In some examples, the adapter module can include a storage module; the storage module is used to store a black screen program to prevent the disposable endoscope module from being used twice. As Figure 5 The storage module can be connected to a processing module, and the processing module is connected to a display module.

[0080] The black screen program can adopt the following logic:

[0081] Step 1, in the case of detecting that the disposable endoscope module is used for the first time, obtaining the use time length of the endoscope; if it is detected that the disposable endoscope module is not used for the first time, causing the display module to be blackened;

[0082] Step 2, judging whether the use time of the endoscope exceeds a threshold value; if the use time of the endoscope exceeds the threshold value, executing Step 3; if the use time of the endoscope does not exceed the threshold value, executing Step 4;

[0083] Step 3, if the use time of the endoscope exceeds the threshold value, further judging whether the processing module is in a working state; if the processing module is in the working state, executing Step 4; if the processing module is not in the working state, executing Step 5;

[0084] Step 4, if the use time of the endoscope does not exceed the threshold value or the processing module is in the working state, continuing normal running, displaying images, and recording the use times;

[0085] Step 5, if the processing module is not in the working state, recording the use times and making the display module black screen.

[0086] The above steps can avoid the second use of the disposable endoscope module.

[0087] As Figure 6 , the signal enhancement module can include a power supply voltage stabilizing and filtering module, and the power supply end of the adapter module is connected to the power supply end of the sensor through the power supply voltage stabilizing and filtering module. Since the power supply is generally located in the processing module 50, after transmission through a relatively long cable, there will be relatively large loss, voltage reduction, voltage ripple increase, and relatively more noise and interference, etc. By adding the power supply voltage stabilizing and filtering module in the middle of the handle, the above situations can be effectively improved. Figure 2

[0088] In some examples, the signal enhancement module can further include a video signal filtering module and a clock signal filtering enhancement module; the power supply voltage stabilizing and filtering module, the video signal filtering module, and the clock signal filtering enhancement module have the following connection relationship:

[0089] The video signal end of the sensor is connected to the video signal end of the adapter module through the cable and the video signal filtering module;

[0090] The clock signal end of the adapter module is connected to the clock signal end of the sensor through the clock signal filtering enhancement module.

[0091] The video signal end, the clock signal end, and the power supply end of the adapter module can be located in the gold finger plug.

[0092] Based on the above embodiment, the embodiment of the application further provides an endoscope system, as Figure 7 , the endoscope system includes a display module, a processing module, and the above disposable endoscope module.

[0093] As​Figure 7 The display module, the processing module and the disposable endoscope module have the following connection relationship: the processing module is connected to the display module, and the disposable endoscope module is detachably connected to the processing module. The disposable endoscope module is disposable, and the display module and the processing module are reusable.

[0094] The disposable endoscope module is detachably connected to a transfer box, and then connected to the processing module through the transfer box. Figure 8 The disposable endoscope module is disposable, and the transfer box can be reusable.

[0095] An image processing chip, such as an image processing SoC chip Hi3516DV300, can be arranged in the transfer box, which can avoid discarding the image processing SoC chip after one use and the risk of infection.

[0096] As shown in Figure 9 A decoding board can be arranged in the transfer box, the image processing SoC chip can be arranged on the decoding board, and the transfer module connects the processing module through the decoding board. The decoding board can be reusable.

[0097] As shown in Figure 10 The transfer module can be provided with a storage module for storing a black screen program to prevent continued use after the second boot; the transfer box includes an image processing SoC chip, and the storage module can be connected to the image processing SoC chip through an IIC bus.

[0098] As shown in Figure 11 The transfer module can include a gold finger plug, which can be connected to the image processing SoC chip through a 20P PCI socket; the image processing SoC chip can be connected to the processing module through a 19P aviation plug.

[0099] The above described device and system embodiments are only schematic, and part or all of the modules can be selected to achieve the purpose of the embodiment scheme according to actual needs. Those skilled in the art can understand and implement without creative labor.

[0100] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements within the technical range disclosed in the present application can be easily thought of by those skilled in the art, which should be covered in the protection scope of the present application.
