[0072] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0073] Endoscopes are widely used for in vivo diagnosis and treatment of living organisms. When in use, the endoscope is inserted into the organ to be examined in the living organism, so that lesions that cannot be directly observed by the naked eye can be directly observed. Therefore, a camera is usually provided on the endoscope to capture images. The images captured by the camera are transmitted to an external receiver device, and the captured images are enlarged and displayed on a display screen connected to the external receiver device.

[0074] In related technologies, a signal line is usually used to connect the core unit of an endoscope and an external receiver device to achieve signal transmission. This requires that when the endoscope is moved, the length of the signal line is limited, and the movement of the endoscope back and forth will be constrained by the signal line, which brings inconvenience to the use of the endoscope.

[0075] In view of this, the utility model provides an endoscope, which realizes wireless communication between the mirror core unit and the image processing unit by setting up built-in components, including a protective shell, a mirror core unit and a communication unit, and realizes the transmission of image data. It has higher integration and does not require an external signal line for the endoscope, thereby improving the portability of the endoscope.

[0076] The endoscope provided by the embodiment of the present utility model is described below with reference to the accompanying drawings.

[0077] refer to Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides an endoscope, comprising: a main body 10, an insertion tube assembly 20 and a built-in assembly 30, the first end of the main body 10 has a mounting cavity 123; the insertion tube assembly 20 is connected to the second end of the main body 10; the built-in assembly 30 is detachably arranged in the mounting cavity 123, the built-in assembly 30 includes a protective shell 31, a mirror core unit 32 and a communication unit 33, the protective shell 31 has a protective cavity 311, the mirror core unit 32 includes an image sensor chip 321 and a camera module 322 electrically connected to each other, the image sensor chip 321 and the communication unit 33 are both arranged in the protective cavity 311, the camera module 322 extends to the end of the insertion tube assembly 20 away from the main body 10, and the communication unit 33 is configured to provide data transmission between the mirror core unit 32 and the image processing unit.

[0078] The utility model provides an endoscope, which is equipped with a built-in component 30. The built-in component 30 includes a protective shell 31, a mirror core unit 32 and a communication unit 33, thereby realizing wireless communication between the mirror core unit 32 and the image processing unit to realize the transmission of image data, with higher integration, no need to connect an external signal line to the endoscope, and improving the portability of the endoscope.

[0079] The utility model provides an endoscope, in which the built-in component 30 is detachably arranged in the installation cavity 123, so that after each use of the endoscope, the built-in component 30 can be disassembled and reused, and only the remaining components except the built-in component 30 are discarded, which helps to save production costs.

[0080] Image sensor chips include Complementary Metal Oxide Semiconductor (CMOS) chips, and only one chip is needed to realize all basic functions of a camera.

[0081] In one possible implementation, the image processing unit includes but is not limited to a computer, etc. The image processing unit may have a display, and the image captured by the camera module 322 is displayed on the display in a timely manner to facilitate real-time observation of the lesion site.

[0082] In one possible implementation, the endoscope provided by the present invention may be a hysteroscope.

[0083] In one possible implementation, reference Figure 3 As shown, the camera module 322 can be a camera, which is used to take pictures to facilitate medical staff to observe diseased tissues.

[0084] In one possible implementation, reference Figure 3 As shown, the built-in component 30 further includes a power supply unit 35 , which is disposed in the protective cavity 311 and electrically connected to the communication unit 33 and the mirror core unit 32 .

[0085] In one possible implementation, the power supply unit 35 can be a battery, such as a lithium battery. In order to facilitate the recycling of the battery, the protective shell 31 has a charging interface to facilitate external municipal power supply to charge the battery, thereby ensuring the endurance performance of the power supply unit 35.

[0086] In one possible implementation, reference Figure 3 and Figure 4 As shown, the built-in component 30 also includes a lighting unit 34, which is arranged in the protective cavity 311, the lighting unit 34 is electrically connected to the power supply unit 35, and the lighting unit 34 is connected to a light guide, which extends to the end of the insertion tube assembly 20 away from the main body 10.

[0087] In one possible implementation, the lighting unit 34 includes but is not limited to a halogen lamp and a light-emitting diode (LED). The light-emitting diode has the advantages of small size, low power consumption, high brightness, long life, energy saving and environmental protection. The light guide can be an optical fiber, which transmits the light emitted by the lighting unit 34 to the end of the insertion tube assembly 20 away from the main body 10 to illuminate the tissue to be observed.

[0088] In other possible implementations, the lighting unit 34 may also be disposed on the inner wall of the main body 10 , or on an end of the insertion tube assembly 20 away from the main body 10 .

[0089] In a possible implementation, the built-in component 30 further includes a heat dissipation unit (not shown in the figure), which is disposed in the protective shell 31 and is configured to dissipate heat from the built-in component 30 .

[0090] In one possible implementation, the heat dissipation unit includes heat dissipation fins provided on the protective shell 31. By providing heat dissipation fins on the outer wall of the protective shell 31, the surface area of the protective shell 31 is increased, the heat dissipation effect is improved, and the use requirements of higher power supply can be met.

[0091] In another possible implementation, the heat dissipation unit includes a liquid cooling tube, which extends into the protective cavity 311. Cooling liquid, such as water, circulates in the liquid cooling tube. In this example, the liquid cooling tube may be in contact with at least one of the image sensor chip 321, the communication unit 33, the lighting unit 34, and the power supply unit 35, or in contact with the protective shell 31. For example, the liquid cooling tube may be arranged around the inner wall surface of the protective shell 31. The heat generated by the image sensor chip 321, the communication unit 33, the lighting unit 34, and the power supply unit 35 is conducted to the liquid cooling tube through the protective shell 31, and the heat is dissipated by the coolant circulating in the coolant, which helps to improve the heat dissipation efficiency, improve the timeliness of heat dissipation, and prevent the problem of accelerated aging of the image sensor chip 321, the communication unit 33, the lighting unit 34, and the power supply unit 35 due to heat accumulation. The end of the liquid cooling tube may be connected to a pump body to pump the coolant into the liquid cooling tube for circulation.

[0092] In one possible implementation, reference Figure 4 、 Figure 5 and Figure 6 As shown, the endoscope also includes an isolation tube 50, which is located inside the protective shell 31 and the insertion tube assembly 20, and an isolation channel 51 is formed inside the isolation tube 50. One end of the isolation tube 50 extending into the insertion tube assembly 20 is provided with a connecting cap 52; the image sensor chip 321 and the camera module 322 are connected by a signal line 323, and the signal line 323 and the light guide are both located in the isolation channel 51, and the camera module 322 and the light guide are both extended to the connecting cap 52.

[0093] The isolation tube 50 can be an integrally formed structure, with the isolation channel 51 being sealed around its periphery. The isolation tube 50 can protect the signal line 323 and the light guide, preventing uterine distension fluid from contaminating the signal line 323 and the light guide. This provides a more sanitary environment when the internal component 30 is disassembled for secondary use.

[0094] In one possible implementation, the isolation tube 50 is in the shape of an elongated pipe, one section of the isolation tube 50 is located in the insertion tube assembly 20, and the other section of the isolation tube 50 is located in the protective shell 31. One end of the isolation tube 50 also extends into the installation cavity 123 and is sealed with the inner wall surface of the installation cavity 123. The cross-sectional shape of the isolation tube 50 can be rectangular, circular, elliptical, etc.

[0095] In one possible implementation, the isolation tube 50 and the connecting cap 52 are sealed together. For example, sealant may be filled between the isolation tube 50 and the connecting cap 52, which not only ensures the stability of the connection, but also has a sealing and waterproof effect, preventing distending fluid from entering the isolation channel 51 from the connection position between the isolation tube 50 and the connecting cap 52, avoiding the problem of contamination of the signal line 323 and the light guide, and improving the hygiene of the secondary reuse of the built-in component 30.

[0096] In one possible implementation, reference Figure 1 、 Figure 2 and Figure 3 As shown, the main body 10 also has a first fixed pipe 124 and a second fixed pipe 125 inside. The first fixed pipe 124 is located in the installation cavity 123. The insertion tube assembly 20 also has an instrument channel 221. The second fixed pipe 125 is connected between the first fixed pipe 124 and the instrument channel 221.

[0097] During surgery, operating instruments pass through the first fixed pipe 124 , the second fixed pipe 125 and the instrument channel 221 to perform surgical operations.

[0098] In a possible implementation, a relief hole 312 is defined inside the protective shell 31 , and the first fixed pipe 124 extends into the relief hole 312 . The relief hole 312 is used to avoid the first fixed pipe 124 .

[0099] In one possible implementation, the avoidance hole 312 is located at the center of the protective shell 31 so that the protective shell 31 will not interfere with the first fixed pipe 124, which helps to increase the volume of the protective shell 31 and will not affect the operation of surgical instruments through the first fixed pipe 124.

[0100] In a possible implementation, the shape of the avoidance through hole 312 matches the shape of the first fixed pipe 124 . For example, the avoidance through hole 312 is a circular hole, and the cross-section of the first fixed pipe 124 is circular.

[0101] In one possible implementation, protective shell 31 is further provided with retaining ribs 313. These ribs surround avoidance hole 312 and block the avoidance hole 312 from protective cavity 311. These ribs separate avoidance hole 312 from protective cavity 311, enhancing protection for image sensor chip 321 and communication unit 33 and preventing damage to image sensor chip 321 and communication unit 33 during removal and installation of internal components 30.

[0102] In one possible implementation, the cross-section of the enclosure rib 313 can be a semi-circular "C" shape. Under the premise that the space is large enough, the cross-section of the protective shell 31 can be semicircular or even crescent-shaped. Such a structure does not need to avoid the first fixed pipe 124.

[0103] In one possible implementation, the communication unit 33 includes a WIFI module, a Bluetooth module, and a communication module to achieve the purpose of interconnection between the endoscope and the external image processing unit, and can remotely transmit image and video data in real time.

[0104] Wi-Fi, Bluetooth, and communication modules are currently the most common data transmission methods, offering advantages such as stable data transmission and ease of use. The Wi-Fi module transmits wireless network signals, enabling wireless data transmission between the endoscope and an external image processing unit. The communication module includes a 4G communication module, which includes a communication chip and SIM card to receive 4G network signals and facilitate 4G network communication. The communication module can also include a 5G communication module to facilitate 5G network communication.

[0105] WIFI module, Bluetooth module and communication module are available for medical staff to choose from. For example, when there is no network, use the SIM card to enable 4G or use Bluetooth at close range, and enable WIFI where there is a network to improve convenience of use.

[0106] In one possible implementation, reference Figure 5 and Figure 6 As shown, the insertion tube assembly 20 includes an outer tube 21 and an inner tube 22, the isolation tube 50 and the inner tube 22 are arranged side by side inside the outer tube 21, and a flow channel 23 for the flow of uterine fluid is formed between the inner wall of the outer tube 21, the inner tube 22 and the isolation tube 50, and the instrument channel 221 is formed inside the inner tube 22.

[0107] In one possible implementation, reference Figure 1 、 Figure 2 and Figure 5 As shown, the main body 10 includes an outer shell 11, an inner shell 12 and a first connecting pipe 16. The outer shell 11 has a first accommodating cavity 14. Figure 2 、 Figure 3 and Figure 5 As shown, the inner housing 12 includes a mounting base 121 and a second fixed pipe 125. The second fixed pipe 125 and the first connecting pipe 16 are disposed in the first accommodating chamber 14. The first connecting pipe 16 is sleeved on the outer wall of the second fixed pipe 125, and the first connecting pipe 16 and the second fixed pipe 125 bracket form a passage for the flow of uterine distension fluid.

[0108] In a possible implementation, the mounting seat 121 and the second fixed pipe 125 are connected via a transition portion 122 , and the transition portion 122 may be in a tapered tubular shape.

[0109] Reference 2 and Figure 3As shown, a cover 13 is provided on the end of the mounting base 121 facing away from the second fixed pipe 125. The cover 13 may be pivotally connected to the mounting base 121 to enable flipping of the cover 13, thereby opening or closing the mounting cavity 123. The inner wall surface of the cover 13 facing the first fixed pipe 124 has an abutment portion 131, which abuts the end of the first fixed pipe 124 to achieve a seal.

[0110] refer to Figure 1 and Figure 7 As shown, the outer shell 11 is connected to a handle 15 , and the handle 15 has an operating button 151 , which makes it convenient for medical staff to operate the endoscope by holding the handle 15 .

[0111] Before performing a hysteroscopic operation, liquid needs to be injected into the uterus to expand the uterus so that the inside of the uterine cavity can be examined and a clear image can be obtained. During the operation, the instrument performs surgery on the patient through the hysteroscope, so it is necessary to inject and discharge liquids such as distending fluid. The distending fluid is introduced into the uterine cavity before the operation and discharged after the examination.

[0112] refer to Figure 1 、 Figure 5 and Figure 7 As shown, to facilitate the injection and discharge of liquid into and from the uterus, the sidewall of the first connecting tube 16 is connected to a first interface tube 161 and a second interface tube 162. One of the first interface tube 161 and the second interface tube 162 serves as a liquid inlet tube, and the other serves as a liquid outlet tube. The first interface tube 161 and the second interface tube 162 are separated within the first connecting tube 16 so that the first interface tube 161 and the second interface tube 162 remain relatively independent. The first interface tube 161 and the second interface tube 162 are connected to the valve body 40. The liquid inlet tube is used for the injection of uterine distension fluid, and the liquid outlet tube is used for the discharge of uterine distension fluid.

[0113] Exemplary, reference Figure 1 、 Figure 5 and Figure 6 As shown, the first interface tube 161 is the liquid inlet tube, and the second interface tube 162 is the liquid outlet tube. When it is necessary to inject distending fluid into the uterus, the distending fluid enters the flow channel 23 from the first interface tube 161, and then enters the uterine cavity from the liquid inlet port opened on the connecting cap 52. When it is necessary to discharge the distending fluid from the uterus, the distending fluid enters the instrument channel 221 through the liquid discharge port opened on the connecting cap 52, and then enters the second fixed pipe 125 from the instrument channel 221, and enters the second interface tube 162 from the through hole opened on the inner wall of the second fixed pipe 125, thereby realizing the discharge of the distending fluid.

[0114] Of course, when the heat dissipation unit includes a liquid cooling tube, uterine distension fluid can also flow in the liquid cooling tube. By connecting the two ends of the liquid cooling tube to the first interface tube 161 of the endoscope and the valve body 40 respectively, the uterine distension fluid flows in the liquid cooling tube to dissipate heat for the built-in component 30 before entering the uterus. In this example, there is no need to connect additional cooling liquid to the liquid cooling tube, and the structure is simple and easy to use.

[0115] The utility model provides an endoscope with higher integration, more compact structure and fewer required connection lines.

[0116] Taking into account the high cost of the built-in component 30, by detachably setting the built-in component 30 in the mounting cavity 123 of the mounting seat 121, the built-in component 30 is effectively prevented from contacting the patient's body tissue and uterine distension fluid, ensuring that the built-in component 30 will not be contaminated, so that the built-in component 30 can be disassembled for secondary use, solving the problem of cross infection, meeting medical standards, helping to reduce production costs and ensuring safety and hygiene.

[0117] The utility model provides an endoscope. When working, the light guide guides the light emitted by the lighting unit 34 to the front end of the hysteroscope to illuminate the tissue part to be photographed, the image sensor chip 321 takes the picture, and the power supply unit 35 provides power output, so that the use of the endoscope is free from the constraints of wires, and the portability is better and easier to move. The communication unit 33 transmits the captured video image data to the receiving module of the external image processing unit in real time, which is more convenient to use.
