Description

Technical Field

[0001] This application relates to the technical field of endoscopes, and particularly to a heat-dissipating endoscope. Background Art

[0002] An endoscope is a commonly used medical device in clinical practice. Medical staff can use endoscopic instruments to observe local lesions, obtain tissue samples, stop bleeding, excise, drain, repair, or reconstruct channels through natural body cavities or artificially created channels under direct vision or with the support of auxiliary equipment, with a wide range of application scenarios.

[0003] Endoscopes now generally use cold light sources for illumination, mainly LED light sources, xenon lamps, and halogen lamps. The cold light source is arranged outside the flexible tube of the endoscope. The cold light source is connected to the light guide fiber, and the light guide fiber is arranged in the flexible tube. One end of the light guide fiber is located in the probe at the end of the flexible tube. After inserting the probe at the end of the flexible tube into the human body, illumination can be carried out through the end of the light guide fiber.

[0004] Although the cold light source generates relatively low heat during operation, it still generates heat during operation. The light guide fiber also generates heat during operation. If the heat cannot be dissipated in time, it will affect the illumination effect of the light guide fiber and the clarity of the image. Moreover, if the temperature at the end of the light guide fiber is too high, it is easy to cause burns to human tissues. Summary of the Invention

[0005] In order to enhance the heat dissipation effect at the end of the light guide fiber, this application provides a heat-dissipating endoscope.

[0006] The heat-dissipating endoscope provided by this application adopts the following technical solutions:

[0007] A heat-dissipating endoscope, comprising:

[0008] A handle;

[0009] A flexible tube, fixedly connected to one end of the handle, wherein a light guide fiber, a water delivery pipe, and an instrument pipe are arranged in the flexible tube;

[0010] A probe, fixedly connected to the end of the flexible tube away from the handle, the probe comprising an outer tube and an imaging module. The outer tube is fixedly connected to the flexible tube, the imaging module is arranged in the outer tube, the imaging module is used for collecting images outside the probe, and the ends of the light guide fiber, the water delivery pipe, and the instrument pipe are all inserted into the outer tube;

[0011] A heat dissipation component is arranged on one side of the probe. The heat dissipation component includes a first heat conduction block, a bag body, a first fan and a second fan. The first heat conduction block and the bag body are both arranged in the outer tube. The first heat conduction block is fixedly sleeved on the outer wall of the light guide fiber. The bag body is arranged on one side of the first heat conduction block. A sealed cavity is jointly formed between the bag body and the first heat conduction block. The bag body is located between the first heat conduction block and the outer tube. The first fan and the second fan are both arranged in the handle. The air outlet side of the first fan is communicated with one side of the bag body, and the air inlet side of the second fan is communicated with the other side of the bag body, so that the air in the cavity can circulate. The tube wall of the outer tube has elasticity, so that when the air discharge volume of the first fan is greater than the air intake volume of the second fan, the bag body can bulge and the part of the outer tube in contact with the bag body is pushed outwards.

[0012] By adopting the above technical solution, the heat at the end of the light guide fiber is dissipated to the air inside the bag body through the first heat conduction block. Under the combined action of the first fan and the second fan, the air in the bag body circulates and takes away the heat in the bag body, thereby realizing the heat dissipation of the end of the light guide fiber, and thus the temperature of the end of the light guide fiber can be prevented from being too high to affect the imaging effect or cause burns to the human body; when the probe needs to be fixed in the human body, the air discharge volume of the first fan can be made greater than the air intake volume of the second fan. At this time, the air in the bag body increases, the bag body bulges, and the bulging bag body can cause the outer wall of the outer tube to expand outwards until the bag body bulges completely. At this time, the outer tube is in a supported state and the outer diameter of the outer tube increases, so that the outer tube can be stuck in the human body, thereby improving the stability of the probe, so that the doctor can observe the inside of the human body more carefully, or send a medical device into the human body through the instrument channel for corresponding operations.

[0013] Optionally, the bag body has no elasticity, so that when the air discharge volume of the first fan is the same as the air intake volume of the second fan, the bag body bulges and abuts against the inner wall of the outer tube, and the outer tube remains in its original state without deformation.

[0014] By adopting the above technical solution, when the probe needs to move smoothly in the human body, the air discharge volume of the first fan can be made the same as the air intake volume of the second fan. At this time, the bag body bulges a little, and the bulging bag body is not enough to cause the outer tube to expand outwards, so the outer tube remains its original size; the bulging bag body enables the air in the bag body to circulate smoothly and can quickly take away the heat in the bag body, which helps to ensure the heat dissipation effect; since the size of the outer tube remains unchanged, the probe can move smoothly in the human body, which helps the subsequent observation and operation processes to proceed smoothly.

[0015] Optionally, a heat-conducting ring is provided in the outer tube. The heat-conducting ring is sleeved outside the optical fiber. The heat-conducting ring is fixedly connected to the first heat-conducting block. The bag body is fixedly connected to the outside of the heat-conducting ring. The cavity is located between the bag body and the outer wall of the heat-conducting ring. The bag body is strip-shaped and arranged along the extending direction of the surface of the heat-conducting ring.

[0016] By adopting the above technical solution, the first heat-conducting block can transfer the heat at the end of the optical fiber to the heat-conducting ring. The heat-conducting ring increases the contact area with the air in the bag body, thus helping to enhance the heat dissipation effect. Since the bag body is strip-shaped and arranged along the extending direction of the surface of the heat-conducting ring, the bag body also has an annular structure. When the bag body bulges outwards and pushes the outer wall of the outer tube outwards, the outer wall of the outer tube can maintain a uniformly bulging state, thus helping to ensure the fixing effect on the probe. In addition, since the outer wall of the outer tube bulges uniformly, after the probe is fixed, the probe is in a centered state inside the human body, which helps to ensure the illumination and imaging effects.

[0017] Optionally, the imaging module includes an objective lens and an image sensor. The objective lens is fixedly connected to one end of the outer tube away from the flexible tube. The image sensor is arranged in the outer tube and fixedly connected to the objective lens. A second heat-conducting block is fixedly connected to the outside of the image sensor. The second heat-conducting block abuts against the heat-conducting ring.

[0018] By adopting the above technical solution, the heat generated when the image sensor works can be transferred to the heat-conducting ring through the second heat-conducting block. Therefore, heat dissipation of the image sensor can be achieved, which helps to ensure the normal operation of the image sensor and thus ensure the imaging quality.

[0019] Optionally, a third heat-conducting block is fixedly connected to the outside of the water supply pipe. The third heat-conducting block abuts against the heat-conducting ring.

[0020] By adopting the above technical solution, when clean water is introduced into the water supply pipe, the clean water can exchange heat with the heat-conducting ring through the third heat-conducting block. On the one hand, the temperature of the clean water is increased, making the temperature of the clean water closer to the human body temperature, thus ensuring the comfort of the human body. On the other hand, part of the heat on the heat-conducting ring can be taken away by the clean water, enhancing the heat dissipation effect of the heat-conducting ring.

[0021] Optionally, a heat-conducting wire is provided in the flexible tube. One end of the heat-conducting wire is inserted into the outer tube and fixedly connected to the heat-conducting ring. The other end of the heat-conducting wire is located in the handle.

[0022] By adopting the above technical solution, the heat-conducting wire can transfer the heat on the heat-conducting ring to the outside of the probe, thereby further enhancing heat dissipation.

[0023] Optionally, the heat-conducting wire is a copper wire.

[0024] By adopting the above technical solution, the copper wire has strong heat conductivity, which helps to ensure the heat conduction effect.

[0025] Optionally, the air outlet side of the second fan faces one end of the heat conduction wire located in the handle.

[0026] By adopting the above technical solution, the second fan can not only make the air in the bag circulate, but also the air discharged by the second fan can blow the heat conduction wire, thereby accelerating the heat dissipation at the end of the heat conduction wire and helping to enhance the heat dissipation effect.

[0027] Optionally, a heat conduction sheet is fixedly connected to one end of the heat conduction wire located in the handle.

[0028] By adopting the above technical solution, the heat dissipation area can be increased, thereby accelerating the heat dissipation of the heat conduction wire.

[0029] Optionally, an RF card is provided in the hose.

[0030] By adopting the above technical solution, only a corresponding card reader and positioning network need to be set outside. By reading the information in the RF card by the card reader and comparing it with the positioning network, the RF card can be positioned, and then the probe can be positioned, so as to clarify the position of the probe in the human body and make the probe move more accurately in the human body.

[0031] In summary, the present application includes the following beneficial technical effects:

[0032] 1. When the first fan and the second fan are working, the air in the bag can circulate. The heat at the end of the optical fiber is transferred to the heat conduction ring through the first heat conduction block. The heat conduction ring exchanges heat with the air in the bag, and the heat on the heat conduction ring is dissipated into the air in the bag. The circulating air then takes away the heat, thereby realizing the heat dissipation at the end of the optical fiber, which helps to ensure the clarity of the image and can also avoid burning the human body.

[0033] 2. When the air discharge volume of the first fan is greater than the air intake volume of the second fan, the bag can bulge. The bulging bag causes the outer tube to expand outwards. Therefore, the outer tube is propped up, increasing the outer diameter of the outer tube. The outer tube can be pressed tightly against the inside of the human body, thereby fixing the probe for better subsequent observation or inserting medical devices for corresponding operations.

[0034] 3. The heat conduction wire transfers the heat of the heat conduction ring to the outside of the probe. The second fan can dissipate the heat at the end of the heat conduction wire, which helps to enhance the heat dissipation effect of the heat conduction ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following Figures 1 - 12 is a further detailed description of the present application.

[0049] An embodiment of the present application discloses a heat dissipation endoscope. Refer to Figure 1 andFigure 2 , the heat dissipation endoscope includes a handle 1, a hose 2 and a probe 6. One end of the hose 2 is fixedly connected to the handle 1, and the other end of the hose 2 is fixedly connected to the probe 6. The probe 6 includes an outer tube 61 and an imaging module 62. One end of the outer tube 61 is closed, and the other end is open and fixedly connected to the end of the hose 2 away from the handle 1. The imaging module 62 is arranged in the outer tube 61 and is used for imaging the outside of the probe 6. Therefore, when holding the handle 1 and inserting the hose 2 into the human body, and then moving the probe 6 to the required position, the corresponding position can be illuminated and imaged, and the subsequent diagnosis and treatment can be assisted by observing the image.

[0050] Referring to Figure 3 , the imaging module 62 includes an objective lens 621 and an image sensor 622. The objective lens 621 is fixedly connected to the end of the outer tube 61 away from the hose 2. The image sensor 622 is located in the outer tube 61 and is fixedly connected to the objective lens 621. The objective lens 621 can focus the reflected light, and the image sensor 622 converts this light into an electrical signal, which is then processed and converted by an image processing system and finally displayed on a monitor, thus realizing imaging and completing the observation and diagnosis of the human body interior.

[0051] Referring to Figure 4 and Figure 5 , two bundles of angle wires 14 are arranged in the hose 2. Therefore, it is convenient to control the bending direction and angle of the hose 2 through the angle wires 14, so as to smoothly move the probe 6 to the required position.

[0052] Referring to Figures 5 - 8 , two bundles of light guide fibers 3 are arranged. One end of the light guide fiber 3 is located in the handle 1 and is fixedly connected to the light source 15 in the handle 1; the other end of the light guide fiber 3 is located in the outer tube 61. Two light guide windows 611 are opened at the end of the outer tube 61 away from the hose 2, and the two light guide windows 611 correspond to the two light guide fibers 3 respectively, and the end of the light guide fiber 3 is inserted into the light guide window 611. Therefore, the light generated by the light source 15 can be transmitted to the probe 6 through the light guide fiber 3, and then the light is emitted through the light guide window 611, thus realizing illumination. Since two light guide fibers 3 are arranged, the illumination effect on the human body interior can be enhanced.

[0053] One end of the water supply pipe 4 is located in the outer tube 61 and is communicated with the outside of the outer tube 61. The water supply pipe 4 can be connected to a water source and deliver clean water into the patient's body to ensure that during the endoscope examination and surgery, the doctor can use clean water for flushing and cleaning at any time to maintain the clarity of the field of view. One end of the instrument pipe 5 is located in the outer tube 61 and is communicated with the outside of the outer tube 61. The instrument pipe 5 enables the doctor to send other medical instruments into the human body for corresponding operations.

[0054] Referring to Figure 8 、 Figure 9 and Figure 10 In the outer tube 61, a heat conduction ring 9 is provided. The heat conduction ring 9 is a circular ring, and the heat conduction ring 9 is sleeved outside the angle steel wire 14, the optical fiber 3, the water supply pipe 4 and the instrument pipe 5. A heat dissipation component 7 is provided on one side of the outer tube 61. The heat dissipation component 7 includes a first heat conduction block 71, a bag body 72, a first blower 73 and a second blower 74. There are two first heat conduction blocks 71, which are respectively fixedly connected to the outer walls of the ends of the two optical fibers 3; the first heat conduction block 71 is fixedly connected to the inner wall of the heat conduction ring 9, so that the heat at the end of the optical fiber 3 can be transferred to the heat conduction ring 9 through the first heat conduction block 71. The bag body 72 is flexible and inelastic; the bag body 72 is arranged between the heat conduction ring 9 and the outer tube 61, and the bag body 72 is strip-shaped and arranged along the extending direction of the heat conduction ring 9. The inner side of the bag body 72 is open at one end, and the open end of the bag body 72 is fixedly connected to the outer wall of the heat conduction ring 9, so that a cavity 8 for air circulation is jointly formed between the bag body 72 and the heat conduction ring 9.

[0055] An air inlet 721 and an air outlet 722 are respectively arranged at both ends of the bag body 72. The first blower 73 and the second blower 74 are both fixedly connected to the inside of the handle 1; a connecting pipe 16 is arranged in the hose 2, and there are two connecting pipes 16 which respectively correspond to the first blower 73 and the second blower 74. One connecting pipe 16 is fixedly connected between the air outlet side of the first blower 73 and the air inlet 721 of the bag body 72, and the other connecting pipe 16 is fixedly connected between the air outlet 722 of the bag body 72 and the air inlet side of the second blower 74. Therefore, after the first blower 73 and the second blower 74 are started, the air in the bag body 72 can circulate. After the heat conduction ring 9 exchanges heat with the air in the bag body 72, the heat on the heat conduction ring 9 can be dissipated into the air in the bag body 72, and then the circulating air can take away the heat, so as to realize the heat dissipation of the heat conduction ring 9, and further realize the heat dissipation of the end of the optical fiber 3.

[0056] Wherein, the tube wall of the outer tube 61 is elastic. Under normal conditions, the outer tube 61 is in an undeformed state, and at this time, the outer diameter of the outer tube 61 is the same as the outer diameter of the hose 2. When the air discharge volume of the first blower 73 is the same as the air intake volume of the second blower 74, a part of the bag body 72 bulges. At this time, the tube wall of the outer tube 61 maintains its original state. While ensuring the smooth circulation of the air in the bag body 72, the outer tube 61 can be prevented from deforming, so that the outer tube 61 can move smoothly inside the human body.

[0057] Referring to Figure 11 and Figure 12, when the air exhaust volume of the first blower 73 is greater than the air intake volume of the second blower 74, the bag body 72 continues to bulge. The bulging bag body 72 will exert a force on the outer tube 61, causing the tube wall of the outer tube 61 to gradually bulge outwards. When the bag body 72 is fully bulged, the outer diameter of the outer tube 61 is greater than the outer diameter of the flexible tube 2. Therefore, it is convenient to clamp the outer tube 61 inside the human body at this time, so as to fix the position of the probe 6, improve the stability of the probe 6 inside the human body, and thus better observe the diseased part. Among them, the size of the bag body 72 after being fully bulged can be set as required, as long as it can fix the probe 6.

[0058] After the observation is completed and the probe 6 needs to be moved, only need to reduce the air exhaust volume of the first blower 73 and increase the air intake volume of the second blower 74, then the air in the bag body 72 can be reduced, and the elastic force of the outer tube 61 will compress the bag body 72 inwards, causing the outer tube 61 to return to its original state, thus ensuring the smooth movement of the probe 6.

[0059] Refer to Figure 10 , a second heat conducting block 10 is fixedly connected to the outer wall of the image sensor 622. The second heat conducting block 10 is fixedly connected to the inner wall of the heat conducting ring 9. Therefore, the heat of the image sensor 622 can be transferred to the heat conducting ring 9 through the second heat conducting block 10, thereby dissipating heat from the image sensor 622 to ensure the normal operation of the imaging module 62.

[0060] Furthermore, a third heat conducting block 11 is fixedly connected to the outer wall of the water supply pipe 4. The third heat conducting block 11 is fixedly connected to the inner wall of the heat conducting ring 9. Therefore, when clean water is introduced into the water supply pipe 4, the clean water can exchange heat with the heat conducting ring 9 through the third heat conducting block 11. On the one hand, it can increase the temperature of the clean water to ensure the comfort of the patient. On the other hand, it can take away part of the heat on the heat conducting ring 9, thereby enhancing the heat dissipation effect.

[0061] In addition, a heat conducting wire 12 is provided in the flexible tube 2. The heat conducting wire 12 is a copper wire. One end of the heat conducting wire 12 is located in the outer tube 61 and is fixedly connected to the inner wall of the heat conducting ring 9. The other end of the heat conducting wire 12 is located in the handle 1. Therefore, the heat conducting wire 12 can conduct the heat on the heat conducting ring 9 to the handle 1, thereby further accelerating the dissipation of the heat on the heat conducting ring 9.

[0062] Refer to Figure 8 and Figure 10 , a heat conducting sheet 13 is fixedly connected to the end of the heat conducting wire 12 located in the handle 1. The heat conducting sheet 13 is located on the air outlet side of the second blower 74. Therefore, when the endoscope is in use, the second blower 74 continuously operates to dissipate heat from the end of the light guiding fiber 3; the air discharged by the second blower 74 can blow towards the heat conducting sheet 13, so it can accelerate the heat dissipation of the heat conducting sheet 13, thereby enhancing the heat dissipation effect of the heat conducting wire 12 and the heat conducting ring 9.

[0063] A radio frequency card is also fixedly connected in the hose 2. Therefore, only a corresponding card reader and positioning network need to be set up outside. By reading the information in the radio frequency card with the card reader and comparing it with the positioning network, the radio frequency card can be positioned, and then the probe 6 can be positioned, so as to clarify the position of the probe 6 in the human body, enabling the probe 6 to move more accurately in the human body.

[0064] The implementation principle of an endoscope with heat dissipation according to an embodiment of the present application is as follows: Hold the handle 1 by hand, insert the hose 2 and the probe 6 into the human body. The light emitted by the light source 15 can be transmitted to the end of the probe 6 through the light guide fiber 3 and then emitted outward for illumination. The objective lens 621 and the image sensor 622 cooperate to transmit the internal scene back and display it on the display for the doctor to diagnose and treat. During the use of the endoscope, the first blower 73 and the second blower 74 are continuously in operation. The first blower 73 blows air into the cavity 8 inside the bag body 72, and the second blower 74 extracts the air inside the bag body 72, so that the air in the cavity 8 formed by the bag body 72 and the heat conduction ring 9 can circulate.

[0065] The heat on the light guide fiber 3 is transferred to the heat conduction ring 9 through the first heat conduction block 71, and the heat on the image sensor 622 is transferred to the heat conduction ring 9 through the second heat conduction block 10. The air circulating in the cavity 8 formed by the bag body 72 and the heat conduction ring 9 can exchange heat with the heat conduction ring 9 and then take away the heat, thereby realizing the heat dissipation of the heat conduction ring 9, and further realizing the heat dissipation of the end of the light guide fiber 3, avoiding the influence of the too high temperature of the light guide fiber 3 on the imaging effect.

[0066] During the movement of the probe 6 inside the human body, the air discharge volume of the first blower 73 is the same as the air intake volume of the second blower 74. Therefore, the bag body 72 bulges slightly, and the outer tube 61 remains in its original state, ensuring the smooth circulation of the air in the bag body 72 while enabling the probe 6 to move smoothly in the human body. When the probe 6 moves to the diseased part and needs to carefully observe and judge this part, or when it is necessary to insert a medical device for corresponding operations, the air discharge volume of the first blower 73 can be made greater than the air intake volume of the second blower 74. At this time, the air in the bag body 72 increases, and the bag body 72 continues to bulge. The bulging bag body 72 can cause the outer tube 61 to expand outward; until the bag body 72 is completely bulged, at this time the outer diameter of the outer tube 61 is greater than the outer diameter of the hose 2. Therefore, the outer wall of the outer tube 61 can fit against the inside of the patient's body to clamp the probe 6, thereby realizing the fixation of the probe 6 for subsequent observation and operations.

[0067] When it is necessary to move the probe 6, reduce the air discharge volume of the first blower 73 and increase the air intake volume of the second blower 74, and the bag body 72 can be made to contract. At this time, the outer tube 61 returns to its original state, enabling the probe 6 to continue to move smoothly.

[0068] The above are optional embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
