Description

Technical Field

[0001] The present application relates to the technical field of endoscopes, and in particular to a heat dissipation endoscope. Background Art

[0002] Endoscopes are commonly used medical devices in clinical practice. Medical personnel can use endoscopes to observe local lesions, obtain tissue samples, stop bleeding, resect, drain, repair or reconstruct channels through natural cavities of the human body or artificially created channels under direct vision or with the support of auxiliary equipment. It has a wide range of application scenarios.

[0003] Endoscopes now generally use cold light sources for lighting, mainly LED light sources, xenon lamps, and halogen lamps. The cold light source is set outside the hose of the endoscope, and the cold light source is connected to the optical fiber. The optical fiber is set in the hose, and one end of the optical fiber is located in the probe at the end of the hose. After the probe at the end of the hose is inserted into the human body, lighting can be performed through the end of the optical fiber.

[0004] Although the heat generated by the cold light source is relatively low when working, it still generates heat when working. The optical fiber also generates heat when working. If the heat cannot be dissipated in time, it will affect the lighting effect of the optical fiber and the clarity of the image. Moreover, the temperature at the end of the optical fiber is too high, which can easily cause burns to human tissue. Summary of the invention

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

[0006] The heat dissipation endoscope provided in this application adopts the following technical solution: A heat dissipation endoscope, comprising: handle; A hose, fixedly connected to one end of the handle, wherein a light guide fiber, a water delivery pipeline and an instrument pipeline are arranged in the hose; A probe, fixedly connected to an end of the hose away from the handle, the probe comprising an outer tube and an imaging module, the outer tube being fixedly connected to the hose, the imaging module being arranged in the outer tube, the imaging module being used to collect images outside the probe, the ends of the optical fiber, the water delivery pipe and the instrument pipe being inserted in the outer tube; A heat dissipation component is arranged on one side of the probe, and the heat dissipation component includes a first heat-conducting block, a bag body, a first fan and a second fan. The first heat-conducting block and the bag body are both arranged in an outer tube, and the first heat-conducting block is fixedly sleeved on the outer wall of the optical fiber. The bag body is arranged on one side of the first heat-conducting block, and a closed cavity is formed between the bag body and the first heat-conducting block. The bag body is located between the first heat-conducting block and the outer tube. The first fan and the second fan are both arranged in a handle. The air outlet side of the first fan is connected to one side of the bag body, and the air inlet side of the second fan is connected to the other side of the bag body, so that the air in the cavity can circulate. The tube wall of the outer tube is elastic, so that when the exhaust volume of the first fan is greater than the 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 propped outward.

[0007] By adopting the above technical solution, the heat at the end of the optical fiber is dissipated to the air inside the bag body through the first heat conductive block. With the cooperation 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 achieving heat dissipation of the end of the optical fiber, thereby preventing the temperature of the end of the optical fiber from being too high and affecting the imaging effect or causing burns to the human body; when the probe needs to be fixed in the human body, the exhaust volume of the first fan can be made greater than the intake volume of the second fan. At this time, the air in the bag body increases, the bag body will bulge, and the bulging bag body can make the outer wall of the outer tube expand outward until the bag body is completely bulged. At this time, the outer tube is in a propped-up state, and the outer diameter of the outer tube is increased, so that the outer tube can be stuck in the human body, thereby improving the stability of the probe, so that the doctor can make a more detailed observation of the inside of the human body, or send the medical device into the human body through the instrument channel for corresponding operation.

[0008] Optionally, the bag body is not elastic, so that when the exhaust volume of the first fan and the intake volume of the second fan are the same, the bag body bulges and presses against the inner wall of the outer tube, and the outer tube maintains its original shape and does not deform.

[0009] By adopting the above technical solution, when the probe needs to move smoothly in the human body, the exhaust volume of the first fan and the intake volume of the second fan can be made the same. At this time, the bag body bulges a small part, and the bulged bag body is not enough to make the outer tube expand outward, so the outer tube maintains its original size; the bulged bag body allows the air in the bag body to flow smoothly, and can quickly take away the heat in the bag body, which helps to ensure the heat dissipation effect; because the size of the outer tube remains the same, the probe can move smoothly in the human body, which is conducive to the smooth progress of subsequent observation and operation processes.

[0010] Optionally, a heat-conducting ring is provided in the outer tube, the heat-conducting ring is sleeved on the outside of 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, and the bag body is in the shape of an elongated strip and is arranged along the extension direction of the surface of the heat-conducting ring.

[0011] 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, and the heat-conducting ring increases the contact area with the air in the bag body, thereby helping to enhance the heat dissipation effect; because the bag body is in the shape of an elongated strip and is arranged along the extension direction of the surface of the heat-conducting ring, the bag body also has a ring structure. When the bag body bulges outward and props up the outer wall of the outer tube outward, the outer wall of the outer tube can maintain a uniform bulging state, thereby helping to ensure the fixation effect of the probe; in addition, because 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 lighting and imaging effects.

[0012] 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 hose, the image sensor is arranged in the outer tube and fixedly connected to the objective lens, and a second heat conductive block is fixedly connected to the outer side of the image sensor, and the second heat conductive block is against the heat conductive ring.

[0013] By adopting the above technical solution, the heat generated by the image sensor during operation can be transferred to the heat-conducting ring through the second heat-conducting block, thereby achieving heat dissipation for the image sensor, helping to ensure the normal operation of the image sensor, thereby ensuring imaging quality.

[0014] Optionally, a third heat-conducting block is fixedly connected to the outer side of the water supply pipe, and the third heat-conducting block abuts against the heat-conducting ring.

[0015] By adopting the above technical solution, when clean water is passed 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, thereby ensuring the comfort of the human body; on the other hand, the clean water can take away part of the heat on the heat-conducting ring, thereby enhancing the heat dissipation effect of the heat-conducting ring.

[0016] Optionally, a heat-conducting wire is provided in the hose, one end of the heat-conducting wire is inserted into the outer tube and fixedly connected to the heat-conducting ring, and the other end of the heat-conducting wire is located in the handle.

[0017] 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 the heat dissipation.

[0018] Optionally, the heat conductive wire is a copper wire.

[0019] By adopting the above technical solution, the copper wire has strong thermal conductivity, which helps to ensure the thermal conductivity effect.

[0020] Optionally, the air outlet side of the second fan faces toward an end of the heat guide wire located in the handle.

[0021] By adopting the above technical solution, the second fan can not only circulate the air in the bag body, but the air exhausted by the second fan can also blow on the heat conducting wire, thereby accelerating the heat dissipation of the end of the heat conducting wire, which helps to enhance the heat dissipation effect.

[0022] Optionally, one end of the heat-conducting wire located in the handle is fixedly connected to a heat-conducting sheet.

[0023] By adopting the above technical solution, the heat dissipation area can be increased, thereby accelerating the heat dissipation of the heat conductive wire.

[0024] Optionally, a radio frequency card is provided in the hose.

[0025] By adopting the above technical solution, it is only necessary to set up a corresponding card reader and a positioning network in the outside world. By reading the information in the radio frequency card through the card reader and comparing it with the positioning network, the radio frequency card can be positioned, and then the probe can be positioned, so as to clearly determine the position of the probe in the human body, so that the probe can move more accurately in the human body.

[0026] In summary, this application includes the following beneficial technical effects: 1. When the first fan and the second fan are working, the air in the bag can be circulated, and the heat at the end of the optical fiber is transferred to the heat-conducting ring through the first heat-conducting block. The heat-conducting ring exchanges heat with the air in the bag, and the heat on the heat-conducting ring is dissipated into the air in the bag. The circulating air takes the heat away, thereby achieving heat dissipation of the end of the optical fiber, which helps to ensure the clarity of the image and avoid burns to the human body.

[0027] 2. When the exhaust volume of the first fan is greater than the intake volume of the second fan, the bag body may swell, and the swollen bag body causes the outer tube to expand outward, so that the outer tube is propped up, and the outer diameter of the outer tube increases, and the outer tube can be pressed against the inside of the human body, thereby fixing the probe, so as to facilitate better subsequent observation or insertion of medical equipment for corresponding operations.

[0028] 3. The heat conducting wire transfers the heat of the heat conducting ring to the outside of the probe, and the second fan can dissipate heat at the end of the heat conducting wire, thereby helping to enhance the heat dissipation effect of the heat conducting ring.

DETAILED DESCRIPTION

[0031] The following combination Figure 1-Figure 12 This application is described in further detail.

[0032] The present application embodiment discloses a heat dissipation endoscope. Figure 1 and Figure 2The 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 to image the outside of the probe 6. Therefore, after holding the handle 1 and inserting the hose 2 into the human body, the probe 6 is moved to the desired part, and the corresponding position can be illuminated and imaged, and the subsequent diagnosis and treatment can be coordinated by observing the imaging.

[0033] Reference 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 the image sensor 622 is fixedly connected to the objective lens 621. The objective lens 621 can focus the reflected light, and the image sensor 622 converts the light into electrical signals, which are then processed and converted by the image processing system and finally displayed on the display, thereby realizing imaging and completing the observation and diagnosis of the inside of the human body.

[0034] Reference Figure 4 and Figure 5 The hose 2 is provided with an angle steel wire 14, an optical fiber 3, a water delivery pipe 4 and an instrument pipe 5. The angle steel wire 14 is provided with two bundles, so that the bending direction and angle of the hose 2 can be controlled by the angle steel wire 14, so as to smoothly move the probe 6 to the desired position.

[0035] Reference Figure 5-Figure 8 , two bundles of light guide fibers 3 are provided, one end of the light guide fibers 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 fibers 3 is located in the outer tube 61, and a light guide window 611 is provided at one end of the outer tube 61 away from the hose 2, two light guide windows 611 are provided and correspond to the two light guide fibers 3 respectively, and the ends of the light guide fibers 3 are inserted into the light guide windows 611. Therefore, the light generated by the light source 15 can be transmitted to the probe 6 through the light guide fibers 3, and then the light is emitted through the light guide windows 611, thereby realizing illumination. Since two light guide fibers 3 are provided, the illumination effect on the inside of the human body can be enhanced.

[0036] One end of the water delivery pipe 4 is located in the outer tube 61 and is connected to the outside of the outer tube 61. The water delivery pipe 4 can be connected to a water source and deliver clean water to the patient's body to ensure that during endoscopic examination and surgery, the doctor can use clean water for flushing and cleaning at any time to maintain the clarity of the field of vision. One end of the instrument pipe 5 is located in the outer tube 61 and is connected to the outside of the outer tube 61. The instrument pipe 5 allows the doctor to deliver other medical instruments into the human body for corresponding operations.

[0037] Reference Figure 8 , Fig. 9 and Fig.10 , a heat-conducting ring 9 is arranged in the outer tube 61, and the heat-conducting ring 9 is a circular ring. The heat-conducting ring 9 is sleeved on the outside of 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 arranged on one side of the outer tube 61, and the heat dissipation component 7 includes a first heat-conducting block 71, a bag body 72, a first fan 73 and a second fan 74. Two first heat-conducting blocks 71 are arranged, which are respectively fixedly connected to the outer walls of the ends of the two optical fibers 3; the first heat-conducting block 71 is fixedly connected to the inner wall of the heat-conducting ring 9, so that the heat at the ends of the optical fibers 3 can be transferred to the heat-conducting ring 9 through the first heat-conducting block 71. The bag body 72 is flexible and not elastic; the bag body 72 is arranged between the heat-conducting ring 9 and the outer tube 61, and the bag body 72 is in a long strip shape and is arranged along the extension direction of the heat-conducting ring 9. The inner side of the bag body 72 is opened, and one end of the bag body 72 is fixedly connected to the outer wall of the heat-conducting ring 9, so that a cavity 8 for air circulation is formed between the bag body 72 and the heat-conducting ring 9.

[0038] The two ends of the bag body 72 are respectively provided with an air inlet 721 and an air outlet 722. The first fan 73 and the second fan 74 are both fixedly connected to the inside of the handle 1; the hose 2 is provided with a connecting pipe 16, and two connecting pipes 16 are provided and correspond to the first fan 73 and the second fan 74 respectively. One of the connecting pipes 16 is fixedly connected between the air outlet side of the first fan 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 fan 74. Therefore, after the first fan 73 and the second fan 74 are started, the air in the bag body 72 can be circulated, so that after the heat-conducting ring 9 exchanges heat with the air in the bag body 72, the heat on the heat-conducting ring 9 can be dissipated into the air in the bag body 72, and then the circulating air can take away the heat, thereby realizing the heat dissipation of the heat-conducting ring 9, and then realizing the heat dissipation of the end of the optical fiber 3.

[0039] The wall of the outer tube 61 is elastic. Under normal conditions, the outer tube 61 is in an undeformed state, and the outer diameter of the outer tube 61 is the same as the outer diameter of the hose 2. When the exhaust volume of the first fan 73 and the intake volume of the second fan 74 are the same, the bag body 72 bulges a part, and the wall of the outer tube 61 maintains its original shape, which ensures that the air in the bag body 72 flows smoothly while preventing the outer tube 61 from deforming, so that the outer tube 61 can move smoothly inside the human body.

[0040] Reference Fig.11 and Fig.12When the exhaust volume of the first fan 73 is greater than the intake volume of the second fan 74, the bag body 72 continues to swell, and the swollen bag body 72 will exert a force on the outer tube 61, causing the tube wall of the outer tube 61 to gradually swell outward. When the bag body 72 is fully swollen, the outer diameter of the outer tube 61 is greater than the outer diameter of the hose 2, so it is convenient to clamp the outer tube 61 inside the human body, thereby fixing the position of the probe 6, so as to improve the stability of the probe 6 inside the human body, so as to better observe the patient's part. Among them, the size of the bag body 72 after it is fully swollen can be set according to needs, as long as it can achieve the fixation of the probe 6.

[0041] After the observation is completed, when the probe 6 needs to be moved, it is only necessary to reduce the exhaust volume of the first fan 73 and increase the air intake volume of the second fan 74 to reduce the air in the bag body 72. The elastic force of the outer tube 61 compresses the bag body 72 inward, so that the outer tube 61 returns to its original state, thereby ensuring the smooth movement of the probe 6.

[0042] Reference Fig.10 A second heat-conducting block 10 is fixedly connected to the outer wall of the image sensor 622, and 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 the heat of the image sensor 622 to ensure the normal operation of the imaging module 62.

[0043] Furthermore, a third heat-conducting block 11 is fixedly connected to the outer wall of the water supply pipe 4, and the third heat-conducting block 11 is fixedly connected to the inner wall of the heat-conducting ring 9. Therefore, when clean water is passed 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, the temperature of the clean water can be increased 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.

[0044] In addition, a heat conducting wire 12 is provided in the hose 2, and 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 fixedly connected to the inner wall of the heat conducting ring 9, and the other end of the heat conducting wire 12 is located in the handle 1, so that the heat conducting wire 12 can conduct the heat on the heat conducting ring 9 to the handle 1, thereby further accelerating the heat loss on the heat conducting ring 9.

[0045] Reference Figure 8 and Fig.10 One end of the heat-conducting wire 12 located in the handle 1 is fixedly connected with a heat-conducting sheet 13, and the heat-conducting sheet 13 is located on the air outlet side of the second fan 74. Therefore, when the endoscope is in use, the second fan 74 continues to operate to achieve heat dissipation of the end of the optical fiber 3; the wind discharged by the second fan 74 can blow toward the heat-conducting sheet 13, thereby accelerating 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.

[0046] A radio frequency card is also fixedly connected to the hose 2, so it is only necessary to set up a corresponding card reader and a positioning network outside. The radio frequency card can be positioned by reading the information in the radio frequency card through the card reader and comparing it with the positioning network, and then the probe 6 can be positioned, so as to clearly determine the position of the probe 6 in the human body, so that the probe 6 can be moved more accurately in the human body.

[0047] The implementation principle of a heat dissipation endoscope in an embodiment of the present application is as follows: holding the handle 1, inserting 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 optical fiber 3, and then emitted outward, thereby illuminating. The objective lens 621 and the image sensor 622 cooperate to transmit the internal scene back and display it on the display so that the doctor can diagnose and treat. During the use of the endoscope, the first fan 73 and the second fan 74 are continuously in operation, the first fan 73 blows air into the cavity 8 inside the bag body 72, and the second fan 74 draws out the air inside the bag body 72, so that the air in the cavity 8 composed of the bag body 72 and the heat conductive ring 9 can circulate.

[0048] The heat on the optical fiber 3 is transferred to the thermal ring 9 through the first thermal block 71, and the heat on the image sensor 622 is transferred to the thermal ring 9 through the second thermal block 10. The air circulating in the cavity 8 composed of the bag body 72 and the thermal ring 9 can exchange heat with the thermal ring 9 and then take the heat away, thereby achieving heat dissipation of the thermal ring 9, and then achieving heat dissipation of the end of the optical fiber 3, thereby preventing the optical fiber 3 from having an excessively high temperature and affecting the imaging effect.

[0049] During the movement of the probe 6 inside the human body, the exhaust volume of the first fan 73 and the intake volume of the second fan 74 are the same, so the bag body 72 is slightly bulged, and the outer tube 61 remains in its original state, ensuring the smooth flow of air in the bag body 72 while allowing the probe 6 to move smoothly inside the human body. When the probe 6 moves to the lesion site and needs to be carefully observed and judged, or needs to be inserted into a medical device for corresponding operation, the exhaust volume of the first fan 73 can be made greater than the intake volume of the second fan 74, at which time the air in the bag body 72 increases, the bag body 72 continues to bulge, and the bulging bag body 72 can cause the outer tube 61 to expand outward; until the bag body 72 is completely bulged, at which time the outer diameter of the outer tube 61 is greater than the outer diameter of the hose 2, so that the outer wall of the outer tube 61 can fit inside the patient's body, clamping the probe 6, thereby achieving the fixation of the probe 6 for subsequent observation and operation.

[0050] When the probe 6 needs to be moved, the exhaust volume of the first fan 73 is reduced and the intake volume of the second fan 74 is increased, so that the bag body 72 can be contracted. At this time, the outer tube 61 returns to its original state, so that the probe 6 can continue to move smoothly.

[0051] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
