The endoscope commonly seen in clinic is classified according to hard mirror and soft mirror, compared with hard mirror, the feature of soft mirror is that mirror body can be bent, so that the lens part can be controlled to change direction, inserted into some observation positions that hard mirror cannot reach.

[0003] Whether it is hard mirror or soft mirror, endoscope mirror body subassembly usually includes insertion tube, operating handle and wire harness tube, the operating handle is connected at the rear end of insertion tube, the wire harness tube is connected at the rear end of operating handle, and the plug-in connector is arranged at the rear end of wire harness tube, the plug-in connector is used to realize the connection of mirror body subassembly and each module on endoscope host computer, the module includes one or several of camera module, light source module, negative pressure suction module, water device module and the like.

In view of this problem, in the prior art, the patent file with the patent application number CN201910815141.1 provides an endoscope camera and an endoscope camera system, the technical scheme provided by the patent file maintains the temperature of the shell in a suitable temperature range through the setting of the cooling assembly, so that the user can hold the operating handle for a long time to complete the relevant operation and improve the use experience. At the same time, a cooling assembly including an air inlet and an air outlet is disclosed to cool in a wind cooling manner.

[0005] Endoscope is a medical instrument widely used in medical field, and further optimization of endoscope will undoubtedly promote the development of medical industry. UTILITY MODEL CONTENT

[0006] In view of the problem of further optimizing the above-mentioned endoscope, the utility model provides an endoscope mirror body subassembly and endoscope. The scheme can effectively solve the problem of local high temperature of the mirror body subassembly, and the related improvement does not affect the cleaning and disinfection performance of the endoscope.

[0007] To solve the above problems, the utility model provides a kind of endoscope mirror body assembly and endoscope are solved by the following technical points: a kind of endoscope mirror body assembly, including operating handle, the operating handle is connected with wire harness pipe and insertion tube, further include the cooling device for the heat generating component in operating handle cooling, the cooling device includes the circulation pipeline for providing heat carrier medium flow channel, circulation pipeline part is located in first space, other parts of circulation pipeline are located in second space, the first space is the space in operating handle, the second space is the space in wire harness pipe or the space in insertion tube;

[0008] The cooling device further includes a pump, the pump is connected in series on the circulation pipeline and serves as a power element for circulating the heat carrier medium in the circulation pipeline, and the pump is arranged in the first space or the second space.

[0009] In the present scheme, the insertion tube is a rod-shaped structure at the front end of the operating handle, and the front end of the insertion tube serves as an insertion end of the endoscope inserted into the human body during use of the endoscope.The wire harness pipe is a tubular structure at the rear end of the operating handle, and the rear end of the wire harness pipe is connected to the main machine of the endoscope during use of the endoscope, and the specific connection objects include a camera module, a light source module, a water and gas module, and a negative pressure suction module.The operating handle is a structure for a medical staff to hold the endoscope mirror body during use of the endoscope mirror body.In the prior art, the AFE module of the electronic ultrasonic gastroscope is preposed to the operating handle, the imaging module is usually arranged in the operating handle of the white light camera and the fluorescence camera handle, and the operating handle of the light source preposed electronic gastroscope and electronic enteroscope has a light source module as a light source in addition to the action driving module.The above endoscope mirror body assembly generates a lot of heat when in use, and the surface temperature of the operating handle can reach 40 DEG C or even above when the operating handle is held for a long time by a medical staff because the outer wall of the operating handle is covered, which not only causes the medical staff to have an uncomfortable feeling, but also affects the service life of the endoscope.In the technical solution provided in patent application No.CN201910815141.1, a cold fluid treatment is adopted, and the specific structure includes a fluid inlet and a fluid outlet, and a air cooling treatment is also provided, and the specific structure includes an air inlet and an air outlet.

[0010] The present scheme is aimed at the electronic gastroscope, electronic enteroscope and electronic ultrasonic gastroscope widely used in endoscopes, which have washing and disinfecting performance requirements, and provides a technical solution that can better meet the sealing performance requirements of the endoscope mirror body assembly while solving the heat concentration problem on the operating handle, to ensure the cleaning and disinfecting performance of the endoscope.

[0011] In the above scheme, specifically, the internal space of the circulation pipeline is the heat carrier flow channel, and the pump is connected in series on the circulation pipeline. In this way, when the pump is working, the pump drives the heat carrier to circulate in the circulation pipeline. When the heat carrier flows through the first space, the heat in the first space can be transferred to the heat carrier through the circulation pipeline or through the heat absorption assembly arranged separately on the circulation pipeline. When the heat-absorbed heat carrier flows through the second space, the heat of the heat carrier can be transferred to the second space through the circulation pipeline or through the heat release assembly arranged separately on the circulation pipeline. In this way, according to the characteristics of the electronic wire harness, the fluid medium guide pipe and the light guide medium inserted into the pipe and the wire harness pipe, the heat in the first space can be transferred to the wire harness pipe and the insertion pipe through the cooling device. Therefore, even if the surface of the operating handle is poorly cooled because the operating handle is held for a long time, the heat generated by the heat-generating component in the first space can be forcibly transferred to the wire harness pipe and the insertion pipe through the cooling device, so as to control the temperature rise of the surface of the operating handle and the first space.

[0012] Meanwhile, in the present scheme, the heat is removed from the surface of the operating handle and the first space by the cooling device, and the heat is only transferred to the second space which does not affect the operation of the endoscope by the medical staff and reduces the temperature of the heat-generating component. Therefore, the principle of temperature control of the operating handle in the present scheme is to transfer heat to expand the heat storage area and increase the heat dissipation area, and it is not necessary to set medium inlet and outlet for the cooling device on the surface of the endoscope body. Therefore, from the perspective of the sealing property of the endoscope, the present scheme is beneficial to the sterilization and cleaning performance of the endoscope, and can achieve the purpose of controlling the temperature of the surface of the operating handle and the inside of the endoscope while ensuring the reliability of the endoscope.

[0013] Meanwhile, in the present scheme, the volume of the heat storage structure and the heat exchange area are increased by the cooling device. In this way, the heat distribution on the endoscope body assembly is uniformed, the temperature at the position of the operating handle is reduced, and the heat can be transferred to the outside through other parts of the present assembly. Therefore, the present scheme will not cause obvious temperature change in other parts.

[0014] As a person skilled in the art, the circulation pipeline itself has heat transfer performance. Therefore, in the present scheme, the heat absorption and release of the heat carrier can be realized based on the circulation pipeline as a heat conduction pipe. Such implementation requires that the circulation pipeline itself has good heat transfer capacity, and the implementation of these means including material selection, wall thickness selection and the like does not require creative labor.

[0015] To meet the embedded installation of the cooling device on the endoscope lens assembly, the pump available in the prior art is a micro pump. Since the pump itself becomes a heat source when working, preferably, the cooling device further comprises a temperature sensor arranged in the first space. When the temperature sensor detects that the temperature in the first space is higher than a set threshold, the pump is manually controlled or automatically triggered to work to reduce the total heat generated during use of the endoscope lens assembly. Further, to ensure the operation accuracy of the endoscope during use, the cooling device further comprises a prompt module outputting light or sound to remind the user to pay attention before the pump is automatically triggered to work, so as to avoid the vibration caused by the start of the pump from interfering with the operation accuracy of the endoscope.

[0016] Regarding the wire harness tube, in the prior art, the wire harness tube is a structure connecting the lens assembly and the endoscope main machine, and the end of the wire harness tube is provided with a plug connector which is generally integrally formed on the wire harness tube. Regarding the wire harness tube, the wire harness tube comprises a wire harness tube body and a plug connector, and regarding the space in the wire harness tube, it should be understood as including the space in the wire harness tube body and the space in the plug connector. For example, when the pump needs to be arranged in the space in the plug connector, the circulation pipeline extends from the first space to the space in the plug connector through the space in the wire harness tube body to the space in the plug connector. Therefore, under this concept, the possible embodiments include that part of the circulation pipeline is located in the first space, and the other part of the circulation pipeline is located in the space in the wire harness tube body and the space in the plug connector.

[0017] As a further technical solution of the endoscope lens assembly:

[0018] To facilitate the arrangement of the cooling device in the limited first space and second space, preferably, the circulation pipeline is a flexible tube, and the pump is arranged in the first space. In this scheme, the flexible tube is used to adapt to the arrangement of the circulation pipeline in the first space and the second space, and the first space is used to have more idle space than the second space to facilitate the arrangement of the pump.

[0019] As described above, the circulation pipeline itself can be used as a heat transfer pipe to introduce the heat in the first space into the second space in a partitioned heat exchange manner. However, this puts higher requirements on the selection of the circulation pipeline. To solve this problem, preferably, the circulation pipeline is provided with a heat absorption assembly located in the first space and a heat release assembly located in the second space.

[0020] Compared with the circulating pipeline, the heat absorption assembly is used to enhance the heat conduction capacity of the heat carrier and the peripheral environment of the heat absorption assembly, and the heat release assembly is used to enhance the heat conduction capacity of the heat carrier and the peripheral environment of the heat release assembly. In this scheme, it is easy to understand that the above heat absorption assembly and heat release assembly can be the same structure or different structure. When they are the same structure, the reason for using different names is that when the structure is in different temperature environments, it will cause the heat absorption or heat release of the heat carrier, so the relevant naming can be considered as only distinguishing the structure from the function. At the same time, as a person skilled in the art, the heat absorption assembly and the heat release assembly can be a pipe connected to the circulating pipeline, or a pipe segment different from other positions on the circulating pipeline.

[0021] As a specific implementation of the heat absorption assembly, the heat absorption assembly is one or more of the following structures: a coil pipe connected in series with the circulating pipeline, a heat conduction plate mounted on the circulating pipeline, a branch pipe connected in series with the circulating pipeline, and a metal pipe segment connected in series with the circulating pipeline. The branch pipe is multiple, and the branch pipes are in parallel relationship with each other. When it is a coil pipe, in order to make the heat carrier have good heat absorption capacity, the coil pipe is wrapped around the heating component. When it is a heat conduction plate, the heat conduction plate can be mounted on the outer wall of the circulating pipeline, or the heat conduction plate can provide a heat carrier flow channel connected in series with the circulating pipeline. When it is a branch pipe, the branch pipe is a branch pipe on the circulating pipeline to increase the heat absorption area of the circulating pipeline in the first space. From the point of view of heat carrier flow capacity and pressure bearing capacity, the branch pipe can be thinner and thinner. It not only can be set to have better heat transfer adhesion quality with the heating component, but also can easily pass through the gap on the heating component and the gap between the heating components, thereby expanding the direct heat absorption area of the circulating pipeline in the first space. When it is a metal pipe segment, the metal pipe segment generally has a large heat transfer coefficient to ensure the heat absorption effect of the heat carrier in the first space.

[0022] As the same as the above heat absorption assembly, the heat release assembly is one or more of the following structures: a coil pipe connected in series with the circulating pipeline, a heat conduction plate mounted on the circulating pipeline, a branch pipe connected in series with the circulating pipeline, and a metal pipe segment connected in series with the circulating pipeline. The branch pipe is multiple, and the branch pipes are in parallel relationship with each other. As a person skilled in the art, this scheme provides a specific implementation of the heat release assembly from the heat dissipation of the heat carrier. The principle of heat dissipation of the heat carrier through the heat release assembly is the same as the principle of heat absorption of the heat carrier through the heat absorption assembly.

[0023] As a small volume heat conduction plate scheme that provides a heat carrier flow channel itself to ensure the heat transfer effect, the heat conduction plate is a micro-channel heat conduction plate.

[0024] For the specific use of the specific heating component, the heating component in the first space is set as the heating component of the image sensor, and the heat absorption assembly is a coil pipe or a branch pipe. When the heat absorption assembly is a heat conduction plate or a metal pipe segment, the heat absorption assembly is wrapped around the image sensor.

[0025] For the specific use of the specific heating component, the heating component in the first space is set as the heating component of the image sensor, and the heat absorption assembly is a coil pipe or a branch pipe. When the heat absorption assembly is a heat conduction plate or a metal pipe segment, the heat absorption assembly is wrapped around the image sensor.

[0026] In order to reduce the influence of the heating of the handle part on the temperature rise of the insertion tube, avoid the stimulation of the patient caused by the use of the endoscope, and further expand the heat storage volume and heat dissipation area of the heat generating component by using the conductive structure on the wire harness tube, the second space is the space in the wire harness tube, one end of the wire harness tube is connected with the handle, and the other end of the wire harness tube is provided with a plug connector for connecting the main machine of the endoscope, and the plug connector is provided with a metal structure.

[0027] The circulating pipeline extends to one end of the plug connector on the wire harness tube through the second space, and the heat dissipation assembly in the second space is arranged on the circulating pipeline. The heat dissipation assembly is a heat conduction plate mounted on the circulating pipeline or a metal pipe segment connected with the circulating pipeline. The heat dissipation assembly is in surface contact with the metal structure or is an integral structure. In this scheme, the good heat conduction ability of the conductive metal structure is used to expand the heat storage volume and heat dissipation area. The heat dissipation assembly in this scheme is used to strengthen the heat conduction ability of the heat carrying medium and the conductive metal structure. The integral structure is that the heat dissipation assembly and the conductive metal structure are arranged as an integral structure. As a person skilled in the art, the metal structure is a component of the plug connector. The metal structure on the plug connector includes a metal structure for conducting electricity and a metal structure for connection.

[0028] In order to adapt to the requirements of the space in the endoscope lens assembly for the size of the circulating pipeline, the circulating pipeline is a capillary hose or a plastic hose. In specific implementation, in order to adapt to the size design of the assembly and facilitate the layout of the circulating pipeline, the circulating pipeline is preferably designed to have an inner diameter of less than 3 mm. The wall thickness of the circulating pipeline is designed by comprehensively considering the material performance under the selection of heat conduction ability. The capillary hose is a rubber hose, and the plastic hose is a plastic hose.

[0029] The present scheme also relates to an endoscope comprising the endoscope lens assembly according to any one of the above. The endoscope is an endoscope comprising the endoscope lens assembly, and is a specific use of the endoscope lens assembly.

[0030] The utility model has the following beneficial effects:

[0031] This solution adopts a mode in which a heat-carrying medium circulates through a cooling device in the scope assembly, and adopts the setting characteristics of a circulation pipeline passing through the first space and the second space, thereby providing a technical solution that can solve the problem of heat concentration on the operating handle while better meeting the sealing performance requirements of the endoscope scope assembly to ensure the cleaning and disinfection performance of the endoscope.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the following embodiments, but the present invention is not limited to the following embodiments:

[0037] Example 1:

[0038] like Figs. 1 to 3 As shown, an endoscope body assembly includes an operating handle 2, to which a wiring harness tube 6 and an insertion tube 1 are connected, and further includes a cooling device for cooling a heat-generating component 3 in the operating handle 2, the cooling device including a circulation pipeline 8 for providing a flow path for a heat-carrying medium, wherein a portion of the circulation pipeline 8 is located in a first space 5, and the remaining portion of the circulation pipeline 8 is located in a second space 7, the first space 5 being the space within the operating handle 2, and the second space 7 being the space within the wiring harness tube 6 or the space within the insertion tube 1;

[0039] The cooling device further includes a pump 10 , which is connected in series to the circulation pipeline 8 and serves as a power element for circulating the heat medium in the circulation pipeline 8 . The pump 10 is disposed in the first space 5 or the second space 7 .

[0040] In the present scheme, the insertion tube 1 is a rod-shaped structure at the front end of the operating handle 2, and the front end of the insertion tube 1 serves as the insertion end of the endoscope when in use. The wire bundle tube 6 is a tubular structure at the rear end of the operating handle 2, and the rear end of the wire bundle tube 6 is connected to the main machine of the endoscope when in use, including the camera module, light source module, water and gas module, negative pressure suction module, etc. The operating handle 2 is a structure for medical staff to hold the endoscope body when in use. In the prior art, the AFE module of the electronic ultrasonic gastroscope is preposed to the operating handle 2; the operating handle 2 of the white light camera and the fluorescence camera handle is usually provided with an imaging module; the operating handle 2 of the light source preposed electronic gastroscope and electronic enteroscope has a light source module as a light source in addition to the action driving module. The above endoscope body assembly generates a lot of heat when in use, and when the operating handle 2 is held by medical staff for a long time, the surface temperature of the operating handle 2 can reach 40℃ or even above due to the covering of the outer wall of the operating handle 2. This not only causes the medical staff to have an uncomfortable feeling, but also affects the service life of the endoscope. In the technical solution provided in patent application No. CN201910815141.1, a cold fluid treatment is adopted, and the specific structure includes a fluid inlet and a fluid outlet. A wind cooling treatment is also provided, and the specific structure includes an air inlet and an air outlet.

[0041] The present scheme is aimed at the widely used endoscope, electronic gastroscope, electronic enteroscope, electronic ultrasonic gastroscope, etc. which have washing and disinfection performance requirements, and provides a technical solution that can better meet the sealing performance needs of the endoscope body assembly while solving the heat concentration problem of the operating handle 2, so as to ensure the cleaning and disinfection performance of the endoscope.

[0042] In the above scheme, specifically, the internal space of the circulation pipeline 8 is the heat carrier medium flow channel, and the pump 10 is connected in series on the circulation pipeline 8. When the pump 10 works, the pump 10 drives the heat carrier medium to circulate in the circulation pipeline 8. When the heat carrier medium flows through the first space 5, the heat in the first space 5 can be conducted to the heat carrier medium through the circulation pipeline 8 or through the heat absorption assembly 11 separately arranged on the circulation pipeline 8. When the heat-absorbed heat carrier medium flows through the second space 7, the heat of the heat carrier medium can be transferred to the second space 7 through the circulation pipeline 8 or through the heat release assembly 12 separately arranged on the circulation pipeline 8. Thus, according to the characteristics of the electronic wire harness, the fluid medium conduit, and the light guide medium that are generally arranged in the wire harness tube 6 and the insertion tube 1, the heat in the first space 5 can be transferred to the wire harness tube 6 and the insertion tube 1 through the cooling device. Thus, even if the surface of the operating handle 2 is poorly cooled because the operating handle 2 is held for a long time, the heat generated by the heat-generating component 3 in the first space 5 can be forcibly transferred to the wire harness tube 6 and the insertion tube 1 through the cooling device, so as to control the temperature rise of the surface of the operating handle 2 and the first space 5.

[0043] Meanwhile, in the present scheme, the heat is removed from the surface of the operating handle 2 and the first space 5 through the cooling device, and is only transferred to the second space 7 that does not affect the operation of the endoscope by medical staff and reduces the temperature of the heat-generating component 3. Therefore, in the present scheme, the principle of cooling or controlling the maximum temperature of the operating handle 2 is to transfer heat to expand the heat storage area and increase the heat dissipation area, and it is not necessary to arrange medium inlets and outlets for the cooling device on the surface of the endoscope body. Therefore, from the perspective of the sealing of the endoscope body, the present scheme is beneficial to guarantee the disinfection and cleaning performance of the endoscope, and can achieve the purpose of controlling the temperature of the surface and the inside of the operating handle 2 while guaranteeing the reliability of the endoscope.

[0044] Meanwhile, in the present scheme, the volume of the heat storage structure and the heat exchange area are increased through the cooling device. Thus, the heat distribution on the endoscope body assembly is uniformed, the temperature at the position of the operating handle 2 is reduced, and the heat can be transferred to the outside through other parts of the present assembly. Therefore, the present scheme will not cause obvious temperature changes in other parts.

[0045] As a person skilled in the art, the circulation pipeline 8 itself has heat transfer performance. Therefore, in the present scheme, the heat absorption and release of the heat carrier medium can be realized based on the circulation pipeline 8 as a heat conduction pipe. Such an implementation requires that the circulation pipeline 8 itself has good heat transfer capacity, which can be achieved by means such as material selection and wall thickness selection. Under the concept provided in the present scheme, the implementation of these means does not require creative labor.

[0046] To meet the requirements of the cooling device embedded in the endoscope lens assembly, the pump 10 in the prior art is a micro pump. Since the pump 10 itself becomes a heat source when it is working, the cooling device further comprises a temperature sensor arranged in the first space 5. When the temperature sensor detects that the temperature in the first space 5 is higher than a set threshold, the pump 10 is manually controlled or automatically triggered to work, so as to reduce the total heat generated during the use of the endoscope lens assembly. Further, to ensure the operation accuracy of the endoscope during use, the cooling device further comprises a prompt module outputting light or sound, so as to output light or sound in advance through the prompt module to remind the user to pay attention before the pump 10 is automatically triggered to work, so as to avoid the interference of the pump 10 on the operation accuracy of the endoscope.

[0047] As a person skilled in the art, the insertion tube 1, the operating handle 2 and the wire harness tube 6 are all hollow structures including the shell 4, and the first space 5 and the second space 7 are corresponding structure cavities.

[0048] Embodiment 2:

[0049] This embodiment is further refined on the basis of embodiment 1:

[0050] To facilitate the arrangement of the cooling device in the limited first space 5 and second space 7, preferably, the circulating pipeline 8 is a flexible pipe, and the pump 10 is arranged in the first space 5. In this scheme, the flexible pipe is used to adapt to the arrangement of the circulating pipeline 8 in the first space 5 and the second space 7, and the first space 5 has more idle space than the second space 7, which facilitates the arrangement of the pump 10.

[0051] Embodiment 3:

[0052] This embodiment is further refined on the basis of embodiment 1:

[0053] As described above, the circulating pipeline itself can be used as a heat transfer pipe to introduce the heat in the first space 5 into the second space 7 in a partitioned heat exchange manner, but this puts higher requirements on the selection of the circulating pipeline 8. To solve this problem, preferably, the circulating pipeline 8 is provided with a heat absorption assembly 11 arranged in the first space 5 and a heat release assembly 12 arranged in the second space 7.

[0054] Compared with the circulation pipeline 8, the heat absorption assembly 11 is used to strengthen the heat conduction capacity of the heat carrier medium and the peripheral environment of the heat absorption assembly 11, and the heat release assembly 12 is used to strengthen the heat conduction capacity of the heat carrier medium and the peripheral environment of the heat release assembly 12. In this scheme, it is easy to understand that the above heat absorption assembly 11 and the heat release assembly 12 can be the same structure or different structures. When they are the same structure, the reason for using different names is that when the structure is in different temperature environments, it will cause the heat carrier medium to absorb heat or release heat, so the relevant naming can be considered as only distinguishing the structure from the function. At the same time, as a person skilled in the art, the heat absorption assembly 11 and the heat release assembly 12 can be a pipe connected to the circulation pipeline 8, or a pipe segment different from other positions on the circulation pipeline 8.

[0055] As a specific implementation of the heat absorption assembly 11, the heat absorption assembly 11 is one or more of the following structures: a coil pipe connected in series with the circulation pipeline 8, a heat conduction plate mounted on the circulation pipeline 8, a branch pipe connected in series with the circulation pipeline 8, and a metal pipe segment connected in series with the circulation pipeline 8. The branch pipe is multiple, and the branch pipes are in parallel relationship with each other. When it is a coil pipe, in order to make the heat carrier medium have good heat absorption capacity, the coil pipe is wrapped around the heating component 3. When it is a heat conduction plate, the heat conduction plate can be mounted on the outer wall of the circulation pipeline 8, or the heat conduction plate can provide a heat carrier medium flow channel connected in series with the circulation pipeline 8. When it is a branch pipe, the branch pipe is a branch pipe on the circulation pipeline 8 to increase the heat absorption area of the circulation pipeline 8 in the first space 5. From the flow capacity and pressure bearing capacity of the heat carrier medium, the branch pipe can be thinner and thinner. It not only can be set to have better heat transfer adhesion quality with the heating component 3, but also can easily pass through the gaps on the heating component 3 and the gaps between the heating components 3, thereby expanding the direct heat absorption area of the circulation pipeline 8 in the first space 5. When it is a metal pipe segment, the metal pipe segment generally has a large heat transfer coefficient to ensure the heat absorption effect of the heat carrier medium in the first space 5.

[0056] As the same as the above heat absorption assembly 11, the heat release assembly 12 is one or more of the following structures: a coil pipe connected in series with the circulation pipeline 8, a heat conduction plate mounted on the circulation pipeline 8, a branch pipe connected in series with the circulation pipeline 8, and a metal pipe segment connected in series with the circulation pipeline 8. The branch pipe is multiple, and the branch pipes are in parallel relationship with each other. As a person skilled in the art, this scheme provides a specific implementation of the heat release assembly 12 from the heat dissipation of the heat carrier medium. The principle of heat dissipation of the heat carrier medium through the heat release assembly 12 is the same as the principle of heat absorption of the heat carrier medium through the heat absorption assembly 11.
