[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any variation thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0023] Please also read Figure 1 and Figure 2 , Figure 1 is a schematic cross-sectional view of a first viewing angle of an endoscope camera head 100 in an embodiment of the present application, Figure 2 FIG. 1 is a schematic diagram of the overall structure of an endoscope camera head 100 in an embodiment of the present application. Figure 1 and Figure 2 As shown, the endoscope camera head 100 includes an operating part 10, a lens part 20 and a cable connecting part 30 (i.e., a communication connecting part), wherein the operating part 10 is arranged between the lens part 20 and the cable connecting part 30, wherein an optical imaging component 11 is arranged in the operating part 10, and the endoscope camera head 100 further includes a heat conducting member 40, wherein the heat conducting member 40 is arranged between at least one of the lens part 20 and the cable connecting part 30 and the optical imaging component 11 of the operating part 10, and is used for conducting the heat emitted by the optical imaging component 11 to at least one of the lens part 20 and the cable connecting part 30, and dissipating the heat through at least one of the lens part 20 and the cable connecting part 30.

[0024] It should be noted that in the embodiment of the present application, the communication connection part can be a cable connection part or a wireless communication connection part. When the communication connection part is a cable connection part, it is connected to the camera host through a physical cable and transmits the image data to the camera host for processing; when the communication connection part is a wireless communication connection part, it transmits the image data to the camera host for processing through wireless data transmission. Of course, the following description only takes the cable connection part as an example, and does not limit the communication connection part to only the cable connection part.

[0025] Therefore, in the present application, the heat generated by the optical imaging component 11, which is the main heat source of the endoscope camera head 100, is conducted to at least one of the lens head 20 and the cable connection part 30, thereby effectively reducing or even avoiding the problem of the operation part 10 heating up due to the heat generated by the optical imaging component 11 being conducted to the operation part 10, so that the user can continue to hold the operation part 10 for a long time to operate. Among them, the operation part 10 is the main part to hold when using the endoscope camera head 100. Through the structural improvement of the present application, the heat generated by the optical imaging component 11 will hardly be conducted to the operation part 10, so that the user can continue to hold the operation part 10 for a long time to operate when using the endoscope camera head 100, which improves the user experience and can effectively improve the treatment effect on the patient.

[0026] Among them, the first viewing angle in the present application is the viewing angle of the cross-section of the operating part 10, the lens part 20 and the cable connecting part 30 when they are cut along the arrangement direction of the operating part 10, the lens part 20 and the cable connecting part 30 and viewed at the same time.

[0027] See also Figure 3 , is a structural block diagram of the optical imaging component 11, the optical imaging component 11 includes an image sensor 111 and an image processor 112, and the heat dissipated by the optical imaging component 11 includes the heat dissipated by the image sensor 111 and / or the image processor 112.

[0028] One end of the heat conducting member 40 is disposed on at least one of the lens portion 20 and the cable connecting portion 30 , and the other end is close to or in contact with the image sensor 111 and / or the image processor 112 of the optical imaging assembly 11 .

[0029] As the imaging accuracy of the endoscope camera 100 is improved, the workload of the image sensor 111 for photoelectric conversion and the image processor 112 for imaging processing will be significantly increased, resulting in the generation of more heat, which has become the main heat source of the endoscope camera 100. The heat generated by the image sensor 111 and / or the image processor 112 is conducted to at least one of the lens unit 20 and the cable connection unit 30 through the heat conduction member 40, effectively preventing the heat from being conducted to the operating unit 10 and causing the temperature of the operating unit 10 to rise.

[0030] like Figure 1 and Figure 2As shown, the lens head 20 includes a lens barrel 21, a focusing knob 22 and a lens buckle 23 arranged around the lens barrel 21, and the heat conduction member 40 is connected between the lens barrel 21 of the lens head 20 and the optical imaging component 11 of the operating part 10, and is used to conduct the heat dissipated by the optical imaging component 11 to the lens barrel 21 of the lens head 20, and then conduct it to the focusing knob 22 and / or the lens buckle 23 through the lens barrel 21 for dissipation.

[0031] That is, in some embodiments, when the heat conduction member 40 is disposed between the lens head 20 and the optical imaging component of the operating part, one end of the heat conduction member 40 can extend to the lens barrel 21 of the lens head 20 and be close to or in contact with the lens barrel, and the other end of the heat conduction member 40 is close to or in contact with the optical imaging component 11 of the operating part 10, for example, close to or in contact with the image sensor 111 and / or the image processor 112 of the optical imaging component 11, so that the heat dissipated by the optical imaging component 11 can be conducted to the lens barrel 21 of the lens head 20, and then conducted to the focusing knob 22 and the lens buckle 23 through the lens barrel 21 for dissipation.

[0032] When the heat conducting member 40 is connected between the lens barrel 21 of the lens unit 20 and the optical imaging component 11 of the operating unit 10, the lens barrel 21 itself is made of a heat conducting material, for example, a heat conducting metal such as iron, copper or other heat conducting alloys, and the heat conducted to the lens barrel 21 by the heat conducting member 40 can be further conducted to the focusing knob 22 and the lens buckle 23 for dissipation.

[0033] In this application, the heat conduction member 40 is connected between two components, which means that the heat conduction member 40 realizes heat conduction between the two components, and the heat conduction member 40 can be arranged close to or in contact with the two components. For example, the heat conduction member 40 is connected between the lens barrel 21 of the lens head 20 and the optical imaging component 11 of the operating part 10, which means that the heat conduction member 40 realizes heat conduction connection between the lens barrel 21 of the lens head 20 and the optical imaging component 11 of the operating part 10, and the two ends of the heat conduction member 40 can be respectively in contact with or close to the lens barrel 21 and the optical imaging component 11.

[0034] See also Figure 4 , is a cross-sectional schematic diagram of a first viewing angle of an endoscope camera head 100 in another embodiment of the present application. Figure 4As shown, the lens head 20 also includes a heat conductive member 24 disposed on the lens barrel 21, and the heat conductive member 40 is connected between the heat conductive member 24 and the optical imaging component 11, and is used to conduct the heat dissipated by the optical imaging component 11 to the heat conductive member 24, and then conduct the heat to the focusing knob 22 and / or the lens buckle 23 through the heat conductive member 24 for dissipation.

[0035] That is, in some embodiments, a heat conductor 24 is additionally provided on the lens barrel 21, and the heat conductor 40 is connected between the heat conductor 24 and the optical imaging component 11 to conduct the heat dissipated by the optical imaging component 11 to the heat conductor 24, and then conduct the heat to the focusing knob 22 and / or the lens buckle 23 through the heat conductor 24 for dissipation.

[0036] like Figure 4 As shown, the heat conducting member 24 is disposed on the outer surface of the lens barrel 21 and is located between at least one of the focusing knob 22 and the lens buckle 23 and the lens barrel 21 .

[0037] For example, the heat conductive member 24 may include or may be a metal sheet, and the metal sheet is disposed between the lens barrel 21 and at least one of the focus knob 22 and the lens buckle 23 .

[0038] like Figure 4 As shown, the heat conducting member 24 which is a metal sheet can surround the outer surface of the lens barrel 21 to form a metal tube or a metal ring, thereby increasing the heat conducting area.

[0039] Obviously, in some embodiments, the heat conducting member 24 which is a metal sheet may also be disposed only on a partial arc surface area of ​​the outer surface of the lens barrel 21 , without forming an annular structure surrounding the lens barrel 21 .

[0040] The heat conducting member 24 may be a metal ring disposed in a partial area of ​​the lens barrel 21. In some embodiments, the heat conducting member 24 may also be a heat conducting metal cylinder that completely wraps the outer surface of the lens barrel 21.

[0041] in, Figure 4 The cross-sectional diagram shown is compared Figure 1 The more simplified schematic diagram is only for illustrating the heat-conducting member 24 disposed on the outer surface of the lens barrel 21 . All the drawings of the present application are only schematic diagrams and are simplified compared with the actual structure of the product.

[0042] Among them, Figure 4 In the illustrated embodiment, since the lens barrel 21 is not located in the heat conduction path, the lens barrel 21 can be made of lightweight materials such as plastic and resin, and does not need to be made of metal materials such as iron and copper. This can reduce the overall weight of the endoscope camera 100, reduce the burden of holding, and effectively reduce user fatigue.

[0043] See also Figure 5 , is a schematic cross-sectional view of the lens barrel 21 at a first viewing angle of the endoscope camera head 100 in one embodiment of the present application. Figure 5 As shown, a receiving groove C1 penetrating or not penetrating the wall of the lens barrel 21 is formed on the wall of the lens barrel 21 , and the heat conducting member 24 comprises a metal strip disposed in the receiving groove C1 .

[0044] Thus, in some embodiments, a heat conductor 24 is provided in the wall of the lens barrel 21, and the heat conductor 40 is connected between the heat conductor 24 and the optical imaging component 11 to conduct the heat dissipated by the optical imaging component 11 to the heat conductor 24, and then conduct the heat to the focusing knob 22 and / or the lens buckle 23 through the heat conductor 24 for dissipation.

[0045] In some embodiments, the receiving groove C1 may be an annular groove or an arc groove arranged around the lens barrel 21. That is, the receiving groove C1 may be a closed annular groove surrounding the lens barrel 21, or a spiral annular groove surrounding the lens barrel 21 for at least two times. The metal strip is correspondingly an annular metal strip surrounding the lens barrel 21 for at least one time, and the shape of the metal strip is adapted to the receiving groove C1 and is accommodated in the receiving groove C1. In some embodiments, the receiving groove C1 may also be an arc groove surrounding half of the lens barrel 21.

[0046] In some embodiments, the number of the receiving grooves C1 may be multiple, and the heat conducting member 24 includes multiple metal strips disposed in the multiple receiving grooves C1.

[0047] The plurality of metal strips may be interconnected or independent of each other, and the number of heat conducting members 40 connected between the heat conducting member 24 and the optical imaging component 11 may be multiple, respectively connected between the plurality of metal strips and the optical imaging component 11 .

[0048] Among them, when a receiving groove C1 is opened on the wall of the lens barrel 21 and penetrates the wall, the heat dissipated by the optical imaging component 11 can be conducted to the focusing knob 22 and / or the lens buckle 23 only through the heat conductor 24 for dissipation. At this time, the lens barrel 21 can be made of lightweight materials such as plastic and resin, and there is no need to use metal materials such as iron and copper, thereby reducing the overall weight of the endoscope camera 100, reducing the burden of holding, and effectively alleviating the user's fatigue.

[0049] See also Figure 6 , is a cross-sectional schematic diagram of a first viewing angle of an endoscope camera head 100 in other embodiments of the present application. Figure 6As shown, the operating part 10 includes a shell K1, and the lens part 20 includes a shell K2. A first thermal isolation member 50 is also provided between the shell K1 of the operating part and the shell K2 of the lens part 20 to prevent the heat conducted to the lens part 20 from being transferred back to the operating part 10.

[0050] like Figure 6 As shown, the housing K1 of the operating unit 10 is a structure with two ends open, and a receiving space is formed in the housing K1. The optical imaging assembly 11 is received in the receiving space in the housing K1. The lens barrel 21 of the lens unit 20 and the focus knob 22 and the lens buckle 23 arranged around the outside of the lens barrel 21 can be combined to form the housing K2 of the lens unit 20. The housing K2 of the lens unit 20 is also a structure with two ends open, and cooperates with the housing K1 of the operating unit 10 to form a connected space.

[0051] The focus knob 22 is located between the lens buckle 23 and the operating portion 10 , and the first isolation member 50 is specifically disposed between the housing of the operating portion 10 and the focus knob 22 .

[0052] That is, in any of the aforementioned embodiments, a first thermal isolation component 50 may be further provided between the lens unit 20 and the housing of the operating unit 10 to thermally isolate the housing K2 of the lens unit 20 from the housing K1 of the operating unit 10, so that the heat of the optical imaging component 11 in the operating unit 10 cannot be transferred back to the operating unit 10 after being transferred to the lens unit 20 via the heat conduction component 40, thereby further ensuring that the temperature of the operating unit 10 does not rise excessively due to the heat of the optical imaging component 11.

[0053] The first thermal isolation member 50 may be sandwiched between the housing K2 of the lens unit 20 and the housing K1 of the operating unit 10 , and cooperate with the housing K2 of the lens unit 20 and the housing K1 of the operating unit 10 to form a sealing structure.

[0054] The first thermal isolation member 50 may be a thermal insulation member made of a material with poor thermal conductivity, for example, a thermal insulation member made of ceramic or other materials.

[0055] As mentioned above, the lens head 20 and the operating part 10 are both hollow cylindrical structures for accommodating corresponding components. The first thermal isolation member 50 may be an annular structure to thermally isolate the lens head 20 from the housing of the operating part 10 as a whole.

[0056] Please return to Figure 1 ,like Figure 1As shown, the cable connecting part 30 includes a connecting part 31 made of metal material, which is used to be fixedly connected to the cable 32. The heat conducting part 40 is connected between the connecting part 31 and the optical imaging component 11 of the operating part 10, and is used to conduct the heat dissipated by the optical imaging component 11 to the connecting part 31 and dissipate it through the connecting part 31.

[0057] The connecting member 31 may be made of metal, and the inner diameter of the connecting member 31 may be equal to or slightly larger than the outer diameter of the cable 32 , so as to stably clamp and protect the cable 32 .

[0058] In other embodiments, the cable connecting portion 30 may include a connecting piece 31 made of a metal material and an end of a cable 32 fixedly connected to the connecting piece. That is, in other embodiments, the cable connecting portion 30 refers to a component including the connecting piece 31 and the end of a cable 32 fixedly connected to the connecting piece.

[0059] Among them, a metal shielding mesh is provided on the inner surface of the end of the cable 32, and the heat conduction member 40 is connected between the metal shielding mesh at the end of the cable 32 and the optical imaging component 11 of the operating part 10, and is used to conduct the heat dissipated by the optical imaging component 11 to the metal shielding mesh, and then conduct it to the outside of the cable 32 through the metal shielding mesh for dissipation.

[0060] That is, when the heat conduction member 40 is connected between the cable connection part 30 and the optical imaging component 11 of the operating part 10, the heat conduction member 40 can be specifically connected between the connection member 31 for fixed connection with the cable 32 and the optical imaging component 11 of the operating part 10, and the heat conduction member 40 can also be specifically connected between the metal shielding mesh in the end portion where the cable 32 is connected to the connection member 31 and the optical imaging component 11 of the operating part 10.

[0061] Obviously, in some embodiments, the heat conduction member 40 may be multiple, for example, two, respectively connected between the connecting member 31 and the optical imaging component 11 of the operating part 10, and between the metal shielding mesh at the end of the cable 32 and the optical imaging component 11 of the operating part 10.

[0062] In some implementations, there may be multiple heat conduction members 40 connected between the lens unit 20 and the optical imaging component 11 of the operating unit 10, such as multiple metal belts, which are respectively connected to different parts of the lens barrel 21 of the lens unit 20 and different parts of the optical imaging component 11 to form multiple heat conduction paths, thereby improving the heat conduction efficiency.

[0063] Among them, there may be multiple heat conduction components 40 connected between the connecting component 31 and the optical imaging component 11 of the operating part 10, and there may be multiple heat conduction components 40 connected between the metal shielding net at the end of the cable 32 and the optical imaging component 11 of the operating part 10, which can also form multiple heat conduction paths to improve the heat conduction efficiency.

[0064] like Figure 6 As shown, a second heat isolating member 60 is further disposed between the cable connecting portion 30 and the housing of the operating portion 10 , for preventing the heat conducted to the cable connecting portion 30 from being transferred back to the operating portion 10 .

[0065] The second thermal isolation member 60 may be a thermal insulation member made of a poorly conductive material, such as ceramics.

[0066] The connector 31 and / or the cable 32 in the cable connector 30 are both hollow cylindrical structures, and the second thermal isolation member 60 is also an annular structure, so as to thermally isolate the cable connector 30 from the shell of the operating unit 10 as a whole.

[0067] See also Figure 7 , is a cross-sectional schematic diagram of the operating portion 10 of the endoscopic camera 100 in an embodiment of the present application at a second viewing angle. In some embodiments, the endoscopic camera 100 also includes a thermal isolation tube 12 disposed in the operating portion 10, and the thermal isolation tube 12 is a hollow structure with openings at both ends. The optical imaging component 11 is accommodated in the thermal isolation tube 12, and the thermal isolation tube 12 is used to thermally isolate the optical imaging component 11 from the shell K1 of the operating portion 10.

[0068] That is, the heat isolation tube 12 is accommodated in the accommodation space formed by the shell K1 of the operating part 10 . The heat isolation tube 12 with a hollow structure has its own accommodation space to accommodate the optical imaging component 11 .

[0069] The second viewing angle is perpendicular to the first viewing angle, and is a viewing angle of a cross section of the operating portion 10 when the operating portion 10 is cut along a direction perpendicular to the lens portion 20 , the operating portion 10 and the cable connecting portion 30 .

[0070] The thermal isolation tube 12 is connected to the lens unit 20 and the cable connection unit 30 respectively, thereby forming corresponding optical paths and data transmission channels. For example, the optical imaging component 11 receives the optical signal transmitted from the lens unit 20 through the open end of the thermal isolation tube 12 adjacent to the lens unit 20, and the image sensor 111 of the optical imaging component 11 converts the optical signal into an electrical signal. The image processor 112 generates image data according to the electrical signal and transmits it to the cable connection unit 30, and then transmits it to the host 201 (such as the host 201) through the cable connection unit 30. Fig. 9 shown).

[0071] The thermal isolation tube 12 is made of a thermal insulation material, and the thermal insulation material may be a material with low thermal conductivity and / or low thermal radiation coefficient, such as a ceramic material.

[0072] The projection area of ​​the thermal isolation tube 12 on the shell of the operating part 10 includes the projection area of ​​the optical imaging component 11 on the shell of the operating part 10. That is, the projection area of ​​the optical imaging component 11 on the shell of the operating part 10 is located within the projection area of ​​the thermal isolation tube 12 on the shell of the operating part 10. Therefore, there is no directly facing area between the optical imaging component 11 and the shell of the operating part 10. The thermal isolation tube 12 is used to thermally isolate the optical imaging component 11 from the shell of the operating part 10, which can effectively avoid or reduce the heat generated by the optical imaging component 11 from being transferred to the shell of the operating part 10, so that the temperature of the shell of the operating part 10 will not increase due to the heat generated by the optical imaging component 11, or at least the impact of the heat generated by the optical imaging component 11 will be greatly reduced.

[0073] In some embodiments, the operating unit 10 further includes a heat insulating layer disposed between the optical imaging assembly 11 and the heat isolation cylinder 12. The heat insulating layer may include a two-layer structure, specifically, a plastic paper layer with low insulation thermal conductivity and a copper foil layer.

[0074] The thermal insulation layer may be formed on the inner wall of the thermal isolation tube 12 , or may be wrapped on the outer surface of the optical imaging component 11 .

[0075] Among them, when the thermal insulation layer is formed on the inner wall of the thermal isolation tube 12, the plastic paper layer with low insulation thermal conductivity of the thermal insulation layer is attached to the inner wall of the thermal isolation tube 12 as an inner layer, and the copper foil layer is located on the side away from the inner wall of the thermal isolation tube 12 as an outer layer. When the thermal insulation layer is wrapped around the outer surface of the optical imaging component 11, the plastic paper layer with low insulation thermal conductivity of the thermal insulation layer is attached to the outer surface of the optical imaging component 11 as an inner layer, and the copper foil layer is located on the side away from the outer surface of the optical imaging component 11 as an outer layer.
