The image capture module comprises a camera module and a circuit board, the circuit board is accommodated in the receiving groove, the camera module is arranged at the insertion end and electrically connected to the circuit board, and the first end of the heat conductive member contacts the camera module. The heat dissipation pipe is arranged inside the hollow tube body, one end of the heat dissipation pipe contacts the heat conductive member, and the other end of the heat dissipation pipe extends in a direction away from the insertion end.

[0005] In summary, according to the endoscope device of the embodiment of the present invention, the heat conductive member contacts the camera module and the circuit board contacts the heat pipe assembly, so that the heat generated by the operation of the camera module and the circuit board can be conducted through the heat conductive member and the heat pipe, thereby preventing the part of the endoscope device that is extended into the human body from being overheated and causing damage, and also improving the use time of the endoscope device and the service life of its internal electronic components.

[0058] Various embodiments are provided below for detailed description. However, the embodiments are only used as examples and do not limit the scope of the invention. In addition, some elements are omitted in the drawings in the embodiments to clearly show the technical features of the invention. The same reference numerals will be used to represent the same or similar elements in all drawings.

[0059] Figure 1 is a stereoscopic diagram of a first embodiment of an endoscope device of the present invention, Figure 2is an exploded perspective view of a first embodiment of an endoscope device of the present invention, Figure 3 is another exploded perspective view of the first embodiment of the endoscope device of the present invention, Figure 4 for Figure 1 The cross-sectional view along line segment 4-4. Figures 1 to 4 As shown, the endoscope device 1 includes a hollow tube body 10 , a heat conducting member 20 , an image capturing module 30 and a heat dissipation pipe 40 , wherein the heat conducting member 20 , the image capturing module 30 and the heat dissipation pipe 40 are disposed in the hollow tube body 10 .

[0060] like Figures 1 to 4 As shown, the hollow tube 10 can be a rigid tube or a flexible tube. For example, the hollow tube 10 can be a hard plastic tube (such as a plastic tube or a rubber tube), a metal tube (such as an iron tube, a stainless steel tube, a copper tube, an aluminum tube or an alloy tube), a glass tube or other tubes with good thermal conductivity. Alternatively, the hollow tube 10 can also be a composite tube (for example, the hollow tube 10 can be a composite tube made of at least two materials of plastic, rubber, and metal).

[0061] like Figures 1 to 4 As shown, the hollow tube 10 includes an insertion end 11 and an operation end 13 opposite to each other, and the image capture module 30 includes a camera module 31 and a circuit board 32. The camera module 31 is disposed at the insertion end 11 and electrically connected to the circuit board 32. The user can extend the insertion end 11 of the hollow tube 10 into the human body to capture the image of the human body or observe the condition of the human body through the camera module 31 of the image capture module 30. In this embodiment, the hollow tube 10 is a round tube to facilitate insertion into the human body, but this is not limited, and the hollow tube 10 can also be an elliptical tube, a square tube, or a tube of other shapes.

[0062] like Figures 1 to 4 As shown, the heat conductive member 20 is disposed inside the hollow tube 10 and adjacent to the insertion end 11. The heat conductive member 20 includes a first end 21, a second end 22, a receiving groove 23 and a slot 24. The first end 21 is adjacent to the insertion end 11 of the hollow tube 10 relative to the second end 22. The receiving groove 23 is located between the first end 21 and the second end 22. The slot 24 is disposed at the second end 22. The circuit board 32 of the image capture module 30 is at least partially received in the receiving groove 23 to contact the inner surface of the heat conductive member 20. The first end 21 of the heat conductive member 20 contacts the camera module 31. In some embodiments, the heat conductive member 20 may be made of a material with good thermal conductivity, such as copper, aluminum or aluminum alloy with high thermal conductivity.

[0063] like Figures 1 to 4As shown, in this embodiment, the heat conducting member 20 is a column (here a cylinder, but not limited to), the receiving groove 23 is recessed on one side of the heat conducting member 20 and connected to the first end 21 and the second end 22, the receiving groove 23 and the slot 24 are not connected to each other, and the circuit board 32 may have a plurality of electronic components E1 to E3 (such as a microprocessor, a resistor, a capacitor or an oscillator, etc.), and the electronic components E1 to E3 are also located in the receiving groove 23 and indirectly contact the inner surface of the heat conducting member 20. Here, one end of the circuit board 32 further extends the first end 21 to be electrically connected to the camera module 31, and the other end of the circuit board 32 extends the second end 22 to be connected to a signal output circuit 80 (such as Figure 1 As shown), the image signal captured by the camera module 31 can be output to the outside through the signal output line 80. For example, the signal output line 80 can output the image signal to a display screen for display.

[0064] like Figures 1 to 4 As shown, the heat dissipation pipe 40 is disposed inside the hollow tube body 10, and one end of the heat dissipation pipe 40 is inserted into the slot 24 to contact the heat conductive member 20, and the other end of the heat dissipation pipe 40 extends in a direction away from the insertion end 11, wherein the other end of the heat dissipation pipe 40 can extend to the operating end 13, so that the length and heat dissipation area of ​​the heat dissipation pipe 40 are increased to improve the heat dissipation effect. In some embodiments, the heat dissipation pipe 40 can also be fixed and contacted with the heat conductive member 20 by other means, for example, the heat dissipation pipe 40 can be fixed and contacted with the heat conductive member 20 by bonding, snapping, abutting or welding, etc., and is not limited to the above-mentioned insertion into the slot 24.

[0065] In addition, the deeper the slot 24 of the heat conducting member 20 is, the larger the contact area between the heat pipe 40 and the heat conducting member 20 is, which can further improve the heat conduction effect. Figure 4 As shown, in the present embodiment, the depth of the slot 24 of the heat conductive member 20 is greater than half the length of the heat conductive member 20. For example, if the length of the heat conductive member 20 is 2 cm, the depth of the slot 24 of the heat conductive member 20 may be greater than 1 cm. Alternatively, the slot 24 of the heat conductive member 20 may also pass through the first end 21 and the second end 22 of the heat conductive member 20, so as to further increase the contact area between the heat pipe 40 and the heat conductive member 20.

[0066] In some embodiments, the heat pipe 40 may be made of a material with good thermal conductivity, such as copper, aluminum or aluminum alloy and other materials with high thermal conductivity. In addition, the heat pipe 40 may be a solid tube, or the heat pipe 40 may also be a heat pipe and include an evaporation end 41 and a condensation end 42 opposite to each other, wherein the heat pipe 40 is inserted into the slot 24 of the heat conductive member 20 with the evaporation end 41. For example, the heat pipe 40 includes a copper tube with an internal vacuum and a working fluid and a capillary structure arranged in the copper tube. When the evaporation end 41 is heated, the working fluid will evaporate into a vapor phase and flow toward the condensation end 42. The vapor phase working fluid flowing to the condensation end 42 will condense into a liquid phase after being cooled and be transferred back to the evaporation end 41 through the capillary structure. In this way, the absorption-release heat cycle operation can achieve the effect of rapid heat conduction and heat dissipation.

[0067] Thus, the first end 21 of the heat conductive member 20 contacts the camera module 31, the accommodating groove 23 of the heat conductive member 20 accommodates the circuit board 32 and contacts each other, and one end of the heat dissipation tube 40 contacts the heat conductive member 20. When the endoscope device 1 is in use, the heat generated by the electronic components E1 to E3 on the camera module 31 and the circuit board 32 during operation can be quickly transferred to the heat conductive member 20 and further dissipated through the heat dissipation tube 40, so as to avoid the part of the endoscope device 1 extending into the human body (for example, the part of the hollow tube 10 close to the insertion end 11) from being overheated and causing harm to the human body. In addition, the camera module 31 and the circuit board 32 are not easily overheated (for example, they can be maintained below 35° C. for a long time), which not only improves safety, but also prolongs the use time of the endoscope device 1 and increases the service life of the image capture module 30.

[0068] In some embodiments, the first end 21 of the heat conducting member 20 may directly or indirectly contact the camera module 31. Figure 4 As shown, in this embodiment, the first end 21 of the heat conductive element 20 is indirectly in contact with the camera module 31 via the heat conductive body 70, wherein the heat conductive body 70 may be a heat conductive glue or a heat conductive paste, so that the heat conductive element 20 and the camera module 31 can be conducted through the heat conductive body 70, and the heat conductive body 70 can also achieve the effect of fixing the heat conductive element 20 and the camera module 31. Alternatively, the heat conductive body 70 may also be a heat conductive sheet or a heat conductive silica gel to be sandwiched between the first end 21 of the heat conductive element 20 and the camera module 31 to avoid the heat conductive element 20 and the camera module 31 from being unable to contact each other due to manufacturing or assembly tolerances. Preferably, the heat conductive body 70 meets the functions of fixing and conducting heat energy at the same time, and the type and fixing mode are not limited to the above.

[0069] In some embodiments, the camera module 31 includes at least one lens 311 and at least one photosensitive element 312. Figure 4As shown, here, the photosensitive element 312 of the camera module 31 is electrically connected to the circuit board 32 (for example, the photosensitive element 312 can be electrically connected to the circuit board 32 through a conductive line), and the photosensitive element 312 maintains a predetermined distance from the lens 311, so that the external light can be focused on the photosensitive element 312 when entering from the lens 311. The first end 21 of the heat conductive element 20 contacts the photosensitive element 312, so that the heat generated by the photosensitive element 312 during operation can be conducted to the heat conductive element 20. For example Figure 2 As shown, in the present embodiment, the camera module 31 includes two lenses 311 (e.g., left and right lenses), and the two lenses 311 can capture left and right images respectively to synthesize a 3D image, but this is not limited, and the camera module 31 can also include only one lens 311. The photosensitive element 312 can specifically be a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), a complementary metal-oxide semiconductor active pixel sensor (CMOS Active pixels sensor) or a wafer-level image sensor, etc.

[0070] like Figures 1 to 4 As shown, in this embodiment, the image capture module 30 further includes a light source 33, which is disposed at the insertion end 11 of the hollow tube 10 as auxiliary lighting, so that the camera module 31 can obtain a clearer image by being illuminated by the light source 33. The first end 21 of the heat conductive member 20 further contacts the light source 33, so that the heat generated by the light source 33 during operation can be quickly transferred to the heat conductive member 20 and further transferred and dissipated through the heat pipe 40, so as to avoid the temperature of the part of the endoscope device 1 inserted into the human body being too high to cause damage, and also to increase the service life of the light source 33.

[0071] In some embodiments, the light source 33 may be an incandescent lamp, a halogen lamp, or an LED lamp. For example, the light source 33 may be a surface mounted LED, so that the light source 33 can be quickly mounted on the circuit board 32 by an automated machine, thereby significantly reducing labor and time costs.

[0072] In some embodiments, the heat conducting member 20 may also directly or indirectly contact the light source 33. Figure 4As shown, the heat conducting member 20 is indirectly in contact with the light source 33 via at least one heat conducting layer 71. In this embodiment, the light source 33 includes a plurality of light emitting members (here, two light emitting members 331), and the heat conducting member 20 is indirectly in contact with the two light emitting members 331 respectively via two heat conducting layers 71. The heat conducting layer 71 may be a heat conducting adhesive layer or a heat conducting paste layer, so that the heat conducting member 20 and the light source 33 can be conducted through the heat conducting layer 71, and the heat conducting layer 71 can also achieve the effect of fixing the heat conducting member 20 and the light source 33. Alternatively, the heat conducting layer 71 may also be a heat conducting sheet or a heat conducting silicone layer sandwiched between the heat conducting member 20 and the light source 33 to avoid the heat conducting member 20 and the light source 33 being unable to contact each other due to manufacturing or assembly tolerances.

[0073] For example Figures 1 to 4 As shown, in this embodiment, the first end 21 of the heat-conducting member 20 includes two heat-conducting columns 211 and a groove 212 between the two heat-conducting columns 211, and the camera module 31 is arranged corresponding to the groove 212, and the two light-emitting members 331 are arranged corresponding to the two heat-conducting columns 211. Since the volume of the camera module 31 is larger than the volume of the light source 33, the camera module 31 with a larger volume is accommodated in the groove 212, and the heat-conducting member 20 contacts the two light-emitting members 331 with the ends of the two heat-conducting columns 211. In this way, the heat-conducting area of ​​the heat-conducting member 20 can be increased (two heat-conducting columns 211 are added) and the configuration space inside the hollow tube 10 can be fully utilized.

[0074] For example Figure 4 As shown, the circuit board 32 is a flexible circuit board and includes a plurality of flexible thin film circuit layers (here, at least three thin film circuit layers 321a, 321b, 321c), and the plurality of thin film circuit layers 321a, 321b, 321c are stacked on each other and electrically connected to the camera module 31 and the light source 33, respectively. In this embodiment, two of the thin film circuit layers 321a and 321c of the circuit board 32 extend out of the first end 21 of the heat conductive member 20 and are electrically connected to the two light emitting members 331, respectively, and the thin film circuit layer 321b extends out of the first end 21 of the heat conductive member 20 and is electrically connected to the camera module 31. Thus, by making the circuit board 32 a flexible circuit board and being accommodated in the accommodation groove 23 in a stacked manner, more circuits and electronic components can be arranged in the limited space inside the hollow tube 10, the volume of the endoscope device 1 can be greatly reduced, and the assembly is more convenient.

[0075] like Figures 1 to 4As shown, the camera module 31 and the light source 33 can be assembled at the insertion end 11 of the hollow tube 10 through a cover 50. In this embodiment, the cover 50 is assembled at the insertion end 11 of the hollow tube 10, and the cover 50 includes a central assembly port 51 and two side assembly ports 52, and the two side assembly ports 52 are arranged around the central assembly port 51. Preferably, the camera module 31 is arranged at the central assembly port 51, and the two light-emitting components 311 of the light source 33 are respectively arranged at the two side assembly ports 52, but the actual configuration is not limited to this.

[0076] like Figure 3 As shown, the cover 50 has a first alignment portion 53, and the insertion end 11 of the hollow tube 10 has a second alignment portion 12. The first alignment portion 53 can be assembled correspondingly to the second alignment portion 12 to avoid the wrong assembly direction of the cover 50, which causes the camera module 31 to capture an erroneous image (for example, the captured image is upside down). In this embodiment, the first alignment portion 53 of the cover 50 is a protrusion, and the second alignment portion 12 of the insertion end 11 of the hollow tube 10 is a notch, but this is not limited to the present invention. The first alignment portion 53 and the second alignment portion 12 can be structures that can be assembled with each other.

[0077] like Figure 5 , which is a partial stereoscopic view of the first embodiment of the endoscope device of the present invention. In this embodiment, a heat conductive adhesive layer 72 is further filled between the heat dissipation pipe 40 and the slot 24 of the heat conductive member 20. For example, the heat conductive adhesive layer 72 can be a heat conductive glue or a heat conductive paste. Similar to the function of the heat conductive layer 71, in addition to heat conduction between the heat conductive member 20 and the heat dissipation pipe 40 through the heat conductive adhesive layer 72, the heat conductive adhesive layer 72 can also achieve the effect of fixing the heat conductive member 20 and the heat dissipation pipe 40.

[0078] For example Figure 5 As shown, in this embodiment, the slot 24 of the heat conducting member 20 includes an inner section 241 and an outer section 242, and the width of the inner section 241 is smaller than the width of the outer section 242, so that one end of the heat pipe 40 can be easily inserted from the outside to be assembled into the slot 24, thereby improving the convenience of assembly. In addition, during the assembly process, the thermal conductive glue or thermal conductive paste can be filled into the inner section 241 first, and when one end of the heat pipe 40 is inserted into the inner section 241, the thermal conductive glue or thermal conductive paste can flow to the outer section 242 with a larger width to fill the remaining gap, thereby avoiding overflowing from the outside of the slot 24.

[0079] like Figure 6 and Figure 7 2 is another exploded perspective view and another perspective view of the first embodiment of the endoscope device of the present invention. In this embodiment, the operating end 13 of the hollow tube 10 is further provided with a handle 60 for the user to hold the handle 60 for operation.

[0080] like Figure 6As shown, the handle 60 further has a first alignment member 61, and the operating end 13 of the hollow tube body 10 has a second alignment member 14, and the first alignment member 61 is correspondingly assembled to the second alignment member 14 to avoid the wrong assembly direction of the handle 60 and increase the efficiency of assembly. In this embodiment, the first alignment member 61 of the handle 60 is a block convexly arranged on the inner surface of the handle 60, and the second alignment member 14 of the operating end 13 of the hollow tube body 10 is a slot, but this is not limited, and the first alignment member 61 and the second alignment member 14 can be structures that can cooperate with each other for assembly.

[0081] like Figure 7 As shown, at least one marking portion is further provided on the handle 60, and the marking portion corresponds to the image capturing direction of the image capturing module 30, whereby the user can quickly know the image capturing direction of the image capturing module 30 through the marking portion when operating the endoscope device 1, thereby improving the efficiency of the operation. In this embodiment, three marking portions (two marking portions 62a and one marking portion 62b) are provided on the handle 60, and each marking portion 62a is an arrow pattern and faces the insertion end 11 of the hollow tube 10 to indicate the image capturing direction of the image capturing module 30, but this is not limited. In some embodiments, each marking portion 62a can also be a pattern such as a marking line, a punctuation point, a marking symbol, a marking graphic or a marking text, and each marking portion 62a can be fixed on the surface of the handle 60 by printing or pasting, or each marking portion 62a can also be an integrally formed structure with the handle 60. In addition, the image capturing direction of each marking portion 62 a corresponding to the image capturing module 30 may refer to that the setting direction of the marking portion 62 a and the image capturing direction are the same direction or the opposite direction, which is not limited thereto.

[0082] For example Figure 7 As shown, in this embodiment, the marking portion 62b of the handle 60 is a surface texture. For example, in this embodiment, the marking portion 62b is a linear groove texture, but this is not limited. In some embodiments, the marking portion 62b can also be a convex texture or a groove texture of other shapes. The setting direction of each marking portion 62b can also be the same direction or the opposite direction to the image capture direction. Thus, when the user holds the handle 60, the image capture direction of the image capture module 30 can be known by the touch of the marking portion 62b.

[0083] like Figure 2 and Figure 4As shown, in this embodiment, an insulating sleeve 15 is further disposed inside the hollow tube 10, wherein the insulating sleeve 15 can be a tube made of insulating material. In some embodiments, the insulating material can be an inorganic insulating material (such as ceramics, asbestos), an organic insulating material (such as resin, rubber, silk cotton, paper) or a composite insulating material made of the above two insulating materials. At least a portion of the heat dissipation pipe 40 is located in the insulating sleeve 15 to prevent the heat dissipation pipe 40 and the hollow tube 10 from contacting each other and affecting the heat dissipation effect, and also to prevent the endoscope device 1 from generating static electricity.

[0084] like Figure 8 and Fig. 9 2 is an exploded perspective view and a cross-sectional view of a second embodiment of an endoscope device of the present invention. The endoscope device 2 of this embodiment differs from the first embodiment at least in that the receiving groove 23a of the heat-conducting member 20a of the endoscope device 2 includes a first groove 231 and a second groove 232, and the first groove 231 and the second groove 232 are respectively recessed on different sides of the heat-conducting member 20a. Here, the first groove 231 and the second groove 232 are at least partially connected, the first groove 231 is connected to the first end 21 of the heat-conducting member 20a, and the second groove 232 is connected to the second end 22 of the heat-conducting member 20a. The camera module 31a of the image capture module 30a includes a single lens 311a and a photosensitive element 312a corresponding to the lens 311a, and the circuit board 32a of the image capture module 30a is accommodated in the second groove 232. One end of the circuit board 32a extends out of the first end 21 through the first groove 231 to be electrically connected to the image capture module 30a, and the other end of the circuit board 32a extends out of the second end 22. In this way, the circuit board 32a has a bendable characteristic and is bent on the first groove 231 and the second groove 232, so that the space can be more effectively utilized and the heat conduction capacity of the heat-conducting member 20a can be brought into play to the best effect.

[0085] For example Figure 8 and Fig. 9 As shown, since the camera module 31a of the image capture module 30a only includes a single lens 311a to reduce the overall volume, in this embodiment, a heat-conducting ring 25 is further set on the outside of the lens 311a of the camera module 31a, and the heat-conducting ring 25 contacts the two heat-conducting columns 211 of the heat-conducting member 20a, so that the lens 311a indirectly contacts the two heat-conducting columns 211 through the heat-conducting ring 25 to transfer the heat generated during operation to the heat-conducting member 20a. In some embodiments, the heat-conducting ring 25 can be a heat-conducting glue layer or a heat-conducting paste layer, so that the heat-conducting member 20a and the lens 311a can be transferred through the heat-conducting ring 25. In addition, the heat-conducting ring 25 can also achieve the effect of fixing the heat-conducting member 20a and the lens 311a. Alternatively, the heat-conducting ring 25 can also be a heat-conducting sheet or a heat-conducting silicone layer to be sandwiched between the heat-conducting member 20a and the lens 311a, which is not limited to this.

[0086] The same or similar elements in the endoscope device 1 of the first embodiment and the endoscope device 2 of the second embodiment are denoted by the same reference numerals and are described here first.

[0087] In summary, according to the endoscope device of the embodiment of the present invention, the heat conductive member contacts the camera module and the circuit board contacts the heat pipe assembly, so that the heat generated by the operation of the camera module and the circuit board can be conducted through the heat conductive member and the heat pipe, thereby preventing the part of the endoscope device that is extended into the human body from being overheated and causing damage, and also improving the use time of the endoscope device and the service life of its internal electronic components.
