[0067] See also Figures 1 to 4 , Figure 1 FIG. 1 is a schematic diagram of the appearance of an endoscope device 1 according to a first embodiment of the present invention. Figure 2A and Figure 2B FIG. 1 is a schematic diagram of a part of the internal structure of the endoscope device 1 according to the first embodiment of the present invention. Figure 3 and Figure 4 1 is an exploded view of some components of the endoscope device 1 according to the first embodiment of the present invention at different viewing angles. Figures 1 to 4As shown, the endoscope device 1 includes an insertion tube 11, an imaging assembly 12, a light guide 13 and a light emitting member 14. The insertion tube 11 includes a distal end 111 and a proximal end 112 relative to the distal end 111, wherein the proximal end 112 of the insertion tube 11 can be connected to an operating handle, and the distal end 111 of the insertion tube 11 can be inserted into the patient's body. The imaging assembly 12 includes a lens group 121 and an image sensor 122, wherein the lens group 121 is located near the distal end 111 of the insertion tube 11 and is used to guide external light to the image sensor 122, and the image sensor 122 is located in the insertion tube 11 and is engaged with the lens group 121. The light guide 13 is located near the distal end 111 of the insertion tube 11 and next to the lens group 121 to guide the light emitted by the light emitting member 14 into the patient's body. The light guide 13 includes an outer end 131 near the distal end 111 of the insertion tube 11 and an inner end 132 relative to the outer end 131. The length of the light guide 13 is greater than the length of the imaging component 12. The light emitting member 14 is located in the insertion tube 11 and near the inner end 132 of the light guide 13 to emit light toward the light guide 13.

[0068] Specifically, the light emitting member 14 may be located on a side of the image sensor 122 away from the distal end 111 of the insertion tube 11 , and the inner end 132 of the light guide 13 may protrude beyond the image sensor 122 along the length direction L of the insertion tube 11 toward the proximal end 112 of the insertion tube 11 .

[0069] The above configuration allows the section of the insertion tube 11 for accommodating the imaging assembly 12 to be closer to the tip portion of the distal end 111 of the insertion tube 11 than the section of the insertion tube 11 for accommodating the light emitting member 14, that is, the section of the insertion tube 11 for accommodating the imaging assembly 12 is located in front of the section of the insertion tube 11 for accommodating the light emitting member 14, so the present invention can significantly reduce the predetermined size (e.g., diameter) of the distal end 111 of the insertion tube 11. In addition, the above configuration also allows the light emitting member 14 to have a larger size without being interfered with by the imaging assembly 12, thereby providing bright lighting.

[0070] Preferably, the light emitting surface of the outer end 131 of the light guide 13 through which the light exits may have a texture that is beneficial to light diffusion.

[0071] Preferably, the light incident surface of the inner end 132 of the light guide 13 for receiving the light emitted by the light emitting element 14 may be polished to avoid reflection of the light emitted by the light emitting element 14 , thereby increasing the amount of light entering the light guide 13 .

[0072] Preferably, an optical film layer covering the surface of the side portion 133 of the light guide 13 may be provided on the surface of the side portion 133 of the light guide 13 by a coating or plating technology, wherein the refractive index of the material of the optical film layer is smaller than the refractive index of the material of the light guide 13 to prevent light from being refracted when passing through the surface of the side portion 133 of the light guide 13.

[0073] Preferably, the light guide 13 can be an optical fiber bundle, or a light guide column made of materials such as polycarbonate (PC), cycloolefin copolymer (COC), polymethylmethacrylate (PMMA) or liquid silicone rubber (LSR), and the refractive index of the material of the optical film layer can be 1.2 to 1.5.

[0074] Preferably, the light emitting element 14 may include one or more light emitting diodes (LEDs).

[0075] Preferably, the image sensor 122 may be a complementary metal oxide semiconductor (CMOS) sensor.

[0076] Preferably, the distal end 111 of the insertion tube 11 may be filled with a waterproof adhesive 1111 to prevent external fluid from entering the insertion tube 11 through the distal end 111 of the insertion tube 11, wherein the light-emitting surface of the outer end 131 of the light guide 13, the outer end of the lens group 121, the light-emitting surface of the light-emitting component 14 and the inner end 132 of the light guide 13 should be prevented from being contaminated by the waterproof adhesive 1111.

[0077] like Figure 2A and Figure 3 to Figure 4 As shown, in this embodiment, the light emitting element 14 generates heat while emitting light, so the light emitting element 14 can be used as a heating element, but the present invention is not limited to this embodiment. For example, in another embodiment, the heating element can be a processor or other electronic components. In order to quickly dissipate the heat generated by the light emitting element 14, the endoscope device 1 further includes an auxiliary element 15 and a heat dissipation pin 16. The auxiliary element 15 is located near the light emitting element 14, and the heat dissipation pin 16 is partially embedded in the auxiliary element 15.

[0078] Preferably, the heat sink 16 is made of copper.

[0079] Specifically, the light emitting member 14 is partially surrounded by the auxiliary member 15 so that the heat generated by the light emitting member 14 can be effectively radiated through the auxiliary member 15 .

[0080] Furthermore, if Figure 2A and Figure 3 to Figure 4 As shown, in this embodiment, the endoscope device 1 further includes a holding member 17 detachably engaged with the auxiliary member 15 and used to fix the light guide member 13 and the imaging assembly 12 .

[0081] Specifically, a first auxiliary structure 151 is formed at the first end of the auxiliary component 15 close to the proximal end 112 of the insertion tube 11, and two second auxiliary structures 152 are formed at the second end of the auxiliary component 15 relative to its first end. The first auxiliary structure 151 is used to accommodate the portion of the heat dissipation pin 16 exposed from the auxiliary component 15, and the two second auxiliary structures 152 are used to engage the retaining component 17.

[0082] Preferably, the first auxiliary structure 151 may be a recessed structure, and the second auxiliary structure 152 may be a notch structure.

[0083] In addition, the retaining member 17 includes two retaining portions 171 and a middle portion 172 disposed between the two retaining portions 171 . The two retaining portions 171 are used to be detachably engaged with the two second auxiliary structures 152 , and the light guide member 13 and the imaging assembly 12 are at least partially located in the space defined between the two retaining portions 171 .

[0084] Understandably, in another embodiment, the number of the second auxiliary structure for engaging the holder may be only one, and the holder may only be used to provide a receiving recess capable of fixing one of the light guide 13 and the imaging assembly 12. Alternatively, the holder may be omitted, or integrally connected to the auxiliary member.

[0085] In addition, if Figures 2A to 4 As shown, the endoscope device 1 further includes a heat dissipation tube 18, which is at least partially located in the insertion tube 11 and is coaxially arranged with the insertion tube 11. The heat dissipation tube 18 is located on the side of the remote end 111 of the light-emitting component 14 away from the insertion tube 11, and the auxiliary component 15 is at least partially arranged between the heat dissipation tube 18 and the light-emitting component 14.

[0086] Preferably, the material of the heat dissipation pipe 18 may be copper, and the material of the extension pipe 11 may be stainless steel.

[0087] Preferably, if Figure 2B As shown, the heat sink tube 18 extends toward a proximal end 112 of the tube.

[0088] In order to improve the heat dissipation efficiency, the space between the heat dissipation pipe 18 and the heat dissipation pin 16 and the space between the heat dissipation pipe 18 and the auxiliary component 15 are filled with heat dissipation glue to form a heat dissipation glue structure 19 .

[0089] Understandably, in another embodiment, the heat dissipation adhesive may be filled in only one of the space between the heat dissipation pipe and the heat dissipation pin and the space between the heat dissipation pipe and the auxiliary member. Alternatively, in another embodiment, the heat dissipation pin may be omitted, and the heat dissipation adhesive may be filled between the heat dissipation pipe and the auxiliary member.

[0090] The above-mentioned heat dissipation configuration can quickly transfer the heat generated by the light-emitting component 14 to the heat dissipation pipe 18 via the auxiliary component 15, the heat dissipation pin 16 and the heat dissipation adhesive structure 19, so as to achieve a significant temperature control effect, thereby preventing the light-emitting component 14, the image sensor 122 or other electronic components from being negatively affected by high temperature, and preventing the patient from being burned by high temperature.

[0091] In addition, if Figure 2A and Figure 3 to Figure 4 As shown, the endoscope device 1 further includes a first circuit board C1 electrically connected to the light-emitting element 14 and a second circuit board C2 electrically connected to the image sensor 122. The first circuit board C1 and the second circuit board C2 are separated from each other and are at least partially accommodated in a channel 153 of the auxiliary element 15 located on the bottom side thereof. A remote portion C11 of the first circuit board C1 is bent relative to the length direction L, and a remote portion C21 of the second circuit board C2 protrudes beyond the auxiliary element 15 toward the remote end 111 of the insertion tube 11 along the length direction L and is at least partially accommodated in a channel 173 of the holding element 17 located on the bottom side of the middle portion 172 thereof. The first circuit board C1 and the second circuit board C2 are at least covered by the heat dissipation adhesive structure 19.

In addition, in this embodiment, the top of the light emitting element 14' is not covered by an auxiliary element 15', and the auxiliary element 15' includes a first channel 151' and a second channel 152' opposite to the first channel 151'. In addition, in this embodiment, a first circuit board C1' electrically connected to the light emitting element 14' and a second circuit board C2' electrically connected to an image sensor 122' are separated from each other and are partially accommodated in the first channel 151' and the second channel 152' of the auxiliary element 15' respectively. Furthermore, in this embodiment, the endoscope device 1' further includes an additional heat dissipation element H', which is disposed between the first circuit board C1' and the second circuit board C2' to improve the heat dissipation efficiency, wherein the additional heat dissipation element H' may be a planar plate structure. Moreover, in this embodiment, the retaining member 17' includes two retaining portions 171' and is integrally connected to the auxiliary member 15', and the heat dissipation pipe 18' is sleeved outside the auxiliary member 15'. In addition to the above differences, the endoscope device 1' of this embodiment does not include heat dissipation pins and heat dissipation glue.
