As shown in fig. 1 and 2, the present invention provides an electronic endoscope 100, wherein the electronic endoscope 100 may be a bendable structure or an inflexible structure. As shown in fig. 3 and 4, when the electronic endoscope 100 is a bendable structure, the electronic endoscope 100 may include an image capturing unit 12, a joint assembly 13 connected to the image capturing unit 12, an outer heat conducting flexible tube 162 covering the joint assembly 13 and connected to the image capturing unit 12, and a driving mechanism (not shown) connected to the joint assembly 13.

Further, as shown in fig. 4, the image acquiring portion 12 includes a housing 1, a light source assembly 3 disposed in the housing 1, a PCB 6, a connecting wire 17 connected to the PCB 6, and a connecting portion 11 disposed at one end of the housing 1 far from the light source assembly 3 and connected to the joint assembly 13. The driving mechanism includes a driving portion 14 and a driving wire 18 having one end connected to the driving portion 14 and the other end connected to the joint assembly 13. Wherein a first end of the connecting wire 17 is connected with the PCB 6, a second end of the connecting wire 17 is located in the driving part 14, and a portion between the first end and the second end of the connecting wire 17 is located in the joint component 13.

In the embodiment, the driving part 14 drives the joint assembly 13 to bend so as to drive the image acquiring part 12 to move. In one embodiment, the outer heat conductive flexible pipe 162 may be connected to the housing 1, and in another embodiment, the outer heat conductive flexible pipe 162 may be connected to the connection part 11.

It is understood that the electronic endoscope 100 is suitable for single-hole surgery when it is bendable; when the electronic endoscope 100 is not bendable, the electronic endoscope is suitable for multi-hole operation. Of course, the possibility that the bendable electronic endoscope 100 may also be selected for multi-aperture surgery is not excluded. The structure of the electronic endoscope 100 can be set reasonably according to actual needs.

As shown in fig. 1, in an embodiment, the image capturing portion 12 further includes a lens mount 2 disposed in the housing 1 and used for mounting the light source assembly 3, a lens cover 4 fastened to the lens mount 2 and used for accommodating the light source assembly 3, an image sensor 5 fixedly disposed in the lens mount 2 and fixedly connected to the PCB 6 and close to one side of the light source assembly 3, a shielding cover 7 fastened to the lens mount 2 at a side away from the lens cover 4, and an insulating cover 8 covering the lens mount 2 and the shielding cover 7.

The housing 1 has a hollow cylindrical structure, but may have other reasonable shapes in other embodiments. The material of the housing 1 may be stainless steel or the like. It is understood that when the housing 1 is a hollow cylindrical structure, the lens cover 4, the lens holder 2, the shielding cover 7, the insulating cover 8, etc. may be adaptive cylindrical structures. When the electronic endoscope 100 is specifically installed, the light source assembly 3, the image sensor 5 and the PCB 6 may be fixed on the lens mount 2 to form a first module (not shown in the figure), then the lens cover 4 is fastened with the first module to form a second module (not shown in the figure), then the shielding cover 7 is fastened with the second module to form a third module (not shown in the figure), and finally the housing 1 is fastened with the third module to form the electronic endoscope 100.

As shown in fig. 6 and 7, the lens holder 2 includes a holder body 21, a heat-conducting boss 22 convexly disposed on the holder body 21, a first mounting hole 23 disposed on the holder body 21, and a mounting groove 24 concavely disposed on the holder body 21. Specifically, the mounting groove 24 is formed by recessing the side of the base body 21 away from the heat conducting boss 22 in a direction toward the heat conducting boss 22. The position of the mounting groove 24 corresponds to the position of the first mounting hole 23. That is, the mounting groove 24 communicates with the first mounting hole 23. As shown in fig. 8, the light source assembly 3 includes a light source 32 disposed on the seat 21 and a lens 33 installed in the first installation hole 23.

Further, the image sensor 5 includes a first image sensor (not shown) and a second image sensor (not shown), and the mounting groove 24 includes a first mounting groove (not shown) for receiving the first image sensor and a second mounting groove for receiving the second image sensor. Correspondingly, the number of the first mounting holes 23 includes two, and the electronic endoscope 100 further includes a first lens and a second lens corresponding to the first image sensor and the second image sensor, respectively, and the first lens and the second lens are configured to be mounted in the two first mounting holes 23, respectively. When the first image sensor and the second image sensor are respectively installed in the first installation groove and the second installation groove, the distance between the first lens and the first image sensor is equal to the distance between the second lens and the second image sensor.

In the embodiment, when the image sensor 5 is installed, the two image sensors 5 are fixed on the PCB 6, and then the two image sensors 5 are installed in the installation groove 24, so that the installation of the image sensors 5 is facilitated, and the inconsistency of the installation positions between the different image sensors 5 can be prevented, thereby avoiding the inconsistency of the images received by the different image sensors 5, and further improving the safety of a doctor in the process of using the electronic endoscope 100 to perform an operation.

Further, referring to fig. 6, the base 21 has a first side 211 and a second side 212 opposite to each other. Specifically, when the light source 32 is used as a reference, the first side surface 211 is a side close to the light source 32, and the second side surface 212 is a side far from the light source 32; when the shield can 7 is used as a reference, the first side surface 211 is a side away from the shield can 7, and the second side surface 212 is a side close to the shield can 7. In one embodiment, the first side surface 211 is connected to the heat-conducting boss 22, and the second side surface 212 is disposed opposite to the first side surface 211 on a side away from the heat-conducting boss 22. The first mounting hole 23 penetrates the first side surface 211 and the second side surface 212. The mounting groove 24 is concavely formed from the second side surface 212 to a direction close to the first side surface 211 at a position of the seat body 21 corresponding to the first mounting hole 23. The mounting groove 24 is used for mounting the image sensor 5.

Further, the light source 32 may be disposed on the heat conducting boss 22, and the heat generated by the light source 32 is conducted to the end of the electronic endoscope 100 away from the light source assembly 3 through the base body 21 by the heat conducting boss 22. In this way, good heat dissipation can be provided for the light source 32 of the electronic endoscope 100, thereby reducing the problem of light attenuation.

It should be understood that the present invention is not limited to the specific number of the lenses 33, and may be 2 or more. Of course, in other embodiments, there may be only 1 of the lenses 33. Correspondingly, the number of the light sources 32 and the image sensors 5 corresponds to the number of the lenses 33. Of course, in other embodiments, there may be only one image sensor 5. However, compared with the scheme with only one image sensor 5, the present embodiment can avoid the interference to the image, thereby improving the quality of the image acquired by the electronic endoscope 100.

Further, as shown in fig. 7, the base 21 extends from the edge of the second side 212 to a direction away from the first side 211 to form a first extending portion 25, and the first extending portion 25 and the second side 212 enclose to form an accommodating space 26. As shown in fig. 1, 10 and 11, the PCB board 6 has an abutting surface 60 adapted to the first extending portion 25, and when the PCB board 6 enters the accommodating space 26, the first extending portion 25 interferes with the abutting surface 60. In this way, when the PCB 6 enters the accommodating space 26 through the guiding action of the first extending portion 25, the PCB 6 and the image sensor 5 can be precisely positioned and mounted in the mounting groove 24, so as to further improve the mounting precision of different image sensors 5 and PCBs 6, and further improve the quality of images acquired by the electronic endoscope 100.

As shown in fig. 7, the diameter of the first mounting hole 23 may be the same as the width of the mounting groove 24, or the width of the mounting groove 24 may be larger than the diameter of the first mounting hole 23. Thus, the fixing glue can be prevented from leaking to the lens 33 when the module is mounted. After the image sensor 5 is fixedly connected to the PCB 6, and the image sensor 5 is fixed to the mounting groove 24, the accommodating space 26 and other accommodating spaces away from the lens cover 4 may be filled with a heat conducting adhesive, so as to further increase the heat conducting effect.

In an embodiment, as shown in fig. 6, the heat conducting boss 22 includes a substrate 221 connected to the base body 21 of the lens holder 2 and a fixing groove 222 recessed on the substrate 221. The substrate 221 is recessed from a side away from the lens holder 2 to a direction close to the lens holder 2 to form the fixing groove 222, and the fixing groove 222 is used for mounting and fixing the light source 32.
