[0037] Endoscopic camera systems are currently widely used to examine a certain organ part in the human body. When doctors perform surgeries, they need to hold the outer shell of the endoscopic camera. Blood and water residues as well as smoke particles generated during the surgery are likely to remain on the endoscope. Therefore, the endoscopic camera needs to be sterilized before and after each use. Existing endoscopic cameras include a handle and a lens module. An optical imaging module is provided inside the handle, and the optical imaging module and the handle are usually assembled by a threaded connection method. The head of the screw is exposed outside, making it difficult to sterilize the head of the screw, resulting in poor overall sterilization effect.

[0038] The present utility model proposes an endoscopic camera and an endoscopic camera system, aiming to at least solve the problem that the head of the screw is exposed outside in the related art, making it difficult to sterilize the head of the screw and resulting in poor overall sterilization effect.

[0039] Please refer to Figure 1 and Figure 2, in an embodiment of the present utility model, an endoscope camera 100 includes a handle housing 1, an optical imaging module 2, a cover plate 4, and a lens module 5. The handle housing 1 has a receiving cavity 11 with one end open. The optical imaging module 2 is fixedly installed in the receiving cavity 11 through a first fixing component 3. The first fixing component 3 is located in the receiving cavity 11. The cover plate 4 covers the opening of the receiving cavity 11. A lens screw hole 41 is provided on the cover plate 4. The lens module 5 is threadedly connected to the lens screw hole 41, and the side of the lens module 5 facing the cover plate 4 covers the lens screw hole 41.

[0040] In the technical solution of the present utility model, the handle housing 1 has a receiving cavity 11 with one end open. The optical imaging module 2 is fixedly installed in the receiving cavity 11 through a first fixing component 3. The first fixing component 3 is located in the receiving cavity 11. The cover plate 4 covers the opening of the receiving cavity 11. In this way, the optical imaging module 2 is installed in the receiving cavity 11 through the first fixing component 3 located in the receiving cavity 11, and then the receiving cavity 11 is covered by the cover plate 4, so that the first fixing component 3 for fixing the optical imaging module 2 is not exposed outside, and the surface of the overall structure is flatter, which is convenient for subsequent sterilization.

[0041] There are various methods to fixedly install the optical imaging module 2 in the receiving cavity 11. For example, it can be fixed by clamping the optical imaging module 2 with the side wall of the receiving cavity 11, or it can be inserted or glued, etc. In the embodiment of the present utility model, the first fixing component 3 includes a first threaded hole 31 provided on the side wall of the receiving cavity 11, a first through hole 32 provided on the optical imaging module 2, and a first screw 33. The first screw 33 passes through the first through hole 32 and is threadedly connected to the first threaded hole 31. In this way, after the optical imaging module 2 is placed in the receiving cavity 11, the first screw 33 passes through the first through hole 32 and is tightened in cooperation with the first threaded hole 31 to fix the optical imaging module 2. And the first screw 33, the first through hole 32, and the first threaded hole 31 are located inside the receiving cavity 11. After being covered by the cover plate 4, they are not exposed to the outside, keeping the surface of the overall endoscope camera 100 flat, which is convenient for subsequent sterilization.

[0042] It can be understood that the lens screw hole 41 for connecting the lens module 5 needs a certain length. In order to minimize the overall weight as much as possible, the cover plate 4 is usually set very thin and difficult to meet the installation requirements of the lens module 5. Therefore, the side wall of the lens screw hole 41 usually protrudes from the cover plate 4. In the embodiment of the present utility model, please refer to Figure 2, the side wall of the lens screw hole 41 protrudes towards the direction close to the optical imaging module 2 and extends into the accommodation cavity 11; with such a setting, the side wall of the lens screw hole 41 protrudes from the cover plate 4 into the accommodation cavity 11, which can meet the length requirement of the lens screw hole 41, and the overall size will not be too large. Compared with the side wall of the lens screw hole 41 protruding towards the side away from the accommodation cavity 11, the overall size is smaller.

[0043] In order to be able to fix the cover plate 4 and the optical imaging module 2, in an embodiment of the present invention, the endoscope camera 100 further includes a second fixing component 6. The second fixing component 6 includes a fixing part and a fixing and cooperating part respectively provided on the cover plate 4 and the optical imaging module 2. The fixing part and the fixing and cooperating part can cooperate to fix the cover plate 4 and the optical imaging module 2.

[0044] There are various forms of the fixing part and the fixing and cooperating part. For example, they can be connected by snap connection, screw connection or magnetic attraction connection, etc. After the fixed installation is completed, the gap between the cover plate 4 and the handle housing 1 is usually filled with glue or a practical sealing ring to reduce the possibility of blood and smoke particles entering during use. In an embodiment of the present invention, please refer to Figure 3 , the second fixing component 6 includes a second threaded hole 61 provided on the optical imaging module 2 and a second screw 62 provided on the cover plate 4. The second screw 62 is threadedly connected to the second threaded hole 61; one of the second screw 62 and the second threaded hole 61 constitutes the fixing part, and the other constitutes the cooperating part; a second through hole 63 adapted to the second screw 62 is provided on the cover plate 4, and the side of the lens module 5 facing the cover plate 4 covers the second through hole 63. When fixing, after the second screw 62 passes through the second through hole 63, it is tightened in cooperation with the second threaded hole 61 to fix the cover plate 4 and the optical imaging module 2. And after the lens module 5 is fixed by cooperating with the lens screw hole 41, it can cover the second through hole 63, that is, cover the head of the second screw 62, so as to avoid the residue of blood and smoke particles and facilitate subsequent sterilization treatment.

[0045] It can be understood that the side of the cover plate 4 can be directly pressed by the head of the second screw 62. The setting of the second screw 62 plays a positioning role for the second screw 62 and makes the fixing effect of the second screw 62 on the cover plate 4 better.

[0046] After the endoscope camera 100 is installed, the lens module 5 is not completely fixed. That is, the lens module 5 usually needs to be disassembled to replace different ones. That is, there is a certain gap between one side of the lens module 5 and the cover plate 4. Although the gap is very small, there is still a possibility of blood and smoke particles entering. To reduce this possibility, in the embodiment of the present invention, the second through hole 63 is provided in the lens screw hole 41. With this setting, when the end of the threaded head of the lens module 5 covers the second through hole 63, when blood and smoke particles need to remain on the head of the second screw 62, they need to cross the lens module 5 and the lens screw hole 41, which greatly increases the difficulty and facilitates subsequent sterilization.

[0047] In order to make the installation of the cover plate 4 more convenient, in the embodiment of the present invention, the endoscope camera 100 further includes a positioning component. The positioning component includes a positioning portion and a positioning and cooperating portion separately provided on the cover plate 4 and the optical imaging module 2. The positioning portion and the positioning and cooperating portion can cooperate to position the cover plate 4 and the optical imaging module 2.

[0048] There are various forms of cooperation between the positioning portion and the positioning and cooperating portion. For example, it can be magnetic attraction positioning cooperation, or the cooperation mode of a plug and a socket. In the embodiment of the present invention, please refer to Figure 3 , one of the positioning portion and the positioning and cooperating portion is set as a positioning convex portion, and the other is set as a positioning concave portion.

[0049] There are various setting positions for the positioning convex portion and the positioning concave portion. In the embodiment of the present invention, the side wall of the lens screw hole 41 protrudes towards the direction close to the optical imaging module 2; a groove 21 adapted to the side wall of the lens screw hole 41 is provided on the optical imaging module 2; the side wall of the lens screw hole 41 constitutes the positioning convex portion, and the groove 21 constitutes the positioning concave portion. As can be seen from the above, the length of the lens screw hole 41 needs to meet the requirements of the lens module 5, and the cover plate 4 needs to be as thin as possible. Therefore, the side wall of the lens screw hole 41 protrudes from the cover plate 4. The side wall of the lens screw hole 41 constitutes the positioning convex portion, which can play a positioning role and can save the cost of setting a positioning convex portion in the form of a positioning post or the like.

[0050] The present invention also proposes an endoscope imaging system. The endoscope imaging system includes an endoscope camera 100. The specific structure of the endoscope camera 100 refers to the above embodiment. Since this endoscope imaging system adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here.

[0051] In the technical solution of the present utility model, the handle housing 1 has a receiving cavity 11 with one end open, the optical imaging module 2 is fixedly installed in the receiving cavity 11 through a first fixing component 3, the first fixing component 3 is located in the receiving cavity 11, and the cover plate 4 covers the opening of the receiving cavity 11; thus, the optical imaging module 2 is installed in the receiving cavity 11 through the first fixing component 3 located in the receiving cavity 11, and then the receiving cavity 11 is covered by the cover plate 4, so that the first fixing component 3 for fixing the optical imaging module 2 is not exposed outside, and the surface of the overall structure is smoother, which is convenient for subsequent sterilization.

[0052] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
