[0040] In order to make the technical personnel in the field of the present application better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings.

[0041] With reference to Figures 1-4 The embodiment of the present application shows an endoscope imaging device, which is used in cooperation with an endoscope handheld body 2 in use,

[0042] The endoscope imaging device 1 comprises an imaging cable 11, a first interface assembly 12 and a second interface assembly 13;

[0043] The imaging cable 11 comprises opposite cable first end 111 and cable second end 112, the imaging cable 11 is arranged in the first interface assembly 12, and the cable first end 111 and the cable second end 112 are both outside the first interface assembly 12; the first interface assembly 12 is used to connect with the endoscope handheld body 2;

[0044] The imaging cable 11 comprises a cable sleeve 113, an imaging assembly 114 and a light source assembly 115, the light source assembly 115 is arranged on the outer circumferential side of the imaging assembly 114, and the imaging assembly 114 and the light source assembly 115 are arranged in the cable sleeve 113; the cable second end 112 is arranged in the second interface assembly 13, and the line ends of the imaging assembly 114 and the light source assembly 115 are integrated in the second interface assembly 13.

[0045] In this embodiment, by designing a detachable structure of the endoscope imaging device, the endoscope imaging device is separated from the endoscope hand-held body, so that only the hand-held body needs to be discarded after each use, and the endoscope imaging device can be taken out and reused, thereby significantly reducing the use cost of the endoscope.

[0046] The imaging cable 11 is used to transmit image data and light source signals. The imaging cable 11 has a certain length, which is arranged in the first interface assembly 12, which is arranged at a preset distance from the first end 111 of the cable. The preset distance can be designed according to the size of the front end structure of the endoscope hand-held body 2 for accommodating the imaging cable 11, specifically, so that when the endoscope imaging device 1 and the endoscope hand-held body 2 are installed in place, that is, the first end 111 of the imaging cable 11 is inserted into the endoscope hand-held body 2, and the first end 111 of the cable is close to the front end of the endoscope hand-held body 2, at this time, by connecting the first interface assembly 12 with the endoscope hand-held body 2, the installation of the endoscope imaging device 1 and the endoscope hand-held body 2 is achieved, and the position of the first end 111 of the cable is fixed. By reasonably setting the preset distance of the first interface assembly 12 from the first end 111 of the cable, the first end 111 of the cable can be as close as possible to the part to be examined of the patient, so as to improve the accuracy of the examination.

[0047] The imaging cable 11 includes a cable sleeve 113, an imaging assembly 114, and a light source assembly 115. The cable sleeve 113 is used to protect the imaging assembly 114 and the light source assembly 115 from damage and maintain their structural flexibility, and is arranged to wrap the imaging assembly 114 and the light source assembly 115. The material of the cable sleeve 113 should have sufficient flexibility to ensure that the endoscope imaging device 1 can be smoothly inserted into the endoscope hand-held body 2. The imaging assembly 114 is used to capture images in the body. The light source assembly 115 is used to provide necessary illumination for the imaging assembly 114.

[0049] The second interface assembly 13 is used to realize convenient connection with the external image processing terminal device 3. The second interface assembly 13 integrates the line ends of the imaging assembly 114 and the light source assembly 115, so that the signals and data of the endoscope imaging device can be transmitted through the second interface assembly 13.

[0050] The detachable design of the endoscope imaging device is realized by the above structure, so that the endoscope imaging device can be reused, and only the endoscope hand-held main body needs to be discarded, thereby significantly reducing the use cost each time. In addition, the design of the first interface assembly and the second interface assembly makes the connection and disconnection of the endoscope imaging device simple and fast, greatly improving the work efficiency of doctors.

[0052] In this embodiment, the first interface assembly 12 is designed to be movably arranged relative to the imaging cable 11, that is, the imaging cable 11 can move relative to the first interface assembly 12, and the through hole opened on the first interface assembly 12 can be slightly larger than the outer diameter of the imaging cable 11, thereby realizing the above-mentioned movable arrangement. This is to be able to fine-tune the position of the cable first end 111 of the imaging cable 11 after the imaging cable 11 is inserted into the endoscope hand-held main body 2, so that the cable first end 111 is as close as possible to the end of the endoscope hand-held main body 2, and then as close as possible to the part of the patient to be examined, thereby improving the accuracy of the examination.

[0053] The above-mentioned connecting part 1211 is arranged on the interface first end 121, which is used to realize stable mechanical connection with the endoscope hand-held main body 2. It can be understood that Figure 5 The structure of the connecting part 1211 is indicated in the frame, because the specific form of the connecting part 1211 can be diversified, for example, using pins, jacks, threads, rubber plugs, bayonets or other types of connection structures to ensure firm connection with the endoscope hand-held main body 2.

[0057] The connecting assembly 14 is made of a material with certain flexibility, such as rubber, plastic or metal braided wire, etc., to ensure certain bending ability during connection, facilitating storage and use of the endoscope imaging device. The connecting assembly 14 is arranged outside the imaging cable 11, and can also play a certain protection effect on the imaging cable 11.

[0058] In one specific embodiment, the length of the connecting assembly 14 is variable, and the length is the distance from the interface second end 122 to the interface third end 131 when the connecting assembly 14 is stretched to a flat state.

[0059] In the embodiment, the length of the connecting assembly 14 is adjusted according to the moving position of the first interface assembly 12.

[0060] The length of the connecting assembly 14 is variable, which means that it can be switched and adjusted between a shorter compact state and a longer stretched state. In the embodiment, the "length" is defined as the distance from the interface second end 122 to the interface third end 131 when the connecting assembly 14 is stretched to a flat state. The length change can be realized in various ways, for example, by using elastic materials, stretchable braided wires or elastic members, etc.

[0062] In another embodiment, the connecting assembly 14 is made of a stretchable braided wire, which is composed of a plurality of filaments. The filaments can slide relative to each other to allow the length to change. When an external force acts on the braided wire, the sliding between the filaments allows the braided wire to stretch; and when the external force is removed, the braided wire is restored to the original length through the elasticity or friction of the filaments.

One end of the second connecting sleeve 142 is connected with the third end 131 of the interface, and the other end forms a mutual sleeving structure with the first connecting sleeve 141. When the elastic member 143 is in the maximum stretching state, at least part of the first connecting sleeve 141 and the second connecting sleeve 142 are mutually sleeved, so as to ensure the integrity of the appearance of the connecting assembly 14 even when the elastic member 143 is stretched to the limit position, and to avoid the exposure of the elastic member 143 which is easy to be damaged.
