Description

Technical Field

[0001] The utility model relates to the technical field of endoscope image transmission modules, in particular to a high-definition transmission image module suitable for an endoscope. Background Art

[0002] The quality of the image transmitted by the endoscope directly affects the use effect of the endoscope and the accuracy of the inspection. Today's endoscopes strive to develop towards miniaturization, multi-functions, and high image quality. However, since most of the use scenarios of medical endoscopes involve electronic devices, it is easy to cause electromagnetic interference to the transmission of high-definition images of the endoscope, and the power cords of the endoscope lens and LED lighting are prone to generate static electricity when current passes through. Due to many factors, the length of existing endoscope transmission lines is often short, mostly between 300-400cm, in order to ensure the quality of the transmitted image. In order to overcome this problem, the existing technology usually sets a filtering circuit at the corresponding position to prevent electromagnetic interference from affecting endoscopic imaging. However, this filtering method not only still has the problem of static electricity, but the filtering circuit cannot completely eliminate the interference. Interference will still exist in the circuit, affecting the transmission of high-definition images of the endoscope and the final imaging quality. Utility Model Content

[0003] The purpose of the present utility model is to address the above-mentioned problems and to provide a high-definition transmission image module suitable for an endoscope. The high-definition image transmission component of the high-definition transmission image module has a built-in grounding layer and an anti-interference layer. The ground wire laid in the grounding layer can promptly conduct the static electricity generated when the current passes through. The anti-interference layer can shield the electromagnetic interference of external equipment on the high-definition image transmission line, fundamentally eliminating the interference factors, so that the high-definition image transmission line originally 300-400cm can be extended to 594cm while still ensuring the quality of the transmitted image.

The camera end of the high-definition camera 4 and the lighting end of the LED lighting lamp 5 are exposed and flush with the surface of one side of the high-definition camera assembly 1, and the bottom of the other side of the high-definition camera assembly 1 is fixedly connected to one end of the high-definition image transmission assembly 2, and the other end of the high-definition image transmission assembly 2 is fixedly connected to the endoscope plug connector 3.

[0024] As Figure 4 shown, the high-definition image transmission assembly 2 is rectangular in cross-sectional shape, and sequentially comprises a grounding layer 6, an anti-interference layer 7 and an insulating protective layer 8 from inside to outside. The grounding layer 6 is fixedly laid with ground wires and power supply wires, the anti-interference layer 7 is fixedly laid with high-definition image transmission wires, one end of the power supply wires is fixedly connected with the high-definition camera 4 and the LED illuminating lamp 5 respectively, and the other end is fixedly connected with the corresponding wiring points on the endoscope connector 3. One end of the high-definition image transmission wires is fixedly connected with the high-definition camera 4, and the other end is fixedly connected with the corresponding wiring points on the endoscope connector 3.

[0025] It should be noted that the high-definition image transmission assembly 2 is rectangular in cross-sectional shape in this embodiment, so the ground wires are arranged in the form of a flat cable in the grounding layer 6, and the power supply wires are arranged in the flat cable.

[0026] In this embodiment, the endoscope connector 3 comprises a connector top block 9 and conductive contact pads 10. The connector top block 9 is fixedly installed at the center of the endoscope connector 3, and two rows of conductive contact pads 10 are fixedly welded on the left and right sides of the connector top block 9 respectively.

[0032] Working principle and process

[0033] First, the endoscope connector 3 is used as the connection end, which is inserted into the interior of the endoscope pipeline and plugged into the data transmission connector. At this time, the connector top block 9 is engaged with the groove reserved in the endoscope pipeline, which makes it convenient for medical staff to know that the endoscope connector 3 has been plugged in place and prevents the entire high-definition transmission image module from falling out of the endoscope pipeline during operation. After the endoscope connector 3 is plugged in, the camera end face of the high-definition camera component 1 is flush with the end face of the endoscope pipeline, completing the assembly of the high-definition transmission image module; during the operation of the endoscope, the ground wire laid in the grounding layer 6 of the high-definition image transmission component 2 can timely conduct the static electricity generated when the current passes through, and the anti-interference layer 7 is made of polyethylene PE material, which can shield the electromagnetic interference of external equipment to the high-definition image transmission line, thereby fundamentally eliminating the interference factors, so that the original high-definition image transmission line of 300-400cm can not only be extended to 594cm, but also still ensure the quality of the transmitted image.
