Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, and in particular to an ultra-thin electronic mammary duct endoscope. Background Technology

[0002] Endoscopic breast cancer (DBC) is an important tool for early screening and diagnosis of breast diseases, playing an irreplaceable role, especially in the detection of small lesions within the ducts (such as intraductal papilloma and carcinoma in situ). Early detection of these lesions can significantly improve treatment outcomes and patient prognosis. However, current technologies have significant limitations in practical applications, restricting the full realization of their clinical value.

[0003] Currently, the widely used duct endoscopy in clinical practice is mainly based on non-electronic fiber optic imaging technology. It relies on fiber bundles to transmit optical images, but due to the limitations of fiber filament diameter and arrangement density, the imaging resolution is generally low, making it difficult to clearly present the fine structure of the inner wall of the mammary duct (such as micro-protrusions, erosions or vascular morphology), which can easily lead to the missed diagnosis of early lesions.

[0004] The outer diameter of existing mammary duct endoscopes is mostly designed to be around 3mm, while the natural diameter of the human mammary duct is usually less than 2mm (especially in the undilated state). This makes it difficult for the instrument to penetrate into the distal branches. This contradiction forces clinical operations to rely on physical dilation or high-pressure irrigation to forcibly dilate the duct, which not only increases the patient's pain and risk of complications, but may also cause false positive image interference due to mechanical stimulation, making it impossible to effectively observe some lesions. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide an ultra-fine electronic breast duct endoscope to solve the technical problem that the current endoscopes have low pixel count and large outer diameter, making it difficult for the instrument to penetrate into the distal branch.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] An ultra-thin electronic breast duct endoscope includes an endoscope module, a steel tube, and a cable. The access end of the endoscope module is welded to the core end of the cable, and the cable passes through the inside of the steel tube. The outer diameter of the endoscope module is 1 mm.

[0009] The endoscope module includes a shape memory metal sleeve. Inside the shape memory metal sleeve, at one end away from the steel tube, is a wafer of an integrated circuit micro image sensor acquisition chip. A micro optical lens is fixed to the photosensitive end of the wafer of the integrated circuit micro image sensor acquisition chip. Inside the shape memory metal sleeve, at the end of the wafer of the integrated circuit micro image sensor acquisition chip closer to the steel tube, is a wafer of an integrated circuit micro LED chip. LED chip bodies are installed on all four sides of the wafer of the integrated circuit micro LED chip near the end face of the wafer of the integrated circuit micro image sensor acquisition chip.

[0010] As an improved technical solution, a cavity is formed between the inside of the memory metal sleeve, the wafer of the integrated circuit micro LED lamp bead chip, the LED lamp bead body, the wafer of the integrated circuit micro image sensor acquisition chip, and the micro optical lens. The cavity is filled with UV glue and solidified to form a UV glue block, and the outer end face of the memory metal sleeve, the micro optical lens, and the UV glue block is on the same end face.

[0011] As an improved technical solution, the cable includes an outer sheath, and the inner cavity of the outer sheath is provided with three coaxial conductors, two LED power lines and a ground wire.

[0012] As an improved technical solution, a PET wrapping tape is fixedly provided on the inner wall surface of the outer cover, and a first winding layer is fixedly provided on the inner wall surface of the PET wrapping tape, with the ground wire, coaxial wire and LED power line all located in the inner hole of the first winding layer.

[0013] As an improved technical solution, the coaxial wire includes a conductor, and the outer wall of the conductor is covered with an insulating layer.

[0014] As an improved technical solution, a second winding layer is fixed to the outer wall surface of the insulating layer, and both the second winding layer and the first winding layer are aluminum foil.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] In this invention, the outer diameter of the endoscope module is 1mm, which is smaller than the diameter of the natural cavity of the human breast. This makes it easier for the endoscope module to enter the human cavity directly and smoothly. On the one hand, it ensures that the endoscope module can reach the distal branch. On the other hand, it allows the endoscope module to enter without the need for physical expansion of the cavity, reducing harm to the patient and avoiding false positive image interference that would prevent some lesions from being effectively observed, thus ensuring the observation effect.

[0017] This invention uses a miniature optical lens for imaging in the endoscope module, replacing the traditional fiber optic lens with an electronic camera. This results in higher pixel density, which facilitates the clear presentation of the fine structure of the internal mucosa, enabling the early detection of lesions. Furthermore, it avoids the problems of fiber breakage and light decay that easily occur after long-term use of fiber optic lenses. On the one hand, it improves image quality, and on the other hand, it reduces the maintenance costs in the later stages.

[0018] 3. In this utility model, the second winding layer is wound on the insulation layer, which helps to reduce the attenuation of the conductor signal. The first winding layer is wound on the outside of the three coaxial conductors to further reduce the signal attenuation. It effectively reduces the signal attenuation and has a good shielding effect. It can ensure that the video signal transmission cable has no significant loss over a length of 1 meter, so that the image signal can be transmitted stably over a longer distance.

[0030] like Figures 1 to 4 As shown in the figure, this embodiment provides an ultra-thin electronic breast duct endoscope. This ultra-thin electronic breast duct endoscope includes an endoscope module 1, a steel tube 2, and a cable 3. The access end of the endoscope module 1 is welded to the core end of the cable 3, and the cable 3 passes through the inside of the steel tube 2. The outer diameter of the endoscope module 1 is 1mm. The outer diameter of the endoscope module 1 is 1mm, which is smaller than the diameter of the natural cavity of the human breast. This makes it easier for the endoscope module 1 to enter the human cavity directly and smoothly. On the one hand, it ensures that the endoscope module 1 can reach the distal branch. On the other hand, it can enter the endoscope module 1 without physical expansion of the cavity, reducing harm to the patient and avoiding false positive image interference that would prevent some lesions from being effectively observed, thus ensuring the observation effect.

[0031] Endoscope module 1 includes a shape memory metal sleeve 11, which is a specially made high-precision elastic shape memory metal sleeve. Inside the shape memory metal sleeve 11, at one end away from the steel tube 2, is a bare wafer 14 of an integrated circuit micro-image sensor acquisition chip. The bare wafer 14 represents the finished product state of the integrated circuit before packaging. The chip pads (diepads) at the bottom of the bare wafer 14 are metal areas on the integrated circuit chip used to connect the chip to a base or other devices, and are precision soldered manually. Connected to the video signal line of cable 3, UV glue is applied to strengthen its stability. A miniature optical lens 15 is fixed to the photosensitive end of the wafer die 14 of the integrated circuit miniature image sensor acquisition chip, and micro-focusing and focus setting are performed. The endoscope module 1 uses the miniature optical lens 15 for imaging. The electronic camera replaces the traditional fiber optic lens, which has higher pixel density, which is conducive to clearly presenting the fine structure of the internal mucosa and facilitating the early detection of lesions. In addition, it avoids the problems of fiber breakage and light decay that are prone to occur after long-term use of fiber optic lenses. On the one hand, it improves the image quality, and on the other hand, it reduces the maintenance cost. The miniature optical lens 15 has 160,000 pixels and a resolution of 400*400. The bare wafer die of the CMOS sensor is manually soldered onto the cable under a microscope. Inside the memory metal sleeve 11, at the end of the bare wafer die 14 of the integrated circuit miniature image sensor acquisition chip near the steel tube 2, is mounted the bare wafer die 12 of the integrated circuit miniature LED chip. The bare wafer die 12 of the integrated circuit miniature LED chip represents the finished product state of the integrated circuit before packaging. The bare wafer die 12 of the integrated circuit miniature LED chip is close to the integrated circuit miniature image sensor. LED lamp bodies 13 are installed on all four sides of one end face of the wafer die 14 of the acquisition chip. The wafer die 14 of the integrated circuit micro image sensor acquisition chip is located between the four LED lamp bodies 13. The LED lamp bodies 13 are cold light source LED white light with a color temperature of 6500K, which provides supplementary light for the camera module. In the dark internal environment, lesions and location can be clearly observed. The wafer die 12 of the integrated circuit micro LED lamp chip and the four LED lamp bodies 13 work together to provide supplementary light for the micro optical lens 15, thereby improving the clarity of the micro optical lens 15 when shooting.

[0032] like Figures 1 to 2As shown in the figure, in this embodiment, a cavity is formed between the inside of the memory metal sleeve 11, the wafer 12 of the integrated circuit micro LED chip, the LED body 13, the wafer 14 of the integrated circuit micro image sensor chip, and the micro optical lens 15. The cavity is filled with UV glue and solidified to form a UV glue block 16. The UV glue block 16 is circular, with a rectangular cavity in the middle for the micro optical lens 15 to pass through, and square cavities on the four sides for the LED body 13 to pass through. The outer end faces of the memory metal sleeve 11, the micro optical lens 15, and the UV glue block 16 are on the same end face. The UV glue block 16 is used to fill the cavity formed between the same end faces of the memory metal sleeve 11, the wafer 12 of the integrated circuit micro LED chip, the LED body 13, and the micro optical lens 15, ensuring the smoothness of the front end of the memory metal sleeve 11.

[0033] like Figure 3 As shown, in this embodiment, the cable 3 includes an outer sheath 31. The inner cavity of the outer sheath 31 is provided with three coaxial wires 35, two LED power lines 36 and a ground wire 34. The chip pads at the bottom of the wafer bare die 12 of the integrated circuit micro LED lamp bead chip are manually and precisely soldered to the two LED power lines 36 on the cable 3, and UV glue is applied to fix them to enhance their firmness.

[0034] like Figures 1 to 3 As shown in the figure, in this embodiment, a PET wrapping tape 32 is fixedly provided on the inner wall surface of the outer cover 31, and a winding layer 33 is fixedly provided on the inner wall surface of the PET wrapping tape 32. The ground wire 34, the coaxial wire 35 and the LED power line 36 are all located in the inner hole of the winding layer 33.

[0035] like Figure 4 As shown, in this embodiment, the coaxial wire 35 includes a conductor 353, and the outer wall of the conductor 353 is covered with an insulating layer 352.

[0036] like Figures 3 to 4 As shown in the figure, in this embodiment, a second winding layer 351 is fixed on the outer wall of the insulating layer 352. Both the second winding layer 351 and the first winding layer 33 are aluminum foil. The second winding layer 351 is wound on the insulating layer 352, which helps to reduce the signal attenuation of the conductor 353. The first winding layer 33 is wound on the outside of the three coaxial conductors 35 to further reduce the signal attenuation. This effectively reduces the signal attenuation and provides good shielding. It can ensure that the 3-meter-long video signal transmission cable has no significant loss, so that the image signal can be transmitted stably over a longer distance.

[0037] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
