The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0034] The utility model provides a head end component 1, which can be applied to an ultra-thin endoscope 100. At least part of the head end component 1 is inserted into a patient's body to obtain image information inside the patient's body, so as to facilitate diagnosis and treatment of the affected area.

[0035] Specifically, see Figure 1 , Figure 3 and Figure 4 The head end assembly 1 includes an insertion portion 11, an image acquisition structure 12 and an illumination structure 13. The insertion portion 11 is arranged in a narrow and long shape and is provided with an inner cavity extending along its length direction; the image acquisition structure 12 is arranged at the front end of the inner cavity and at least part of it can be exposed from the front end of the insertion portion 11; the illumination structure 13 is arranged at the front end of the inner cavity and is arranged in close contact with the image acquisition structure 12, and the detection field of view of the image acquisition structure 12 and the illumination field of view of the illumination structure 13 are both arranged toward the outside of the front end of the insertion portion 11.

[0036] In the technical solution provided by the utility model, the interior of the insertion part 11 is hollow to form an inner cavity, and the inner cavity can be used for the image acquisition structure 12, the lighting structure 13 and the integrated cable 15 to pass through, so as to protect the image acquisition structure 12, the lighting structure 13 and the integrated cable 15; the image acquisition structure 12 can be used to obtain image information in the patient's body when the insertion part 11 intervenes in the patient's body, and the lighting structure 13 can be used to provide lighting light for image acquisition in the image acquisition structure 12 to ensure that the acquired image information is clearer; moreover, the lighting structure 13 is arranged in close contact with the image acquisition structure 12, so that the structure between the lighting structure 13 and the image acquisition structure 12 is more compact and occupies less space, so that the outer diameter of the insertion part 11 can be set smaller, which is conducive to the miniaturization of the head end assembly 1, thereby reducing the damage caused to the patient when the insertion part 11 intervenes in the patient's body, so as to reduce the discomfort of the patient during the treatment process.

[0037] Prioritize, combine Figures 1 to 3 As shown, the insertion portion 11 is generally cylindrical, and the axial direction of the insertion portion 11 is the length direction of the insertion portion 11. It should be noted that when the head end assembly 1 is in normal use, the end of the insertion portion 11 close to the patient is the front end, and the end away from the patient is the rear end. The description of the orientation in the present utility model can be referred to as such unless otherwise specified.

[0038] Furthermore, the material of the insertion part 11 is metal. And preferably, the insertion part 11 is a whole stainless steel tube, which has better corrosion resistance, is easy to clean, and is easier to insert into the patient's body. Further preferably, the diameter of the insertion part 11 can be 1.5 mm, and the length of the insertion part 11 can be 60, 90, or 120 mm, to ensure that the insertion part 11 has sufficient strength and rigidity, and a small diameter will cause less harm to the patient, and is also convenient for disinfection and cleaning.

[0039] The image acquisition structure 12 is mainly used to collect image information in the patient's body after the insertion portion 11 is inserted into the patient's body, so as to facilitate medical staff to observe and better realize the diagnosis and treatment of the affected part. Figures 3 to 5 As shown, the image acquisition structure 12 includes a camera element 121, which is located at the front end of the inner cavity and at least partially protrudes from the front end of the insertion part 11, so that when the camera element 121 is performing image acquisition, the detection field of view of the camera element 121 will not be blocked by the insertion part 11, so that the detection field of view is wider, the detection range is wider, and the acquired image information is clearer and more comprehensive.

[0040] The imaging element 121 may be a camera, a CMOS (Complementary Metal Oxide Semiconductor), or a CCD (Charge-coupled Device, also known as image controller). Of course, the imaging element 121 may also be other image control devices suitable for use in the ultra-thin endoscope 100, without limitation.

[0041] Furthermore, the imaging element 121 is roughly rectangular, and the length direction of the imaging element 121 extends along the insertion portion 11 and the length direction. The front end surface of the imaging element 121 is roughly square and is arranged toward the front end outside of the inner cavity.

[0042] The lighting structure 13 is mainly used to illuminate the detection field of the image acquisition structure 12 after the insertion portion 11 is inserted into the patient's body, so as to facilitate the image acquisition structure 12 to obtain clearer image information. Figure 3 and Figure 4 As shown, the lighting structure 13 includes an illumination lamp 131, which is also arranged in the inner cavity and is located on one side of the imaging element 121 to fit the imaging element 121, so that the structure between the illumination lamp 131 and the imaging element 121 is more compact and occupies less space, so that the outer diameter of the insertion part 11 can be set smaller, so that when the insertion part 11 intervenes in the patient's body, the damage to the patient is less, which is conducive to improving the comfort of the patient's treatment.

[0043] Furthermore, the front end surface of the illuminating lamp 131 is located behind the front end surface of the imaging element 121, that is, the light emitting surface of the illuminating lamp 131 is located behind the detection field of view of the imaging element 121, so that the light emitted by the illuminating lamp 131 will not enter the edge of the imaging element 121, avoiding the formation of a light spot at the edge of the imaging element 121, avoiding overexposure around the collected image, and making the image collected by the head end assembly 1 clearer. Preferably, the distance between the front end surface of the illuminating lamp 131 and the front end surface of the insertion part 11 is 0.2 mm, so that the light of the illuminating lamp 131 can be fully emitted without affecting the shooting effect of the imaging element 121.

[0044] Furthermore, preferably, Figure 4As shown in , two illuminators 131 are provided, and the two illuminators 131 are symmetrically arranged on both sides of the imaging element 121 to fit the outer side surface of the imaging element 121. For example, when the width direction and the height direction of the imaging element 121 are arranged along the up-down direction and the left-right direction respectively, the two illuminators 131 can be arranged on the left and right sides of the imaging element 121 respectively, or the two illuminators 131 can be arranged on the upper and lower sides of the imaging element 121 respectively, so that the illuminators 131 can provide sufficient illumination without affecting the detection field of view of the imaging element 121. Moreover, the two illuminators 131 can fit the outer side wall of the imaging element 121 more closely, so that the structure is more compact. Specifically, the lighting lamp 131 can be an LED lamp with a small size. The lighting lamp 131 can be glued to the camera element 121 by glue. During assembly, the two lighting lamps 131 can be first glued to the camera element 121, and then the whole can be installed in the inner cavity of the insertion part 11. The assembly of the camera element 121 and the lighting lamp 131 can be performed outside the insertion part 11, which makes assembly more convenient and the assembly efficiency will be higher.

[0045] In addition, combined Figure 3 and Figure 4 As shown, the head end assembly 1 also includes a heat sink 14 which is sleeved on the inner side of the inner cavity. The heat sink 14 is arranged around the outer peripheral side of the imaging element 121 and close to the illumination lamp 131. The heat sink 14 is thermally conductive and can conduct the heat on the imaging element 121 and the illumination lamp 131 to the insertion portion 11, thereby quickly dissipating the heat accumulated on the imaging element 121 and the illumination lamp 131 to avoid excessive heat on the imaging element 121 and the illumination lamp 131, thereby preventing discomfort or injury to the patient.

[0046] The heat sink 14 is roughly cylindrical, and the outer peripheral side of the heat sink 14 is formed to match the shape of the inner cavity so as to be fixed to the inner side of the inner cavity. A through hole is provided on the heat sink 14 along the front-to-back direction, and the through hole is connected to the inner cavity. The camera element 121 and the lighting lamp 131 are both provided at the front end of the through hole. Moreover, the image acquisition structure 12 also includes an integrated cable 15, which is electrically connected to the rear end of the camera element 121 and can extend from the rear end of the through hole to penetrate into the inner cavity. The integrated cable 15 can transmit the image information collected by the camera element 121, and can transmit electrical energy to the lighting lamp 131.

[0047] The front end surface of the heat sink 14 is flush with the front end surface of the inserting portion 11, so that during assembly, the illuminating lamp 131 should be located inside the through hole of the heat sink 14. Figure 6As shown in , the distance X between the front end surface of the illuminating lamp 131 and the front end surface of the heat sink 14 is 0.2 mm. The heat sink 14, the imaging element 121 and the illuminating lamp 131 are assembled outside the insertion portion 11, making the assembly more convenient and ensuring the assembly accuracy.

[0048] Moreover, the shape of the front end of the heat sink 14 matches the shape of the front end of the imaging element 121, and the two sides of the heat sink 14 can be clamped and fixed to the two opposite sides of the imaging element 121, so that the imaging element 121 is more stable. The heat sink 14 is provided with a avoiding notch at the position corresponding to the lighting lamp 131 to ensure that the lighting area of ​​the lighting lamp 131 is not blocked.

[0049] Furthermore, in the direction from front to back, the through hole is tapered at the transition point between the corresponding imaging element 121 and the integrated cable 15. On the one hand, it can limit the rear end of the imaging element 121, and on the other hand, it makes the shape of the through hole more compatible with the shape of the integrated cable 15, thereby ensuring that the integrated cable 15 can be better passed through.

[0050] Preferably, the heat sink 14 is made of metal, which makes the heat conduction rate faster, can better avoid the temperature accumulation at the imaging element 121, and better protect the patient. The temperature at the imaging element 121 can be conducted to the entire insertion part 11 more quickly, thereby dissipating the heat.

[0051] Of course, the heat sink 14 can also be configured as a heat sink, heat sink adhesive or other structures with heat dissipation function.

[0052] The utility model also provides an ultra-thin endoscope 100, combined with Figure 1 and Figure 2 As shown, the ultra-thin endoscope 100 includes an operating part 2 and the above-mentioned head end component 1, wherein the head end component 1 is arranged at the front end of the operating part 2. When operating the ultra-thin endoscope 100, the medical staff can hold the operating part 2 and insert the head end component 1 into the patient's body to diagnose and treat the affected part.

[0053] Among them, the ultra-thin endoscope 100 also includes a transfer circuit board structure 3 arranged in the operating part 2, and a signal cable 4 with one end electrically connected to the transfer circuit board structure 3, and the other end of the signal cable 4 can extend from the rear end of the operating part 2 to be electrically connected to the display device or the operating device. The integrated cable 15 of the head end component 1 can extend from the front end of the operating part 2 into the operating part 2 and be electrically connected to the transfer circuit board structure 3. The transfer circuit board structure 3 includes a circuit board and electronic components arranged on the circuit board. The electronic components have a shielding function, thereby preventing interference signals, thereby avoiding interference with the signal during long-distance transmission. The transfer circuit board structure 3 can ensure better signal transmission quality and ensure that the received image information is more stable and reliable.

[0054] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
