[0033] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application. Figures 1 to 6 As shown in the drawings, the present application provides a precise infrared thermal imaging inspection equipment, which comprises a first thermal imaging tube 1, a second thermal imaging tube 3, an operating handle 5 and a thermal imaging assembly 16.

[0034] Specifically,

[0035] The front end of the first thermal imaging tube 1 is provided with a first horn-shaped heat shield 2, and the inner diameter of the first horn-shaped heat shield 2 gradually increases from the end closer to the first thermal imaging tube 1 to the end farther away from the first thermal imaging tube 1. The second thermal imaging tube 3 is movably sleeved outside the first thermal imaging tube 1, and the second thermal imaging tube 3 is longer than the first thermal imaging tube 1. The front end of the second thermal imaging tube 3 is provided with a second horn-shaped heat shield 4, and the second horn-shaped heat shield 4 is located outside the first horn-shaped heat shield 2. Similarly, the inner diameter of the second horn-shaped heat shield 4 gradually increases from the side closer to the second thermal imaging tube 3 to the side farther away from the second thermal imaging tube 3.

[0036] To facilitate the insertion of the first horn-shaped heat shield 2 and the second horn-shaped heat shield 4 into the body via an endoscope or intubation device, both are made of flexible materials (such as silicone). This allows them to retract as they pass through the tube into the body, enabling easy insertion via the endoscope or intubation device. Simultaneously, the inner walls of both the first horn-shaped heat shield 2 and the second horn-shaped heat shield 4 are coated with a heat-insulating coating, ensuring that thermal imaging is only formed within the area covered by either the first horn-shaped heat shield 2 or the second horn-shaped heat shield 4.

[0037] In this embodiment, in order to enable the first thermal imaging tube 1 to move back and forth inside the second thermal imaging tube 3, see [reference needed]. Figures 1 to 3 As shown, the operating handle 5 is fixed to the end of the second thermal imaging tube 3 away from the second horn-shaped heat shield 4, and a hollow clearance cavity is provided inside the operating handle 5. A first adjustment mechanism is provided on the operating handle 5, which is used to move the first thermal imaging tube 1 back and forth within the second thermal imaging tube 3. Specifically, the first adjustment mechanism includes a first adjustment slider 6 and a first connecting block. The operating handle 5 has a first sliding groove 7 extending back and forth along its length. The first adjustment slider 6 is slidably disposed within the first sliding groove 7. The first adjustment slider 6 is fixedly connected to the end of the first thermal imaging tube 1 through the first connecting block (not shown in the figure). It can be imagined that by pushing it backward... When the first adjusting slider 6 is moved, it is fixed to the first thermal imaging tube 1 via the first connecting block. When the first adjusting slider 6 moves backward, it drives the first thermal imaging tube 1 to move backward. At this time, the second horn-shaped heat shield 4 is further forward than the first horn-shaped heat shield 2. Therefore, the area covered by the second horn-shaped heat shield 4 is the detection area. When the first adjusting slider 6 moves forward, the first thermal imaging tube 1 also moves forward. At this time, the outer wall of the first horn-shaped heat shield 2 is attached to the inner wall of the second horn-shaped heat shield 4, blocking the second horn-shaped heat shield 4. Therefore, the area covered by the first horn-shaped heat shield 2 is the detection area.

[0038] Of course, in one embodiment, in order to make the larger second horn-shaped heat shield 4 to be able to enter the body more smoothly through the endoscope or introduction device, and the size of the horn opening can be controlled to more accurately heat the image of the appropriate range of lesions, see Figures 4 to 6 As shown, the inner wall of the second thermal imaging tube 3 is fixed with a contraction adjusting mechanism for opening and closing the second horn-shaped heat shield 4, and the operating handle 5 is provided with a second adjusting mechanism for controlling the contraction adjusting mechanism.

[0039] Specifically: the contraction adjusting mechanism includes a metal ring sleeve 8, a contraction metal arm 9, a connecting short shaft 10, a metal rod 11 and a spring 12, wherein the metal ring sleeve 8 is fixed to the inner wall of the second thermal imaging tube 3, and is sleeved on the outer wall of the first thermal imaging tube 1, and the metal ring sleeve 8 is provided with three hinge seats on the outer wall near one end of the second horn-shaped heat shield 4, each hinge seat is connected with a contraction metal arm 9 through a pivot, the contraction metal arm 9 can be freely opened and closed, the contraction metal arm 9 is flexible and can be bent, the inner wall of the second thermal imaging tube 3 is provided with a first guide channel extending to the side of the front end of the second horn-shaped heat shield 4, the contraction metal arm 9 is deformed along the first guide channel to the front end of the second horn-shaped heat shield 4 and is fixed by heat melting.

[0040] The connecting short shaft 10 is vertically connected with the contraction metal arm 9, one end of the metal rod 11 is provided with a U-shaped connecting part, and the connecting short shaft 10 is connected to the U-shaped connecting part through a pivot, so that the connecting short shaft 10 and the metal rod 11 are movably connected, the metal ring sleeve 8 is provided with three second guide channels along the length direction, and the three metal rods 11 pass through the metal ring sleeve 8 from the second guide channel, and the spring 12 is connected between the metal rod 11 and the connecting short shaft 10.

[0041] In addition, the second adjusting mechanism includes a second adjusting sliding block 13, a main metal wire 14 and three branch metal wires 15, wherein the operating handle 5 is provided with a second sliding groove 17 extending forward and backward, the second adjusting sliding block 13 is slidingly arranged in the second sliding groove 17 and slides forward and backward along the operating handle 5, one end of the main metal wire 14 is fixedly connected with the second adjusting sliding block 13, one end of the three branch metal wires 15 is connected with the other end of the main metal wire 14, and the other end of the three branch metal wires 15 is respectively connected with the three metal rods 11.

[0042] Thus, it can be imagined that when the second adjusting slider 13 is slid backward, the three sub-wires 15 are pulled by the main wire 14 to pull the metal rod 11, the metal rod 11 acts on the connecting short shaft 10, at this time the spring 12 is compressed, the metal rod 11 pulls the retractable metal arm 9 backward through the connecting short shaft 10, so that the flexible second horn-shaped heat shield 4 is pulled backward and shrinks to the center of the shield, so that it is easier to enter the body through the endoscope or the delivery device. Of course, after entering the body, the second adjusting slider 13 is slid forward, the spring 12 restores to the original length and drives the retractable metal arm 9 to move forward, so that the second horn-shaped heat shield 4 is opened, self-reduces during use and is closed after use.

[0043] Finally, the thermal imaging assembly 16 is fixed to the inner wall of the first thermal imaging tube 1 and is close to one end of the first horn-shaped heat shield 2, the thermal imaging assembly 16 irradiates forward through the first thermal imaging tube 1 to perform thermal imaging on the area covered by the first horn-shaped heat shield 2 or the second horn-shaped heat shield 4. It should be pointed out that the thermal imaging assembly 16 is a mature existing device, which includes pyroelectric material and a front Fresnel lens, the thermal imaging assembly 16 can be programmed to record current values and corresponding temperature values, connect an external display, display on the display screen, and accurately convert the electrical signal to form a thermal optical image on the screen.

[0044] In summary, the precise infrared thermal imaging inspection device provided by the embodiment of the present application has the following use method:

[0045] First, the second adjusting slider 13 is moved backward, and the second horn-shaped heat shield 4 is shrunk and gathered through the shrinkage adjusting mechanism;

[0046] Then, the first thermal imaging tube 1, the second thermal imaging tube 3, the first horn-shaped heat shield 2 and the second horn-shaped heat shield 4 are delivered into the body through the delivery device or the endoscope, since the first horn-shaped heat shield 2 and the second horn-shaped heat shield 4 are made of flexible material and can be shrunk when passing through the pipeline, it is very convenient to enter the human body.

[0047] After entering the human body, then the second adjusting slider 13 is moved forward, and the second horn-shaped heat shield 4 is opened through the shrinkage adjusting mechanism;

[0048] Then, the first adjusting slider 6 is moved backward, so that the first thermal imaging tube 1 moves backward, at this time, the second horn-shaped heat shield 4 is located in front of the first horn-shaped heat shield 2, the lesion is covered by the second horn-shaped heat shield 4, and the second horn-shaped heat shield 4 has the characteristic of being larger than the first horn-shaped heat shield 2, so that the thermal imaging assembly 16 can perform thermal imaging in a larger area, and the position of the suspected lesion can be found more quickly.

[0049] After discovering the suspected lesion, the first adjusting slider 6 is moved forward to move the first thermal imaging tube 1 forward, the first horn-shaped heat shield 2 blocks the second horn-shaped heat shield 4, then the first horn-shaped heat shield 2 at the front end of the first thermal imaging tube 1 covers the suspected lesion, and spotlight thermal imaging in a small area is performed, so as to clearly display the lesion position and clearly image.

[0050] Finally, after obtaining the thermal imaging picture, the first thermal imaging tube 1, the second thermal imaging tube 3, the first horn-shaped heat shield 2 and the second horn-shaped heat shield 4 are withdrawn from the human body.

[0051] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
