[0023] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all structures.
[0024] Figure 1 is a schematic structural diagram of a visual puncture mirror according to an embodiment of the present invention, Figure 2 is Figure 1 a schematic bottom view structure diagram of the visual puncture mirror shown in Figure 1 andFigure 2 , the visible puncture mirror includes a movable puncture needle 5, a main body tube 6 of the mirror, and a camera assembly. The movable puncture needle 5 includes a needle tip, and the movable puncture needle 5 is used for puncture. In one embodiment, the movable puncture needle 5 is used for puncturing the abdominal cavity, thus having a basic body surface puncture function. The main body tube 6 of the mirror is sleeved in the cavity of the movable puncture needle 5. The camera assembly is arranged on one side of the main body tube 6 close to the needle tip, and the camera assembly includes a first camera 8 and a second camera 9 which are separately arranged. The first camera 8 and the second camera 9 are independent of each other, and the first camera 8 and the second camera 9 are spaced apart by a certain distance.
[0025] In an embodiment of the present utility model, for a visible puncture mirror, after the movable puncture needle 5 punctures the abdominal cavity, the camera assembly arranged in the main body tube 6 of the mirror can penetrate an object inside the body. The camera assembly includes a first camera 8 and a second camera 9 which are separately arranged. The first camera 8 and the second camera 9 capture different images. The images captured by the first camera 8 and the images captured by the second camera 9 are spliced into one image. The embodiment of the present utility model utilizes a dual-camera to overlap the images to form an ultra-large viewing angle, increasing the viewing angle.
[0026] Exemplarily, referring to Figure 1 and Figure 2 , the outer diameter of the movable puncture needle 5 is 10 mm, and the puncture function can be realized. The outer diameter of the main body tube 6 of the mirror is 8 mm. The main body tube 6 of the mirror is configured with 2 cameras (the first camera 8 and the second camera 9), and the viewing angle of a single camera is 90°. By splicing the images of the 2 cameras into one image, the viewing angle can be enlarged by more than 30%, reaching a viewing angle of more than 130°, realizing a large viewing angle display.
[0027] Optionally, referring to Figure 1 and Figure 2 , the main body tube 6 of the mirror is further provided with an instrument channel 10. The instrument channel 10 penetrates through the main body tube 6 of the mirror, and the instrument channel 10 is used for passing medical instruments. Thus, medical instruments can be passed through the instrument channel 10, and in-vivo operations can be performed through the medical instruments, such as in-vivo biopsy extraction, in-vivo further puncture function, or simple surgical examination.
[0028] Optionally, referring to Figure 1 and Figure 2 , the main body tube 6 of the mirror is further provided with a common hole 7. The common hole 7 is arranged at an interval from the instrument channel 10, and the common hole 7 and the instrument channel 10 are two non-connected and independent channels. The common hole 7 is used for passing gas and / or liquid. When the common hole 7 is used for passing liquid, the functions of flushing and drainage of the puncture operation can be realized.
[0029] Optionally, referring to Figure 1 and Figure 2, the visible puncture scope further includes an air vent pipe 4 disposed on the side of the movable puncture needle 5, and the air vent pipe 4 communicates with the common hole 7. Thus, gas and / or liquid can be infused into the common hole 7 through the air vent pipe 4 to achieve the functions of flushing and drainage during the puncture operation. The air vent pipe 4 can be connected to a gas supply device or a flushing device. When the air vent pipe 4 is connected to the gas supply device, the fluid in the air vent pipe 4 and the common hole 7 is gas. When the air vent pipe 4 is connected to the flushing device, the fluid in the air vent pipe 4 and the common hole 7 is liquid.
[0030] Optionally, referring to Figure 1 and Figure 2 , at the end of the main body of the scope 6 near the needle tip, the first camera 8 and the second camera 9 are located on both sides of the line connecting the common hole 7 and the instrument channel 10. Among them, the end of the main body of the scope 6 near the needle tip is the end of the main body of the scope 6 that punctures into the body during the puncture operation. It can be understood that since the instrument channel 10 is used to pass medical devices, the diameter of the instrument channel 10 is usually large, occupying a large space in the cross-section of the main body of the scope 6. By arranging the first camera 8 and the second camera 9 on both sides of the line connecting the common hole 7 and the instrument channel 10, the space on both sides of the line connecting the common hole 7 and the instrument channel 10 can be fully utilized without reducing the diameter of the instrument channel 10.
[0031] In other embodiments, the positions and angles of the first camera 8 and the second camera 9 can also be flexibly adjusted as needed to adapt to different observation scenarios and requirements.
[0032] Exemplarily, referring to Figure 2 , at the end of the main body of the scope 6 near the needle tip, the line connecting the first camera 8 and the second camera 9 is perpendicular to the line connecting the common hole 7 and the instrument channel 10. Thus, the fields of view of the first camera 8 and the second camera 9 can be superimposed in a direction perpendicular to the line connecting the common hole 7 and the instrument channel 10.
[0033] Figure 3 For Figure 1 another upward view structural schematic diagram of the visible puncture scope shown in Figure 3 , the line connecting the first camera 8 and the second camera 9 is not perpendicular to the line connecting the common hole 7 and the instrument channel 10 and forms an acute angle.
[0034] Figure 4 For Figure 1 another upward view structural schematic diagram of the visible puncture scope shown in Figure 4 , at the end of the main body of the scope 6 near the needle tip, the first camera 8 and the second camera 9 are located on the same side of the line connecting the common hole 7 and the instrument channel 10. Thus, the fields of view of the first camera 8 and the second camera 9 can be superimposed in a direction parallel to or nearly parallel to the line connecting the common hole 7 and the instrument channel 10.
[0035] Figure 5 Another upward view structure schematic diagram of the visible puncture mirror shown in Figure 1 , referring to Figure 5 , the camera assembly further includes a third camera 11, and the third camera 11 is separately arranged from the first camera 8 and the second camera 9. Thus, in the embodiment of the present utility model, the images captured by any two of the first camera 8, the second camera 9, and the third camera 11 can be selectively spliced, or the images captured by the first camera 8, the second camera 9, and the third camera 11 can be spliced.
[0036] Exemplarily, at the end of the main body of the mirror tube 6 near the needle tip, the first camera 8 and the second camera 9 are located on both sides of the line connecting the common hole 7 and the instrument channel 10, the first camera 8 and the third camera 11 are located on both sides of the line connecting the common hole 7 and the instrument channel 10, and the second camera 9 and the third camera 11 are located on the same side of the line connecting the common hole 7 and the instrument channel 10.
[0037] Optionally, referring to Figure 1 and Figure 2 , the visible puncture mirror further includes an aviation plug 2 and / or an LED lamp interface 3 arranged on the side of the movable puncture needle. The aviation plug 2 is also called a display plug, and the aviation plug 2 is connected to a display device, and the display device displays the image acquired by the camera assembly.
[0038] Exemplarily, the visible puncture mirror further includes an LED lamp (not shown in the figure), and the LED lamp is used to provide an illumination beam with a certain intensity for the camera assembly for in-vivo imaging. The LED lamp interface 3 is used to supply power to the LED lamp and / or provide a control signal.
[0039] Optionally, referring to Figure 1 , the needle tip is provided with an inclined end face. Thus, it is convenient to puncture into the body with less resistance during the puncture operation.
[0040] The embodiment of the present utility model further provides a medical device, and the medical device includes the visible puncture mirror in the above embodiment.
