[0028] See also Figures 1 to 5 , Figure 1It is a schematic diagram of the three-dimensional structure of the endoscope tip of the utility model. The endoscope tip 10 is used to connect with the endoscope snake bone. The endoscope tip 10 is used to carry LED lamp beads and cameras. Instruments such as forceps channel tubes also need to pass through the endoscope tip 10. The endoscope tip 10 has two opposite ends along the axial direction. For the convenience of description, the end of the endoscope tip 10 facing the lesion and away from the operator is called the first end 100, which is also the front end of the endoscope tip 10, and the end away from the lesion and close to the operator is called the second end 200, which is also the rear end of the endoscope tip 10. The first end 100 of the endoscope tip 10 is provided with an instrument channel hole 11, an LED lamp bead slot 12, a camera slot 13 and an installation slot 14 along the axial direction, wherein the instrument channel hole 11 is used for passing medical surgical instruments, the LED lamp bead slot 12 is used to install LED lamp beads, and the camera slot 13 is used to install the camera. The instrument channel hole 11, the camera slot 13 and the installation slot 14 penetrate the endoscope tip 10, and the installation slot 14 intersects with the LED lamp bead slot 12. The installation slot 14 is used to allow the LED lamp bead to pass through the second end 200 of the endoscope tip 10, move to the first end 100, and then be installed in the LED lamp bead slot 12. The above arrangement allows external instruments to be inserted from the second end 200 into the first end 100 for operation, and allows the camera to be inserted from the second end 200 into the camera slot 13 of the first end 100 for installation and fixation. The LED lamp bead moves from the rear end of the endoscope tip 10 to the front end through the installation slot 14. Since the installation slot 14 intersects with the LED lamp bead slot 12, the LED lamp bead is passed out of the endoscope tip 10 and then rotated to correspond to the LED lamp bead slot 12, and then placed into the LED lamp bead slot 12, so that the LED lamp bead can be installed. The above arrangement enables the LED lamp bead to be inserted from the rear end of the endoscope tip 10 for fixed installation. When the connecting wire of the LED lamp bead is integrated with the connecting wire of the camera, the defect that the LED lamp bead cannot be installed from the rear end of the endoscope tip 10 can be avoided.

[0029] The LED lamp bead groove 12 and the mounting groove 14 surround the camera groove 13, thereby providing balanced lighting after the LED lamp bead is installed.

[0030] The instrument channel hole 11, LED lamp bead slot 12, camera slot 13 and mounting slot 14 in the present application are closely adjacent to each other so as to minimize the occupied space and reduce the external dimensions of the endoscope tip. The shape of the instrument channel hole 11 can be set to be circular or elliptical for the purpose of facilitating the passage of instruments. The shapes of the LED lamp bead slot 12 and the camera slot 13 are similar to the shapes of the LED lamp beads and cameras used, and the sizes are slightly larger than the sizes of the components, so as to minimize the space occupied inside.

[0031] In the present application, the mounting groove 14 intersects with the middle of the LED lamp bead groove 12, the middle of the LED lamp bead groove 12 passes through the endoscope end 10 to form a hollow, and mounting steps are formed at both ends. The two mounting steps are symmetrically distributed with the center line of the mounting groove 14 as the center, so that the force on the LED lamp bead is balanced after installation.

[0032] There are multiple options for the position of the mounting groove 14 and the LED lamp bead groove 12 in the present application. In the first embodiment, the middle of the mounting groove 14 along the length direction intersects with the LED lamp bead groove 12. Figure 2 In the second and third embodiments, the end of the mounting groove 14 along the length direction intersects with the LED lamp bead groove 12, see Figure 3 and Figure 4 In this case, the position of the LED lamp bead slot 12 is set relatively inward or outward. Under the above three settings, the external dimensions of the endoscope tip 10 remain unchanged, and the position of the horizontal mounting slot 14 also remains unchanged. Only the position of the LED lamp bead slot 12 is adjusted, and it can be selected according to different needs in specific applications.

[0033] The cross-sectional shape of the LED lamp bead slot 12 in the present application is a rectangle, which is suitable for rectangular LED lamp beads. The cross-sectional shape of the mounting slot 14 is any one of a rectangle, a circle, and an irregular polygon. Preferably, the cross-sectional shape of the mounting slot 14 in the present application is the same as that of the LED lamp bead slot 12, which is also a rectangle.

[0034] In the present application, the width of the mounting groove 14 is greater than the external dimensions of the LED lamp beads, so that the LED lamp beads can pass through the mounting groove 14. The width of the LED lamp bead groove 12 is greater than or equal to the external dimensions of the LED lamp beads, so that the LED lamp beads can be installed in the LED lamp bead groove 12. The side walls of the LED lamp bead groove 12 restrict the LED lamp beads to prevent the LED lamp beads from shaking when the endoscope tip 10 is used. The depth of the LED lamp bead groove 12 is equal to the height of the LED lamp bead, so that the light-emitting surface of the LED lamp bead is flush with the endoscope tip 10 after the LED lamp bead is installed in the LED lamp bead groove 12.

[0035] In the present application, the mounting groove 14 is arranged perpendicularly to the LED lamp bead groove 12, so as to facilitate the adjustment of the direction when installing the LED lamp bead. The LED lamp bead enters the mounting groove 14 from the rear end of the endoscope tip 10, moves along the mounting groove 14 to the outside of the first end 100, and then rotates 90 degrees and moves backward to enter the LED lamp bead groove 12.

[0036] In this application, the LED lamp bead slot 12 is connected to the camera slot 13, such as Figure 5As shown, in the fourth embodiment, one end of the LED lamp bead slot 12 close to the camera slot 13 is connected to the camera slot 13, so that the LED lamp bead slot 12, the camera slot 13 and the installation slot 14 are all connected, which is convenient for wiring.

[0037] In the present application, the number of LED lamp bead slots 12 and mounting slots 14 are both two, and they are symmetrically arranged on both sides of the camera slot 13. In order to make the lighting clearer, the number of +LED lamps is set to two, and one LED lamp is arranged on the left and right of the camera slot 13 respectively, so that the lighting covers a wider area and avoids shadows on the sides of the camera to affect the line of sight.
