[0042] The following describes the technical solutions provided by each embodiment of this application in conjunction with the accompanying drawings.

[0043] Refer to Figures 1 to 7 , the present invention provides an endoscope snake bone coating tube, which is characterized by comprising: a plurality of outer snake bone shells 1, an intermediate protective layer 6 and an inner layer 7. The plurality of outer snake bone shells 1 are connected in sequence. The outer snake bone can be used to provide protection for the present invention. The outer snake bone shell 1 has high wear resistance and corrosion resistance, and its exterior is coated with a hydrophilic layer to reduce friction.

[0044] The material of the intermediate protective layer 6 can be but is not limited to a fiber woven fabric, which has flexibility and improves the overall structural stability. The inner layer 7 is relatively smooth.

[0045] In Figures 1 to 7 In an alternative embodiment, the outer snake bone shell 1 is in the shape of a hollow cylinder. One end of the outer snake bone shell 1 is circumferentially arrayed around the axis of the outer snake bone shell 1 and is provided with two rotation docking grooves 11 and two arc-shaped notch grooves 12 at intervals. The other end of the outer snake bone shell 1 is provided with a rotation docking block 13.

[0046] It should be noted that there are multiple outer snake bone shells 1, one end of each outer snake bone shell 1 is connected to the other end of the next outer snake bone shell 1. When the endoscope snake bone coating tube rotates, the rotating docking block 13 rotates in the rotating docking groove 11.

[0047] Furthermore, the outer snake bone shell 1 includes a first outer shell 14 and a second outer shell 15. A sliding block 17 is arranged in the first outer shell 14, and a sliding groove 16 is provided in the second outer shell 15. A first connecting block 18 is arranged on the inner wall of the first outer shell 14, and a second connecting block 19 is arranged on the inner wall of the second outer shell 15. The first outer shell 14 is slidably connected to the second outer shell 15. By moving the first outer shell 14 in the second outer shell 15, the outer snake bone shell 1 can freely adjust its length.

[0048] Meanwhile, it should be noted that an auxiliary sliding rod is connected to the arc-shaped notch groove 12. There is a notch inside the second outer shell 15, and the auxiliary sliding rod is slidably connected to the notch. When multiple outer snake bone shells 1 rotate, the auxiliary sliding rod can move in the notch, thus playing a role in auxiliary connection.

[0049] In Figures 1 to 7 In an alternative embodiment, the multi-stage telescopic mechanism 2 includes a motor 21, a fixed housing 22, a first screw 23, and multiple telescopic components 3. The fixed housing 22 is connected to the first connecting block 18 of the first outer snake bone shell 1. The fixed housing 22 is connected to the motor 21, the output end of the motor 21 is connected to the first screw 23, and the first screw 23 is connected to the telescopic component 3. The motor 21 is used to control the extension / shortening of the height of each outer snake bone shell 1.

[0050] Furthermore, each telescopic component 3 includes a telescopic housing 31, a fixed clamping block 32, and a hollow screw 33.

[0051] Furthermore, the outer surface of the first telescopic housing 31 is slidably connected to the fixed housing 22, the bottom end of the first telescopic housing 31 is slidably connected to the first screw 23. The outer surface of the latter telescopic housing 31 is slidably connected to the previous telescopic housing 31, and the inner wall of the hollow screw 33 of the latter telescopic housing 31 is threadedly connected to the outer side of the previous telescopic housing 31. When the motor 21 drives the first screw 23 to rotate, multiple telescopic housings 31 extend / retract.

[0052] Furthermore, the outer diameter of the previous telescopic housing 31 is smaller than the inner diameter of the latter telescopic housing 31, and the outer diameter of the previous hollow screw 33 is the same as the inner diameter of the latter hollow screw 33.

[0053] Specifically, when the motor 21 rotates, the first screw 23 is driven to rotate. Since the first screw 23 is threadedly connected to the inner wall of the first hollow screw 33, the first hollow screw 33 rotates accordingly. And the outer wall of the first hollow screw 33 is threadedly connected to the inner wall of the next hollow screw 33. Therefore, as the motor 21 rotates, the multi-stage telescopic mechanism 2 can extend / retract.

[0054] Furthermore, one end of each telescopic housing 31 is fixed to the second connecting block 19 of the previous outer snake bone housing 1, and the other end of each telescopic housing 31 is fixed to the first connecting block 18 of the next outer snake bone housing 1. Thus, the multi-stage telescopic mechanism 2 can drive the movement of the first outer housing 14 and the second outer housing 15.

[0055] It should be noted that there are two multi-stage telescopic mechanisms 2, and the two multi-stage telescopic mechanisms 2 are arranged oppositely. When one side of the multi-stage telescopic mechanism 2 is activated, the endoscopic snake bone covering tube moves to the other side. When the multi-stage telescopic mechanism 2 on the other side is activated, the endoscopic snake bone covering tube moves to one side.

[0056] Furthermore, a pressure sensor 4 is provided on each outer snake bone housing 1. The pressure sensor 4 is used to detect the pressure on the outer surface of the endoscopic snake bone covering tube.

[0057] Furthermore, the protective cover 5 is connected to the first outer snake bone housing 1, and the motor 21 is connected to the protective cover 5.

[0058] Furthermore, an intermediate protective layer 6 and an inner layer 7 are sequentially provided on the inner wall of the outer snake bone housing 1.

[0063] S2: Assemble each outer snake bone housing 1 and install the multi-stage telescopic mechanism 2;

[0064] Install each produced outer snake bone housing 1. Specifically, the rotary docking block 13 of the previous outer snake bone housing 1 is rotatably connected to the rotary docking groove 11 of the next outer snake bone housing 1. The outer snake bone housing 1 is provided with a first connection block 18 and a second connection block 19. The multi-stage telescopic mechanism 2 is connected to the first connection block 18 and the second connection block 19, and the multi-stage telescopic mechanism 2 controls the elongation / shortening of each outer snake bone housing 1. The multi-stage telescopic mechanism 2 can also control the rotational movement of the present invention.

[0065] S3: Install the intermediate protective layer 6 and the inner layer 7.

[0066] Connect the intermediate protective layer 6 and the inner layer 7 to the inner end of the outer snake bone housing 1 in sequence.

[0067] An endoscope snake bone coating tube and its processing method of the present invention are as follows:

[0068] Produce a plurality of outer snake bone housings 1 by injection molding. The rotary docking block 13 of the previous outer snake bone housing 1 is rotatably connected to the rotary docking groove 11 of the next outer snake bone housing 1. The outer snake bone housing 1 is provided with a first connection block 18 and a second connection block 19. The multi-stage telescopic mechanism 2 is connected to the first connection block 18 and the second connection block 19. By extending / retracting the multi-stage telescopic mechanism 2 provided on both sides of the outer snake bone housing 1, the multi-stage telescopic mechanism 2 can drive the rotation of the first screw 23 through the rotation of the motor 21, and the first screw 23 drives the hollow screw 33 to rotate, so that the multi-stage telescopic mechanism 2 extends / retracts. When one side of the multi-stage telescopic mechanism 2 is activated, the endoscope snake bone coating tube moves to the other side. When the multi-stage telescopic mechanism 2 on the other side is activated, the endoscope snake bone coating tube moves to one side. The rotational movement of the present invention can be controlled. This design can control the flexible steering of the device by driving the motor 21.

[0069] By providing a first outer housing 14 and a second outer housing 15 on the outer snake bone housing 1, the first outer housing 14 and the second outer housing 15 can be elongated / shortened under the drive of the multi-stage telescopic mechanism 2. This design can improve the matching of the device in different usage environments.
