[0032] Embodiment one

[0033] As shown in Figures 1-6 , a winding embedded buckle snake bone includes a hollow pipe body 1;

[0034] The hollow pipe body 1 is provided with a cutting gap 2;

[0035] The cutting gap 2 divides at least a portion of the hollow pipe body 1 into a helix 3 extending in a spiral shape and coiled;

[0036] A plurality of first spiral buckles 4 extending from outside to inside in a spiral manner are sequentially arranged on one side edge of the helix 3;

[0037] A plurality of second spiral buckles 5 extending from outside to inside in a spiral manner are sequentially arranged on the other side edge of the helix 3;

[0038] The first spiral buckle 4 and the corresponding second spiral buckle 5 are wound and matched to form a rotary joint 100; specifically, when the hollow pipe body 1 is subjected to an axial tension, due to the wound and matched first spiral buckle 4 and second spiral buckle 5 forming a wound embedded buckle structure, the first spiral buckle 4 can hook the second spiral buckle 5 that is wound with each other, thereby preventing the first spiral buckle 4 and the second spiral buckle 5 from being decoupled, and can well disperse the axial tension, improve the resistance to the axial tension, and prevent the decoupling phenomenon from occurring. In addition, the contact area of the first spiral buckle 4 and the second spiral buckle 5 is also increased, which can increase the radial force that can be borne.

[0039] As shown in Figures 1-6 The rotary joint 100 is sequentially and spirally spaced along the spiral extension direction of the cutting gap 2.

[0040] As shown in Figures 1-6 The rotary joint 100 is distributed on the pipe wall of the hollow pipe body 1 to form two joint groups that are spaced 180° apart, and the rotary joints 100 in each joint group are sequentially arranged in a straight line along the axial direction of the hollow pipe body 1. Specifically, the interval angle A between any two adjacent rotary joints 100 along the spiral extension direction of the cutting gap 2 is 180°, which can make the rotary joints 100 in the two joint groups sequentially arranged in a straight line along the axial direction of the hollow pipe body 1. In this case, the hollow pipe body 1 will not deviate when being bent and can always be bent in a plane, as shown in Figure 6 The maximum bending angle of the hollow pipe body 1 is 270°, and the hollow pipe body 1 will be in contact with itself when being bent to 270°. This embodiment can be applied to natural cavities in a living body with a bending angle of less than 270°, and can be bent in a smaller space. The non-deviation feature after bending can make the operation of the snake bone more convenient and intuitive during the operation or examination process.

[0041] As shown in Figures 1-5 The first spiral buckle 4 and the corresponding second spiral buckle 5 are wound and matched to form a rotary joint 100; specifically, when the hollow pipe body 1 is subjected to an axial tension, due to the wound and matched first spiral buckle 4 and second spiral buckle 5 forming a wound embedded buckle structure, the first spiral buckle 4 can hook the second spiral buckle 5 that is wound with each other, thereby preventing the first spiral buckle 4 and the second spiral buckle 5 from being decoupled, and can well disperse the axial tension, improve the resistance to the axial tension, and prevent the decoupling phenomenon from occurring. In addition, the contact area of the first spiral buckle 4 and the second spiral buckle 5 is also increased, which can increase the radial force that can be borne.

[0042] As shown in Figures 1-5 The first spiral buckle 4 has a first end head;

[0043] The second spiral buckle 5 has a second end head;

[0044] The first end head and the second end head are provided with a movable interval 6 for relative rotation of the first spiral buckle 4 and the second spiral buckle 5.

[0045] As shown in Figures 1-3 The hollow pipe body 1 also includes an upper cylindrical portion 7, and the upper end of the spiral body 3 is connected to the upper cylindrical portion 7. The hollow pipe body 1 also includes a lower cylindrical portion 8, and the lower end of the spiral body 3 is connected to the lower cylindrical portion 8.

[0046] As shown in Figures 1-5 The first spiral buckle 4 and the second spiral buckle 5 respectively extend clockwise from outside to inside, and the spiral direction of the spiral body 3 is right-handed.

[0052] A plurality of second spiral buckles 5 extending from outside to inside are sequentially arranged on the other side edge of the spiral body 3;

[0053] The first spiral buckle 4 and the corresponding second spiral buckle 5 are wound and matched to form a rotary joint 100. Specifically, when the hollow pipe body 1 is subjected to an axial tension, the first spiral buckle 4 and the second spiral buckle 5 are wound and matched to form a winding embedded buckle structure, the first spiral buckle 4 can hook the second spiral buckle 5 wound with each other, thereby preventing the first spiral buckle 4 and the second spiral buckle 5 from being disconnected, and the axial tension can be well dispersed, the resistance to axial tension is improved, and the disconnection phenomenon is prevented. In addition, the contact area of the first spiral buckle 4 and the second spiral buckle 5 is also increased, which can increase the radial force that can be borne.

[0055] As shown in Figures 7-9As shown, the rotary joints 100 are distributed on the tube wall of the hollow tube body 1 to form two joint groups separated by 180°, and the rotary joints 100 in each joint group are arranged in a spiral shape in the same rotation direction on the tube wall of the hollow tube body 1. Specifically, the interval angle A between any two adjacent rotary joints 100 along the spiral extension direction of the cutting gap 2 is greater than or less than 180°, which can enable the rotary joints 100 in the two joint groups to be arranged in a spiral shape in the same rotation direction on the tube wall of the hollow tube body 1. Figure 8 As shown, the interval angle A between any two adjacent rotary joints 100 along the spiral extension direction of the cutting gap 2 is greater than or less than 180°, which can enable the rotary joints 100 in the two joint groups to be arranged in a spiral shape in the same rotation direction on the tube wall of the hollow tube body 1. Figure 7 As shown, the interval angle A between any two adjacent rotary joints 100 along the spiral extension direction of the cutting gap 2 is greater than or less than 180°, which can enable the rotary joints 100 in the two joint groups to be arranged in a spiral shape in the same rotation direction on the tube wall of the hollow tube body 1. Figure 9 As shown, the interval angle A between any two adjacent rotary joints 100 along the spiral extension direction of the cutting gap 2 is greater than or less than 180°, which can enable the rotary joints 100 in the two joint groups to be arranged in a spiral shape in the same rotation direction on the tube wall of the hollow tube body 1.

[0056] In this embodiment, the first spiral buckle 4 and the corresponding second spiral buckle 5 are gap-wound and matched, so that the first spiral buckle 4 and the corresponding second spiral buckle 5 can rotate relative to each other smoothly.

[0057] In this embodiment, the first spiral buckle 4 has a first end head;

[0058] The second spiral buckle 5 has a second end head;

[0059] The first end head and the second end head are provided with a movable interval 6 for relative rotation of the first spiral buckle 4 and the second spiral buckle 5.

[0060] In this embodiment, the hollow tube body 1 further includes an upper cylindrical portion 7, and the upper end of the spiral body 3 is connected to the upper cylindrical portion 7.
