[0034] The gripping part 1 has a first hollow inner cavity 101, and the shape of the space inside the first hollow inner cavity 101 can be a cylinder.
[0035] The rod 2 has a second hollow inner cavity 201, one end of which is connected to the gripping part 1, and the other end extends away from the gripping part 1. It includes a holding part 21 and a swinging part 22 located at the far end of the rod 2. The holding part 21 can be made of a rigid material, and the swinging part 22 can be made of a flexible material, thereby ensuring that the swinging part 22 can swing relative to the holding part 21. The space inside the second hollow inner cavity 201 can be cylindrical.
[0036] The hook 3 is located at the end of the swing part 22. The hook 3 can be made of a rigid material that can pull the trachea.
[0037] The bending structure includes a guide post 41, a first slider 42, a second slider 43, a first traction wire 44, a second traction wire 45, a first driving member 46, and a second driving member 47. The first slider 42 and the second slider 43 can be cylindrical. The guide post 41 is disposed in the first hollow inner cavity 101 and extends from the proximal end to the distal end. The first slider 42 and the second slider 43 are sleeved on the guide post 41. The first slider 42 and the second slider 43 can move along the guide post 41 from the proximal end to the distal end, or from the distal end to the proximal end. One end of the first traction wire 44 is fixedly connected to the first slider 42, and one end of the second traction wire 45 is fixedly connected to the second slider 43. The other ends of the first traction wire 44 and the second traction wire 45 extend from the first hollow inner cavity 101 to the second hollow inner cavity 201 and connect to the swing part 22. The first traction wire 44 can be set on the first side of the first hollow inner cavity 101 and the second hollow inner cavity 102, and the second traction wire 45 can be set on the second side of the first hollow inner cavity 101 and the second hollow inner cavity 102 opposite to the first side. When the first traction wire 44 pulls the swing part 22, the swing part 22 deflects in the first direction. When the second traction wire 45 pulls the swing part 22, the swing part 22 deflects in the second direction opposite to the first direction, so as to flexibly control the hook body 3 to pull the air tube in the first direction or the second direction according to actual needs. The first driving member 46 is disposed on the grip portion and is drivenly connected to the first slider 42. The first slider 42 is controlled by the first driving member 46 to reciprocate between the proximal end and the distal end. The second driving member 47 is disposed on the grip portion and is drivenly connected to the second slider 43. The second slider 43 is controlled by the second driving member to reciprocate between the proximal end and the distal end.
[0038] The hook 3 can be used to pull the trachea. The first driving member 46 can drive the first slider 42 to move proximally or distally along the guide post 41, and one end of the first traction wire 44 can move proximally or distally. The other end of the first traction wire 44 drives the swing part 22 to deflect or reset in the first direction. The second driving member 47 can drive the second slider 43 to move proximally or distally along the guide post 41, and one end of the second traction wire 45 can move proximally or distally. The other end of the second traction wire 45 drives the swing part 22 to deflect or reset in the second direction opposite to the first direction. In use, medical staff can use the hook 3 to hook the trachea, and then use the first driving member 46 or the second driving member 47 to control the deflection direction of the swing part 22. The hook 3 will pull the trachea away from the thyroidectomy site, avoiding the trachea from obstructing the surgical field of vision or hindering the surgical operation, ensuring the smooth progress of the operation, and improving the safety and efficiency of the operation.
[0039] like Figure 2 and Figure 5 As shown, in this embodiment, the cross-sectional shape of the guide post 41 is rectangular, the first slider 42 has a first through hole that slides with the guide post 41, and the second slider 43 has a second through hole that slides with the guide post 41.

Rotating the first driving member 46 can drive the first slider 42 to move towards the proximal end or the distal end. For example, rotating the first driving member 46 clockwise will move the first slider 42 towards the proximal end, and rotating the first driving member 46 counterclockwise will move the first slider 42 towards the distal end.
[0044] The second driving member 47 is a cylindrical structure and is rotatably mounted on the second annular notch. The inner wall of the second driving member 47 is provided with a second internal thread, and the outer edge of the second slider 43 is provided with a second external thread that mates with the second internal thread. Rotating the second driving member 47 can drive the second slider 43 to move towards the proximal end or the distal end. For example, rotating the second driving member 47 clockwise will move the second slider 43 towards the proximal end, and rotating the second driving member 47 counterclockwise will move the second slider 43 towards the distal end.
[0045] like Figure 2 As shown, in this embodiment, the gripping part 1 has a distal end cap 11 and a proximal end cap 12 fixedly connected to both ends of the guide post 41, and also includes a boss 13 disposed between the distal end cap 11 and the proximal end cap 12.

The distal end cap 11 can be integrally formed with the rod body 2, and the boss 13 can be fitted onto the guide post 41. The proximal end of the guide post 41 can be provided with an external thread, and the proximal end cap 12 can be provided with a threaded hole that mates with the guide post 41, thereby assembling the components in sequence.
[0046] like Figure 3 and Figure 4 As shown, in this embodiment, a second through hole 131 is provided on the boss 13 at the position corresponding to the first through hole 421. The second traction wire 45 passes through the second through hole 131 and extends to the end face of the second slider 43, thereby avoiding the boss 13 from obstructing the extension of the second traction wire 45, so that the second traction wire 45 can move freely.
[0047] In this embodiment, the distal cap 11 is provided with a first traction channel and a second traction channel that connect the first hollow inner cavity 101 and the second hollow inner cavity 201. The first traction wire 44 passes through the first traction channel and the second traction wire 45 passes through the second traction channel.
[0048] like Figure 2 and Figure 4As shown, in this embodiment, the opposite end faces of the first driving member 46 in the axial direction are all planar, the distal end cap 11 has a first plane that mates with the first driving member 46, the boss 13 has a second plane that mates with the second driving member 47, the opposite end faces of the second driving member 47 in the axial direction are all planar, the proximal end cap 12 has a third plane that mates with the second driving member 47, and the boss 13 has a fourth plane that mates with the second driving member 47.
[0049] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the hook tongue of the hook body 3 is rectangular or fan-shaped, and the hook tongue of the hook body 3 has a certain length and width. The surface of the hook tongue that contacts the trachea is arc-shaped to avoid damage to the trachea.
[0050] In this embodiment, the width of the hook tongue ranges from 0.5cm to 2cm. Within this range, it can ensure that the hook tongue can firmly hook the trachea, while also making the size small enough to facilitate precise operation by medical staff.
[0051] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
