Embodiment 1
[0046] like Figure 1-11 , 17 and 18 show
[0047] An adjustable channel for unilateral double-channel endoscopic nucleus pulposus in the present invention comprises a side panel (3), an adjustment block (2) and a vertical frame (1). hole, the middle of the side wings is provided with a plurality of adjustment blocks (2), the adjustment blocks (2) are arranged in a circular array around the center of the through hole of the side wing plate (3), and the adjustment blocks (2) are slidably connected to each other. The two side faces of the adjustment block (2) sliding mutually form an acute angle, and the lower side of the adjustment block (2) is provided with a corresponding vertical frame (1), and the shape of the vertical frame (1) is consistent with that of the adjustment block (2). A length adjustment assembly is arranged between the vertical frame (1) and the adjustment block (2), and the length adjustment assembly adjusts the distance between the vertical frame (1) and th...
Embodiment 2
[0054] like Figure 1-11 , 17 and 18 show
[0055] As described in Example 1, the side flaps are rotated clockwise relative to the longitudinal frame, so that the longitudinal frames slide toward each other and move outward, increasing the diameter of the channel. In the case of obese patients or thicker tissues, the effect of exposing the target position is also achieved. Meet the requirements for adapting to the purpose of patient size.
Embodiment 3
[0057] like Figure 12-14 shown
[0058] The length adjustment assembly includes a slider (201), a telescopic air bag (205) and a tension spring (206), the upper side of the vertical frame (1) has a chute (101), and the lower side of the adjustment block (2) A slider (201) is fixedly connected, and the slider (201) is slidably connected in the chute (101), and one of the adjusting blocks (2) is set as a thin plate (204), and the adjusting block (2) is lowered A telescopic air bag (205) is fixedly connected to one side of the thin plate (204), and a tension spring (206) is fixedly connected to the lower side of the adjustment block (2) on the side of the telescopic air bag (205). By controlling the telescopic air bag (205) Adjust the distance between the adjustment block (2) and the vertical frame (1), the upper side of the telescopic air bag (205) is fixedly connected with a connecting pipe (207), and the connecting pipe (207) is fixedly connected upward with a vertical pipe ...
