Specifically, the first connecting pipe section 32 and the second connecting pipe section 33 are threadedly connected to the end of the attraction main rod 1 and the end of the attraction rod head 2, respectively. In other embodiments, the first connecting pipe section 32 and the second connecting pipe section 33 are welded and fixed to the attraction main rod 1 and the attraction rod head 2, respectively.

[0040] Reference Figure 1 , Figure 2 The end of the suction main rod 1 away from the suction rod head 2 is coaxially fixedly connected with a pagoda joint 11 for connecting with the sputum suction device, and the suction main rod 1 is provided with an adjustment member 4 for driving the suction rod head 2 to slide relative to the suction main rod 1. The adjustment member 4 includes an adjustment rod 41 and a thrust button 42, one end of the adjustment rod 41 is fixedly connected to the suction rod head 2, the other end of the adjustment rod 41 is axially slidably connected to the suction main rod 1, and the thrust button 42 is fixedly connected to the outer wall of the adjustment rod 41 away from the suction main rod 1, and the outer side wall of the thrust button 42 has anti-slip patterns.

[0041] The specific installation structure of the adjustment rod 41 and the attraction rod head 2 is as follows: the attraction rod head 2 is protruded and fixedly connected with a mounting block 22 on the outer peripheral wall of the end near the attraction main rod 1, and the mounting block 22 has a mounting groove 23, and the notch of the mounting groove 23 extends to the side of the mounting block 22 away from the attraction rod head 2, so that the mounting block 22 is U-shaped. The end of the adjustment rod 41 is clamped in the mounting groove 23, and the end of the adjustment rod 41 is provided with a through hole 43, and the mounting block 22 is provided with a first pin 24 that penetrates the through hole 43.

[0042] The specific installation structure of the adjustment rod 41 and the attraction main rod 1 is as follows: the outer peripheral wall of the attraction main rod 1 protrudes and is fixedly connected with a guide block 12, and the guide block 12 has a guide groove 13, and the notch of the guide groove 13 extends to the side of the guide block 12 away from the attraction main rod 1, so that the guide block 12 is U-shaped, and the adjustment rod 41 is slidably penetrated in the guide groove 13. The outer wall of the adjustment rod 41 is provided with a first slide groove 44 along the length direction, and the guide block 12 is fixedly connected with a second pin 14 slidably penetrated in the first slide groove 44.

[0043] Reference Figure 1 , Figure 3The outer wall of one end of the attraction main rod 1 close to the pagoda joint 11 is fixedly connected to a limiting block 15, and the limiting block 15 has a limiting groove 16 for the adjusting rod 41 to slide axially through.

In this embodiment, the limiting member is a first top screw 51 threadedly penetrated through the limiting block 15, and the end of the first top screw 51 is pressed against the outer wall of the adjusting rod 41.

[0044] The implementation principle of a retractable subendoscopic aspirator in the embodiment of the present application is as follows: under normal conditions, the end of the first top screw 51 is pressed against the outer wall of the adjustment rod 41 to limit the sliding of the adjustment rod 41 in the form of damping. During the operation, when the length of the aspirator needs to be adjusted, the first top screw 51 is loosened to release the sliding restriction of the first top screw 51 on the adjustment rod 41, and the thrust button 42 is pushed by the finger to push the adjustment rod 41 to slide, thereby adjusting the relative position of the suction rod head 2 and the suction main rod 1, and the retractable bellows 3 is adapted to be retracted and adjusted, thereby realizing the adjustment of the length of the aspirator and improving the convenience of operation. After the adjustment is completed, the first top screw 51 is locked to ensure that when the length of the aspirator is adjusted in place, it can remain stable without being disturbed by a small external force. The suction main rod 1 is externally connected to a sputum suction device, which forms a negative pressure area in the inner cavity of the suction main rod 1, the suction rod head 2 and the retractable bellows 3, and physiological saline and fine synovial debris are discharged from the body through the suction hole 21, the suction rod head 2, the retractable bellows 3, and the suction main rod 1 in turn.

The elastic resistance-increasing pad 52 is a rubber pad, which increases the sliding friction between the limiting block 15 and the adjusting rod 41. When the adjusting rod 41 needs to slide, the operator needs to apply a greater force to the adjusting rod 41 to make the adjusting rod 41 slide, so as to ensure that when the length of the attractor is adjusted into place, it can remain stable without being disturbed by smaller external forces.

[0047] Embodiment 3:

[0048] The difference from Example 1 is that, referring to Figure 5 , Figure 6 The notch of the limit groove 16 extends to the side of the limit block 15 away from the attraction main rod 1, so that the limit block 15 is U-shaped, and the first side wall of the limit block 15 is penetrated by a second top screw 53, and the side wall of the adjustment rod 41 is penetrated by a second slide groove 45 extending along the axial direction, and the second top screw 53 is penetrated by the second slide groove 45, and the end of the second top screw 53 is threadedly penetrated by the second side wall of the limit block 15, and the head of the second top screw 53 abuts against the first side wall of the limit block 15.

[0049] By tightening the second top screw 53, the head of the second top screw 53 is screwed inward toward the second side wall, thereby driving the first side wall and the second side wall to deform toward each other and press against the outer wall of the adjustment rod 41, clamping the adjustment rod 41, thereby limiting the slippage of the adjustment rod 41.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
