[0038] like Figure 1 and Figure 4As shown in the figure, the horizontal adjustment component 5 includes a limiting block 51 arranged on the bottom surface of the support rod 3. A sliding column 52 is fixedly arranged on the upper surface of the limiting block 51, and the sliding column 52 is slidably connected to the support rod 3. An installation groove 53 is formed on the sliding column 52. A connecting block 54 is slidably arranged on the inner wall of the installation groove 53, which can guide the connecting block 54 to make the vertical movement of the connecting block 54 more stable. Four insertion blocks 55 are fixedly arranged on the outer wall of the connecting block 54. A pull rod 56 is fixedly arranged at the upper end of the connecting block 54. The upper end of the pull rod 56 penetrates through the sliding column 52 and extends to the outside, which is convenient for pulling the insertion block 55 to move vertically. A second spring 57 is sleeved on the outer wall of the pull rod 56. One end of the second spring 57 is fixedly connected to the sliding column 52, and the other end of the second spring 57 is connected to the connecting block 54, which can reset the insertion block 55 and is convenient for adjusting the position of the laparoscope. A fixing plate 58 is fixedly arranged on the bottom surface of the limiting block 51, and the limiting block 51 and the fixing plate 58 are also rotatably connected, which is convenient for adjusting the fixing angle of the elastic clamping plate 59 and makes the use more convenient. Elastic clamping plates 59 are respectively fixedly arranged at both ends of the fixing plate 58, which is convenient for the stable clamping of the laparoscope.

[0039] Furthermore, a guiding groove 6 is formed in the inner wall of the support rod 21. A guiding block 7 is slidably arranged inside the guiding groove 6. The guiding block 7 is fixedly connected to the sliding rod 24, which can make the vertical movement of the sliding rod 24 more stable.

[0040] Secondly, a plurality of slots 8 are formed on the upper surface of the support rod 3, and the slots 8 can be mutually clamped with the insertion blocks 55, so as to limit the laparoscope stably.

[0041] Furthermore, a plurality of universal wheels 9 are installed on the bottom surface of the bottom plate 1, which is convenient for pulling the bottom plate 1 to move horizontally on the bottom surface and is convenient for locking to avoid movement at the same time.

[0042] In addition, the card frame 26 is arranged in a "C" - shaped structure and has elasticity, which can limit the sliding rod 24 and ensure the stability of the laparoscope.

[0043] Finally, the sizes of the elastic clamping plates 59 are different, which can stably hold the laparoscope and the laparoscope lighting lamp.

[0044] The working principle of this embodiment is as follows: Push the height adjustment component 2 to drive the universal wheels 9 at the bottom of the bottom plate 1 to slide to a suitable position and lock the universal wheels 9. Clamp the laparoscope between the larger elastic clamping plates 59, and then clamp the laparoscope lighting lamp between the smaller elastic clamping plates 59.

[0045] When adjusting the height of the laparoscope, the locking frame 26 is pulled out from the first locking slot 22 and the second locking slot 25, and the second locking slot 25 is pulled to move vertically. The second locking slot 25 is guided to move stably through the cooperation of the guide rod 23 with the guide groove 6 and the guide block 7. The second locking slot 25 drives the laparoscope, which is locked between the elastic locking plate 59, to move vertically through the support rod 3 and the angle adjustment component 4. After moving to the appropriate height, the locking frame 26 is pushed into the corresponding second locking slot 25, thereby limiting the second locking slot 25 and fixing the height of the laparoscope.

[0046] When adjusting the angle of the laparoscope, pulling the cap 47 moves the connecting rod 46, which in turn moves the toothed block 45 within the groove 44. This causes the toothed block 45, which is engaged with the gear 42, to move out. As the toothed block 45 moves, it pushes the first spring 48 to contract. Subsequently, pulling the support rod 3 causes the sleeve 43 to rotate on the outer wall of the gear 42. The support rod 3 simultaneously moves the laparoscope, which is engaged with the elastic plate 59. Once the laparoscope has moved to the appropriate angle, the second spring 57 is released. The elastic force of the first spring 48 pushes the toothed block 45 to engage with the corresponding gear 42, thus fixing the adjusted angle of the laparoscope.

[0047] When adjusting the horizontal position of the laparoscope, pulling rod 56 moves it vertically upwards. Rod 56, through connecting block 54, moves insert block 55 out of slot 8. Then, pulling rod 56 moves it horizontally. Rod 56, through sliding post 52 and limiting block 51, moves elastic locking plate 59 horizontally. Elastic locking plate 59 moves the engaged laparoscope. Once the laparoscope is in the appropriate position, releasing rod 56 allows the second spring 57 to push connecting block 54, causing insert block 55 to engage in the corresponding slot 8, thus stabilizing and limiting the laparoscope's position.

[0048] It can reduce the impact of hand tremors and fatigue of doctors or assistants on the position and angle of the laparoscope, improve the stability and accuracy of the surgery, optimize the surgical perspective, avoid obstruction, improve the surgical effect, and reduce the surgical risk.

[0049] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
