A pull rod 505 is fixedly connected to the front end of the presentation board 504. The mouse and keyboard for operating the display screen 11 can be placed on the presentation board 504. The presentation board 504 is pulled by the pull rod 505 to store the control hardware to prevent the control hardware from falling when the surgical teaching cart moves and causing hardware damage. An L-shaped groove 9 is provided on the left side surface of the outer shell 1. Support mechanisms 7 are fixedly connected to the lower end surfaces of the left and right sides of the outer shell 1. Several moving mechanisms 8 are arranged around the lower end of the outer shell 1 to prevent the surgical teaching cart from tipping over due to a change in the center of gravity and to stabilize the entire teaching cart.

[0027] In one embodiment, Figure 2 and Figure 4As shown, the camera angle adjustment mechanism 6 includes a first adjustment rod 601 rotatably connected to the upper end of the connecting frame 4, the other end of the first adjustment rod 601 is rotatably connected to the first rotating base 602, the output end of the first rotating base 602 is rotatably connected to the second adjustment rod 603, the other end of the second adjustment rod 603 is rotatably connected to the third adjustment rod 604, the other end of the third adjustment rod 604 is fixedly connected to a camera 605, and the outer surface of the third adjustment rod 604 is fixedly connected to a control rod 10. Through the camera angle adjustment mechanism 6, the camera angle of the camera 605 can be freely adjusted, the surgical process can be displayed more comprehensively, and the trainee medical staff can learn the details of the surgery from any angle. The control rod 10 can prevent the operator from directly holding the camera 605 to adjust when adjusting the camera angle. This causes damage to the camera 605. The support mechanism 7 includes a telescopic fence 701 fixedly connected to the lower ends of the left and right sides of the outer shell 1. The end of the telescopic fence 701 away from the outer shell 1 is fixedly connected to a support rod 702. Both ends of the support rod 702 are rotatably connected to a stabilizing rod 703. The other end of the stabilizing rod 703 is provided with a slider 704. The slider 704 is slidably set inside the L-shaped groove 9. When the camera angle adjustment mechanism 6 is moved, the center of the entire teaching cart will be offset. At this time, the telescopic fence 701 is stretched to make the slider 704 slide inside the L-shaped groove 9 until the slider 704 slides to the bottom of the L-shaped groove 9 and is engaged with the shorter side of the L-shaped groove 9. At this time, the support rod 702 forms a stable triangular structure with the outer shell 1 and the telescopic fence 701, which can play a supporting role when the teaching cart topples over.

[0028] In one embodiment, Figure 5 and Figure 6As shown, the moving mechanism 8 includes a rotating block 801 rotatably connected to the surrounding positions of the lower end of the outer shell 1, the lower end of the rotating block 801 is fixedly connected to the support shell 802, the right side of the support shell 802 is rotatably connected to the roller 803, and the left side of the support shell 802 is provided with a switching mechanism 81. The switching mechanism 81 includes a protrusion 811 that passes through the upper left end of the support shell 802, the lower end of the protrusion 811 is fixedly connected to the support block 812, and the lower end of the support block 812 is provided with a plurality of anti-skid grooves 501. The upgrade of the anti-skid grooves 501 makes the support more stable and less likely to slide. The front and rear ends of the protrusion 811 are provided with first limiting grooves 813, and the first limiting grooves 813 are fixedly connected and provided with a plurality of first return springs 814 inside. The first return springs 814 are also provided with a plurality of first return springs 814. The first end of the support block 812 is fixedly connected with a first limit block 815, the cross section of the first limit block 815 is inverted trapezoidal, the first limit block 815 is clamped in the first limit groove 813, the left end of the support block 812 is provided with a second limit groove 816, the second limit groove 816 is fixedly connected with a plurality of second return springs 817, the other end of the second return spring 817 is fixedly connected with a second limit block 818, the second limit block 818 is clamped in the second limit groove 816, and the left end of the support shell 802 is provided with a second limit groove 816. The limiting opening 819 and the limiting sleeve 8110 are fixedly connected to the upper left end of the support shell 802. When the teaching cart needs to be moved, the first limiting block 815 is clamped in the limiting sleeve 8110, and the support block 812 is inside the support shell 802. At this time, the second return spring 817 is compressed, and the second limiting block 818 is located inside the support shell 802. When the teaching cart needs to be firmly fixed, the protrusion 811 is stepped on, and the inclined surface at the lower end of the first limiting block 815 causes the first limiting block 815 to be pressed into the first limiting groove 813, and the first return spring 814 is compressed until the first limiting block 815 below pops out of the limiting opening 819. At this time, the support block 812 below contacts the ground instead of the roller 803, playing a supporting and fixing role. When canceling the fixation, press the second limiting block 818 until the second limiting block 818 is no longer restricted by the limiting opening 819, thereby achieving a reset effect and realizing the switching between the moving state and the fixed state of the overall teaching cart.

[0029] The above embodiment discloses a surgical teaching cart that can be stably fixed, wherein when the medical staff needs to move the teaching cart, the second limit block 818 is pressed until the second limit block 818 is no longer restricted by the limit opening 819, at which time the first limit block 815 is clamped in the limit sleeve 8110, and the support block 812 is inside the support shell 802. At this time, the second return spring 817 is compressed, and the second limit block 818 is located inside the support shell 802. When the teaching cart needs to be firmly fixed, the protrusion 811 is stepped on, and the inclined surface at the lower end of the first limit block 815 causes the first limit block 815 to be pressed into the first limit groove 813, and the first limit spring 814 is compressed until the first limit block 815 below pops out of the limit opening 819. At this time, the support block 812 below replaces the roller 803 to contact the ground, playing a supporting role. It has a supporting and fixing function. When teaching, the camera angle of the camera 605 can be freely adjusted through the camera angle adjustment mechanism 6, so that the surgical process can be displayed more comprehensively, so that the medical staff in training can learn the details of the surgery from any angle. The control rod 10 can prevent the operator from directly holding the camera 605 to adjust the camera angle when adjusting the camera angle, thereby causing damage to the camera 605. When the camera angle adjustment mechanism 6 is moved, the center of the entire teaching cart will be offset. At this time, the telescopic fence 701 is stretched to make the slider 704 slide inside the L-shaped groove 9 until the slider 704 slides to the bottom of the L-shaped groove 9 and is clamped in the shorter side of the L-shaped groove 9. At this time, the support rod 702 forms a stable triangular structure with the outer shell 1 and the telescopic fence 701, which can play a supporting role when the teaching cart topples over.
