DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3The utility model provides a technical solution: an auxiliary mechanical support for medical orthopedic surgery, comprising two support rods 1, the upper ends of the two support rods 1 are fixedly connected to a support plate 2, a fixing frame 3 is slidably connected to the support plate 2, the fixing frame 3 is penetrated with two first threaded holes 4, a first threaded rod 5 is threadedly connected in the two first threaded holes 4, the lower end of the first threaded rod 5 penetrates and extends to the outside of the fixing frame 3 and is rotatably connected to a support ring 6 through a bearing, a second threaded hole 7 is penetrated on the hole wall of the first threaded hole 4, a second threaded rod 8 is threadedly connected in the second threaded hole 7, one end of the second threaded rod 8 penetrates and extends to the outside of the fixing frame 3 and is rotatably connected to a positioning rod 9 through a bearing, a positioning hole 10 is penetrated on the fixing frame 3 corresponding to the position of the positioning rod 9, and the positioning rod 9 is inserted into the positioning hole 10.

[0017] Among them, a sliding groove 11 is opened at the position of the support plate 2 corresponding to the first threaded rod 5, and the first threaded rod 5 is slidably connected in the sliding groove 11. The sliding rod 11 can provide space for the first threaded rod 5 to move, thereby avoiding affecting the fixed frame 3 to drive the first threaded rod 5 and the support ring 6 to move.

[0018] One end of the second threaded rod 8 outside the fixing frame 3 is fixedly connected with a rotating handle 12 , and the second threaded rod 8 can be rotated by rotating the handle 12 .

[0019] A third threaded rod 13 is fixedly connected to the lower surface of one of the support rods 1 , and the support rod 1 is installed on the operating table through the third threaded rod 13 .

[0020] Among them, the positioning rod 9 is set in an L shape, and the end of the positioning rod 9 away from the second threaded rod 8 is slidably connected in the positioning hole 10. Under the limitation of the positioning hole 10, the positioning rod 9 can only move parallely and be inserted into the installation frame 3 to abut against the support plate 2.

[0021] Specifically, when using the utility model, the support rod 1 is first installed on the operating bed through the third threaded rod 13, and the other support rod 1 supports the support plate 2 by abutting against the operating bed. At this time, the fixed frame 3 can be moved on the support plate 2 and the position of the support ring 6 can be adjusted. Then the first threaded rod 5 can be rotated, and the first threaded rod 5 rises in the first threaded rod 4 and drives the support ring 6 to adjust the height. After that, the second threaded rod 8 can be rotated by turning the handle 12, and the second threaded rod 8 moves in the second threaded hole 7 until it abuts against the first threaded rod 5, thereby fixing the first threaded rod 5 and the support ring 6. At the same time, the second threaded rod 8 will drive the positioning rod 9 to move synchronously and be inserted into the fixing frame 3 through the positioning hole 10, so that the positioning rod 9 abuts against the outer wall of the support plate 2 to fix the fixing frame 3 and the support ring 6, thereby making the overall adjustment and installation of the equipment relatively simple and convenient.
