[0021] After use, the operator removes the cover plate 122 from the slot seat 121 to completely open the connection sleeve 12, avoiding cleaning dead corners and facilitating cleaning of the equipment. In the design of this patent, multiple first electric push rods 3 jointly push the upper frame 1 and the lower frame 2 to increase the overall torque, and also make the force output more uniform, avoiding excessive local stress and causing the equipment to deviate.

[0022] As an improved specific implementation, a positioning notch 124 for positioning the cover plate 122 is provided at the top of the through slot 123 .

[0023] By setting the positioning notch 124 , during installation, the cover plate 122 is first positioned to facilitate subsequent fixing and assembly.

[0024] As an improved specific embodiment, the connecting assembly 4 includes a connecting rod 41, a connecting column 42 and a locking nut 43. A threaded hole 44 is opened on the upper frame 1 and the lower frame 2. A first stud 45 is provided at the bottom of the connecting column 42. The first stud 45 is threadedly connected to the threaded hole 44. An external thread is provided on the upper part of the connecting column 42. The locking nut 43 is threadedly connected to the external thread. The connecting rod 41 is connected to the side wall of the connecting column 42.

[0025] During installation, according to the position given by the computer, the doctor threadably connects the first stud 45 with the corresponding threaded hole 44. The connecting rod 41 can be inserted into the connecting column 42 through the pin hole, or it can be directly welded to the connecting column 42.

[0026] As an improved specific embodiment, a connecting mechanism 5 is arranged between the first electric push rod 3 and the upper frame 1 or the lower frame 2, and the connecting mechanism 5 includes a connecting seat 51, a first connecting ring 52, a bolt 54, a connecting nut 55 and two second connecting rings 53. The first connecting ring 52 is fixed to one end of the connecting seat 51, and a second stud 56 is arranged at the other end of the connecting seat 51. The second stud 56 is threadedly connected to the threaded hole 44. The two second connecting rings 53 are respectively fixed at both ends of the first electric push rod 3. The bolt 54 passes through the first connecting ring 52 and the second connecting ring 53 and is connected to the connecting nut 55 to connect the first electric push rod 3 to the upper frame 1 or the lower frame 2.

[0027] During installation, connect the second stud 56 to the threaded hole 44. Pay attention to whether the angle of the second connecting ring 53 conforms to the computer planning when the connection is completed. After the connection is completed, the second stud 56 can also be further fixed with a nut, so that the connecting seat 51 is not easily displaced. After installing the connecting seat 51 on the upper frame 1 and the lower frame 2, align the second connecting rings 53 at both ends of the first electric push rod 3 with the corresponding first connecting rings 52, and then tighten with bolts 54 and connecting nuts 55 to complete the installation. By connecting the upper frame 1, the lower frame 2 and the first electric push rod 3 in the above manner, it is convenient to adjust the angle of the first connecting ring 52 and the second connecting ring 53, so that the first electric push rod 3 can move according to the preset angle.

The patient can adjust the position of sitting, lying or other angles through the flip mechanism 64 according to the fracture situation and surgical needs, so as to facilitate medical staff to perform surgery. Before the operation, the medical staff places the lower frame 2 between the fixed plate 71 and the movable plate 72, and then passes the bolts through the connecting holes 74 on the fixed plate 71 and the movable plate 72 and the threaded bolts on the lower frame, and then tightens the bolts to clamp the lower frame 2 between the fixed plate 71 and the movable plate 72. The connecting holes 74 can cooperate with the threaded holes to position and support the lower frame 2, so that the installation of the lower frame 2 is more secure.
