In the above structure, when in use, firstly, the legs or arms of the patient are placed on the fixed block 101, then the driving rod 108 is rotated, the driving rod 108 drives the first screw rod 107 to rotate, the first screw rod 107 drives the first threaded pipe 106 to move, so that the two clamping plates 105 clamp the patient, then the second locking bolt 305 is rotated, so that the fixed sleeve 301 and the extension rod 303 are fixed, then the patient is moved to the operating table, then the clamping block 417 is clamped at the inner side of the clamping groove 102, so that the base 411 is supported on the operating table, then the rotating disc 413 is rotated, the rotating disc 413 drives the second threaded pipe 414 to move up and down, the second threaded pipe 414 drives the rotating head 415 to move up and down, so that the legs or arms of the patient are inclined upwards, the inclined angle is proper, then the second telescopic mechanism 42 is operated, so that the distance between the two bases 411 is fixed, and guarantee that two base 411 bottoms contact the operating table completely, then rotate support 205, make support 205 be located the second stabilizer bar 209 top, then rotate second screw 204, make support 205 descend, make the second stabilizer bar 209 peg graft in support 205 inboard, realized the function of fixed bolster 205 and the function that makes support 205 descend, can also rotate positive and negative lead screw 206, positive and negative lead screw 206 drives slider 207 and removes, slider 207 drives expansion frame 208 and removes, the function of strutting the muscle of pathological change department has been realized, alright this moment in order to have performed the operation.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
