[0002] During neurosurgery, a restraint is required to fix the patient's limbs. Generally, a strap is used. During limb fixation surgery, multiple straps are generally used for fixation. The distance between the straps is generally fixed, resulting in the straps blocking the patient's surgical site during fixation, which will affect the progress of the surgery. To solve this problem, we proposed a restraint. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1: Reference Figure 1-3The cam 6 is fixed on the operating table by bolts, and the base plate 1 is fixedly connected with a slide bar 6. Both ends of the slide bar 6 are penetrated by a moving block 4, and the two moving blocks 4 are fixedly connected with a connecting ring 2. An annular airbag 3 is fixedly connected to the two connecting rings 2. The inner ring wall of the annular airbag 3 is provided with an anti-slip groove. The annular airbag 3 is inflated and deflated by an inflation and deflation mechanism. The two moving blocks 4 are hinged with an articulated rod 8, and the two articulated rods 8 are hinged with a slider 9. The slider 9 moves by the moving mechanism, and the movement of the moving mechanism adjusts the position of the slider 9 so that when the slider 9 moves, the inclination angle of the articulated rod 8 is adjusted, thereby adjusting the position of the two sliders 4 on the slide bar 6 and the distance between the two connecting rings 2. It can be adjusted according to the area of ​​the operation, thereby avoiding blocking the surgical part when fixing, which is beneficial to the operation.

[0019] The inflation and deflation mechanism includes an air outlet valve 5, which is connected to the annular airbag 3, and the annular airbag 3 is connected to an air inlet valve 17. A micro air pump 12 is fixedly connected to the base plate 1, and a connecting pipe 10 is connected to the micro air pump 12. A connecting sleeve 11 is connected to the connecting pipe 10, and the connecting sleeve 11 can be threadedly connected to the air inlet valve 17. The micro air pump 12 is used for inflation, so that the annular airbag 3 is expanded and the limb part is clamped. When it needs to be loosened, the air outlet valve 5 can be opened, and the annular airbag 3 is fixed at the same time, which is conducive to uniform force during clamping.

[0020] The moving mechanism includes a slide groove 14, which is opened on the base plate 1. A slider 9 is slidably arranged in the slide groove 14. A threaded rod 13 is connected to the slider 9 through a thread. The threaded rod 13 is rotatably connected to the inner wall of the slide groove 14 through a bearing. By rotating the threaded rod 13, the position of the slider 9 in the slide groove 14 is adjusted, thereby adjusting the inclination angle of the hinged rod 8.

[0021] Example 2: In Example 1, when the limb is fixed, it is easy to accidentally rotate the threaded rod 13, causing the position of the fixing ring 2 to move. Figure 1-3 As another preferred embodiment of the present invention, on the basis of embodiment 1, a connecting cylinder 15 is fixedly connected to the base plate 1, a piston is provided in the connecting cylinder 15, and an abutting column 16 is fixedly connected to the piston. The abutting column 16 is located just above the threaded rod 13, and the connecting cylinder 15 is communicated with the annular airbag 3 through a conducting mechanism. During inflation, the gas in the annular airbag 3 enters the connecting cylinder 15, and the abutting column 16 moves, abutting the abutting column 16 on the threaded rod 13, fixing the threaded rod 13 and preventing the threaded rod 13 from being rotated by mistake. After the inflation, the air outlet valve 5 is opened, and the abutting column 16 cannot abut and apply pressure on the threaded rod 13, so as to drive the threaded rod 13 to rotate.

[0022] The conducting mechanism comprises a connecting hose 7, one end of which is communicated with the annular air bag 3 and the other end of which is communicated with the connecting cylinder 15.

[0023] The threaded rod 13 is provided with a knob for holding.

[0024] During the operation fixation, the threaded rod 13 is rotated to adjust the position of the sliding block 9 in the sliding groove 14, so that the sliding block 9 adjusts the inclination angle of the articulated rod 8 during the movement, thereby adjusting the position of the two sliding blocks 4 on the sliding rod 6 and the distance between the two connecting rings 2 to expose the part to be operated, and after the operation, the connecting sleeve 11 is screwed with the air inlet valve 17, the micro air pump 12 is inflated to expand the annular air bag 3 to clamp the limb part, and the gas in the annular air bag 3 enters the connecting cylinder 15 to move the abutting column 16 to abut against the threaded rod 13 to fix the threaded rod 13.

[0025] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
