Embodiment 1
[0034] Such as Figure 1 to Figure 3 As shown, the present invention includes a rectangular support frame and slide bars:
[0035] The four corners of the rectangular support frame are provided with vertical threaded holes, the threaded through holes are internally threaded to connect the third screw rod 1, and the lower end of the third screw rod 1 is fixedly connected to the legs 2, and the rectangular support frame includes the first support connected end to end. Plate 3, the second support plate 4, the third support plate 5 and the fourth support plate 6, the first support plate 3 and the third support plate 5 all offer the first elongated through hole 7, the second support plate 4 and the second support plate The four support plates 6 all have second elongated through holes 8, wherein the upper end surfaces of the first support plate 3 and the third support plate 5 are fixedly connected with the lower end surfaces of the second support plate 4 and the fourth support plate 6...
Embodiment 2
[0038] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as Figure 4 As shown, the outer sides of the first elongated through hole 7 and the second elongated through hole 8 are provided with a scale line 20. This structural design is conducive to improving the size of the medical staff's control of the left and right or front and rear retraction areas during the operation. Save operation time; the upper end surfaces of the first slide bar 9, the second slide bar 10, the third slide bar 11 and the fourth slide bar 12 are all fixedly connected to the handle 21, and the handle 21 can adopt a C-shaped structure in this embodiment. Designed for quick movement of the slider.
Embodiment 3
[0040] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as Figure 5 As shown, the lower end of the leg 2 is fixedly connected to the suction cup 22. This structural design can quickly absorb the entire device on the operating bed through the suction cup 22 during use, effectively saving installation time and improving the efficiency of surgical preparation, especially for acute myocarditis or myocardial infarction. Symptoms, strive for rescue time for patients.
