The medical staff first selects the appropriate first positioning plate 6 and the second positioning plate 7, inserts the first positioning plate 6 on the rotating support plate 16, the medical staff rotates the rotating disk of the first fixed worm 302, and the first fixed worm 302 drives the The first fixed worm wheel rotates, the first fixed worm wheel drives the first fixed screw 303 to rotate, the first fixed screw 303 drives the first fixed slider 304 to slide on the chute of the fixed plate 301, and the first fixed slider 304 drives the first fixed slider 304. A fixed link 305 moves horizontally, and the first fixed link 305 drives the driven link 306 to move. At the same time, when the driven link 306 moves, the driven link 306 rotates on the first fixed link 305, and the first fixed link 306 moves. After the adjustment of the fixed link 305 is completed, the position of the driven link 306 is adjusted by the adjustment and compression link mechanism, so that the first pressing column 307 can press the first positioning plate 6 into a suitable arc; The second positioning plate 7 is inserted into the first positioning plate 6, and then the depth adjustment screw is rotated. The depth adjustment screw drives the pressing plate 20 to move, and the pressing plate 20 drives the second positioning plate 7 to slide along the limit guide slideway. According to the scale line, the depth of the incision of the knife edge into the patient's abdomen can be selected. After pressing the second positioning plate 7 to a suitable position, the second positioning plate 7 is fixed by the pressing and rotating mechanism, so that the second positioning plate 7 is basically the same as the first positioning plate 6. parallel.

After the adjustment of the first positioning plate 6 and the second positioning plate 7 is completed, the medical staff holds the rotating support plate 16 to insert the first plug from the lower end into the first plug hole of the first plug connector, and then tighten the bolt 15 Screw into the threaded holes of the first plug connector and the first plug to fix the rotating support plate 16 on the angle adjustment plate 14; the medical staff rotates the angle adjustment worm, the angle adjustment worm drives the angle adjustment worm wheel 13 to rotate, and the angle adjustment worm wheel 13 drives The angle adjustment plate 14 rotates, and the angle adjustment plate 14 drives the first positioning plate 6 and the second positioning plate 7 to move; the medical staff rotates the rotating plate of the lifting screw 12, and the lifting screw 12 rotates to drive the lifting column to slide down along the guide column, After sliding to an appropriate position, the medical staff can adjust the link mechanism and the adjustment pressing link mechanism to adjust the first positioning plate 6, and use the pressing and rotating mechanism to adjust the second positioning plate 7, so that the first positioning plate 6 is basically the same as the one. The patient's abdomen is fitted; then the scalpel is clamped with the blade clip 9, and the blade clip 9 is then slid along the cutting slide 8 to perform surgery on the patient's abdomen; when using the present invention, the first positioning plate 6 can be Adjust with the second positioning plate 7, so that the first positioning plate 6 basically fits better with the patient's abdomen; after the operation is completed on the patient, the medical staff quickly turns down the stabilizing bolt, and then the upper support column 101 and the The device connected to the upper support column 101 is removed as a whole, which is convenient for the doctor to perform the next treatment on the patient.
