When the invention is used, the support frame 2 is not arranged on the bottom plate 1, and a plurality of groups of front massage plates 17 and rear massage plates 14 are in an initial state of sequentially opening from right to left; pulling the hook 35 backwards to enable the hook 35 to be separated from the retaining ring 34, and pulling up the arc-shaped cover plate 11 and the limiting plate 12; the bottom plate 1 is placed on the lower side of the puncture limb of the patient, the front end and the rear end of the support frame 2 are respectively inserted into the mounting grooves, the lower end of the support frame 2 extrudes the positioning blocks 20 to enable the two positioning blocks 20 to move back and forth, the connecting rope 21 becomes loose at the moment, and after the positioning blocks 20 completely slide into the sliding grooves 19, the positioning blocks 20 are inserted into the positioning grooves 18 under the action of the springs, so that the support frame 2 is fixed on the bottom plate 1;

observing the positions of the pressing pad 31 and the puncture position, so that the pressing pad 31 is positioned right above the inner puncture opening, the arc-shaped cover plate 11 is buckled on the bottom plate 1, and at the moment, the limiting plate 12 is positioned at the upper side of the knee of the patient and is used for fixing and limiting the knee of the patient, thereby effectively preventing the puncture side limb of the patient from curling when the puncture point of the patient is compressed, and influencing the compression hemostasis effect;

the adjusting bolt 5 is rotated, the adjusting screw rod 5 drives the pressing rod 4 to move downwards relative to the support frame 2, meanwhile, the lower end of the adjusting screw rod 5 drives the reel 23 to rotate, the reel 23 pulls the slider 25 to move downwards through the pull rope 24, and further the slider 25 drives the polygonal sleeve 8 to move downwards, because the fine adjustment screw rod 10 is rotationally connected with the polygonal sleeve 8, the polygonal sleeve 8 drives the pressing pad 31 to move downwards through the fine adjustment screw rod 10 and the sliding sleeve 9, so that the pressing pad 31 moves downwards relative to the pressing rod 4 when moving downwards, namely, the downward moving speed of the pressing plate 6 is less than the downward moving speed of the pressing pad 31, when the lower surface of the pressing plate 6 is attached to the thigh skin of a patient, the adjusting screw rod 5 stops rotating, the pressing pad 31 tightly extrudes an inner puncture point, the stop block 33 is inserted into the tooth groove of the outer gear ring 32 under the action of the spring, and the puncture part is effectively prevented from pushing the pressing, so that the reel 23 is reversely rotated to cause a compression failure;

when the dorsal artery of the foot is touched, the pressing force of the pressing pad 31 on the puncture position can keep hemostasis and ensure the blood supply level, when the pressing force of the pressing pad 31 on the puncture point needs to be reduced, the fine adjustment screw rod 10 is rotated, the polygonal sleeve 8 is static, the sliding sleeve 9 drives the pressing pad 31 to move upwards under the matching of the guide rod 26 and the guide groove, the dorsal artery of the foot is touched, the fine adjustment screw rod 10 stops rotating after the dorsal artery is normal, at the moment, the pressing rod 4 and the support rod form a cross shape, the puncture position can be effectively pressed and stopped, and the bleeding condition caused by looseness and displacement of the pressing pad 31 is prevented;

after the hemostasis is finished, the knob 22 is rotated, the two connecting ropes 21 are simultaneously wound on the knob 22 and pull the positioning block 20 to slide into the sliding groove 19, the support frame 2 is taken down from the bottom plate 1, the knob 22 is loosened, and the positioning block 20 and the connecting ropes 21 are reset.

When the crus of the patient needs to be massaged, so as to prevent thrombus, the motor 28 is started, the motor 28 drives the rotating shaft 15 to rotate from front to back, taking the rightmost cam 16 as an example, the rightmost cam 16 rotates backwards and gradually presses the rightmost rear massage plate 14, the front end of the rightmost rear massage plate 14 swings downwards and the rear end of the rightmost rear massage plate swings upwards and presses the torsion spring, the front end of the rightmost cam 16 presses the rear side of the inverted Z-shaped rod 29, the rear side of the inverted Z-shaped rod 29 swings forwards and the front side of the inverted Z-shaped rod 29 drives the upper end of the front massage plate 17 to swing backwards to form a white hole, so that when the rightmost cam 16 rotates, the corresponding front massage plate 17 swings back to the rear massage plate 14, namely the front cam 16 on the leftmost side gradually breaks away from pressing the corresponding front massage plate 17 and rear massage plate 14, namely the front massage plate 17 and the rear massage plate 14 on the leftmost side swing relatively under the action of the torsion spring to realize pressing of the crus of, therefore, when the rotating shaft 15 rotates for one circle, each group of the front massage plates 17 and the back massage plates 14 are opened and clamped and extruded once, and the multiple groups of the front massage plates 17 and the back massage plates 14 are opened from right to left in sequence and then closed in sequence, along with the continuous operation of the motor 28, the multiple groups of the front massage plates 17 and the back massage plates 14 simulate manual continuous circular massage on the lower legs of patients from ankles to knee directions, so that the blood circulation is promoted, the occurrence of thrombus is avoided, and the massage effect is improved.

Therefore, the positioning and compressing device used after the cardiac radiofrequency ablation can effectively solve the problems that the hemostasis and compressing effect of the femoral artery puncture point is poor and thrombus is easy to appear on the limb at the puncture side.
