[0020] When the present invention is in use, according to the angle of the patient's wound, the rotating disk 9 is rotated. The rotating disk 9 drives the middle pressing block 16 to rotate so that the angle of the middle pressing block 16 corresponds to that of the patient's wound. The middle pressing block 16 is pressed against the patient's wound through the support plate 1 and the rotating disk 9. The binding band 2 is wound around the patient's limb, and the binding band 2 is passed through the perforation and fixed on the round hair magic tape 4 through the barbed magic tape 3, so as to fix the support plate 1, the rotating disk 9, the middle pressing block 16, etc. on the patient's limb.

The plurality of side pressing blocks 19 perform multi-stage extrusion on the skin on both sides of the patient's wound towards the wound through the gauze 7, so that the wound is closed, which can effectively prevent the skin on both sides of the patient's wound from pulling on the wound site and improve the closing effect of the patient's wound. Moreover, the plurality of side pressing blocks 19 are extruded synchronously, which can effectively improve the extrusion stability of the side pressing blocks 19. Through the cooperation of the middle pressing block 16 and the side pressing blocks 19, the patient's wound is pressed and squeezed on both sides to promote the closure of the patient's wound and improve the hemostasis effect of the patient's wound.

[0021] Further, a lifting assembly for driving the middle pressing block 16 to slide along the rotating disk 9 is provided on the rotating disk 9, and a traction assembly for driving a plurality of sliding frames 18 on both sides of the middle pressing block 16 to move synchronously is also provided on the rotating disk 9. A driving housing 5 is detachably connected to the rotating disk 9, and a driving structure for driving the lifting assembly and the traction assembly to act is provided in the driving housing 5.

[0022] Further, the driving structure includes a driving motor 35 fixedly connected to the driving housing 5. The output end of the driving motor 35 is connected with a driving bevel gear set 34.

The traction assembly includes a driving frame 17 fixedly connected to the middle pressing block 16. A driving spline shaft 13 is rotatably connected to the driving frame 17, and a driven bevel gear set 23 is connected to the driving spline shaft 13.

The driven bevel gear set 23, the driving bevel gear set 34, and the lifting bevel gear set 33 all include a driving bevel gear, and a driven bevel gear is engaged with the driving bevel gear. The driving bevel gear is the input end, and the driven bevel gear is the output end.

[0023] When the traction assembly is in use, the drive motor 35 is started, and the drive motor 35 drives the drive bevel gear set 34 to rotate; the drive bevel gear set 34 drives the drive spline tube 31 to rotate, and the drive spline tube 31 drives the drive spline shaft 13 to rotate; the drive spline shaft 13 drives the worm to rotate through the driven bevel gear set 23, the worm drives the worm gear 24 to rotate, and the worm gear 24 further drives the following double crank 25 to rotate; through the cooperation of the worm and the worm gear 24, the transmission of the traction assembly is self-locked to improve the stability of the traction assembly.

[0024] Further, as Figure 5 shown, a double crank 25 is fixedly connected to the worm gear 24, and the central position of the double crank 25 is rotatably connected to the middle pressing block 16; support rods 22 are fixedly connected to both sides of the middle pressing block 16, and the sliding frame 18 is slidably connected to the support rods 22; a driven rod 27 is rotatably connected to the sliding frame 18 that is the farthest from the middle pressing block 16 among the plurality of sliding frames 18, and intermediate rods 26 are rotatably connected to the sliding frames 18 between the driven rod 27 and the double crank 25. The central position of the intermediate rod 26 is rotatably connected to the corresponding sliding frame 18, the double crank 25 is rotatably connected to the adjacent intermediate rod 26, the adjacent intermediate rods 26 are rotatably connected to each other, and the driven rod 27 is rotatably connected to the adjacent intermediate rod 26.

[0025] When the worm gear 24 rotates, the worm gear 24 drives the double crank 25 to rotate, and the double crank 25 drives the intermediate rod 26 to rotate. As Figure 5 shown, a pair of sliding frames 18 are respectively provided on both sides of the middle pressing block 16. At this time, the intermediate rod 26 drives the driven rod 27 to rotate; if the number of sliding frames 18 on both sides of the middle pressing block 16 is more than one pair, at this time, the intermediate rods 26 act on each other for transmission until the last intermediate rod 26 drives the driven rod 27 to rotate, so that the sliding frames 18 on both sides of the middle pressing block 16 slide synchronously along the support rods 22 on the middle pressing block 16, and the sliding frames 18 drive the side pressing blocks 19 to move synchronously to squeeze the skin on both sides of the wound, so as to close the wound.

[0026] Further, the lifting assembly includes a threaded column 15 rotatably connected to the drive frame 17, and the threaded column 15 is screwed to the rotating disc 9; a guide column 8 is fixedly connected to the middle pressing block 16, and the guide column 8 is slidably connected to the rotating disc 9; a lifting motor 32 is fixedly connected to the drive housing 5, and the output end of the lifting motor 32 is connected with a lifting bevel gear set 33; the output end of the lifting bevel gear set 33 is connected with a lifting spline shaft 30, and a spline groove for cooperating with the lifting spline shaft 30 is provided on the threaded column 15.

[0027] When the lifting assembly is in use, start the lifting motor 32. The lifting motor 32 drives the lifting bevel gear set 33 to act, and the lifting bevel gear set 33 drives the lifting spline shaft 30 to rotate. The lifting spline shaft 30 drives the threaded column 15 to rotate through the spline groove. Under the action of the rotating disk 9 and the guiding column 8, the threaded column 15 drives the driving frame 17 to move up and down. The driving frame 17 drives the middle pressing block 16 to slide along the rotating disk 9 through the guiding column 8, so as to realize the pressing and hemostasis of the patient's wound by the middle pressing block 16.

[0028] Further, a plurality of positioning columns 29 are fixedly connected to the driving housing 5, and a plurality of positioning holes 12 matched with the plurality of positioning columns 29 are arranged on the rotating disk 9. The connection between the driving housing 5 and the rotating disk 9 is realized through the cooperation of the positioning columns 29 and the positioning holes 12. A holding groove 28 convenient for the user to hold is arranged on the driving housing 5.

[0029] Further, as Figure 4 shown, a sliding rod 20 is fixedly connected to the side pressing block 19, and the sliding rod 20 is slidably connected with the sliding frame 18. Connecting rods 21 are rotatably connected to both ends of the plurality of side pressing blocks 19, and the other ends of the connecting rods 21 are rotatably connected to the middle pressing block 16. When the side pressing block 19 moves with the sliding frame 18, under the action of the connecting rod 21, the side pressing block 19 slides along the sliding frame 18 through the sliding rod 20. Since the plurality of sliding frames 18 move synchronously under the action of the middle rod 26 and the driven rod 27, the moving distances of the plurality of sliding frames 18 increase in sequence, that is, the farther the sliding frame 18 is from the middle pressing block 16, the farther its moving distance is. At the same time, under the action of the connecting rod 21, the moving distances of the side pressing blocks 19 increase in sequence, so that the connecting lines of the plurality of side pressing blocks 19 form a structure similar to an arc, and the side pressing blocks 19 press the patient's skin step by step, so as to improve the pressing effect of the side pressing blocks 19 on the patient's skin and improve the closing effect of the patient's wound.

[0030] Further, as Figure 2 shown, a fixing ring 6 is fixedly connected to the support plate 1, and plugging grooves are evenly distributed on the fixing ring 6 along the circumference. A sleeve is fixedly connected to the rotating disk 9, and a sliding cylinder 10 is slidably connected to the sleeve. A top spring matched with the sliding cylinder 10 is arranged in the sleeve. A plug 11 matched with the plugging groove is fixedly connected to the sliding cylinder 10, and a lever 14 is fixedly connected to the plug 11.

[0031] When the rotating disk 9 needs to rotate, the plug 11 is pulled by the lever 14. The plug 11 drives the sliding cylinder 10 to slide along the sleeve and presses the top spring, so that the plug 11 is separated from the plugging groove. Rotate the rotating disk 9. When the angle of the middle pressing block 16 is aligned with the angle of the wound, stop rotating the rotating disk 9 and release the lever 14. The sliding cylinder 10 slides along the sleeve under the action of the top spring, and the sliding cylinder 10 drives the plug 11 to cooperate with the plugging groove on the fixing ring 6, so as to realize the limit fixation of the rotating disk 9 and improve the stability of the rotating disk 9.

[0032] As Figures 1 to 8 shown, the working process of the present invention will be specifically explained in detail below.

[0033] When the present invention is in use, the rotary disk 9 is rotated according to the angle of the patient's wound; specifically, the insertion block 11 is pulled by the lever 14, and the insertion block 11 drives the sliding cylinder 10 to slide along the sleeve and squeeze the top spring, so that the insertion block 11 is separated from the insertion slot; the rotary disk 9 is rotated, and the rotary disk 9 drives the middle pressing block 16 to rotate. When the angle of the middle pressing block 16 is aligned with the angle of the wound, the rotation of the rotary disk 9 is stopped, the lever 14 is released, and the sliding cylinder 10 slides along the sleeve under the action of the top spring. The sliding cylinder 10 drives the insertion block 11 to cooperate with the insertion slot on the fixed ring 6 to realize the limit fixation of the rotary disk 9.

[0034] The middle pressing block 16 is pressed against the patient's wound through the support plate 1 and the rotary disk 9, so that the binding band 2 bypasses the patient's limb, and the binding band 2 is passed through the perforation and fixed on the round hair magic tape 4 through the barbed magic tape 3, so as to fix the support plate 1, the rotary disk 9, the middle pressing block 16, etc. on the patient's limb.

[0035] The lifting spline shaft 30 is installed on the spline groove of the threaded column 15, and the driving spline cylinder 31 is installed on the driving spline shaft 13, so that the positioning column 29 on the driving housing 5 is aligned and installed with the positioning hole 12 on the rotary disk 9; the lifting motor 32 is started, and the lifting motor 32 drives the lifting bevel gear set 33 to act. The lifting bevel gear set 33 drives the lifting spline shaft 30 to rotate; the lifting spline shaft 30 drives the threaded column 15 to rotate through the spline groove. Under the action of the rotary disk 9 and the guide post 8, the threaded column 15 drives the driving frame 17 to move up and down, and the driving frame 17 drives the middle pressing block 16 to slide along the rotary disk 9 through the guide post 8, so as to realize the pressing and hemostasis of the middle pressing block 16 on the patient's wound.

[0036] At the same time, the driving motor 35 is started, and the driving motor 35 drives the driving bevel gear set 34 to rotate; the driving bevel gear set 34 drives the driving spline cylinder 31 to rotate, and the driving spline cylinder 31 drives the driving spline shaft 13 to rotate; the driving spline shaft 13 drives the worm to rotate through the driven bevel gear set 23, the worm drives the worm gear 24 to rotate, and the worm gear 24 further drives the double crank 25 to rotate; the double crank 25 drives the intermediate rod 26 to rotate. As Figure 5 shown, a pair of sliding frames 18 are respectively arranged on both sides of the middle pressing block 16. At this time, the intermediate rod 26 drives the driven rod 27 to rotate, and the intermediate rod 26 and the driven rod 27 drive the corresponding sliding frames 18 to slide along the support rod 22; if more than a pair of sliding frames 18 are respectively arranged on both sides of the middle pressing block 16, at this time, the intermediate rods 26 act on each other and drive, until the last intermediate rod 26 drives the driven rod 27 to rotate, so that the sliding frames 18 on both sides of the middle pressing block 16 slide synchronously along the support rod 22 on the middle pressing block 16.

[0037] The sliding carriage 18 drives the side extrusion block 19 to move synchronously. Under the action of the connecting rod 21, the side extrusion block 19 slides along the sliding carriage 18 through the sliding rod 20. Since multiple sliding carriages 18 move synchronously under the action of the intermediate rod 26 and the driven rod 27, the moving distances of the multiple sliding carriages 18 increase successively, that is, the farther the sliding carriage 18 is from the middle pressing block 16, the farther its moving distance is. At the same time, under the action of the connecting rod 21, the moving distances of the side extrusion blocks 19 increase successively, and the connecting lines of the multiple side extrusion blocks 19 form a structure similar to an arc, so that the side extrusion blocks 19 gradually extrude the patient's skin to improve the extrusion effect of the side extrusion blocks 19 on the patient's skin and the closing effect of the patient's wound.

[0038] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: 1. When the present invention is in use, according to the angle of the patient's wound, the rotary disk 9 is rotated. The rotary disk 9 drives the middle pressing block 16 to rotate so that the angle of the middle pressing block 16 corresponds to the angle of the patient's wound. In addition, the middle pressing block 16 presses the patient's wound to stop bleeding, and the side extrusion blocks 19 on the sliding carriage 18 extrude the skin on both sides of the patient's wound towards the wound, so that the wound is closed, which can effectively avoid the skin on both sides of the patient's wound from pulling the wound area and improve the closing effect of the patient's wound. Through the cooperation of the middle pressing block 16 and the side extrusion blocks 19, the patient's wound is pressed and extruded on both sides to promote the closing of the patient's wound and improve the hemostasis effect of the patient's wound.

[0039] 2. When the present invention is in use, through the cooperation of the double - acting crank 25, the intermediate rod 26 and the driven rod 27, multiple sliding carriages 18 are driven to slide synchronously along the support rod 22 on the middle pressing block 16. The moving distances of the multiple sliding carriages 18 increase successively, that is, the farther the sliding carriage 18 is from the middle pressing block 16, the farther its moving distance is. At the same time, under the action of the connecting rod 21, the moving distances of the side extrusion blocks 19 increase successively, and the connecting lines of the multiple side extrusion blocks 19 form a structure similar to an arc, so that the side extrusion blocks 19 gradually extrude the patient's skin to improve the extrusion effect of the side extrusion blocks 19 on the patient's skin and the closing effect of the patient's wound.
