[0037] The top of the sewage tank 4 is detachably installed with a box cover by bolts, and the top of the fresh water tank 3 is also provided with a box cover in the same way. When the box cover is opened, it is convenient to clean the inside of the fresh water tank 3 and the sewage tank 4 subsequently.

[0038] Four upright columns 7 are fixed on the top of the base 1, a lifting seat 8 is slidably installed between the four upright columns 7, a vertical threaded rod 9 is fixed at the bottom of the lifting seat 8, a threaded pipe 10 is threadedly sleeved at the bottom of the vertical threaded rod 9, the bottom of the threaded pipe 10 is rotatably installed on the top surface of the base 1, a through hole is formed through the base 1, and the lower end of the vertical threaded rod 9 extends into the through hole; a transmission gear 12 is installed at the upper end of the threaded pipe 10, a first motor 11 is installed on the top surface of the base 1, a transmission gear 12 is installed on the driving shaft of the first motor 11, and the two transmission gears 12 are engaged and driven with each other;

[0039] The top surface of the lifting seat 8 is rotatably installed with a rotating seat 13. A swing arm assembly 14 is installed on the rotating seat 13. The front end of the swing arm assembly 14 is installed with a telescopic assembly 15. The telescopic assembly 15 is installed with corresponding spray pipes 16 and a sewage collection box 17. The spray pipe 16 is connected to the first water pump 5 through a water supply hose 18. The bottom of the sewage collection box 17 is provided with a sewage discharge port, and the sewage discharge port is connected to the second water pump 6 through a sewage discharge hose 19.

[0040] The first motor 11 drives two transmission gears 12 to mesh and drive each other; thereby controlling the rotation of the threaded pipe 10. Since the threaded pipe 10 is rotatably installed with the base 1 and the threaded pipe 10 is also threadedly installed with the vertical threaded rod 9, the top end of the vertical threaded rod 9 is fixed to the bottom surface of the lifting seat 8. Four slip rings 81 are installed around the lifting seat 8. The slip rings 81 are slidably sleeved and installed with the column 7. The lifting seat 8 is slidably installed with the column 7 through the slip rings 81 around it. When the threaded pipe 10 rotates relative to the base 1, the vertical threaded rod 9 and the lifting seat 8 can be controlled to lift relative to the base 1 at the same time, so as to adjust the heights of the rotating seat 13, the swing arm assembly 14, the telescopic assembly 15, the spray pipe 16 and the sewage collection box 17 at the same time, so as to conveniently adjust the working height during the flushing operation according to needs and realize convenient wound flushing.

[0041] Further, a second motor 131 is installed on the top surface of the lifting seat 8. The drive shaft of the second motor 131 is installed with a bevel gear 132. The top surface of the rotating seat 13 is installed with a bevel gear ring 133. The bevel gear 132 meshes and drives with the bevel gear ring 133.

[0042] The second motor 131 drives the bevel gear 132 to mesh and drive with the bevel gear ring 133, and then controls the rotating seat 13 and the upper swing arm assembly 14, telescopic assembly 15, spray pipe 16 and sewage collection box 17 to rotate and adjust the angle at the same time.

[0043] Further, the swing arm assembly 14 includes a fixed arm 141, a first swing arm 142, and a second swing arm 143. The fixed arm 141 is fixed on the top wall of the rotating seat 13. A servo motor assembly 144 for driving the first swing arm 142 is installed on the fixed arm 141. A servo motor assembly 144 for driving the second swing arm 143 is installed on the first swing arm 142.

[0044] The servo motor assembly 144 includes a stepper motor 145 and a rotating shaft 146. The drive shaft of the stepper motor 145 is installed with a worm 147. A worm gear 148 is installed on the rotating shaft 146. The worm 147 meshes and drives with the worm gear 148.

[0045] Such as Figure 4As shown in the figure, taking the servo assembly 144 located between the first swing arm 142 and the second swing arm 143 as an example: The rotating shaft 146 in the servo assembly 144 located between the first swing arm 142 and the second swing arm 143 is fixedly installed with the second swing arm 143, and is also rotatably installed with the first swing arm 142. When the stepping motor 145 is installed on the first swing arm 142 and the stepping motor 145 drives the worm 147 to rotate, the rotation angle of the worm gear 148, the rotating shaft 146 and the second swing arm 143 can be controlled.

[0046] In addition, taking the servo assembly 144 located between the first swing arm 142 and the fixed arm 141 as an example, the difference is that: the rotating shaft 146 is fixed to the lower end of the first swing arm 142 and is rotatably installed with the fixed arm 141 at the same time. The stepping motor 145 is installed on the fixed arm 141 or the rotating base 13. Then, when the stepping motor 145 drives the worm 147 to rotate, the rotation angle of the worm gear 148, the rotating shaft 146, the first swing arm 142 and the second swing arm 143 can be controlled simultaneously.

[0047] Through the movement of the swing arm assembly 14, the positions and angles of the telescopic assembly 15, the nozzle 16 and the sewage collection box 17 relative to the wound of the patient's limbs can be driven and adjusted, which is convenient for flushing the surgical wound.

[0048] Furthermore, the telescopic assembly 15 includes a sliding arm 151 slidably installed at the front end of the second swing arm 143. The second swing arm 143 is provided with a chute, and the sliding arm 151 is matched with the chute. A third motor 152 is installed at the front end of the second swing arm 143. A first lead screw 153 is installed on the drive shaft of the third motor 152. The first lead screw 153 is threadedly installed with the middle part of the sliding arm 151. The two ends of the sliding arm 151 extend to the outside of the chute and are both installed with U-shaped racks 154. Brackets 155 are symmetrically installed on the upper and lower sides at the front end of the second swing arm 143, and a rotating rod 156 parallel to the sliding arm 151 is rotatably installed on the bracket 155. Driven gears 157 and upper cantilever 158 are installed at both ends of the rotating rod 156 on the upper side, and driven gears 157 and lower cantilever 159 are installed at both ends of the rotating rod 156 on the lower side. The driven gears 157 are respectively meshed and driven with the U-shaped racks 154 on the same side. There are two upper cantilevers 158, and the rear ends of the two upper cantilevers 158 are respectively fixed to both ends of the rotating rod 156 on the upper side. There are two lower cantilevers 159, and the rear ends of the two lower cantilevers 159 are respectively fixed to both ends of the rotating rod 156 on the lower side. The front ends of the two upper cantilevers 158 are both fixed to the end of the nozzle 16. A plurality of nozzles 161 facing the sewage collection box 17 are installed on the nozzle 16. The front ends of the two lower cantilevers 159 are both fixed to the end of the sewage collection box 17.

[0049] When flushing the wounds on the patient's limbs, the telescopic assembly 15 is used to control the spray pipe 16 and the sewage collection box 17 to approach each other, so that the spray pipe 16 and the sewage collection box 17 are respectively located above and below the patient's limbs. The spray pipe 16 can use the spray head 161 to spray the flushing liquid, and the sewage generated during flushing is collected by the sewage collection box 17 and pumped into the sewage tank 4 through the sewage discharge hose 19 and the second water pump 6 for storage, and can be centrally dumped later.

[0050] The telescopic assembly 15 uses the third motor 152 to drive the first lead screw 153. At this time, the sliding arm 151 can be controlled to slide relative to the front end of the second swing arm 143. When sliding, the U-shaped racks 154 on both sides are driven to move. The U-shaped racks 154 engage and drive the driven gears 157 above and below, so that the rotating rods 156 above and below rotate in opposite directions. For example, the rotating rod 156 above rotates counterclockwise, and the rotating rod 156 below rotates clockwise. At this time, the spray pipe 16 and the sewage collection box 17 approach each other. At this time, the spray pipe 16 can approach the patient's limbs, such as approaching and flushing the wound on the leg. After flushing the wound, control the spray pipe 16 and the sewage collection box 17 to move away from each other. At this time, the position of the wound on the patient's leg can be left.

[0051] When considering flushing the wounds on the patient's limbs, such as the wound on the leg, in order to facilitate the patient's leg to maintain a stable state, further, an arc-shaped mesh plate 171 is fixed on the top surface of the sewage collection box 17, and a plurality of mesh holes are penetrated through the arc-shaped mesh plate 171. The arc-shaped mesh plate 171 can support the leg, facilitating subsequent wound flushing.

[0052] In order to improve the discharge efficiency of the sewage in the sewage collection box 17 and clean the surface of the arc-shaped mesh plate 171, further, a cleaning brush assembly is installed in the sewage collection box 17. The cleaning brush assembly includes a cleaning brush 20 slidably arranged in the sewage collection box 17. Two second lead screws 21 are symmetrically and threadedly installed on both sides of the cleaning brush 20. One end of the second lead screws 21 on the same side is driven by a pulley 23 and a belt. One end of one of the second lead screws 21 is connected to the drive shaft of the fourth motor 22, and the fourth motor 22 is installed outside the sewage collection box 17.

[0053] Further, the cleaning brush 20 includes a frame 201. A single-piece brush strip 202 is fixed on the lower side of the frame 201, and a double-piece arc-shaped brush strip 203 is fixed on the upper side of the frame 201. The double-piece arc-shaped brush strip 203 includes an upper arc-shaped brush strip and a lower arc-shaped brush strip. The upper arc-shaped brush strip is in frictional contact with the upper surface of the arc-shaped mesh plate 171, and the lower arc-shaped brush strip is in frictional contact with the lower surface of the arc-shaped mesh plate 171;

[0054] The bottom of the sewage collection box 17 is an arc-shaped plate body. The single-piece brush strip 202 is an arc-shaped structure, and the single-piece brush strip 202 is in frictional contact with the inner surface of the bottom of the sewage collection box 17.

[0055] The fourth motor 22 cooperates with the pulley 23 to drive the two second lead screws 21. At this time, the second lead screws 21 can control the movement of the cleaning brush 20 in the dirt collection box 17, so as to clean the upper and lower surfaces of the arc-shaped mesh plate 171 by using the double-piece arc-shaped brush strips 203, clean the bottom of the dirt collection box 17 by using the single-piece brush strip 202, and clean the side surface of the dirt collection box 17 by using the frame 201. By cleaning the inside of the dirt collection box 17 and the upper and lower surfaces of the arc-shaped mesh plate 171, it is possible to avoid the adsorption of stains such as blood during the flushing of the patient's wound, reduce residues, improve the internal cleanliness, and better disinfect and sterilize later.
