[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

In order to facilitate the adjustment of the height of the liquid storage device 21, the liquid hanging rod assembly also includes a lifting mechanism 3 and a detection mechanism 4, the lifting mechanism 3 including a lifting drive member 31, the movable end of the lifting drive member 31 is transmission-connected to the supporting rod 11, and the lifting drive member 31 is used to drive the supporting rod 11 to rise and fall. When in use, the potential energy of the liquid storage device 21 is converted into the kinetic energy of the flushing liquid. Therefore, the height of the liquid storage device 21 can determine the flow rate of the flushing liquid sprayed out from the nozzle. The higher the height of the liquid storage device 21, the greater the kinetic energy obtained by the flushing liquid, so that the flow rate is higher; conversely, the flow rate is lower. Therefore, when in use, the user sets the flow rate of the flushing liquid according to needs, and the system calculates the height that the liquid storage device 21 needs to reach according to the formula mgH=1 / 2mv2 for converting potential energy into kinetic energy, and then the lifting drive 31 drives the support rod 11 to drive the liquid storage device 21 to lift and lower. The detection mechanism 4 can detect the displacement of the support rod to ensure that the liquid storage device 21 can accurately reach the set height.

[0025] The beneficial effects of the embodiments of the present invention are as follows:

[0026] The liquid hanging rod assembly of the embodiment of the present invention is provided with a supporting mechanism 1, a liquid supply assembly 2 and a lifting mechanism 3, wherein the supporting mechanism 1 includes a supporting rod 11 and a hanging rack 12, the hanging rack 12 is connected to the supporting rod 11, the liquid supply assembly 2 includes a liquid storage device 21, the liquid storage device 21 is hung on the hanging rack 12, and the lifting mechanism 3 includes a lifting drive 31, the lifting drive 31 can drive the supporting rod 11 to rise and fall according to the set flow rate, and the detection mechanism can detect the displacement of the supporting rod. When in use, after inputting the set flow rate, the lifting drive can drive the supporting rod according to the relationship between the flow rate and the height of the liquid storage device to adjust the height of the liquid storage device hung on the supporting rod, the detection mechanism can ensure the displacement accuracy of the supporting rod, and when the height of the liquid storage device needs to be adjusted to adjust the flow rate of the flushing liquid, the lifting drive 31 drives the supporting rod 11 to rise and fall to a certain position, so as to achieve adjustment. This adjustment structure is faster and more precise, thereby improving the efficiency of surgery.

[0027] See also Figure 2 The detection mechanism 4 includes a weight detection member 41 and / or a distance detection member 42. The weight detection member 41 is connected to the bracket 12 and is used to detect the weight of the liquid storage device 21. The distance detection member 42 is connected to the support rod 11 and detects the displacement of the support rod 11. One or both of the weight detection member 41 and the distance detection member 42 are installed in the support mechanism 1, wherein the weight detection member 41 can detect the change in the weight of the liquid storage device 21 per unit time. According to the relationship between the mass, density and volume of the flushing liquid, the change in the volume of the liquid storage device 21 per unit time, that is, the volume flow rate Q, can be obtained after conversion. Combined with the diameter D of the liquid pipe 22 and the flow formula Q=v*π*(D / 2)2, the value of the flow rate parameter v per unit time can be obtained, so that it can be judged whether the flow rate per unit time reaches the set value. The distance detection member 42 can detect the distance that the support rod 11 rises and falls. According to the formula for converting potential energy into kinetic energy, the flow rate of the flushing liquid is related to the height of the liquid storage device 21. Therefore, after the flow rate is set, the height of the liquid storage device 21 will be calculated by the flow rate, and the lifting drive member 31 will be used to automatically drive the support rod 11 to move to a suitable height. The distance detection member 42 detects the displacement of the support rod 11 to determine whether the liquid storage device 21 has moved into place in combination with the initial height of the liquid storage device 21. At the same time, the weight detection member 41 monitors the changes in the weight and volume of the liquid storage device 21 to ensure that the flow rate reaches the set flow rate.

The liquid tube 22 is relatively long, and when the liquid storage device 21 shakes, the shaking amplitude of the lower part of the liquid tube 22 will increase with the increase of the length. At the same time, the weight of the liquid tube 22 will also be detected by the weight detection member 41. In order to avoid the shaking of the liquid tube 22 from affecting the detection, and to make the main body of the weight detected by the weight detection member 41 as much as possible concentrated in the liquid storage device 21, the liquid tube 22 is fixed on the tube winding bracket 14, so that when the support rod 11 drives the liquid storage device 21 to rise and fall, the liquid tube 22 will not shake, and at the same time, the tube winding bracket 14 supports most of the weight of the liquid tube 22.

[0030] See also Figure 1 and Figure 3In order to straighten out the liquid pipe 22 and effectively fix the liquid pipe 22 and facilitate disassembly, a support plate 15 is provided on the pipe winding bracket 14.

When in use, the liquid tube 22 can first pass through the first tube clamping space 143 or the second tube clamping space 144 and be wound in the tube winding groove 151, and then pass through the second tube clamping space 144 or the first tube clamping space 143 to be led out. The first tube clamping space 143 and the second tube clamping space 144 can limit the two ends of the liquid tube 22, and further prevent the liquid tube 22 from loosening while straightening the liquid tube 22.
