For another example, when a surgical operation is performed on fibroids, the liquid may be added with a physiological saline solution of a drug for stopping bleeding and promoting wound healing.
In an embodiment of the present invention, the pressure detection device 2 may be located at any position inside the water storage container 1, and the pressure detection device 2 does not shield the water inlet and the water outlet in the water storage container 1.
In an embodiment of the present invention, the implementation manner of triggering the water inlet valve 11 to close when the pressure detection device 2 detects that the pressure inside the water storage container 1 reaches the set pressure may include at least the following two manners:
mode 1: the closing of the water inlet valve 11 is controlled by the pressure intensity detection device 2.
In this mode 1, the pressure detection device 2 may include: the pressure detection sensor, the first controller and the first communication module. And the water inlet valve 11 is provided with a second controller and a second communication module.
In the mode 1, the pressure detection sensor is configured to detect a pressure in the water storage container 1 and send the detected pressure to the first controller, a set pressure is set in the first controller, and when the first controller determines that the pressure sent by the pressure detection sensor is equal to the set pressure, the first controller sends a control instruction to the first communication module, and the first communication module sends the control instruction to the second communication module. The second communication module sends the control instruction to a second controller, and the second controller controls the water inlet valve 11 to be closed.
Mode 2: the closing of the water inlet valve 11 is controlled by the operation operator.
In this mode 2, the pressure detection device 2 may include: a pressure detection sensor and a communication module.
In the mode 2, the pressure detection sensor is configured to detect the pressure inside the water storage container 1, send the detected pressure to the communication module, send the pressure inside the water storage container to the external terminal device through the communication module, and display the pressure inside the water storage container by the external terminal device. The operation operator manually controls the closing of the water inlet valve when the pressure in the water storage container is determined to reach the set pressure according to the pressure displayed on the external terminal equipment.
Regardless of the above mode 1 or the above mode 2, the set pressure may be determined according to a specific surgical operation, for example, the set pressure is 3 MPa.
In one embodiment of the present invention, in order to ensure that the liquid sprayed from the pen-knife can form a water knife, the pressure in the water storage container needs to be in a set range during the operation. Therefore, the liquid sprayed out of the knife pen can form a water knife under the action of the pressure in the water storage container.
For example, if the set pressure is 3MPa, the set range may be 2.5MPa to 3.5 MPa.
In an embodiment of the present invention, the implementation manner that the pressure in the water storage container is in the set range may include: when the outlet valve 13 is in an open state and the liquid in the water storage container 1 is output from the water outlet hole 12, the inlet valve 11 is opened to inject the liquid into the water storage container from the water inlet hole 10 by using the water inlet pipeline, and if the pressure in the water storage container is required to be always at the set pressure, the speed of outputting the liquid from the water outlet hole 12 needs to be ensured to be equal to the speed of injecting the liquid from the water inlet hole.
In one embodiment of the invention, since the pressure in the water storage container may vary within a set range, in order to ensure that the liquid can be sprayed from the knife pen during the operation, when the pressure in the water storage container is within the set range, the position of the water outlet hole is lower than the lowest liquid level position of the liquid in the water storage container. Wherein, the position of apopore can set up on water storage container's lateral wall or bottom.
In an embodiment of the present invention, before injecting liquid into the water storage container, gas is stored in the water storage container, if it is required that the pressure in the water storage container reaches a set pressure, the volume of the gas in the water storage container may need to be compressed, and before injecting liquid into the water storage container, the volume of the gas in the water storage container is equal to the volume of the water storage container, and if the pressure in the water storage container reaches the set pressure, the volume of the liquid stored in the water storage container is less, so as to increase the volume of the liquid stored in the water storage container, please refer to fig. 2, a gas outlet 14 and a gas outlet valve 15 may be disposed on the water storage container 1;
the water storage container 1 is further configured to discharge gas stored in the water storage container through the gas outlet 14 when the gas outlet valve 15 is in an open state and the water inlet valve 11 is in an open state;
wherein, the density of the gas stored in the water storage container 1 is less than that of the liquid injected from the water inlet 10. For example, the gas is air.
Wherein, whether to discharge a part of the gas in the water storage container 1 or discharge all the gas in the water storage container 1 can be determined according to the requirement.
Since the density of the gas stored in the water storage container 1 is lower than that of the liquid injected from the water inlet 10, the liquid is located under the gas when the liquid is injected from the water inlet 10 into the water storage container 1. Therefore, in one embodiment of the present invention, the air outlet 14 may be located at the top of the water storage container 1. When the air outlet 14 is located at the top of the water storage container 1, the air in the water storage container 1 can be completely or partially discharged.
In an embodiment of the invention, the air outlet hole may be located on a side wall of the water storage container 1, and a vertical distance from the air outlet hole 14 to the top of the water storage container 1 is not greater than a first set distance. Wherein the first set distance may be determined according to a desired volume of gas to be discharged. In this manner, the gas in the water storage tank 1 can be partially discharged.
In some cases, there may be a difference in the rate of fluid output from the outlet opening compared to the rate of fluid input from the inlet opening, which may result in a sudden change in pressure within the reservoir. For example, when the speed of outputting the liquid from the water outlet hole is higher than the speed of injecting the liquid from the water inlet hole, the pressure in the water storage container may be sharply reduced from 3MPa to 2.5MPa, and in this case, the strength of the water jet during the surgical operation may be sharply weakened, and even the surgical operation may fail.
In view of the above problem, in an embodiment of the present invention, referring to fig. 3, the water storage device may further include: an accumulator 3;
the energy accumulator 3 is provided with a water through hole 30 and a water through valve 31;

According to the energy accumulator, when the pressure in the water storage container is sharply reduced from 3MPa to 2.5MPa, in the process of reducing the pressure in the water storage container, the pressure in the water storage container is lower than the pressure in the energy accumulator, so that the opening of the water through valve is triggered, the energy accumulator presses liquid into the water storage container under the action of the pressure to increase the volume of the liquid in the water storage container, further, part of the reduced pressure in the water storage container is offset, the pressure in the water storage container is probably ensured to be reduced from 3MPa to 2.8MPa, and the effect of balancing pulsation is realized.
In an embodiment of the present invention, the shape of the energy accumulator may be at least any one of a cube, a cuboid, and a circle, and the embodiment is described by taking a cuboid as an example.
In order to ensure that the accumulator can achieve the effect of balancing the pulsation, the water passage hole 30 may be located at the bottom of the accumulator 3, and the density of the gas stored in the accumulator 3 is less than the density of the liquid injected from the water inlet hole 10. In this case, when the gas outlet valve 15 is in the open state, the gas stored in the accumulator 3 is not discharged from the gas outlet hole 14 as the liquid level of the liquid in the water storage tank 1 rises.
In one embodiment of the invention, the location of the accumulator within the water storage container may comprise: is positioned at the top of the water storage container, at the bottom of the water storage container or on the side wall of the water storage container.

the water outlet pipeline 51 is connected with the knife pen 50;
