Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a water jet system. Background Art

[0002] Liquid jetting is a technology that uses high-pressure water to spray out from a nozzle hole with a tiny aperture at high speed, forming a high-energy-density jet to impact the material and break it up, and water jets use this technology. The existing liquid jet system power source uses a high-pressure pump to drive the system. The high-pressure pump uses the reciprocating motion of the internal cylindrical piston to allow the fluid to enter and leave the pump chamber. This mechanism causes the fluid delivered by the high-pressure pump to have unstable pressure. The reciprocating motion of the piston sucks in and pushes out the fluid. During low-frequency reciprocating motion, the pump body outputs the fluid intermittently; during high-frequency reciprocating motion, although the pump body does not output the fluid intermittently, the pressure of the output fluid is unstable. In addition, the high-pressure pump has very high requirements for the processing accuracy of the size, cylindricity and coaxiality of the piston and the pump body. In order to ensure good airtightness between the piston and the pump chamber wall, the processing of the high-pressure pump structural parts is difficult and the manufacturing cost is high.

[0047] Example 1

[0048] like Figure 1-Figure 2As shown, this embodiment provides a water jet system, including a high-pressure gas tank module 10, a liquid nozzle module 20, a cutter head module 30 and a valve module 40; wherein, the liquid nozzle module 20 stores liquid 80, the high-pressure gas tank module 10 is used to provide a high-pressure gas source for the liquid nozzle module 20, the cutter head module 30 is configured to spray a liquid jet when the high-pressure gas tank module 10 applies pressure to the liquid 80 in the liquid nozzle module 20, and the valve module 40 is arranged between the high-pressure gas tank module 10 and the liquid nozzle module 20, and the valve module 40 is configured to provide a stable pressure to the liquid 80 in the liquid nozzle module 20.

[0049] In the above embodiment, the water jet system adopts a modular design to facilitate subsequent design improvements and updates of the system, and also facilitate maintenance and repair of the equipment.

[0050] It should be noted that the liquid 80 is physiological saline or other physiologically compatible liquid.

[0051] In the specific implementation method, please combine Figure 1-Figure 6 To understand, the liquid nozzle module 20 includes a cylinder body 21, and a piston 24 is arranged inside the cylinder body 21. The piston 24 divides the interior of the cylinder body 21 into two chambers. The cylinder body 21 is provided with an air inlet 22 and a liquid outlet 23. One of the chambers is connected to the air inlet 22 to form a gas chamber, and the other chamber is connected to the liquid outlet 23. The chamber connected to the liquid outlet 23 is used to contain liquid 80 to form a liquid chamber; the high-pressure gas tank module 10 is connected to the air inlet 22 pipeline so as to provide a stable high-pressure gas source for the gas chamber through the high-pressure gas tank module 10, and the cutter head module 30 is connected to the liquid outlet 23 pipeline. When the high-pressure gas enters the gas chamber, it can push the piston 24 to compress the volume of the liquid chamber. Since the liquid is incompressible, the liquid 80 in the liquid chamber is ejected through the cutter head module 30 to form a high-energy density liquid jet, so as to impact and crush the target object.

[0052] In the above embodiment, a high-pressure gas tank module 10 is provided to provide a high-pressure gas source for the liquid nozzle module 20, thereby realizing energy transfer using the high-pressure gas source as a power source, and directly pushing the fluid in the liquid nozzle module 20 out of the cutter head module 30 to form a jet of sprayed liquid, which can replace the existing high-pressure pump, and then the valve module 40 controls the opening to provide a stable pressure to the liquid 80 in the liquid nozzle module 20, so that the output fluid pressure of the cutter head module 30 is stable; and the use of high-pressure pneumatics can effectively improve the dynamic performance and stiffness of the pneumatic system, and has the advantages of a small output force-to-system weight ratio, high speed and component miniaturization, thereby saving installation space, etc.; the utility model uses a high-pressure gas source as a power source to drive liquid injection, which can ensure the stability of the output fluid pressure; the water jet system eliminates the high-pressure pump, and has the advantages of simple structure, low cost, small space occupation, convenient maintenance, and easy processing and manufacturing of spare parts.

[0053] In this embodiment, since the high-pressure pump sucks in and pushes out the fluid through the reciprocating motion of the piston, the fluid pressure may fluctuate. Therefore, this embodiment uses a high-pressure gas source to overcome the problem of unstable output fluid pressure caused by the high-pressure pump sucking and pushing the fluid, and can continuously output fluid with stable pressure. The high-pressure gas drive principle is essentially the same as that of the high-pressure pump. The high-pressure gas drive drives the fluid in the liquid chamber by pushing the piston 24 with gas pressure, and the piston 24 maintains unidirectional motion.

[0054] Also, since the high-pressure pump outputs low-pressure water flow through the low-frequency reciprocating motion of the piston, there may be a phenomenon that the water flow pressure cannot keep up, resulting in the water flow being unable to form a jet of water. There is also a problem of poor pressure control accuracy under low pressure. For this reason, the present embodiment uses a high-pressure air source to effectively solve the problem of poor working effect of the high-pressure pump when the liquid injection is in a low-pressure state, and there is no phenomenon of pressure not keeping up.

[0055] In some embodiments, the high-pressure gas tank module 10 includes an air compressor 11, an air source processing unit 12, a pneumatic control unit 13 and a speed regulating valve 14 connected in sequence, and the speed regulating valve 14 is connected to the valve module 40 through a pipeline; specifically, the air source processing unit 12 includes a filter 121 and a dryer 122, the filter 121 and the dryer 122 are connected through a pipeline, the filter 121 is connected to the air compressor 11 through a pipeline, and the dryer 122 is connected to the pneumatic control unit 13 through a pipeline; in this way, the outside air is directly pressurized by the air compressor 11 to form a high-pressure gas source, and the outside air is filtered by the filter 121 and dried by the dryer 122 before being transported into the gas chamber, thereby ensuring the cleanliness of the gas chamber and avoiding gas leakage and contamination of the liquid; the expansion of high-pressure compressed air is used to do work, and the high-pressure compressed air is used to provide power for the piston 24; the high-pressure gas source is produced by the air compressor 11, and the energy transfer is fast and the storage is easy.

[0056] In some embodiments, the valve module 40 includes a switch valve 41, a pressure reducing valve 42 and a solenoid valve 43. The switch valve 41 is used to connect the speed control valve 14 and the pressure reducing valve 42, and the solenoid valve 43 is used to connect the pressure reducing valve 42 and the air inlet 22. In the process of providing power to the gas chamber of the cylinder body 21 by setting a high-pressure gas source, the pressure reducing valve 42 is required to perform preliminary pressure reduction, and then the solenoid valve 43 delivers a stable high-pressure airflow to the gas chamber of the cylinder body 21.

[0057] In some embodiments, a controller 70 and a plurality of pressure sensors 50 are further included. The plurality of pressure sensors 50 are respectively used to detect the pipeline air pressure between the switch valve 41 and the pressure reducing valve 42, the pipeline air pressure between the switch valve 41 and the pressure reducing valve 42, the pipeline air pressure between the pressure reducing valve 42 and the solenoid valve 43, and the air pressure in the liquid nozzle module 20; the plurality of pressure sensors 50 are electrically connected to the controller 70, and the controller 70 is configured to control the valve opening of the switch valve 41, the pressure reducing valve 42 or the solenoid valve 43 according to the air pressure value fed back by the pressure sensor 50; the solenoid valve 43 is controlled to deliver a stable high-pressure airflow to the liquid nozzle under the interaction between the pressure sensor 50 and the controller 70. The plurality of pressure sensors 50 can monitor the gas pressure in the pipeline in real time at multiple locations of the gas path.

[0058] In other embodiments, the high-pressure gas may not be supplied during the jet injection process. Therefore, a certain space (gas chamber) capacity needs to be reserved at one end of the cylinder 21 close to the air inlet 22 to act as a pressure-stabilizing space, which is equivalent to acting as a larger pressure-stabilizing gas source.

[0059] In some embodiments, a speed sensor 60 is provided in a chamber connected to the air inlet 22, and the speed sensor 60 is used to detect the moving speed of the piston 24. The speed sensor 60 can monitor the movement of the piston 24 in real time, so that the pressure in the cylinder 21 and the monitoring of the piston movement can achieve more accurate control of the movement of the liquid 80.

[0060] In this embodiment, the cylinder 21 and the piston 24 have both high-pressure air tightness and liquid tightness.

[0061] Example 2

[0062] Compared with Example 1, the difference of Example 2 is:

[0063] like Figure 7As shown, the cylinder body 21 includes a first cylinder body 21a and a second cylinder body 21b which are connected. The diameter of the first cylinder body 21a is larger than the diameter of the second cylinder body 21b. The piston 24 is an I-shaped structure. The two ends of the piston 24 are respectively placed in the first cylinder body 21a and the second cylinder body 21b. The air inlet 22 is connected to the first cylinder body 21a, and the liquid outlet 23 is connected to the second cylinder body 21b. The second cylinder body 21b is used to contain the liquid 80. Therefore, since the diameter of the first cylinder body 21a is larger than the diameter of the second cylinder body 21b, the diameter of the end of the piston 24 placed in the first cylinder body 21a is larger than the diameter of the end of the piston 24 placed in the second cylinder body 21b. The contact area between the piston 24 and the high-pressure gas source is larger than the contact area between the piston 24 and the liquid, so that the piston 24 forms a booster piston. The booster piston can increase the pressure of the high-pressure gas, and then transfer it to the liquid 80 in the second cylinder body 21b, thereby achieving a boosting effect.

[0064] In this embodiment, the first cylinder body 21 a , the second cylinder body 21 b and the piston 24 have both high-pressure air tightness and liquid tightness.

[0065] Example 3

[0066] Compared with Example 1, the difference of Example 3 is:

[0067] like Figure 8 As shown, the liquid nozzle module 20 includes a cylinder 21, a water bag 25 is arranged in the cylinder 21, an air inlet 22 is connected to the cylinder 21, and a liquid outlet 23 is connected to the water bag 25. In this embodiment, the water bag 25 is made of a flexible material and can be deformed under pressure. The water bag 25 contains liquid 80, and the gas and liquid are separated into two parts independently through the water bag 25, and a piston is no longer required.

[0068] In this embodiment, high-pressure gas enters the cylinder 21 through the air inlet 22, and the water bag 25 in the cylinder 21 can squeeze the liquid 80 out of the liquid outlet 23 under the action of the high-pressure gas, thereby forming a high-speed liquid jet.

[0069] In some embodiments, the water bag 25 can be designed to be detachable to facilitate the replacement of the water bag 25 as a whole and to meet the requirements of medical sterilization.

[0070] Example 4

The liquid 80 is stored in the retractable water bag 26, and the retractable water bag 26 can be retracted in the horizontal direction under the action of the high-pressure gas in the cylinder 21, so that the retractable water bag 26 can be driven to squeeze the liquid out of the liquid outlet 23 to form a high-speed liquid jet.

[0073] In some embodiments, the liquid 80 is stored in the telescopic water bag 26 and can be designed to be detachable, which is convenient for replacing the entire telescopic water bag 26 and can also meet the requirements of medical sterilization.

[0074] Example 5

[0075] Compared with Example 4, the difference of this Example 5 is:

[0076] like Fig.10 As shown, the liquid nozzle module 20 includes a cylinder 21, in which a retractable water bag 26 and a retractable air bag 27 are arranged, the air inlet 22 is connected to the retractable air bag 27, and the liquid outlet 23 is connected to the retractable water bag 26. The retractable water bag 26 and the retractable air bag 27 can be retracted in the horizontal direction. In this embodiment, the gas and the liquid are stored in the retractable air bag 27 and the retractable water bag 26 respectively. The retractable air bag 27 receives high-pressure gas through the air inlet 22, and the liquid 80 is stored in the retractable water bag 26. The retractable water bag 26 is placed in the cylinder 21, and the retractable water bag 26 is driven by the retractable air bag 27 to squeeze the liquid out of the liquid outlet 23 to form a high-speed liquid jet.

[0077] In some embodiments, the liquid is stored in the retractable water bag 26, and the retractable water bag 26 is detachably connected to the cylinder 21, which is convenient for replacing the retractable water bag 26 as a whole and for meeting the requirements of medical sterilization. The gas is stored in the retractable air bag 27, and the high-pressure air tightness and liquid tightness of the cylinder 21 can be ignored, thereby simplifying the structure and reducing the requirements for the structure.

[0078] In summary, the embodiment of the utility model provides a water knife system, which provides a high-pressure gas source for the liquid nozzle module 20 by setting a high-pressure gas tank module 10, thereby realizing energy transfer with the high-pressure gas source as the power source, and directly pushing the fluid in the liquid nozzle module 20 out of the cutter head module 30 to form a jet of sprayed liquid, which can replace the existing high-pressure pump, and then control the opening of the valve module 40 to provide a stable pressure to the liquid 80 in the liquid nozzle module 20, so that the output fluid pressure of the cutter head module 30 is stable; and the use of high-pressure pneumatics can effectively improve the dynamic performance and stiffness of the pneumatic system, and has the advantages of a small output force-to-system weight ratio, and can achieve high speed and miniaturization of components, thereby saving installation space and the like; the utility model uses a high-pressure gas source as a power source to drive liquid injection, which can ensure the stability of the output fluid pressure; the water knife system eliminates the high-pressure pump, and has the advantages of simple structure, low cost, small space occupation, convenient maintenance, and easy processing and manufacturing of spare parts.
