DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figures 1 to 4 As shown, the utility model provides a visualized water therapy system, including a water jet assembly 1 and an endoscope 2. The water jet assembly 1 includes an outer sleeve 11, a pressure tube 12 and a negative pressure tube 13. The outer sleeve 11 is an outer protective structure, which is sleeved on the pressure tube 12, the negative pressure tube 13 and the periphery of the endoscope 2. The endoscope 2 is located between the pressure tube 12 and the negative pressure tube 13. The endoscope 2 is used to capture the image of the operating area in real time and transmit it to an external monitor, so that the surgeon can clearly observe the progress of the operation without direct visual observation and accurately locate the operation position, which significantly improves the accuracy and safety of the operation; the negative pressure tube 13 is used to extract liquid, blood and tissue fragments generated by cutting in the operating area to keep the surgical field clear. The pressure tube 12 is responsible for conveying high-pressure water flow, and one end of the pressure tube 12 has a nozzle 121, which can generate an extremely fine and high-speed water flow beam to achieve the purpose of cutting tissue; the outer sleeve 11 has a water retaining cap 111 arranged opposite to the nozzle 121 to limit the water flow from spraying in the direction of the target tissue, effectively avoiding the water flow from splashing outward and reducing accidental damage outside the operating area.

[0025] Based on the above structure, this embodiment introduces the endoscope 2, so that the water jet can observe the interaction between the water flow and the tissue in real time through the endoscope 2 located in the middle during operation, thereby visualizing the entire water jet treatment process, making the operation safer and more controllable, and avoiding the risks brought by "blind operation". At the same time, the structural design of the outer sleeve 11 and the water retaining cap 111, combined with the use of the negative pressure tube 13, effectively controls the direction and impact range of the water flow, further optimizes the surgical environment, reduces interference, and minimizes accidental damage to surrounding healthy tissues, thereby significantly improving the safety and success rate of the operation.

[0026] It can be understood that the water jet formed by the above structure is in a 90° direction with the outer sleeve 11, and the water jet is located at the front end of the visualized water treatment system, which is convenient for the doctor to separate the target tissue during operation and can remove the target tissue more thoroughly.

[0027] In some embodiments, the endoscope 2 is located at the axis of the outer sleeve 11, which can minimize the obstruction of the observation field by other components such as the tube wall of the outer sleeve 11, the pressure tube 12 or the negative pressure tube 13, ensuring that the lens of the endoscope 2 can obtain the best direct viewing angle, making the image obtained by the doctor through the endoscope 2 more intuitive and symmetrical, which helps to improve the accuracy of the surgical operation.

[0028] In some embodiments, the outer tube 11 also includes an outer tube body 112, and the outer tube body 112 has a tube cavity 1121 for accommodating the pressure tube 12, the negative pressure tube 13 and the endoscope 2, so that the pressure tube 12, the negative pressure tube 13 and the endoscope 2 work together in an integrated, protective outer shell, and the water retaining cap 111 is arranged at the end of the outer tube body 112, and is bent toward the nozzle 121 relative to the axial direction of the outer tube body 112. This structure can directly block and guide the high-speed water flow ejected from the nozzle 121, so that it can act more concentratedly on the target tissue and avoid unnecessary damage or interference caused by the dispersion of the water flow; in addition, the jet water flow can be better collected after the jet, and through the use of the negative pressure tube 13, the reabsorption of liquid and cutting products can be effectively promoted, the surgical field of view can be kept clear, and the visualization of the surgical process can be improved.

[0029] In some embodiments, the pressure tube 12 also includes a tube seal 122 and an inner nozzle 123 connected to the nozzle 121. The tube seal 122 is connected to one end of the inner nozzle 123 to form a closed end, sealing the terminal of the inner nozzle 123; the nozzle 121 is arranged on the side of the closed end so that a first angle is formed between the sprayed water jet and the inner nozzle 123, so that the water jet acts on the target tissue at a preset angle, thereby improving the operation flexibility and positioning accuracy during surgery. In addition, the lateral design of the nozzle 121 reduces the direct obstruction of the line of sight by the water flow. When used in combination with the endoscope 2, it can better maintain the clarity of the surgical field of view, reduce the direct impact of the water jet on the lens of the endoscope 2, and enable the doctor to continue to obtain a clear surgical field of view.

[0030] In some embodiments, the first angle is 75°-105°. If the angle is too small, the water flow may be too concentrated to effectively expand the cutting area, increasing the risk of local tissue damage; if the angle is too large, the water flow may be dispersed and the cutting efficiency may be reduced. The angle range of 75°-105° ensures that the water flow can effectively penetrate and separate tissues while maintaining sufficient control accuracy to reduce collateral damage to surrounding healthy tissues.

[0031] like Figure 5As shown, the negative pressure tube 13 includes a first tube body 131, and the first tube body 131 has a first pipe 1311 for liquid reflux, which is used to promote the reflux of liquid from the operating area to the negative pressure source, ensure a clear surgical field of view, and reduce liquid accumulation during the operation; a tube bevel 1312 is formed at one end of the first tube body 131 close to the nozzle 121. It can be understood that the tube bevel 1312 is inclined or conically contracted in shape, and faces the operating area or slightly biased toward the direction of the nozzle 121, which can more effectively guide and accelerate the liquid in the operating area to flow to the first pipe 1311, and use the dual effects of gravity and negative pressure to quickly clear liquid and debris in the surgical field of view, avoid crowding of the surgical space caused by liquid accumulation, reduce immersion of surrounding tissues, and keep the surgical field of view clear, which is crucial for the smooth progress of the operation.

[0032] In some embodiments, the negative pressure tube 13 has a water baffle 132 at one end close to the nozzle 121. The water baffle 132 is bent in a direction away from the nozzle 121 relative to the axial direction of the pressure tube 12 to form a second angle with the pressure tube 12. This prevents water from splashing downward through physical structural isolation, achieves effective water back-absorption, and more effectively controls the liquid flow path, guiding the liquid in the surgical area to flow toward the negative pressure tube 13. At the same time, it prevents high-pressure water from flowing back or splashing into the negative pressure system, thereby avoiding mutual interference between the high-pressure water flow and the negative pressure extraction process.

[0033] In some embodiments, the connection between the baffle 132 and the tube bevel 1312 is smoothly connected, making the transition between the two natural and smooth, so as to reduce the resistance and eddy current of water when passing through the two structures, ensure the smooth flow of liquid, and the two are connected to form a reflux guide portion, which can more efficiently guide the liquid, blood and tissue fragments in the surgical area to flow backward along the first pipe 1311 of the negative pressure tube 13, away from the surgical operation area.

[0034] In some embodiments, a negative pressure driving component 3 is also included, and the negative pressure driving component 3 is connected to the end of the negative pressure tube 13 away from the nozzle 121. That is, the negative pressure driving component 3 acts on the surgical area "remotely" through the negative pressure tube 13, and is responsible for extracting liquid and tissue fragments generated during the operation, reducing contamination of the surgical site, and speeding up the operation.

[0035] In some embodiments, the water jet assembly 1 further comprises a pressure driving member 4, which is connected to an end of the pressure tube 12 away from the nozzle 121, so as to pressurize the ordinary water flow and enable it to cut tissue with sufficient kinetic energy when passing through the nozzle 121.

[0036] In summary, the embodiment of the utility model provides a visualized water therapy system, which, through the introduction of the endoscope 2, can make the water jet observe the interaction between the water flow and the tissue in real time through the endoscope 2 located in the middle during operation, thereby visualizing the entire water jet treatment process, making the operation safer and more controllable, and avoiding the risks brought by "blind operation". At the same time, the structural design of the outer sleeve 11 and the water retaining cap 111, combined with the use of the negative pressure tube 13, effectively controls the direction and impact range of the water flow, further optimizes the surgical environment, reduces interference, and minimizes accidental damage to surrounding healthy tissues, thereby significantly improving the safety and success rate of the operation.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
