[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] Reference Figs. 1 to 4 The present invention provides an embodiment of a rotatable, multi-angle spraying cryogenic therapy nozzle, including a handle 1. Its structural design facilitates hand-held operation by the operator, laying the foundation for stable control of the entire device. This allows the operator to stably control the device during cryogenic therapy. A connector 2 is provided at the top of the handle 1, which connects the handle 1 to components such as the square sleeve 16. It serves as the connection hub between the core components, ensuring that the various parts of the device can work together. Two connecting blocks 8 are fixedly connected to the left end of the connector 2, and a limiting ring 9 is fixedly connected to the left end of the connector 2. The limiting ring 9 cooperates with the connector 2 to ensure the stability of the connection between the limiting sleeve 11 and the connector 2, thereby improving the stability of the entire device's connection structure.

[0012] The left ends of the two connecting blocks 8 are fixedly connected to limiting rings 9, and the limiting sleeves 11 are slidably connected inside the rings 9 and cooperate with the connecting blocks 8 to ensure the stability of the connection between the square sleeve 16 and the connector 2, providing structural support for subsequent angle adjustment and material conveying. The left end of the connector 2 is provided with a connecting assembly, which includes an output tube 10, which has a limiting groove 15 inside for the limiting block 13 to be inserted. This is one of the key structures in the connecting assembly to achieve a stable connection, ensuring that the cryogenic material can be smoothly transferred from the connector 2 to the subsequent structure. The output tube 10 has a limiting groove 15 inside. There are two limiting grooves 15, which are opened inside the output tube 10, for the limiting block 13 to slide into, providing a locking position for the limiting block 13, and realizing a stable connection between the output tube 10 and the limiting sleeve 11. The limiting sleeve 11 is slidably connected to the outside of the output tube 10. The sliding rod 12 and the limiting block 13 slide inside the sleeve, and are slidably connected to the inside of the limiting ring 9. Through cooperation with the output tube 10, the limiting block 13, etc., a stable connection between the square sleeve 16 and the connector 2 is realized, providing reliable structural support for subsequent angle adjustment and material conveying.

[0013] The outer side of the limiting sleeve 11 is slidably connected to the inside of the limiting ring 9. The right end of the delivery hose 20 is fixedly connected to the left end of the limiting sleeve 11. The inside of the hose is used to deliver low-temperature treatment materials and is slidably connected to the inside of the first semicircular plate 19 and the second semicircular plate 23. The angle is adjusted by the rotation of the two semicircular plates, thereby driving the spray head 21 to rotate at multiple angles. The outer side of the limiting block 13 is slidably connected to the inside of the limiting groove 15. Under the action of the spring 14, it is accurately inserted into the limiting groove 15 of the output tube 10, realizing a stable connection between the limiting sleeve 11 and the output tube 10, thereby ensuring the stability of the connection between the square sleeve 16 and the connector 2. The outer side of the limiting block 13 is slidably connected to the inside of the limiting sleeve 11. The inside of the limiting sleeve 11 is slidably connected to two sliding rods 12, which drive the limiting block 13 to slide inside the limiting sleeve 11 in the connecting assembly, providing power and path for the movement of the limiting block 13, and helping the limiting block 13 to accurately insert into the limiting groove 15 of the output tube 10.

[0014] A spring 14 is sleeved on the outside of the sliding rod 12, which provides continuous elastic force to the limiting block 13, so that the limiting block 13 can be accurately and stably locked into the limiting groove 15 of the output tube 10, ensuring the connection stability of the connecting component. One end of the spring 14 is fixedly connected to the inside of the limiting sleeve 11, and the other ends of the two springs 14 are respectively fixedly connected to the far ends of the two limiting blocks 13. The near ends of the two sliding rods 12 are both fixedly connected to the limiting blocks 13. A square sleeve 16 is fixedly connected to the left end of the connecting component, which internally connects the rotating rod 17 and the rotating rod 22. It is the mounting carrier for the motor 18, motor 24 and other structures, providing installation and operating space for the angle adjustment structure.

[0015] The square sleeve 16 has two rotating rods 17 internally connected and fixed to a fixed block 25 externally. The rods rotate under the drive of a motor 18, which in turn drives the fixed block 25 and the semicircular plate 19 to rotate, thus realizing the transmission for angle adjustment. The external part of the delivery hose 20 is slidably connected to the inside of the semicircular plate 19. The bottom end of the motor 18 is fixedly connected to the top end of the square sleeve 16. After it is started, it drives the rotating rods 17 to rotate, providing power for the rotation of the semicircular plate 19. This is one of the power sources for realizing the spray angle adjustment.

[0016] The front end of motor 24 is fixedly connected to the rear end of square sleeve 16. After it is started, it drives rotating rod 22 to rotate, providing power for the rotation of semicircular plate 23. It is another power source for adjusting the spray angle. Motor 18 is set at the top of rotating rod 17. Fixed block 25 is fixedly connected to the outside of rotating rod 17. Semicircular plate 19 is fixedly connected to the outside of rotating rod 17. Rotating under the drive of rotating rod 17, it drives semicircular plate 19 to rotate, thereby adjusting the angle of delivery hose 20. Semicircular plate 19 is fixedly connected to the outside of two fixed blocks 25. Delivery hose 20 is slidably connected inside. Rotating under the drive of fixed blocks 25, it drives delivery hose 20 to adjust the angle, assisting the spray head 21 to rotate at multiple angles.

[0017] The square sleeve 16 has two rotating rods 22 internally connected to a fixed block 26 externally. Driven by a motor 24, these rods rotate, causing the fixed block 26 and the semicircular plate 23 to rotate, thus adjusting the angle. The rotating rods 22 are externally connected to the fixed block 26, which in turn connects to the semicircular plate 23. The rotating rods 22 rotate, causing the semicircular plate 23 to rotate, thus adjusting the angle of the conveying hose 20. The two fixed blocks 26 are externally fitted with semicircular plates 23, which are internally connected to the conveying hose 20. The hose 20 rotates under the action of the fixed block 26, thereby adjusting the angle of the delivery hose 20 and assisting the spray head 21 to rotate at multiple angles. The left end of one of the rotating rods 22 is fixedly connected to the motor 24. The delivery hose 20 is slidably connected inside the semi-circular plate 23. The left end of the delivery hose 20 is fixedly connected to the spray head 21, which receives the low-temperature material delivered by the delivery hose 20 and finally sprays out the low-temperature material to complete the low-temperature treatment operation. Moreover, it can achieve multi-angle spraying as the angle of the delivery hose 20 is adjusted to meet the needs of different treatment sites.

[0018] An observation screen 3 is installed on the bottom of the handle 1. During the equipment preparation and connection stages, the initial operating status of the equipment can be viewed. During the cryogenic material spraying process, the material delivery status and angle adjustment are continuously monitored in real time to ensure smooth material delivery and precise angle adjustment, thus ensuring the normal operation of cryogenic therapy. A connecting ring 4 is installed on the right end of the connector 2. A connecting tube 5 is installed inside the connecting ring 4. An arc-shaped piece 6 is fixedly connected to the outside of the connecting tube 5. The arc-shaped piece 6 is elastic and fits tightly against the outside of the left end of the material cavity 7 when the material cavity 7 is connected to the connecting tube 5, thus achieving initial fixation of the material cavity 7 and preventing the material cavity 7 from loosening or falling off during use. The two arc-shaped pieces 6 are elastic pieces. The right ends of the two arc-shaped pieces 6 fit against the outside of the left end of the material cavity 7. The material cavity 7 is slidably connected inside the connecting tube 5. It is used to fill the cryogenic therapy material and provide a material source for cryogenic therapy, ensuring that there is a sufficient amount of cryogenic material available for spraying during the treatment process.

[0019] Working Principle: First, the equipment is prepared and connected. The material cavity 7, filled with cryotherapy material, is connected to the connecting tube 5 at its left end. At this time, two elastic arc-shaped plates 6 will fit tightly against the outside of the left end of the material cavity 7, achieving initial fixation. Simultaneously, the observation screen 3 at the bottom of the handle 1 begins to function at this stage, used to check the initial operating status of the equipment, ensuring normal startup in subsequent processes. The handle 1's structural design facilitates handheld operation, laying the foundation for stable control of the entire device.

[0020] Next, the connecting assembly is operated to achieve a secure connection of the device. In the connecting assembly, the sliding rod 12 drives the limiting block 13 to slide inside the limiting sleeve 11, and the spring 14 provides continuous elastic force, causing the limiting block 13 to precisely engage in the limiting groove 15 of the output tube 10. Furthermore, the limiting sleeve 11 is slidably connected inside the limiting ring 9. Through this series of structural adjustments, the connection between the square sleeve 16 and the connector 2 becomes very stable, providing reliable structural support for subsequent angle adjustment and material conveying.

[0021] Next, motors 18 and 24 are activated for angle adjustment. When motor 18 starts, it drives the top rotating rod 17 to rotate, and the fixing block 25 outside the rotating rod 17 drives the semicircular plate 19 to rotate accordingly. Simultaneously, motor 24 starts, driving the left rotating rod 22 to rotate, and the fixing block 26 outside the rotating rod 22 further drives the semicircular plate 23 to rotate. Since the delivery hose 20 is slidably connected inside the semicircular plates 19 and 23, and its left end is fixedly connected to the spray head 21, the delivery hose 20 adjusts its angle with the rotation of the two semicircular plates, thereby driving the spray head 21 to rotate at multiple angles to adapt to the different spray angle requirements of different treatment sites.

[0022] Finally, the cryogenic material injection and real-time monitoring stage begins. The cryogenic material within the material chamber 7 travels sequentially through the connecting tube 5 into the connector 2, then through the output tube 10 and the limiting sleeve 11 into the delivery hose 20, and finally is ejected through the injection head 21, thus completing the cryogenic treatment operation. Throughout the process, the observation screen 3 continuously monitors the material delivery status and angle adjustment in real time, ensuring smooth material delivery and precise angle adjustment to guarantee the normal progress of the cryogenic treatment.

[0023] Through the above four-stage process, the handle 1 facilitates handheld operation, the connector 2 connects the core components, the connecting block 8 and the limiting ring 9 ensure connection stability, the motor 18 and the motor 24 achieve angle adjustment through the transmission structure, and the delivery hose 20 flexibly adjusts the angle in conjunction with the semi-circular plate. All components work together to ultimately realize the function of rotating and spraying at multiple angles, which can meet the diverse needs of spray angle and treatment range in different treatment scenarios.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
