Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following is for reference. Figures 1-2 Description of a rinsing device 100 for an alpha masculinization handle according to an embodiment of the present invention.

[0027] like Figures 1-2 As shown, the rinsing device 100 for the phacoemulsification handle according to an embodiment of the present invention includes a rinsing box 10 and a rinsing assembly 20. The rinsing box 10 may define a water storage chamber 111, which may communicate with the channel inside the phacoemulsification handle. This allows for the storage of liquid (such as sterile water or purified water), increases the rinsing time of the channel (not shown in the figure) inside the phacoemulsification handle, increases the liquid pressure, and increases the flow rate of the liquid in the channel. This allows for the full discharge of the infusion fluid and crystals in the channel, improves the cleaning effect of the channel inside the phacoemulsification handle, and extends the service life of the phacoemulsification handle.

[0028] The rinsing assembly 20 can be installed on the rinsing box 10, and the rinsing assembly 20 can include a rinsing element (not shown in the figure). The rinsing element can communicate with the water storage chamber 111. The rinsing element can push liquid (such as sterile water or purified water) into the water storage chamber 111. The rinsing box 10 can have a vent 121 to balance the air pressure inside and outside the water storage chamber 111, which can ensure that the liquid enters the water storage chamber 111 smoothly and facilitates operation. Alternatively, the rinsing element can push air into the water storage chamber 111. On the one hand, it can pressurize the liquid and increase the flow rate of the liquid in the channel, which can fully discharge the irrigation fluid and crystals in the channel. On the other hand, it can dry the liquid in the channel after the liquid flows out of the channel, which can prevent the liquid or substances in the liquid (such as sterile substances) from remaining in the channel and reduce the safety risks of surgery.

[0029] According to the embodiment of the present invention, the flushing device 100 for the phacoemulsification handpiece is provided with a water storage chamber 111 communicating with the channel inside the phacoemulsification handpiece. By providing a flushing component to push liquid or air into the water storage chamber 111, liquid can be stored, the flushing time of the channel inside the phacoemulsification handpiece can be increased, the liquid pressure can be increased, the liquid flow rate in the channel can be increased, the irrigation fluid and crystals in the channel can be fully discharged, and liquid residue in the channel can be prevented. Therefore, the cleaning effect of the channel inside the phacoemulsification handpiece can be improved, the service life of the phacoemulsification handpiece can be increased, and the safety risks of surgery can be reduced.

[0030] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the flushing assembly 20 may further include a flushing pipe 21 and a one-way valve (not shown in the figure), one end of the flushing pipe 21 (e.g., Figure 2 The lower end shown can be connected to the flushing box 10, and one end of the flushing pipe 21 can be connected to the water storage chamber 111, while the other end of the flushing pipe 21 (as shown) can be connected to the water storage chamber 111. Figure 2 The upper end shown can be connected to the flushing component, and the other end of the flushing pipe 21 can be connected to the flushing component, so that the flushing component can push liquid or air into the water storage chamber 111 through the flushing pipe 21, thereby realizing the storage of liquid.

[0031] The flushing pipe 21 may have an opening 211 in its wall, through which the flushing component can draw in liquid or air. This allows the flushing component to draw in or push out liquid or air via a common path (such as the flushing pipe 21), which can save costs and facilitate operation. A one-way valve may be installed at the opening 211, allowing liquid or air to flow into the flushing component in one direction through the opening 211. This facilitates the flushing component drawing in liquid or air through the opening 211 and prevents liquid or air from flowing out of the opening 211 during the flushing component's process of pushing liquid or air into the water storage chamber 111. It also facilitates the flushing component pushing liquid or air into the water storage chamber 111 through the flushing pipe 21, which can improve the reliability and stability of the flushing device 100 in cleaning the channels inside the tumescent handle.

[0032] It is understandable that there can be one flushing pipe 21, and the flushing component can cooperate with the flushing pipe 21 to first draw in liquid and push the liquid into the water storage chamber 111, and then draw in air and push the air into the water storage chamber 111. Of course, there can be two flushing pipes 21. The flushing component can first cooperate with one flushing pipe 21 to draw in liquid and push the liquid into the water storage chamber 111, and then the flushing component can cooperate with another flushing pipe 21 to draw in air and push the air into the water storage chamber 111. There can be two flushing components, and the two flushing components can cooperate with two flushing pipes 21 respectively to draw in liquid or air and push the liquid or air into the water storage chamber 111.

[0033] It should be noted that a one-way valve (not shown in the figure) can be set at the connection between the flushing pipe 21 and the flushing box 10. This ensures that the flushing component pushes the liquid into the water storage chamber 111 through the flushing pipe 21 in one direction, and also ensures the flow rate of liquid or air drawn into the flushing component from the opening 211. Alternatively, each flushing pipe 21 can be equipped with two one-way valves. One one-way valve can be set at the opening 211, allowing liquid or air to flow into the flushing component in one direction through the opening 211. The other one-way valve can be set at the connection between the flushing pipe 21 and the flushing box 10. This prevents liquid or air from flowing out from the opening 211 during the flushing component's process of pushing liquid or air into the water storage chamber 111, and also prevents air from entering from the vent 121 when the flushing component draws in liquid or air through the opening 211. This ensures that the flushing component can smoothly draw in liquid or air and smoothly push the liquid or air into the water storage chamber 111, thereby improving the reliability and stability of the flushing device 100.

[0034] like Figure 1 and Figure 2As shown, in some embodiments, the flushing device 100 for the phacoemulsification handle may further include a first valve (not shown in the figure). The first valve may be located at the vent 121. The first valve may open or close the vent 121. The first valve may close the vent 121 so that the flushing component can draw in liquid through the opening 211. The first valve may also open the vent 121 to balance the air pressure inside and outside the water storage chamber 111 so that the flushing component can push the liquid into the water storage chamber 111, thereby achieving liquid storage.

[0035] Furthermore, the first valve can close the vent 121, allowing the flushing component to draw in air through the opening 211, and also allowing the flushing component to push the air into the water storage chamber 111. On the one hand, this can pressurize the liquid, increase the flow rate of the liquid in the channel, and fully discharge the irrigation fluid and crystals in the channel. On the other hand, it can dry the liquid in the channel after the liquid flows out of the channel, preventing the liquid or substances in the liquid (such as sterilizing substances) from remaining in the channel, and reducing the safety risks of the operation.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the flushing assembly 20 may further include a first drainage tube 22, one end of the first drainage tube 22 (e.g., Figure 2 The right end shown can be connected to the flushing tube 21 (e.g., a spiral connection), and the other end of the first drainage tube 22 (e.g., Figure 2 The left end shown can be connected to an infusion set (not shown in the figure) (such as a screw connection) for easy disassembly and assembly. One end of the first drainage tube 22 can be connected to the flushing tube 21 through the opening 211, which can increase the range of liquid and air extraction of the flushing device, ensure the cleaning effect of the channel in the phacoemulsification handle, and facilitate the arrangement of the flushing device 100 for easy operation. A one-way valve (not shown in the figure) can be set in the first drainage tube 22 so that liquid or air can flow into the flushing device in one direction through the first drainage tube 22 and the opening 211.

[0037] It is understood that the flushing device can draw liquid through the first drainage tube 22 and can directly draw air through the opening 211, which is convenient for operation. For example, there can be two flushing tubes 21. The first drainage tube 22 can be installed at the opening 211 of one flushing tube 21, so that the flushing device can draw liquid through the first drainage tube 22 on one flushing tube 21 and draw air through the opening 211 on the other flushing tube 21. Alternatively, there can be two first drainage tubes 22. The two first drainage tubes 22 can be installed at the openings 211 of the two flushing tubes 21 respectively, so that the flushing tube 21 can draw liquid or air through the first drainage tube 22 on the flushing tube 21.

[0038] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, in the vertical direction (e.g.) Figure 2 The rinsing element can be positioned on one side of the rinsing box 10 (as shown in the vertical direction). Figure 2 (as shown on the upper side), and in the direction close to the flushing element (e.g.) Figure 2 As shown in the top-to-bottom direction, the horizontal cross-section of the water storage chamber 111 gradually increases, which can improve the liquid storage effect. Based on ensuring the amount of liquid stored, it can increase the liquid level, increase the liquid pressure, increase the liquid flow rate in the channel, fully discharge the injection fluid and crystals in the channel, improve the cleaning effect of the channel in the phacoemulsification handle, and guide the liquid flow. It can ensure that the liquid in the water storage chamber 111 can be fully discharged through the channel, prevent the liquid from accumulating in the water storage chamber 111 for a long time, and facilitate cleaning.

[0039] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the rinsing box 10 may have an inlet 112, and the water storage chamber 111 may be connected to the channel inside the phacoemulsification handle through the inlet 112. Furthermore, the inlet 112 and the vent 121 may be located in the vertical direction of the rinsing box 10 (e.g., ...). Figure 2 The opposite sides (as shown in the up and down direction) on the following sides (e.g.) Figure 2 The upper and lower sides (as shown) can improve the liquid storage effect. Based on ensuring that the flushing device 100 can properly flush the channel inside the emulsification handle, it can prevent liquid leakage through the vent 121 and facilitate operation.

[0040] Understandably, the phacoemulsification handpiece typically has two channels: one channel for providing irrigation fluid into the eye to maintain intraocular pressure, and the other channel for aspirating tissue to ensure a clear field of vision during the procedure. The number of irrigation ports 112 can be one, which ensures effective cleaning of the channel and is easy to manufacture, thus reducing costs. Alternatively, the number of irrigation ports 112 can be two, which also ensures effective cleaning of the channel, reduces cleaning time, and is easier to operate.

[0041] like Figure 1 and Figure 2As shown, in some embodiments, the flushing device 100 for the phacoemulsification handle may further include a second valve (not shown in the figure). The second valve may be located at the inlet 112. The second valve may open or close the inlet 112. When the second valve closes the inlet 112, liquid or air may be drawn into the flushing element and pushed into the water storage chamber 111. This prevents liquid from leaking through the inlet 112 and the channel inside the phacoemulsification handle before storage is completed. When the second valve opens the inlet 112, the stored liquid may be concentrated and flushed through the inlet 112 to flush the channel inside the phacoemulsification handle. This increases the liquid pressure and the flow rate of the liquid in the channel, allowing the infused liquid and crystals in the channel to be fully discharged. This improves the cleaning effect on the channel inside the phacoemulsification handle and extends the service life of the phacoemulsification handle.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the flushing assembly 20 may further include a second drainage tube 23, one end of which (e.g., Figure 2 The upper end shown can be connected to the flushing box 10 (e.g., spiral connection) for easy assembly and disassembly. One end of the second drainage tube 23 can be connected to the water storage chamber 111 through the filling port 112, and the other end of the second drainage tube 23 (e.g., the upper end shown) can be connected to the flushing box 10 (e.g., spiral connection) for easy assembly and disassembly. Figure 2 The lower end shown is connected to the phacoemulsification handle, and the other end of the second drainage tube 23 can communicate with the channel inside the phacoemulsification handle, which can increase the working range of the flushing device 100, ensure the cleaning effect of the channel inside the phacoemulsification handle, facilitate the arrangement of the flushing device 100, and facilitate operation.

[0043] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the rinsing box 10 may include a box body 11 and a cover 12. The box body 11 may define a water storage chamber 111. The cover 12 and the box body 11 are detachably connected. The cover 12 may move relative to the box body 11 to open or close the water storage chamber 111, which is beneficial for cleaning the water storage chamber 111. The cover 12 may have a vent 121. The rinsing component 20 may be installed on the cover 12, and the rinsing component may communicate with the water storage chamber 111. Thus, by disassembling and assembling the cover 12 and the box body 11, the rinsing component 20 can be disassembled and assembled, which is convenient for operation and maintenance.

[0044] According to some embodiments of this utility model, the flushing component can be a syringe, which can reduce costs and facilitate operation.

[0045] According to some embodiments of this utility model, the channel inside the phacoemulsification handle is generally too narrow and too long, which increases the resistance to liquid flow and generates tension on the liquid to hinder its flow. Therefore, when the flushing component does not push air into the water storage chamber 111 to increase the liquid pressure, the liquid itself cannot automatically pass through the narrow channel inside the phacoemulsification handle to clean the channel by its own gravity and pressure, which is beneficial for the water storage chamber 111 to store liquid.

[0046] Other configurations and operations of the rinsing device 100 for an phacoemulsification handle according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here. In the description of the present invention, "first feature" and "second feature" may include one or more of the aforementioned features. The vertical, horizontal, and front-back directions are defined as shown in the figures.

[0047] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them. Moreover, "above," "over," and "on top" of the second feature include the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0048] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
