Example

[0018] As attached Figure 1 To be continued Figure 8 As shown: A flap separation rod for rinsing wounds includes a handle 1 and a separation rod 3. One end of the handle 1 is fixedly connected to one end of the separation rod 3, and the other end of the handle 1 is provided with a negative pressure suction port 2. The other end of the separation rod 3 has several drainage ports 301. An injection port 4 is provided on the side of the connection between the handle 1 and the separation rod 3. The handle 1, the separation rod 3, and the injection port 4 are connected by a selector valve 5. Hollow pipes are provided inside the handle 1, the negative pressure suction port 2, the separation rod 3, and the injection port 4, and are selectively connected through the selector valve 5. The selector valve 5 can be a three-way valve with a "T-shaped flow channel," such as a plug valve or a ball valve. Selector valve 5 has a first position and a second position. When selector valve 5 is rotated to the first position, only the pipes inside handle 1, negative pressure suction port 2, separation rod 3 and drainage port 301 are connected, while the pipe inside injection port 4 is blocked. When selector valve 5 is rotated to the second position, only the pipes inside drainage port 301, separation rod 3 and injection port 4 are connected, while the pipe inside handle 1 is blocked.

[0019] Furthermore, in this embodiment, valve 5 is selected as a plug valve, including a valve body 502 integrally formed with the handle 1 and a plug 501 rotating within the valve body 502. The inner wall of the valve body 502 and the outer wall of the plug 501 form a seal. The plug 501 includes a cylindrical plug core 5011, and a "T"-shaped fluid channel 5012 for controlling the fluid flow direction is opened in the middle of the plug core 5011. Compared with other valve bodies such as ball valves, the plug valve body of the preferred plug valve in this embodiment can be integrally formed with the handle 1, which simplifies the assembly process and reduces costs.

[0020] Furthermore, in this embodiment, the top of the plug core 5011 is provided with an on indicator 5013A and an off indicator 5013B, and the included angle between the on indicator 5013A and the off indicator 5013B is 90°. When the selector valve 5 is rotated to the first position, the conduction indicator 5013A points towards the separation rod 3, and the closing indicator 5013B points towards the injection port 4. When the selector valve 5 is rotated to the second position, the on indicator 5013A points towards the injection port 4, and the off indicator 5013B points towards the negative pressure suction port 2. This provides a clear indication and reduces the risk of misoperation.

[0021] Furthermore, in this embodiment, both the on indicator switch 5013A and the off indicator switch 5013B are provided with indicator markings on their tops. In this embodiment, the on indicator switch 5013A is provided with a "double-headed arrow" pattern, and the off indicator switch 5013B is provided with the word "OFF".

[0022] Furthermore, in this embodiment, the outer side of the top of the plug core 5011 is provided with a flange, and a limiting groove 5014 is formed on the flange. The top of the valve body 502 is provided with a corresponding protruding stop block 5021. The horizontal angle between the two side walls of the limiting groove 5014 and the axis of the plug core 5011 is 90°. When the selector valve 5 is rotated to the first position, the stop block 5021 abuts against one side of the limiting groove 5014. When the selector valve 5 is rotated to the second position, the stop block 5021 abuts against the other side of the limiting groove 5014. This forms the dead point positions of the two positions, which can accurately position and realize accurate control of the two positions. Furthermore, in this embodiment, the outer side wall of the bottom end of the plug core 5011 is provided with an annular groove 5015, and the inner side wall of the bottom end of the corresponding valve body 502 is provided with an annular boss 5022. When the plug core 5011 is inserted into the valve body 502, the annular groove 5015 and the annular boss 5022 engage. This achieves a stable connection between the plug body 501 and the valve body 502. The annular boss 5022 has a chamfer facing the direction of insertion of the plug body 501 to facilitate insertion.

[0023] Furthermore, in this embodiment, the end of the separation rod 3 is bullet-shaped with a smooth transition to avoid sharp parts injuring the patient.

[0024] Furthermore, in this embodiment, the drainage port 301 is opened on the side of the end of the separating rod 3. The drainage port 301 is teardrop-shaped, and there are 3 drainage ports 301 to increase the guiding and drainage effect.

[0025] Furthermore, in this embodiment, the surface of the handle 1 is provided with anti-slip texture, which makes it easy to grip, increases friction, and reduces the risk of slippage.

[0026] Furthermore, in this embodiment, both the injection port 4 and the negative pressure suction port 2 are Green tips, which facilitate connection with external catheters.

[0027] How to use: When flap separation surgery is required, connect the inlet 4 to the cleaning fluid (such as saline) tubing and the negative pressure suction port 2 to the negative pressure bottle tubing beforehand. Rotate the valve to the first position, and the doctor can directly operate the flap separation surgery by holding the handle 1. In this mode, the excised human skin tissue can be sucked into the external negative pressure bottle through the channel formed by the drainage port, separation rod, selection valve, handle, and negative pressure suction port. After the flap separation is completed, when it is necessary to rinse the surgical wound, simply rotate the selection valve 5 to the second position. The pre-filled cleaning fluid (such as saline) can be directly injected into the patient's wound through the channel formed by the inlet 4, selection valve, separation rod, and drainage port, quickly rinsing the wound. This simplifies the steps of flap separation surgery and wound rinsing for the doctor, making the operation more convenient, reducing the use of instruments, and improving efficiency.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the utility model without departing from the scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
