Detailed Implementation

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1 to 2 This utility model provides a handheld electric suction device for aspirating exudate, bleeding, pus, etc. during surgery. It mainly includes a suction device body 1, which comprises a housing 11 and a negative pressure generating component 12 disposed inside the housing 11. A suction connector 2 is installed at one end of the housing 11, detachably connected to the housing 11 and sealed to the internal negative pressure generating component 12. A storage tube 3 is detachably connected to the end of the housing 11 away from the suction connector 2 for storing the aspirated exudate. The storage tube 3 is sealed to the internal negative pressure generating component 12. During operation, pressing the suction control handle 13 on the housing 11 generates negative pressure. The generating component 12 generates negative pressure. Then, the tip of the suction connector 2 is aligned with the exudate to be absorbed. Under the pressure of the negative pressure, the exudate enters through the vacuum section in the middle of the suction connector 2, passes through the internal channel of the negative pressure generating component 12, and finally reaches the storage tube 3, where it is collected, thus completing the aspiration operation of the exudate during surgery. It should be noted that in this embodiment, the suction device body 1 is designed in the shape of a pistol, which is small in size, easy to hold and operate, and suitable for use in the surgical environment. In addition, the negative pressure generating component 12 can also generate positive pressure to clean the internal suction channel, prevent blockage of the internal channel, and perform deep cleaning of the internal channel to prevent bacterial growth.

[0020] Since this new device is primarily used for the absorption of exudate, it is understandable that the negative pressure function of the negative pressure generating component 12 is its main function. Furthermore, because the negative pressure and positive pressure functions are mutually exclusive, to avoid errors in the use of the suction device during surgery, please refer to [reference needed]. Figure 1 The suction control handle 13, which controls negative pressure, is designed to be larger than the cleaning button 14, which controls positive pressure. Furthermore, the suction control handle 13 is located at the four-finger bend grip area for easy operation. Specifically, the suction control handle 13 is hook-shaped, with the protruding end of the hook facing the cleaning button 14, thus separating the suction control handle 13 and the cleaning button 14. By setting the outer periphery of the suction control handle 13 to a hook shape, the operating space of the suction control handle 13 and the cleaning button 14 is separated, avoiding accidental activation.

[0021] Furthermore, the suction connector 2 includes a snap-fit ​​part 21 connected to the outer shell 11, and a suction head 22 connected to the snap-fit ​​part 21 at the end away from the outer shell 11. In order to facilitate the quick disassembly of the snap-fit ​​part 21 from the outer shell 11, the outer shell 11 is provided with a snap-fit ​​15 for quick disassembly of the suction connector 2 at the end near the second needle tube. By pressing the snap-fit ​​15 on the outer shell 11, the snap-fit ​​part 21 can be quickly disconnected from the outer shell 11, which facilitates the replacement, cleaning and sterilization of the suction connector 2.

[0022] See Figure 2 The snap-fit ​​portion 21 of the suction connector 2 is frustum-shaped. Further, the snap-fit ​​portion 21 includes a first end connected to the suction head 22 and a second end connected to the outer shell 11. In this embodiment, the first needle tube 221 is an integrally formed tube. The diameter of the inlet end 224 of the first needle tube 221 is set between 1.5mm and 5mm, which is used for the suction of exudate in small spaces during surgery. The outer diameter of the first needle tube 221 is smaller than the diameter of the first end of the snap-fit ​​portion 21. It should be noted that the first needle tube 221 and the snap-fit ​​portion 21 are connected to form an integral structure. The internal cavity is provided with a hollow aperture for the guidance of exudate. The aperture gradually increases from the inlet end 224 to the negative pressure generating component 12. This design can reduce clogging.

[0023] See Figure 3 and Figure 4In some embodiments, the suction head 22 connected to the latching part 21 includes a knob 222 and a second needle tube 223 passing through the knob. The knob 222 is provided with a spiral slide rail 2221, and the second needle tube 223 includes a second needle tube body 2231 and a sliding post 2232 provided on the second needle tube body 2231 and adapted to the slide rail 2221. When the knob 222 is rotated, the sliding post 2232 moves along the slide rail 2221 with the cooperation of the slide rail 2221 and the sliding post 2232. The movement of 2221 drives the movement of the second needle tube body 2231, realizing the extension and retraction function of the second needle tube 223. However, in order to prevent the second needle tube body 2231 from rotating when the knob 222 is rotated, a slider part 2233 is provided at the end of the second needle tube body 2231. The slider part 2233 can only slide linearly along the inner wall of the buckle part 21. It can be understood that the second needle tube body 2231 and the buckle part 21 are slidably connected by the slider part 2233.

[0024] Furthermore, the suction head 22 is made of stainless steel. Stainless steel is rust-resistant and has high structural strength, so the suction head 22 is not prone to bending or deformation, thus extending the service life of the suction connector 2.

[0025] In this embodiment, the storage tube 3 is equipped with an indicator light 31 to indicate its storage status. The storage tube 3 is a replaceable disposable consumable. Under normal use, the indicator light 31 of the storage tube 3 is green. When the storage tube 3 is full of exudate, the indicator light 31 turns red. At this time, the suction device body 1 automatically cuts off the power to indicate that the storage tube 3 needs to be replaced. To replace it, the storage tube 3 can be ejected by pressing the pop-out button on the outer shell 11, and then a new storage tube 3 can be installed. Additionally, a cleaning device identical to the connector of the storage tube 3 can be installed at the end where the storage tube 3 is installed. Then, by pressing the cleaning button 14, the negative pressure generating component 12 generates positive pressure, drawing the cleaning fluid from the cleaning device into the pipeline for cleaning.

[0026] In summary, the handheld electric suction device in the above embodiments of this utility model is designed with a small pistol-shaped structure, which is convenient to hold during surgery and reduces the burden on doctors during surgery; the handheld electric suction device is designed as an assembly type, which facilitates the replacement, cleaning and disinfection of the suction connector; the suction device collection device is designed as a replaceable disposable storage tube, avoiding the wiring burden caused by the collection device connected to the pipeline, and the disposable storage tube reduces bacterial growth and eliminates the cleaning and disinfection procedure.
