[0002] In the modern medical field, the aspirator is an important surgical instrument and is widely used in various surgeries. The aspirator mainly uses negative pressure to suck away blood, body fluids, tissue fragments, etc. in the surgical area, thereby maintaining a clear surgical field of view and facilitating surgical operations. In ENT surgery, the aspirator can enter the nasal cavity or ear canal to remove secretions and foreign matter, keeping the surgical area clean and dry.

[0003] In order to increase the practical performance of the suction device, the flushing function is added to the original one. The double-lumen tube has two independent cavities, which are flushed with physiological saline, one for suction and the other for flushing. In this way, suction and flushing operations can be performed at the same time, improving the efficiency of the operation; but due to the small diameter of the double-lumen tube and the viscosity of blood, the double-lumen tube is easily blocked. During the operation, a rod can be used to clear it, or a wet gauze or vascular clamp can be used to remove foreign objects or residual blood clots, or a syringe can be used to draw an appropriate amount of saline to flush the blood clots clean, but this work process is relatively cumbersome and affects the efficiency of the operation.

[0023] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0024] Example

[0025] A flushing suction device described in this embodiment, such as Figure 1 and Figure 2 As shown, it includes a double-lumen pipeline 1, the double-lumen channels in the double-lumen pipeline 1 are independent of each other and are distributed up and down, the inlet end of the double-lumen pipeline 1 is connected to a switch body 2, and two channels are opened inside the switch body 2, which are respectively connected to the double-lumen channels of the double-lumen pipeline 1, and the two channels are distributed up and down, the channel located at the bottom is a flushing channel, and the channel located at the top is a suction channel;

[0026] like Figure 2 As shown, a connecting groove for connecting two channels is provided inside the switch body 2, and a connecting pipe 4 that can move up and down is arranged in the connecting groove, and the upper and lower ends of the connecting pipe 4 are in a closed state; the lower half of the connecting pipe 4 is provided with a first guide hole that is the same inside and outside, and the first guide hole is communicated with the inlet end of the channel located below, and the upper half of the connecting pipe 4 is provided with a second guide hole that is the same inside and outside, and the second guide hole is communicated with the outlet end of the channel located above; corresponding to the channel located below, a first through hole that is communicated left and right is provided on the connecting pipe 4; the right side of the switch body 2 is the inlet end of the channel, and the side close to the double-cavity pipe 1 is the outlet end of the channel; as shown Figure 2As shown, the upper and lower ends of the connecting groove pass through the flushing channel and the suction channel respectively. Under normal circumstances, the first through hole is connected to the flushing channel, and the inorganic saline enters from the flushing channel entrance and passes through the first through hole into the cavity below the double-lumen pipe 1 for flushing during the operation. Since the upper and lower ends of the connecting tube 4 are in a closed state, the inorganic saline in the flushing channel cannot enter the suction channel through the connecting tube 4; the connecting tube 4 has a high requirement for the matching accuracy with the connecting groove during the production process to avoid mutual leakage between the flushing channel and the suction channel; the first guide hole is located below the first through hole, and the second guide hole is located above the first through hole; the spacing between the first guide hole and the second guide hole is equal to the spacing between the two channels; the inner diameter of the channel is smaller than the outer diameter of the connecting tube 4, as shown in FIG. Figure 3 As shown, when the connecting tube 4 slides upward, the first guide hole communicates with the flushing channel, and the second guide hole communicates with the outlet end of the suction channel. The inorganic saline originally entering the double-lumen pipe 1 is intercepted and enters the connecting tube 4, and then enters the suction channel through the second guide hole, thereby introducing the inorganic saline in the flushing channel into the suction channel, flushing the upper cavity of the double-lumen pipe 1, completing the dredging of the upper cavity, and also facilitating flushing; the upper cavity of the double-lumen pipe 1 corresponds to the suction channel, and its lower cavity corresponds to the flushing channel;

[0027] In addition, during production, a limiting hook groove may be provided in the connecting groove, and a limiting protrusion may be fixed on the outer wall of the connecting pipe 4, and the limiting protrusion and the limiting hook groove may be slidably matched up and down, mainly to avoid the situation where the first guide hole and the flushing channel are misaligned due to the rotation of the connecting pipe 4;

[0028] like Figure 2 As shown, a first valve column 3 is arranged between the upper end of the connecting tube 4 and the lower end of the first spring 9, and a second through hole communicating left and right is opened on the first valve column 3 corresponding to the suction channel; when the first spring 9 is in a natural state, the second through hole on the first valve column 3 is communicated with the flushing channel; if the first valve column 3 is not arranged here, the lower end of the first spring 9 will directly pass through the suction channel and lean against the upper end of the connecting tube 4. During the suction process of the suction channel, although the first spring 9 will not block the passage of airflow, secretions and foreign matter are easily accumulated here to cause blockage, and the first valve column 3 can better avoid this situation;

[0029] A first spring 9 is provided between the upper end of the connecting tube 4 and the top of the connecting groove to push the connecting tube 4 downward. When the first spring 9 is in a natural state, the first through hole is connected to the flushing channel, that is, when no one is operating, the first through hole is connected to the flushing channel; a first button 5 is provided at the lower end of the connecting tube 4 to push the connecting tube 4 upward; Figure 2As shown, the first button 5 includes a pressing block, which is located below the switch body 2, and a limiting block independent of the connecting tube 4 is provided at the lower end thereof, and a mounting hole communicating with the inside and outside is provided between the connecting groove and the bottom of the switch body 2, and a connecting rod is independently installed in the mounting hole; one end of the connecting rod is inserted into the connecting groove and fixed on the limiting block, and the other end thereof is inserted through the mounting hole and fixed on the pressing block; the limiting block prevents the connecting rod from being separated from the mounting hole, and the first spring 9 is in a natural state, and the limiting block abuts against the lower end of the connecting groove, and the elastic force of the first spring 9 is broken by pressing the pressing block, so that the connecting tube 4 moves upward, and the first button 5 needs to be continuously pressed in the process of flushing or unblocking the upper cavity of the double-cavity pipeline 1;

[0030] like Figure 2 As shown, the switch body 2 has a valve slot arranged in a cross pattern with the channel, and a second valve column 7 movable up and down is arranged in the valve slot, and the side wall of the second valve column 7 fits with the slot wall of the valve slot, and a second spring 6 is installed between the upper end of the second valve column 7 and the top of the valve slot, and a third through hole communicating left and right is arranged on the second valve column 7 corresponding to the channel; a second button 8 for pressing the second valve column 7 is arranged on the switch body 2. This section as a whole constitutes a switch assembly for controlling the opening or closing of the channel, and the internal diameter of the channel is smaller than the diameter of the second valve column 7. When the second spring 6 is in a natural state, the third through hole is arranged in communication with the channel; when the second spring 6 is in a natural state, the channel is in an open state, and pressing the second button 8 compresses the second spring 6, and the third through hole is offset from the channel to close the channel; the structure of the second button 8 is the same as that of the first button 5, as shown in the following figure Figure 2 As shown; when in use, the two channels are controlled to work respectively by the two second buttons 8, switching back and forth between cleaning or suction, or both at the same time; in addition, the second spring 6 can be omitted, and the pressing activity of the second valve column 7 is changed to a rotating activity, and the third through hole and the channel are misaligned by rotating the second valve column 7 to control the switch, so that the second button 8 needs to be replaced by a knob;

[0031] like Figure 4 As shown, the switch body 2 is composed of two clamping plates symmetrically distributed front and back. During the production process, the switch body 2 is divided into two clamping plates equally divided front and back, which is conducive to installing the connecting pipe 4, the second valve column 7 and the second spring 6 and other components between the two clamping plates;

[0032] During actual use, the inlet end of the flushing channel in the switch body 2 is connected to the flushing device through a catheter, and the inlet end of the suction channel is connected to the negative pressure device through a catheter. Both the negative pressure device and the flushing device are prior art and belong to a type of medical device. During the operation, if the cavity on the double-cavity pipeline 1 is blocked due to tissue, at this moment, by pressing the first button 5, the connecting tube 4 moves upward, the first guide hole is the same as the inlet end of the flushing channel, and the second guide hole is connected to the outlet end of the suction channel. The inorganic saline in the flushing channel enters the suction channel through the connecting tube 4 to clear the blocked cavity of the double-cavity pipeline 1, and at the same time, the cleaning work can be completed. The operation method is simple and convenient, and can be completed with one hand.
