[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0021] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0022] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, an embodiment of the utility model is a suction tube, including a tube body, wherein the tube body is used to be connected to a suction device, wherein a channel 1 for the suctioned material to pass through is provided inside the tube body, wherein one end of the tube body is a connecting section 2 for being connected to the suction device, and the other end of the tube body is a suction section 3 for suction, wherein a corrugated expansion section 4 is provided between the connecting section 2 and the suction section 3, and the connecting section 2 is relatively expanded or bent with respect to the suction section 3 via the corrugated expansion section 4.

[0024] The beneficial effects of such a setting are as follows: the suction tube of the utility model adopts a bendable and retractable structure, the shape of the suction tube can be adjusted, occupying a smaller space, avoiding affecting other operations during surgery, providing a better field of view, and the structure of the corrugated telescopic tube is easy to use, achieving quick adjustment and improving efficiency.

[0025] It is further provided that a side hole 5 is opened on a side wall of one end of the attraction section 3 close to the connection section 2 , and the side hole 5 communicates the outside of the tube body with the inside of the channel 1 .

[0026] The beneficial effects of such a setting are as follows: the pressure in the channel inside the suction tube is controlled by opening or closing the side hole, so that the suction tube can be controlled to switch between the suction state and the stop suction state. When the side hole is closed, the pressure inside the channel is reduced to form a negative pressure state, and the suction tube performs suction. When the side hole is open, the pressure inside the channel is the same as the pressure outside, and the suction tube stops suction. In this embodiment, the size of the side hole is controlled to be smaller than the size of a finger, so that the side hole can be blocked with a finger, which further simplifies the operation and is more suitable for use during surgery.

[0027] It is further provided that a partition plate 6 is axially provided inside the suction section 3 , and the channel 1 is divided into a plurality of first suction flow channels 7 by the partition plate 6 .

[0028] The beneficial effect of such a configuration is as follows: the partition divides the channel into several first suction channels with smaller inner diameters, which can prevent the suction tube from sucking in materials such as broken bones that may block the channel, thereby acting as a sieve to ensure normal flow of the channel.

[0029] It is further configured that a plurality of auxiliary tubes 8 are evenly distributed inside the suction section 3 , each of the auxiliary tubes 8 has the same inner diameter, and each of the auxiliary tubes 8 has a circular cross-section, and each of the auxiliary tubes 8 is provided with a second suction channel 9 inside.

[0030] The beneficial effects of such a configuration are as follows. As another embodiment, the suction tube is separated by a plurality of circular sub-tubes, and a plurality of second suction flow channels are used for the suctioned material to flow, which can also act as a screen. Each sub-tube has an independent outer wall, and has a higher structural strength. The second suction flow channel is not easy to be blocked, thereby preventing the suction tube from being scratched.

[0031] It is further provided that one end of the suction section 3 away from the connecting section 2 is a suction port 10 , and an expansion port 11 is extended outward from the edge of the suction port 10 , and the inner diameter of the expansion port 11 is larger than the inner diameter of the suction port 10 .

[0032] The beneficial effects of such a configuration are as follows: the suction port has a larger suction area through the expansion with a larger inner diameter, thereby increasing the suction force and improving the efficiency of clearing the patient's respiratory secretions, blood or other body fluids.

[0033] It is further configured that the attraction section 3 is configured in a conical structure, an end of the attraction section 3 away from the connecting section 2 is a suction port 10 , and a radius of an end of the attraction section 3 close to the connecting section 2 is larger than a radius of the suction port 10 .

[0034] The beneficial effects of such a configuration are as follows: when broken bones or soft tissues are sucked into the suction tube, it is easy to cause blockage at one end of the suction section close to the connecting section, that is, the middle part of the suction tube. The suction section is configured in a conical structure to prevent blockage. If broken bones or soft tissues are sucked into the suction tube, they can also flow smoothly, greatly reducing the possibility of blockage.

[0035] It is further provided that the radius of the suction section 3 close to one end of the connecting section 2 is between 0.7 and 0.9 cm, and the radius of the suction port 10 is between 0.5 and 0.7 cm.

[0036] The beneficial effects of this arrangement are as follows: in this embodiment, the radius of the suction section close to one end of the connecting section is 0.8 cm, and the radius of the suction port is 0.6 cm. The suction section adopts this size to ensure normal suction without being too thick to affect the field of vision.

[0037] It is further configured that the material of the tube body is PVC.

[0038] The beneficial effects of this arrangement are as follows: PVC is a synthetic plastic formed by the polymerization of vinyl chloride monomer under the action of initiators such as peroxides and azo compounds, or according to the free radical polymerization mechanism under the action of light and heat. The transparent plastic facilitates real-time observation of the suction situation inside the suction tube, further reducing obstruction of the field of vision, and has lower cost and strong plasticity.

[0039] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
