Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] A surgical suction device includes: a base 1, a material holding mechanism 2, an air guiding mechanism 3, and a suction mechanism 4;

[0031] The air guiding mechanism 3 includes an air distribution component and an air exchange component; the air distribution component is fixedly connected to and communicates with the material holding mechanism 2; the air distribution component is fixedly connected to and communicates with the air exchange component; the suction mechanism 4 includes a suction component and a suction head 82; one end of the suction component passes through the material holding mechanism 2, and the other end is fixedly connected to and communicates with the suction head 82; the suction component is detachably connected to the chassis 1 through the suction head 82.

[0032] The bottom end of the suction head 82 is fixedly connected to the top surface of the chassis 1; the material receiving mechanism 2 is fixedly connected to the top surface of the chassis 1.

[0033] Further optimization of the scheme: the air distribution component includes an air outlet pipe 31; one end of the air outlet pipe 31 is fixedly connected to and communicates with the material holding mechanism 2, and the other end is fixedly connected to and communicates with an air collection box 32; three air distribution pipes 33 are fixedly connected to and communicates with the side of the air collection box 32, and the air distribution pipes 33 can divide the air drawn out from the material holding mechanism 2 into three equal parts, which facilitates the adjustment of the negative pressure in the cavity of the material holding mechanism 2; the three air distribution pipes 33 are fixedly connected to and communicate with the ventilation component; an air suction machine 34 is fixedly installed in the inner cavity of the air outlet pipe 31, and the air suction machine 34 suctions air from the material holding mechanism 2 toward the air collection box 32, which can achieve a certain degree of negative pressure in the cavity of the material holding mechanism 2.

[0034] Furthermore, the intake fan 34 is an axial flow fan, which is existing technology and will not be described in detail here.

[0035] The design is further optimized so that the ventilation assembly includes several ventilation sections connected end-to-end; the first and last ventilation sections are not connected, forming a cylindrical ventilation assembly; each ventilation section includes a ventilation cylinder 35 and a square baffle 36; a ventilation shaft 37 is installed inside the ventilation cylinder 35; two adjacent ventilation shafts 37 at the top are rotatably connected at one end; one side of the square baffle 36 passes through the axis of the ventilation shaft 37 and is fixedly connected to the ventilation shaft 37; the square baffle 36... The opposite sides are respectively adapted to and slidably contact the inner side wall of the air exchange cylinder 35; a semi-circular baffle 38 is fixedly connected to the bottom end of the air exchange shaft 37; the circumferential side of the semi-circular baffle 38 is slidably contacted to the inner side wall of the air exchange cylinder 35; a distribution pipe 33 is fixedly connected and connected to the side wall of the air exchange cylinder 35; two adjacent air exchange cylinders 35 are rotatably connected to each other; a return air box 39 is fixedly connected and connected to the bottom surface of the air exchange cylinder 35 located at the bottom end; the bottom surface of the return air box 39 is fixedly connected and connected to the material holding mechanism 2.

[0036] Furthermore, the top and bottom surfaces of adjacent square baffles 36 are fitted together.

[0037] Furthermore, in order to enable the adjacent ventilation sections to rotate and connect, the sizes of the adjacent ventilation sections are somewhat different, but their structures are exactly the same.

[0038] Furthermore, a sealed bearing is fitted and fixed to the outer side of one of the two adjacent air exchange cylinders 35; the outer side of the sealed bearing is interference-fitted with the inner cavity sidewall of the other air exchange cylinder 35, thereby realizing the rotatable connection between the two adjacent air exchange cylinders 35, that is, realizing the rotatable connection between adjacent air exchange sections.

[0039] To further optimize the design, a return air box 39 is provided to divert the extracted gas from the ventilation assembly. The return air box 39 is a hollow cylindrical structure with an open top. An air inlet pipe 6 is rotatably connected to the bottom of the return air box 39. The air inlet pipe 6 is fixedly connected to and communicates with the material holding mechanism 2. The top of the return air box 39 is rotatably connected to the ventilation joint located at the lowest end. A semi-circular arc plate 7 is fixedly connected to the top surface of the return air box 39. The circumferential side of the semi-circular arc plate 7 is fixedly connected to the inner wall of the return air box 39, which can prevent the backflow of gas. A ventilation shaft 37 is rotatably connected to the center of the semi-circular arc plate 7 with damping. The top of the return air box 39 is rotatably connected to the bottom of the ventilation cylinder 35.

[0040] Furthermore, the intake pipe 6 is rotatably and sealed to the bottom of the return air box 39 to prevent air leakage at the connection between the intake pipe 6 and the return air box 39.

[0041] Furthermore, the semi-circular baffle 7 is located on the side of the square baffle 36 of the bottom air vent that is away from the semi-circular baffle 38.

[0042] The design is further optimized. The suction assembly includes a suction conduit 41, a ball valve 42, and a handheld conduit 43. One end of the suction conduit 41 passes through the material holding mechanism 2, and the other end is fixedly connected to and communicates with the ball valve 42. One end of the handheld conduit 43 is fixedly connected to and communicates with the ball valve 42, and the other end is fixedly connected to and communicates with the suction head 82. The outer side of the handheld conduit 43 is engaged with the top of the suction head 82. The suction head 82 can be moved by the handheld conduit 43 to draw liquid.

[0043] Furthermore, a slot is provided at the top of the suction head 82; the handheld tube 43 can be engaged with the suction head 82 through the slot.

[0044] Further optimization of the design: the suction head 82 is a hollow spherical structure; several suction holes 5 are opened on the side of the suction head 82. Setting the suction head 82 as a spherical shape can avoid the existing sharp suction head 82 from scratching the patient's internal organs.

[0045] The solution is further optimized. The material holding mechanism 2 includes a sealing cover 21 and a collection bucket 22. The side of the sealing cover 21 is fixedly connected to one end of the suction pipe 41 and one end of the air inlet pipe 6, respectively, and is connected to them. The bottom end of the sealing cover 21 is screwed to the top end of the collection bucket 22.

[0046] Further optimization of the design involves rounding the edges of several suction holes 5 to prevent the sharp edges of the suction holes 5 from injuring internal organs.

[0047] The design is further optimized by using a stainless steel suction tube 41, which facilitates the suction of fluid from the human body's internal organs into the collection bucket 22. One end of the suction tube 41 is located inside the collection bucket 22 and faces the bottom of the collection bucket 22. The handheld tube 43 is a silicone flexible tube, which is convenient for handheld operation.

[0048] The working process of this embodiment is as follows:

[0049] When fluid needs to be aspirated from internal organs during surgery, the suction head 82 is moved to the target position by holding the hand-held tubing 43, and the suction machine 34 is turned on. The suction machine 34 draws air from the inner cavity of the material receiving mechanism 2 through the air outlet pipe 31 and sends it to the air collection box 32. The air collection box 32 then divides the air into several portions through several air distribution pipes 33 and introduces them into several ventilation sections. At this time, the ventilation cylinder 35 is rotated. Because the connection port between the ventilation cylinder 35 and the air distribution pipe 33 is located above the semi-circular baffle 38, rotating the ventilation cylinder 35 can move the connection port to the other side of the square baffle 36, thereby changing the direction of airflow. The specific method is as follows:

[0050] Preferably, there are 3 air distribution pipes 33, which means there are also 3 air exchange nodes;

[0051] When it is necessary to aspirate bodily fluids from a patient, if full suction is required, the three connecting ports are adjusted to the side of the square baffle 36 away from the semicircular baffle 38, with the three semicircular baffles 38 respectively positioned on the same side of the square baffle 36. At this time, all the aspirated airflow is discharged to the external atmosphere through several ventilation cylinders 35, achieving maximum suction of air from the inner cavity of the material container 2. Then, the ball valve 42 is opened, and the bodily fluids enter the handheld tube 43 and the suction tube 41 sequentially through the suction hole 5 on the suction head 82, and finally enter the collection bucket 22.

[0052] Example 2:

[0053] like Figure 5As shown, when people need to reduce the negative pressure by two levels, they rotate the return air box 39 to align the semi-circular arc plate 7 and the semi-circular baffle plate 38 vertically, rotate the top air exchange cylinder 35 by 180°, and connect the top air distribution pipe 33 to the outside atmosphere. The two bottom air distribution pipes 33 are connected to the inner cavity of the material holding mechanism 2 through the return air box 39, thus reducing the suction power of the present invention by two levels.

[0054] Example 3:

[0055] like Figure 4 As shown, when people need to reduce the negative pressure by one level, they rotate the return air box 39 to align the semicircular baffle 7 and the semicircular baffle 38 vertically. The top semicircular baffle 38 and the two semicircular baffles 38 below it are set in opposite directions, and the semicircular baffle 7 and the bottom semicircular baffle 38 are set in a corresponding manner, thus reducing the suction force of the present invention by one level.
