They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the invention.

[0024] In the description of the invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "installed," "connected," etc. should be understood broadly. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] This invention provides a replaceable head aspirator. Through the provision of a flexible adsorption portion 1, it achieves blood adsorption while maintaining tissue traction. Combined with a modular connection structure, it allows for rapid intraoperative replacement. Its core innovations lie in: 1) the use of a flexible, porous adsorption portion 1 to replace the traditional rigid head; 2) a unique quick-connection structure that enables instant intraoperative replacement.

[0026] like Figure 1-2 The figure shows a specific embodiment of a suction device with a replaceable head. This embodiment is a surgical suction device with a replaceable adsorption part 1, comprising:

[0027] The main body of the suction device is provided with a through suction channel inside;

[0028] The adsorption part 1 has an adsorption function and is detachably connected to the distal end of the aspirator body;

[0029] The connection structure is provided at the junction of the adsorption part 1 and the main body of the aspirator to achieve quick disassembly and assembly;

[0030] The operating handle 4 is connected to the proximal end of the suction device body, and a negative pressure tube interface is provided at the tail of the handle.

[0031] The adsorption part 1 is flexible and has multiple holes. The adsorption part 1 can be any one of a cotton head, a sponge head, and a non-woven fabric head.

[0032] The suction unit 1 is connected to the suction device body via an intermediate connector, which is a plastic rod 2 with a lateral suction hole.
