The term "suction" in surgical terminology specifically refers to the evacuation of fluids from the surgical site. This process is crucial for maintaining a clear view of the operative field, enhancing visibility for the surgeon, and minimizing fluid accumulation that can interfere with the procedure. During surgical operations, suction devices are used to remove blood, saline, and other bodily fluids to promote a clean and manageable environment, thereby facilitating the steps of the surgery.

Other concepts, such as the removal of gas or the application of force, do not encompass the primary function of suction in a surgical context. While inserting catheters is an essential task in various procedures, it is distinct from the action of suctioning, which directly involves the removal of unwanted fluids rather than a method of introducing or manipulating instruments. Therefore, the definition related to the evacuation of fluids aligns with the purpose and utility of suction in a surgical setting.
