Technical Field

[0001] The utility model relates to the technical field of aspirators, in particular to a continuous aspirator for thoracoscopic surgery. Background Art

[0002] The aspirator is used to remove bleeding, exudate, pus, and contents of chest organs during surgery to make the operation clear and reduce the chance of contamination. The principle of the aspirator is very simple, which is to create a negative pressure state of its suction head through a certain method, so that the atmospheric pressure will squeeze the substances outside the suction head into the suction head, thereby achieving the "suction" effect.

[0003] When using the existing device, a hose-like suction device is usually inserted into the patient's chest cavity to perform intraoperative fluid suction operations. However, during this process, there is often a narrow space between the patient's chest organs and flesh. The suction heads and calibers of the existing suction devices are uniform in size and caliber, and it is difficult to avoid suctioning fluid in a narrow space. After the tiny suction head has sucked the fluid, it needs to return to its original position. Therefore, a continuous suction device for thoracoscopic surgery that solves the above problem is needed. Utility Model Content
