摘要：
In various embodiments, aspiration tubing connecting ahandpiece to a surgical console may include a high compliant section, atransition section, and a low compliant section. In some embodiments, thehigh compliant section may have a lower durometer and/or different geometrythan the low compliant section. The transition section may take a numberof forms, including a connector or a continuous section of tubing thatgradually increases in durometer and/or changes geometry through thelength of the tubing. In the various embodiments, the high compliant sectionmay provide flexibility near the handpiece to make the handpiece easierto hold and maneuver while the low compliant section may reduce theeffects of occlusion break surge. In some embodiments, the high compliantsection may include, for example, ribs, stiffening rings, a stiffening sleeve,or a stiffening sock to increase the stiffness of the high compliant section.
