摘要:
In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.
