Abstract: A vitrectomy probe with combined vibration dampening and attenuating. The probe may include a variety of features to lessen the vibrations felt by a surgeon during a vitrectomy procedure. These may include minimizing the degree of flow restriction through a housing that facilitates cutter reciprocation by way of air pressure. Further, utilizing softer stops at a diaphragm that drives the cutter reciprocation may be of benefit as is strategically lessening compressive forces by seals at an extension tube coupled to the diaphragm where possible. The use of a softer gripping component that is actually held by the surgeon may be of benefit in terms of vibration attenuation.
