摘要
A vitrectomy instrument and a system including the same are disclosed herein. The vitrectomy instrument includes a handpiece having an outer tube and an inner tube coaxially disposed in the outer tube, the inner tube being slidably displaceable relative to the outer tube; a cutting power generator operatively coupled to the inner tube, the cutting power generator configured to reciprocably drive the inner tube for shearing tissue and/or vitreous; and an ultrasonic generator operatively coupled to the inner tube, the ultrasonic generator configured to vibrate the inner tube for vibratory fragmentation and/or cutting of the tissue and/or the vitreous. The vitrectomy system may include the vitrectomy instrument together with a support sleeve for supporting the vitrectomy instrument to provide increased rigidity to the needle of the vitrectomy instrument.
