ABSTRACT:
A cutting instrument is provided, particularly applicable to vitreous surgery, having an elongated, tubular housing formed with a cutting orifice near its end. A resilient, inner tubular member is slidably mounted coaxially within the tubular housing. The tubular housing is bent in a manner to displace the cutting orifice in a direction toward the resilient, inner tubular member. As the end of the resilient, inner tubular member passes across the cutting orifice, it is resiliently urged into shearing contact with the cutting orifice.
