摘要： A microsurgical probe tip and method of using same are disclosed. One embodiment of the microsurgical probe tip comprises: an outer cutting member, comprising a first tube having a wall, a closed end and a port formed in the wall near the closed end; an inner cutting member, comprising a second tube coaxial with and operable to move in a reciprocating motion within the first tube and having a first end operable to be coupled to a driving mechanism and a second end with a cutting edge for cutting tissue; a first alignment mark on the outer cutting member at a first predetermined position adjacent to the port; and a second alignment mark on the inner cutting member at a second predetermined position adjacent to the cutting edge of the inner cutting member, wherein the second alignment mark is visible through the port and operable to be aligned with the first alignment mark such that when the first and second alignment marks are aligned, a preferred relative positioning between the inner and outer cutting members is achieved. The microsurgical probe tip can further comprise one or more radial alignment marks on the inner cutting member, wherein the radial alignment marks are parallel to one another at fixed intervals from one another and positioned so that one or more of the radial alignment marks are visible through the port so as to indicate the relative lateral positioning between the inner cutting member and the outer cutting member. The radial alignment marks can be made by a method, or combination of methods, such as laser cutting, inkjet printing, and mechanical scribing. The driving mechanism can be a pneumatic driving mechanism, an electro-mechanical driving mechanism, and/or a magnetic driving mechanism. The microsurgical probe tip can further comprising a plurality of gauge marks on an outer surface of the outer cutting member, wherein the gauge marks are parallel to one another at a fixed interval (e.g., 1 millimeter) from one another and positioned so that the gauge marks can be used as a measuring tool in a surgical environment

摘要： A syringe-like device having a chamber in which a pressurizing piston reciprocates. The chamber is connected on one end to a vial containing a drug to be delivered to an eye and on the other end to a needle or cannula for administering the drug to an eye. Pulling proximally backwards on the piston creates a vacuum in the chamber and draws the drug out of the vial. Upon release of the piston, a spring pushes the piston forward, pressurizing the chamber and forcing the drug out of the cannula. A one-way valve prevents the drug from being expelled back into the vial. A pinch valve between the chamber and the cannula allows the flow of the drug out of the cannula to be stopped. The flow rate of the drug out of the cannula can be controlled by varying the size of the chamber, piston and spring.
