摘要： A transparent illuminated infusion cannula is provided for illuminating an area during eye surgery. An optical fiber may be spaced a certain distance away from the cannula such that fluid flow around the distal end of the fiber and into the transparent cannula may occur with a much higher flow rate than what had previously been possible. The fiber cannula airspace may be optimized so that the cross-sectional area of the fluid conduit remains substantially constant in order to achieve a best compromise between high light transmittance and high fluid flow rate.

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 system and minimally invasive method for the placement of pedicle screws without the use of a trocar needle and/or guidewires. The system and method comprises at least one pedicle finder and at least one dilator. The pedicle finder preferably comprises an extender that is removably attached to a pedicle anchor. Attached to a pedicle anchor is a flexible tether. The extender preferably includes a passage through which the flexible tether extends. The dilator comprises a tubular body with two ends, where a first end comprises a means for securing the dilator into bony process of vertebra and a second end comprises at least two arm attachments. The tubular body Of the dilator is configured to slide easily over an extender and secure the first end into bony vertebra to prevent the dilator from dislodging. The arm attachment of the second end of the dilator can be interconnected with another arm attachment via a linking element and/or the dilator can be secured to a stable object such as a table via a securing element.
