A surgical blade package facilitates the mounting of a surgical
blade on to the forwardly-projecting cleat on a scalpel handle;
and following use in the O.R., the surgical blade package facilitates
stripping the used blade off the scalpel for disposal in a sharps
container. The cleat is inserted beneath the rear end portion of
the blade, and between the blade and the bottom wall of the blade
package; and forward and upward movement of the scalpel snaps the
blade on to the scalpel in a continuous movement. The opposite procedure
is used to demount the used blade from the scalpel and encase it
in the original blade package for disposal in a sharps container.
A surgical blade is disclosed for use with a surgical tool for
making incisions in the sclera of an eye to form a scleral pocket
to receive a scleral prosthesis. The surgical blade comprises a
rotatable support arm capable of being rotated by the surgical tool
and a detachable curved cutting blade for making incisions in the
sclera of an eye. The surgical tool causes the curved cutting blade
to advance through the sclera to form an incision having dimensions
to receive a scleral prosthesis. When the incision is complete the
curved cutting blade is detached from the rotatable support arm.
The curved cutting blade is then removed from the incision by pulling
the curved cutting blade forward out of the incision. The incision
has the exact dimensions to receive a scleral prosthesis.

An ultrasonic surgical blade includes an ultrasonic-surgical-blade
body having a longitudinal axis, a distal tip, a proximal end adapted
for longitudinal ultrasonic vibrational excitation, a most-distal
longitudinal vibration node, a treatment portion extending from
the distal tip toward the most-distal longitudinal vibration node,
and a functional asymmetry. The functional asymmetry is asymmetric
about the longitudinal axis and translates longitudinal ultrasonic
vibrational movement of the proximal end into a combination of a
longitudinal ultrasonic vibration and a transverse ultrasonic vibration
in at least some of the treatment portion of the ultrasonic-surgical-blade
body. An amplitude of the transverse ultrasonic vibration at the
distal tip is less than substantially ten percent of a maximum amplitude
of the transverse ultrasonic vibration of the treatment portion
of the ultrasonic-surgical-blade body. An alternate embodiment of
the ultrasonic surgical blade includes at least one functional asymmetry
and at least one balance asymmetry.
