Abstract
A surgical blade adapted to be typically used in medical procedures is disclosed. The blade is provided with markings located near the cutting edge. The markings are configured to be indicative of the depth of the blade and/or of the cutting edge during the incision of an organic tissue. The markings are configured to substantially follow the shape of the cutting edge such as to indicate the depth of the blade substantially independently of the orientation thereof.
Claims34
A surgical blade, said blade being substantially planar and comprising two sides and a cutting edge, at least one of said sides comprising markings substantially following said cutting edge, said markings being configured to provide a substantially constant indication of a selected depth of said cutting edge with respect to a tissue when an orientation of said blade with respect to said tissue is changed.
A surgical blade, said blade being substantially planar and comprising a first surface, a second surface, and a substantially curved cutting edge, wherein at least one of said first and second surfaces comprises markings substantially parallel to said cutting edge, said markings being configured to provide a substantially constant indication of a depth of said cutting edge with respect to a tissue when an orientation of said blade with respect to said tissue is changed.
A surgical blade in combination with a handling tool, said handling tool having a handling portion and a mounting portion extending at an extremity of said handling portion, said blade being mounted to said mounting portion, said blade being substantially planar and comprising a first surface and a second surface, and a substantially curved cutting edge, wherein at least one of said first and second surfaces comprises markings substantially parallel to said cutting edge such that said markings provide a substantially constant indication of a depth of said cutting edge with respect to a tissue when an orientation of said blade with respect to said tissue is changed.
A surgical blade, said blade being substantially planar and comprising two sides and a cutting edge, at least one of said sides comprising at least one marking substantially following said cutting edge, said at least one marking being configured to provide a substantially constant indication of a selected depth of said cutting edge with respect to a tissue when an orientation of said blade with respect to said tissue is changed.
A surgical blade, said blade being substantially planar and comprising a first surface, a second surface, and a substantially curved cutting edge, wherein at least one of said first and second surfaces comprises at least one marking substantially parallel to said cutting edge, said at least one marking being configured to provide a substantially constant indication of a depth of said cutting edge with respect to a tissue when an orientation of said blade with respect to said tissue is changed.
A surgical blade in combination with a handling tool, said handling tool having a handling portion and a mounting portion extending at an extremity of said handling portion, said blade being mounted to said mounting portion, said blade being substantially planar and comprising a first surface, a second surface, and a substantially curved cutting edge, wherein at least one of said first and second surfaces comprises at least one marking substantially parallel to said cutting edge such that said at least one marking provides a substantially constant indication of a depth of said cutting edge with respect to a tissue when an orientation of said blade with respect to said tissue is changed.
