1. An arthroscopic surgical instrument comprising:

  • a) a hollow tube having a proximal and a distal end;

    b) end effector means of a first strength coupled to said distal end of said hollow tube;

    c) actuating means for actuating said end effector means, said actuating means coupled to said proximal end of said hollow tube;

    d) connector means for coupling said end effector means with said actuating means such that actuation of said actuating means results in movement of said end effector means, said connector means including a substantially cylindrical push rod having a flattened plate-like frangible link portion having at least two opposite flat substantially parallel surfaces, and coupling means of a second strength for coupling said push rod to said end effector means, wherein said frangible link has a third strength which is weaker than said first and second strengths, such that application of a force applied to said end effector means by said actuating means via said connector means causes said frangible link portion of said push rod to break prior to one of said end effector means and said coupling means breaking.
