at least a portion of the staple rod is adapted to move parallel to the longitudinal axis at a first period of time in response to a trigger actuation; and
at least a portion of the stapling mechanism is adapted to move substantially parallel to the longitudinal axis at a second period of time in response to the trigger actuation, the second period of time different from the first period of time.
5. The medical device of claim 1 , wherein:
the second one of the plurality of telescoping sections comprises at least one extended hook section for engaging the first notch of the first one of the plurality of telescoping sections; and
the first notch comprises a notch lip.
6. The medical device of claim 1 , further comprising:
a cutting mechanism and a stapling mechanism, the stapling mechanism having a staple and a staple rod.
7. The medical device of claim 6 , wherein:
the staple rod is adapted to move the cutting mechanism.
8. The medical device of claim 7 , wherein:
the stapling mechanism further comprises at least one staple pusher; and
the staple rod is adapted to move the at least one staple pusher prior to moving the cutting mechanism.
9. The medical device of claim 6 , wherein:
the stapling mechanism comprises a stapling shaft, at least a portion of the stapling shaft slidable positioned in a second notch in the first one of the plurality of telescoping sections.
10. A surgical stapler comprising:
a plurality of telescoping sections; and
an outer sheath at least partially encapsulating the plurality of telescoping sections, the outer sheath configured to prevent buckling of the plurality of telescoping sections; wherein
a first one of the plurality of telescoping sections has a first notch,
a second one of the plurality of telescoping sections has a head portion,
the first notch of the first one of the plurality of telescoping sections is configured to slidably receive at least a portion of the head portion of the second one of the plurality of telescoping sections, and
the first one and the second one of the plurality of telescoping sections are slidable relative to each other between an extended setting and a retracted setting.
11. The surgical stapler of claim 10 , wherein the surgical stapler is a pediatric laparoscopic surgical stapler.
12. The surgical stapler of claim 10 , wherein:
the second one of the plurality of telescoping sections comprises at least one extended hook section for engaging the first notch of the first one of the plurality of telescoping sections; and
the first notch comprises a notch lip.
13. The surgical stapler of claim 10 , further comprising:
a cutting mechanism and a stapling mechanism, the stapling mechanism having a staple and a staple rod.
14. The surgical stapler of claim 13 , wherein:
the staple rod is adapted to move the cutting mechanism.
15. The surgical stapler of claim 14 , wherein:
the stapling mechanism further comprises at least one staple pusher; and
the staple rod is adapted to move the at least one staple pusher prior to moving the cutting mechanism.
16. The surgical stapler of claim 13 , wherein:
the stapling mechanism comprises a stapling shaft, at least a portion of the stapling shaft slidable positioned in a second notch in the first one of the plurality of telescoping sections.
17. A method of manufacturing a medical device, comprising:
providing an outer sheath;
providing a plurality of telescoping sections, a first one of the plurality of telescoping sections having a first notch, a second one of the plurality of telescoping sections having a head portion, the first notch of the first one of the plurality of telescoping sections shaped to slidably receive at least a portion of the head portion of the second one of the plurality of telescoping sections,
at least partially encapsulating the plurality of telescoping sections with the outer sheath to prevent buckling of the plurality of telescoping sections, such that the first one and the second one of the plurality of telescoping sections are slidable relative to each other between an extended setting and a retracted setting.
18. The method of claim 17 , further comprising:
providing a stapling mechanism having at least one staple and a staple rod; and wherein
