Abstract
An anisotropic surgical instrument is provided having at least one reinforced region that includes at least one reinforcement fiber oriented along a direction that corresponds to a direction of the force applied to the surgical instrument during use. The instrument can further include a weakened region that defines a hinge about which the instrument can iterate between a contracted configuration and an expanded configuration. Methods of fabricating such instruments are also described.
Claims20
An anisotropic surgical instrument comprising:
- a first reinforced region including a first at least one reinforcement strand that is embedded in a solidified polymer,
- a weakened region that includes the solidified polymer and one of:
- i) none of the first plurality of strands embedded in the solidified polymer;
- and
- ii) a density of the first plurality of strands less than that of the first reinforced region.
2 more elements
An anisotropic surgical instrument comprising:
- a shaft that extends along a central axis, from a proximal end to a distal end, and a head that extends from the distal end,
- wherein at least a portion of the shaft includes a solidified polymer and at least one reinforcement strands that is embedded in the solidified polymer and oriented substantially helically about the central axis, and
- wherein the shaft is configured to rotate such that the head transmits a torsional force.
