K-wire and method for surgical procedures

摘要

A surgical guide wire or K-wire and method of use are provided. The K-wire or guide wire has opposite end portions and a shank portion in between. One end portion has a deformable end portion that, once outside of a confining guide passage, can be deformed to present a projected forward facing area that is larger than the transverse cross section of the K-wire or guide wire while in the passage. The increased area will provide increased resistance to additional forward axial movement into the surgical site.

1. A method of conducting a medical procedure using a guide wire, the method including: placing a surgical tool end at a surgical site, said surgical tool having a guiding through bore opening at the tool end; guiding a guide wire to the site by passing the guide wire through the passage, said guide wire having an operative end portion; and deforming a portion of the operative end portion after its exit from the passage such that the deformed portion presents a projected area greater than the cross sectional area of the guide wire when in the passage, wherein said operative end portion comprising a first independent deformable leg and a second independent deformable leg, each said independent deformable leg diverging from a common area of said guide wire, said independent deformable legs predisposed to move in an outward direction with respect to each other and forming a first gap extending the length of said independent deformable legs; one independent deformable leg being longer than said second independent deformable leg, said longer independent deformable leg including a tip portion that is constructed to overlap a tip portion of the said shorter independent deformable leg and forming a second gap between said tip portions, said second gap formed generally perpendicular to the guide wire longitudinal axis when in the non-deformed state, wherein each said opposing deformable legs contains a bend positioned distally from the point where said opposing independent deformable leg diverge from said common area of said guide wire, wherein at least one independent deformable leg contains a groove sized to receive a projection and said opposite independent deformable leg contains a projection sized and shaped to fit within said groove.
