Abstract

Orthopedic implant insertion instruments for precision guiding of a fracture fixation implant into fractured bone to promote healing are disclosed. The implant insertion instruments comprise an insertion handle for implantation of a first fixation implant, an aiming arm for precise guiding of a second fixation implant into bone, a guide sleeve for protection of soft tissue and for translational and rotational control of the second fixation implant, and a drive shaft with coupling screw for attachment to the second fixation implant and for driving the second fixation element through the aiming arm and guide sleeve into the fractured bone. The implant insertion instruments also include a soft tissue clearance device to aid the surgeon in inserting the first fixation implant into the fractured bone. Also disclosed is a measuring device that reduces measuring errors made by a user and a measuring device that determines implant length, diameter, and angle of insertion.

Dependent claims

An orthopedic implant insertion assembly for inserting an implant, comprising:

a handle member having an arcuate body extending from a first end to a second end, the first end of the handle configured and designed to couple to the implant;
an arm member having a longitudinal axis extending between first and second ends of the arm member, the first end of the arm member having an attachment member configured and designed to couple to the second end of the handle member and the second end of the arm member having a sleeve retaining portion wherein the sleeve retaining portion has a channel that forms a non-straight angle with respect to the longitudinal axis;
and
a nut member having a bore extending therethrough along a bore axis, the nut being structured for coupling to an insertion instrument so that the bore axis is aligned with the channel permitting an item inserted through the bore to pass through the channel to a desired location on the implant coupled to the handle, the nut having a flange member configured and dimensioned to be received in a corresponding recess of the arm member so that the nut member is rotatably coupled to the sleeve retaining portion of the arm member.
