Abstract
A tool and method for locating a proper position for a portal incision for hip arthroplasty, the tool being a tubular body having a first portion defining a first axis, a second portion defining a second axis non-parallel to the first axis, the second portion having a directional tool and a lead coaxially aligned, wherein when the tubular body is placed adjacent to an acetabulum with the directional tool aimed at the acetabulum and perpendicular to a plane of the face of the acetabulum, the lead points to location on the skin that would be the proper location for the portal incision. The lead may have a blunt tip, a cutting instrument, or an opening through which a flexible tool can be inserted to forge a path towards the proper location for the portal incision.
Claims7
A tubular body for locating an optimal position for a portal incision in a hip arthroplasty in a patient, comprising:
- a first portion defining a first axis, the first portion having a first opening;
- a second portion, the second portion, comprising:
- a lead having a second opening in fluid communication with the first opening;
- and
- a directional tool, the directional tool connected to a leading end of the first portion, wherein the lead and the directional tool are coaxially aligned to define a second axis, wherein the first axis and the second axis are non-parallel;
- a flexible tool inserted through the first opening, a leading end of the flexible tool exiting the second opening, the leading end comprising a cutting instrument, the leading end extendable away from the second opening for use in advancing the leading end through non-critical tissues of said patient to create a path toward an optimal position for a portal incision.
