Kit for implanting heat deformable fixation elements of different sizes

摘要

A device for implanting heat deformable fixation elements of different sizes in a bone, comprises a hand piece extending from a proximal end to a distal end and including an internal optical waveguide connected to a laser source and open to the distal end of the hand piece and a light guiding tip extending from a proximal end to a distal end, the proximal end of the light guiding tip being removably mechanically and optically connectable to the distal end of the hand piece and the distal end of the light guiding tip being configured to permit removable attachment of a bone fixation element, the light guiding tip including an optical waveguide, wherein the light guiding tip is configured to control a total radiant energy Q transmitted from the laser source to the bone fixation element.

主权项

1. A device for implanting at least one bone fixation element in a bone, comprising:
a bone fixation element comprising thermoplastic material and defining a proximal surface area at a proximal portion thereof; a hand piece that defines a proximal end and a distal end opposite the proximal end, the hand piece including a laser source configured to emit a radiant flux φ1 and the hand piece further including a first internal optical waveguide connected to the laser source and open at the distal end of the hand piece; and a light guiding tip having a proximal end and a distal end opposite the proximal end, the light guiding tip including a second optical waveguide, the proximal end of the light guiding tip being configured to mechanically, optically and removably connect to the distal end of the hand piece, and the distal end of the light guiding tip being configured to permit removable attachment of the bone fixation element thereonto, and a controller configured to recognize the light guiding tip connected to the hand piece and in response to automatically adjust a total radiant energy Q transmitted from the laser source to the bone fixation element based on the light guiding tip connected to the hand piece and the proximal surface area of the bone fixation element.
