Abstract
The present application describes various embodiments of guides that are designed in accordance with one or more anatomical landmarks near an operated bone (or portion thereof). In aspects, at least a portion of a guide is designed to conform to the shape of one or more anatomical landmarks in order to attach (or latch) the guide to at least one of the one or more anatomical landmarks. In aspects, the contact surface (or inner contour) of a guide may also be designed to follow at least a portion of the contour of the operated bone. The landmark-conforming and/or contour-following design of the guide may assist surgeons in the placement of the guide.
Claims20
A surgical cutting guide, comprising:
- a contact surface having a contour that matches a reverse contour of a biological structure, wherein the biological structure includes a bone having a length, a width, and a thickness, wherein the thickness is less than the length and the width;
- a longitudinal axis extending between a proximal end and a distal end;
- an extension portion at the distal end, the extension portion comprising a hook extending along the longitudinal axis, the hook configured to extend around an edge of an anatomical landmark on the biological structure, the hook having a hook width sized to extend around the thickness of the bone at the edge of the anatomical landmark so as to latch the surgical cutting guide onto the anatomical landmark with a remainder of the guide extending along the reverse contour of the biological structure away from the anatomical landmark;
- one or more apertures defined on the surgical cutting guide;
- and
- a cutting slot extending from the proximal end to the distal end.
A medical apparatus, comprising:
- a cutting guide three-dimensionally (3D) printed based on an anatomical landmark positioned near a biological structure that is to be operated, the biological structure including a bone having a length, a width, and a thickness, wherein the thickness is less than the length and the width, wherein the cutting guide comprises:
- a contact surface having a contour that matches at least some of a reverse contour of the biological structure;
- a longitudinal axis extending between a proximal end and a distal end;
- an extension portion at the distal end, the extension portion comprising a hook extending along the longitudinal axis, the hook configured to extend around an edge of the anatomical landmark on the biological structure, the hook having a hook width sized to extend around the thickness of the bone at the edge of the anatomical landmark so as to latch the surgical cutting guide onto the anatomical landmark with a remainder of the guide extending along the reverse contour of the biological structure away from the anatomical landmark;
- one or more apertures defined on the surgical cutting guide;
- and a cutting slot extending from the proximal end to the distal end.
A surgical cutting guide, comprising:
- a contact surface having a contour that matches a reverse contour of a maxilla bone;
- a longitudinal axis extending between a proximal end and a distal end;
- an extension portion at the distal end, the extension portion comprising a hook extending along the longitudinal axis, the hook configured to extend around an edge of a nasal aperture near the maxilla bone, the hook having a width sized to extend around a thickness of the maxilla bone at the edge of the nasal aperture to latch the surgical cutting guide onto the nasal aperture with a remainder of the guide extending along the reverse contour of the maxilla bone away from the nasal aperture;
- one or more apertures defined on the surgical cutting guide;
- and a cutting slot extending from the proximal end to the distal end.
