Abstract
A trajectory frame for use with an MRI-guided interventional system includes a base having a patient access aperture formed therein. The base is configured to be secured to the body of a patient. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis. An elongated guide is secured to the platform and includes opposite proximal and distal end portions and a bore that extends from the proximal end portion to the distal end portion. The guide distal end portion is positioned proximate the patient access aperture. The guide is configured to removably receive various devices therein for quick release therefrom, including a targeting cannula, drill guide and drill bit, skull fixation device and driver, and catheter guide.
Claims15
A trajectory frame for use with an MRI-guided interventional system, comprising:
- a base having a patient access aperture formed therein, wherein the base is configured to be secured to the body of a patient;
- a yoke movably mounted to the base and rotatable about a roll axis;
- a platform movably mounted to the yoke and rotatable about a pitch axis;
- an elongated guide support secured to the platform, wherein the guide support comprises opposite proximal and distal end portions, wherein the guide support distal end portion is positioned proximate the patient access aperture, wherein the guide support comprises a bore therethrough that extends from the proximal end portion to the distal end portion;
- and
- a first device guide and a second different device guide releasably and separately positionable within the bore of the guide support such that a respective distal end of each is positioned proximate the patient access aperture, wherein the first device guide, when separately positioned within the bore of the guide support, is removably secured directly to the guide support, and wherein the second device guide, when separately positioned within the bore of the guide support, is removably secured directly to the guide support;
- wherein a proximal end of the first device guide and/or the second device guide comprises a cap configured to be removably secured to the guide support proximal end portion, wherein the cap comprises an opening to facilitate insertion of a device therethrough.
An MRI-guided medical assembly, comprising:
- a trajectory frame, comprising:
- a base having a patient access aperture formed therein, wherein the base is configured to be secured to the body of a patient;
- a yoke movably mounted to the base and rotatable about a roll axis;
- and
- a platform movably mounted to the yoke and rotatable about a pitch axis;
- and
- an elongated guide support secured to the platform, wherein the guide support comprises opposite proximal and distal end portions, wherein the guide support distal end portion is positioned proximate the patient access aperture, wherein the guide support comprises a bore therethrough that extends from the proximal end portion to the distal end portion;
- and
- a targeting cannula and a drill guide releasably and serially inserted within the bore;
- wherein the targeting cannula comprises an axially extending open lumen having an internal diameter that is different from an internal diameter of an axially extending open lumen of the drill guide, wherein the targeting cannula and drill guide each comprise respective opposite proximal and distal end portions, wherein the respective distal end portions of the targeting cannula and drill guide are separately positionable within the bore proximate the patient access aperture, and wherein the respective proximal end portions of the targeting cannula and drill guide are removably and separately secured directly to the guide support proximal end portion for quick release therefrom;
- and
- wherein the proximal end portion of the drill guide comprises a cap configured to be removably secured to the guide support proximal end portion, wherein the cap comprises an opening to facilitate insertion of a device through the drill guide.
