Abstract
This invention is directed to devices and methods for stereotactic access, and particularly to a frameless stereotactic access device for accessing a body cavity and methods therefor. In general, a stereotactic device may include portions or features for fixing the device to a portion of a patient's body, such as, for example, a skull, such that the device may be generally spatially fixed in relation to the patient's body or part thereof. The stereotactic device may also generally include portions or features for guiding a medical device or other device at a particular trajectory in relation to the patient's body or part thereof.
Claims20
A stereotactic access device for use with a patient, comprising:
- a frame body having a plurality of mounting ends, each mounting end configured to be secured to the patient;
- a cover body attachable and detachable to the frame body;
- and
- a mounting guide having a guide channel, the mounting guide retained by the cover body;
- wherein when the cover body is attached to the frame, a space is provided between the mounting guide and the patient.
A stereotactic access device for use with a patient, comprising:
- a frame body defining an opening and having a plurality of mounting ends, at least one of the mounting ends configured to receive a securing device to secure the frame body to the patient;
- a cover body attachable and detachable to the frame body, the cover body covering at least a portion of the opening defined by the frame body;
- and
- a movable guide movably attached to the cover body, the movable guide defining a movable guide channel;
- wherein the movable guide is spaced from the patient when the cover body is attached to the frame body.
A method for stereotactic access to a patient, comprising:
- positioning a stereotactic access device having a frame body and a detachable first cover body relative to the patient;
- securing the stereotactic access device to the patient;
- removing the first cover body from the frame body;
- sterilizing the frame body secured to the patient;
- attaching a second sterile cover body to the frame body;
- and
- aligning a guide channel in the second sterile cover body to a desired trajectory.
