Abstract
A trajectory guide for providing access to a target site of a living subject along a desired path comprises a baseplate including a clamp lock, a guide member at least partially contained within the baseplate and having a channel therein, a plurality of adjustable legs each including a first end and a second end, wherein the first end is coupled to the baseplate, and a leg lock coupled to each adjustable leg and moveable between an unlocked position and a locked position in order to set a desired length of the adjustable leg, wherein the adjustable legs and the guide member are structured to be adjusted to provide an infinite number of trajectories in three-dimensional space extending through the channel in the guide member toward a target.
Claims22
A trajectory guide comprising:
- a guide member;
- an assembly configured to hold the guide member such that the guide member pivots and rotates with respect to the assembly to obtain a plurality of pivot and rotation alignments between the guide member and the assembly;
- a lock coupled to the assembly configured to lock the guide member in a particular alignment of the plurality of pivot and rotation alignments;
- a plurality of legs coupled to the assembly configured to extend from the assembly and position the assembly and the guide member above a surface of a patient, such that a pivot point of the guide member is provided above the surface of the patient;
- and
- a trajectory tool configured to orient the guide member in a particular trajectory of a plurality of trajectories by concurrently controlling selection of:
- one of the plurality of pivot and rotation alignments between the guide member and the assembly, a pivot point alignment of a plurality of pivot point alignments between the assembly and a first end of at least one of the plurality of legs, one of a plurality of pivot and rotation alignments between each of a plurality of feet affixed to the surface of the patient and a corresponding second end of each of the plurality of legs, and an adjustment amount of an adjustable length of at least one of the plurality of legs.
A trajectory guide comprising:
- guide means for guiding an instrument or an apparatus along a particular trajectory towards a target beneath a surface of a patient;
- assembly means for holding the guide means and allowing the guide means to rotate and pivot in a plurality of pivot and rotation alignments, with respect to the assembly means;
- locking means for locking the guide means in a particular alignment of the plurality of pivot and rotation alignments, the particular alignment being associated with the particular trajectory;
- support means for supporting the assembly means and the guide means above the target and the surface of the patient, such that a pivot point of the guide means is provided above the surface of the patient;
- and
- trajectory tool means for orienting the guide means in the particular trajectory of a plurality of trajectories by concurrently controlling selection of:
- one of the plurality of pivot and rotation alignments between the guide means and the assembly means, a pivot point alignment of a plurality of pivot point alignments between the assembly means and a first end of the support means, one of a plurality of pivot and rotation alignments between affixing means for affixing to the surface of the patient and a corresponding second end of the support means and, and an adjustment amount of an adjustable length of the support means.
A method for setting a trajectory of a trajectory guide, the trajectory guide comprising:
- a guide member;
- an assembly configured to hold the guide member such that the guide member pivots and rotates with respect to the assembly to obtain a plurality of pivot and rotation alignments between the guide member and the assembly;
- a lock coupled to the assembly configured to lock the guide member in a particular alignment of the plurality of pivot and rotation alignments;
- a plurality of legs coupled to the assembly configured to extend from the assembly and position the assembly and the guide member above a surface of a patient, such that a pivot point of the guide member is provided above the surface of the patient;
- and
- a trajectory tool configured to orient the guide member in a particular trajectory of a plurality of trajectories,
- the method comprising:
- obtaining the particular trajectory by concurrently controlling, by the trajectory tool, selection of:
- one of the plurality of pivot and rotation alignments between the guide member and the assembly, a pivot point alignment of a plurality of pivot point alignments between the assembly and a first end of at least one of the plurality of legs, one of a plurality of pivot and rotation alignments between each of a plurality of feet affixed to the surface of the patient and a corresponding second end of each of the plurality of legs, and an adjustment amount of an adjustable length of at least one of the plurality of legs.
