Abstract
Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.
Claims20
A method of performing a guided interventional medical procedure using a template, the method comprising:
- obtaining at least one medical image of a patient's anatomy, the at least one medical image including at least one anatomical target;
- generating, via a computer device, a virtual template that is positioned and oriented at a planned location relative to the at least one anatomical target on the at least one medical image, wherein the virtual template comprises at least one channel passing there-through along a trajectory determined to intersect with the at least one anatomical target;
- and
- causing a physical template to be manufactured that replicates the virtual template, the physical template comprising:
- (i) a template body, and
- (ii) at least one template channel that replicates the at least one channel of the virtual template, and that enables passage of a medical device through the template body;
- wherein the template body comprises:
- a first plate and a second plate separated by at least one spacer,
- the first plate comprising a first side of the template body that includes an entrance of the at least one template channel, and
- the second plate comprising a second side of the template body that includes an exit of the at least one template channel.
