Abstract
Systems and methods are configured to adjust a surgical trajectory pursuant to a surgical intervention. The systems and methods are configured to grossly align an aiming device to the target surgical trajectory wherein the aiming device is coupled to a patient. An intraoperative computerized tomography (iCT) scan is used to obtain an image of a surgical field. An actual trajectory of a CT-visible element is obtained and extended forward down to a surgical plan's target depth for comparison to the target surgical trajectory. The actual trajectory is adjusted to obtain an adjusted trajectory prior to insertion of a device via the aiming device into the patient.
Claims25
A method of adjusting a surgical trajectory pursuant to a surgical intervention, comprising:
- obtaining a target surgical trajectory into a patient;
- grossly aligning an aiming device to the target surgical trajectory wherein the aiming device is coupled to the patient;
- coupling a CT-visible element to the aiming device;
- using intraoperative computerized tomography (iCT) scan to obtain an image of a surgical field;
- obtaining an actual trajectory of the CT-visible element and extending forward the actual trajectory down to a surgical plan's target depth for comparison to the target surgical trajectory;
- causing a line representative of the actual trajectory to be shown on the image wherein the line corresponds to a long axis of the CT-visible element;
- adjusting the actual trajectory to obtain an adjusted trajectory prior to insertion of a device via the aiming device into the patient.
