摘要:
A patient defines a patient space in which an instrument can be tracked and navigated. An image space is defined by image data that can be registered to the patient space. A tracking device can be connected to a member in a known manner that includes imageable portions that generate image points in the image data. The tracking device can be tracked to register patient space to image space.
摘要:
An instrument tracking device for cooperating with an instrument during a surgical procedure where the instrument has an elongated body extending along a first longitudinal axis and including a working member at a distal tip includes a body having a distal end and a proximal end. An opening can be formed through the body along a second longitudinal axis. The opening can define a passthrough in the body from the distal end to the proximal end. A first tracking coil can be disposed in the body and can define a first tracking coil axis that is substantially coaxial with the second longitudinal axis of the body. A connection mechanism cooperates between the elongated housing and the body that secures the body to the elongated housing of the instrument upon passing at least a portion of the elongated housing through the passthrough of the body in an assembled position.
摘要:
Image data can be obtained with an imaging device. A location of the imaging device relative to a subject can be determined. A location of an instrument can be tracked relative to the subject using two or more tracking systems operating with different tracking modalities. Also, the tracked location of the instrument can be illustrated relative to the image data.
摘要:
A navigation system generally determines a location of a portion of a first medical instrument relative to a patient. The navigation system generally includes a multi-configuration tracking array that extends from the first medical instrument. A plurality of tracking devices can be positioned on the multi-configuration tracking array. At least one of the tracking devices changes to define at least a first condition and a second condition. A tracking system detects the tracking devices and relates a change between the first condition and the second condition with a change between at least a first instrument configuration and a second instrument configuration.
