Abstract
A surgical instrument navigation system and method of use is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient, wherein the surgical instrument, as provided, may be a steerable surgical catheter with a biopsy device and/or a surgical catheter with a side-exiting medical instrument, among others. Additionally, systems, methods and devices are provided for forming a respiratory-gated point cloud of a patient's respiratory system and for placing a localization element in an organ of a patient.
Claims18
A surgical catheter, comprising:
- an elongate flexible shaft having a proximal end portion, an opposite distal end portion, a longitudinal axis, and an outer wall extending from the proximal end portion to the distal end portion;
- a handle attached to the proximal end portion;
- the distal end portion defining an auger housing, the auger housing defining a tissue collection region and an exit opening;
- an auger device housed within the auger housing comprises an auger bit and an actuation wire operatively connected thereto, the actuation wire extends proximally from within the auger housing to the handle, the auger device is actuatable between a first position within the auger housing through the exit opening to a second extended position outside the auger housing.
