Powered Stereotactic Positioning Guide Apparatus

摘要

The present invention presents an apparatus and methods to stereotactically guide insertion of invasive tubular devices to a tissue object of a living body. The apparatus comprises a powered positioning guide control assembly and a positioning guide assembly that is operably detachable from the powered positioning guide control assembly, and rotationally adjustable and lockable. The powered positioning guide control assembly encloses an ultrasound transducer to visualize and target the tissue object, and adjusts an insertion angle of an invasive tubular device placed in the positioning guide assembly.

主权项

1. A powered stereotactic positioning guide apparatus, comprising:
a positioning guide means, controlled by and operably detachable from a positioning guide control means; the positioning guide means, provided in one or a plurality of mechanical configurations, which an invasive tubular device slidably passes through, which directs the invasive tubular device in a range of insertion angles to a tissue object, which has means to rotationally adjust and reversibly lock the insertion angle of the invasive tubular device, which reversibly couples with and uncouples from the positioning guide control means, and which reversibly adheres to a skin overlying the tissue object; and the positioning guide control means, provided as one or a plurality of operating devices having one or a plurality of mechanical and electronic configurations, which has a powered means to align a longitudinal axis of the invasive tubular device in the positioning guide means with the tissue object in an ultrasonographic field, which measurably and controllably adjusts the insertion angle of the invasive tubular device, and which encloses an ultrasound transducer.
