Problems solved by technology

Therefore, precise position tracking of a flexible miniature secondary endoscope using a fiber optic shape sensor is much more difficult than tracking a larger but less flexible conventional primary endoscope.
For example, as shown in Figure 1, accurate position tracking of a flexible miniature secondary endoscope using a fiber optic shape sensor is much more difficult than tracking a larger but less flexible primary endoscope 20

Embodiment Construction

[0019] like figure 2 As shown in , one embodiment of the telescoping endoscope of the present invention employs a primary endoscope 30 and a miniature secondary endoscope 40 deployed within the instrument channel of the primary endoscope 30 . The telescopic endoscope also employs a secondary endoscope tracker, which includes two (2) sensors 32 and a plurality of markers aligned axially along the miniature secondary endoscope 40, as determined by the 40 as indicated by the hatching.

[0020] As this article will combine Figure 10-12 As further explained in the description, the premise of the present invention is to track a portion of the miniature secondary endoscope 40 extending from the end D of the instrument channel of the primary endoscope 30 , as opposed to tracking the entire miniature secondary endoscope 40 . Thus, as the miniature secondary endoscope 40 is translated within the primary endoscope 30 in either the proximal P direction or the distal direction D, the se...

Abstract

A retractable endoscope employing a primary endoscope (30, 50) having an instrument channel, a miniature secondary endoscope (40, 50) deployed within the instrument channel of the primary endoscope (30, 50) 60), and an endoscope tracker comprising one or more sensors (32, 61) and one or more markers (41, 52) for interactively sensing Any portion of the miniature secondary endoscope (40, 60) that extends from the end of the instrument channel.

Description

technical field [0001] The present invention generally relates to relative tracking of telescoping endoscopes having a miniature secondary endoscope deployed within the instrument channel of a larger primary endoscope. The present invention specifically relates to integrating the tracking of both primary and secondary endoscopes to minimize position errors that may occur in the individual optical tracking of miniature secondary endoscopes. Background technique [0002] To perform a biopsy it is often necessary to access the distal regions of the lung. Endoscopy To access regions further than the fifth (5th) to sixth (6th) branch points of the bronchial tree, a miniature secondary endoscope can be used, in which instruments are usually passed through a larger primary endoscope The channel deploys the miniature secondary endoscope. For example, FIG. 1 illustrates a miniature secondary endoscope 21 deployed within a primary endoscope 20 whereby the miniature secondary endosco...
