Abstract

System and method for advancing and retracting a tubular medical instrument within a body lumen and evacuating lumen material therefrom. A shaft of the medical instrument is inserted through a central bore of a probe, an evacuation adaptor, and a swivel fastener unit, respectively mounted onto a distal carriage, a central carriage, and a proximal carriage of a translation mechanism. The probe is directed toward cavity entrance of body lumen using an adjustment mechanism coupled to a translation mechanism beam. A central probe unit of probe is maintained sealingly coupled to cavity entrance by propelling distal carriage along beam. The evacuation adapter is maintained sealingly coupled to the probe by propelling central carriage along beam, concurrent with displacement of a hollow tube of probe relative to central probe unit. Lumen material is evacuated using evacuation adaptor. The medical instrument is advanced and retracted by propelling proximal carriage along beam.

Dependent claims

A system for advancing and retracting a tubular medical instrument within a body lumen and evacuating lumen material therefrom, the system comprising:

a probe, comprising a hollow tube and a central probe unit through which the hollow tube is moveably inserted, the probe configured to hold a shaft of the tubular medical instrument;
an evacuation adaptor, disposed proximal to the probe, and configured to hold the shaft of the tubular medical instrument, and to enable the evacuation of lumen material;
a swivel fastener unit, disposed proximal to the probe, and configured to hold the shaft of the tubular medical instrument;
a translation mechanism, comprising:
a beam;
and a plurality of translation mechanism carriages comprising:
a distal carriage, configured to mount the probe, the distal carriage comprising a distal drive configured to propel the displacement of the distal carriage along the beam;
a central carriage, configured to mount the evacuation adaptor, the central carriage comprising a central drive configured to propel the displacement of the central carriage along the beam;
and
a proximal carriage, configured to mount the swivel fastener unit, the proximal carriage comprising a proximal drive configured to propel the displacement of the proximal carriage along the beam;
and
an adjustment mechanism, coupled to the beam and configured to enable adjustment of the beam along at least one translational or angular direction,
wherein the probe is directed toward a cavity entrance of the body lumen using the adjustment mechanism, the central probeunit is maintained sealingly coupled to the cavity entrance by propelling the distal carriage along the beam, the evacuation adapter is maintained sealingly coupled to the probe by propelling the central carriage along the beam, concurrent with the displacement of the hollow tube relative to the central probe unit, wherein lumen material is evacuated from the body lumen using the evacuation adaptor, and wherein the tubular medical instrument is advanced and retracted within the body lumen by propelling the proximal carriage along the beam.
