Endoscope attachment mechanisms and methods of use
Some implementations of the disclosure relate to an adapter, comprising: a distal part comprising: a first channel running through the length of the distal part from a first opening at a distal end of the adapter to a second opening at a proximal end of the distal part, wherein a shaft of an endoscope is configured to be threaded through the first channel; and a second channel configured to removably couple the adapter to an outer surface of an instrument such that, after the shaft of the endoscope is threaded through the first channel, a tool portion of the instrument is adjacent the shaft of the endoscope; and a first coupler proximal to the distal part, the first coupler configured to be locked to a second coupler of the endoscope after the shaft is threaded through the first coupler and the first channel.
1 . An adapter, comprising:
a distal part comprising:
a first channel running through a length of the distal part from a first opening at a distal end of the adapter to a second opening at a proximal end of the distal part, wherein a shaft of an endoscope is configured to be threaded through the first channel; and
a second channel that is circumferentially open, an interior surface of the second channel comprising one or more protrusions configured to removably and lockingly engage the adapter to an outer surface of an instrument such that, after the shaft of the endoscope is threaded through the first channel, a tool portion of the instrument is adjacent the shaft of the endoscope, the one or more protrusions comprising:
a first protrusion configured to engage a first groove of the outer surface of the instrument; and
a second protrusion configured to engage a recessed indentation of the outer surface of the instrument, the recessed indentation positioned adjacent the first groove; and
a first coupler proximal to the distal part, the first coupler configured to be locked to a second coupler of the endoscope, proximal to the shaft, after the shaft is threaded through the first coupler and the first channel.
2 . The adapter of claim 1 , further comprising: a rotatable joint configured to enable longitudinal rotation of the distal part relative to the first coupler.
3 . The adapter of claim 1 , wherein:
the first channel is circumferentially closed.
4 . The adapter of claim 1 , wherein the second protrusion is a spring-loaded protrusion.
5 . The adapter of claim 1 , wherein the one or more protrusions further comprise: a third protrusion configured to engage a second groove of the outer surface, the third protrusion being positioned longitudinally adjacent to the first protrusion.
6 . The adapter of claim 1 , wherein the adapter is configured to be secured to the outer surface of the instrument by placing the outer surface of the instrument into the second channel and sliding the outer surface relative to the second channel such that first groove is secured by the first protrusion and the second protrusion is secured in the recessed indentation.
7 . The adapter of claim 1 , wherein the outer surface is on a handle portion of the instrument.
8 . An endoscope attachment assembly, comprising:
an endoscope;
an instrument comprising a tool portion and a handle portion; and
an adapter comprising:
a distal part comprising:
a first channel running through a length of the distal part from a first opening at a distal end of the adapter to a second opening at a proximal end of the distal part, wherein a shaft of the endoscope is configured to be threaded through the first channel; and
a second channel that is circumferentially open, an interior surface of the second channel comprising one or more protrusions configured to removably and lockingly engage the adapter to an outer surface of the handle portion of the instrument such that, after the shaft is threaded through the first channel, the tool portion of the instrument is adjacent the shaft of the endoscope; and
a first coupler proximal to the distal part, the first coupler configured to be locked to a second coupler of the endoscope, proximal to the shaft, after the shaft is threaded through the first coupler and the first channel.
9 . The endoscope attachment assembly of claim 8 , wherein:
the one or more protrusions comprise a first protrusion and a second protrusion; and
the outer surface of the handle portion comprises a first groove configured to engage the first protrusion, and a recessed indentation configured to engage the second protrusion.
10 . The endoscope attachment assembly of claim 9 , wherein the second protrusion is a spring-loaded protrusion.
11 . The endoscope attachment assembly of claim 9 , wherein:
the one or more protrusions further comprise a third protrusion; and
the outer surface of the handle portion further comprises a second groove configured to engage the third protrusion, the second groove being positioned longitudinally adjacent to the first groove.
12 . The endoscope attachment assembly of claim 9 , wherein the adapter is configured to be secured to the outer surface by placing the outer surface into the second channel and sliding the outer surface relative to the second channel such that first groove is secured by the first protrusion and the second protrusion is secured in the recessed indentation.
13 . The endoscope attachment assembly of claim 8 , wherein the instrument is a forceps instrument or a suction instrument.
14 . The endoscope attachment assembly of claim 8 , wherein the outer surface is on a top of the handle portion.
15 . The endoscope attachment assembly of claim 14 , wherein:
the first channel is circumferentially closed.
16 . The endoscope attachment assembly of claim 14 , wherein: when the endoscope and the instrument are coupled to the adapter, the instrument is configured to be below the endoscope.
17 . An endoscope attachment assembly, comprising:
an endoscope comprising a shaft and a first coupler proximal to the shaft;
an adapter comprising:
a distal part comprising:
a first channel running through a length of the distal part from a first opening at a distal end of the adapter to a second opening at a proximal end of the distal part, wherein the shaft of the endoscope is configured to be threaded through the first channel; and
a second channel that is circumferentially open, an interior surface of the second channel comprising one or more protrusions configured to removably and lockingly engage the adapter to an outer surface of an instrument such that, after the shaft is threaded through the first channel, a tool portion of the instrument is adjacent the shaft of the endoscope; and
a second coupler proximal to the distal part, the second coupler configured to be locked to the first coupler of the endoscope, proximal to the shaft, after the shaft is threaded through the second coupler and the first channel.
