  • the grooves can be circular (e.g., groove 286), zig-zag (e.g., groove 288), triangular shaped with rounded edges (e.g., groove 290), diamond shaped (e.g., groove 292), and/or oval shaped (e.g., 294). While different groove shapes are shown, other grooves shapes could be used.
  • channels can include a suction/biopsy channel, air insufflation channel, water delivery channel, electronics/visualization channel, and other channels.
  • channels can snap fit into grooves 286-294.
  • channels can slid into grooves 286-294 from a distal end of insertion portion 284.
  • the channels can couple at a proximal portion of the endoscope to reduce movement of the channels during use of endoscope 280.
  • the channels can be shaped such that when received by grooves 286-294, a smooth outer surface of insertion portion 284 is created.
  • the channels can facilitate ease of removal of channels for replacement and/or cleaning.
  • the channels can be disposable.
  • the channels may be designed for single use and will be replaced prior to each use of the endoscope.
  • the channels may be fabricated from or coated with materials that include antimicrobials materials such as silver, zinc, or titanium in ionic or nanoparticle forms. In some cases, the channels will have no acute angulations throughout their course, facilitating adequate cleaning and disinfection.
  • insertion portion 284 can include both removable channels and non-removable channels.
  • grooves 286-294 define channels that can receive a liner.
  • Single-use channel lines can prevent abrasion of underlying channel surfaces.
  • Channel liners can be easily inserted and removed from the channels.
  • channel liners can be composed of plastic or other materials. Both suction/biopsy and air/water channels can be equipped with liners.
  • the liner can be pre-cut to length. In some cases, the liner can couple to a distal portion of insertion portion 284 and/or a proximal portion of endoscope 280 to secure the liner in place.
  • endoscope 280 can include a transition region 282.
  • Transition region 282 can define a location where channels insert inside endoscope body 204 while remaining external on insertion portion 284.
  • insertion portion 284 can include a central passage 296.
  • Central passage 296 can be autoclavable (to facilitate sterilization, for example).
  • central passage 296 can provide access for imaging or other electronics described herein.
  • electronics of insertion portion 284 can be passed through central passage 296 can couple to a distal portion of body 204 for electrical connection.
  • endoscope 280 can include an extension of electronics that can be passed through central passage 296 of a removable insertion portion 284.
  • electronics of endoscope 280 can be a detachable end piece, similar to that described in Figures 13 and 14.
  • insertion portion 284 can include one or more tip deflector mechanisms 298.
  • Tip deflector mechanisms 298 can be in communication with endoscope head 202 to allow movement of a distal portion of insertion portion 284.
  • a tip deflection mechanism can be housed in the central passage 296 or in a channel or channels within grooves 286-294.
