Objective: Properly identify specialized instruments and all of their parts, and understand the set up, care, and
maintenance of each.
Endoscopy
The technique of examining internal anatomy using optical instrumentation View internal body structures via an orifice ; not an incision Examine tissues directly; remove foreign bodies; biopsy organs General anesthesia needed; intubation required for oral procedures
Types of Endoscopes
Flexible
Endoscope Capabilities
4 way distal tip deflection
Water flushing channel
Air insufflation channel
Suction power
Accessory channel
Common Endoscopic Procedures
Types of Endoscopes
Flexible Fiber optic Endoscope
Eyepiece for direct viewingCan attach a camera
Types of Endoscopes
Flexible Video Endoscope
Do not have a direct viewing lens and eye piece
All images are seen on a monitor
Can take photos or video
Types of Endoscopes
Rigid Endoscope
For procedures involving a direct pathway that are better viewed with a straight or direct line of sight Otoscopy, rhinoscopy, cystoscopy, arthroscopy, laparoscopy
Endoscopy Preparation
Veterinary technician is responsible for prep:Hook up endoscopeEnter patient data on computerTurn on machine and check light sourceSet up distilled water for flushingTest machine
Press the water valveSubmerge tip, cover the air valve, check for bubblesLeave tip submerged in water and press suction valve
Endoscopy Room
Endoscopy Room
Endoscopy Cabinet
Store endoscopes in a designated cabinet in a hanging position
Safe keeping; longer life;allows proper drying
Do not store in original padded case
Handling the Endoscope
Biopsy Sampling
Flexible biopsy forceps obtain the sample 1.8- to 2.4-mm cup for specimens
Use 25-27g needle to gently get sample out of the cups Sample storage?
Endoscopy Accessories
Biopsy forceps, wired snares, wire baskets, pronged grasping forceps, cytology brushes
Colonoscopy
Patient preparation: Perform fecal sampling before beginning procedureFast for 24 to 36 hours; NPO for 4 hoursRemove fecal material
Lavage solutions given orally Lavage colon (enema)
Endoscope Cleaning
Clean immediately with an enzymatic solutionMay use soapy distilled water
Endoscope Cleaning
All channels must be cleaned and sterilized!
