What are the advantages of using a rigid endoscope compared to flexible scopes?
What are the advantages of using rigid endoscopes over flexible scopes?
Cheaper and less prone to damage than flexible scopes; Superior image compared with most flexible scope systems; Allows larger instruments to be used alongside the scope; Variety of sizes: typical example Outer diameter 2.7mm; length 18cm; viewing angle 30°; Additional equipment required: Sheaths protect the scope allow fluids to pass through side ports
What are the limitations of rigid endoscopes?
Risk of causing damage and mucosal bleeding which restricts ability to see lesions eg rhinoscopy/urethroscopy; Unable to manoeuvre around anatomical bends; No real ability to insufflate with air effectively.
What are some of the uses of small animal rigid endoscopes?
Rhinoscopy; Arthroscopy; Cystoscopy in bitches; Laparoscopy
