Tips About the Jumbo Forceps
A) This forceps has larger capacity than traditional biopsy forceps, and the cusps open to almost 10 mm.
B) These forceps cannot be used with diagnostic gastroscopes, as they require a working channel of at least 3.2 mm (most diagnostic gastroscopes have 2.8 mm channel).
C) If you are going to biopsy Barrett’s esophagus with the jumbo forceps and don’t have therapeutic gastroscope, you can use a colonoscope.
D) This specific jumbo forceps has a spike, which facilitates obtaining two biopsies.
E) The cusps are also “fenestrated”. This fenestration or opening on the sides of the cusps allow for tissue to be “squeezed” out of the cusp. When the second bite of tissue is obtained, it squeezes the previous bite. Thus, in theory, you can obtain two good bites of tissue.
