Medical Endoscopes – Rigid Resectoscope
1 Scope
This Standard specifies the classification and composition, requirements and test
methods of rigid resectoscope.
This Standard is applicable to the rigid resectoscope (hereinafter referred to as
resectoscope). The resectoscope is clinically applicable to the cutting, vaporizing and
coagulating operations against the diseased tissues under the direct viewing of
endoscope and using the high-frequency current thermal effect.

The manufacturer shall indicate in the instruction manual the possibility of heat and
other risks to the patient and operator when using the product.
a) Thermal damage to the endoscope due to electrical spark or capacitively coupling
high-frequency current;
b) Image interference on the video screen caused by high-frequency
electromagnetic waves;
c) Keep the working part of the charged electrode within the operator’s observation
range to avoid accidental high-frequency burns;
d) In order to ensure that the charged electrode in the correct position during the
operation, it must be kept sufficient distance away from the head end of the
endoscope; it shall avoid contacting with the metal parts and other conductors of
the endoscope before exciting the high-frequency output, including the liquid
vent that may be conductor;
