be seen by visual inspection.
4.1.3.2 pH. Compared with the blank control solution of the same batch, the pH
difference shall be less than 2.0.
4.1.4 Hardness
The forceps head shall meet the hardness requirements specified by the manufacturer.
4.1.5 Surface and internal material consistency
The manufacturer shall claim that the surface of the part of the device made of metal
material is consistent with the internal material. If it is really necessary to coat the
surface of the device, the manufacturer shall give the corresponding coating
requirements and test methods.
4.2 Appearance
4.2.1 Under the endoscopic field of view, the visible tip portion of the surgical
instrument shall be treated, so as to eliminate possible directional reflections.

The forceps heads shall open and close smoothly. When the forceps rods are opened
and closed, there shall be no shaking that interferes with the user's use.
4.4.2 Clamping force
There shall be a certain clamping force.
4.4.5 Rotation performance (for needle forceps with rotation function)
Rotation shall be smooth. When the forceps rods are rotated, there must be no shaking
that interferes with the user's use.
