Functionality

In bipolar HF surgery, tissue coagulation is achieved by
applying a high-frequency AC current, which generates heat.
The NightKNIFE and LIGATOR ligation instruments are
invasive surgical instruments for use in laproscopic or open
surgery. They are used through surgically generated access
openings in conjunction with products for endoscopic use,
such as trocars and optics.
The active electrodes (branches) are the non-insulated areas
of the jaws.
The HF current flows from one branch of the instrument
through the biological tissue to the other branch to produce
the desired localized coagulation effect.
With this method, sealing of a vessel or tissue segment
carrying blood is achieved by HF current in combination with
supplementary pressure.
The sealed location is hemostatically tight with respect to
systolic blood pressure and permanently closed.
The integrated cutting function of the NightKNIFE allows the
tissue under treatment to be separated immediately after
sealing without first changing instruments.
The jaws of the jaw insert can be opened or closed by
actuating the handle, and they can be locked in place with
the ratchet lever.
The jaw insert can be turned and locked using the fluted
knob on the shank tube (8x 45°).
