Modes For Bipolar Cutting; Modes For Bipolar Coagulation - Daiwha Meditom DT-400S User Manual

3) Spray Coagulation
- 400KHz alternating current maximum modulated by 33KHz.
- For coagulation in specious area by spark caused by high Vp-p.
TIP How to apply Contact Coagulation mode
- Quality coagulation refers to even dehydration causing no carbonization as well as no
adhesion to electrode.
- It is very important to minimize the spark between electrode and tissue for the quality coagulation.
The following procedures are to ensure the quality coagulation.
- Let the output out with the electrode adhered to the tissue.
- Don't supply HF current (output) to the tissue for a long time.
- The output should be low enough to make coagulation. High output produces high voltage to the
tissue, resulting in spark increase.
- It is desirable to use a ball type of electrode because it generates less spark compared with other
types of electrodes. If possible, an electrode with small diameter is recommended if possible as you
need higher output in proportion to the diameter. Low output can make coagulation possible. Don't
use electrode of lancet or needle type as possible as it is subject to make spark at the edge.

4.4 Modes for Bipolar Cutting

- It is useful for elaborate coagulation and cutting in tiny area, blood vessel or nerve.
- If you hold tissue with Forceps, HF current circulated between the both handles makes the
tissues in the midst of handles coagulated by heating them.
- It reduces the risk of electrical shock as the current path is short.
1) BipolarCut
- Using non modulated 482KHz HF current.
- Use bi-polar scissors to treat blood.
- Especially useful for cutting blood vessels and minute tissue.
- It can be used for the coagulation of large tissue.

4.5 Modes for Bipolar Coagulation

1) BipolarStandard Coagulation
Standard Bi-polar Coagulation
- None modulated 482KHz alternating current.
- Especially high R.F power, it is good to large tissue coagulation.
