What is bipolar diathermy?

In bipolar diathermy, the two electrodes are found on the instrument itself. The bipolar arrangement negates the need for a dispersive electrode, instead a pair of similar sized electrodes are used in tandem. The current is then passed between the electrodes.

Can you cut with bipolar diathermy?

Bipolar electrosurgery uses lower voltages so less energy is required. But, because it has limited ability to cut and coagulate large bleeding areas, it is more ideally used for those procedures where tissues can be easily grabbed on both sides by the forceps electrode.

How does bipolar cautery work?

With the bipolar electrosurgical method a bipolar device, often a set of forceps, is used. The electrical current passes from one side of the forcep, through the target tissue to the other side of the forcep, then back to the generator.

How Does a diathermy machine work?

Diathermy uses high-frequency electric current to produce heat deep inside a targeted tissue. It can reach areas as deep as two inches beneath the skin’s surface. The diathermy machine does not apply heat directly to the body.

What is difference between unipolar and bipolar?

They are sometimes confused because both can include depressive episodes, but there are some key differences. The main difference between the two is that depression is unipolar, meaning that there are no periods of abnormally elevated mood, while bipolar disorder includes symptoms of mania.

What is the difference between monopolar and bipolar electrodes?

For example, bipolar electrosurgery typically involves lower voltage (requiring less energy) and is targeted toward smaller areas. Monopolar electrosurgery is versatile, with modalities including cut, blend, desiccation, and fulguration, and is effective for large areas.

Why is saline used in bipolar cautery?

Recent trials evaluating the safety and efficacy of bipolar resectoscopes have claimed advantages over standard monopolar resection (3-7). By using physiologic saline (0.9% NaCl) as irrigation fluid, it eliminates any danger of TUR syndrome and thus eliminates the conventional time limit of resection.

What are the risks of diathermy?

Results: The role of diathermy in surgical practice has expanded beyond imagination in recent years. The patient, surgeon and the theatre staff are frequently exposed to hazards such as burns injury, electrocution, hypoxic stress, inhalation of diathermy plume, and gene mutation.

What is a diathermy device?

Diathermy is the controlled production of “deep heating” beneath the skin in the subcutaneous tissues, deep muscles and joints for therapeutic purposes. There are basically two types of diathermy devices on the market today: radio or high frequency and microwave.

What is the difference between MDD and bipolar?

Bipolar depression, which is characterized by alternating (sometimes simultaneous) periods of depression and mania. Unipolar depression, more commonly known as major depression, which has no manic periods.
