Surgical diathermy is usually better known as "electrosurgery". (It is also referred to occasionally as "electrocautery", but see disambiguation below.) Electrosurgery and surgical diathermy involve the use of high-frequency A.C. electric current in surgery as either a cutting modality, or else to cauterize small blood vessels to stop bleeding ...

These were limited to frequencies of 0.1 – 2 MHz, called "longwave" diathermy. The current was applied directly to the body with contact electrodes, which could cause skin burns. In the 1920s the development of vacuum tube machines allowed frequencies to be increased to 10 – 300 MHz, called "shortwave" diathermy. The energy was applied to ...
[2] [3] Today, machines with the name Hyfrecator are sold only by ConMed Corporation. However, the word "hyfrecator" is sometimes used as a genericized trademark to refer to any dedicated non-ground-return electrosurgical apparatus, and a number of manufacturers now produce such machines, although not by this name.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.

There are many different surgical specialties, some of which require specific kinds of surgical instruments to perform. General surgery is a specialty focused on the abdomen; the thyroid gland; diseases involving skin, breasts, and various soft tissues; trauma; peripheral vascular disease; hernias; and endoscopic procedures.
The first surgical procedures to reduce intraocular pressure of the eye, by decreasing production of aqueous humor, by damaging the ciliary body by diathermy, penetrating cyclodiathermy or surgical excision was done in the early twentieth century. [1] Cyclodestruction by diathermy was first performed by Weve in 1933. [11]
