Thermocautery
A thermocautery ( ancient Greek θερμὁς thermós “warm” and καίω kaio “ burn ”) is a surgical instrument used in medicine for the targeted destruction of tissue .
The targeted destruction of tissue, known as cauterization , is used to stop the bleeding quickly . It therefore finds u. a. Use in operations on the male member , such as circumcision . Historically, the metallic surgical instrument was first heated in a fire . A historically common design is the gas-powered Paquelin burner, which makes a hollow platinum tip filled with finely divided platinum glow . Electrically heated cautery is also known as galvano cautery or more modernly as electrocautery .
Electrocautery is used in ophthalmic surgery, for example in strabismus operations . Here they ensure fast wound closure in areas with a high blood flow, such as the muscle insertions of the vertical obliqui , to which the vortex veins are directly adjacent. They are also used in certain cases to cut through muscle tissue and tendons . Even with the so-called limbal incision , the vessels can be gently closed with careful cauterization.
Another ophthalmological area of application for the electrocautery is the removal of small eyelid and conjunctival tumors, as well as the closure of the teardrop in pathologically “ dry eyes ”.
