Description
Technical Field
The present disclosure generally relates to the field of medical ultrasonic surgery, and specifically relates to a high-frequency electrotome.
Background
By using the high frequency electrosurgical forceps, the surgeon can cauterize, coagulate/dehydrate, reduce or delay bleeding, and/or seal blood vessels by controlling the intensity, frequency, and duration of the high frequency electrosurgical energy applied to the tissue. Generally, the electrical configurations of high frequency electrosurgical forceps can be divided into two categories: 1) monopolar high-frequency electric knife forceps; and 2) bipolar electrosurgical forceps.
Monopolar surgical forceps utilize a surgical electrode associated with a clamping end effector and a remote patient circuit electrode or pad that is typically connected externally to the patient. When high frequency electrotome energy is applied, the energy is moved from the surgical electrode to the surgical site, through the patient and then to the return electrode.
Bipolar electrosurgical forceps utilize two conventional opposing electrodes located on the interior opposing surfaces of an end effector and electrically coupled to an electrosurgical generator. Each electrode is charged to a different voltage. Since tissue is a conductor of electrical energy, electrical energy may be selectively transmitted through the tissue as the tissue therebetween is grasped by the effector.
However, in the prior art, the problem of burning of the tissue occurs when the cutting is continued for a long time.
