What is the difference between bipolar electrocoagulation and monopolar electrocoagulation?
In addition, bipolar electrocoagulation can similarly act as an electrical coagulation agent in the presence of fluids such as saline, cerebrospinal fluid, or blood, which is less than monopolar electrocoagulation. Use a variety of monopolar electrocoagulation with various surgical instruments such as forceps, tweezers, aspirator, knife or wire trap and contact to stop bleeding or cutting; but the required power, thermal diffusion range, to the surrounding tissue damage, at a distance of 1 cm resection may still be seen the organization change the monopolar electrocoagulation in important parts such as the cortex, brainstem, and blood vessels near the spinal cord, nerve root etc. should not be used.
One stage electrocoagulation is to contact one of the larger metal plates with the patient's buttocks as one of the clicks, referred to as "patient clicks" or "ineffective electrodes", while the other electrode is connected with the hemostatic apparatus for electrical coagulation.Bipolar electrocoagulation: the two electrical coagulation is respectively connected to the two blades of a pair of tweezers, and the two blades of the tweezers are insulated.
The advent of bipolar coagulation in early 1940, and the difference is that the monopolar electrode is in contact with the patient to cancel the invalid hips, and two electrodes are respectively connected with a pair of tweezers two blades, two blades between the tweezers is insulated. When the current application only after two tip tweezers between organizations, so the power required is greatly reduced, generally only the monopolar 1/4 to 1/3, in the important parts such as spinal cord bleeding can be reduced to less than even the power of monopolar electrocoagulation 1/10 diffusion, so hot and the adjacent damage were decreased.
