Abstract

Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a plasma bipolar cutter head. Background Art
[0002] The low-temperature plasma surgical system uses a 100KHz radio frequency electric field to excite the electrolyte (physiological saline) to form a thin plasma layer with a thickness of about 50 microns around the electrode. The plasma layer is composed of a large number of charged particles, which generate enough energy (electron volts) to open the molecular bonds that constitute the target tissue cells at low temperatures (40℃-70℃), so that the tissue can be quickly decomposed into low molecular weight molecules and atoms, thereby achieving both efficient tissue cutting and ablation and coagulation and hemostasis effects at lower temperatures. Since the tissue is not directly destroyed, the damage to the surrounding tissue is minimal, and the current does not flow directly through the tissue, the tissue heat is minimal, and the treatment temperature is low. Therefore, with the characteristics of "minimally invasive, precise, convenient, and safe", the low-temperature plasma system has been widely used in the treatment of diseases such as otolaryngology, urology, and spinal surgery in recent years, and has been tried in neurosurgery and has been proven to have good results.

A drip outlet 9 connected to the front end of the pre-buried water channel 8 is opened at the front end of the first tweezers 1 and / or the second tweezers 2, and a drip joint 10 is connected to the rear end of the pre-buried water channel 8.
[0026] Physiological saline drips onto the surgical site through the drip joint 10, the pre-buried water channel 8 and the drip port 9 in sequence, which plays a role in assisting cooling and reducing tissue adhesion during coagulation and hemostasis.
[0027] Specifically, the drip port 9 is opened on the inner side of the first tweezers blade 1 and / or the second tweezers blade 2 , and the drip port 9 is located at the rear side of the tweezers tip 3 and / or the annular working head 4 .
