Medical bipolar surgical electrode and manufacturing method thereof

Abstract

The invention provides a medical bipolar surgical electrode and a manufacturing method thereof. An electrode knife head is provided with contact isolation insulation columns; a knife tip of the electrode is provided with an excitation contact made of metal guide wires; the surface of an electrode knife bar is insulated; a metal tube is arranged in the electrode knife bar; the bare part of the metal tube, which is exposed at the working end of the knife head and is insulated in surface, serves as a backflow contact; and the electrode is provided with a priming system which consists of a water injection catheter, an electrode inner water filling pipe and an electrode tip water filling nozzle, or is provided with a drainage system which consists of an electrode tip suction opening, an electrode inner drainage tube and a drainage catheter, or is provided with both the priming system and the drainage system. Physiological saline can be guided to a to-be-treated part from a saline bag (bottle), or tissue fragments and the saline are guided to a waste liquid bottle of a vacuum extractor from the to-be-treated part. The surgical electrode has multiple functions of tissue dissecting, tissue drying, tissue ablation, blood coagulation and saline infusion or / and the functions of the vacuum extractor, and is especially suitable for open and microendoscopic complicated surgical procedures.

Description

Technical field [0001] The invention relates to a medical surgical electrode and a manufacturing method, in particular to a bipolar electrode capable of performing tissue dissection, tissue drying, tissue ablation, or low temperature coagulation during surgery. Background technique [0002] At present, in the known surgical electrodes, the excitation contact and the return contact of a type of electrode are separated from each other, the needle-shaped excitation contact contacts the lesion, and the sheet-shaped (electrode sheet) return contact is attached to the patient. It is called a monopolar electrode. Another type of electrode is to provide both excitation contact and current return contact at the workpiece end, which is called bipolar electrode in medical profession. When the bipolar electrode works, the electric field does not pass through the human body, so it has more advantages in safety. [0003] In the field of bipolar electrodes, bipolar tweezers, which are us...
