A kind of manufacturing method of loop negative plate

Abstract

The present invention relates to the field of medical device manufacturing, in particular to a method for manufacturing a negative electrode plate of a circuit, which includes pasting a self-adhesive under the metal foil and performing die-cutting to obtain the desired shape; Paste the foam sheet; Place a conductive adhesive mold on the top of the foam sheet to form a glue injection area around the metal foil, and drip a certain amount of conductive adhesive raw material solution into the conductive adhesive mold; The viscose raw material solution is cured; the release film is pasted and then die-cut to remove the excess foam sheet and release film to obtain the finished loop negative plate. In the manufacturing method of the loop negative plate provided by the present invention, the conductive adhesive mold is matched with the foam sheet to form a glue injection area on the periphery of the metal foil. The conductive adhesive layer of the main body can solve the problem of the edge exposure of the metal foil of the negative plate of the loop, and also simplifies the production process and reduces the production cost.

Description

technical field [0001] The invention relates to the field of medical device manufacturing, in particular to a method for manufacturing a loop negative plate. Background technique [0002] The high-frequency electric knife uses the principle of RF (Rad io Frequency) to apply high-frequency and high-voltage current to the patient's part through the knife pen, and uses the tip of the knife pen to produce instantaneous ablation on the contacted tissue to achieve cutting and healing. The purpose of hemostasis. The high-frequency electric knife needs to be used in conjunction with the negative plate of the circuit, and the high-frequency and high-voltage current that acts on the knife pen to the human body is recycled to the electric knife in the fastest, lowest impedance and safest form to form a complete circuit. The loop negative plate is also called the neutral electrode. The existing commonly used disposable loop negative plate is mainly composed of foam carrier, metal foil...
