ELECTROSURGICAL INSTRUMENT AND METHOD OF ITS MANUFACTURING Russian patent published in 2023 - IPC A61B18/14 

FIELD: medical devices.

SUBSTANCE: group of inventions relates to an electrosurgical instrument and a method of its manufacturing. The electrosurgical instrument has a first jaw, a second jaw and an electrical connecting device for external electrical connection. The electrical connecting device is electrically connected to the first tissue-contacting surface of the first jaw through a first conductor, and electrically connected to a second tissue-contacting surface of the second jaw through a second conductor. A method of manufacturing an electrosurgical instrument includes separating the first conductor from a plate and the second conductor from a plate, electrically connecting the first conductor to the first tissue contacting surface, arranging the first tissue contacting surface, the first conductor and the second conductor in a first mold, and manufacturing the first jaw by filling the first mold with a flowable, curable material in such a way that at least one contact part of the contact area of the second conductor is located in the support recess of the first jaw, the arrangement of the electrically conductive support journal and the second tissue contacting surface electrically connected to the core in the second mold, and the manufacture of the second jaw by filling the second mold with a flowable, curable material, inserting the support pin of the second jaw into the support recess of the first jaw to hinge both jaws to each other.

EFFECT: use of a group of inventions makes it possible to ensure tissue sealing.
