Closed cutting pliers head device of high-frequency bipolar closed cutting pliers

Abstract

The invention relates to a closed cutting pliers head device of high-frequency bipolar closed cutting pliers. The device is characterized by comprising a first closed pliers head (1), a closed pliers head pin (2), a second closed pliers head (3), an insulating pliers head baffle piece (4), a pliers head push-and-pull bar (5), a cutter blade push-and-pull pipe (6), an external aluminum pipe (7) and a cutting blade (26). In the closed cutting pliers head device of the high-frequency bipolar closed cutting pliers, the operation of closing and cutting is separated, a high-frequency bipolar pliers head adopts a single-handle holding mode for open and close, saves labor, is comfortable, is provided with a locking device, is reliable in motion and is convenient to use. By adopting an independent cutting device, accurate cutting at the closing position of the pliers head is realized through hooking a trigger by a forefinger, and the depth of cutting is controllable. By arranging an insulating component at the position of the pliers head of the closed cutting pliers head device of the high-frequency bipolar closed cutting pliers, the closing of the pliers head and the cutting of the blade cannot be affected, effective insulation can be realized, the application of a high-frequency electrode is ensured, and the device is convenient to clean.

Description

Technical field [0001] The invention relates to a high-frequency electrosurgical instrument, in particular to a high-frequency bipolar closed cutting forceps closed cutting forceps head device. The invention can be used in various clinical departments to close and cut vessels and lymphatic vessels during surgery and to fit the size of electrode jaws The tissue bundle. The instrument is specially designed for closed cutting of tissues and vessels in endoscopic and open surgery. Background technique [0002] At present, the unipolar high-frequency electrosurgical unit uses a circuit to cut and coagulate the tissue. This circuit consists of the high-frequency oscillator and amplifier in the electrosurgical unit, the patient, connecting wires and electrodes. In most applications, active wires and electrodes are used to output current to the surgical site. This monopolar cutting method uses the patient as an electrode in the passage, which easily applies excessive high-frequency ener...
