High-frequency bipolar closed cutting pliers closed cutting pliers head device

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, especially a high-frequency bipolar closed cutting forceps closed cutting forceps head device, which can be used in various clinical departments to close and cut blood vessels, lymphatic vessels and suitable electrode jaw size bundle of tissues. The instrument is specifically designed for tissue and vessel closure cutting in laparoscopic and open surgery. Background technique [0002] At present, the monopolar high-frequency electric knife uses a circuit to cut and coagulate the tissue. This circuit is composed of a high-frequency oscillator and amplifier in the high-frequency electric knife, the patient, connecting wires and electrodes. In most applications, active wires and electrodes are used to output the current to the surgical site. This monopolar cutting method uses the patient as an electrode of the access, and it is easy to apply excessive high-frequency energy to the non-p...
