[0003] The existing high-frequency electrocoagulation hook uses the hook head to separate the tissue that needs to be cut or coagulated first, and then stirs it up, and then energizes to achieve the purpose of cutting or coagulation. However, in the denser tissues of nerves or blood vessels, the hook head The front end of the cutting machine cannot separate the cut tissue from the non-cut tissue, so it is easy to touch the nerve or blood vessel when the power is on, causing accidental injury to the nerve or blood vessel

The invention discloses a high-frequency electrocautery hook for a surgery. The high-frequency electrocautery hook for the surgery comprises an insulated shell, wherein an electric pole is arranged inside the shell in the length direction of the shell; an upwardly-bent hook head is arranged at the end, extending out of the shell, of the electric pole; an electrode terminal is arranged at the other end of the shell; the electrode terminal is electrically connected with the electric pole; a sliding cavity is arranged inside the shell in the length direction of the shell; a pull rod is slidably arranged inside the sliding cavity; a heating body is fixed at the end, near the hook head, of the pull rod; the heating body is arranged corresponding to the hook head. The high-frequency electrocautery hook for the surgery is simple in structure and easy in operation, can select the heating body or the hook head according to different situations for cutting a tissue or stopping bleeding, and is higher in safety and wider in application during use.
Description
technical field [0001] The invention relates to a medical appliance, in particular to a high-frequency electrocoagulation hook used for surgical operations. Background technique [0002] High-frequency coagulation hook is an electrosurgical instrument for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. [0003] The existing high-frequency electrocoagulation hook uses the hook head to separate the tissue that needs to be cut or coagulated first, and then stirs it up, and then energizes to achieve the purpose of cutting or coagulation. However, in the denser tissues of nerves or blood vessels, the hook head The front end side of the machine cannot separate the cut tissue from the non-cut tissue, so it is easy to touch the nerve or blood vessel when the power is ...
