Description

Technical Field

[0001] This utility model relates to the field of medical high-frequency electrosurgical technology, and more specifically, to a medical electrosurgical device that can purify smoke. Background Technology

[0002] A medical high-frequency electrosurgical unit is an electrosurgical instrument that can replace a mechanical scalpel for tissue cutting. It heats the tissue by generating a high-frequency, high-voltage current at the tip of its effective electrode, achieving tissue separation and coagulation, thereby achieving the purpose of cutting and hemostasis. A medical electrosurgical unit mainly consists of electrodes for cutting, a handle, wires passing through the handle and connecting to the electrodes, and a main unit. It uses high-frequency, high-voltage current to cut or stop bleeding in the skin or soft tissue.

[0003] For example, patent CN215960232U provides a medical electrosurgical unit with a smoke-absorbing function, including a handle, a blade, a circuit assembly, a button, and a power cord. The circuit assembly is located inside the handle, and the power cord is connected to the circuit assembly inside the handle. The button is located on the handle and cooperates with the circuit assembly. It also includes a connecting assembly and a flexible tube. The flexible tube is connected to the handle via the connecting assembly. The connecting assembly includes a top plate, connecting posts, a bottom plate, and a locking element. Two connecting posts are located on the lower sides of the top plate. The bottom plate is fitted onto the two connecting posts and can move along the connecting posts. The locking element is located on the connecting posts and can be positioned below the bottom plate. The flexible tube and the handle are both located between the top plate and the bottom plate.

[0008] Preferably, the smoke purification tube has several smoke holes at its head near the electrode head, and the smoke holes are evenly distributed on the surface of the smoke purification tube that extends out of the handle.

[0009] Preferably, the inner cavity of the smoke purification tube is provided with a fixed mesh plate, the tail end of the electrode head passes through the center of the fixed mesh plate, and the fixed mesh plate is arranged in a direction perpendicular to the smoke purification tube, so that the electrode head can be arranged parallel to the smoke purification tube.

[0010] Preferably, the tail end of the smoke purification pipe is equipped with a smoke exhaust pipe and a suction pump, and the two ends of the smoke exhaust pipe are respectively connected to the tail end of the smoke purification pipe and the suction pump.

[0011] Preferably, the tail end of the smoke purification pipe is provided with a puncture membrane layer, and the end of the exhaust pipe can be inserted into the smoke purification pipe through the puncture membrane layer.

[0012] Preferably, the end of the wire away from the electrode head extends from the tail end of the handle, and the end of the wire extending from the handle can be connected to a power source.

[0013] Preferably, the tail end of the smoke purification tube or the tail end of the handle is provided with a clip, and the wire can be clamped in the clip.
