Abstract

The invention provides a water injection device of a medical operation electrode and a manufacturing method of the water injection device, and particularly discloses a water injection device of a double-pole operation electrode, which can be applied to histological anatomy or tissue drying or tissue ablation or low-temperature hemoglutination. The water injection device consists of a water inlet tube joint of an electrode, a water inlet catheter, an electrode internal pipeline and a tool nose water outlet, wherein the water inlet tube joint is matched with the outer conical joint of a medical infusion set; and the tool nose water outlet is formed in the back part or close to an electrode working end. The water injection device has the beneficial effects that the electrode is more suitable for the practical requirements of different types of surgical operation; and meanwhile, physiological saline is conveniently guided to a surgical treatment position simultaneously in an oriented way on the double-pole electrode, so that the working effect of the double-pole electrode is improved greatly, surgical operation is simplified, the treatment function of the electrode is brought into play to the maximum extent, the operation effect and safety are improved, and side injuries in a treatment process are controlled and reduced to the maximum extent.

Description

Technical field [0001] The invention relates to a water injection device on a medical surgical electrode and a manufacturing method, in particular to a water injection device used on a bipolar surgical electrode that can perform tissue dissection, tissue drying, tissue ablation, or low-temperature coagulation during surgery. Background technique [0002] At present, known surgical electrode devices, one type is that the excitation electrode contact and the return electrode contact are separated, the needle-shaped excitation contact treats the lesion, and the sheet (electrode sheet) return contact is attached to the patient. It is a monopolar electrode. The other type is to provide an excitation contact and a current return contact at the workpiece end at the same time, which is called a bipolar electrode in the medical profession. The electric field does not pass through the human body when the bipolar electrode is working, so it has more advantages in use safety. [0003]...
