Bipolar plasma operation electrode for maxillofacial surgery

Technical Field

The utility model relates to a medical treatment field particularly, relates to a jaw face surgery is with bipolar plasma operation electrode.

Background

Low temperature plasma technology has been widely used in ear, nose, throat and head and neck surgery and is noted to have good minimally invasive advantages. It can form a highly concentrated plasma steam sheath around the electrode, and break the molecular bonds that constitute the cells of the target tissue at lower temperatures (40 ℃ -70 ℃) to rapidly break down the cells in the target tissue into carbohydrates and oxides. The plasma steam sheath layer has extremely small range, so the effect of the plasma steam sheath layer is accurately controlled on a tissue basal layer contacted by the electrode, and the plasma steam sheath layer has no great influence on surrounding and deep healthy tissues, thereby having the characteristics of smaller operation wound, less bleeding, light pain and quick recovery.

The technology is applied less in the maxillofacial surgery, the maxillofacial surgery often needs to be operated in a narrow space, tiny pathological changes are cut off and are drilled for ablation treatment, and the traditional plasma electrode is thick in diameter and large in cutting width, so that fine operation is difficult to perform under the operation conditions. In the process of cutting off the anterior attachment and part of the lateral pterygoid muscle of the joint disc in the temporomandibular joint mirror disc reduction operation, the joint disc is often required to be peeled off downwards and backwards so as to see important anatomical structures such as nerves, blood vessels and the like and prevent the electrodes from cutting off the structures. The existing low-temperature plasma electrode is not strong enough, and cannot well strip tissues, and the joint disc needs to be stripped by replacing a puncture sleeve, so that the operation steps are increased, and the operation time is prolonged.

An effective solution to the problems in the related art has not been proposed yet.
