The appearance of binocular surgical microscopes in the 60's of the 20 th century became the hallmark of the beginning of modern otology, and ear microsurgery and lateral cranio-basilar surgery formally entered the rapid development period.
In recent years, due to the development of high-definition cameras and high-quality optical components, the application of the ear endoscope surgical technology in middle ear, inner ear and lateral skull base operations is promoted, and a set of complete ear endoscope surgical technology system is formed. The ear endoscope mainly exposes lesions through a natural channel and has a unique minimally invasive incision; the conical visual field is wider than that of a microscope, so that the deep structure can be observed more advantageously; the wide-angle visual field can also effectively reduce bone abrasion and can keep a normal structure as much as possible. However, otoscopes also have significant drawbacks, above all the problem of one-handed operation, which is significantly inferior to two-handed operation in the case of lesion clearance, especially fine manipulation; in addition, the related anatomical structure of ear surgery is deep, and the peripheral important nerve vessels are dense, which is different from the operation of nasal department and throat ear endoscope. The external auditory canal of the natural pore canal through which the ear endoscope passes is of a bone structure, is narrow and has a limited extension range, and cannot accommodate more surgical instruments to operate simultaneously. And in the narrow lacuna, bleeding has a greater negative effect on the surgical field, so that it is also an important bottleneck limiting the widespread development of endoscopic ear surgery.

In the otoendoscopic surgery, not only is the precision requirement high, but also the cutting, coagulation, digging, poking and other operations are required to be carried out on the target part. The ear endoscope operation can rapidly cut, melt and coagulate to stop bleeding by the micro low-temperature plasma electrode, so as to eliminate the defect that the visual field is affected by matching with the liquid injection unit, the suction unit and the like, and can also use the structural characteristics of the ear endoscope operation to carry out the operation actions of digging, digging and the like, so that the waste generated by the ear endoscope operation is stripped, and the waste is sucked out of the body along with the physiological saline.

Aiming at the key technical problem of the ear endoscope surgery, the invention applies a brand-new ear endoscope surgery operation mode, well makes up the defects of the ear endoscope surgery, and ensures that the ear endoscope surgery becomes clearer, simpler, more convenient and smoother. In this mode, the operator can put the sheath of the ear endoscope on the hand-held ear endoscope, and the normal saline can be continuously pumped into the sheath at a certain pressure and flow rate. Almost all operations under the otoscope can be carried out in continuously exchanged physiological saline, a small amount of bleeding and generated bone meal and the like in the operation are flushed out by running water with certain pressure and are sucked out in time by a suction tube placed in a concha cavity, so that the cleanness of a lens and the field of the operation are kept all the time, and the smoothness and the safety of the operation are greatly improved.
The narrow and small characteristics in scope operation pore have been operated to the make full use of this mode novelty, and the physiological saline that lasts the flow is in constrictive space, and its certain pressure and velocity of flow can be fast with filths such as bloodstain and bone meal that influence the field of vision from the operation chamber, and the scope mirror surface under water can remain clear throughout, has avoided the puzzlement that traditional mode cleaned the camera lens repeatedly, also need not to use the aspirator in the operation region for the operating space of other apparatus is more abundant.
The mode can be widely applied to the lateral skull base operations such as ear endoscope tympanic membrane repairing operation, ear endoscope tympanoplasty, ear endoscope surface nerve decompression operation, and the whole ear endoscope vestibular nerve sheath tumor resection. In clinical practice, even in this mode, the following problems still exist:
1. the more obvious arterial hemorrhage, the water flow has no time to wash away the red blood cells, the visual field definition under the otoscope can still be influenced to a certain degree, and the fine degree of the operation can be influenced in the fields of ear microsurgery and lateral skull base surgery.
2. When the operation is performed for a period of time because other operations need to pause flushing, and the operation cavity is entered again, more blood clots are often adhered in the operation field, the operation cannot be performed through flushing, and other instruments are required to be used for grabbing, so that the overall smoothness degree of the operation is influenced.
3. After a skin flap is cut and pathological changes are clamped by a conventional otology microscopic instrument, irregular soft tissues at the edge of a local wound surface can float in running water under the mode, and certain adverse effects are formed on the operation field and operation.
4. Because of the narrow operation space, the current clinical hemostatic devices can not meet the requirements of fine otoendoscopic surgery.
Repeated tests show that the problems can be well solved by further combining the micro low-temperature plasma unit with the mode.
The principle of the low-temperature plasma radio frequency ablation technology is that low-frequency radio frequency energy is converted into electrolyte (such as physiological saline), a plasma thin layer is formed between a plasma electrode and target tissues, and charged particles in the plasma thin layer dissociate molecular bonds in the target tissues under the acceleration of an electric field, so that the coagulation, necrosis and cutting of the tissues are achieved. The plasma electrode is not directly contacted with a target tissue, but is indirectly cut by a plasma thin layer, and the micro-low-temperature plasma electrode is continuously washed by the electrolyte, so that the working temperature of the micro-low-temperature plasma electrode is only 40-70 ℃, and the micro-low-temperature plasma electrode is greatly lower than that of equipment such as electrotome bipolar coagulation. Due to the advantages of low-temperature cutting and electric coagulation hemostasis, the plasma electrode is widely applied to operations of ear, nose, throat, head and neck surgery. Among them, the more mature are adenoidectomy of the throat, tonsillectomy, and minimally invasive surgery for tumors in the head and neck, nasal sinuses, which have received attention in recent decades.
However, plasma electrodes are a blank in the otology field. The main problem lies in that the currently commonly used plasma electrode with cutting, ablating and hemostasis functions needs to be internally provided with an irrigation pipeline and a suction pipeline for providing an ionic solution, so that the size is large, the thinnest diameter exceeds 3.5 and is almost equal to the diameter of an external auditory canal, and the requirement of fine operation of ear surgery cannot be met.
The invention is a new system and a new mode generated by combining a micro low-temperature plasma unit with the mode, and all operations are almost performed in circulating physiological saline, so that saline water inlet and outlet pipelines which are required by the traditional plasma electrode can be eliminated, and the basis for realizing the miniaturization of the plasma electrode is provided (namely, the plasma electrode can be ensured to be normally excited under the operation environment while the size is reduced). Therefore, the plasma electrode under the mode is miniaturized, is designed into a shape suitable for being operated in a narrow auditory canal, and is matched with an ear endoscope and the like to form a set of novel ear endoscope operation micro-low temperature plasma operation system. This operation system will hardly carry out the region of plasma electrode operation in the past for the first time and become the region that can operate in a flexible way, has realized the unity of cutting with the hemostasis function, also further keeps the art field clear from simply washing passively, upgrades to initiatively stanch and wash the dual fail-safe mode passively, makes the ear endoscope operation have safer guarantee, and more clear graceful field of vision also makes the contribution for further perfection of ear endoscope surgery system and development.
