Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of throat's low-temperature plasma cutting ablation needle knife.
Background technique
Vocal cords benign proliferative lesion includes polyp of vocal cord, vocal nodule, vocal cyst, vocal cords times gram layer oedema, vocal cords
The tumors type lesion such as papilloma is to lead to the most common cause of disease of hoarse voice, clinically takes operation to control tumor type lesion more
It treats.The advantages of mainstream treatment method is to use supporting laryngoscope operation removal lesion tissue under general anesthesia at present, general anesthesia menisectomy is disease
Human vocal band remains static, easily operated, cooperates microscope and laser, performs the operation more accurate, the disadvantage is that general anesthesia risk is big, has
A little risks can be fatal or disable, and there are also injury of teeth, the tearing of pharyngeal mucous membrane, tongue injury, lingual nerve injury, the bad palms of excision extension
The risks such as hold.Case lesser for lesion extracts lesion group using laryngeal biopsy forceps using electronics (fiber) laryngoscope menisectomy
It knits, this method can allow patient to pronounce immediate assessment range of operation and effect during surgery, it can get preferable therapeutic effect,
Advantage is that operation can be completed under local anaesthesia, it is possible to prevente effectively from the risk of above-mentioned general anesthesia operation, the disadvantage is that the surface of a wound holds when operation
Easy bleeding, influences surgical effect.
Collation surgery art utilizes the energy of low-temperature plasma radio frequency, with lower temperature (40-70 DEG C) Lai Jinhang
The ablation of tissue is cut off, small to tissue damage.Compared to laryngeal biopsy forceps, the low-temperature plasma cutting ablation knife of throat is applied to
The smaller disease surgery of throat under local anaesthesia can use good hemostasis while completing ablation cutting, keep good surgical field of view,
Tissue damage is small but excellent really, and operation safety is high.The low-temperature plasma cutting ablation knife of the throat clinically applied at present is stick
Shape head, does not allow to be fixed easily in active organization, causes damage range big after slippage, and influences operation precision.
Utility model content
The purpose of the utility model is to overcome above-mentioned technological deficiency, a kind of throat's cutting ablation needle knife is provided for smaller sound
Treatment with benign proliferative lesion under local anaesthesia, carries out cutting ablation to pathological tissues under electronics (fiber) laryngoscope,
Accurate positioning, accuracy are high.
The technical solution adopted in the utility model is: throat's low-temperature plasma cuts ablation needle knife, includes mainly casing, connects
Head, first electrode and second electrode, cannula end are fixed on connector, and casing front end is equipped with first electrode and second electrode, the
One electrode be it is needle-shaped, second electrode be ring it is rodlike, be provided between the first electrode and the second electrode by first electrode and second
The insulating element of electrode mutually insulated, first electrode and second electrode are connect through conducting wire with connector respectively, connector and low temperature etc. from
Sub- radio frequency ablation system connection.
The insulating element has round table-like head and cylindrical body, and cylindrical body is inserted into casing front end and casing is solid
Fixed, first electrode is inserted into round table-like head and is fixed with insulating element, and second electrode is sleeved on outside cylindrical body.
The material selection conductive metal or graphene of the first electrode and second electrode, in the non-exposed portion of first electrode
Outside be equipped with insulating layer, the insulating layer can be polytetrafluoroethylene ethylene layer.More preferably, the conductive metal is stainless steel, titanium conjunction
Gold, tungsten alloy, partinium, nickel alloy or Nitinol.
The utility model throat's low-temperature plasma cutting ablation needle knife first electrode be it is needle-shaped, second electrode be ring stick
Shape, acicular first electrode registration and fixed reliable with tissue is difficult to slide, loads in first electrode or second electrode
Voltage, first electrode and second electrode act on pathological tissues, and electricity is formed between first electrode, pathological tissues and second electrode
When flowing back to road, target lesion tissue can be accurately acted on, normal tissue will not be accidentally injured, improve the accuracy and precision of operation,
Making the operation of more vocal cords benign proliferative lesions can complete under local anesthesia, eliminate general anesthesia risk, improve the peace of operation
Quan Xing, treatment cost is reduced.
