Description
Technical field
The present invention relates to a kind of thyroid nodule and the minimally-invasive treatment medical instruments of tumour, more particularly to one kind to be used for first shape
The color ultrasound of gland tubercle and tumour images microwave therapeutic system and microwave radiation probe recognition method.
Background technique
Thyroid nodule and tumour are common disease, frequently-occurring disease, in general population, thyroid nodule palpation recall rate about 4%,
High frequency ultrasound recall rate is up to 20% ~ 60%.Currently, the treatment of thyroid nodule need to distinguish first its histological type belong to it is benign or
Pernicious, wherein the tubercle of about 5%-15% is malignant tumour, and benign thyroid nodules also have the potential of canceration, in addition, to one
A little growths rapidly, generate the tubercle of local compression symptom or can not rule out potential pernicious tubercle, timely treatment is also needed to handle.
For thyroid nodule in need for the treatment of or thyroid tumors, surgical resection is conventional treatments.But
That there are wounds is larger for traditional surgery, it is beautiful to influence, damage normal gland causes hypothyroidism, easily leads to a variety of hands
The drawbacks such as art complication generation.Meanwhile a possibility that thyroid nodule recurrence, is larger, when palindromia, if needing again
Operation, patient body and psychology are difficult to receive.Thyroid operation under hysteroscope is also the Minimally Invasive Surgery occurred in recent years, although
Postoperative neck is considered a kind of by industry without scar, but because operating time is long, subcutaneous tissue release surface is big, postoperative pain is obvious
Scar is small, the biggish operation of wound.Drug thyroid hormone suppression therapy, although can inhibit thyroid nodule to a certain extent
Growth, but there is the risk for causing iatrogenic hyperthyroidism or decline, presently, there are larger disputes.Radioactivity131I is suitable
The thyroid nodule for the treatment of high functionality is closed, but because being not recommended for as first-line treatment side there are adverse reactions such as radioactive damages
Method.
Compared with the above existing treatment method, the minimally invasive ablation thyroid nodule of ultrasound guidance and tumour, targeting
Structures locating is accurate, with strong points, is not necessarily to trachea general anesthesia intubation, small to patient trauma, curative effect is reliable.Currently, thyroid nodule
And the minimally invasive ablation of tumour mainly includes percutaneous Ethanol Injection, laser ablation, RF ablation etc..Percutaneous dehydrated alcohol
Injection therapeutic process is uneven by non-directional disperse, the disperse of dehydrated alcohol and pain is influenced, and cannot once melt completely, usually
It is easy recurrence.In addition, this method is only preferable to capsule tubercle curative effect, to solid nodules or there are the tubercle of reality ingredient, a curative effect
It is inaccurate.Adopting said method treatment, there is the possibility of further open surgery.The thermal ablation therapies such as radio frequency, laser ablation are current
The research hotspot of each internal organs occupying lesion of minimally-invasive treatment, is currently used primarily in the malignant tumours such as liver, lung, kidney and mammary gland and controls
It treats.Pacella in 2000 etc. and Dupuy in 2001 etc. applies laser ablation and radiofrequency ablation therapy postoperative recurrence for the first time respectively
Thyroid cancer.Human thyroid benign nodules mainly are treated using RF ablation and laser ablation in 2005 in the country.Radio frequency
Though clear, minimally invasive with laser ablation curative effect, complication rate still has 3.3%, and wherein major complications incidence is
1.4%, including sound change, brachia plexus injury, tumour rupture and permanent hypothyroidism；Some minor complications occur
Rate is 1.9%, including hemotoncus, skin burn and vomiting etc..These because of the excessively high injury tissue of heating ablation temperature caused by.
Microwave coagulation ablation entity tumor, such as liver cancer, kidney, cancer of pancreas have had more mature experience, but
It is that Microwave Coagulation Therapy thyroid nodule and tumour but rarely have Patent data report.Due to this vitals of thyroid gland, it is located at
Neck, around have important blood vessels, nerve, tracheae, oesophagus etc., heating ablation be easy to cause damage, leads to severe complication,
It is even dead.So the requirement to therapeutic equipments is very stringent in order to reach accurate, safe treatment.
Microwave is a kind of electromagnetic wave, discharges thermal energy by spherical body, can be accurately by the first shape more containing amount of liquid
Gland tubercle and tumour solidification denaturation, necrosis, reach focal ablation therapeutic purposes.Due to thyroid gland organ special critical function with
Position, the tissues such as it and important blood vessels, nerve adjoin closely, careless slightly to cause to damage, and lead to serious consequence, so
Microwave probe (also known as microwave radiation needle) releasability for treating thyroid gland lesion must be precisely controllable.On the other hand, thyroid gland
The effect of tubercle and tumour ablation treating needs monitoring in time and judgement in art, so, previously implement Other Instruments heating ablation
When treating thyroid nodule and tumour, first is that thermal energy release is not easy to be precisely controlled, it is easy to happen complication；Second is that implementing this
Minimally Invasive Surgery must be provided simultaneously with two kinds of equipment of thermal ablation therapy instrument and high-frequency color doppler ultrasound, and there are inconvenient victories, and equipment is too fat to move, palpus
The defects of occupying much room, being also unfavorable for the Technique Popularizing application of medical institutions and deficiency.To solve the above problems, of the invention
Design a kind of color ultrasound imaging microwave therapeutic system, different from existing heating ablation instrument for treating thyroid nodule and tumour, body
Present: 1. treatment systems of the invention have real-time ultrasound monitoring guidance, the accurate release function of microwave energy simultaneously, reach first
The ablation requirement of shape adenopathy stove；2. the microwave pin type radiator in the present invention, has cooling water circulation effect, can precisely emit
Microwave thermal energy, and can control needle body temperature, avoid or reduce because thermal energy it is excessively high caused by severe complication, be particularly suitable for
Blood flow thyroid nodule abundant and tumour ablation；3. two or more microwave actions that different location is nearby arranged in syringe needle disappear
Melting point, to increase the effect of ablation, water cooling microwave radiation probe has the syringe needle of multiple and different models, is imaged according to the color ultrasound
The size for the lesion that unit is shown selects the syringe needle of respective model；4. needle body surface is equipped with scale mark and positioning ring, with control
Into the position of human body；5. alinjection channel is arranged inside needle body, needle body high temperature cabonization is prevented；6. setting storage inside needle body
Device, the number that record microwave radiation probe is used, prevents from being used multiple times；7. apparatus structure novelty, design are unique, save
IC Hardware resource, occupies little space；The assembling of product, debugging and easy to repair, it is safe and convenient to use, it is pushed away convenient for technology
Extensively.
