Description
Technical field
The present invention relates to field of surgical, more particularly to a kind of Thyroid Surgery bipolar electric with airsetting gel coating
Solidifying tweezer.
Background technique
Bipolar coagulation forceps are frequently used in thyroid operation, and more and more energy instruments are applied to thyroid gland in recent years
In operation, and recurrent laryngeal nerve in thyroid surgery and superior laryngeal nerve damage after occur hoarseness, drinking-water choke cough, have a low and deep voice
Etc. complication be always the hot spot paid close attention in industry.Analysis finds that the lateral heat conduction of energy instrument causes neurotrosis
One of the major reasons.Electric knife is most traditional electrosurgical unit, and principle is to utilize burst length, extremely short high-frequency current
Cause the ion in tissue to shake the thermal energy of generation in viscid body fluid and work.The highest wink of high-frequency electrical cutter head
Between temperature up to 400 DEG C, lateral heat loss caused by operating process is hurt range and is difficult to control accurately, especially Thyroid Surgery essence
Inconvenience is applied in thin operation.Bipolar coagulation technology completes entire circulation by 2 electrodes using electric current, thus to 2 electricity
Tissue between pole generates fuel factor, reaches hemostasis and cutting effect, but a variety of bipolar coagulation forceps and bipolar multi-functional in the market
The tweezers point such as dissector is mostly the ingredients such as simple metals or alloy, advantageous in terms of accurate operation, but there are still lateral heat loss
The problem of hurting.For ultrasound knife at present in Thyroid Surgery field using more and more extensive, ultrasound knife makes tissue egg by mechanical oscillation
White matter gasification, to achieve the effect that hemostasis and cutting, caused structural stress and the generated temperature that rubs send out cutter head
Heat, more and more ultrasound knifes will cause recurrent nerve thermal damage after.Ligasure energy platform is that bipolar coagulation adds
Real-time feed back techniques and smart host technology, tool temperature is low, and lateral heat conduction is relatively small, but in Thyroid Surgery application
In, thicker cutter head cannot achieve fining envelope dissection operation substantially, in recurrent nerve and superior laryngeal nerve protection operation
Also there is inconvenience, in addition its higher cost issues, limits it in the application in Thyroid Surgery field.
And aerogel material is the material based on nanometer titanium dioxide silica aerogel, is formed by special process combining.
It is with high temperature resistant, the performances such as thermal coefficient is low, density is small, intensity is high, environmentally protective, waterproof is nonflammable.Nowadays it is answered extensively
It is indispensable effectively insulating thermal insulation material for fields such as metallurgy, chemical industry, national defence, aerospaces.
Therefore, it is necessary to the advantage and disadvantage of the various common energy instruments in current Thyroid Surgery field be considered, by bipolar coagulation
It is partially fabricated aerogel material coating other than the tweezer point non-dipole contact surface of tweezer, has both retained bipolar coagulation forceps in thyroid operation
Advantage in middle refinement, but solving its potential lateral heat conduction to the greatest extent may be to refreshing on recurrent nerve, larynx
It is damaged caused by through waiting.
Summary of the invention
The object of the present invention is to provide a kind of Thyroid Surgery bipolar coagulation forceps with airsetting gel coating, retain bipolar electric
For solidifying tweezer in thyroid operation in refinement while advantage, solving its potential lateral heat conduction to the greatest extent may
It is damaged to caused by recurrent nerve, superior laryngeal nerve etc..
To achieve the above object, the present invention provides following schemes:
A kind of Thyroid Surgery bipolar coagulation forceps with airsetting gel coating, the bipolar coagulation forceps include: tweezer seat, first
