Adopt above -mentioned structure, the effectual advantage of low temperature condition with the observation of still being convenient for that has realized accuracy, safety, the convenience of performing the operation.
Description
Technical field
This utility model relates to a kind of medical plasma operating theater instruments, is specifically related to the low-temperature plasma scalpel of a kind of applicable Otorhinolaryngologic operation.
Background technology
The ultimate principle of low-temperature plasma scalpel is the energy utilizing bipolar radio frequency to produce, make the target tissue cell rapid dehydration between radio frequency acusector the two poles of the earth, cause it to decompose and obtain the volume reduction of effective tissue and eradicating efficacy, i.e. bipolar radio frequency makes to be formed between electrode and tissue plasma thin layer, layer intermediate ion is by electric field acceleration, and transfer energy to tissue, cellular elements associative key is opened at a temperature of 60-80 DEG C, making the cell disintegration in target tissue is carbohydrate and oxide, cause tissue coagulation downright bad, downright bad tissue loss or generation cicatricial contraction.Simultaneously because of the heat effect of electric current, blood vessel can be made to shrink rapidly solidification, the structure design of radio frequency needle uniqueness can make treatment be positioned accurately at interstitial lamella, (built-in electrode is placed in the nearly needle point position, top of acusector to avoid the damage to tissue surface to greatest extent, sphere of action is confined to around acusector, not damaging tissue surface epithelium and mucosa, be accurately located at interstitial lamella, histoorgan surface keeps complete).Automatic energy control function, it can be ensured that excessive radio-frequency (RF) ablation effect will not occur at target tissue region.
Otorhinolaryngologic operation use plasma scalpel primarily to polyp ablative surgery, owing to the otorhinolaryngology of human body mostly being soft tissue and sense organ cell, high temperature can destroy the function closing on cell tissue, need to control its low temperature menisectomy, simultaneously because such operation mostly is tissue outer operation operation, and too much body fluid can affect the operability of operation.
Summary of the invention
This utility model provides a kind of reasonable in design, the plasma otorhinolaryngologicoperating operating knife that operation temperature is low, its needle-like designs and uses drain as supplementary means, effectively achieves cryogenic conditions to be still easy to the advantage observed, it is achieved that accurate, the conveniently, safely property of operation.
The technical solution adopted in the utility model is as follows:
A kind of plasma otorhinolaryngologicoperating operating knife, it is made up of knife bar assembly, electrode body and handle, it is characterized in that: described scalpel is an electroded spicule, knife bar assembly is a hollow pipe, the front end of this hollow pipe is extended electrode base, electrode and draining hole it is provided with on electrode base, hollow pipe rear end is provided with power line and negative-pressure suction pipe assembly, power line and negative-pressure suction pipe assembly are through handle of a knife and hollow pipe, handle of a knife is made up of insulant, there is a fixture in hollow pipe and handle of a knife junction, be used for fixing handle of a knife and knife bar assembly.
In detailed description of the invention, described hollow pipe is stainless steel.
In one embodiment, hollow pipe is a curved arcuate structure near electrode tip, and it wraps up internal electrode pedestal one end.
In one embodiment, bending at an angle between hollow pipe and steel pipe fixture.
In another embodiment, described negative-pressure suction pipe assembly is hard PVC water injection pipe.
In still another embodiment, hollow pipe is steel matter with the fixture of handle of a knife junction.
Using said structure, it has the beneficial effect that
This plasma otorhinolaryngologicoperating operating knife, its needle-like designs and uses drain as supplementary means, effectively achieving cryogenic conditions to be still easy to the advantage observed, it is achieved that accurate, the conveniently, safely property of operation.
