Description
Technical field
The utility model relates to a kind of medical plasma operating theater instruments, is specifically related to a kind of low-temperature plasma scalpel of applicable ear nose larynx operation.
Background technology
The general principle of low-temperature plasma scalpel is the energy that utilizes bipolar radio frequency to produce, target tissue cell between radio frequency acusector the two poles of the earth is dewatered rapidly, cause its decomposition and obtain effective tissue subtract hold and eradicating efficacy, be that bipolar radio frequency makes to form plasma thin layer between electrode and tissue, layer intermediate ion is by electric field acceleration, and energy is passed to tissue, at 60-80 DEG C of temperature, open cellular elements associative key, make the cell in target tissue be decomposed into carbohydrate and oxide, cause tissue coagulation necrosis, downright bad tissue comes off or produces scar and shrinks. While is because of the fuel factor of electric current, can make blood vessel shrink and solidify rapidly, the structural design of radio frequency needle uniqueness can make treatment accurately be positioned at interstitial lamella, (built-in electrode is placed in the nearly needle point position, top of acusector to have avoided to greatest extent damage to tissue surface, sphere of action is confined to around acusector, not damaged tissue superficial epithelium and mucous membrane, is accurately positioned interstitial lamella, and histoorgan surface keeps complete). Automatic energy control function, can guarantee, at target tissue region, excessive RF ablation effect not to occur.
In the operation of ear nose larynx, adopting plasma scalpel is mainly for polyp ablative surgery, in ear nose larynx due to human body, mostly be soft tissue and sense organ cell, high temperature can destroy the function of closing on cell tissue, need to control its low temperature menisectomy, organize outer operation operation because such operation mostly is, and too much body fluid can affect the operability of operation simultaneously.
Summary of the invention
The utility model provides a kind of reasonable in design, the low plasma scalpel of operation temperature, its needle-like designs and adopts drainage as supplementary means, effectively realized the advantage of cryogenic conditions to be still convenient to observe, realized operation accurately, safety, convenience.
The technical solution adopted in the utility model is as follows:
A kind of plasma scalpel, 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 tube, the front end extension of this hollow tube is provided with electrode base, on electrode base, be provided with electrode and draining hole, hollow tube rear end is provided with power line and negative-pressure suction pipe assembly, power line and suction tube are through handle of a knife and hollow tube, handle of a knife is made up of insulating materials, there is a fixture at hollow tube and handle of a knife junction, for fixing handle of a knife and knife bar assembly.
In detailed description of the invention, described hollow tube is stainless steel.
In one embodiment, hollow tube is a curved arcuate structure near electrode tip, and it wraps up internal electrode pedestal one end.
In another embodiment, described suction tube is hard PVC water injection pipe.
In an embodiment, the fixture of hollow tube and handle of a knife junction is steel matter again.
Adopt said structure, its beneficial effect is:
This plasma scalpel, its needle-like designs and adopts drainage as supplementary means, effectively realized the advantage of cryogenic conditions to be still convenient to observe, realized operation accurately, safety, convenience.
Brief description of the drawings
