Description
Technical field
This utility model belongs to the electrosurgical unit technical field of structive sursery operation usefulness, is specifically related to a kind of animal specific high frequency electric knife.
Background technology
High frequency electric knife (high frequency electro surgical unit) is a kind of electrosurgical unit that mechanical scalpel is organized cutting that replaces.
According to the principle of medical physics, when high frequency electric passed through biological tissue, because the electrical pulse time of each vibration is extremely short, ion was difficult to cause migration, only vibrated in being rich in the body fluid of viscosity, because of heat is given birth in friction.High frequency electric knife utilizes high frequency electric to make by this heat effect of biology.In the structive sursery operation, the active electrode of high frequency electric knife reaches animal with high frequency electric, and is very high with electric current density on the contacted animal tissue of the active electrode respective point, produces enough heats on regional area, thereby controlled disorganize is to reach desired therapeutic effect.The clinical effectiveness of high frequency electric knife mainly by the geometry of electrode, determines the amplitude of high frequency electric, waveform and action time.Cutting and blood coagulation are the high frequency electric knife treatment effects of generally acknowledging, action principle is as follows; The effect of cutting: the edge of the active electrode of high frequency electric knife edge of a knife during especially as scalpel, surface area is very little.When with its contact tissue, electric current with high density current to tissue.Tissue is resistive, and the temperature of the tissue in the electrode edge limited range rises rapidly and strongly, makes the very fast evaporation of Cell sap in this place's group knowledge, reaches the purpose that tissue is agilely cut, and its effect is especially as sharp cutter is scratched tissue.Successive undamped sinusoidal current can produce extraordinary dissection, but does not almost have any hemostatic function.The effect of blood coagulation: near the very fast evaporation and tissue is subsided when cutting of the cell the electrode, but temperature does not rise to the degree that is enough to make the tissue protein degeneration.Blood coagulation then is by sealing tissue, thereby stops liquid to ooze out or hemorrhage, and two kinds of technology are generally arranged: dry and fulgerize.Under the situation of these two kinds of technology of use, heat all flows into tissue from the position that applies electric current, and in the close finite region of electrode, the temperature of tissue rises to is enough to reach dry, or disorganize, but does not have evaporation.Drying only takes place when electrode contacts with tissue tight, and electric current diffuses into tissue with appropriate density, raises the temperature to the degree that is enough to destroy cell.Comparatively speaking, the waveform of electric current is unimportant to drying effect, and the contact area of electrode and tissue must be enough big, and electric current or power density must be enough low, so just can avoid the evaporation of superficial tissue layers Cell sap.High frequency electric knife is the duty that is in low output voltage, low output impedance when being used to organize drying.High frequency electric knife has two kinds of main mode of operations: one pole and bipolar.In monopolar mode, cut and solidified structure with a complete circuit, this circuit is by the high frequency generator in the high frequency electric knife, negative plate, lead and electrode are formed in succession.In most application, electric current passes organism by active wires and electrode, is returned the generator of high frequency electric knife again by negative plate and lead thereof.Can destroy the heating effect of the high frequency electric knife of pathological tissues, be not to be caused by heating electrode or cutter head, as electric cautery.It is that high frequency electric with high current density gathers together, and directly destroys the tissue that is under contacting a bit with the active electrode tip.When contacting with active electrode or the temperature of adjoining tissue or cell when rising to protein denaturation in the cell, just produce blood coagulation.Bipolar coagulation is that two tips by bipolar forceps provide high-frequency electrical energy to body tissue, makes the blood vessel dehydration between the bipolar forceps two ends and solidifies, and reaches the hemostatic purpose.Its sphere of action is only limited between the tweezers two ends, and is much smaller more than the one pole mode to the degree of injury and the coverage of body tissue, is applicable to little blood vessel (diameter＜4mm) and oviducal sealing.
The application of high frequency electric knife in the structive sursery operation at present mostly is the monopolar operation pattern, and in the minor operation of handling less pathological changes or parasitic tissue, the wound face of generation is bigger.In addition also can't implementation of class like blood vessel, the closed surgery of tubular tissues such as fallopian tube, so range of operation is limited.
The utility model content
Big and the limited shortcoming of range of operation of wound face when solving present animal with the minor operation of high frequency electric knife, this utility model provides a kind of animal that has one pole and bipolar two kinds of mode of operations concurrently to use high frequency electric knife.
The technical solution that realizes above-mentioned purpose is as follows:
Animal specific high frequency electric knife device comprises that adjustable stabilized voltage supply module 2 and output are selected and grade display module 5 connects to form supply voltage regulatory function piece, and mode of operation selects module 1 and supply voltage regulatory function piece to connect and compose the amplitude-modulated wave generator of high-frequency signal; High frequency generator 3 connects foot-operated control signal unit 7 and work indicating member 6 constitutes the high frequency generator controller; Amplitude-modulated wave generator and high frequency generator controller connect to form high-power high-frequency amplitude-modulated wave generator; List/bipolar electric knife selected cell 4, Single-pole electric knife 8, bipolar coagulation tweezers 9 and negative plate 10 are formed the output function piece of high frequency electric knife; The output function piece is connected with high-power high-frequency amplitude-modulated wave generator.
Use high frequency electric knife with respect to the common animal that the monopolar operation pattern is only arranged, the useful technique effect of this utility model embodies in the following areas:
1, keep that conventional animal is fast with the high frequency electric knife cutting speed, haemostatic effect good, the advantage of simple to operate, safe ready.
2, clinically, when adopting the bipolar operation pattern of high frequency electric knife, can not need the silk thread hemostasis by ligation, this shortens operating time greatly, reduces the animal blood loss, thereby reduces complication, helps the healing of wound.
3, when carrying out these diffusivity oozing of blood positions operation such as liver, spleen, thyroid, mammary gland, pulmonary, the bipolar operation pattern of high frequency electric knife directly acts on the petechia, and Blood clotting is better, and wound face is littler.
4, range of operation is bigger, can well be applied to all kinds of operations, and for example treatment operation is as hernia repairing, tumor resection etc.; Economic operation, as castrate, cattle gallbladder Calculus Bovis cultivating, zygote transplation etc.; Plastic operation is as the entropion and the shaping of turning up, skin transplantation etc.; The test operation is as organ transplantation, gastrointestinal fistulation, obduction etc.

When these electrons are set in motion in the same direction an electric current (I) is produced that is measured in amperes. Opposite charges on the ends of the conductor cause the elec-trons to flow in one direction toward the positive terminal. The differ-ence in potential between the positive and negative poles provides the electromotive force (voltage) to drive the current through the conductor (Figure 1). | |
