Abstract
The utility model discloses a water guidance electric knife, which comprises an electric knife core. The electric knife core is electrically connected with a corresponding output end of an external high frequency generator through an electric coagulation switch and an electric incision switch, the electric knife core is hollow, the upper end of the electric knife core is communicated with an external transfusion device for feeding water solution, and an opening of water seepage is arranged at an electric knife core head of the electric knife core. Based on an ordinary metal electric knife, the interior of the electric knife core of the water guidance electric knife is hollow for water guidance, the opening arranged at the head of the electric knife core is used for water seepage, excessive heat generated in electric coagulation for tissues is brought away by means of evaporation of seeping water, heat no more than 100 DEG C is generated and transferred on the surfaces of the tissues, and thereby the problem that the ordinary metal electric knife is poor in blood coagulation effect due to over carbonization and/or insufficient carbonization thickness in electric-coagulative hemostasis is solved. Compared with expensive ultrasonic scalpel equipment and radio knife equipment, the water guidance electric knife is simple in structure and low in cost.
Description
Technical field
This utility model relates to a kind of surgical operation and dissects and hemostatic device, the especially electric knife that can seep water.
Background technology
After parenchymal viscera such as surgical operation such as liver partly excises, all need the processing of stopping blooding of organ section.At present, organ section hemostatic way there are seam bundle, ultrasound knife technology, radio-frequency technique, high frequency electric or the like.These methods all relate to blood capillary and little blood vessel sealing technique, and its centre joint is pricked and belonged to the physical technique sealing, can only handle the point-like active hemorrhage.Ultrasound knife makes tissue pulverize cutting by the mechanical energy of conduction supersonic frequency, and the heat that produces during simultaneously with the tissue friction makes the histone coagulation, and ultrasound knife chorista effect is better, does not have the function to the wound surface blood coagulation, and costs an arm and a leg.The principle of radio-frequency technique is by radio-frequency current (ion in 460~500kHz) the exciting electrode surrounding tissues and polar molecule (as hydrone), it is shaken at a high speed and rub, then be converted into heat energy, in the extremely short time, produce 80 ℃~100 ℃ high temperature, thereby histone is solidified or necrocytosis, the advantage of radio frequency knife is that tissue coagulation thickness is fine, but radio frequency itself does not possess the function of chorista, need by other technology chorista, and cost an arm and a leg, improved surgery cost greatly.The high frequency electric method heats destination organization by produce high frequency electric between electrode and tissue, to produce drying, vaporization and carbonization effect, make the histone coagulation, this method is most widely used clinically at present hemostatic technique, it comprises common metal electric knife and argon cutter, the electric knife of common metal electric knife connects an outfan of external high frequency generator, human body connects another outfan of described external high frequency generator, by between electric knife and tissue, producing high frequency electric destination organization is heated, to produce drying, vaporization and carbonization effect, it is higher that electricity coagulates the temperature that produces, often make the wound tissue escharization, being covered in tissue surface by eschar stops blooding, shortcoming is that the blood coagulation effect is bad, during to the petechia blood coagulation faster of hemorrhage speed, eschar promptly stops conduction after reaching certain thickness, eschar thickness possibly can't closely cover bleeding tissue, producing smog simultaneously in the hemostasis can be harmful to patient and medical worker, at present existing a kind of multi-functional electric knife can have the function that attracts waste gas simultaneously, because common metal electric knife low price is still the most general operation separation and the hemostatic device of use clinically at present; The argon cutter is to utilize argon as conducting medium, in operation, can reduce the wound surface temperature, reduce the oxidation, carbonization (smolder, eschar) of damaged tissue, therefore the eschar effect is better than the common electrical cutter, but because eschar thickness is thinner than the metal electric knife, therefore better to the chronic oozing of blood effect of big wound surface, relatively poor to the active hemorrhage effect, and the argon cutter need adopt special main process equipment and argon, costs an arm and a leg.
The utility model content
But the purpose of this utility model provides a kind of water guide electric knife, has both had the function of chorista, has good blood coagulation effect again.
For achieving the above object, this utility model can be taked following technical proposals:
But this utility model water guide electric knife, comprise the electric knife core, the electric knife core coagulates switch by electricity respectively and the TURP switch is electrically connected with the corresponding outfan of external high frequency generator, described electric knife in-core portion hollow, the upper end is communicated with the outside transfusion device of supplying with water liquid, and the electric knife core head of electric knife core is provided with the opening that is used to seep water.
Described electric knife core upper end is provided with water inlet.
Described electric knife core is provided with housing outward.
Described electric knife core is provided with insulating sheath outward.
Described insulating sheath is provided with housing outward.
The upper/lower terminal of described electric knife core all is arranged on outside the housing.
But water guide electric knife described in the utility model, on the basis of existing common metal electric knife, the electric knife core is arranged to hollow, be used for water guide, and opening is set at the electric knife core head, be used for infiltration, when organizing electricity to coagulate, the electric knife core seeps water with certain speed from the electric knife core head under the control of described transfusion device, described infiltration is by the unnecessary heat of evaporator strip leakage of electricity electric current generation frequently, thereby be no more than 100 degree in tissue surface generation and conduction, it is the temperature of the boiling point of water, this temperature make just the histone degeneration solidify and can carbonization incrustation, simultaneously, continue heat conduction by water with contacting of tissue, sustainable the conducting to of heat organized the depths, so the degree of depth that histone solidifies is better, solved existing common metal electric knife owing to organizing the electric coagulation hemostasis carbonization excessively and/or the bad problem of blood coagulation effect that exists of carbonization thickness low LCL; This utility model is arranged to hollow with electric knife in-core portion, makes the electric knife core have the water guide function concurrently, and is simple in structure, with low cost, more is applicable to industrialization.
