Abstract
The invention discloses a water conduction electrocoagulation hemostatic cutter, comprising a shell and an electrocoagulation hemostatic cutter core arranged in the shell. The electrocoagulation hemostatic cutter core is electrically connected with the output end corresponding to an external radio-frequency generator respectively through an electrocoagulation switch and an electricity cutting switch; the head of the electrocoagulation hemostatic cutter core extends out from the lower port of the shell; the shell is internally provided with a water conducting device used for seeping water from the lower port of the shell; the water inlet on the water conducting device extends out from the shell and is communicated with a water delivery device which supplies water fluid to the external part and controls the water fluid flow. In the water conduction electrocoagulation hemostatic cutter of the invention, as the water conducting device which can seep water is increased on the basis of the common metal electrotome; the surplus heat generated in electrocoagulation is taken away through steam of seepage water, thus generating and conducting the temperature no more than 100 DEG C on the tissue surface, and solving the problem that the hemostatic effect of the common metal electrotome is not good because of excessive carbonization thickness and/or insufficient carbonization thickness of electrocautery. Compared with the expensive ultrasonic scalpel device and radio frequency knife device, the water conduction electrocoagulation hemostatic cutter has simple structure and low cost.
Description
Technical field
The present invention relates to a kind of surgical operation and dissect and hemostatic device, especially a kind of water conduction cutter that stops blooding with fixed attention.
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 common metal electric knife, electric knife connects an electrode terminal of external high frequency generator, human body connects another electrode terminal 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.
Summary of the invention
The purpose of this invention is to provide a kind of water conduction cutter that stops blooding with fixed attention, both had the function of chorista, have good blood coagulation effect again, and cost is low.
For achieving the above object, the present invention can take following technical proposals:
