A kind of bipolar electric knife combination unit of high frequency listTechnical field
The utility model belongs to medical surgical instrument and its preparing technical field, more particularly to a kind of to have single bipolar electric knifeThe bipolar electric knife combination unit of high frequency list of translation function.
Background technology
Electric knife (high frequency electro surgical unit) is a kind of electrosurgical unit for substituting mechanical operation knife to carry out tissue cutting.It is logicalTissue is heated when high-frequency high-voltage current caused by crossing active electrode tip contacts with human body, realizes and injected organism tissue is dividedFrom and solidification, so as to play cutting and hemostasis purpose.
Electric knife is made up of the annex such as main frame and electrotome handle, patient's pole plate, electric knife, floor push.High-frequency electricalKnife has two kinds of main mode of operations：Monopole and bipolar, in monopolar mode, is cut with a complete circuit and is solidified groupKnit, the circuit is made up of the radio-frequency generator in electric knife, in succession patient's pole plate, wire and electrode.In most applicationIn, electric current passes through patient by active wires and electrode, then the generator of electric knife is returned by patient's pole plate and its wire.It is doublePole coagulation is to provide high-frequency electrical energy to body tissue by two tips of bipolar forceps, makes the blood vessel between bipolar forceps both endsIt is dehydrated and solidifies, reaches the purpose of hemostasis.Its sphere of action is only limited between tweezers both ends, to the degree of injury of body tissueIt is much smaller more than unipolar fashion with coverage, suitable for thin vessels (diameter<4mm) and fallopian tubal closing.It is therefore bipolarCoagulation is used in the more fine operations such as cranial surgery, microsurgery, ENT dept., gynemetrics and hand surgery.
Single-stage electric knife and bipolar electric knife play different effects in different operation demands, and both can not mutually substitute,Sometimes need successively to use two kinds of electric knifes, but because operation limits, each monopole changes the bipolar or bipolar Single-pole electric knife that changes and is required for curingLife is exchanged for another electric knife using the electric knife of completion from patient's body taking-up and gets involved in patient's body, this repeatedly intervention againThe mode that patient's body changes electric coagulating apparatus repeatedly have impact on procedure efficiency；And electric knife easily carbon deposit, electric knife in surgical procedureWithout clear charcoal function, so as to influence operation and postoperative healing.
In view of disadvantage mentioned above, the design people actively innovates, and a kind of new there is single bipolar electric swivel to change to work outThe bipolar electric knife combination unit of high frequency list of function.
