Beneficial effect
The present invention with the beneficial effect that present electric knife is compared is:
1. smog stink and the harmful gas that when using electric knife, is produced, conduction blank pipe electric knife head by hollow can thoroughly be sopped up timely, guaranteed operation, made doctor and patient avoid the influence of smog stink and harmful gas, the smog when having guaranteed operation no longer influences operator's the visual field; And to narrow and small profound operative site, elongated conduction blank pipe type electric knife head also can enter easily to cut and coagulate, and siphons away smog easily, has prevented from can not enter narrow and small profound operative site because of the too thick heaviness of smoking port, and the smoking that causes failure; Smog and influence operator's the visual field, the operative failure that further causes.
Straight type or curved blank pipe conduction cutter, to narrow and small crooked position, translation-angle cuts operation with fixed attention easily.
The body fluid blood that produces when the present invention can also work to electric knife, pus, processing solution, solid impurity etc. aspirate timely, thereby guaranteed the visual field clearly, and dry clean art district, for cutting smoothly of electric knife coagulated, removed obstacle, for the healing of postoperative provides guarantee.
2. dwindled the volume and the weight of the electric knife handle of band smoking function, guaranteed handy when difficulty is imitated big operation technique, the operative region at narrow and small profound position also can easily enter to cut easily and coagulate and siphon away smog.Avoided the incoordination of operating and operative failure or the error that causes by many people.The second conduction blank pipe that the present invention slides and is with, be free to put and take off, and can stretch easily or maintain static, thereby make deep mixed art district, changeable electric knife head is provided, need not frequent replacing electric knife head, and mistaking of causing delays work, shortened the working time of electric knife, for operation provides more convenient.
3. that has improved electric knife cuts efficient with fixed attention; The present invention because of need not many people operate one hand can finish simultaneously cut coagulate, the multinomial work of smoking, imbibition gettering matter, so very the great achievement degree has improved the work efficiency of electric knife, but electric knife handle negative pressure straw completely knocked down irrigation and disinfection, avoided the sterilization dead angle greatly, also can disposablely use, can make things convenient for and take the plug replacing easily apart.
4. saved the quality time of operation
One hand of the present invention can be finished the work that many people just can finish, quality time that the present invention and can be simultaneously cutting field of operation coagulates, so a large amount of clinical operations have been saved in the multinomial work of smoking, imbibition, gettering matter, avoided many people in limited space, many handss intersect that taking and placing smoking facilities and electric knife enter field of operation and the time waste that causes, people such as doctor nurse are in limited space, dodge mutually, and influence normally carrying out of operation.
5. improved the economy of electric knife.
Filter of the present invention or drainage screen, that can effectively cut the end filters out the coal-tar middle oil carbon deposit impurity of smog, thereby avoided life-time service, tar carbon deposit impurity is to the obstruction of negative pressure straw and negative pressure pump etc., and drainage screen bucket and filter can be pulled down replacing or cleaning easily in the negative pressure pipe.
6. reduced the breakdown maintenance rate of electric knife.
Membrane pump do not leak, do not generate heat and can fill superior function that fine granularity material perhaps passes through etc., reduced the breakdown maintenance rate of electric knife, ozone proof membrane pump, avoided aging, the ozone that when electric knife is worked, produces, membrane pump can in and toxic gas and stink in the smog, if any residual gas, the sterilization back of can extending to outdoor or the disinfector is got rid of.
7. insulated thermal insulating layer has improved the security performance of electric knife.
Prevented the accidental injury of electric knife, reduced malpractice normal structure.
8. improved the quality of electric knife.
The luminous body that telescopicing performance is arranged can clearly reach exactly at affected part the electric knife operator, cuts the treatment of coagulating operation, has improved the accurate performance of operation; When telescopic electric knife head is performed the operation with fixed attention in narrow and small profound cutting, can stretch freely.
9. the scope of application and the useful performance of electric knife have been enlarged
(1) the present invention is thrown light on and is used the luminous body socket, can change luminous body easily also can in time sterilize, the conduction of also can stretching in socket luminous body also can change irradiating angle, thereby the visual field to electrotomy provides enough light sources, has avoided the major surgery lamp can not shine the hidden operative site of narrow and small bending.Also can be used as lantern clinically uses.
When (2) needing imbibition to suck blood operation, the body fluid pus is hemorrhage can in time to be sucked away, cuts for electric knife and has paved road with fixed attention.
(3) the broken little solid matter of the function of gettering matter to producing in the operation when doing to bore bone or cutting bone, can in time aspirate and reclaim broken for a short time of the body bone, can insert again and lacks the bone district, for the patient has saved overspending; And can avoid using artificial bone's rejection to endanger.
