Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of high-frequency surgery electric knife.
Background technology
Development along with medical skill, advanced high frequency electric knife, be also referred to as " high frequency electro surgical unit ", substituted gradually traditional mechanical operation cutter, compare with traditional mechanical operation cutter, adopt the high frequency electric knife can also blood coagulation when cutting and organizing, can greatly shorten operating time, reduce patient's blood loss and transfusion volume, thereby reduce complication and surgery cost.Its operation principle is: when the high-frequency high-voltage current producing by active electrode tip contacts with human body, tissue heated, realizes the separation of when injected organism tissue and solidify, thus the object that plays cutting and stop blooding.
The pencil of the high-frequency surgery electric knife that used clinically is at present divided head, body and afterbody three parts, and head is metal electric cutter head, and the electric knife head of different model can be installed as required; Body is handle, by shell, be placed in circuit in shell, the circuit controling switch that is installed on outer shell outer wall forms, circuit controling switch comprises coagulation switch and TURP switch; Afterbody is power line.During use, connect with the mains, open respective switch, by metal electric writing of indictments, appeals, etc. high frequency electric that head produces, tissue is carried out to cutting and separating or electric coagulation hemostasis.This high-frequency surgery electric knife pen exists following not enough: 1) in operation process, the tissue of operative site can be produced a large amount of harmful smog by high temperature cabonization, not only can disturb surgical field of view, and can produce harm to health after sucking; 2) in operation, carry out in process, although use shadowless lamp to carry out visual area illumination, but in a lot of operations, owing to being subject to the impact of the factors such as diseased region depth degree, incision site, health shade, light angle, often make the light of shadowless lamp cannot reach operative region, patient cannot carry out operation technique, affects the even safety of operation process, quality; 3) power line of pencil afterbody and pencil are structure as a whole, and power line cannot be reused, change, and have caused the waste of resource.
Summary of the invention
Goal of the invention: this utility model object is for the deficiencies in the prior art, and a kind of high-frequency surgery electric knife is provided, simple in structure, easy to operate, can effectively absorb the smog producing in operation process, improved visual area definition, and power line can reuse.
Technical scheme: a kind of high-frequency surgery electric knife described in the utility model, comprise main frame, operation electrode and loop electrode, described operation electrode is connected with main frame respectively with loop electrode,
Described operation electrode comprises cutter head, knife bar, hand-held sleeve pipe and power line, and described cutter head and power line are detachably installed on respectively the two ends of knife bar; Described knife bar is fixed in hand-held sleeve pipe, between the outer wall of described knife bar and the inwall of hand-held sleeve pipe, there is annular gap, described annular gap is opening near one end of cutter head, one end sealing near power line, described hand-held sleeve pipe is provided with suction hole near one end of power line, and described suction hole is connected with getter device by conduit; One end that described knife bar connects cutter head is provided with several miniature LED shadowless lamps.
Further improve technique scheme: described knife bar consists of shell and the integrated circuit being placed in shell, and the outer wall of described hand-held sleeve pipe is provided with the gauge tap of controlling integrated circuit in knife bar.
Further: described miniature LED shadowless lamp is surrounded on the surrounding of cutter head and is uniformly distributed.
Further: the circuit part of described LED shadowless lamp is placed in the shell of knife bar, and shadowless lamp switch is installed on the outer wall of hand-held sleeve pipe, the power line of its power line and high-frequency surgery electric knife plying.
As preferably: described hand-held sleeve pipe is insulated sleeve, and its length is less than or equal to the length of knife bar.
Beneficial effect: (1) is in operation process, a large amount of harmful smog that the tissue of operative site can be produced by high temperature cabonization, can absorb by the annular gap between hand-held sleeve pipe and knife bar, suction hole, conduit and getter device, improved surgical field of view, got rid of it healthy generation of medical personnel endangered.
(2) the miniature LED shadowless lamp that is surrounded on the surrounding of cutter head can be followed cutter head and be arrived any operative region, has improved visual area definition.
(3) detachable power line, can reuse, and has saved resource.
