Description
The present invention relates to a kind of Clinical Surgery bio-medical engineering equipment, can be widely used in operation cut with high-frequency electric scalpel adaptive control process.
As everyone knows, high frequency electric knife is the widely used basic device of clinical section.But the domestic and international so far various high frequency electric knives that use, band needs the doctor rule of thumb, and looks operative incision and genius loci selection electric knife power; Some what is called has the high frequency electric knife of automatic function, also all can not reach to keep the otch electric injury the lightest the requirement that can effectively cut again.Use both at home and abroad electric knife often with the sallow carbonization of otch, organize that the deep is impaired, the situation of dispersive electrode local skin accident burn takes place.In addition, the edge of a knife or jaw are organized very easily that fragment adheres to and need often to remove, and also the influence operation is efficiently carried out smoothly.
The objective of the invention is: design a kind of TURP or electricity efficiently carries out with fixed attention, the adaptive controller for operation cut with high-frequency electric scalpel of the minimum damage of incision tissue of guaranteeing to perform the operation.It can provide enough big electrical power when needing TURP or electricity to coagulate, and finish with fixed attention at TURP or electricity, otch or electricity locate body tissue with fixed attention and bleach and adjust the size of output when dry automatically, to reach the lightest requirements of operation of incision tissue's electric injury, even electric knife rests on former incision in a long time, this place's body tissue can not burnt yet; And when electric knife reach contact new organize the time, electric knife can be exported enough big electrical power automatically again, and along with the body tissue change of state, carries out adaptive adjusting and protection.
Content of the present invention and requirement are: under the high frequency electric effect, biological tissue's impedance has mutually quasi-stationary trend to change (as shown in Figure 1).Under the normal condition, living organism tissue impedance is lower, after high frequency electric effect a period of time, the tissue begin to bleach dry, occur then sallow, until carbonization.During this period, tissue impedance is increasing always, and is dry to sallow process from bleaching corresponding to tissue, and tissue impedance increases very fast, shown in dotted line rising edge among Fig. 1.Impedance slowly increases to organizing shallow table carbonization from sallow subsequently, and after shallow table carbonization occurring, deep tissue is carbonization in succession, and tissue impedance gathers way and becomes big once again.When high frequency power generator was constant pressure source, corresponding living organism tissue impedance changes overall process will be as shown in Figure 2.That is; When high frequency electric affacts the somewhere when organizing, the high frequency electric that flows through this tissue grows out of nothing, shown in rising edge among Fig. 2.When tissue begins to bleach dry when sallow, tissue impedance increases, and corresponding trailing edge appears in electric current, shown in the dotted line among the figure.At this moment, if move forward along otch with cutter head, when touching new organizing, then because new tissue impedance is low, the high frequency electric virtual value that flows through will increase again, that is occur the electric current rising edge again.Henceforth, above-mentioned change procedure will repeat.This shows the high frequency electric virtual value variation of crossing tissue by monitoring stream, just can understand the variation of incision tissue.When the present invention has fully used electric knife that tissue is begun cutting or electric coagulating, the variation characteristics of high frequency electric virtual value rising, through logical process, the control high frequency electric knife is exported with enough big power, guarantees to perform the operation and effectively carries out at a high speed; Utilization incision tissue begins to bleach when dry, the characteristics that the high frequency electric virtual value descends, through logical process, the control high frequency electric knife is only exported enough little power, even to guarantee when electric knife rests on former otch and do not remove, otch also is only limited to the dry state that bleaches, and unlikely appearance is sallow, more can not cause phenomenon local and the deep carbonization; The utilization electric knife cuts forward or electricity coagulates the new characteristics of organizing electric current to rise again, and by logic control, high frequency electric knife recovers enough big power output again, carries out continuously smoothly to guarantee operation.
The present invention is made up of high frequency power generator 1, otch state identifier 2, adaptive controller 3, self adaptation indicator 4, short circuit monitoring protection instrument 5, leakage current monitoring and protection instrument 6 (as shown in Figure 3).Wherein: high frequency power generator 1 can be exported high-frequency high-power by constant pressure source; Otch state identifier 2 can be by the variation of high frequency electric virtual value, the overall process that monitoring incision tissue changes; TURP looked by adaptive controller 3 or electricity carries out with fixed attention smoothly and incision protection does not cause the needs of sallow carbonization, control high frequency electric power changes as required, promptly use electric knife that tissue is begun to cut or the electricity variation characteristics that the high frequency electric virtual value rises when coagulating, through logical process, the control high frequency electric knife is exported efficient TURP or electric coagulate high-power; The utilization incision tissue characteristics that the high frequency electric virtual value descends when dry that begin to bleach, through logical process, the control high frequency electric knife is only exported the unlikely small-power of organizing sallow or carbonization that causes, and cut forward or electricity when coagulating new organizing at electric knife, again recover enough big power output, to guarantee carrying out smoothly of operation.Clearly, the adaptive control action of adaptive controller, dispersive electrode and the caused tissue burn of patient's local skin loose contact are also prevented and protective effect, can significantly reduce the generation and the order of severity thereof of dispersive electrode contingent when using electric knife; Simultaneously can also obviously reduce the trouble that the normally used electric knife ubiquity edge of a knife or jaw fragment of tissue adhere to, make it the situation that fragment of tissue adheres to blade seldom to occur when one pole work about electric power pattern, fragment of tissue is attached to the also corresponding minimizing of chance of jaw during bipolar operation; Self adaptation indicator 4 is in order to the normal operating conditions of indication Adaptable System, and the effect that bright expression TURP of lamp or electricity coagulate is finished, and electric knife can cut or carry out new electricity forward and coagulate; Short circuit monitoring protection instrument 5 is in order to the unlikely damage of protection instrument automatically in time; Leakage current monitoring and protection instrument 6 is in order to guarantee that patient is not injured by the power frequency leakage current.
Each several part of the present invention is to connect by accompanying drawing 3; its main part is an adaptive control system; it is to import signal into the otch state identifier by high frequency power generator; repeated transmission is gone into adaptive controller; be fed back into the unidirectional closed loop system of high frequency power generator again through logical process; adaptive controller can represent that high frequency power generator is equipped with short circuit monitoring protection instrument and leakage current monitoring and protection instrument by the self adaptation indicator, can guarantee the security reliability of instrument.
Device of the present invention is behind energized and power output switch, and electric knife is in the only SBR of exportable smaller power automatically, and this moment, the self adaptation display lamp was bright; When beginning cutting and having current increases to occur, electric knife is converted to high-power output automatically and continues and keeps, and this moment, the self adaptation display lamp extinguished automatically; And it is dry to bleach to incision tissue, and system is adapted to optimum state apace, and this moment, the self adaptation display lamp was shinny again, and the indication patient can carry out next step operation.
Characteristics of the present invention are: user need not to have in advance and uses electric knife and select appropriate TURP or electricity to coagulate the experience of power according to edge of a knife state, and do not worry in using the high frequency electric knife process, occurring the danger of incision tissue's burn, can prevent also that simultaneously contact surface reduces dispersive electrode, the local burning accident that causes that increases of electric current density because of accidental cause makes.In addition, do not having fragment of tissue substantially and adhering in order to carry out this TURP or the edge of a knife that coagulates of electricity or jaw, thereby can greatly reduce the trouble that often needs to eliminate the edge of a knife or jaw attachment in the art.
