Technical field
The present invention relates to a kind of operating theater instruments, particularly relate to a kind of intelligent organizational separating operation apparatus that can detect bio-electrical impedance, belong to the technical field of medical apparatus and instruments.
Background technology
Bio-electrical impedance detection technique is that a kind of electrical impedance characteristics of biological tissue and Changing Pattern thereof of utilizing extracts the detection technique to Human Physiology, biomedical information that pathological condition is relevant.This detection technique needs to apply faint alternating current or voltage signal by least two electrodes to detected tissue usually, thus according to applying curtage size and phase calculation complex impedance, finally obtain relevant physiology and pathological information according to different application targets.The advantage that bio-electrical impedance detection technique has noinvasive, reusable, cost is low, simple to operate and detection speed is fast.
In operation, doctor usually utilizes vision and tactile data and identifies tissue in conjunction with preoperative image data, completes blunt separation, sews up operation such as knotting grade.In actual operation, these information are not enough to make doctor accurately judge the position of important nerve and the blood vessel covered by its hetero-organization, and just impact is to blood vessel and neural lock out operation for this, and inaccurate point of defection causes malpractice.

Accompanying drawing explanation
Fig. 1 is the intelligent organizational separating operation apparatus schematic diagram that can detect bio-electrical impedance.
Fig. 2 is detecting electrode top view.
Fig. 3 is detecting electrode side view.
In figure, 1 detecting electrode, 2 connect wire, 3 electric impedance analyzers, 4 pedals, 5 rustless steel hemispheres, 6 glass mats, 7 Copper Foils, 8 electric connectors.
Detailed description of the invention
Operating theater instruments as shown in Figure 1, comprises detecting electrode 1, connects wire 2, electric impedance analyzer 3 and pedal 4.
Detecting electrode 1 as shown in Figures 2 and 3, its length is 200mm, by thickness be 1mm layer glass fibre board 6 in the middle of plating two width to be 1mm spacing be that 3mm thickness is 0.02mm and the Copper Foil 7 be parallel to each other forms (gap between fibre board is by adhesive of medical shutoff), the left end of detecting electrode is an inclined surface, for contacting tissue to be detected, right-hand member draws electric connector 8, connects electric impedance analyzer 3.
As shown in Figures 2 and 3, the inclined surface at detecting electrode 1 tip welds two rustless steel hemispheres, 5, two rustless steel hemispheres and be electrically connected with the Copper Foil of wherein respectively, hemisphere diameter 1.5mm, ball electroplating gold on surface, thickness is not less than 0.01mm.Two hemisphere centre of sphere distances equal the distance between two Copper Foils.The tip of detecting electrode 1 can ensure to carry out blunt separation operation to tissue while detection electrical impedance, and the leading edge at the most advanced and sophisticated position of inclined surface is circular arc simultaneously, and arc radius is 0.3mm, and this can ensure not damaged tissue.With welding hemispheroidal side contact need identification and the tissue be separated in operation, the impedance value according to gathering judges organization type, and then determines whether continue blunt separation operation.
Glass mat 6 physicochemical property in human body that detecting electrode 1 adopts is stablized, and has very strong corrosion resistance, can not discharge the anaphylaxis that heavy metal ion produces toxicity or causes human body.Gold is the best metal of biocompatibility, does not play any reaction with tissue.
Connecting wire 2 is Shielded Twisted Pair, and per share cross-sectional area is not less than 0.5mm2.
The frequency range that electric impedance analyzer 3 detects bio-electrical impedance is 200kHz-2MHz, and can be set by doctor, metrical error is not more than 1%.The sample frequency of impedance value is for being not less than 5Hz, and added current intensity is not higher than 1mA.Because this operating theater instruments is doctor's hand-held, inevitably there is physiological and tremble in the arm of people, so the impedance bioelectrical measurement value of display is the meansigma methods of data in 0.5 second.
The unlatching of impedance measurement function is controlled by pedal 4.After stepping on pedal 4, electric impedance analyzer 3 provides high frequency weak current by two hemispheres of electrode to tissue, reaches and measures the anti-object of tissue resistance.After unclamping pedal, electric impedance analyzer 3 quits work.
