Description
Technical field
This utility model belongs to medical apparatus and instruments and therapeutic field of tumor.Relate to a kind of novel medicinal intelligent electrosurgical, be specifically related to a kind of high-frequency surgery electric knife with optical fiber probe, this utility model is on the basis of original high-frequency surgery electric knife, add the design of Raman fiber probe, obtained a kind of can passing through detects the difference Intelligent Recognition tumor tissues of Raman spectrum and the medical operation electric knife of normal structure in real time.In this intelligent operation electric knife energy art of the present utility model, quick diagnosis is good pernicious.
Background technology
Operation is one of primary treatments of current malignant tumor, its with scalpel, cut, operation that the apparatus such as pin carries out at body local, remove the tumor tissues of pathological changes, repair damage and carry out treating disease.High-frequency surgery electric knife is applied to the history of clinical existing more than 90 year so far from nineteen twenty.--the more change in high power valve--high power transistor--high-power MOS tube four generation that experienced by spark-discharge therebetween; Along with universal, application, the development of computer technology, implement the automatic adjustment to power waveform, voltage, electric current under various function, the detection of various safety index, and the detection of Programmed control and fault and instruction, thus substantially increase the safety and reliability of equipment itself, simplify the operating process of doctor.
The high-frequency surgery electric knife of current Clinical practice is primarily of main frame and electrotome handle, electrode and patient's pole plate and foot switch adnexa composition.Doctor uses scalpel can excise the tumor tissues etc. of pathological changes clinically, but in lumpectomy procedure, surgeon cuts in order to avoid tumor tissues leaks, and general method is enough apart from so-called normal structure tumor resection from borderline tumor.But in clinical practice, due to the difference of tumor location, be difficult to accomplish to keep negative cutting edges to balance with preservation organ dysfunction, simultaneously, by means of experience and the perusal of doctor, be difficult to the boundary precisely distinguishing tumor tissues and normal structure, once there is positive margin residual tumor, bring a very large difficult problem by for follow-up treatment, also can have influence on the prognosis of patient.But current electrosurgical does not all possess the function of Real time identification tumor.
Since the nineties in last century, along with the development of laser technology and the application of new detector technology ripe gradually, the application of Raman spectroscopy is more and more extensive; Because human organ tissue comprises tumor tissues with regard to its basic chemical composition, be all by protein, nucleic acid, the biomolecule such as lipid and saccharide forms.The molecule of different structure has different Raman spectral characteristics, thus can identify from the Raman signatures spectrum of material and distinguish different materials.According to the difference in the composition of composition each in tumor tissues and normal structure and molecular conformation, make the difference of being caught raman scattering spectrum by clinical fiber Raman spectral technique, directly with Real time identification malignant tumor and normal structure become possibility in vivo.Studies have found that and genetic algorithm is applied in Raman spectrum analysis, live body can be done to early stage cancerous tissue and identify fast; Have raman bands that research display analysis identification cervical cancer tissues obtains to cancer early diagnosis accuracy 82.9%(sensitivity 72.5% (29/40), specificity 89.2% (58/65)) ".Fiber Raman spectrum can provide the molecular structure information of tissue samples as a kind of optical technology.P.Crow etc. analyze 220 Raman spectrums of 29 routine freezing bladder cancer samples, and result shows that Fiber optic near infrared spectroscopy Raman spectrum can be used for the in-vitro diagnosis of transitional cell carcinoma of bladder.
In view of the defect that prior art exists, present inventor intend providing a kind of can improve thorough excision cancerous issue as much as possible and preserve a kind of of the precision of more normal structures can the method for Real time identification cancerous issue and normal structure and instrument.
