Description
Technical field
The invention belongs to medical assistive device technical field, relate to the clinical harvester of Fine-needle Aspiration Cytology, especially Cell collection device.
Background technology
Fine-needle Aspiration Cytology (fineneedleaspirationcytology, abbreviation FNAC) be utilize the compositions such as the cell in fine needle aspiration absorption lesions position to make smear, observe a kind of biopsy diagnosis that its tumor and non-tumor cell morphologic change and interstitial change.In implementation process, according to tumor quality and character thereof, the capable paracentesis of the disposable syringe of about 10cm specification can be adopted respectively at present.By patient's body surface, draw palp lump pathological changes, or by guiding such as x-ray, B ultrasonic, CT and radioisotope scannings, pin suction is carried out to deep organ disease, draw microtissue composition and (comprising cell, interstitial or other accompaniments) carry out Cytomorphology, a series of relevant cells that also can carry out living cells learn a skill research.
The method of Fine-needle Aspiration Tissues is easy, safe, fast, sensitivity is good, and diagnosis rate is high, and credibility is strong, and is close to non-invasive to patient, one of important diagnostic method now becoming clinical disease.
The maximum superiority of cytodiagnosis is can with morphologic basis early discovery and diagnosing tumour, its operation and diagnostic method is easy, safe, directly perceived, any other preoperative planning current hardly matches, and needle absorbing mainly contains following advantage:
1. generally do not need special installation, be easy to carry out at medical department at different levels.
2. fine needle aspiration is close to body not damaged, and cicatrix is not left in local, and hemorrhage infection chance is very few, and patient's misery is little, is easy to be accepted by patient.To Deep Lesions and nerve, euangiotic critical position, FNAC has better safety and feasibility.
3. smear cells is fresh, not easily produces degeneration and autolysis; Cell not easily occurs artificially to extrude equivalent damage, and morphosis is clear, is conducive to the accurate identification under mirror and Differential Diagnosis.Diagnosis for more typical cytology's case is quick, usual its diagnostic result of patient's immediate delivery.
4. for some once negative or suspicious diagnosis, immediately can repeat to draw materials with multiple location inspection, and be convenient to examining, dynamically observing and observation of curative effect.
5. the good pernicious diagnosis rate of pair pathological changes is high.Having can up to more than 95% compared with the usual diagnosis rate of clinical cytology diagnostician of rich experiences, and lesion type diagnosis rate can reach more than 80%.
6. applied range, is almost applicable to any site morbidity of body.Under being guided by imaging localization such as x-ray, B ultrasonic, CT and MRI, Puncture cytology diagnosis can be carried out to each deep organ's tissue of health.
7. aspirate is living tissue, can be used for the inspections such as other biological experiment, cell culture, immunology and molecular biology.
8. complement one another with the diagnostic method such as histopathologic examination.
9. some pathological changes is as galactocele, retention cyst of salivary gland etc., and puncture can reach therapeutical effect.
Great mass of data shows, although FNAC has many advantages, still have minority case to occur mistaken diagnosis, usual false negative is greater than false positive.Whether proper the draw materials diagnostic level etc. of satisfaction, film-making and cytology worker of main cause and pathological changes be closely related.
Due to the tissue mass of fine needle aspiration and cell component less, the tissue morphology in specimen and intercellular substance structure major part or completely lose, thus can not reflect the overall picture of lesion type; To specific diagnosis and the analysis of cancer growth tissue, judge that the tissue-derived case had of metastasis remains limitation.
Clinical cytology is a kind of diagnostic but not screening property technology, the advantage having it valuable and some limitation part.In order to improve the accuracy rate of cytodiagnosis, the link of three aspects must be got hold of: 1. perfect and puncture technique and have the acquisition of diagnostic value cytologic specimen accurately; 2. the smear of high-quality and Color; 3. close combination with clinical data carries out the accurate analysis to smear.Meanwhile, not only emphasize that clinicist is to the interest of clinical cytology and confidence, more will pay attention to its knowledge renewal of cytodiagnosis person, diagnostic experiences of enriching constantly.
How current research and development institution both domestic and external improves the ability of syringe needle adherent cell mostly in research, if but lack necessary vacuum suction, then for puncture suction tuberosity, harder and lack the tuberosity of blood confession, its cell is difficult to effectively be adsorbed all the time, cannot improve diagnosis rate.Unfortunately, there is no the difficulty that the suitable collecting device with vacuum suction function can reduce one man operation.
The method of Fine-needle Aspiration Tissues is easy, safe, fast, sensitivity is good, and diagnosis rate is high, and credibility is strong, and is close to non-invasive to patient, and one of important diagnostic method now becoming clinical disease, potential applicability in clinical practice is wide.But also have some limitations simultaneously.In above-mentioned limitation, pathological changes satisfaction of drawing materials is closely bound up with clinicist.If clinicist can realize perfect and puncture technique and have the acquisition of diagnostic value cytologic specimen accurately in operation, so the limitation of Fine-needle Aspiration Tissues will be more and more less, and potential applicability in clinical practice will be more wide.And want to improve in this respect, then must from operation itself be said.
In the operating process of Fine-needle Aspiration Cytology, patient's right hand is held pin and is punctured into tuberosity through skin rapidly, when needle point puncture is to swollen thing centre, there are two kinds of modes of operation at present: one, when two people operate, assistant is auxiliary retracts pintle, causes about 3 ~ 4ml negative pressure.Puncture person extracts puncture needle after puncture needle is repeatedly aspirated 5 ~ 10 times in tuberosity.Two, during one man operation, namely patient will retract pintle, causes about 3 ~ 4ml negative pressure, after again puncture needle repeatedly being aspirated 5 ~ 10 times in tuberosity, extracts puncture needle.The advantage of two people's operations is that patient only need carry out puncture needle in tuberosity, repeatedly aspirate the accurate operation of 5 ~ 10 times, and cause the extensive operation of about 3 ~ 4ml negative pressure to give assistant to complete by retracting pintle, thus make patient avoid carrying out self-contradictory action on hand same, reduce the generation of various danger, be conducive to concentrating one's energy to carry out accurate aspiration biopsy to target.Shortcoming is that two people's operations require high to the cooperation of patient and assistant, if both sides lack accurate synchronicity, the probability that various danger so occurs can significantly raise on the contrary, and therefore two people's operations have feasibility, but are unfavorable for carrying out on a large scale of technique.The advantage of one man operation is that patient coordinates without the need to other people, and operation has high synchronicity, is conducive to realizing perfect and puncture technique and have the acquisition of diagnostic value cytologic specimen accurately, farthest avoids the generation of various danger.Shortcoming is that patient should complete the extensive action retracting pintle generation negative pressure on the other hand, complete again and puncture needle is repeatedly aspirated fine movement for several times in tuberosity, thisly inherently belong to self-contradictory action, require that patient has extremely strong body harmony, and most of clinicist is obviously difficult to skilled grasp, this just easily causes various danger to occur, and reduces success rate and the accuracy rate of aspiration biopsy.Therefore one man operation is conducive to realizing perfect and puncture technique and have the acquisition of diagnostic value cytologic specimen accurately most, at utmost avoid the operational approach that various danger occurs, but with regard to current equipment, be only applicable to the clinicist that body harmony is extremely strong, because most of clinicist is difficult to skillfully master a skill main points, be therefore difficult to benefit masses.Research and development are objectively needed to be suitable for one man operation's cellular collector.
