Description
Technical field
The present invention relates to medical apparatus and instruments leader, relate more specifically to a kind of puncture needle for nerve block.
Background technology
Nowadays, peripheral nerve block has been the anaesthesia technology of a comparative maturity, and it is by nerve and the neighbouring local anaesthetics injecting doses of teleneuron reach anaesthetic effect around.Meanwhile, it is a frequent part as Combinated easing pain technology also, often and other analgesics and analgesia method use in conjunction control the pain of patient.
Peripheral nerve block is anaesthetized with other and is had significant advantage compared with analgesia method.First, peripheral nerve block is only anaesthetized specific operative region and does not almost affect other tissue systems of health, and patient tolerance is good.Secondly, traditional anesthesia analgesia pharmaceutical requirements amount is large, and usually brings nauseating, vomiting and respiration inhibition etc.Peripheral nerve block then there will not be above-mentioned symptom.And the patient accepting peripheral nerve block has higher satisfaction compared with other anesthesia or analgesia method.
But find in clinical practice: no matter be anesthesia or analgesia method, most of clinicist all not using peripheral nerve block as first-selection.Chief reason is that current puncture needle for nerve block can only in most advanced and sophisticated injection, to the puncture of needle point end to put forth effort status requirement very high, need point-device puncture to put in place, could accurately by injecting liquid drug to waiting to anaesthetize neural position, add venipuncture difficulty and puncture time; In addition, existing nerve block is threaded a needle and is single hole fluid, and slowly, anaesthetic effect is not good for the expansion of single hole fluid.And puncture needle for nerve block used is at present draw point material, because its tip is sharp keen, not only easy when puncturing damaged nerve tissue and blood vessel, and be not easy to be retained in patient body, Postoperative Analgesia After therefore cannot be provided to treat and sustained drug treatment.
Therefore, be necessary to provide a kind of puncture needle for nerve block of improvement to overcome above-mentioned defect.
