Abstract
The utility model provides a spiral pushing type extradural puncture needle which is composed of an inner trocar, a push needle, a nut and a puncture guiding needle. The push needle is provided with an external thread matched with the nut. The puncture guiding needle is provided with a needle body, a blocking plate and a guiding needle head. Because the utility model has the advantages of simple structure, convenient operation and easy control, an anaesthetist or a surgeon can accurately carry out puncture on a neck, a chest and the epidural space of a lumbar vertebra. So the pain of a patient is mitigated, and the possibility of complications which are caused is reduced. The utility model is an extradural puncture needle which is worth being popularized at present.
Description
This utility model belongs to medical apparatus and instruments, the improvement of particularly medical anesthesia anesthesia spinal needle.
At present, the operating technology of traditional cavum epidural puncture pin (being the TUOHYShi pin) is had relatively high expectations, and one of difficult point of piercing process is how steadily, accurately and effectively: thrust epidural space, and do not make the needle point mistake wear spinal dura mater and spinal cord.But grasp this point, for young anesthesia doctor and spinal surgery doctor is difficult, because in case grasp improperly, will cause: 1, spinal dura mater punctures, as find in time can stop injection, but anesthesia and operative treatment have been incured loss through delay, if the end discovery can cause medicine to inject subarachnoid space, the lighter's respiration inhibition, sudden cardiac arrest can appear in weight person.2, stab spinal cord, the partial paralysis of limbs can occur.3, in a single day puncture dura mater,, can leak outside, intracranial hypotension headache, dizziness occur because of cerebrospinal fluid because puncture needle is thicker.
The purpose of this utility model provides a kind of epidural puncture, accurate, complication and the danger of having avoided traditional epidural needle puncture to cause, make that puncture is accurate, steady, safe and reliable, more convenient to operate, grasp easily and economical and practical screw-pushing type anesthesia spinal needle.
The purpose of this utility model is achieved in that it is by interior trocar 1, push pin 2, nut 3 and puncture guide pin 5 are formed, interior trocar 1 is located at pushes pin in 2,2 the postmedian of pushing pin is provided with external screw thread 3, nut 4 is sleeved on external screw thread 3 places of 2 postmedians of pushing pin, puncture guide pin 5 is sleeved on 2 anterior outer screw threads, 3 places of pushing pin, and external screw thread 3 is passed through, puncture guide pin 5 is by needle body 6, baffle plate 7 and guiding syringe needle 8 are formed, one end of needle body 6 is provided with all ring recess 12, baffle plate 7 is located between needle body 6 and the guiding syringe needle 8, on baffle plate 7, be provided with 4 circular holes 10, be provided with shoulder hole 11 in the puncture guide pin 5, plate washer 7 can be an one with the needle body 6 of puncture guiding needle 5, also can be as two bodies.
Accompanying drawing is a structural representation of the present utility model, also is a best at present embodiment of this utility model.
When using this utility model, but but also lateral position of patient's seat, after the doctor determined entry point, the local skin infiltration anesthesia according to the difference of site of puncture, was determined needle angle, at first thrust puncture guide pin 5, with the strain of restriction skin.Again the suit all-in-one-piece is advanced pin 2 and interior trocar 1, thrust in the lump in the puncture guide pin 5, thrust certain depth, trocar 1 in extracting out, connect syringe on 2 the backshank 13 of pushing pin, the right hand is held syringe and is steadily pushed away thorn forward, left hand rotating nut 4, make and push pin 2 slowly to the epidural space propelling, notice that simultaneously observing syringe has or not negative pressure appearance, the affirmation spiral pushes pin 2 at epidural space, to epidural injection, extraction pushes pin 2 and puncture guide pin 5, and the needle point wound is wrapped up with sterile gauze, and whole piercing process finishes.
This utility model is because grasp simple in structure, easy to operate, easy can make anaesthetist or surgeon can carry out like clockwork when cervical vertebra, thoracic vertebra and lumbar vertebra cavum epidural puncture, thereby alleviated patient's misery, also having reduced the probability that leads to complications, is the anesthesia spinal needle that is worthy to be popularized at present.
