A kind of Pain Management fixator for anaesthesia puncture
Technical field
The present invention relates to puncture fixator fields, are specifically related to a kind of Pain Management fixator for anaesthesia puncture.
Background technique
Puncture is will to puncture to be needled into body cavity and extract secretion to chemically examine, and injects gas or contrast agent to body cavity and does radiography
Check, or into body cavity injection of medicine a kind of diagnostic techniques, it is therefore an objective to blood test, blood transfusion, infusion and merging conduit do
Angiography can be divided into anterior horn puncture, side angle punctures and relief angle punctures three kinds, with cranium vertebra 2 centimetres after anterior hair line, by middle line
2.5 centimetres quickly drill through skull, then penetrate ventricular anterior horn with lumbar puncture needle or ventricular drainage tube, when brain hypertension, patient's dusk
Fan, hypopnea, when having hernia cerebri formation, carries out quick ventricular puncture and releases ventricular fluid mydriasis, and hernia cerebri can be alleviated immediately,
When anaesthetizing patient, when being punctured, need to use fixator for anaesthesia puncture.
Clinically when carrying out anesthetic puncture to patient, need to find anesthesia injection point, after being then inserted by certain angle
Injecting narcotic, but make operating difficulty since the movement of patient, injection point and injection angles can change in operating process
Increase, and in injection, due to there is no positioning device, needs to fix needle tubing manually, then press push-pull rod, operate so very
Trouble, and operating process Chinese medicine green hand once shakes, and is easy to increase the pain of patient, causes complication, although at present
Also some puncture fixators also can solve these problems, but to the injection angles for adjusting injection needle and when fixing injection needle, step
Suddenly it is all more troublesome, influences surgical procedure efficiency, increase risk.
