Lumbar puncture needle used for injecting anesthetics and application method of lumbar puncture needle

Abstract

The invention discloses a lumbar puncture needle used for injecting anesthetics and an application method of the lumbar puncture needle. The lumbar puncture needle comprises an outer needle, an innerneedle structure and a second infusion tube and is characterized in that a first connector is connected to the rear end of the outer needle, the inner needle structure is provided with an inner needle, the inner needle can extend into the outer needle, the rear end of the inner needle is provided with a second connector, and the second connector can extend into a needle handle. The lumbar punctureneedle has the advantages that the lumbar puncture needle which is mainly provided with the outer needle, the inner needle structure and the second infusion tube is simple and reasonable in structureand convenient for medical application, the outer needle has certain firmness and cannot be easily broken during use, the body of the outer needle is provided with scale marks, the depth of the outerneedling puncturing into the waist of a patient can be displayed through the scale marks, the practical value of the needle is increased, and the surgery process can be facilitated; the inner needlestructure can extend into the outer needle structure to achieve easy and convenient injection, the pain of the patient can be relieved favorably, the iatrogenic infection chance of the patient can bereduced favorably, lumbar puncture time can be shortened, and lumbar puncture operation efficiency can be increased.

AI Technical Summary

Benefits of technology

This patented technology allows for easier insertion and removal of various types of instruments while maintaining their functionality. Its technical benefits include improved safety by reducing injury from sharp pointed tools that may cause bleeding at different points along its length, reduced blood loss due to accidentally cutting off excessive veins when inserting them, increased usability compared to existing devices without this features, enhanced precision, ease-of-use, and cost savings over current methods.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving lumber puncturing devices' ability to accurately control how much pressure they apply while being inserted through narrow spaces like spinal cord nerves (SCN). Current methods involve inserting thin needled syringe needles deeper than necessary without causing injury or disruptive bleeding. However, these techniques have limitations such as lack accuracy due to their rigidity, difficulty adjustable depth, potential harm caused by accidental insertion, increased risk from bloodstream contamination, etc., resulting in longer procedures times and higher costs associated thereto.
