Why is Insert Molding the Best Option for Your Spinal and Epidural Needles?

Many surgeries and procedures require the use of anesthesia so that the patient temporarily loses sensation. While more critical surgeries will typically use general anesthesia, which will cause the patient to lose consciousness, some surgeries may be better suited for a local anesthesia. Many times, the medical professional will pair this local anesthesia with some form of an epidural or spinal block so that the patient will not feel anything occurring in their pelvis, lower extremities, or lower abdomen.

The Difference Between an Epidural and Spinal Block

Commonly associated with birth, an epidural anesthesia is administered with a hollow needle and a small flexible catheter. The medical professional will insert these tools between the spinal cord’s outer membrane and the spinal column within the lower or middle back. Once in place, the local anesthesia is injected through the catheter, and the area will become numb.

Spinal Anesthesia, like an epidural, is administered with a needle in order to numb the patient’s lower extremities, however it differs from an epidural in that the injection goes straight into the cerebrospinal fluid, rather than into the actual spinal cord. This procedure usually calls for a much smaller needle, and does not typically require a catheter.

Why Insert Molding?

Though the two procedures are different in many ways, the quality of the devices used

should never be compromised. That is why it is important that you trust the company

behind your product. Many medical professionals and engineers are choosing insert

molding over older alternatives for a surplus of reasons.

  • Cost and Time Effective- other manufacturing options, such as heat staking and solvent bonding, require a significant amount of post-molding assembly with separate metal elements. Not only is this time consuming, but it can be financially costly as well. Insert molding eliminates this assembly saving both labor and resources.

  • Improved Quality- Precision mold tooling when paired with stringent process control ensures more accurate uniformity, reliability, and adherence to design of the product.

  • Stronger Materials- The insert molding process allows designers to integrate features into the plastic parts so that the parts may be stronger and more reliable than other plastic areas.

  • Allows Enhanced Product Design- Insert molding integrates features into the process that would not be possible using other methods.

  • Make Parts More Efficient- Not only is the process of insert molding more efficient, but it also allows for materials selection to be more varied. The process has opened up opportunities to create favorable plastic replacements of metal objects which allows the products to be less expensive, lighter, and less likely to corrode, all while maintaining the integrity and performance of the product.
