Abstract

The invention provides an epidural puncture needle preventing an epidural catheter from being cut off, and the epidural puncture needle can prevent the catheter from being cut off in an intraspinal anesthesia operation. The epidural puncture needle preventing the epidural catheter from being cut off aims to overcome the defect that the epidural catheter is prone to being cut off by an existing epidural puncture needle, and the epidural catheter is not cut by the end face at the opening position of a needle tube. The epidural puncture needle comprises a needle seat and a needle body, the needle body is of a tubular structure, and the head of the needle body is a spoon-shaped needle point used for puncturing; the tail of the needle body is fixed to the needle seat; the open position of the inner wall of the needle point is of an obtuse structure and cannot cut the epidural catheter when making contact with the epidural catheter. Compared with an existing epidural puncture needle, the epidural puncture needle has the advantages that the epidural catheter is prevented from being cut off, and the epidural puncture needle is safe and convenient to use for puncturing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an epidural puncture needle for preventing epidural catheters from being cut off during intraspinal anesthesia operations. Background technique [0002] At present, in clinical anesthesia and pain treatment, continuous epidural block anesthesia, epidural analgesia, and continuous epidural drug administration are still widely used. During the operation, the anesthesiologist first punctures with the epidural puncture needle, and punctures the spoon-shaped mouth of the needle tip into the epidural space or other target sites, such as the myofascial space; and then punctures the epidural catheter from the epidural Insert the tail of the needle, pass through the hollow needle body, and then pass through the spoon-shaped opening of the needle tip of the puncture needle, and insert an appropriate length according to the needs; after confirming that the epidural catheter is not i...
