Embodiment Construction

[0026] The non-injury epidural catheter puncture needle includes a needle tube 1 for placing an anesthesia catheter 7, a needle seat 2 connected to the tail end of the needle tube, and a needle blade 4. The inner cavity of the needle holder 2 is a tapered hole structure, the front part of the needle holder is provided with a card slot, and the needle tube is made of medical stainless steel.

[0027] The needle blade is arranged obliquely at the head of the needle tube. The head of the needle tube 1 is an arc-shaped structure 6 extending upward, and the needle blade 4 is arranged at the end of the arc-shaped structure. This structure can facilitate the anesthesia catheter to find the corresponding needle application site for anesthesia.

[0028] The inner cavity of the needle tube is provided with a FEP protective sheath 3, and the protective sheath is placed between the anesthesia catheter and the needle tube. The protective sleeve 3 is cemented and connected to the inner wall...

Abstract

The invention relates to a non-destructive epidural outer catheter puncture needle and belongs to the technical field of medical devices. The non-destructive epidural outer catheter puncture needle comprises a needle tube for allowing an anesthesia catheter to be placed in, a needle seat connected with the tail end of the needle tube and a needle blade, wherein the needle blade is obliquely arranged at the head of the needle tube. The non-destructive epidural outer catheter puncture needle is characterized in that a protective sleeve is arranged in an inner cavity of the needle tube; a guide tongue is arranged at the head of the needle tube and also arranged on a tube wall, opposite to the position of the needle blade, of the needle tube. The non-destructive epidural outer catheter puncture needle is simple in structure and obvious in technical characteristics and solves the problem that the needle blade cuts off the catheter in the tube conventional process after catheter anesthesia. According to the non-destructive epidural outer catheter puncture needle, the angle of the anesthesia catheter can be adjusted, the product operation is simple and convenient, the product safety is improved, and the secondary damage caused by the occurrence of clinical accidents to patients is prevented.

Description

technical field [0001] The patent of the present invention relates to a puncture device used in epidural anesthesia, in particular to a non-damaging epidural catheter puncture needle, which is used to puncture the human epidural when various epidural anesthesia operations are performed in hospital clinical institutions and injection medicine, belonging to the technical field of medical equipment. Background technique [0002] The epidural puncture needle widely used in the market at present, in the process of use, medical staff often encounters the phenomenon that the needle blade cuts off the catheter when withdrawing from the anesthesia catheter. After the anesthesia catheter is disconnected, it will remain in the patient's body. Usually, a second operation will be performed to remove it. For this reason, cause very big physical pain to patient, also increased the risk of operation. Contents of the invention [0003] The object of the present invention is to provide a ...
