Micromirror spinal dura mater external cavity puncturing device

Abstract

The invention discloses a micromirror spinal dura mater external cavity puncturing device, which mainly comprises a puncture needle medicine outlet, a micromirror camera, a water injection port, a thrust sensor, a water storage bag, a water injection pipe, an optic guide fiber, a syringe body, an electric control push rod, a connecting line and a micromirror computer, wherein the puncture needle medicine outlet is arranged under the water injection port, the micromirror camera is arranged in front of the puncture needle medicine outlet, the water injection port is arranged behind the micromirror camera, the thrust sensor is arranged in front of the electric control push rod, the electric control push rod is arranged under the connecting line, and the micromirror computer is arranged between the thrust sensor and the electric control push rod. The device has the advantages that the accurate puncturing process of the electric control push rod is ensured, and the accuracy of the puncturing position is improved; the manual operation is replaced by the micromirror camera, the judging accuracy is high, and the puncturing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of epidural puncture, and in particular relates to a spinal epidural puncture device under a microscopic microscope. Background technique [0002] During the epidural puncture operation, how to determine whether the puncture needle has reached the epidural space is a very critical issue. Only when the puncture needle is accurately positioned in the epidural space can the catheter be placed and the drug administered. Drugs can easily cause anesthesia failure or even surgical failure and death. In the prior art, doctors mostly rely on experience and hand feeling to judge whether the puncture needle enters the epidural space. When using it, it depends entirely on the doctor's hand feeling, which is not intuitive. When the needle punctures into the subcutaneous tissue and reaches the dense ligament tissue, the needle is blocked and the pressure is high. When the needle is punctured into the epidural space, the ...
