Technical Field
The invention relates to the technical field of medical equipment, in particular to an anesthesia device for a pain department.
Background
Pain has been listed by modern medicine as the fifth vital sign following respiration, pulse, blood pressure, body temperature. Some chronic pain itself is also a disease (e.g. trigeminal neuralgia, postherpetic neuralgia, etc.). Chronic local pain can form complex local pain syndrome or central pain, so that common pain becomes very severe and difficult to treat, various complications are induced by dysfunction and reduced immunity of all systems of the body, and even the patients are disabled or endangered in life. In the treatment of pain, anesthesia is one of the commonly used treatments.
In the prior art, an anesthesia puncture needle is needed for clinical anesthesia puncture, and the existing anesthesia puncture needle has no guide device or no power assisting device, so that medical personnel can master the direction and the force completely. Because the puncture needle is small, when a hard tissue part is punctured or obliquely punctured, a proper angle is difficult to master, the puncture wound is large, and the patient is easy to suffer. However, in practice, the puncturing hand feeling is a rather unclear concept, is related to the experience of the operator and the constitution of the patient, cannot be used as a normal operation guide, and even the experienced operator cannot avoid the accident of puncturing the inner cortex to damage the spinal cord or nerve roots.
