Minimally invasive anesthesia needle

Abstract

The invention discloses a minimally invasive anesthesia needle, which comprises a needle base and a needle tube arranged on the upper end of the needle base, a minimally invasive anesthesia device is arranged on the upper end of the needle tube, and the minimally invasive anesthesia device is a cavity structure, the The cavity structure is in communication with the internal cavity of the needle tube. The minimally invasive anesthesia device includes a flat cylinder cavity and an anesthesia needle point matrix, and the anesthesia needle point matrix is ​​arranged at the center of the upper end surface of the flat cylinder cavity. And it accounts for about half of the upper surface area of ​​the oblate cylinder cavity. Its design is reasonable, the injection depth is easy to control, the anesthesia speed is fast, the anesthesia effect is good, and the pain and discomfort caused by local infiltration anesthesia can be minimized.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to a needle, in particular to a minimally invasive anesthesia needle. Background technique [0002] Anesthesia temporarily deprives the patient of the whole or part of the sensation through drugs or other methods, so as to achieve the purpose of painlessness, and provides conditions for surgical treatment or other medical examination and treatment, so as to avoid mental stress and reflex adverse reactions of the patient, thereby increasing the discomfort of the patient And pain, so that patients can undergo surgery or diagnostic medical examinations in a comfortable and quiet environment without responding to adverse stimuli and temporarily losing memory, so that patients can recover as soon as possible. [0003] Anesthesia is generally divided into three types: general anesthesia, local anesthesia, and combined anesthesia. Local anesthesia refers to the use of local anesthetics to tem...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no special injection equipment when injecting local anesthetics in local infiltration anesthesia. Generally, the common syringes on the market are still used, and the injection depth is not easy to control. We can only rely on medical staff to inject local anesthetics into the surgical site based on personal experience. Then wait for the anesthetic to slowly spread to all layers of tissue in the entire operation area. The waiting time is long, and the injection needle is large, which is easy to cause pain and discomfort.
