Auxiliary method for epidural anesthesia needle placing

Abstract

The invention relates to an auxiliary method for epidural anesthesia needle placing, and a device applied to epidural anesthesia needle placing. The device comprises a needle placing unit, a movementguiding unit and a control unit, wherein the movement guiding unit is used for driving the needle placing unit to move; the control unit is used for supporting and controlling the movement guiding unit; and the needle placing unit is mutually and electrically connected with the control unit. The auxiliary method comprises the following steps: S1, an objective point position of an objective regionis obtained, and the control unit controls the movement guiding unit to guide the needle placing unit to the objective point position; S2, the needle placing unit is driven to propel in a puncturing direction, the control unit receives an electrical signal fed back by the needle placing unit and judges whether a needle stopping signal is triggered or not according to the electrical signal, and ifyes, the control unit stops driving the needle placing unit; and S3, a puncturing result of the needle placing unit is judged, and a judged result is outputted. The auxiliary method disclosed by the invention is diversified in monitoring means, and scientific and reliable detection is performed on the puncturing process and the determination after puncturing, so that the possibility of erroneous judgment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an auxiliary method for needle placement for epidural anesthesia. Background technique [0002] Epidural anesthesia has been used clinically for more than 90 years, and has been gradually improved through continuous practice and research, and has become a commonly used method in clinical anesthesia. Compared with general anesthesia, the incidence of pulmonary embolism, deep vein thrombosis, pneumonia, myocardial infarction, wound infection and respiratory depression caused by epidural anesthesia is lower, the impact on various organs of the body is small, and the economy is better. However, at present, clinical epidural anesthesia still uses blind exploration and manual operation. Doctors rely on subjective perception to identify the epidural space, which makes the positioning of the puncture needle and catheter uncertain, resulting in poor controllability of anesthes...
