Embodiment approach

[0051] Such as figure 1 As shown, according to one embodiment of the present invention, an auxiliary method for needle placement in epidural anesthesia of the present invention is applied to a device for needle placement in epidural anesthesia, and the auxiliary method includes:

[0052] S1. Acquiring the target point of the target area, the control unit 3 controls the guiding motion unit 2 to guide the needle setting unit 1 to the target point;

[0053] S2. Drive the needle setting unit 1 to advance along the puncture direction, the control unit 3 receives the electrical signal fed back by the needle setting unit 1, and judges whether the needle stop signal is triggered according to the electrical signal, and if so, stops driving the needle setting unit 1;

[0054] S3. Evaluate the puncture result of the needle placement unit 1, and output the judgment result.

[0055] In order to further illustrate the present invention, firstly, the device of the present invention will be ...

Abstract

The invention relates to an auxiliary method for needle placement in epidural anesthesia, which is applied to a needle placement device for epidural anesthesia, and the device includes: a needle placement unit, which is used to drive the guide movement of the needle placement unit to move unit, and a control unit for supporting and controlling the guiding movement unit, the needle setting unit and the control unit are electrically connected to each other; the auxiliary method includes: S1. Obtain the target point of the target area, and the control unit controls the guiding movement The unit guides the needle setting unit to the target point; S2. Drives the needle setting unit to advance along the puncture direction, and the control unit receives the electrical signal fed back by the needle setting unit, and judges whether to trigger the needle stop signal according to the electrical signal, if so , stop driving the needle placement unit; S3. judge the puncture result of the needle placement unit, and output the judgment result. The monitoring means of the present invention are diversified, scientific and reliable detection is carried out on both the puncture process and the judgment after the puncture, and the possibility of misjudgment 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...
