Description
Technical Field
The utility model relates to a clinical medical treatment technical field especially relates to a cross section puncture auxiliary assembly.
Background
In recent years, minimally invasive techniques have rapidly developed and become widespread, with a considerable part of the work being to perform deep tissue target punctures under CT. Ct (computed tomography), that is, electronic computed tomography, uses precisely collimated X-rays, etc. to scan sections of a human body one after another together with a detector with extremely high sensitivity, has the characteristics of fast scanning time, clear image, etc., and can be used for the examination of various diseases. The CT scanning requires that a human body lies down and enters the CT machine to scan the cross section of the human body layer by layer. Therefore, unlike the puncture under B-ultrasound or DSA (digital subtraction angiography), the puncture under CT cannot be performed under real-time dynamic observation, and needs to be performed step by step in the CT scanning plane, and often needs to be adjusted many times during the puncture process, which is time-consuming, long-lasting, and has a large error.
In the prior art, generally, medical staff puncture by hands completely, and after a body surface puncture point is defined, the angle and depth of a puncture needle are estimated by experience and gradually advanced, and the angle and depth are adjusted by repeatedly shooting a CT (computed tomography) in the advancing process of the puncture needle. With the improvement of the puncture precision requirement, the puncture needle is also positioned by a common protractor, and the positioning mode needs an auxiliary staff protractor to aim at the puncture needle to help medical staff to adjust the angle of the puncture needle on the cross section. In addition, the puncture needle is also provided with a plumb line and a protractor, an included angle is formed between the puncture needle and the plumb line after the puncture needle is inclined, and the angle of the puncture needle is adjusted according to the angle value displayed by the protractor. In addition, the laser device emits a laser beam according to a set angle, the laser beam indicates the needle entering position and the needle entering direction on the surface of the human body, and the medical staff inserts the needle along the indicating direction of the laser beam. However, the needle insertion process in the above manner is operated by hands of medical staff, the puncture precision depends heavily on experience and technology of the medical staff, and the error is large and the repeatability is poor.
Meanwhile, the needle insertion direction of the above-mentioned puncture method is usually limited to be performed in a single CT scanning plane, and the needle insertion plane is scanned for a plurality of times during the puncture process, which results in that cross-scanning tomography puncture cannot be performed based on CT images.
