Description
Technical Field
The invention belongs to the technical field of medical auxiliary equipment, and particularly relates to an abdomen image diagnosis positioning device.
Background
Ultrasound image guided abdominal puncture has been widely used as a non-invasive, non-radiative medical technique. The method and the device can be used for guiding accurate positioning of a body position region of interest (ROI) by using the technology and performing puncture sampling operation in the early screening and treatment process of abdominal cavity organ diseases such as liver, spleen, pancreas, kidney and the like of a patient by generating high-frequency sound waves in real time and transmitting the high-frequency sound waves into the patient, and converting returned echoes into images, thereby achieving the purpose of effective diagnosis. However, the diagnosis of abdominal puncture under the guidance of ultrasonic images still has the defects in specific application.
(1) In the operation process, one hand is needed to hold the ultrasonic probe and the other hand is needed to hold the puncture needle, so that a doctor can feel tired and weak when using one hand for operation for a long time, and the shake and instability of the hand can be caused. Due to the limitations of one-handed operation, the physician may not reach the required level of precision, possibly resulting in a puncture deviating from the target area. Meanwhile, a certain training and professional knowledge are required for the operation of single-hand puncture, and the threshold is high, so that the technology cannot be widely popularized and developed;
(2) The existing auxiliary positioning device for the abdomen ultrasonic image puncture has the problems of complex operation, low precision, poor practicability and the like, and cannot meet the requirements of modern medical diagnosis. For example, the puncture angle and the puncture length are determined through analysis by calculation processing, the method cannot be suitable for various scenes depending on the response time of the computing equipment, meanwhile, the calculated result is often a specific angle of a specific position, and once the puncture needs to penetrate through important protected organs at the position angle, the calculated result is invalid;
(3) In ultrasound guided penetration, it is classified into in-plane penetration and out-of-plane penetration. The out-of-plane puncture refers to the process that the puncture needle is entirely or locally punctured outside the sound beam emitted by the ultrasound under the guidance of the ultrasound, and a doctor cannot see the complete puncture needle, so that the position and the angle of the puncture needle to a target are difficult to grasp, repeated needle test is needed, and the requirements on the puncture technique and experience are very high. The existing puncture positioning auxiliary device based on the out-of-plane puncture method only considers the needle insertion point, does not accurately achieve the puncture angle, the puncture length and the like, and can cause the phenomenon of inaccurate puncture, once the puncture fails, the pain of a patient is increased, and the puncture complications are caused.
