Lumbar puncture teaching model for visualizing puncture points

Abstract

The invention discloses a lumbar puncture teaching model for visualizing puncture points. The model comprises a simulation human body, a simulation lumbar vertebra module and a simulation pelvis module; the simulation lumbar vertebra module and the simulation pelvis module are connected and embedded into a simulation human body; the simulation lumbar vertebra module is at least provided with a simulation supraspinous ligament, a simulation interspinous ligament, a simulation ligamenta flava, a simulation hard spine module, a simulation vertebral canal, simulation cerebrospinal fluid, a fourthsimulation lumbar vertebra bone and a fifth simulation lumbar vertebra bone, wherein the fourth simulation lumbar vertebra bone and the fifth simulation lumbar vertebra bone are adjacently arranged; alumbar puncture marking ring right facing the intervertebral space between the fourth simulation lumbar vertebra bone and the fifth simulation lumbar vertebra bone is arranged on the symmetrical center line of the back of the simulation human body; the simulation human body comprises simulation skin and simulation subcutaneous muscle tissues; a view window is formed in the right waist of the simulation human body; a perspective soft rubber block which can be perspective to the simulated subcutaneous muscle tissue and the simulated lumbar vertebra module is embedded in the view window. The model has the advantages that lumbar puncture points are visualized, a puncture path is visualized, the practicability is high, and the lumbar puncture technical level of a practitioner can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical teaching tools, in particular to a lumbar puncture teaching model which visualizes puncture points. Background technique [0002] The indications for lumbar puncture mainly include: ① Checking the properties of cerebrospinal fluid to assist in the diagnosis of central nervous system inflammation or hemorrhagic diseases; ② Measuring intracranial pressure and knowing whether the subarachnoid space is blocked; ③ Other auxiliary examinations, Such as pneumoencephalography, spinal air angiography, radionuclide scanning of ventricle and brain cisterns, etc.; ④, for intracranial hemorrhage, inflammation or after craniocerebral surgery, drainage of irritating cerebrospinal fluid can relieve clinical symptoms; ⑤, perform lumbar anesthesia or intrathecal Injection medication. [0003] In the prior art, before performing a lumbar puncture on a patient, doctors generally need to use a lumbar puncture model t...

Problems solved by technology

[0006] Specifically, on the one hand, identifying the puncture point is the first step in lumbar puncture practice. When the puncture point is not identified, the puncture practice through the wrong puncture point is a waste of effort, that is, the existing lumbar puncture model It is not possible to intuitively give guidance on the correct position of the puncture point for reference by the practicing doctor, so that the practicing doctor cannot make every lumbar puncture practice effective; on the other hand, the existing lumbar puncture models only have simulated human body The torso and the simulated lumbar spine embedded in the corresponding simulated human torso do not fully simulate the structure of the human body, that is, they do not show the hierarchical structure of the various tissues of the human body from the outer skin to the innermost lumbar spinal canal, so that practitioners cannot fully understand what it is. What is the puncture path of the puncture needle used in the practice, which leads to the existence of blind spots in knowledge, and the puncture practice is carried out according to the selected puncture point and puncture direction without knowing why. When the puncture is blocked, because they do not know the specific hierarchical structure of the human body, they cannot effectively and quickly make on-the-spot puncture corrections according to the specific hierarchical structure of the human body, and the practicing doctor uses the existing corresponding lumbar puncture model to perform puncture exercises based on feeling , can not be visualized, making it inconvenient for them to observe whether the puncture path is correct during lumbar puncture practice, making it impossible to effectively improve their technical level of lumbar puncture practice

[0007] Therefore, the structure of the existing lumbar puncture model needs to be improved and optimized
