Background

Puncture, a commonly used medical operating term, is a diagnostic technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, gas or contrast agents are injected into the body cavity to perform contrast examination, or medicines are injected into the body cavity. The purpose of puncture is to take blood for examination, blood transfusion, fluid infusion and to put in a catheter for angiography. Ventricular puncture can be divided into anterior horn puncture, lateral horn puncture and posterior horn puncture. The skull is quickly drilled through 2 cm behind the anterior hairline and 2.5 cm beside the midline by using a skull awl, and then a lumbar puncture needle or a ventricular drainage tube is used for puncturing the anterior horn of the lateral ventricle. When the cerebral hypertension is too high, the patient is coma, the pupil is enlarged, the respiratory surface is shallow, and the cerebral hernia is formed, the rapid ventricular puncture is carried out to release the ventricular fluid, and the cerebral hernia can be immediately relieved. The ventricular pressure can be measured, or a drainage bottle is connected to conduct ventricular continuous drainage, ventricular fluid is taken for assay, and methylene blue can be injected to know the circulation condition of cerebrospinal fluid. Air, oxygen and contrast agent can be injected from the puncture needle to diagnose intracranial space occupying lesion and ventricular system obstruction. Contrast should not be done for patients with iodine allergy. The ventricular fluid drains from the Shaanxi and occasionally causes epidural and subdural hematoma. The puncture guide is mainly used for guiding the puncture needle, however, the existing puncture guide is complex to use and is not beneficial to a doctor to use.
