Description

Ultrasonic intervention puncture device

Technical Field

The utility model relates to the field of medical equipment, specifically a puncture equipment is intervene to supersound.

Background

Puncture is a medical operation term, and is a diagnosis and treatment technology for puncturing a puncture needle into a body cavity to extract secretion for testing, injecting gas or contrast agent into the body cavity to perform contrast examination, or injecting medicine into the body cavity. The puncture aims at blood drawing test, blood transfusion, fluid infusion and angiography after being placed into a catheter. It is often used for infants. When bregma is not closed or the coronary suture is enlarged, a lumbar puncture needle is used to penetrate subdural fluid from the lateral angle of bregma or from the coronary suture, and subdural effusion is extracted when traumatic chronic subdural hematoma and purulent meningitis are treated, and then a proper amount of antibiotic is injected. The puncture needle 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 carotid artery or vertebral artery can be punctured, contrast agent is injected to carry out cerebrovascular angiography, and cerebral hemisphere blood vessels can be displayed by carotid artery angiography. The vertebraography can display the infravenous vessels. The puncture of the subarachnoid space of lumbar spinal cord by a lumbar puncture needle is an important clinical auxiliary examination method in the neurology department. Can be used for measuring the cerebral pressure, collecting hydrocephalus to carry out routine, biochemical and bacteriological examination and tumor cell and enzymological examination, and provides basis for diagnosing intracranial inflammation, tumor, hemorrhage and white matter demyelinating diseases. However, when the cranial pressure is too high, the lumbar puncture needs to be careful, preferably no liquid is discharged, and only cerebrospinal fluid in the connecting cerebral barometer hose is used for testing so as to avoid the occurrence of cerebral hernia. Contrast agents may also be injected into the subarachnoid space for down-going or up-going visualization. Air (or oxygen) can also be injected into the subarachnoid space and directionally flows into the cranium to perform intraspinal lesion radiography, ventricular pneumoencephalography and cerebral cistern radiography.

But traditional supersound intervenes puncture equipment is because simple structure, and the function is single, because the length of unable adjustment pjncture needle when carrying out the use device, it is not hard up and unstable even to appear in the puncture syringe needle when adjusting after, consequently for the patient bring the secondary damage, cause patient's suffocation even, seriously threaten patient's life safety, make also greatly reduced of staff's work efficiency simultaneously, because it is stable to need the long-time handheld of staff, consequently, bring the misery for the staff, increased the work degree of difficulty.
