A Visual Ventricle and Subdural Epidural Drainage System

Abstract

The invention discloses a visible cerebral ventricle and subdural external drainage system. The visible cerebral ventricle and subdural external drainage system comprises a visible cerebral ventricle puncture system and a drainage system. The visible cerebral ventricle puncture system comprises a visible puncture guiding core, and LED light sources and a miniature camera are coaxially arranged at the intracranial end of the visible puncture guiding core. The wall of a puncture sheath is see-through, and millimeter scales are arranged on the outer wall of the puncture sheath. The visible cerebral ventricle and subdural external drainage system has the remarkable advantages that as the miniature camera can be connected to one end of the visible puncture guiding core, and a monitor is connected to the other end of the visible puncture guiding core, cerebral puncture is completely performed in a direct-viewing mode, precision is improved, and it is avoided that due to operation based on a rule of thumb, the cerebral tissue is damaged, or cerebral hemorrhage occurs. As miniature vanes (fixing clamps) are arranged at the position distant from the cerebral ventricle by 10 cm-15 cm and used for fixing a drainage tube at the incised skin, the defect that a drainage tube used for the current clinic is simply bound and fixed through threads is overcome.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visual ventricle and subdural external drainage system. Background technique [0002] External ventricular drainage or subdural hematoma drainage is an important surgical method for rescuing severe intracranial hemorrhage, obstructive hydrocephalus and intracranial hypertension. The existing external ventricular drainage tube insertion only relies on the doctor’s clinical experience, and the drainage tube cannot be placed in the best position accurately, and the drainage may not be successful due to inaccurate placement; in addition, frequent brain punctures may lead to ventricular catheter insertion. Cause cerebral hemorrhage or ventricular hemorrhage, and then cause intracranial pressure (intracranialcerebralpressure, ICP) to further increase, aggravating the patient's condition.

AI Technical Summary

Problems solved by technology

The existing external ventricular drainage tube insertion only depends on the doctor's clinical experience, and the drainage tube cannot be placed in the best position accurately, and the drainage may not be successful due to inaccurate placement; in addition, frequent brain punctures may lead to ventricular catheter insertion. Cerebral hemorrhage or ventricular hemorrhage will cause further increase in intracranial cerebral pressure (ICP) and aggravate the patient's condition

[0003] If the ventricular catheter is blocked by intraventricular choroid plexus tissue, blood clots, fragments of brain tissue, or fibrin debris, the external drainage may be poor and the operation may fail
