Description

Neurosurgery's ventricles of brain drainage tube clamping device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a ventricular drainage tube clamping device for neurosurgery.

Background

The intracranial volume is increased by various pathogenic factors, the cerebrospinal fluid pressure measured by lateral position lumbar puncture exceeds 1.92kpa, namely the intracranial pressure is increased, if a series of clinical manifestations such as headache, vomit, visual disturbance and papillary edema appear, the intracranial pressure increase syndrome is called, according to the Monroe-kellie principle, except that the blood vessel is communicated with the outside of the skull, the cranial cavity including the spinal cavity connected with the cranial cavity can be basically used as an inextensible container, and the total volume of the cranial cavity is unchanged.

The intracranial contents comprise three contents, namely brain tissues, blood and cerebrospinal fluid, the volumes of the three contents can not be compressed but can be compensated within a certain range, the total volume of the cranial cavity is not changed, and the volumes of the cranial contents can be changed under different physiological and pathological conditions, so the contradiction between the cranial contents and the cranial contents is formed, accurate physiological regulation is needed to ensure the balance between the cranial contents and the cranial contents, if the volume of a certain part of the cranial contents is increased, compensatory reduction of other parts is inevitably caused to adapt, the basic principle of maintaining normal intracranial pressure is adopted, and if the volume of the part of the cranial contents is exceeded a certain limit, the mechanism can be damaged, and the intracranial pressure can be increased.

Of the three contents, the volume of brain tissue is the largest, but the effect on volume compensation is the smallest, normal intracranial pressure is maintained mainly by compressing cerebrospinal fluid and cerebral blood flow, generally, the volume of the contents in the cranial cavity is increased by 5% and can be compensated, when the volume is more than 8-10%, obvious intracranial pressure increase occurs, the volume of the contents in the cranial cavity can be increased due to cerebral edema, cerebrospinal fluid amount or cerebral blood flow increase, intracranial space occupying lesion and the like caused by various reasons, for example, the contents in the cranial cavity are normal, when the volume of the cranial cavity is reduced due to encephalic deformity, skull base depression, skull osteoma, malformed osteitis or skull sunken fracture and the like, the intracranial pressure can also be increased, and on the aspect of clinical medical treatment means, the intracranial pressure is usually directly released, and a drainage tube is needed for releasing the intracranial pressure.

At present, when a drainage tube is fixed for a patient needing ventricular drainage, an adhesive tape is usually used for being stuck on the scalp, and then gauze is used for wrapping the head so as to prevent the drainage tube from falling off, but the method has the following problems:

1. when the drainage part needs to be operated, the operation can be carried out only after the gauze is completely disassembled, the stability of the drainage tube is inevitably influenced in the process of disassembling the gauze, and if the drainage tube is pulled, great potential safety hazard is brought to the ventricular patient for drainage;

2. when gauze is used for wrapping, the head and the drainage part of the patient cannot be ventilated;

3. the existing drainage tube clamping devices generally apply clamping force to the drainage tube directly, but the drainage tube is clamped flatly and blocked due to too large clamping force, and the drainage tube cannot be effectively fixed due to small clamping force.

Therefore, the present invention provides a neurosurgical ventricular drainage tube clamping device to solve the above problems.
