Abstract
The present invention provides a kind of applied to human body, resist the antigravity device of Ventriculo peritoneal shunt excessively shunting or shunting deficiency caused by position changes, the hydrocephalic Ventriculo peritoneal shunt treatment of neurosurgery is mainly used in, it is characterized in that the function with confrontation caused positional hydrostatic pressing with the position chanP of human body.
Description
Technical field
The present invention relates to applied to human body, resist and excessively shunted after ventriculoperitoneal shunt caused by position changes
Or the antigravity device of shunting deficiency, the hydrocephalic Ventriculo peritoneal shunt treatment of neurosurgery is mainly used in, belongs to surgery doctor
Treat instrument field.
Background technology
Hydrocephalus is neurosurgery common disease, is due to the not smooth caused a kind of disease of cerebrospinal fluid circulation.According to hair
Cause of disease includes craniocerebral trauma, spider because that can be divided into children with congenital hydrocephalus, and secondary hydrocephalus, secondary hydrocephalus
The hydrocephalus caused by factor such as net film lower cavity hemorrhage, encephalitis, neurosurgery be postoperative.It can be divided into height according to the height of intracranial pressure
Pressure property hydrocephalus and normal pressure hydrocephalus.
Hydrocephalus preferred ventriculo-peritoneal shunt in the treatment, the ventricles of the brain-atrium shunting, the ventricles of the brain-mistake shape can also be selected in addition
Sinus shunts, and therapeutic modality, the shunt operation such as the ventricles of the brain-bladder shunting need to apply distribution pipeline, and this is a kind of by ICV brain
Spinal fluid is diverted into the medicine equipment of other lacunas of human body.
At present, the core component clinically for the distribution pipeline for the treatment of of hydrocephalus mainly includes two parts, and one is pressure
Difference limen door, another is hydrostatic pressure resistant difference limen door, and apparatus of the present invention belong to a kind of hydrostatic pressure resistant difference limen door gear.Hydrostatic pressure resistant
Difference is the subject matter for needing to face in current treatment of hydrocephalus, and due to human body, (such as the ventricles of the brain-abdominal cavity is divided after implantable shunt pipeline
Flow art), due to the change of people's position, horizontal position or orthostatic position etc., distribution pipeline both ends can produce and additionally be produced because of difference in height
Raw hydrostatic pressure difference, such as：A normal throw can be produced in people's erectility lower shunt tube head end and abdominal end, and is being lieed down
Under the state of position, this drop disappears with position chanP, due to the change of this drop, after distribution pipeline is implanted into human body just
Extra pressure differential is added, and this continually changing hydrostatic pressure difference is unfavorable for hydrocephalic treatment, such as upright
It can cause excessively to shunt under state, orthostatic headache occurs in patient, and severe patient secondary can intracranial hemorrhage, and under prostrate state divides
Stream deficiency, patient clinical symptom cannot effectively be alleviated, and in face of this problem, that is, hydrostatic pressure resistant difference limen door gear occur.
The hydrostatic pressure resistant valve clinically applied mainly has an anti-siphon means of Medtronic Inc. at present, pungent enlightening under Johnson ＆ Johnson
The volume control device of think of company, Sophysa Inc. and Bei Lang She Pai companies spheroid antigravity device, the domestic and international city in the field

Through casing internal, fluid enters from fluid intake under working condition, acts on for the fluid passage of described device
Spheroid sealing-in, after spheroid sealing-in, liquid outflow port is flowed through, flowed out from fluid issuing.
Pressure at the spheroid sealing-in of described device with human body position change from main regulation process：Preferably, the dress
It is horizontal with human body long axis direction towards human abdomen, long axis direction towards human body head, fluid outlet to put fluid inlet end.
According to the condition of [0021], the pressure change process of horizontal position and orthostatic position is as follows：Gravity turns under horizontal position state
Disk mass by Action of Gravity Field because being rotated to center of gravity minimum point (the minimum direction in left and right two), now, " mass-rotating shaft "
It is more than or equal to 90 degree with " rotating shaft-spheroid sealing-in " angle, gravity rotating disk mass is to the contention effect of lower section arc spring lamination
" 0 ", then arc spring lamination is " 0 " to the contention effect of lower section pressing plate, pressing plate to lower section spheroid without contention effect, at spheroid sealing-in
Naturally block；Under orthostatic position state, gravity rotating disk mass by Action of Gravity Field because being rotated to center of gravity minimum point, now, center of gravity
Minimum point vertical line is parallel with vertical line at spheroid sealing-in, and " mass-rotating shaft " is equal to " 0 " with " rotating shaft-spheroid sealing-in " angle, quality
Block reaches maximum to the contention effect of lower section arc spring lamination, and then arc spring lamination is maximum to the contention effect of lower section pressing plate
Value, pressing plate are maximum to the contention effect of lower section spheroid, pressure highest at spheroid sealing-in.
Pressure change process of the described device between horizontal position and orthostatic position during transition：Between horizontal position and orthostatic position
During transition, " mass-rotating shaft " and " rotating shaft-spheroid sealing-in " angle fluctuates between 0-90 degree, and then mass is to lower section arc
The contention effect of shape shell fragment changes in " 0 " between maximum, changes with the difference of position, pressure of the mass to arc spring lamination
Compel effect and produce different changes, i.e., " mass-rotating shaft " gets over the pressure at spherula sealing-in with " rotating shaft-spheroid sealing-in " angle
Bigger, " mass-rotating shaft " and the pressure at the bigger spheroid sealing-in of " rotating shaft-spheroid sealing-in " angle are smaller, are adapted to so as to produce
The different height of human body position change is poor, i.e. the pressure change of hydrostatic pressure difference.
The fluid process of circulation of described device：According to the condition of [0021], head end is adds additional under person upright's state
With the hydrostatic pressure difference of abdominal end, according to the setting of described device, the pressure during position at spheroid sealing-in is exactly erectility
Lower extra increased hydrostatic pressing, now, the fluid cavity that fluid is entered in housing by fluid intake, acts on spheroid sealing-in
Place, fluid, by liquid outflow port, are flowed out by spheroid sealing-in from fluid outlet.When human body horizontal position, head end and abdominal cavity
The extra hydrostatic pressure differential collapses at end, now, blocked at spheroid sealing-in for nature, no extra pressure, so as to not increase fluid resistance,
And between orthostatic position and horizontal position during transition, because extra increased hydrostatic pressure difference is by gravity rotating disk matter caused by position difference
The different pressures that gauge block is acted at spheroid sealing-in change and offset, and then avoid excessive shunting and the horizontal position under erectility
Shunting deficiency under state.
Purposes of the described device in the medicine equipment for preparing the diseases such as treatment hydrocephalus.It can become according to human body position
The difference of change, and the extra increased hydrostatic pressure difference to create antagonism under different position states of adaptability, to adapt to clinical treatment
Demand.
