Description
Technical field
The present invention relates to a kind of surgery readings of shunt body external pressure and regulating device, are mainly used in pressure-adjustable shunting
The external pressure of pipe is read, and carries out pressure setting, belongs to surgical medical equipment field.
Background technology
Hydrocephalus is neurosurgery common disease, is a kind of disease caused by cerebrospinal fluid circulation is unsmooth, cerebrospinal fluid
Cycle is a part for normal person's physiological cycle, and cerebrospinal fluid is generated by the choroid plexus of telocoele, enters three ventricles of the brain by side opening,
Enter Fourth ventricule and myelocoele by mesotube, after flow through Fourth ventricule medium pore and side opening enters brain surface arachnoid
Cavity of resorption, the absorbed into serum at arachnoid villi, into the blood circulation of human body, the daily cerebrospinal fluid secretory volume of normal person is about
The cerebrospinal fluid amount of 350-500ml, normal ventricular system are about 150-300ml, therefore when the secretory volume of cerebrospinal fluid is more than uptake
It just will appear the ventricles of the brain gradually to expand, then develop into hydrocephalus.Hydrocephalus can be divided into communicating hydrocephalus according to type, i.e., by
Unsmooth cause is absorbed in cerebrospinal fluid；Internal hydrocephaly has the position of obstruction in cerebrospinal fluid circulation access, such as：Tumour
Compressing etc..It can be divided into children with congenital hydrocephalus and secondary hydrocephalus according to pathogenic factor, be wrapped in secondary hydrocephalus
Include hydrocephalus caused by the factors such as craniocerebral trauma, subarachnoid hemorrhage, encephalitis, neurosurgery be postoperative.According to intracranial pressure
Height can be divided into hypertensive hydrocephalus and normal pressure hydrocephalus.
Hydrocephalus preferred ventriculo-peritoneal shunt in the treatment, in addition can also select the ventricles of the brain-atrium shunting, the ventricles of the brain-mistake shape
Sinus shunts, and the therapeutic modalities such as the ventricles of the brain-bladder shunting, shunt operation needs to apply isocon, and isocon is divided into constant pressure shunting at present
Pipe, i.e., can not carry out pressure controlled isocon and pressure adjustable type isocon, you can set to adjust isocon as needed
The pressure set.Due to the continually changing feature of particularity and pressure of ventricular system, therefore pressure-adjustable isocon more meets physiology
Feature is also more suitable for neurosurgery needs.
Currently, the pressure adjustable type isocon clinically applied is essentially from Johnson ＆ Johnson of the U.S., U.S.'s Medtronic, the German bright snake of shellfish
The external pressure of board, the product of French Sophysa Inc., each producer's isocon is read and external voltage-regulation principle is different, than
Such as：The external wireless servo motor in electric control isocon that Johnson Co. uses carries out pressure regulation；U.S.'s Medtronic is public
Department is read using needle, magnet pressure regulation；The German bright snake board of shellfish is read using needle, being unlocked by pressing pressure regulation；French Suo Feisa is used
Needle is read, and magnetic key operated lock unlocks pressure regulation etc..In the present invention, inventor uses completely new external pressure data reading and pressure
Regulation technology, i.e. magnetic fluid positioning pressure are read and the mode of pressure unlock rotation pressure regulation, compared to above-mentioned 4 company
Reading technology is more direct, and can be good at realizing external pressure value visualization reading and accurate pressure set-up function.
