Abstract
The invention discloses a medical instrument for regulating the pressure of a shunt pipe after the ventriculoperitoneal shunt surgery is used for clinically treating hydrocephalus. The medical instrument is characterized in that a place, where a shunt pipe passes through the pectoralis major, is embedded with a control valve, and the shunt pipe is arranged in the control valve. The control valve is fixed on the pectoralis major. An operation rod is arranged on the control valve to be protected by a protective cover, thus the limit to the swinging of the operation rod can be prevented after the skin is ankylosed. The operating rod is mechanically swung according to iconography expression of post-operative check-up so that an elliptical body at the lower end of the operating rod presses the shunt pipe to ensure that the internal pressure of the shunt pipe raises for regulating the internal pressure of the shunt pipe, and the internal pressure range of the shunt pipe can range from the complete opening to the complete closing. The pressure control valve of the shunt pipe is simple in operation, can be operated at any time and moment without being influenced by outside magnetic force, has a wide pressure change range inside the pipe, and can be used in various shunt surgeries. The medical instrument is shown in summary figures, and the shunt pipe passes through a tunnel in the control valve, and the operating rod outside the shunt pipe can be used for regulating the internal pressure of the shunt pipe.
Description
Technical field
The present invention designs the medical apparatus and instruments that a kind of neurosurgery is used; Particularly a kind ofly treat the ventricular shunt pipe pressure control valve that hydrocephalus is used; It is intrinsic pressure that this valve not only can mechanical random regulation and control isocon, and not influenced by field of magnetic forece, do not receive the restriction of magnetic resonance examination.
Background technology
Last 100 years since Kausch first Application ventriculo-peritoneal shunt (V-P bypass) treatment hydrocephalus.It is that many patients have solved slight illness and saved many life that the V-P bypass is used to treat hydrocephalus; The updating of constantly perfect and dividing technology of part flow arrangement is accompanied by the bypass development all the time, and its purpose is exactly to reduce the complication of bypass to greatest extent.However, shunt fault of all kindsly and still occur successively, make it to become obstacle maximum in the treatment of hydrocephalus.Have the scholar to look back 50 years of bypass and point out that 1 year mortality of bypass is that 40%, 2 year mortality reaches 50% when historical, wherein shunting excessively is exactly one of very common reason.There is not timely adjust blood pressure if the intrinsic pressure mistake of isocon is low; Just cause shunting easily excessively, shunting excessively is prone to cause subdural hematoma, low intracranial pressure syndrome or ventricles of the brain crack syndrome, if serious symptom; Often need operation once more to extract isocon or ligation isocon; Treat after the intracranial improving situation that operation is placed or the isocon of loosening once more, if like this, a patient possibly need experience 3 times even operation more frequently; Cause suffering not only for patient's psychosoma, and increased patient's financial burden and operation risk.In order to prevent to shunt the misery of excessively bringing to the patient, but invented various adjust blood pressure isocons clinically, its pressure valve can be according to the Radiologic imaging adjust blood pressure gradually of postoperative check; But because existing pressure regulating valve is how relevant with magnetic force; Can receive the influence of magnetic resonance examination, each in addition control valve pressure all needs producer to carry specific instrument to carry out adjust blood pressure, if postoperative burst shunting excessively; Or the patient leaves hospital back generation shunting excessively, very inconvenience of adjust blood pressure so.If shunting takes place excessively after the bypass, cause situation such as subdural hemorrhage, low intracranial pressure syndrome or ventricles of the brain crack syndrome, often need the temporary close isocon, but and existing pressure regulating valve can not reach this purpose.In addition, mostly normal clinically now isocon device that uses is external import, and price is more expensive, and this has also increased financial burden for the patient, thereby has also limited its extensive use.
Summary of the invention
Existing isocon is shunted excessively easily in order to overcome, pressure regulating valve is subject to shortcomings such as magnetic force influence, adjust blood pressure inconvenience.The invention provides a kind of ventricular shunt pipe pressure control valve.This isocon pressure-control valve is a mechanical operation, does not receive the influence of magnetic force, anytime anywhere can regulate the isocon internal pressure as required, and can close isocon as required.This isocon is low price not only, and easy to operate, can reach pressure controlled various requirement after the clinical hydrocephalus bypass, has reduced medical treatment cost, has also avoided the risk of operation once more, has improved the success rate of shunt operation.
The technical scheme that the present invention solves its technical problem employing is: ventricular shunt pipe pressure control valve is the cube of a 2cm * 2cm * 0.5cm, and an inclined to one side side has a tunnel that is parallel to sidewall, and internal diameter is big slightly than the isocon caliber; The tunnel communicates with a sidewall; Isocon can be packed in the tunnel through sidewall, a draw-in groove is arranged, in the time of in isocon is packed pipeline in the sidewall; Draw-in groove is embedded in card, and isocon promptly is stuck and can't shifts out.The tunnel opposite side is a knob, and the knob lower end is an irregular ellipsoid body, can stop up the tunnel with knob, and tunnel, irregular ellipsoid body are all inner at cube; The knob upper end connects an action bars outside cube; Action bars, knob, ellipsoid body are connected as a single entity; Action bars can drive ellipsoid body half-twist through driving knob, and an over cap is installed in the action bars outside, and action bars can rotate back and forth at over cap with between above the cube.The over cap upper end is marked with 2 scale marks of projection slightly, and its value is meant 30 °, 60 °.
The invention has the beneficial effects as follows; The ventricular shunt pipe is from the head after the abdominal cavity is gone in subcutaneous tunnel; At chest control valve is imbedded the subcutaneous pectoralis major place of being fixed in, isocon is packed in the control valve, the action bars above the rotation makes inner irregular ellipsoid body rotation compressing isocon; Can make that isocon is intrinsic pressure to be increased, thereby the adjustment isocon is intrinsic pressure.Because of action bars has the over cap protection, even the skin ankylose also is difficult for the swing of overslaugh action bars.In addition, knob can increase frictional force because of the milled sand surface contact is arranged, and is unlikely slippage after the rotation.Graduation mark on over cap sign has 30 °, 60 °, expression be the anglec of rotation of action bars, also represent the force value of certain limit in the isocon.Control wealthyly because be mechanical operation, do not receive that magnetic resonance is isomagnetic to be influenced.The adjustment of control valve pressure does not need special instrument, does not need producer's adjustment yet, only needs the medical worker who understands this equipment just can operate.This valve is that rigid plastics is processed, and does not have rejection with human body.
This invention is simple to operate, easy to use, curative effect is splendid, not only can adjust valve pressure at any time, can not influenced by magnetic force again, has improved the shunt operation success rate greatly, has reduced medical expense, and high value for clinical application and economic results in society are arranged.
