Embodiment Construction

[0012] exist figure 1 , figure 2 In the process, a new type of ventricle shunt tube pressure control valve (1) is buried under the chest skin, the shunt tube in the chest wall subcutaneous tunnel is cut into two ends, and then connected to the shunt tube interface (1) at both ends of the control valve. Suture the fixing hole (10) on the rigid polypropylene plastic base to the pectoralis major with silk thread to fix it. The soft partition (7) is pressed by rotating the pressure control valve (6) to change the internal pressure of the cuboid liquid storage bag (8), thereby adjusting the internal pressure of the shunt tube. The titanium alloy ball (3) in the oval liquid storage bag (2) can be blocked at the baffle plate (4) of the opening due to changes in body position, and the outlet area is reduced, thereby reducing the liquid flow rate. Because of the protection of the protective film (5), the activity of the pressure control valve will not be affected by soft tissues suc...

Abstract

The invention relates to a novel ventricular shunt pipe pressure control valve. The technical scheme includes that two liquid storage sacs which are communicated in the middle are disposed on a rigid base, and the side of each liquid storage sac is provided with a shunt pipe interface; a titanium alloy ball (3) added in one sac can be retained by a retaining board after rolling and falling down so as not to enclose the outlet of the liquid storage sac; a flexible partition board (7) added in the other sac is additionally provided with a control valve (6) on the outer side thereof so as to allow the fingers to rotate a pressure control valve to control the inner pressure of the sac. The novel ventricular shunt pipe pressure control valve is simple to operate and free of affect of the magnetic force. The inner pressure of the sac can be changed according to the position changes of a patient, complications after the ventricular and peritoneal shunt are greatly reduced, the probability of reoperation of the patient is reduced, so that medical cost is saved, and clinical practical value and economic benefit highly are produced. As is shown in the attached figure of the abstract, the control valve is composed of two liquid storage sacs, one is provided with the titanium alloy ball, and the other is provided with the flexible partition board.

Description

technical field [0001] The present invention designs a medical device for neurosurgery, especially a new type of pressure regulating valve for ventricle shunt tube used for treating hydrocephalus. , not limited by MRI examination. Background technique [0002] It has been nearly a hundred years since Kausch first applied ventriculoperitoneal shunt (V-P shunt) to treat hydrocephalus. The use of V-P shunt in the treatment of hydrocephalus has solved the pain of many patients and saved many lives. The continuous improvement of shunt devices and shunt technology has always been accompanied by the development of shunts. The purpose is to minimize the number of shunts. complications. Nevertheless, various shunt failures still appear one after another, making it the biggest obstacle in the treatment of hydrocephalus. Some scholars reviewed the 50-year history of shunt surgery and pointed out that the failure rate of shunt surgery was 40% in 1 year and 50% in 2 years, and excessi...
