Description
Technical field
The present invention relates to hydrocephalus tricorn peritoneal shunt technical field, specifically a kind of ventricles of the brain-abdominal cavity shunt device of cerebrospinal fluid.
Background technology
For intracranial infection need merge hydrocephalic patient, on clinical medicine, generally adopt through lateral ventricular external drainage art or lumbar cistern drainage art.Lateral ventricular external drainage art is that the cerebrospinal fluid that Intraventricular is accumulated absorbs through abdominal cavity, thereby cerebrospinal fluid is absorbed and secretion complete equipilibrium.Best shunt volume and corresponding intracranial pressure vary with each individual, the pressure-regulating device that the part flow arrangement of application adopts mostly at present is compression pump, substantially only there are high pressure shelves, middle pressure shelves and three gears of low pressure shelves, its part flow arrangement pressure selection is limited, in practical clinical, be difficult to select patient's optimum pressure, and be difficult to make according to patient's change of illness state the adjustment of continuous pressure and drainage flow, cause clinically approximately 50% shunt operation patient isocon pressure selection not good, part even needs again to perform the operation, and increases misery to patient.
Summary of the invention
Technical problem to be solved by this invention is that to overcome in prior art part flow arrangement pressure selection limited, is difficult to make according to patient's change of illness state the defect that continuous pressure and drainage flow are adjusted, and a kind of ventricles of the brain-abdominal cavity shunt device of cerebrospinal fluid is provided.
The present invention for addressing the above problem adopted technical scheme is: a kind of ventricles of the brain-abdominal cavity shunt device of cerebrospinal fluid, this part flow arrangement comprises that one for inserting the subcutaneous external water capsule in patient abdominal cavity and one for the conduit to abdominal cavity by ICV drainage of cerebrospinal fluid, on the outer wall of described conduit, be arranged with an interior water pocket for extruded conduit, interior water pocket is communicated with external water capsule by water injection pipe, and water injection pipe is provided with the check valve for water pocket in external water capsule liquid is introduced, described interior water pocket is provided with one for discharging the liquid pumping hole of its inner chamber liquid, this liquid pumping hole seals for the silica gel sealing pad that thrusts liquid pumping needle by one.
In clinical practice of the present invention, water injection pipe, external water capsule and conduit are flexible medical material, and one end of conduit is used for inserting patient's Intraventricular, and the other end is used for inserting patient abdominal cavity.External water capsule is placed in to patient abdominal cavity subcutaneous, push external water capsule by medical personnel from in-vitro percutaneous skin, by the water pocket in water injection pipe injects of liquid in external water capsule, interior water pocket can produce squeezing action to the conduit outer wall of its sandwiched, thereby adjusts the drainage flow of cerebrospinal fluid in sleeve pipe.And can play squeezing action to the conduit of its sandwiched in order to realize interior water pocket, can be sheathed for being pressed together on the plastic conduit on conduit outer wall on the outer peripheral face of interior water pocket; Or the wall that interior water pocket contacts with conduit is set to flexible medical material, as silastic material, the outside wall surface of interior water pocket is set to hard medical material, as High molecular weight polyethylene material.
According to clinical practical application, the length of conduit is set to 500 ~ 750mm the best.
In the present invention, interior water pocket is wrapped in conduit outer wall ringwise, the hard medical material of the plastic conduit of interior water pocket outer wall or outside wall surface, internally water pocket plays effect of contraction, when after water pocket in liquid injection, interior water pocket starts to expand and inside extruded conduit, and the internal diameter of conduit is dwindled, and the drainage flow of catheter interior cerebrospinal fluid diminishes thereupon.
Beneficial effect: this part flow arrangement in use, need entirety to be embedded in patient body, medical personnel are placed in the subcutaneous external water capsule in patient abdominal cavity through in-vitro percutaneous skin extruding, can be by the water pocket in water injection pipe injects of the liquid in external water capsule, interior water pocket expands the catheter diameter of its sandwiched is dwindled, thereby adjusts the drainage flow of cerebrospinal fluid in conduit;
In the time that in interior water pocket, fluid pressure is excessive, can be by external use syringe, liquid pumping needle is thrust to interior water pocket by liquid pumping hole, the liquid of certain volume in water pocket in extracting, complete the adjusting of fluid pressure in interior water pocket, make the realistic circulation needs of the drainage flow of cerebrospinal fluid in conduit, and because silica gel sealing pad elasticity is higher, after liquid pumping needle detaches, the passage that silica gel sealing pad can rely on the elastic closure syringe needle of self to form;
This part flow arrangement can be adjusted the volume in external water capsule and interior water pocket in the preoperative, in clinical use, in the time that drainage of cerebrospinal fluid amount is excessive, can make by pressing external water capsule the flow of water pocket correction conduit cerebrospinal fluid in liquid injection wherein, press at every turn the added flow that increases liquid in interior water pocket can be measured in the preoperative.The present invention realizes the adjustment of cerebrospinal fluid drainage flow in conduit by the quantitative change in volume of liquid, there is good clinical safety, meet the circulating pressure needs of cerebrospinal fluid, and be better than traditional pressure-regulating device reducing aspect the excessive and not enough complication of shunting, drain for a long time, alleviation hydrocephalus, until cerebrospinal fluid recovers normal level, can reduce the misery that patient performs the operation again, alleviate individual financial burden and burden on society.
