Description
Technical field
This utility model relates to a kind of neurosurgery clinical treatment apparatus, especially a kind of neurosurgery cerebral edema drainage system.
Background technology
Occur that the patient of cerebral hemorrhage or cerebral thrombosis is usually with symptoms such as intracranial pressure risings, conventional treatment means is exactly the hydrops reduction intracranial pressure of being discharged intracranial by drain.Chinese utility model patent CN 203043073 U discloses a kind of cerebral edema drainage device, direct use exterior airbag carries out stopping blooding and fixing, this structure can play good hemostasis and fixation when normal use, but receive external force accident collision at sting device, there will be larger angle, the change of position, very high risk can be caused to patient.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of neurosurgery cerebral edema drainage system, the deficiencies in the prior art can be solved, improving the fixed structure of drainage system, making it also can keep relative stable when receiving external force collision, reduce patient and to meet accident the risk of damage.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of neurosurgery cerebral edema drainage system, comprise fixed block, run through in fixed block and be plugged with silica gel drainage tube, described fixed block comprises the first hard layer, second hard layer, rubber layer is bonded with between first hard layer and the second hard layer, the seam crossing of rubber layer and the first hard layer and the second hard layer is respectively arranged with rubber flange, also fixed by connecting rod between first hard layer and the second hard layer, annular air-pocket is provided with bottom second hard layer, the external diameter of annular air-pocket is greater than the external diameter of the second hard layer, turn is provided with in first hard layer, hard metal circle is provided with in second hard layer, the inwall of hard metal circle is provided with arcwall face protruding to the inside, turn and hard metal circle are coaxially arranged, silica gel drainage tube passes from turn and hard metal circle inside, and with turn and hard metal circle interference fit.
As preferably, in described silica gel drainage tube, be provided with inner sleeve.
As preferably, described silica gel drainage tube is provided with universal joint, and universal joint is positioned at the top of the first hard layer.
The beneficial effect adopting technique scheme to bring is: this utility model changes in prior art the structure directly using air bag to be fixed drainage tube; be fixed in the conduction hole of skull by using fixed block; by fixed block, drainage tube is fixed again; utilize the cushioning balance effect of fixed block active force to external world, realize the effect of protection patient.When silica gel drainage tube receives external force collision effect, the trend that silica gel drainage tube can rotate towards Impact direction, the trend of this rotation to be squeezed power and elastic deformation occurs and then is applied on the first hard layer by turn, simultaneously, silica gel drainage tube and hard metal circle extrude mutually, to another active force of the second hard layer.Two active forces be applied on the first hard layer and the second hard layer produce a torsion force to whole fixed block under the buffering negative function of connecting rod, this torsion force is finally issued to balance in the effect of self micro-deformation of rubber layer, thus maintain the basicly stable of whole fixed block, the change of significantly position and angle can not be there is.The arcwall face of hard metal circle inner bulge can make the interaction force of silica gel drainage tube and hard metal circle substantially remain on horizontal direction, reduces the active force of its vertical direction.Annular air-pocket is used for cushioning the active force of the vertical direction that fixed block is subject to and limiting, and ensures the relatively stable of fixed block vertical direction.Rubber flange can produce compressional deformation with the medial wall of conduction hole after fixed block is plugged on skull conduction hole, thus improves the first hard layer, stability that the second hard layer is fixedly connected with rubber layer and the sealing between fixed block and conduction hole.Inner sleeve can be used for drain regional injection medicine in drainage process, accelerates the disappearance of edema and thrombosis.Silica gel drainage tube, can so that the adjustment of silica gel drainage tube top-direction by design universal joint, by the break-in of universal joint simultaneously when being subject to impact force at top, greatly can reducing impact force and be passed to size on fixed block.
