Pipe is cut off by sharp piercing needle, is caused conduit to fracture and is stayed in patient's spinal cavity；Also it is exactly that conventional lumbosacral spine punctures
Function of the drainage system without regulation flow.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of band air bag flow-controllable lumbosacral spine puncturing drainage apparatus, this
The flexible conduit of kind lumbosacral spine puncturing drainage apparatus is easier to insert spinal cavity, and will not fracture and slip, and can also accurately control
Vertebra flow quantity processed.
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of band air bag flow-controllable lumbosacral spine and worn
Drainage system is pierced, including the trocar with outer casing needle and nook closing member, triple valve, receipts sample pipe and receipts sample bag, the nook closing member are located at overcoat
Inside pin, a port of the triple valve is connected by mozzle with receiving sample pipe, and the receipts sample pipe and receipts sample bag pass through water conservancy diversion
Pipe connects, the set pin puncture enter spinal cavity after, exit nook closing member, insertion is internal in the outer casing needle leads equipped with the soft of seal wire
Pipe, the thickness of the seal wire and the internal diameter of flexible conduit match, seal wire enter spinal cavity after, exit outer casing needle, guided by seal wire
Flexible conduit enter spinal cavity after, exit seal wire, another port connection of the flexible conduit and triple valve, the flexible conduit is pierced into
One end of spinal cavity is provided with inflatable airbag, and flow control valve is provided between the triple valve and receipts sample pipe.
The flexible conduit tube wall is provided with the gas tube connected with air bag.
The air bag is arranged at flexible conduit head end 6cm.
The anterior frustoconical for round and smooth top of the seal wire.
The top stray circle center of the seal wire, positioned at circumferential position.
The flow control valve is positioned close at triple valve.
Beneficial effect
Seal wire guiding equipped with thickness matching when the flexible conduit of the present invention enters spinal cavity, the front portion of seal wire is taper knot
Structure, flexible conduit is set to be easier to insert in outer casing needle, and seal wire is located inside flexible conduit, can effectively prevent that flexible conduit is sharp
Outer casing needle syringe needle cut off；The head end that flexible conduit is pierced into spinal cord cavity gap sets air bag, can play after airbag aeration and be led soft
Pipe is fixed on the effect of spinal cord cavity gap so that flexible conduit will not slip in use；Triple valve with receive sample pipe it
Between flow control valve is set, can accurately control the flow of cerebrospinal fluid, and the flow control valve can be positioned close to triple valve
Position, make control structure in device compact.
Brief description of the drawings
Fig. 1 is the structural representation after flexible conduit of the trocar of the present invention insertion equipped with seal wire.
Fig. 2 is the structural representation of puncturing drainage apparatus of the present invention.
Wherein：1 is outer casing needle, and 2 be flexible conduit, and 3 be seal wire, and 4 be air bag, and 5 be gas tube, and 6 be triple valve, and 7 be flow
Control valve, 8 is receive sample pipe, and 9 is receive sample bag, and 10 be trocar.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
A kind of band air bag flow-controllable lumbosacral spine puncturing drainage apparatus as illustrated in fig. 1 and 2, including trocar 10, triple valve
6th, to receive sample pipe 8 and receive sample bag 9, trocar 10 is made up of outer casing needle 1 and nook closing member, and nook closing member is located inside outer casing needle 1, and the one of triple valve 6
