Abstract
The utility model discloses a kind of intervertenral space injection-type bone grafting funnels, including funnel, funnel efferent duct, plugging cap and inject interior bolt three parts, the funnel efferent duct is located at funnel bottom, the plugging cap is described to inject interior bolt for injecting the filler in funnel efferent duct for encapsulating funnel efferent duct.After the funnel and plugging cap of the utility model combine, broken bone can be packed into funnel, and can read and be packed into broken bone volume；Plugging cap is unloaded later, and injection-type bone grafting can be carried out by loading onto after bolt in injection-type.
Description
Technical field
The utility model relates to bone surgery specific purpose tools, and in particular to a kind of intervertenral space injection-type bone grafting funnel.
Background technique
For lumbar degenerative slippage, Segmental defect, discogenic disease, lumbar spinal stenosis, traumatic lumbar vertebrae
Low back pain, lower extremity movement sensory disturbance caused by lumbar instability caused by slipping, conservative therapy nonresponder clinically generally need row waist
Fusion is fixed in vertebra.During surgery, often need in the intervertenral space for having removed interverbebral disc and cartilage endplate bone grafting to reach
Bony union obtains long-term stablizing effect.Clinically used intervertenral space bone grafting funnel at present, because its is inconvenient for use, patient
Be partial to using 1ml syringe, distal end cut and fill in broken bone and carry out injection-type bone grafting, but because when carrying out broken bone and loading without
Method effectively blocks distal end, and when filling, broken bone was easy to spread out and time-consuming and laborious, extends operating time, reduces operating efficiency.
Summary of the invention
For the defects or inadequacies for existing technologies, the utility model provides a kind of intervertenral space injection-type bone grafting funnel, packet
It includes funnel, funnel efferent duct, plugging cap and injects interior bolt three parts, the funnel efferent duct is located at funnel bottom, the closure
Cap is described to inject interior bolt for injecting the filler in funnel efferent duct for encapsulating funnel efferent duct.
In a kind of embodiment, the end of the funnel efferent duct of the utility model is equipped with external screw thread, and the plugging cap is equipped with
Internal screw thread, the external screw thread and internal screw thread engagement.
In a kind of embodiment, the interior bolt of injecting of the utility model is T-type structure.
In a kind of embodiment, the funnel of the utility model is equipped with volume markings value.
In a kind of embodiment, anti-skidding external screw thread is equipped with outside the funnel of the utility model.
In a kind of embodiment, there is anti-skidding external screw thread outside the closure nut of the utility model.
In a kind of embodiment, the funnel output bore of the utility model is 4mm.
The technical characterstic of the intervertenral space injection-type bone grafting funnel of the utility model is, funnel distal end be can plugging structure, just
In the loading of broken bone.There is scale value in infundibular body portion, can read broken bone volume；Bolt can inject broken bone into intervertenral space in injection-type,
Realize efficiently and effectively bone grafting.

Specific embodiment
The utility model provides a kind of intervertenral space injection-type bone grafting funnel comprising funnel 1, blocks funnel efferent duct 4
Cap 2 and inject interior bolt 3.
In a kind of embodiment, 4 end of funnel efferent duct is equipped with external screw thread, and internal screw thread, and the interior spiral shell are equipped in plugging cap 2
Line is engaged with external screw thread, when being packed into broken bone into funnel, realizes the temporary envelope to 4 end of funnel efferent duct using plugging cap 2
It is stifled to be packed into this process of funnel up to completing broken bone.After the loading for completing broken bone, it is inserted into funnel 1 and funnel efferent duct 4
Interior bolt 3 is injected, and sheds plugging cap 2, funnel efferent duct 4 is protruded into intervertenral space, that injects interior bolt 3 injects handle, will be broken
Bone implant intervertenral space.
In an alternate embodiment, transparent organic glass production, infundibular body portion band is can be used in the funnel of the utility model
There is volume markings value, can intuitively observe the volume for being implanted into broken bone, is also convenient for patient and observes the case where broken bone enters intervertenral space.
Antiskid thread can be equipped in preferred scheme, outside funnel can prevent funnel from patient when carrying out injecting bone grafting
It is slipped in hand.
Another kind has in the scheme of choosing, and the funnel internal diameter of the utility model is 4mm.
For convenience of operation, it is equipped with antiskid thread outside the closure nut of the utility model, patient is made to be easy to that nut will be blocked
With funnel distal end rotary assembled.
In preferred scheme, the interior bolt of injecting of the utility model is T-type structure, facilitates patient more labour-saving by broken bone
It injects into intervertenral space.
Embodiment:
With reference to Fig. 1,2,3, the intervertenral space injection-type bone grafting funnel of the embodiment includes: funnel 1, funnel efferent duct 4, blocks
Cap 2 and inject interior bolt 3.
Funnel 1 and funnel efferent duct 4 are hollow structure, and 1 distal end of funnel is outer equipped with what can be engaged with 2 internal screw thread of plugging cap
Volume markings value is carved in screw thread 11, infundibular body portion, and funnel 1 has anti-skidding external screw thread 12.
There is the internal screw thread that can be combined with funnel distal end external screw thread 11 inside plugging cap 2, there is anti-skidding external screw thread in outside.
Injecting interior 3 distal end of bolt is injection-type head 31, and proximal end is that T-type injects handle 32.
Injection-type bone grafting funnel entire use process is as follows:
Plugging cap 2 and 1 distal end external screw thread 11 of funnel are combined by screw thread, realize the temporary closure to funnel distal end.
It is packed into the broken bone trimmed from funnel horn opening position, only broken bone of the diameter less than 4mm can just be packed into funnel, benefit
It is filled in bolt 3 in injection-type and is suitably pressurizeed, the volume for being packed into broken bone is determined from the volume markings value in infundibular body portion.To broken
After bone loads, the head 31 of bolt 3 in injection-type is filled in after funnel and is suitably pressurizeed, plugging cap 2 is shed.Patient shows finger
The anti-skidding external screw thread 12 of funnel is clamped with middle finger, thumb is placed on the T-type handle 32 of bolt in injection-type, and needs are protruded into funnel distal end
The intervertenral space of bone grafting, thumb push T-type handle 32 to inject broken bone into intervertenral space, complete bone grafting process.
