Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiments are only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
As shown in Figure 1, the swell-shrink minimally invasive intervertebral shaping fusing device of the present invention, including conduit 2 and it is connected with conduit
The supporting item 1 of perforation.Supporting item 1 is connected by the oral area 111 being opened on side wall 11 with conduit 2.
Supporting item 1 is trapped among the side wall 11 of surrounding, the upper top surface positioned at side wall upper and lower ends including one（To show internal structure
Upper top surface not shown in figure）With bottom surface 12, the inner space that side wall 11 surrounds has multiple longitudinally disposed partition plates 13, side wall
Be integrally formed with partition plate, it is cellular each chamber 131 that inner space is separated into cross section by partition plate 13, it is cellular can be with
For hexagon, or the shape of cross section of other polygons.In other embodiments, partition plate can also be by inner space
It is separated into cellular each chamber of multilayer.
Through hole 132 is provided with divider plate, the chamber of a portion is formed the first perforation area, it is remaining another
Outer whole chamber forms the second perforation area.Two perforation areas are provided with the present embodiment, in other embodiments, can also be adopted
With a perforation area or multiple perforation areas.Through hole is arranged on partition plate close to the edge of upper top surface or close to the edge of lower top surface
Place, or the different height of central region of partition plate is arranged on, form the arrangement mode to stagger up and down.In other embodiment
In, through hole can also be arranged on other positions.
Be respectively provided with first perforation area and the second perforation area one piece towards supporting item side wall oral area 111 with through hole every
Plate 13a, 13b, allow conduit to be formed and connected with the first perforation area or the second perforation area respectively through supporting item side wall oral area.Pass through
Conduit can inject bone cement into the first perforation area, inject bone filler into the second perforation area respectively.
Conduit and the first perforation area or the connection in the second perforation area, can realize, i.e., by the injection-tube being inserted into from conduit
Be inserted into respectively from the injection-tube of conduit insertion arrive in the first perforation area or the second perforation area towards supporting item side wall oral area
In through hole on partition plate with through hole, bone cement is injected into the first perforation area so as to corresponding, and area is penetrated through to second
Interior injection bone filler.In other embodiments, the connection in conduit and the first perforation area or the second perforation area, can also use
One entrance of the modes such as the three-way pipe of one-to-two, i.e. three-way pipe is connected with conduit, two other outlet is penetrated through with first respectively
Area and the second perforation area correspond to connection.
In other embodiments, side wall, partition plate and bottom surface can also be integrally formed, is linked as again with upper top surface afterwards
One；Or be integrally formed side wall, partition plate and upper top surface, it is connected as a single entity again with bottom surface afterwards.
Supporting item is compressible structure, can enter people by the small notch in Minimally Invasive Surgery with the very small volume of boil down to
Between the adjacent centrum of body any two.By conduit to supporting item internal-filling liquid body or gas, the supporting item of compression is gradually opened up
Open, the supporting item after expansion forms cellular support, and gradually expansion struts soleplate, recovers intervertebral height.
It is preferred that the first perforation area for accommodating bone cement makes note positioned at the outside in the second perforation area for accommodating bone filler
Entering the bone cement in the first perforation area can preferably be supported in periphery, and the bone filler for injecting the second perforation area can be with vertebra
Body soleplate more preferably merges.The respectively filling track of partition plate with through hole has been shown in solid in the perforation of process first area in fig. 2, with
It is shown in phantom by respectively the filling track of the partition plate with through hole, arrow represent injection filling direction in the second perforation area.
Aperture is distributed with upper top surface or/and bottom surface, or uses netted face, in favor of the bone filled in the second perforation area
Filler can preferably be merged with terminal plate of vertebral body.
The one side that upper top surface or/and bottom surface are contacted with terminal plate of vertebral body can also be arranged to rough face or had
The face of multiple lug bosses, so that the bone filler filled in the second perforation area can preferably be merged with terminal plate of vertebral body.
The supporting item uses the material for being suitable for being retained in human body.
The supporting item uses the material with certain flexibility, it is compressed into less volume, by minimally invasive
After small notch in operation is inserted in human body, then external force is applied to it, be softened its forced expansion.
It is preferred that the oral area that supporting item is connected with conduit sets a tying structure, can be by supporting item in oral area after bone grafting
Place ties up to form closing.
The application method of compressible minimally invasive intervertebral shaping fusing device, comprises the following steps：
1. insert the supporting item of compression：The supporting item volume very little of compression, is appointed by the small notch in Minimally Invasive Surgery into human body
Between two adjacent centrums of meaning.
2. the supporting item of compression is unfolded：Supported by conduit to supporting item internal-filling liquid body or gas, liquid or gas
The first perforation area, the second perforation area flowing in part, the supporting item of compression are gradually spread out, the supporting item after expansion forms honeycomb
The support of shape, gradually expansion strut soleplate, recover intervertebral height.
3. note bone cement：An injection-tube is inserted into conduit, injection-tube directly arrives at towards supporting item side wall oral area
In the through hole of the partition plate with through hole in one perforation area, bone cement is injected in the first perforation area into supporting item along injection-tube,
It is retained in by bone cement in supporting item and intervertebral is supported.
4. bone grafting：An injection-tube is inserted into conduit, injection-tube is directly arrived at and passed through towards the second of supporting item side wall oral area
In the through hole of the partition plate with through hole in logical area, bone filler, bee are injected in the second perforation area into supporting item along injection-tube
More bone fillers can be filled into the separate space of nest shape, it is merged more preferably, faster with terminal plate of vertebral body.
When injecting bone cement and bone filler, it will while replace out the liquid or gas of inside.In other embodiment
In, liquid can also be first discharged, reinjects bone cement and bone filler.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
