Description
Technical field
The utility model relates to a kind of Medical Devices, the molding die of specifically a kind of intervertebral bone grafting block is suitable for intervertebral
Plant bone mass.
Background technique
Many spinal surgeries often need that pedicle screw is fixed and posterior decompression bone grafting, the type of interbody fusion are numerous
It is more, certain curative effect is played to promotion intervertebral fusion.But there is also some shortcomings, such as: currently used same by support C age+
Kind allograph bone/artificial bone implantation, often may occur in which such as: rejection, fusion device sink, dural sac, mind are oppressed in displacement
Through and cause spinal nerve to be pressurized, nonunion, infection etc. or even has the danger for causing blood borne disease；These bones need simultaneously
The creeping substitution mode growth time wanted is longer, therefore needs long time to merge, moreover since carrier material is special, and expense is high
It is expensive, increase the financial burden of patient.For another example: at present by the way of self skeletal grain impaction bone grafting, bone particle, which has, to dissociate to vertebra
The undesirable problem of the possibility and intervertebral pulling effect of pipe, and autologous bone is that bone is taken from ilium, and bone is taken to there is transplanting in the process
Bone block height is lost, for complication such as the infection of bone area, long pains.It itself is taken brought by bone concurrently though allograph bone avoids
Disease, but lead to Fusion failure, infection there are rejection, or even cause the generation of Hematogenic infectious disease, and cannot be effective
Support maintains intervertebral height, it is also possible to osseous granules easily be entered to canalis spinalis or suppressed to peritonaeum, there is certain risk.
The utility model of Authorization Notice No. CN202168873U provides a kind of molding die of intervertebral bone grafting block, including lower die
Body, upper die body and die module, wherein the mold cavity shapes of lower mold body are designed to and its depth root consistent with the shape of plant bone mass
It is arranged in proportion according to the thickness of plant bone mass, the position limiting structure being equipped between upper die body and lower mold body, after broken bone block is filled up die cavity
Module indentation die cavity is in contact to two position limiting structures can be obtained the thickness of plant bone mass, and there is no need to calculate filler quantity and pressure
Molded Depth degree, it is simple to operate, it is practical, and also the plant bone mass being pressed into has certain crushing resistance, can effectively support dimension
Hold intervertebral height, be not easy it is fragmentary, it is highly-safe, do carrier without fusion device and increase upper and lower soleplate circle between plant bone mass and centrum
The contact area in face is conducive to bone fusion, and considerably reduces surgery cost, alleviates the contradiction of patient's high cost of getting medical treatment.The vertebra
Between plant bone mass forming die structure it is simple, it is practical, can be widely applied to hospital Intervertebral disc fusion operation in.
Technical solution disclosed above exists following insufficient: die module is manual comprising fixed transverse rod and threaded
Pinch rod, pinch rod pass through fixed transverse rod threaded hole and pinch rod bottom compress upper module upper surface.Practical operation
In, since upper module needs to move up and down, when moving on upper module, the pinch rod for being pressed on the upper surface of upper module is also required to
It is mobile to move up space to discharge upper module, material is placed in the die cavity of lower module in order to convenient, upper module needs are raised
Enough height, such structure design needed when so that placing material and compression molding operation it is repeated multiple times rotatably compress bar, it is time-consuming
Arduously, hospital staff itself operating pressure is big, and thing is more cumbersome, is caused not using above-mentioned manual pressing mold mode to using
Just；Simultaneously as to watch whether position limiting structure chimb is in contact with pillar in real time, need to position post design in module one
Side, positioning column center and compression bar off(-)center are arranged, and influence when upper module is pushed along positioning column fluency in axial sliding, and
Due to the position limiting structure using chimb, a upper module can only extrude the bone block of a thickness, make troubles to using.
