Abstract
The utility model discloses an intervertebral fusion cage, which comprises an upper supporting section, a lower supporting section and a cylindrical middle section connecting the upper supporting section and the lower supporting section. A left-right communicated filling hole and a back-fore communicated exchanging hole are arranged on the middle section, and the upper supporting section is conical. The design of the intervertebral fusion cage conforms to an intervertebral space anatomic curve and a lumbar vertebra physiological curve of a human body due to the conical upper supporting section, and facilitates normal movement for recovering a vertebral column.
Description
Technical field
This utility model relates to a kind of fusion device, particularly a kind of Invasive lumbar fusion device of anatomical form.
Background technology
Merging between the capable way of escape lumbar vertebra of employing Invasive lumbar fusion device is one of basic fundamental of spinal surgery, popularizes at home.Fusion device is as the core of waist interbody fusion, not only to provide good carrier for the bone grafting thing, effectively strut intervertebral space, avoid the bone grafting slippage, and should have good biomechanics characteristic and histocompatibility, so that can guarantee bone-graft fusion to greatest extent, therefore, its development and application come into one's own day by day.
Chinese patent ZL200420081725.X discloses " the oblique implanted Invasive lumbar fusion device of a kind of lumbar vertebral posterior ", and this fusion device is hollow hexahedron, divides back and front supporting section and therebetween thread segment three parts.Preceding supporting section (1) height greater than back supporting section (3) highly can recover lumbar vertebra physiology lordosis; The terminal plate of vertebral body that contacts with the back and front supporting section needn't destroy, and can prevent the sedimentation of fusion device; The slightly curved evagination of the upper and lower surface of thread segment (2) can firmly be embedded in the vertebral body, and each face is equipped with big small sircle hole, is convenient to bone piece and vertebral body and surrounding tissue fusion in the fusion device.Though the more existing fusion device of this fusion device has bigger improvement, also has the following disadvantages: 1, the supporting section upper and lower surface that contacts with terminal plate of vertebral body in front and back is the plane, is not the physiological curve shape that meets very much intervertebral; 2, the set small sircle hole of each face is more up and down, influences the firm degree of fusion device.
The utility model content
The purpose of this utility model is the above-mentioned defective that solves existing fusion device, provides a kind of external form more to meet the Invasive lumbar fusion device of dissection of human body intervertebral space and lumbar vertebra physiological curve.
The technical scheme that realizes this utility model purpose is: a kind of Invasive lumbar fusion device comprises the interlude of upper support section, lower support section and the column that is connected the two; The exchange hole that filler opening that connects about interlude is provided with and front and back connect; Described upper support section is conical.
Described lower support section is provided with screw from bottom centre to the interlude direction; The middle part of the two sides, front and back of lower support section is respectively equipped with groove.
Two sides are provided with jagged projection about described interlude.
After having adopted technique scheme, the utlity model has following positive effect: (1) upper support section of the present utility model is for conical, and this design meets the human body intervertebral space dissects and the lumbar vertebra physiological curve, helps replying the proper motion of spinal column.
(2) be provided with the screw of the implantation usefulness that cooperates with instrument and be convenient to tweezers class instrument and add the groove of holding on the lower support section of the present utility model simultaneously, made things convenient for the clamping of fusion device like this.
(3) serration that is provided with on the interlude of the present utility model increases fusion device and interpyramidal friction, avoids taking place after surgery problems such as slippage, and convenient when implanting.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, this utility model is described in further detail, wherein below
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Label is in the accompanying drawing:
Upper support section 1, lower support section 2, screw 21, groove 22, interlude 3, filler opening 31, exchange hole 32, projection 33.
The specific embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the Invasive lumbar fusion device of present embodiment comprises the interlude 3 of upper support section 1, lower support section 2 and the column that is connected the two.The exchange hole 32 that filler opening 31 that connects about interlude 3 is provided with and front and back connect, being provided with of these holes is beneficial to growing into of osteocyte and entering of body fluid and nutrient substance, is convenient to the fusion of postoperative bone.Upper support section 1 is conical.Lower support section 2 is provided with screw 21 from bottom centre to interlude 3 directions; The middle part of the two sides, front and back of lower support section 2 is respectively equipped with groove 21.Two sides are provided with jagged projection 33 about interlude 3.
Should be appreciated that specific embodiment described above only is used to explain this utility model, and be not used in qualification this utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
Claims (3)
1. Invasive lumbar fusion device comprises the interlude (3) of upper support section (1), lower support section (2) and the column that is connected the two; The exchange hole (32) that filler opening (31) that connects about interlude (3) is provided with and front and back connect; It is characterized in that: described upper support section (1) is for conical.
2. Invasive lumbar fusion device according to claim 1 is characterized in that: described lower support section (2) is provided with screw (21) from bottom centre to interlude (3) direction; The middle part of the two sides, front and back of lower support section (2) is respectively equipped with groove (21).
