Detailed description of the invention
The anti-displacement bulk expansion of one as shown in figures 1-4 formula inter vertebral fusing device, include and insert apparatus 2, insert on apparatus 2 and be connected with fusion device 1, its unusual part is: fusion device of the present invention includes deformation shell 3, is connected with interior swingle 4 in deformation shell 3.Meanwhile, insert apparatus 2 and include outer control valve 14, in outer control valve 14, be provided with inner connection tube 15.Further, the afterbody of deformation shell 3 is connected with one end of inside connecting rod 15, and inner connection tube 15 other end is provided with platform 29, prevents outer control valve 14 from throwing off with deformation shell 3.Inner connection tube 15 is built with driving handle 16.Certainly, consider that the assurance of user is convenient, driving handle 16 tail end is connected with handle 21.
With regard to the present invention one preferably embodiment, for the ease of opening smoothly in use procedure, before deformation shell 3 includes, strut portion 5.Meanwhile, the front portion 5 that struts is connected with rear deformations 7 by middle part link 6.Specifically, strut the generation after interior swingle 4 rotates of portion 5, middle part link 6 and rear deformations 7 before considering and expand in various degree, thus larger contact area is provided and forms good support.Strut portion 5 before adopting and be provided with upper surface 9 and lower surface 10, middle part link 6 is provided with chute.Thus, upper surface 9 that when deformation shell 3 expands, it contacts with vertebral body is convenient to and deformation occurs in lower surface 10.In other words, upper surface 9 and lower surface 10 entirety strut and form front protrusion 22 and the rearward projection 23 of anti-displacement, and the arcwall face meeting the lower soleplate 27 of vertebral body and upper soleplate 28 forms good contact and spacing.
Further, deformation shell 3 afterbody 8 of employing is provided with groove 11.Corresponding with it, the front end of outer control valve 14 is provided with main boss 18.Like this, when deformation shell 3 contacts with outer control valve 14, groove 11 is connected with main boss 18, in case rotate during fusion device 1 dilating expansion.Meanwhile, effectively connecting effect to promote, being distributed with female thread 19 hole 12 in groove 11, inner connection tube 15 front end is provided with corresponding screw thread 19, and the rear end of inner connection tube 15 is provided with platform 29.Thus, can be connected inserting apparatus 2 with fusion device 1, realizing effective thread 19 and connecting.
Again further, the tail end of interior swingle 4 is provided with interior hexagonal hole 13, and the front end of driving handle 16 is hexagon front end 20, and the front end of driving handle 16 can be inserted in the interior hexagonal hole 13 of interior swingle 4 tail end.Meanwhile, strut top, portion 5 and be provided with secondary boss 24 before deformation shell 3, interior swingle 4 side arranges the plane contacted with secondary boss 24.Thus, prevent the Invasive lumbar fusion device 1 after expanding from bouncing back again.Certainly, in order to promote being located by connecting and expansion effect of internal swingle 4, in rectangle, swingle 4 front end is provided with little groove 25.Like this, when fusion device 1 does not strut, the front secondary boss 24 strutting top, portion 5 is positioned at the little groove 25 of rectangle swingle 4 front end, to reduce the volume before fusion device 1 expansion as far as possible.Further, after interior swingle 4 rotates, the front secondary boss 24 strutting top, portion 5 is positioned on the side plane 26 of rectangle swingle 4, farthest struts to strut portion 5 before ensureing deformation shell 3.Meanwhile, interior swingle 4 cross section is rectangle, guarantees latter linked stablizing effectively of expanding.
Meanwhile, consider the position that effectively can adjust outer control valve 14, to utilize service aisle spacing in endoscopic surgery, when ensureing that fusion device 1 is inserted, accurately control implantation site.Be distributed with screw thread 19 outside outer control stick 14, in spacing shelves pipe 17, be distributed with corresponding screw thread 19.
Can be found out by above-mentioned character express, after adopting the present invention, strut portion, middle part link and rear deformations before this Invasive lumbar fusion device deformation shell to occur to expand in various degree after inward turning bar rotation, realize forming good contact with the lower soleplate of vertebral body and the arcwall face of upper soleplate and spacing.Like this, larger contact area and good support can be provided to reduce and to sink, can prevent again fusion device from occurring displacement, increase stability and the reliability of this fusion device.Moreover simple structure of the present invention, can be widely used in multiple spinal fusion surgery.
Certainly, above is only embody rule example of the present invention, does not constitute any limitation protection scope of the present invention.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
