Abstract
The invention discloses a titanium-mesh interbody fusion cage for minimally invasive surgery. The titanium-mesh interbody fusion cage comprises a cylinder made of titanium alloy material and is characterized in that an axial cavity is arranged in the cylinder and a plurality of through holes penetrating the outer wall of the cylinder are arranged on the cylinder. The through holes are arranged into a mesh-shaped structure. A plurality of protrusions with threads are arranged on the upper portion or the lower portion of the inner wall of the cylinder. End covers with gaps are disposed on the upper portion and the lower portion of the cavity respectively. The through holes arranged into a mesh-shaped structure are arranged on the outer wall of the cylinder and the protrusions with threads are arranged on the inner wall of the cylinder, and accordingly fixation is firm, complications such as instability of lumbar and iatrogenic spinal stenosis are avoided, and smooth recovery of a patient is guaranteed. In addition, the cylinder is made of titanium alloy material which is fine in fracture resistance and pressure resistance, is nontoxic and harmless for human bodies, and causes no adverse effects.
Description
Technical field
The invention belongs to medical instruments field, specifically, relate to a kind of Minimally Invasive Surgery with titanium net formula threaded fusion cage.
Background technology
The fracture Minimally Invasive Surgery uses microscope or high magnified glass, amplifies surgical field of view and carries out operation technique, implements " keyhole operation " by as far as possible little skin incision, makes the orthopaedics surgical operation implement the most effectively treatment with the iatrogenic injury of minimum.The lumbar vertebra diseases such as lumbar vertebra fracture, hyperosteogeny, intervertebral disk hernia are very common clinically.Above-mentioned disease can cause the spinal nerve pressurized and cause lumbago and skelalgia, or even disability, at present, the most effective Therapeutic Method is to cut from posterior lumbar spinal surgery, loosen by the nerve of card pressure, excision pathological interspinal dish, thereafter take from body adnexa osseous tissue and transplant in intervertebral, and be fixed rigid the fixing such as excellent, in the hope of up and down bony union between two vertebral bodys.But threaded fusion cage commonly used is easy to come off at present, causes the complication such as lumbar instability, iatrogenic spinal canal stenosis, serious threat patient's health.Simultaneously, the material of existing threaded fusion cage is softer, can't satisfy the needs to fusion device hardness.
Summary of the invention
The technical problem to be solved in the present invention is to overcome defects, provide a kind of simple in structure, be not easy to come off and Minimally Invasive Surgery that hardness is high with titanium net formula threaded fusion cage.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of Minimally Invasive Surgery comprises cylinder with titanium net formula threaded fusion cage, it is characterized in that: be provided with axial cavity in the described cylinder, be provided with some through holes on the described cylinder, through hole runs through cylindrical outer wall.
Say further:
Through hole on the described cylinder is mesh and arranges.
Described through hole assumes diamond in shape, and runs through cylinder.
Described through hole ovalize shape, and run through cylinder.
Further say:
Described cylinder is made by titanium alloy material.
Further say:
Be provided with some screwed projections on the described cylindrical medial surface.
The described cylindrical shape that raises into is provided with screw thread on the end face of projection.
Further say:
Described projection is arranged on the top of cylinder interior face or/and the bottom.
Further say:
The upper and lower of described cavity is provided with respectively the end cap in space.
Owing to having adopted technique scheme, compared with prior art, the present invention is cylindrical, the centre is provided with axial cavity, be provided with the through hole that is the mesh arrangement at outer wall, and be provided with screwed projection on the inwall, such design, guaranteed fixing firmly to have avoided the appearance of the complication such as lumbar instability, iatrogenic spinal canal stenosis, guaranteed patient's smooth rehabilitation, simultaneously, cylinder of the present invention is made by titanium alloy material, has good anti-folding and anti-pressing performance, has no adverse reaction to human body is nontoxic.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1.
Among the figure: the 1-through hole; The 2-cylinder; The 3-end cap; The 4-projection.
The specific embodiment
Embodiment:
As described in Fig. 1, Fig. 2, Fig. 3, a kind of Minimally Invasive Surgery comprises cylinder 2 with titanium net formula threaded fusion cage, is provided with axial cavity in the cylinder 2, is provided with some through holes 1 on the described cylinder 2, and through hole 1 runs through the outer wall of cylinder 2.In the present embodiment, described through hole assumes diamond in shape, and runs through cylinder.Perhaps through hole ovalize shape, and run through cylinder.
In the present embodiment, the through hole 1 on the cylinder 2 is the mesh arrangement.Described cylinder is made by titanium alloy material.Be provided with some screwed protruding 4 on the described cylindrical medial surface.Described protruding 4 are arranged on top or the bottom of cylinder interior face, and raise into cylindrical shape, are provided with screw thread on the end face of projection.
Also have a kind of situation, projection is arranged on the upper and lower of cylinder interior face exactly.The upper and lower of described cavity is provided with respectively the end cap in space.
Shell of the present invention is cylinder, and the centre is provided with axial cavity.Shell is that cylinder is a kind of most preferred embodiment, so shell is other shapes, also in protection scope of the present invention.Be provided with the through hole that is the mesh arrangement at outer wall, and be provided with screwed projection on the inwall, such design, guaranteed fixing firmly to have avoided the appearance of the complication such as lumbar instability, iatrogenic spinal canal stenosis, guaranteed patient's smooth rehabilitation, simultaneously, cylinder of the present invention is made by titanium alloy material, has good anti-folding and anti-pressing performance, has no adverse reaction to human body is nontoxic.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
