Abstract
The invention discloses a minimally invasive spine inner fixing system used for assisting spine shape correction. The system consists of press rings and draw hooks, wherein the press rings and the draw hooks are of an integral structure; when the press ring quantity is one or more, the two draw hooks are respectively positioned at two ends of the press rings, and a plane in which the press rings are located is vertical to a plane in which the draw hooks are located; when the press ring quantity is one, the two draw hooks are respectively positioned at two ends of the press ring, and the openings of the two draw hooks are opposite to each other; when the press ring quantity is two, the two draw hooks are respectively positioned at the outside ends of the two press rings, and the openings of the two draw hooks are opposite to each other; when the press ring quantity is three, the two draw hooks are respectively positioned at the outside ends of the two press rings positioned at two ends, and the openings of the two draw hooks are opposite to each other. The minimally invasive spine inner fixing system disclosed by the invention has the advantages of convenience and rapidness in operation, less operative wound, and convenience for withdrawing of instruments in the late stage.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of minimally invasive spine internal fixation system for auxiliary backbone correcting.
Background technology
For stiff Patients Undergoing Scoliosis Correction, it is orthopedic that the interior all pedicle screws technology of main employing sections is carried out three-dimensional at present, although surgical effect has obtained raising, if but adopt stiff titanium rod,, easily there are some complication in the addendum cone region severe scoliosis patient, as being difficult to that stiff titanium rod is connected with pedicle nail, stress concentration, pedicle nail is extracted etc.On the other hand, niti-shaped memorial alloy is when temperature drops to specific critical temperature, comparatively soft, can random-shaping, and after temperature is heated to over critical temperature again, can natural reinstatement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenient to operation, operation wound is little, later stage apparatus is convenient to remove minimally invasive spine internal fixation system.
The present invention addresses the above problem adopted technical scheme: this system is comprised of pressure rings and the drag hook of integrative-structure, the quantity of pressure rings is one or more, two drag hooks lay respectively at the two ends of pressure rings, and the plane at the plane at pressure rings place and drag hook place is orthogonal.
Pressure rings quantity of the present invention is one, and two drag hooks lay respectively at the two ends of pressure rings, and the opening of two drag hooks is relative.
Pressure rings quantity of the present invention is two, and two drag hooks lay respectively at the outboard end of two pressure rings, and the opening of two drag hooks is relative.
Pressure rings quantity of the present invention is three, and two drag hooks lay respectively at two outboard ends that are positioned at the pressure rings at two ends, and the opening of two drag hooks is relative.
It is conical that the end of drag hook of the present invention is.
The present invention compared with prior art has following beneficial effect: this fixed system is made by a niti-shaped memorial alloy bending, comprise pressure rings and drag hook, niti-shaped memorial alloy has good super-elasticity, in certain deformation range, can maintain constant elasticity, and have good endurance, decay resistance, histocompatibility is fine, little to human toxicity, niti-shaped memorial alloy deliquescing after frozen water soaks, drag hook inserts respectively in two relatively loosening joint vertebra taper holes, pressure rings is attached to pars interarticularis place plane, after rewarming, Ultimum Ti can produce huge restoring force, vertebral body and vertebral plate are firmly fixed together, plant bone mass is pressed to isthmus simultaneously, pressurization that can be continual and steady to isthmus, it can increase along with the increase of mobility bed knife, do not need to fix separately, in clinical practice, there is operation wound little, convenient and swift, the advantages such as later stage apparatus is convenient to remove, in the associated biomolecule Experiments of Machanics of carrying out, show, isthmus split lumbar vertebra accept fixing after, it is respectively able to obvious recovery to stability, approach normal lumbar vertebra.

The specific embodiment
Embodiment 1:
Referring to Fig. 1, the present embodiment is made with a niti-shaped memorial alloy bending, a pressure rings 1 and two drag hooks 2 by integrative-structure form, and two drag hooks 2 lay respectively at the two ends of pressure rings 1, and the plane at the plane at pressure rings 1 place and drag hook 2 places is orthogonal; The opening of two drag hooks 2 is relative, and the end of drag hook 2 is conical.
Embodiment 2:
Referring to Fig. 2, the present embodiment is made with a niti-shaped memorial alloy bending, two each and every one pressure rings 1 and two drag hooks 2 by integrative-structure form, and two drag hooks 2 lay respectively at the outboard end of two pressure rings 1, and the plane at the plane at pressure rings 1 place and drag hook 2 places is orthogonal; The opening of two drag hooks 2 is relative, and the end of drag hook 2 is conical.
Embodiment 3:
Referring to Fig. 3, the present embodiment is made with a niti-shaped memorial alloy bending, three each and every one pressure rings 1 and two drag hooks 2 by integrative-structure form, and two drag hooks 2 lay respectively at two outboard ends that are positioned at the pressure rings 1 at two ends, and the plane at the plane at pressure rings 1 place and drag hook 2 places is orthogonal; The opening of two drag hooks 2 is relative, and the end of drag hook 2 is conical.
The present invention is as adopted two or more pressure rings 1, and the distance between each pressure rings 1 can be formulated as required.
When the present invention uses, first by its deliquescing after frozen water soaks, then by distraction forcep, pressure rings 1 is strutted, two drag hooks 2 insert respectively in two relatively loosening joint vertebra taper holes, and pressure rings 1 is attached to pars interarticularis place plane, with warm saline to its rewarming after, Ultimum Ti produces huge restoring force, pressure rings 1 is returned to original state, drives drag hook 2 that vertebral body and vertebral plate are firmly fixed together, and plant bone mass is pressed to isthmus simultaneously.
