Detailed description of the invention
The type self-destroyed vertebral body shaper of one as shown in figures 1-4, include apparatus portion 1, apparatus portion 1 is connected with and implants rod 2, consider the facility of operation, apparatus portion 1 is provided with handle 8, its unusual part is: be provided with limit spring 23 in apparatus portion 1 of the present invention, and this apparatus portion 1 also includes inserts pipe 4.Specifically, for the ease of carrying out correct guiding, ensureing to implement smoothly, being connected with guide pipe 3 inserting on pipe 4, in this guide pipe 3, being provided with conduit 6.Simultaneously, insert in pipe 4 to be equipped with and insert bar 5, described conduit 6 is connected with self-destructor 7, described self-destructor 7 is connected with self-destruction bar 22, described self-destruction bar 22 one end is distributed with self-destruction block 24, and described conduit 6 inwall is provided with guide groove 11, and described self-destruction bar 22 is all installed in guide groove 11 with self-destruction block 24, be provided with limit spring 23 between self-destruction bar 22 and self-destruction block 24, form anti-contactinterval.Further, rely on the existence of limit spring 23, effectively can prevent self-destruction bar 22 from directly contacting with self-destruction block 24, there will not be false triggering.
With regard to the present invention one preferably embodiment, in order to realize effective self-destruction, and use procedure gathers and there will not be false triggering, and the self-destructor 7 of employing includes ratchet 12.Specifically, the ratchet 12 of employing is engaged with and advances ratchet 13 and crevis 16.Corresponding with it, be connected with back-moving spring 15 and main torsion spring 14 at propelling ratchet 13, and crevis 16 be connected with secondary torsion spring 17.Meanwhile, ratchet 12 is connected with propelling cover 21.Further, in order to and be convenient to realize stable transmission, propelling cover 21 is connected with drive link 18, drive link 18 is connected with driving lever 19, driving lever 19 is connected with time torsion spring 20.Moreover in order to realize effectively being threaded, meet the position adjustments needs that ratchet 12 advances cover 21, the present invention is provided with female thread at ratchet 12.Meanwhile, advance cover 21 to be provided with external screw thread, and female thread, external screw thread move towards distribution correspondence.
Like this, when reality uses, first take root in rod 2 by two and be placed into and insert in pipe 4, allow and insert bar 5 and enter and to insert in pipe 4 once, promote drive link 18 and drive driving lever 19.Afterwards, driving lever 19 drives and advances ratchet 13, advances ratchet 13 to drive that ratchet 12 is corresponding to turn an angle, and completes two and takes root in and insert into rod 2.Meanwhile, ratchet 12 also drives and advances cover 21 one-directional rotation certain angle, and self-destruction bar 22 declines certain distance.Then, exit and insert bar 5, drive link 18 resets by main torsion spring 14 and back-moving spring 15, secondary torsion spring 17, secondary torsion spring 20.Circulation like this, can complete and take root in inserting and realizing vertebral plasty of rod 2 more.
Further, in order to promote self-destruction effect, the head end of self-destruction bar 22 is provided with inclined-plane 25, and inclined-plane 25 contacts with self-destruction block 24, inclined-plane 25 is provided with main tooth 26, makes self-destruction block 24 also be provided with the secondary tooth 27 of corresponding engagement.Like this, when needs carry out self-destruction, self-destruction bar 22 constantly declines, the inclined-plane 25 of its head end first contacts with self-destruction block 24, the secondary tooth 27 that the main tooth 26 of self-destruction bar 22 is corresponding with self-destruction block 24 subsequently engages, self-destruction block 24 is pushed in conduit 6, and make drive link 18 not work on, namely this vertebral body shaper realizes self-destruction and cannot reuse.
Again further, for the ease of using, be convenient to vertebral plasty, the both sides, conduit 6 front end of employing are equipped with opening 9, and the head end of conduit 6 is provided with limiting plate 10.Meanwhile, in order to meet the location of guide pipe 3, carry out effective position adjustments, improve service precision, the rear end of guide pipe 3 is provided with spacing adjustment seat, spacing adjustment seat is connected with spacing adjustment seat described in adjustable pipe and is outside equipped with screw thread.Meanwhile, be provided with screw thread corresponding with it in adjustable pipe, spacing adjustment seat is threaded with adjustable pipe.Like this, when practical operation, the position of adjustment adjustable pipe can change the length of guide pipe 3, to control to insert the degree of depth that pipe 4 enters vertebral body.
Meanwhile, consider easy-to-use, carry out effectively correct implantation, the front end of implanting rod 2 is provided with plane 28, and the rear end of implanting rod 2 is distributed with tapered slope 29.Further, easy-to-use during in order to insert, what the present invention adopted insert bar 5 inserts bar 30 for tack, and tack is inserted bar 30 front end and is distributed with plane 28.Or consider different use needs, can also be insert bar 5 for conical head to insert bar 31, it be taper configurations 32 that conical head inserts bar 31 front end.
Can be found out by above-mentioned character express, after adopting the present invention, by apparatus portion and the cooperation of implanting rod, effectively carry out vertebral plasty.What is more important, have employed self-destructor and can prevent from reusing, and avoids pathophoresis possibility.Further, unitary construction of the present invention is simple, is easy to manufacture assembling and use, and is convenient to promote.
These embodiments are only the prominent examples of application technical solution of the present invention, allly take equivalent replacement or equivalent transformation and the technical scheme that formed, all drop within the scope of protection of present invention.
