The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
See also Fig. 1, the structural representation of the pressure bone bearing that Fig. 1 provides for the embodiment of the invention.
Wherein, 1 is matrix, and 2 for moving seat, and 3 is compact heap, and 4 is gathering sill, and 5 is pilot hole, and 6 is lead, and 7 is compression elastic piece, and 8 for pressing the bone piece.
The pressure bone bearing that is used for fixing fusion device that the embodiment of the invention provides comprises: be provided with the matrix 1 of hole slot and gathering sill 4, mobile seat 2, compact heap 3 and guide spring mechanism.
Wherein, guide spring mechanism specifically comprises lead 6 and compression elastic piece 7, the pilot hole 5 that setting and lead cooperate on the propulsive mechanism of matrix 1 or mobile seat 2.If pilot hole 5 is arranged on the matrix 1, then lead 6 one ends are fixed on the propulsive mechanism of described mobile seat 2, the other end inserts in the pilot hole on the described matrix 1; In like manner, if pilot hole 5 is arranged on the propulsive mechanism that moves seat 2, then lead 6 one ends are fixed on the described matrix 1, the other end inserts in the pilot hole on the described mobile seat 2.Be about to lead 6 one ends and fix, the other end has the degree of freedom that moves along pilot hole 5.Compression elastic piece 7 is sleeved on the lead 6 between described mobile seat 2 and the matrix 1.Wherein compression elastic piece 7 is preferably the compression spring.Because in advance the elastic force of setting is (promptly by selecting elastic component with appropriate elastic potential energy; reach the purpose of setting appropriate elastic force); so can play a good protective effect to implant, firmly add under the prerequisite of holding in assurance, can not damage implant because of chucking power is excessive.
Move seat 2 one ends and insert in the described gathering sill 4, and can move along gathering sill 4.Compact heap 3 is positioned at described hole slot 4, and is fixed on the described mobile seat 2.Promptly move to move seat at 2 o'clock, the inwall of the gathering sill 4 that compact heap 3 and this compact heap 3 are relative has formed adding of a size variation and has held fixed bin.
In sum, the present invention leads with lead 6, adopt compression elastic piece that controlled design thrust is provided, can form the storehouse that grips that is fit to different fusion devices by promoting to move seat 2, adding when holding fixed bin and being a bit larger tham fusion device, fusion device is put into fixed bin, loose one's grip then, fusion device is clamped 3 and adds and fasten.Pressure bone bearing provided by the invention can be realized quick, safe, stable fixedly fusion device.This mode of pushing, the doctor can singlehanded execution, and the another hands can be held other operations such as getting fusion device, raises the efficiency, and saves operating time, improves the bone grafting quality.In addition, because this device is set thrust in advance,, can not damage implant because of chucking power is excessive so can play a good protective effect to implant.
Further, in order to optimize technique scheme, compact heap 3 is provided with the fin that improves thrust with mobile seat 2 relative faces, and promptly the face that steps up of compact heap 3 is provided with fin.By fin is set, make that the contact surface of clamp 3 and fusion device is the combination of a plurality of little contact surfaces, step up to wear next flatness error thereby can reduce.
In like manner, matrix 1 and the relative face of fin on the compact heap be provided with described compact heap on the corresponding fin of fin.Promptly on the matrix 1 and compact heap 3 step up jointly also to be provided with fin on the face of fusion device.
The material of matrix 1 and compact heap 3 preferentially is chosen as macromolecular materials such as PPSU or POM.Avoided the damage that may cause in the process is tamped in the fusion device clamping.
Described propulsive mechanism is provided with presses bone piece 8, and on the described matrix and the corresponding position of the described first pressure bone piece also is provided with presses bone piece 8.For two pressure bone pieces are distinguished, the pressure bone piece that is arranged on the propulsive mechanism is called the first pressure bone piece, will be arranged on the matrix and the first second pressure bone piece that is called of pressing on the bone piece opposite position.It is macromolecular materials such as PPSU or POM that the first pressure bone piece and described second is pressed the material of bone piece.
The present invention presses the bone piece by being provided with, and uses the fixedly guide spring mechanism of fusion device, realizes compressing molding fusion device bone grafting fast, and bone grafting is tamped in fusion device bone grafting chamber closely, saves operating time, improves operation bone grafting quality.
See also Fig. 2, Fig. 3, the fusion device that Fig. 2 provides for the embodiment of the invention is pressed on the sketch map on the compact heap, and Fig. 3 is the vertical view of Fig. 2.
Wherein, 3 is compact heap, and 6 is lead, and 7 is compression elastic piece, and 9 is fusion device, and 10 hold fixed bin for adding, and 901 is the bone grafting chamber.
The main effect of pressure bone bearing provided by the invention is: compress fusion device 9 with compact heap 3, give 9 one reliable and stable supports of fusion device, make things convenient for the doctor to tamp broken bone grafting in fusion device 9 intermediary bone grafting chambeies 901.Because the present invention has adopted guide spring mechanism, make the adding of fusion device that can adapt to various models fasten, and step up power and stablize, can not cause damage to the fusion device surface.
See also Fig. 4, Fig. 5, the fusion device that Fig. 4 provides for the embodiment of the invention is pressed on the sketch map on the bone piece, and Fig. 5 is the vertical view of Fig. 4.
Wherein, 8 for pressing the bone piece, and 9 is fusion device.
The adjection of pressure bone bearing provided by the invention is: use to press bone piece 8, with the broken bone grafting of inserting in the fusion device 9 bone grafting chambeies, compacting fast, compress, molding.Step up pressing on the bone piece 8 in the bone grafting chamber that is about to fill up the fusion device 9 of broken bone grafting, by artificial impetus, fast with broken bone grafting compacting, compress, molding.Wherein, press the bone grafting chamber port shape of the profile of bone piece 8 and fusion device 9 identical, so realize to broken bone grafting quick compacting, compress, molding.
Each embodiment adopts the mode of going forward one by one to describe in this description, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
