Abstract
The utility model relates to a Y-shaped bone fracture plate for a finger bone or a toe bone. The bone fracture plate comprises a titanium alloy sheet formed by a vertical part and an upward fork part, wherein the vertical part is provided with N screw holes, the upward fork part is divided into two sides, and each side is provided with a screw hole; the fork part is of a V-shaped structure, the screw hole in one side of the upward fork part is a big hole, and the screw hole in the other side of the upward fork part is a small hole; the vertical part is arranged as an inwards bent concave cambered surface, the radius R is 4-10mm, and the vertical part is provided with the N screw holes; a concave-convex circular arc edge is arranged around the Y-shaped bone fracture plate, and the width L of a bone plate of the vertical part is 3.5-8mm. The Y-shaped bone fracture plate has the beneficial effects that the bone fracture plate can better fit with a bone surface, and damage to a periosteum is reduced; by the structure, the contact area between the bone fracture plate and the bone is reduced to some extent, the application scope is wide, and the universality is high.
Description
Technical field
This utility model relates to a kind of blade plate, especially a kind of Y shape blade plate for maniphalanx or toe bone.
Background technology
In daily life, the situation that can run into maniphalanx or get a broken toe unavoidably, causes serious inconvenience to our daily action.In blade plate, it is fixedly one of common method of fractures, the early stage hone lamella that is not specifically designed to maniphalanx or gets a broken toe, therefore normally used hone lamella is greater than the size of hand or foot, even the very little part fracture of a finger, also fix with very large hone lamella, make the even whole hands of whole finger all cannot be movable.Have a strong impact on daily daily life, and action time is easy to encounter hone lamella, fracture is wound again.
Now, along with the development of less invasive techniques and deepening continuously to fracture biological environment and union of fracture relation understanding.The settled principle of fracture, there is major transformation in fixing means, the fracture processing at finger or toe place starts to have adopted miniplate, but this blade plate surface is horizontal plane, for the maniphalanx that is arc for outer surface or toe bone, in use, its hone lamella will contact with surface of bone is local, after this can make screw fixing, hone lamella carries out the powerful extruding of centrality to surface of bone, surface of bone can not uniform stressed, cause local skeleton blood circulation infringement, union of fracture is also interfered, can blood fortune be produced and be destroyed in addition, when serious, also can produce a series of complication, such as postoperative interior fixing failure, delayed union, osteoporosis etc. under bone does not connect and hone lamella.Secondly, the miniature hone lamella using is at present all that a hone lamella can only be fixed on a surface of bone, can not fix by while nailing on multiple surfaces of bone, if fracture seriously need be in the time that multiple surface of bone nailings be fixing, conventionally adopt multiple hone lamellas to fix, this has also just strengthened the contact area of hone lamella and surface of bone to a certain extent, and its destruction to periosteum, bone fortune is also strengthened, and so still can cause healing cycle to extend.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of Y shape blade plate that is specifically designed to maniphalanx or toe bone, this Y shape blade plate can be fitted with bone better, avoid blade plate to carry out brute force extruding to periosteum, and fix applicable to boniness face, reduce again to a certain extent contacting of hone lamella and surface of bone, applied widely, versatility is large.
The purpose of this utility model is achieved in that a kind of Y shape blade plate for maniphalanx or toe bone, it is characterized in that: comprise by a vertical portion and a titanium-alloy thin-plate that fork upward forms, described vertical portion is provided with N screw hole, described fork is upward divided into both sides, and both sides are respectively provided with a screw hole.
Further, for the bending of Y shape blade plate energy is used, be applicable to the fixing of different surface of bone requirements, described fork is " V " shape structure, and one side screw hole is macropore, and opposite side screw hole is aperture.When use, be convenient to aperture curving and fix to carrying out screw on another surface of bone.
Further, better fit for the vertical portion and the surface of bone that make Y shape blade plate, make surface of bone evenly receive extruding, the described vertical portion spill cambered surface that is set to curve inwardly, its radius is R, which is provided with N screw hole.
Further, for making the spill cambered surface of vertical portion more fit maniphalanx or toe bone, the cambered surface radius of curvature R=4 ~ 10mm of described vertical portion.
Further, for make Y shape blade plate as far as possible with the prerequisite of surface of bone laminating under, reduce to the squish area of periosteum, avoid periosteum and bone fortune impaired, described Y shape blade plate periphery is provided with concavo-convex arc-shaped edges, the width L of its vertical portion hone lamella is 3.5 ~ 8mm.
The beneficial effects of the utility model are: 1,, because the vertical portion of Y shape blade plate is provided with aduncate spill cambered surface, which is provided with screw hole, therefore hone lamella and surface of bone can better be fitted, and surface of bone is evenly squeezed, and reduce the destruction to periosteum; 2, because of can bending to two plane carrying out screw and fix of fork thin plate, therefore reduced to a certain extent the contact area of hone lamella and bone, and it is fixing when fixing, can to select more suitably position to punch, applied widely, versatility is large.
