Description
Technical field
This utility model belongs to technical field of medical instruments, and particularly, this utility model relates to a kind of metaphysis compression fixator.
Background technology
Setting board of skeleton end fracture is often caused by stronger violence, normal with comminuted fracture, serious soft tissue injury, and fracture is close or involve articular surface, Clinical Processing is more difficult, easy generation soft tissue necrosis, infection of bone, exposed bone etc., bring a lot of difficulty to clinical treatment, and therefore the selection of fixing means is the key determining prognosis.Its fixed form has multiple, comprises exterior fixation bracket, traditional open reduction and Kirschner wire fixation, micro wound coaptation plate and interlocking intramedullary nail etc.The use of exterior fixation bracket easily leads to complications, as pin track infection, support loosen and malunion of fracture etc.Many problems are faced in art when interlocking intramedullary nail is used for fixing setting board of skeleton end fracture, comprise reduction of the fracture difficulty, the stress that distal locking nail too closely causes apart from fracture end is concentrated, and distal bone folded block is fixed not firm and may be occurred that complicated intra-articular fracture needs open reduction to treat.
Therefore, a kind of metaphysis fixture that can overcome above-mentioned shortcoming of research design is needed badly.
Utility model content
The purpose of this utility model is, provides a kind of metaphysis compression fixator, and this compression fixator one end does not use screw to be fixed, the more useful healing with fracture portions, and, be convenient to when taking out take out.
For achieving the above object, this utility model have employed following technical scheme:
A kind of metaphysis compression fixator, described compression fixator comprises the first fixed part 1 and the second fixed part 3 and the connecting portion 2 for being connected the first fixed part 1 and the second fixed part 3;
Described first fixed part 1 is several bars 4, and this bar 4 is fixed for passing metaphyseal fracture portions (knochenbruch) and inserting in backbone;
The shape of described connecting portion 2 is the arc-shaped flaky fitting in bone surface;
Described second fixed part 3 arranges some pressurization fixing holes 5, and described second fixed part 3 is fixed on the backbone that is connected with metaphysis by forcing screw through pressurization fixing hole 5;
The position that described connecting portion 2 connects with the first fixed part 1 arranges a notched circular hole 8, and this circular hole 8 is convenient to the taking-up of guide pin.
As an optimal technical scheme of the present utility model, the end of described bar 4 arranges groove 6, and the degree of depth of groove shoals along bar from the centre of groove gradually to both ends, when this bar 4 is inserted in bone, this groove 6 fits in Kirschner wire, is convenient to bar 4 and inserts in bone and the taking-up of Kirschner wire.
Preferably, the shape of described bar 4 is conical.The shape that those skilled in the art can also select other suitable as required.
Preferably, the number of described bar 4 is two.The number that those skilled in the art can also select other suitable according to the size of knochenbruch position or knochenbruch.
As another optimal technical scheme of the present utility model, described pressurization fixing hole 5 adds pressure slope 7 along establishing in the week of hole.Still more preferably, adding pressure slope 7 described in centerline hole is 45-60 ° of angle.
In this utility model, the making material of described compression fixator is titanium alloy.What those skilled in the art can also select other to be applicable to as required prepares material, such as can by the material of bone resorption.
Concrete using method of the present utility model is: first resetted by knochenbruch, knochenbruch is looked for suitable some punching position, punch on knochenbruch according to the spacing of two bars on the compression fixator that will use and length in the both sides of locating hole again and adopt Kirschner wire to be fixed, then the groove of bar end being close to Kirschner wire and inserting in the hole.After fixing, directly the second fixed part can be close on backbone, and adopt forcing screw to be fixed.In fixing process, the second fixed part tractive first fixed part, because the bar of the first fixed part has inserted in bone, therefore, in the process of tractive, compression fixator is close to metaphysis and on the backbone that is connected with metaphysis, thus is fixed knochenbruch.
This utility model is compared to prior art, and its advantage is: compression fixator one end of the present utility model does not use screw to be fixed, the more useful healing with fracture portions, and, be convenient to when taking out take out.

Detailed description of the invention
With the drawings and specific embodiments, this utility model is described in further detail below.
Embodiment 1
As shown in Figure 1, a kind of metaphysis compression fixator, described compression fixator comprises the first fixed part 1 and the second fixed part 3 and the connecting portion 2 for being connected the first fixed part 1 and the second fixed part 3;
Described first fixed part 1 is two conical bars 4, and this bar 4 is fixed for passing metaphyseal fracture portions and inserting in backbone;
The shape of described connecting portion 2 is the arc-shaped flaky fitting in bone surface;
Described second fixed part 3 arranges some pressurization fixing holes 5, and described second fixed part 3 is fixed on the backbone that is connected with metaphysis by forcing screw through pressurization fixing hole 5;
The position that described connecting portion 2 connects with the first fixed part 1 arranges a notched circular hole 8, and this circular hole 8 is convenient to the taking-up of guide pin.
As shown in Figure 2, the end of described bar 4 arranges groove 6, and the degree of depth of groove shoals along bar from the centre of groove gradually to both ends, when being inserted in bone by this bar 4, this groove 6 fits in Kirschner wire, is convenient to bar 4 and inserts in bone and the taking-up of Kirschner wire.
As shown in Figure 3, described pressurization fixing hole 5 adds pressure slope 7 along establishing in the week of hole.It is described that to add pressure slope 7 with centerline hole be 60 ° of angles.
In this utility model, the making material of described compression fixator is titanium alloy.
As shown in Figure 4, concrete using method of the present utility model is: first resetted by knochenbruch 10, knochenbruch 10 is looked for suitable some punching position, punch in the both sides of locating hole on knochenbruch 10 according to the spacing of two bars 4 on the compression fixator that will use and length and adopt Kirschner wire to be fixed again, then the groove 6 of bar 4 end being close to Kirschner wire and inserting in the hole.After fixing, directly the second fixed part 3 can be close on key 9, and adopt forcing screw to be fixed.In fixing process, the second fixed part 3 tractive first fixed part 1, because the bar 4 of the first fixed part 1 has inserted in bone, therefore, in the process of tractive, compression fixator is close to metaphysis and on the backbone that is connected with metaphysis, thus is fixed knochenbruch 10.
