Description
Technical field
This utility model belongs to orthopaedics fixed apparatus field, is specifically related to a kind of plug-in combination inner fixing device that is suitable for the orthopedic use of skeleton under the miscellaneous fracture state.
Background technology
At present domestic and international orthopaedics internal fixation implant is still based on steel plate, intramedullary pin series, along with updating of these two kinds of serial fixtures with perfect, existing various straight type pressing types and the anatomical plate researched and developed, various self-lockings and interlocking type intramedullary pin, various external fixers and memorial alloy series fixture, and advanced " AO " liss steel plate etc.In the face of of a great variety, specification, complex-shaped implant and supporting training equipment often bring trouble in the selection to clinical operation, deviation in the selection not only causes suffering to the patient, even the final effect of influence operation, severe patient may cause operative failure, causes medical tangle.With regard to the operation operation, the intramedullary pin operation needs to expand marrow, interlocking, more need skilled operating technology, in case interlocking is inaccurate in the art, operation will be difficult to carry out, and the steel plate series operation needs open reduction to fix, and need peel off periosteum, even the direct compression fractures of steel plate position, have a strong impact on the osteogenesis environment.In addition, also there is the problem of stress shielding and stress concentration jointly in steel plate intramedullary pin series; Though the operation of external fixator series has good randomness, often usually can not be as the termination fixture because of postoperative infection.The design people is once at the deficiencies in the prior art for this reason, treatment theory based on Wicresoft and biological internal fixation, designed and integrated the bridge connected combination bone fracture internal fixing device of steel plate, intramedullary pin and exterior fixation bracket fixture advantage aspect structure, the operating characteristics, obtained good effect, but adopt the pass mode to connect, exist contiguous block not allow easy-operating problem, be unfavorable for the operation of bridge joining composite inner fixing device enforcement Wicresoft.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and is convenient to be connected and fixed, and helps localized composite bone fracture internal fixation clamping apparatus.
The purpose of this utility model is achieved in that a fixing threaded hole is set on the clamping apparatus principal plane at least that perpendicular to the principal plane direction grab groove is set at least, described grab groove matches with pitman.
The clamping apparatus of this utility model is the grab groove of opening, make things convenient for locking nail, pitman to cooperate with the free each other winding of clamping apparatus, help forming stiff assembly fracture internal fixation framework, the fractured bones block reset is fixed into former physiology overall structure state, the improper stress that has overcome prior art generation itself causes adverse consequences to osteogenesis, improve the fixed effect that resets, enlarged the generation of indication scope and minimizing complication.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described, but never in any form this utility model is limited, any conversion based on this utility model training centre is done all falls into protection domain of the present utility model.
As shown in Figure 1 and Figure 2, this utility model comprises clamping apparatus and pitman 3, it is characterized in that: a fixing threaded hole 1 is set on the described clamping apparatus principal plane at least, perpendicular to the principal plane direction grab groove 2 is set at least, described grab groove 2 matches with pitman 3.
The inner face of the grab groove 2 on the described clamping apparatus is provided with annular knurl 6, and with the annular knurl 6 that is provided with on the work surface under locking nail 4 heads of a nail, and the annular knurl 6 on pitman 3 surfaces matches.Fig. 7 shows this utility model pole embodiment, and described pole surface is provided with annular knurl.Fig. 8 has gone out this utility model lock screw embodiment, and described locking nail is the two-stage nitration screw thread, and the threaded engagement of head of a nail screw thread and clamping apparatus screw is provided with annular knurl 6 under the head of a nail.
As shown in Figure 3,, be symmetrical in fixing threaded hole 1 on the described clamping apparatus grab groove 2 is set, and a fixing threaded hole 1 is set at least, be fit to be used with single pitman 3 and two locking nail 4 as this utility model diplopore list rod embodiment.
As Fig. 4, Fig. 5, Fig. 9, shown in Figure 10, as this utility model single hole double stick embodiment, at least one pair of grab groove 2 is set on the described clamping apparatus, be fit to doubly-linked take over the baton 3 and single locking nail 4 be used.
