Description
Technical field
This utility model relates to a kind of external fixation pressurization holder.
Background technology
Fracture is meant a kind of disease that causes sclerotin partially or completely to rupture owing to reasons such as wound or pathology.Its main clinical manifestation is: fractures has limitation pain and tenderness, local swelling and ecchymosis occurs, and limb function is partially or completely lost.At present in fracture operation, it mainly is to finish by fracture fixing apparatus that fracture site is positioned, fracture fixing apparatus mainly divides two kinds of inner fixer and external fixators, inner fixer mainly is in skin and flesh inside fracture site to be fixed, the skeleton typing effect of inner fixer is better, but need behind the bone healing inner fixer is taken out in patient's skin and flesh, caused unnecessary misery to the patient.And traditional external fixator is fixed with fixing head exactly except plaster fixation, because there is skin and flesh isolation fixed effect relatively poor, the typing effect is relatively poor, occurs abnormal phenomenon behind the bone healing easily.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to operate at above-mentioned deficiency, and the effective a kind of external fixation pressurization holder of finalizing the design.
For solving the problems of the technologies described above, this external fixation pressurization holder comprises upper mounted plate and bottom plate, upper mounted plate and bottom plate are provided with the nail hole, its construction features is: the upper mounted plate bottom is installed with buttcover plate, bottom plate top is installed with down buttcover plate, is provided with between last buttcover plate and the following buttcover plate to adjust the positioning and locking device of going up buttcover plate and following buttcover plate gap length.
The external fixation pressurization holder of this structure is realized finalizing the design effective by the pressurization fixed structure.The pressurization fixed structure comprises the last buttcover plate that is arranged on the upper mounted plate bottom, the last buttcover plate that is installed in bottom plate top, and be arranged on positioning and locking device between buttcover plate and the following buttcover plate, the function of buttcover plate and following buttcover plate on the existing location of positioning and locking device, there is locking to go up the effect of buttcover plate and following buttcover plate after the location again, after last buttcover plate and the following buttcover plate positioning and locking, upper mounted plate and bottom plate have so just been finished the location work of fracture also with regard to positioning and locking.During use, earlier upper mounted plate and bottom plate are positioned at two sections skeleton skin and flesh of fracture respectively, regulate the spacing that goes up between buttcover plate and the following buttcover plate by positioning and locking device then, the skeleton that fracture takes place and the preceding length of not fracturing are consistent, then positioning and locking device locking is lived, be to have coupling mechanism force between upper mounted plate and the bottom plate, the skeleton of fracture takes place so just at upper mounted plate, the combined effect of bottom plate and positioning and locking device keeps the location down, the typing effect is better, can make the fracture site healing in a short time, reduce patient's the pain of injury.
As a kind of implementation, described positioning and locking device comprises the slide bar that is installed on the buttcover plate, be installed with the sliding sleeve of suit slide bar on the following buttcover plate, be bolted with on the following buttcover plate and make buttcover plate and the isolating supporting studs of following buttcover plate, last buttcover plate and following buttcover plate are locked together by clamping screw.
In the positioning and locking device of this structure, slide bar can endwisely slip along slide bar in sliding sleeve, has so just played the effect of buttcover plate and following buttcover plate spacing on the orientation adjustment; The effect of following buttcover plate upper support double-screw bolt is to support to go up buttcover plate and following buttcover plate, by adjusting the length of supporting studs between last buttcover plate and following buttcover plate, can determine the minimum spacing between upper mounted plate and bottom plate; The effect that is arranged on the clamping screw on buttcover plate and the following buttcover plate is that last buttcover plate and following buttcover plate are locked, because the support of slide bar and supporting studs is arranged, so when adjusting supporting studs, again clamping screw is locked, upper mounted plate and bottom plate just have been positioned at together like this, and be very convenient.
As improvement, the supporting studs end is provided with ejector pin, and last buttcover plate is provided with the pin-and-hole that is slidingly matched with ejector pin.
For the structure that makes this external fixation pressurization holder more stable, end in supporting studs is provided with ejector pin, last buttcover plate is provided with the pin-and-hole that is slidingly matched with ejector pin, the end of supporting studs is inserted in the pin-and-hole, not only can prevent to skid when supporting studs end and last buttcover plate from compressing, and can alleviate the rock deformation pressure of slide bar, when clamping screw is locked, cooperation between slide bar, supporting studs and the clamping screw is tightr, and stability is stronger.
As a kind of embodiment, the cross section of slide bar is triangle or tetragon.
The Cross-section Design triangularity or the tetragon of slide bar can be prevented that slide bar from rotating in sliding sleeve, strengthened the structural stability of this external fixation pressurization holder.
In sum, adopt the external fixation pressurization holder of this structure, simple in structure, easy to operate, and it is effective to finalize the design, and uses when being applicable to external fixation of fracture, helps to improve success rate of operation.
