Abstract
The utility model relates to a fast-connecting external mounting bracket, comprising a plurality of forceps holders, which is characterized in that: each forceps holder is provided with a pull screw, the forceps holder is connected with a connecting link via a multi-axial connector. The fast-connecting external mounting bracket has the advantages that: the tines of the forceps holders contact but do not penetrate through medullary cavity, so the medullary cavity is hermetic closure and infection is reduced; the fast-connecting external mounting bracket is of portability and firmness which is convenient to carry.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, applied fast-assembling external fixer in particularly a kind of bones of limbs reefing.
Background technology
In existing extremity fracture external fixer, of a great variety, but external fixer commonly used all has a common shortcoming, be exactly that locking pin must penetrate cortical bone and enters pulp cavity, cause pulp cavity to communicate with the external world, open fracture or war wound fracture are normal to be merged serious soft tissue injury and obvious pollution is arranged, and threading a needle to fix to increase infection chance.Also there are many defectives in existing AO/ASIF clamp type needleless external fixer: as needs than the complex installation apparatus, Eriocheir sinensis foot sample clamp chucking power deficiency, nut pressure locking hold deficiency is installed complexity etc.At present, lack the external fixation device of simplifying that can adapt to a line and basic unit's rescue.
Summary of the invention
The purpose of this utility model be to provide a kind of have volume little, in light weight, fixing definite, be convenient to install with after the external fixer of advantage such as send; This quick external fixer clamp tip is contact bone cortex shallow-layer and do not penetrate pulp cavity only, and pulp cavity still is in sealing state, and the infection that may occur also only is confined to soft tissue.This quick external fixer operating process simple possible, combined and instant by short-term cultivation or illustrate, just can be used installation; External fixer is light, aseptic waterproofing packing, be easy to carry, the wounded may lack basic surgical apparatus and strengthen under the image documentation equipment situation as electricity, pneumatic drill, X line in batches when the state of war or large-scale calamitous injury, also applicable more simplification, lighter, more economical, firmer, the external fixer that do not need extra installing apparatus.
A kind of fast-assembling external fixer described in the utility model, it comprises clamp, it is characterized in that: be provided with the pulling force screw rod on clamp, several clamps are connected with connecting rod by joint coupling.
The scheme one that this utility model is selected for use: clamp is an X-shaped, and the pulling force screw rod is located at the top of X-shaped clamp.
The scheme two that this utility model is selected for use: clamp is inverted U-shaped, and the pulling force screw rod is located at the arm of inverted U-shaped clamp.
Connecting rod described in the utility model can be single pole or two bar, is connected by joint coupling between two bars; Connecting rod is solid cylindricality or hollow cylindrical; The connecting rod surface is smooth circle, annular knurl circle, polygon, polygon prismatic.。
The tip of clamp described in the utility model can be made as unicuspid type, bicuspid, tricuspid type, four paws type.
The arm of clamp described in the utility model can be made as cylindrical, square, prismatic, quincunx.
On the pulling force screw rod described in the utility model screw nut can be made as butterfly-like T shape or the wheel dish type.
Nut on the joint coupling described in the utility model is butterfly-like or T shape or wheel dish type.
This utility model is established a vertical rod on clamp, be used for fixing joint coupling.
Joint coupling described in the utility model can be located at the arm or the pulling force screw rod place of clamp.
The beneficial effects of the utility model are, this fast-assembling external fixer clamp tip is contact bone cortex shallow-layer and do not penetrate pulp cavity only, and pulp cavity still is in sealing state, can reduce infection.And light firm, be convenient for carrying.
