The utility model has the advantages that each component can be optionally disassembled, assembled and adjusted, can conduct the prolongation, the pressurization, the angle adjustment and the transverse displacement for fracture positions, and realizes the adjusting restoration of full position. Therefore, the utility model has the advantages of good suitability, wide application range, simple structure, convenient operation and use, simple preparation process and low cost.
Description
This utility model belongs to a kind of medical apparatus and instruments, the adjustable external immobilizer for fracture restitution of particularly a kind of combination type.
In the prior art, fixation of fractures generally can be divided into two classes, and a class is an internal fixation, and another kind of is external fixation.Internal fixation has steel plate and intramedullary needle etc.The steel plate internal fixation is bigger to soft tissue injury, needs two operations, and the patient's is painful big; The fixing pulp cavity inner membrance blood fortune of destroying of intramedullary needle is anti-ly revolved, bend resistance power is relatively poor, is unfavorable for union of fracture.External fixation has that clamping plate are fixed, plaster fixation and the external fixation etc. of threading a needle.Clamping plate are fixing fixing firm inadequately, tie up cumbersomely, and manageability influence soft tissue blood and transports, and the complication that causes is more; Plaster fixation is not firm, and influence closes on joint motion; The external fixation of threading a needle has the fixing and ring type of single arm type fixing etc.The fixing anti-axial force of single arm type is poor; Though ring type is fixed fixation, volume is bigger, and is not easy to operate, and heaviness is unfavorable for that the patient has a rest.
In order to overcome the problem that above-mentioned fracture fixing apparatus exists, I have invented " I-shaped machinery is adjusted fracture reduction fixator ", and the patent No. is " 87210403.6 ".It is mainly formed by holding pin adjustment rack, needle stand, pin folder, angle adjustment plate and adjustment arm etc.This holder has overcome the shortcoming of single arm type holder and ring type holder basically, but still there are the following problems, and 1, complex structure, the requirement on machining accuracy height, thereby cost of manufacture is higher; 2, can only be used on the long bone, can not arbitrarily dismantle combination according to the state of an illness, the use of privileged sites is subjected to certain restriction; 3, operate numerous rope, be difficult for grasping, need the doctor is carried out professional training; 4, volume is bigger, and heaviness influences the patient and has a rest.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, reduce the production cost of fracture fixing apparatus, provide a kind of and can arbitrarily dismantle combination, be convenient to operation and adjust, be fit to the adjustable external immobilizer for fracture restitution of the whole body fixed combination type of each position reduction of the fracture.
This utility model is achieved in that
This utility model has several to hold the pin adjustment rack, holds on the pin adjustment rack connecting plate is housed, and connecting plate and connecting rod join, be formed on the length and angle on all adjustable integral body, in addition fixed pin folder of the draw point of air exercise on bone is housed holding on the pin adjustment rack.
This utility model compared with prior art has following advantage:
1, each parts all can arbitrarily be dismantled combination, forms the holder that is fit to different parts, has both satisfied fixed requirement, have less profile again, thereby the suitability is good, not only can be used on the long bone, and the fracture of privileged sites also can be used, and range of application is wide.
2, hold between pin adjustment rack, connecting plate and the connecting rod and all can adjust, both extending, can shorten again, also can change angle, thereby, can prolong fracture site, pressurization, adjusting angle and transverse shift, realize the purpose that comprehensive adjustment resets.
3, volume is little, in light weight, helps the movable and rest of patient.
4, simple in structure, be easy to grasp, easy to operate and use; Processing technology is simple, low production cost.
