Adjustable looped steel plate with tightened entrainment

Abstract

The invention relates to an adjustable looped steel plate with a tightened entrainment. The steel plate comprises an upper steel plate, a loop and an entrainment type tightening mechanism, wherein theentrainment type tightening mechanism is arranged on the upper steel plate, two ends of the loop are respectively connected with the entrainment type tightening mechanism after passing through the upper steel plate, and the loop adjusts the working length through the entrainment type tightening mechanism. The invention has the advantages that: An upper steel plate is arrange above that bone to berestored, An entrainment-type tighten mechanism is arranged on that side of the upper steel plate away from the bone to be restore, and the two ends of the loop are respectively connected with the clamping mechanism after passing through the bone to be restored and the upper steel plate, then the length of the loop in the bone to be restored is adjusted by the clamping tightening mechanism, As that length increase, the clamping force of the bone to be restore can be reduced at this time, and when the length decreases, the clamping force of the bone to be restore can be increased at this time,so as to facilitate finding a suitable force for restoring the bone to be restored and shortening the restoration time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable loop steel plate for entrainment and tightening. Background technique [0002] In dislocation treatment, how to perform reduction and fixation according to the bone structure is very important, which will directly affect the degree of recovery of the fracture site and become the key to the success of the operation. [0003] At present, when the patient's acromioclavicular joint dislocation needs to be reset and fixed clinically, most of them use two Endo button steel plates (button steel plates) to clamp the bones to be reset, and then use the loops to fix the two Endo button steel plates. However, there is a disadvantage when using this method for reduction and fixation, that is, once fixed, the clamping force cannot be adjusted. If the force is too large, the clamping will be tighter, and if the force is too small, the clamping It is relatively loose to h...

[0003] At present, when the patient's acromioclavicular joint dislocation needs to be reset and fixed clinically, most of them use two Endo button steel plates (button steel plates) to clamp the bones to be reset, and then use the loops to fix the two Endo button steel plates. However, there is a disadvantage when using this method for reduction and fixation, that is, once fixed, the clamping force cannot be adjusted. If the force is too large, the clamping will be tighter, and if the force is too small, the clamping Hold it loosely, but too loose or too tight will directly affect the degree of recovery of the fracture site
