Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being the control for measuring inside-fixture curvature in a kind of art
Plate.
Background technique
Backbone is the axial skeleton of human body, is the pillar of body, there is the functions such as weight bearing, damping, protection and movement.Backbone hand
In art usually with inside-fixture (titanium plate, stud) when the shape of inside-fixture can be adjusted, according to the backbone of sufferer
Radian changes the radian of inside-fixture so that the two matches.Need measuring tool to arc when adjusting inside-fixture curvature in operation
Degree measures.
However, about the inside-fixture in spinal operation in the prior art, the following defects and deficiencies exist:
Firstly, the inside-fixture used in backbone section does not measure the tool of radian targetedly in the prior art, it is clinical
Medical worker is usually to be bent according to clinical experience, and the radian of inside-fixture is only capable of rough estimate, cannot accurately measure song
It spends and meets clinical demand.
Secondly, the radian of the inside-fixture needed will carry out fining and just meet human body life because of human physiological structure's characteristic
Curvature, such as one piece of titanium plate are managed, needs to be divided into several parts in titanium plate, and the radian of each part needs difference, it is each to titanium plate
Partial radian is quantified just meet the requirements.And the prior art measures Arc Length Tool without quantization is carried out.
