Description

A kind of medical surgical multifunctional measuring chi

Affiliated technical field

The utility model relates to technical field of medical instruments, particularly relates to a kind of medical surgical multifunctional measuring chi.

Technical background

In the spinal surgery clinical practice, need to be directed against many spinal structures and to indicate the angle of the kinematic relation between them to carry out quantitative measurment, instruct the diagnosis and the treatment of disease through measurement data.Survey instrument at present commonly used, the operation more complicated and, precision is not high, has had a strong impact on to have arrived medical efficient and quality.Therefore being necessary to design a kind of angle of using always in backbone X line, CT, the MRI image data that can be directed against soon all can measure; Fast and convenient; The medical surgical multifunctional measuring chi that measuring accuracy is high; In order to help judging data such as physical location, size and length in the operation on vertebra treatment, so that instruct the treatment of operation on vertebra, this also is current facing of the task in this area.

Summary of the invention:

It is a kind of simple in structure that the purpose of the utility model is to provide, measure fast and convenient, the medical surgical multifunctional measuring chi that measuring accuracy is high.

In order to achieve the above object; The utility model adopts the technical scheme of following structure: a kind of medical surgical multifunctional measuring chi; Form by bottom plate 1, upper head plate 10, high scale dish 5, following index dial 2, outer pointer 4, interior pointer 3, bearing 7, rotating shaft 8, weight 9, damped ring 6 and screw 11; Its characteristics are: the central upper portion place of transparent bottom plate and upper head plate respectively has manhole with the level, and two manholes are corresponding, and netted coordinate line is carved with in the bottom of upper head plate outside surface; The corresponding coincidence of circular transparent index dial up and down stacks, and folds up the interior pointer of prolate strip up and down in the gap between the index dial movingly, and interior pointer one end connects the flat weight; Following index dial center is designed with the bearing counterbore, and there is bearing cross hole at the center of pointer in high scale disk center and the prolate strip; Transparent outer pointer round end center also has bearing cross hole; Bearing cross hole on high scale dish, interior pointer and the outer pointer overlaps mutually with the bearing counterbore on the following index dial; The ladder rotating shaft fitted bearing that has nut passes the bearing cross hole on outer pointer, high scale dish and the interior pointer successively; Be seated in down in the bearing counterbore on the index dial; The end plate up and down that overlaps is the integral body of rectangle with the screw riveted, constitutes medical surgical multifunctional measuring chi.

Scale graticule minimum division value on the above-mentioned said index dial up and down is 1 degree,

The distance between centers of tracks minimum value of the netted coordinate line of above-mentioned said upper head plate outside surface is 1 millimeter.

Interior pointer in the utility model freely rotates around rotating shaft under the gravity traction of weight; Circle scale about pointer can freely point in making on the index dial edge; When changing, the dip stick position causes the weight change in location; The interior pointer that its weight connects will change orientation angle, the numerical value of its variation that will clearly observe through transparent index dial up and down.And the netted coordinate line on the transparent outer pointed upper head plate outside surface free to rotate; It is initial value for setting measurement; Damped ring can make the outer pointer after the setting have stable sensing to stop; During use, the image film of X line, CT or MRI is hung on the film viewing light box of vertical placement, any two lines that on sheet, will measure then mark with light tight ink; With the dip stick body be placed on need measure on the sheet on the position; Adjust transparent outer pointer free to rotate make it with sheet on line that need to measure overlap, write down its with the interior pointed line that is connected weight between angle, calculate between two lines and the interior pointed line become the difference of alternate interior angle to be the angle between two lines.When measuring arbitrarily the data such as physical location, size and length of a bit, at first the engineer's scale on the slice, thin piece is overlapped the magnification of calculating image afterwards with netted coordinate line on the upper head plate outside surface; Subsequently the coordinate line on the dip stick body is covered on image data in the zone that needs to measure, the length of gained multiply by actual relative position, size and the length that magnification can be learnt any or figure in this zone at 2.

Because the utility model has designed the structure of pointer in the weight connection, serve as to need not to rule separately with pointed line in the weight with reference to the angle that can measure between any two lines, simplified the operation steps of measuring; The interior pointer of weight structure is connected in high, the good reproducibility of measuring accuracy in the rotating shaft with bearing, has improved the accuracy of measuring.Netted coordinate line on the upper head plate outside surface be through relatively can confirming the magnification of slice, thin piece with engineer's scale, and can confirm actual relative position, size and the length of any or figure in the coordinate overlay area at 2.The dip stick design is small and exquisite, simple in structure, alternative general measure chi, protractor and some measurement modules commonly used at present, and it is easy to use to be easy to carry.
