Description

Multifunctional measuring ruler for medical surgery

Technical field

The utility model relates to the technical field of medical instruments, in particular to a multifunctional measuring ruler for medical surgery.

technical background

In the clinical practice of spine surgery, it is necessary to quantitatively measure many spinal structures and the angles indicating the motion relationship between them, and to guide the diagnosis and treatment of diseases through measurement data. Currently commonly used measurement tools are complicated to operate and have low precision, which seriously affects the efficiency and quality of medical treatment. Therefore, it is necessary to design a medical and surgical multifunctional measuring ruler that can quickly measure angles commonly used in spinal X-ray, CT, and MRI image data, which is fast, easy, and high in measurement accuracy, to help judge the actual situation in spinal surgery. Data such as position, size and length, in order to guide the treatment of spinal surgery, this is also the task that this field is currently facing.

Invention content:

The purpose of the utility model is to provide a medical and surgical multifunctional measuring ruler with simple structure, fast and convenient measurement, and high measurement accuracy.

In order to achieve the above object, the utility model adopts the technical scheme of the following structure: a multifunctional measuring ruler for medical surgery, which consists of a lower end plate 1, an upper end plate 10, an upper dial 5, a lower dial 2, an outer pointer 4, and an inner pointer 3 , bearing 7, rotating shaft 8, weight 9, damping ring 6 and screw 11, which is characterized in that: the upper center of the transparent lower end plate and the upper end plate are each provided with a stepped circular through hole, two circular through holes Correspondingly, the lower part of the outer surface of the upper end plate is engraved with mesh coordinate lines; the circular transparent upper and lower dials are overlapped and stacked correspondingly, and the gap between the upper and lower dials is internally moved to fit the flat and long inner pointer. One end is connected with a flat weight; the center of the lower dial is designed with a bearing sink hole, and the center of the upper dial and the center of the oblong inner pointer have a bearing through hole; the center of the transparent outer pointer round head also has a bearing through hole; the upper scale The bearing through holes on the dial, inner pointer and outer pointer coincide with the bearing counterbore on the lower dial, and the stepped rotating shaft with a nut fits the bearing through the bearing through holes on the outer pointer, upper dial and inner pointer in turn , is located in the counterbore of the bearing on the lower dial, and the upper and lower end plates that overlap are riveted with screws to form a rectangular whole, forming a multifunctional measuring ruler for medical surgery.

The minimum division value of the scale marks on the above-mentioned upper and lower dials is 1 degree,

The minimum line spacing of the mesh coordinate lines on the outer surface of the upper end plate is 1 mm.

The inner pointer in the utility model rotates freely around the rotating shaft under the gravity traction of the weight, so that the inner pointer can freely point to a circle of scales on the edge of the upper and lower dials. When the position of the measuring ruler changes and the position of the weight changes, its weight The connected inner pointer will change the pointing angle, and the changing value can be clearly observed through the transparent upper and lower dials. The freely rotatable transparent outer pointer points to the mesh coordinate line on the outer surface of the upper end plate to set the initial value of the measurement. The damping ring can make the set outer pointer have a stable pointing stop. When in use, set the X Line, CT or MRI image film is hung on the vertically placed film viewing light box, and then any two lines to be measured are marked with opaque ink on the film, and the measuring ruler body is placed on the film to be measured. Adjust the freely rotatable transparent outer pointer to coincide with the line to be measured on the chip, record the angle between it and the line pointed by the inner pointer connected to the weight, and calculate the internal staggered angle between the two lines and the line pointed by the inner pointer The difference is the angle between the two lines. When measuring the actual position, size, length and other data of any point, firstly, the scale on the sheet coincides with the grid coordinate lines on the outer surface of the upper end plate to calculate the magnification of the image; then the coordinate lines on the measuring ruler body are masked In the area to be measured on the image data, the actual relative position, size and length of any two points or graphics in the area can be obtained by multiplying the obtained length by the magnification.

Because the utility model has designed the structure in which the weight is connected to the inner pointer, the angle between any two lines can be measured with reference to the pointer pointing line inside the weight without needing to draw another line, which simplifies the operation steps of the measurement; The inner pointer is connected to the rotating shaft by a bearing, which has high measurement accuracy and good repeatability, which improves the measurement accuracy. The mesh coordinate lines on the outer surface of the upper end plate can determine the magnification of the film by comparing with the scale bar, and can determine the actual relative position, size and length of any two points or graphics in the coordinate coverage area. The measuring ruler is compact in design and simple in structure, and can replace the general measuring ruler, protractor and some measuring templates commonly used at present, and is easy to carry and use.
