Abstract

The utility model relates to a measurer for measuring a distance and an angle, particularly a device of measuring the horizontal and the vertical distances from puncturing points to projective points of a stone body surface through skin kidney puncturing stolithotomy under the guiding of X-rays and reflecting the distance from the puncturing points to stone and the included angle between a puncturing needle or a fascia dilator and a horizontal plane surface. The utility model can measure through using a height gauge and a level bar which are vertically crossed, and can reflect the distance from the puncturing points to the stone and the included angle between the puncturing needle or the fascia dilator and the horizontal plane surface through an angle gauge and a protractor; the utility model solves the error of measurement, which is resulted in the surface irregularity of human body and people can measure the distance from the puncturing points to the stone and the included angle between the puncturing needle or the fascia dilator and the horizontal plane surface without calculating.

Description

Apart from the measurement of angle device

Technical field

The utility model relates to a kind of point of puncture of measuring to the level of calculus body surface projection point and the measurement mechanism of vertical range in the percutaneous renal puncture stone-extraction operation under the X ray guiding, especially can reflect point of puncture arrive the distance of calculus and puncture needle or fascia dilator and surface level angle apart from the measurement of angle device.

Background technology

At present, percutaneous renal puncture stone-extraction operation under the X ray guiding is vertical-horizontal direction perspective calculus when the patient is prostrate, the direction that faces toward calculus then, the adjustment puncture needle that does not stop or the angle of fascia dilator and surface level, puncture or expand, do not calculate point of puncture in advance to the distance of calculus and the angle of puncture needle or fascia dilator and surface level.Such operation existing problems have: 1, the radioscopy time long, operator and patient will accept many X-radiations; 2, because the degree of depth and the angle of the expansion of puncturing are unknown, puncture and expanded phase are failed easily to blindly.We have adopted a kind of new puncture scheme, allow X ray level and vertical-horizontal direction have an X-rayed calculus, and at back and belly hand mark calculus subpoint, measure the horizontal range of point of puncture and calculus back-projection point and the vertical range of point of puncture and calculus belly side projection point respectively, calculate point of puncture to the distance of calculus and the angle of puncture needle or fascia dilator and surface level according to the corner relation of right-angle triangle again.But because human body surface is uneven, common ruler or tape measure can't accurately be measured level or the vertical range between them, and to calculate point of puncture to the distance of calculus and the angle of puncture needle or fascia dilator and surface level, measurements and calculations more complicated with trigonometric function.

The utility model content

For overcome common ruler can't measure the level of human body surface point-to-point transmission and vertical range exactly and measure after to calculate the deficiency of point of puncture to the angle of the distance of calculus and puncture needle or fascia dilator and surface level, it is a kind of apart from the measurement of angle device that the utility model provides, by height gauge, surveyor's staff, bevel protractor, protractor and level meter are formed, this not only can accurately measure level and the vertical range of point of puncture to calculus body surface projection point apart from the measurement of angle device, and reflects that fast point of puncture arrives the distance of calculus and the angle of puncture needle or fascia dilator and surface level.

The technical scheme of the utility model technical solution problem is, height gauge, surveyor's staff are adjusted to plumbness, when measuring point of puncture to calculus back-projection point horizontal range, height gauge is placed on these 2, align with point of puncture the zero point of height gauge, because the point of puncture position is lower than calculus subpoint position, back, regulates surveyor's staff, make the height gauge level, the distance that height gauge is measured is exactly a horizontal range between 2; When measuring point of puncture to calculus belly side projection point vertical range, height gauge is placed on these 2, align with point of puncture the zero point of height gauge, because the point of puncture position is than the more close human body of calculus subpoint inboard, belly side, regulate surveyor's staff, make the surveyor's staff level, the distance that height gauge is measured is exactly a vertical range between 2, reaches the purpose of accurate measurement human body point-to-point transmission level and vertical range.Height gauge, surveyor's staff keeps plumbness, the pull-up bevel protractor, allow it and surveyor's staff, height gauge surrounds right-angle triangle, with the length adjustment on the limit that surveyor's staff constituted length to the horizontal range of having measured, with the length adjustment on the limit that height gauge constituted length to the vertical range of having measured, the length of the hypotenuse that bevel protractor constituted is exactly the distance of point of puncture to calculus, the degree of depth of puncture expansion just, the angle that bevel protractor and protractor zero degree line are constituted is exactly the angle of puncture needle or fascia dilator and surface level, reaches to calculate just to reflect fast that point of puncture arrives the purpose of the angle of the distance of calculus and puncture needle or fascia dilator and surface level.

The utility model beneficial effect is, solves because the uneven error measured of causing of human body surface, and reflects that fast point of puncture arrives the distance of calculus and the angle of puncture needle or fascia dilator and surface level, and is simple in structure, making easily.
