Abstract
The utility model discloses a computerized tomography (CT) or magnetic resonance imaging (MIC) intervention positioner. The positioner comprises an angle measurement device which is provided with a rotary ruler and a fixed ruler; the zero graduations of the rotary ruler and the fixed ruler and the central point of the angle measurement device are coincided; the zero lines of the fixed ruler and the angle measurement device are coincided; the rotary ruler is hinged with the angle measurement device; the hinge point is positioned at the zero graduation of the rotary ruler and the center of the angle measurement device; and a puncture groove is formed in the rotary ruler. During use, a puncture needle is placed in the groove of the rotary ruler, the fixed ruler can measure the horizontal distance, the rotary ruler can rotate arbitrarily along the fixed ruler, and the fixed ruler can determine the needle inserting depth and the rotation angle, so that the needle inserting angle can be determined. The positioner is simple in structure and accurate in positioning, and convenient to use and operate. Under the guide of the positioner, all the parts of a body can be accurately positioned.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates in particular to a kind of CT of being used in, MRI gets involved positioner.
Background technology
For CT or MRI location intervention diagnosis and treatment, at first will choose point of puncture, but present CT that uses or MRI intervention puncture locator location are inaccurate, use inconvenience flexibly, have directly influenced the therapeutic effect to the patient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency provides a kind of CT, MRI to get involved localizer.
The purpose of this utility model realizes through following technical scheme:
A kind of CT, MRI get involved localizer; Comprise angle-measuring equipment, angle-measuring equipment is provided with rotation scale and nonadjustable signal, and the zero graduation of rotation scale and nonadjustable signal is that central point overlaps with angle-measuring equipment; Nonadjustable signal overlaps with the zero degree line of angle-measuring equipment; The rotation scale is hinged on the angle-measuring equipment, and pin joint is in the zero graduation place of rotation scale and the center of angle-measuring equipment, and the rotation scale is provided with the puncture groove.
Above-mentioned CT, MRI get involved localizer, and described puncture groove is arranged on the side of the rotation scale parallel with angle-measuring equipment.
Above-mentioned CT, MRI get involved localizer, and described puncture groove is arranged on the side with the vertical rotation scale of angle-measuring equipment.
Above-mentioned CT, MRI get involved localizer, and the groove bottom of described puncture groove is and the corresponding circular arc of puncture needle shape.
Adopt technique scheme; This utility model has following advantage: during use, puncture needle is placed in the groove of rotation scale, nonadjustable signal can be measured horizontal range; The rotation scale can arbitrarily rotate along nonadjustable signal; Nonadjustable signal not only can be confirmed depth of needle, can also confirm the anglec of rotation, thereby confirms needle angle.This utility model is simple in structure, and is easy to use, and operation is convenient in accurate positioning.Under the guiding of this utility model, can accurately accurately locate each position of whole body.
