Description

CT, MRI cephalometry 3 D locating device

Technical field

This utility model relates to a kind of armarium, promptly a kind of CT, MRI cephalometry 3 D locating device.

Background technology

CT, MRI are present more advanced medical inspection equipment, particularly have important effect in the diagnosis of cranium disease of brain.CT, MRI are many in cranium disease of brain diagnosis to obtain three-dimensional image information by cephalometry, thereby provides foundation for diagnosis.The accuracy of cephalometry often depends on the correctness and the stability of testee position.That is to say that the head position of being examined the people must be correct, and can not touch.In order to accomplish this point, existing C T and MRI have been equipped with special moving bed, and the head of a bed is provided with the U type headstock, and detected person's this headstock of resting the head on is just thought to be in preferably the position., facts have proved that this headstock can't play accurate localized effect.Because on this headstock, do not set the three-dimensional localization benchmark.If the vertical center line with bed is an X-axis, with bed laterally be Y-axis, be the Z axle with the vertical line of bed surface, this headstock all can not produce the restriction of essence around the deflection of three axis to head.Wherein, because receptor's health and operator's sensation, the deflection of relative Z axle of head or Y-axis is easily near exact value, and the deflection of X-axis then is difficult to correct relatively.Therefore, the detected person does not know how to ajust the position of head, is difficult to overcome the deviation that involuntary movement causes yet.The operator also can only come to determine the position of receptor's head by feel, is difficult to the precision that reaches higher.The uncertainty of this position is often brought the uncertainty of measurement result, brings difficulty to diagnosis.

Summary of the invention

The purpose of this utility model provides a kind of CT, the MRI cephalometry 3 D locating device that can accurately locate the detected material position.

Above-mentioned purpose is realized by following technical scheme: develop a kind of CT, MRI cephalometry 3 D locating device, comprise CT or MRI body and moving bed, different is: in the front portion of said moving bed, the head three-dimensional locator is housed.

Said head three-dimensional locator has a box-like console panel, many locating detents are housed below the console panel, the console panel the inside is provided with the telescoping mechanism of control locating detent plan-position, and the joystick of telescoping mechanism is housed above the console panel, and console panel one side is equipped with the hanging plate that articulates mutually with moving bed.

Locating detent below the said console panel has three, and the mounting points on positioning disk constitutes triangle, and the length of every locating detent is all adjustable.

Said telescoping mechanism has one to be contained in the intermediary rotating shaft of console panel, the fork that is connected below the rotating shaft, and the fork two ends one section pull bar that is hinged respectively, the pull bar other end all is hinged in the upper end of locating detent, and locating detent is assemblied in the chute of console panel.

The beneficial effects of the utility model are: at the anterior assembling of moving bed three-dimensional locator, can be accurately the fixing position of head, thereby obtain the image information of standard, for diagnosis provides reliable basis.And under the prerequisite of not destroying existing structure, its performance is significantly improved, has characteristics such as simple in structure, easy to operate, cheap, thereby have higher utility and good market prospect by simple transformation.

Among the figure as seen: moving bed 1, head three-dimensional locator 2, locating detent 3, console panel 4, handle 5, pawl cover 6, slotted hole 7, fixing button 8, claw 9, hanging plate 10, slide block 11, rotating shaft 12, fork 13, pull bar 14, chute 15.

The specific embodiment

As shown in Figure 1, 2, this CT, MRI cephalometry 3 D locating device are a kind of head three-dimensional locators 2 of assembling on the moving bed 1 of CT or MRI.In conjunction with Fig. 3,4,5,6 as seen, this head three-dimensional locator 2 has a box-like console panel 4, many locating detents 3 are housed below the console panel 4, console panel 4 the insides are provided with the telescoping mechanism of control locating detent 3 plan-positions, the joystick 5 of telescoping mechanism is housed above the console panel 4, and console panel 4 one sides are equipped with the hanging plate 10 that articulates mutually with moving bed 1.

Obviously, the length of locating detent 3 and plan-position, place need to adjust at work, and the mode of adjusting has multiple.Fig. 3,4,5 has only exemplified a kind of mode: shown in Fig. 3,4, locating detent 3 is to constitute by two sections, epimere is to be connected in console panel 4 following pawls to overlap 6, on the pawl cover 6 slotted hole 7 is arranged, hypomere is to overlap the claw 9 that slides up and down in 6 at pawl, and fixing button 8 is arranged at claw 9 tops, and fixing button 8 stretches out slotted hole 7, so just can adjust the upper-lower position of claw 9, again by fixing button 8 fixing getting final product.

Fig. 5 has introduced a kind of telescoping mechanism of adjusting locating detent 3 plan-positions.Telescoping mechanism has one to be contained in console panel 4 intermediary rotating shafts 12, a system fork 13 is connected below the rotating shaft 12, the fork 13 two ends one section pull bar 14 that is hinged respectively, on the slide block 11 of pull bar 14 other end hinge locating detents 3 upper ends, slide block 11 is assemblied in 15 li of the chutes of console panel 4.Pull handle 5, rotating shaft 12 rotations drive fork 13 swings, and the slide block 11 that can pass through pull bar 14 pulling locating detents 3 upper ends is in 15 li slips of chute, thus the plan-position of change locating detent 3.

Fig. 6,7 has introduced a kind of duty of this device.As seen from the figure, three locating detents 3 adjusting localizer 1 are relative with the specified point of receptor's head, promptly determined the space reference position of head, thereby guarantee the correctness of receptor's head position, the high-level image information that can obtain.
