Abstract
The utility model discloses the removable positioning head frame of a kind of CT scan, comprise vertical mobile device, horizontally moving device and the headstock.This utility model makes by horizontally moving device and vertical movement apparatus that the headstock can position be adjustable up and down, by increasing spring on the headstock, headstock both sides are inwardly had and steps up effect, thus the head face of fixing patient upward, prevent scanning front patient and change position instantaneously, cause rechecking thus increase radiation dose.Utilize the bar-shaped marks thing on the right side of the headstock simultaneously, help CT diagnostician and clinicist accurately to judge the left and right sides cerebral hemisphere of patient head CT image.
Description
Technical field
This utility model belongs to field of medical appliances, particularly relates to the removable positioning head frame of a kind of CT scan.
Background technology
The emergency case of whole body plyability, major trauma is accompanied by nurse, push emergency treatment flatcar to come my section and go to a doctor, in order to reduce patient move to avoid damage for 2 times of patient (especially the patient of spinal trauma), shorten the review time, families of patients can be enjoined directly to be moved to by flatcar by CT scan bed, parallel and neat by two, by family members the mattress on patient and emergency treatment flatcar thereof together level is moved to scanning bed on.Add scanning bed height with regard to artificial like this, cause patient head can not insert in the intrinsic headstock of CT machine, patient head can not get effective fixing.The scanning headstock that conventional CT machine is intrinsic cannot move, if by force patient to be put into the intrinsic scanning headstock of CT, due to the increase of scanning bed height, patient head can be caused to swing back, CT machine reaches parallel with timebase (extending the review time) with regard to needing to tilt larger angle, but the angle of inclination of CT machine is limited (about positive and negative 29 degree).Some patients can cause timebase lack of standardization because head reclined by angle is excessive, thus affects picture quality.
Some patients can due to restless reason, and head can not get effectively fixing, changes position instantaneously before scanning, causes rechecking thus increases radiation dose.
Conventional CT examination requires that patient gets dorsal position, and CT machine is with dorsal position image for benchmark carries out left and right labelling to image, so must the good position of prioritizing selection before CT scan, this point be even more important.If the position selected and the actual position of patient are not inconsistent, the position of image and actual lesion will be caused not to be inconsistent.Be exactly briefly: focus is actual in left hemisphere, but on CT image marked lesion at right hemisphere.If atypical symptoms, department of cerebral surgery doctor directly opens according to CT image the words that cranium performs an operation certainly will cause medical tangle, increase patient mentally, sensual misery, even cause death.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of CT scan removable positioning head frame.
This utility model solves its technical problem and is achieved through the following technical solutions:
The removable positioning head frame of CT scan comprises, vertical mobile device, horizontally moving device and the headstock.
Described vertical mobile device comprises, puller bolt, female thread cylinder, connecting rod, the 3rd guide rail and support bar.Puller bolt puts in female thread cylinder by threaded engagement; Puller bolt is rotatably fixed on support bar by bearing (not marking in figure); Female thread cylinder is fixedly connected with one end of connecting rod, and the other end of connecting rod is movably connected with the 3rd guide rail, and the 3rd guide rail is vertically fixed on lathe bed, can move both vertically to make female thread cylinder and connecting rod on the 3rd guide rail;
Described horizontally moving device comprises, gripper shoe and guide rail, and guide rail comprises the first guide rail and the second guide rail, its level and be arranged on the upper surface of gripper shoe parallel to each other; Gripper shoe lower surface is fixedly connected with the upper surface of female thread cylinder;
The described headstock comprises, the upper headstock and the lower headstock, wherein go up the headstock and comprise the upper left headstock and the upper right headstock, the upper left headstock is connected with the lower headstock with right spring assembly respectively by left spring device with the upper right headstock, to make the upper left headstock and the upper right headstock can folding, and inwardly have and step up effect; The lower headstock is arranged on the guide rail of horizontally moving device movably, to make the whole headstock can at slide on rails; Upper right headstock outer surface is adhesive with bar-shaped marks thing.
Described bar-shaped marks thing length can not be as short as very much and be greater than 5mm (CT scan thickness is 5mm) less, is preferably 5-10mm, and hardness wants high, CT image can be seen but can not stay artifact.After the headstock adds labelling, the left and right mark of scanogram all can conform to practical situation, so just relieves the puzzlement of CT diagnostician and clinicist, solves the mistake that anthropic factor causes, shorten the review time, improve rate of correct diagnosis.
During use, the height of the headstock is regulated by rotating puller bolt, and adjust the position of the headstock on the guide rail of horizontally moving device, accurately cosily rest the head on into the headstock to make the head of patient, because the upper left headstock of the headstock and the upper right headstock can foldings inwardly have and step up effect, thus the head face of fixing patient upward, prevents scanning front patient and change position instantaneously, cause rechecking thus increase radiation dose.Utilize the bar-shaped marks thing on the right side of the headstock simultaneously, help CT diagnostician and clinicist accurately to judge the left and right sides cerebral hemisphere of patient head CT image.
