Description
Technical field
This utility model relates to a kind of head fixing device of CT radiography.
Background technology
When dental care or head face-lifting, need to scan the head of patient, to determine skull shape and the health status of patient, to ensure the reliability implementing operation.When carrying out head radiography, need patient stand at CT equipment place, patient, when accepting CT radiography, needs to keep the static of head, the definition of the image of radiography to ensure.But the head of patient cannot keep stable for a long time mostly, and this kind of needs of patients accepts repeatedly radiography, causes larger radiation injury to the head of patient.
For these reasons, need to provide a kind of can the device of the head of position patient preferably, to ensure the head fixing device of Cranial Computed Tomography radiography success rate.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of head fixing device of CT radiography, this device can carry out three-point fix to the head of patient, ensure the fixing reliability of the head of patient, the head of patient when accepting CT radiography is avoided to move, improve the success rate of patient CT radiography, reduce the radiation injury suffered by patient.
For solving the problem, this utility model adopts following technical scheme:
A kind of head fixing device of CT radiography, comprise the cervical region location-plate of a U-shaped, the top of described cervical region location-plate is provided with the first holder and the second holder, described second holder is symmetrically arranged with two, the top of described first holder is provided with the first fixing hole that runs through described cervical region location-plate, motion bar is combined with in described first fixing hole, the top of described motion bar is provided with the supporting pad supporting chin, the first lock screw is combined with between described first holder and described motion bar, support bar has been assigned in described second holder, the shaft of described support bar is combined with movable sleeve, the medial surface of described movable sleeve is provided with lateral support pad, the second lock screw is combined with between described movable sleeve and described support bar.
As preferably technical scheme, the thickness of described cervical region location-plate is 10mm-25mm, and described cervical region location-plate is PVC plastic flitch, described cervical region location-plate prolong position, limit arc transition.
As preferably technical scheme, the upper surface of described supporting pad is provided with the corresponding groove of a human body chin, and described supporting pad is rubber blanket.
As preferably technical scheme, the medial surface of described lateral support pad is provided with the first groove that a human head profile is corresponding, described lateral support pad is foam-rubber cushion or cotton pad.
As preferably technical scheme, the close tip position place of described support bar is provided with the limited block limiting described movable sleeve displacement.
The beneficial effects of the utility model are: this device can carry out three-point fix to the head of patient, ensure the fixing reliability of the head of patient, the head of patient when accepting CT radiography is avoided to move, improve the success rate of patient CT radiography, reduce the radiation injury suffered by patient, the structure of this device is comparatively simple simultaneously, regulates more for convenience, is applicable to promoting the use of.
