Abstract

The utility model discloses a sagittal CT scan fixing frame for heads, which is composed of a rectangular bottom board 1 and a rectangular head supporting board 2. The inner side edge of the rectangular bottom board 1 is connected with the lower side edge of the rectangular head supporting board 2 through a rotary shaft 3, and an included angle is formed. The middle part of the utility model is provided with a radian adjusting supporting bar 4. Upper clamping heads 5, 5' are respectively fixed on the left side and the right side of the rectangular head supporting board 2, and radian indicator boards 6, 6' are respectively fixed on a left corner and a right corner of the outer side of the rectangular bottom board 1. The utility model has the advantages of simple structure, convenient use, flexible adjustment for the side lying inclination of a head, and stable head fixation. The utility model is especially is suitable for the sagittal scan of the head when a patient is in a side lying posture, and is favorable for the intersecting or coronal CT scan of the head of the patient. Part of the functions of the utility model can take the place of magnetic resonance, which is favorable for scanning and diagnosing subtle pathologic changes, such as the bone fracture of orbit walls and intraocular muscle, etc.

Description

Head CT sagittal scanning fixed mount

Technical field

This utility model relates to a kind of auxiliary device of head CT scanning, particularly a kind of head CT sagittal scanning fixed mount.

Background technology

Generally all locate for intracranial hematoma, tumor, inflammatory lesions by the CT scan imaging, because the skull quality is tight, complex structure, many holes, nest, ditch, the scanning split are all required certain special angle, this angle was fixing in the past, all be with special angle board fixed mount, but at present the angle board fixed mount that uses mostly is greatly and is fit to that the patient lies on the back or prostrate, is not suitable for patient's use of lying on one's side.Yet,, show as orbit wall fracture or ophthalmic flesh in some trickle pathological changes, then needing the patient is lateral position, the head certain angle of deflection that also will make progress is along sagittal scan, so the CT scan head angle fixed mount that uses is not suitable for parasagittal CT scan at present.

Summary of the invention

The purpose of this utility model is to provide a kind of head CT sagittal scanning fixed mount that is applicable to along the trickle pathological changes CT scan of head sagittal plane.

For reaching above purpose, the technical scheme that this utility model adopted is: this head CT sagittal scanning fixed mount, by the rectangle base plate, a rectangle holder plate constitutes, it is characterized in that being connected by turning cylinder with the lower side edge of a rectangle holder plate on the inner side edge edge of rectangle base plate, make a rectangle holder plate and rectangle base plate form an adjustable angle, regulating support bar along the middle part by radian in the outer side edges of rectangle base plate is connected along the middle part with the upper side edge of a rectangle holder plate, regulate the adjusting of support bar length by radian, realize the adjusting of a rectangle holder plate and rectangle base plate angle, thereby regulate the angle of inclination of a rectangle holder plate, left side at a rectangle holder plate, the fixing respectively head-clamp of going up in right side, be clipped in the forehead position, center and the rear pillow part position of patient's head respectively, left side on the outer side edges edge of rectangle base plate, the fixing respectively radian indicator board of going up of right corner portion, on the radian indicator board, be respectively equipped with slide opening, slider is all established at two angles on a rectangle holder plate upper side edge edge, slider inserts in the slide opening of corresponding radian indicator board, and use bolting, the effect of radian indicator board: the one, can directly mark the angle angle of a rectangle holder plate and rectangle base plate, and the angle of inclination that can extrapolate a rectangle holder plate, can play a supportive role to a rectangle holder plate on the other hand, keep a rectangle holder plate in one plane, and have certain intensity; This utility model is also implemented by following measure: described radian is regulated support bar and is made of positive and negative screw rod, barrel, bulb and bulb moving block, one end of positive and negative screw rod is rotated in the barrel, the fixing respectively bulb of going up of the other end of positive and negative screw rod, bulb is stuck in the cave of corresponding bulb moving block, and the bulb moving block is separately fixed at the middle part of a rectangle base plate and a rectangle holder plate; Described head-clamp constitutes by fixing head, circular cushion, screw rod, rotation seat, rotation seat is fixed on the lateral surface of circular cushion, screw rod passes the screw on the fixing head, the rotation disk of its end is stuck in the rotation seat groove, fixing head is fixed on the plate face of a rectangle holder plate, by the rotation adjustment of screw rod, circular cushion inwardly or is outwards stretched, thus clamping patient head; A described rectangle holder plate, rectangle base plate and adjusting support bar, radian indicator board, chuck are all made of plastic material.When using this utility model, the patient lies on the back, and head is placed on the rectangle holder plate fixing, regulates the angle of inclination, and it is left and right to make head raise 70 degree, adjusts the gantry position then, can realize along the head sagittal scan.

The beneficial effects of the utility model are: simple in structure, easy to use, being specially adapted to patient's lateral position scans the head sagittal, also help cross-section, the crown CT scan of patient's head, partial action also can replace magnetic resonance, is beneficial to the diagnosis of scans such as trickle pathological changes such as orbit wall fracture and ophthalmic fleshes.
