Description
Technical field
This utility model relates to a kind of medical aid, the position holding device particularly used when a kind of radioscopy or treatment.
Background technology
Need specifically to take pictures position in irradiation image inspection, as normotopia, position, side, Double oblique etc., position accurate, can ensure that clinician diagnoses accurately.In existing radiology department checking process, the maintenance of position relies on the control force of self to locate more, or family members help, and the former changes, is shifted because of patient pain or the unable angle that easily causes, and affects diagnostic accuracy; The latter then can cause family members to accept unnecessary radiation injury.
In addition, the position of radiation Postural immobilization can be changeable, and limbs fixed diameter is little, and the body such as breast, abdomen fixed diameter is large, and, chest is fixed, also will fully take into account and retain the certain Breathing movement of thorax.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of simple and efficient radiation position holding device.
The technical scheme in the invention for solving the technical problem is: a kind of radiation position holding device, is characterized in that: comprise guide post, leading screw, frame plate and two fixture blocks; Described frame plate two ends have a through hole and screwed hole respectively, and one end of described guide post is connected with radiation bed board through the through hole of frame plate, one end of leading screw through frame plate screwed hole and radiate bed board and be rotatably connected; Described leading screw top is connected with hands wheel; Described frame plate is hollow, above has a notch; Have screw rod in frame plate cavity, described fixture block has through hole, and screw rod is successively through the through hole of nut thread hole, two fixture blocks, and two ends are connected with frame plate end walls respectively; Described nut, two fixture blocks are exposed in frame plate notch; Be connected by spring between nut with frame plate sidewall; Respectively be connected with a tooth bar below two described fixture blocks, the teeth groove of two tooth bars is relative, and is meshed with same gear, and gear and frame plate bottom surface are for being rotatably connected.
Above above-mentioned fixture block by torsion spring and flap hinged.
Compared with prior art, this utility model can regulate the height and the width of fixture block by rotating threaded shaft, thus can meet the demand of the different fixed position of patient; And two side flaps have torsion spring resilient support, a part of activity space can be retained, be suitable for thorax equally and fix.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is rack-and-pinion relation schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, this utility model comprises guide post 1, leading screw 2, frame plate 3 and two fixture blocks 4.
Described frame plate 3 two ends have a through hole and screwed hole respectively, and one end of described guide post 1 is connected with radiation bed board through the through hole of frame plate 3, one end of leading screw 2 through frame plate 3 screwed hole and radiate bed board and be rotatably connected.Described leading screw 2 top is connected with handwheel 5, and when rotation hand wheel 5, handwheel 5 drives leading screw 2 to rotate, thus frame plate 3 can be made to move along the direction of guide post 1.
Described frame plate 3 is hollow, above has a notch.Have screw rod 6 in frame plate 3 cavity, described fixture block 4 has through hole, and screw rod 6 is successively through the through hole of nut 7 screwed hole, two fixture blocks 4, and two ends are connected with frame plate 3 end walls respectively.Have screwed hole in nut 7, the screwed hole on described nut 7 is threaded with screw rod 6, and nut 7 can carry out spacing to fixture block 4, and fixture block 4 plays spacing maintenance effect for trunk or limbs.Described nut 7, two fixture blocks 4 are exposed in frame plate 3 notch.
In prioritization scheme, be connected by spring 8 between nut 7 with frame plate 3 sidewall, it is loosening that spring 8 can prevent nut 7 from producing due to the effect of external force.
As shown in Figure 1, 2, the teeth groove being respectively connected with tooth bar 8, two tooth bar 8 below two described fixture blocks 4 is relative, and is meshed with same gear 9, and gear 9 and frame plate 3 bottom surface are for being rotatably connected.When the fixture block 4 promoting side moves, this side tooth bar 8 driven gear 9 moves, thus makes offside tooth bar 8 move toward one another, with the central authorities keeping radiation part to be positioned at radiation bed.
In prioritization scheme, above described fixture block 4 by torsion spring and flap 11 hinged, its objective is when irradiated site is thoracic cavity, the distance between two flaps 11 can produce slight change with Breathing movement.
Operating process is as follows: rotation hand wheel 5 during use this utility model, and handwheel 5 drives leading screw 2 to rotate, and frame plate 3 can be made to move along the direction of guide post 1, thus regulates the height of frame plate 3.Stretching or promoting a fixture block 4 is fixed on frame plate 3 by the position to be illuminated of patient, and swivel nut 7 pairs of fixture blocks 4 fix.
