Description
Technical field
This utility model relates to the X ray technology, relates to especially can be used as the functional universal device and being used in scanning digital equipment in the diagnostic medical X-ray system.
Background technology
The multi-functional X-ray system of similar RUM-20, TUP-800 and EDR-750 is widely used now.They comprise three operating positions, promptly have the radioscopic image amplifier rotatable brace table, be used to have tomography with the estrade of the X-ray photographs of adnexa be used for the support of X-ray photographs.Multi-functional X-ray equipment almost provides all types of radiodiagnosis inspections.Local tomography and special X-ray examination account at the most 10% and be specified in the common operation process of total inspection.Such multi-functional X-ray equipment is very expensive and operation is very complicated.They in medical facility also in occupation of very big area, and should be installed in the nurse chamber of hospital and trauma center special-purpose X-ray room separated by a distance in.In the nurse chamber of hospital and trauma center, the plain film of some part of patient body needs most.Most important factor be check the required time of the image that receives.Therefore, the diagnosis that is used for the nurse chamber of hospital and trauma center must be satisfied some strict requirement with X-ray equipment.
At first, this equipment should be provided for not only showing the wound of health, head and extremity, the fragment of osseous tissue effectively, and the useful X-ray photographs of the internal structure of display organization (position that comprises inflammation, tumor and other disease).
The second, the image that obtains must be as far as possible near common X-ray photographs, like this, they can be understood by most of lonizing radiation experts.
The 3rd, this equipment should be enough little, in the finite region with the nurse chamber that is contained in hospital and trauma center.
The scanning X-ray apparatus is known (Russian Academy Of Sciences Siberia branch nuclear physics institute, the advertisement booklet of multi-functional X-ray equipment " Cibir ", adnexa 1) in the prior art.This equipment comprises x-ray source, slit collimator and the linear X ray receptor of arranging along an optical axis, wherein, radiographic source, collimator and receptor adopt common carriage to be connected rigidly mutually, and move along perpendicular with respect to the target that is placed between slit collimator and the linear X ray receptor.
The major defect of this equipment is that it only is used for the restriction that work up (particularly fluorogaphy) is in the patient of vertical position.Consider from the viewpoint of information value, this patient's X-ray examination for other type is not enough, because in some cases, the image that information is more arranged that the position of level or inclination causes describing in the position system (is seen A.N.Kishkovsky, L.A.Tutin, the position atlas that is used for X-ray examination of G.N.Esinovskaya; MeditsinaPublishers, Leningrad, 1987).
And because the fan-shaped of X ray dispersed, the size that is examined target that adopts known device to obtain is exaggerated on horizontal plane, but because the slit fan-shaped x-ray beam moves along being examined the parallel of target, does not amplify on perpendicular.As a result, the ratio of the image that is obtained is distorted basically, and this causes the doctor to understand the difficulty of photo.
The rotatable bracing frame that is used for digital X-ray equipment is known (seeing patent RU2202953, Cl.A61B6/04,2003) in the prior art.This support comprises: be connected to pedestal and rotating mechanism thereof on the support frame; Be connected to the supporting walls on the support frame; The vehicle frame that vertically moves with linear movement mechanism; Be fixed to the cantilever on the vehicle frame that can vertically move rigidly, described cantilever support has the swing U-shaped bar of angular displacement mechanism, and wherein, x-ray source is arranged on the relative arm of U-shaped bar with the X ray receptor.This equipment almost can provide the diagnosis X-ray examination of any type or combination.
The major defect of known equipment is that its basic size and weight have limited it widely as the functional performance that is suitable for checking and being used in the universal design in the surgical procedures in the ward.
The immediate reference of utility model required for protection (original shape) is the scanning X-ray equipment of the x-ray source, collimator and the linear multiple-unit X-ray detector that comprise whole coaxial arrangement.These parts are installed on the single carriage, and this carriage can rotate (seeing PCT application publication number WO02/17790, Cl.A61b6/03,2002) around the longitudinal axis of scan axis in the plane of collimator slit and linear multiple-unit X-ray detector.This equipment is generally used for obtaining the digital X-ray photo of vertical localized patient body.
The major defect of known equipment is can't be as the multifunctional diagnosis apparatus of the complicated projection that obtains organ or extremity.
Summary of the invention
The technical problems to be solved in the utility model is to overcome described shortcoming, improves the functional performance of this equipment in particular.
Diagnosis required for protection comprises sequentially along single optical axis with X-ray equipment arranges and is installed in x-ray source, slit collimator and linear multiple-unit X-ray detector on the single carriage, and this bracket arrangement becomes can be around the longitudinal axis rotation of scan axis in the plane of collimator slit and linear multiple-unit X-ray detector.
Described technical problem is solved owing to be installed in the carriage on the shape of a hoof framework movably, and this framework is connected on the platform under the help of rotating mechanism and rotating mechanism, and wherein, this platform is fixed on the vertical frame.Such layout provides the level of freedom of framework, and carriage makes that the image of information value can be arranged with different angle shot images and acquisition with respect to patient's body most.
Platform is installed on the vertical frame movably, and is provided with and is used for along the reciprocating mechanism of its longitudinal axis, to regulate required irradiation height (checking skull, thoracic cavity, pelvis etc.).This platform also is provided with the mechanism that is used for around the longitudinal axis rotation of frame, to regulate comfortable position with respect to patient body.
In order to select required irradiating angle, the rotating mechanism of shape of a hoof framework provides around the rotation of the axis parallel with scan axis, is used for respect to the angled irradiation of the vertical axis of frame.
In addition, below the patient's body that the rotation of framework is used for its part with detector is positioned to lie on a bed.During the patient that is in a bad way in checking the ward, this is important especially.
In order to select required irradiating angle, the rotating mechanism of shape of a hoof framework is designed to and can rotates around the axis parallel with the vertical axis of frame, and this makes can take the photo that adopts X-ray equipment with horizontal shore not take.
The rotating mechanism of shape of a hoof framework is made based on the dual-axis universal joint driver element that is used to provide high activeness and required rigidity (biaxial cardan drive unit).
The rotating mechanism of shape of a hoof framework has the reversible gear motor that is used for rotation axis, with this system of control in the process of regulating required irradiating angle.
In order to provide rigidity in the rotation process of dual-axis universal joint driver element, rotating mechanism is arranged in U-shaped and sticks, and this U-shaped fork can rotate and have reversible gear motor around the axis with vertical frame axis normal.
In order equipment to be had be independent of the versatility of the maximum in particular type room, it can have vertical frame, and this vertical frame has the unit that is used to be installed on floor, ceiling or the wall.
In order to diagnose the patient who is in a bad way in the ward, the vertical frame of this equipment can be installed in movably on the pedestal.
