Description
Technical field
This utility model relates to technical field of medical instruments, specifically numerical control conformal therapy bed.
Background technology
When carrying out radiotherapy, the patient generally puts the position outside therapy apparatus, again by therapeutic bed automatically or manually the patient is sent into therapy system focus or etc. the center, could implement irradiation treatment then.Therefore the positioning accuracy of focus directly affects therapeutic effect.At present, on the market radiotherapy equipment as the CO60 therapy apparatus, clinac, therapy system such as body gamma knife, its therapeutic bed all adopts the elevating mechanism of shears posture.This structure the characteristics of therapeutic bed be therapeutic bed can fall lower, be convenient to operator to the patient put position and patient about.But its positioning accuracy is low, less stable, and also reliability is also lower.And these deficiencies will be brought very adverse influence for modern precise radiotherapy.
Summary of the invention
This utility model is for when the radiotherapy, and patient's focus is carried out accurately that location and tracking automatically scan conformal radiation therapy and the therapeutic bed of a kind of new structure of providing.
Numerical control conformal therapy bed of the present utility model: comprise bed surface, pedestal, it is forward and backward, upper and lower that lathe bed is housed respectively between bed surface and the pedestal, the drive mechanism of left and right motion, numerical control device.
The drive mechanism that seesaws comprises: the nut, the linear rolling track that link to each other with bed surface are paid, the screw mandrel that links to each other with nut, there is supporting base at screw mandrel two, and of screw mandrel links to each other with motor, supporting base links to each other with the ground floor bearing support with motor, and linear rolling track is paid and comprised: roller, guide rail.
Upper and lower motion gear comprises: guide pillar, screw mandrel link to each other with the ground floor bearing support respectively, and motor, decelerator and driving member link to each other, and the other end of guide pillar links to each other with guide pin bushing, guide pin bushing, and motor, decelerator, driving member all are contained on the second layer bearing support.Guiding mechanism is a cylinder ball line slideway, and the transmission that partners of screw mandrel and driving member is paid.
Left and right motion gear comprises: the nut that links to each other with second layer bearing support, and the screw mandrel that links to each other with nut, the bearing that screw mandrel two links to each other, one of screw mandrel link to each other with motor, and linear rolling track is paid with second layer bearing support, pedestal and is linked to each other, and bearing is contained on the pedestal.Guide rail, the roller set rolling guide that is in line is paid.
The motor of three directions is controlled by motion controller, and drive motors is a motor, and motion controller is electrical equipment control commonly used.
The advantage of this utility model numerical control conformal therapy bed is:
1, straight-line rolling and cylinder ball line slideway guiding are all adopted in the motion of all directions supporting, have the motion good rigidly, positioning accuracy height, good stability, reliability height.
2, owing to adopted the numerical control motion controller control that has by three-shaft linkage is arranged, can realize focusing tracking scanning conformal radiation therapy.
3, stroke is big up and down, and treatment pendulum position is convenient, and the patient is easy up and down.
4, drive motors selects for use motor to make that treatment is safer.
