Description
Technology neck city
This utility model relates to the therapeutic bed of gamma ray therapeutic apparatus, especially relates to a kind of therapeutic bed slew gear.
Background technology
The therapeutic bed of gamma ray therapeutic apparatus generally has only the motion of rectilinear coordinates axle (as X-axis, Y-axis, Z axle), the treatment positioning action when therapeutic bed only plays patient.Patient needs to carry out the detection of lesions position before treatment, must walk or escort CT Room, lies in earlier on the CT diagnostic bed and does x-ray tomography, determines that tumor is at the intravital three-dimensional position of patient.Then, X-axis, Y-axis, the Z axis data of the tumor of these CT detections are transported to gamma ray therapeutic apparatus, become the gamma-ray therapeutic focus data of therapeutic bed.Patient walks or escorts the gamma-ray therapeutic chamber, lies in the treatment location of focus when treating on the therapeutic bed for the second time.Present " second positioning " method of gamma ray therapeutic apparatus that Here it is, and each location (CT detection and location and gamma treatment location) all can produce error, the accumulation of error of second positioning makes final treatment error ratio bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of therapeutic bed slew gear, can carry out the detection and location of patient's knub position of CT equipment after making therapeutic bed turn over 90 degree, and therapeutic bed goes back to the treatment that 90 degree just can be done gamma ray at once then.
The technical scheme that its technical problem that solves this utility model adopts is:
Be included in the stepped bore at pedestal center chassis and floating bearing are housed from bottom to up successively, the platen that is contained on the pedestal is pressed in the floating bearing end face, pack in the floating bearing hole in the revolving body lower end, be connected with the chassis with screw, the rolling of floating bearing drives the relative pedestal of therapeutic bed and does gyration, on 0 ° of one side end face of pedestal, positioner is housed, revolving body downside above positioner is equipped with locating piece, in 90 ° of positions of revolving body downside another locating piece is housed, on the end face of 180 ° of one side of pedestal, gusset is housed, locking device is housed on the gusset, the alignment pin of locking device can insert in the locating slot that is contained in the lateral latch segment of revolving body, and another latch segment is equipped with in revolving body side 180 ° positions opposite with another locating piece.
The useful effect that the utlity model has is:
1. connect by rolling bearing between therapeutic bed and the pedestal, therapeutic bed is flexible, light with respect to the revolution of pedestal, as long as just can finish two functions of detection and location and treatment location after patient one-time fixes in bed, eliminated the accumulation of error, improved the treatment precision;
2. disposable location has avoided patient to come and go CT Room detection and location and therapeutic room treatment location, has shortened the cycle of treatment, has alleviated patient's misery;
3. therapeutic bed has very big preparation bit space before treatment, helps the doctor patient is carried out fixing operation.
