Abstract
The utility model provides a three dimensional positioning bed, which belongs to medical diagnosis and therapy equipment, in particular relates to a positioning device for radiotherapy the focus of the patient. The upper end of the pedestal of the positioning bed is divided into a surface layer, a middle layer and a lower layer, each layer is driven by a stepping motor controlled by a computer, the moving support uses a linear rolling guide rail, which can be conveniently moved along the left and right (X) directions, the up and down (Y) directions, and the longitudinal (Z) direction of human body, so the focus of the patient can be accurately sent to the central position, the positioning bed can also be realized triaxial linkage, the Y shaft is installed with an emergency manual rocker arm device. The utility model is suitable for focusing type therapy apparatus to carry out enveloping radiotherapy for larger focus, which can also be applied to the plesiocurietherapy.
Description
Technical field
This utility model belongs to the medical diagnosis therapeutic equipment, is specifically related to radiocurable patient's focus positioner.
Background technology
Radiotherapy is the important means of oncotherapy.Various teleradiotherapies have and advantage such as need not to operate on, patient's misery is little, easy to use, have obtained extensive use.When implementing teleradiotherapy, the patient generally puts the position outside therapy apparatus, by location bed the patient is sent into the treatment chamber again, and the location focus could be implemented radiotherapy then to centers such as therapy apparatuss.Therefore the positioning accuracy of focus directly affects therapeutic effect.The location bed of existing theratron is generally one dimension or two dimension, gamma knife treatment bed as the head that Sweden ELEKTA company produces, fixedly Z is to motor below the surface layer, and by ball line bar and linear rolling track transmission, therapeutic bed can only vertically move or move up and down along human body.By patient front and back or move left and right on therapeutic bed, adjust the health target spot during treatment pendulum position to being fit to the position.This pendulum position mode is loaded down with trivial details, positioning accuracy is poor.Particularly,, need carry out many focuses and repeatedly shine if gross tumor volume is bigger to focusing therapy apparatus, the pendulum position very trouble that just seems like this, precision is difficult to guarantee that the design of treatment plan is also very complicated.
Summary of the invention
The 3 d locating couch that this utility model provides solves three-dimensional pendulum position and the orientation problem of patient when radiotherapy, realize patient's focus accurately location and focusing theratron focus are carried out the envelope irradiation treatment to focus greatly automatically.
3 d locating couch of the present utility model, facing surface is equipped with slideway, and fixed Z connects the Z shaft ball screw to motor below the surface layer, and the bottom is a pedestal, and location bed is moved by computer control, it is characterized in that:
(5) be provided with middle level and lower floor between surface layer and the pedestal, middle laminar surface respectively fixedly Z to nut and Z to linear rolling track, Z constitutes kinematic pair to nut and Z shaft ball screw, fixed X connects the X-axis ball screw to motor below the middle level;
(6) down laminar surface respectively fixedly X to nut and X to linear rolling track, X constitutes kinematic pair to nut and X-axis ball screw;
(7) connected by shear shank between lower floor and the pedestal, the Y that is fixed in pedestal is to the motor worm type of reduction gearing that is in transmission connection, and the latter and the Y that is fixed on the shear shank constitute kinematic pair to nut;
(8) by computer control X, Y, Z axle driver, they are electrically connected to motor with X, Y, Z respectively.
Described 3 d locating couch, it is further characterized in that: Z is connected by shaft coupling with the Z shaft ball screw to motor; X is in transmission connection to step motor shaft and synchronous pulley driving shaft, and the synchronous pulley driven pulley is connected with the X-axis ball screw; Y connects worm type of reduction gearing to motor by worm set.
Described 3 d locating couch can be fixed with the hand-operated rocker arm device on the pedestal, and the hand-operated rocker arm device is by gear or the synchronous pulley worm type of reduction gearing that is in transmission connection.
Linear rolling track is adopted in the motion of each layer of this utility model supporting, has the motion good rigidly, and the transmitting movement characteristic of accurate by the motion of computer control location bed, the center such as accurately sends to patient's focus.Location bed also can be carried out three-shaft linkage, realizes focusing therapy apparatus conformal radiation therapy.Y-axis also is equipped with the urgent hand-operated rocker arm device of a cover, in case fortuitous events such as energising, accident occur, operator can manually reduce to safe altitude with location bed rapidly.
This utility model can be realized the full-automatic high precision location of patient's focus easily.The patient treatment position only needs repeated positioning get final product with to make CT/MRI machine when scanning position consistent after the one-time positioning, the location is convenient, reliably.The present invention is fit to especially realize that focusing theratron focus to carrying out the envelope irradiation treatment than big focus, also can be applicable to the conformal radiation therapy of focusing therapy apparatus, is applied on the full length gamma cutter, has obtained good effect.
Description of drawings
Fig. 1 is this utility model front schematic view,
Fig. 2 is the left view of Fig. 1.
The specific embodiment further specifies this utility model in conjunction with Fig. 1 and Fig. 2.
Among the figure 1 be X to motor, 2 be X to shaft ball screw, 3 hand-operated rocker arm devices, 4 lower floors, 5 is that X is to linear rolling track, 6 middle levels, 7 surface layers, 8 shear shanks, 9 is that Y is to motor, 10 worm type of reduction gearings, 11 is the Z shaft ball screw, 12 be Z to motor, 13 pedestals.
The motor control of 3 d locating couch is finished by the motion-control module of SLC500 series module formula PLC, adopts three motion-control modules altogether.Employing has the three-dimensional couch motion of high-performance step motor drive of segmentation, smoothing function and position feedback, has both guaranteed that 3 d locating couch precision and locating speed require, simplify mechanical mechanism, can avoid servosystem again because fault causes runaway accident.
