The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments this utility model is described in detail.
A kind of ray blocks equipment, comprising: guard mechanism comprises: be used for absorbing the block of ray, described block comprises that one is used for receiving the work surface of ray; Be used for driving the reciprocating elevating mechanism of described block; For the opener that described guard mechanism is moved between at least two operating positions, wherein in first operating position, described work surface is in first state; In second operating position, described work surface is in second state.
Specifically, the ray guard mechanism in this utility model mainly comprises two parts: guard mechanism and opener.Guard mechanism comprises block and elevating mechanism.Elevating mechanism be used for to drive the block motion, makes block be adjusted to a reasonably height, lies low therapeutic bed above block when treating the patient, so that block absorbs ray.Opener is connected with guard mechanism, opens or pack up guard mechanism.Opener makes guard mechanism be in and is no less than two operating positions by making the guard mechanism action.When guard mechanism was in first operating position, the work surface of guard mechanism block was in first state.When guard mechanism was in second operating position, the work surface of guard mechanism block was in second state.By the driving of opener, the work surface of guard mechanism block can be adjusted, and different environments for use is provided.When guard mechanism was in second operating position, the patient can receive whole body radiotherapy or the ray guard mechanism is in off position.This utility model ray guard mechanism can to substitute original thick and heavy therapeutic room's wall, can be packed up guard mechanism with through the radiation absorption behind the patient body obsolete the time.Thereby both reduced occupation space, the capital construction cost that also reduces hospital and building requirements to the accelerator therapy chamber.
With reference to shown in Figure 1, ray blocks equipment and comprises: guard mechanism 1, opener 2 and bindiny mechanism 3.
Guard mechanism 1 comprises block 101 and elevating mechanism.What the block 101 among this utility model embodiment adopted is that lead is made, and lead material density is big, for the good absorbing effect of ray.Elevating mechanism is used for carrying block 101, and drives block 101 reciprocating motions.
Wherein elevating mechanism comprises: lifting platform 102 and lifting motor 103.What lifting platform 102 adopted is a kind of bearing-type lifting platform.When not using, lifting platform 102 can fold, to reduce occupation space; In use, lifting platform 102 can be under the driving of lifting motor 103, the height that rises or descend and set.Block 101 is placed on the lifting platform 102, and lifting platform 102 carrying blocks 101 move back and forth.Like this, just make things convenient for mechanism when in use, regulate the height of block 101 on the lifting platform 102 by the work of control lifting motor 103.Guard mechanism also comprises: shell 104 is used for holding block 101 and elevating mechanism.Block 101 and elevating mechanism are accommodated in shell 104 the insides, and install and fix with shell 104.Like this, lifting platform 102, block 101 and lifting motor 103 just are fixed to an integral body, under the drive of shell 104, can realize the action of guard mechanism 1 integral body and the change of position.Shell 104 is hinged by fixed axis 401 and supporting seat 402, and shell 104 rotates around supporting seat 402 under the drive of fixed axis 401.Like this, opener 2 is by driving the motion of fixed axis 401, just can so that whole guard mechanism 1 realize around supporting seat 402 rotations.
The two ends of fixed axis 401 are separately installed with supporting seat 402, and described supporting seat 402 fixes with the shell 104 of linear accelerator, and like this, supporting seat 402 plays by fixed axis 401 and supports fixed housing 104 and drive the effect that shell 104 rotates.
The action relationships of each parts that ray of the present utility model blocks equipment is as follows.
The slide rail 202 of opener 2 is vertically placed, and opens motor 201 and drives counterweight 203 knee-action on slide rail 202.Open motor 201 end motion that makes progress along the lower end of institute's lifting sliding rail 202, opener 2 becomes second state by first state.
With reference to shown in Figure 2, when opener 2 was in first state, guard mechanism 1 was in collapsed state.
Along with opener 2 by first state in the change procedure of second state, first connector 301 that is connected with the counterweight 203 of opener 2 can rise along with the motion of opener 2.The motion that makes progress of first connector 301 drives the motion of the second hinged connector 302 with it.Since following fixing of supporting seat 402, fixed axis 401 rotational motion on supporting seat 402.So whole guard mechanism 1 is that rotating shaft is rotated counterclockwise action with fixed axis 401 under the effect of second connector 402, the duty that is horizontal until guard mechanism 1.
With reference to shown in Figure 1, it is in running order that ray blocks equipment.Before radiotherapy began, block 101 upper surfaces were apart from radiotherapy isocenter point 550mm.The patient lies low on the therapeutic bed above block 101, begins radiotherapy then.Promote block 101 by lifting motor 103 then and rise to apart from isocenter point 300mm, radiotherapy begins.In the radiotherapy process, lead block 101 can absorb through the ray behind the patient body, directly is radiated therapeutic room's metope and floor to prevent ray, prevents that ray from causing radiation pollution to external world thereby substitute original thick and heavy therapeutic room's wall.After radiotherapy finishes or patient when accepting whole body therapeutic, promote blocks 101 by lifting motor 103 and drop to apart from isocenter point 550mm.Open motor 201 actions, by bindiny mechanism 3 counterweight 203 is moved upward, guard mechanism 1 is packed up from second state becomes first state shown in Figure 2.
This utility model also provides a kind of linear accelerator, comprises that above-mentioned ray blocks equipment.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not breaking away under the principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
