Description
Technical field
The utility model relates to technical field of medical equipment, in particular to a kind of electric wire at the uniform velocity rotary irradiation whole skin
The auxiliary device of cancer.
Background technique
Electric wire total skin irradiation (TSEI) technology is one of the main means for treating whole skin canceration.It is to pass through
The electric wire that clinac generates, is irradiated the whole skin of patient.In order to guarantee curative effect, which suffers from
Person keeps same or several identical postures, so that whole skin is sufficiently exposed to electric wire in each treatment for a long time
Irradiation field in, to obtain relatively uniform therapeutic dose.
Currently, implementing TSEI technology mainly uses two ways: fixed angle irradiation and rotary irradiation.Wherein fixed angle
Radiation modality be by putting position, by the posture of patient towards different angle (such as: 0 °, 60 °, 120 °, 180 °, 240 °, 300 °
Deng), allow the skin of different direction to be exposed in irradiation field, still, this radiation modality has the disadvantage that (1) works
Efficiency is very low, time-consuming.In each treatment, needs radiation therapist to enter treatment computer room repeatedly, pendulum position is carried out to each angle,
Than relatively time-consuming.(2) poor repeatability of position is put.Patient over the course for the treatment of, needs to determine power by itself, keeps different angles for a long time
The posture of degree inevitably will appear some posture deviations in this way, causes the exposure dosage of skin that expected requirement is not achieved, influences to treat
Effect.(3) treatment cycle is long.Fixed angle radiation modality takes the mode of radiotherapy every other day, and two treatments just complete a gradation
Dosage, so that entire treatment cycle is long, Low patient is difficult to adhere to treating latter stage.
Rotary irradiation mode is on the device at the uniform velocity rotating at patient station at one, and patient protects for a long time in each treatment
An identical posture is held, until treatment end.For fixed angle radiation modality, rotary irradiation mode does not have
The Concept of Angle of posture direction does not need the angle that patient is put to certain fixations, and working efficiency greatly improves, treatment cycle
Short half, seance can complete the dosage of a gradation, and still, there is also some disadvantages:
1, the constitution of patient is more demanding, and there are medical security risks.During rotary irradiation, patient is constantly in even
Fast rotation status keeps some posture by itself determining power for a long time, there is higher difficulty if not supporting the auxiliary tool of body
Degree, can inevitably change posture, result will cause dose deviations, and expected effect is not achieved.In addition, the trouble weaker for constitution
For person, it is easy to appear syncope, or even fall, it is serious to will cause malpractice.According to statistics, most of whole skin cancer is suffered from
The constitution of person is weaker, most also to die down in treatment latter stage even the patient that constitution is strong.
2, in-plane scatter screen changes at a distance from patient with rotation angle change.Current in-plane scatter screen stands on patient
Front, when rotated, body constantly changes patient at a distance from in-plane scatter screen, cause patient absorb ray dosage rate
Constantly variation, is unfavorable for obtaining relatively uniform therapeutic dose.

For the motor for being connected to the second rotating disk top, and the rotation center line overlap of the first rotating disk 13 and the second rotating disk.The
A column is extended downwardly among the bottom of two rotating disks, the bottom end of column is connected to the middle position of transverse bar 23, laterally
The both ends of bar 23, which are hung, is provided with several arm sleeves 24, in order to the more steady arm for tangling patient, the one of transverse bar 23
End hangs arm sleeve 24 by four ropes 25, and the arm of patient penetrates and realizes fixation in arm sleeve 24, and the top of rope 25 connects
It is connected to hook 26, hook 26 hangs on transverse bar 23 and can transversely bar 23 horizontally slip, to adapt to the trouble of different arm lengths
Person.Meanwhile the adjustable in length of rope 25, the length adjustment of rope 25 can be realized using the adjustment structure of school bag strip length,
To adapt to the patient of different height.When patient stand receives electron beam irradiation, the hand of patient can elevate and grip in transverse bar
On 23, the burden of patient is equally alleviated.The bottom symmetrical of transverse bar 23 is set there are two handgrip, is firmly grasped laterally to increase patient
The comfort level of bar 23.Wherein, arm sleeve 24 is made of cloth material, and cloth material will not generate decaying to electric wire.
Be provided with arc-shaped diffuser screen 16 between bottom platform 11 and top platform 21, diffuser screen 16 in vertically arranged,
The electric wire generated from linear accelerator is scattered that screen 16 is launched and converged to the rotation center of the first rotating disk 13, just
It is radiated at the patient at 13 center of the first rotating disk.
When carrying out electron beam irradiation using the device, the posture that sitting can be used in patient is realized the irradiation of the upper part of the body and is adopted
The irradiation that the lower part of the body is realized with the posture of standing, reduces the stand up time of patient's half, significantly reduces the burden of patient.?
In irradiation process, the hand of patient can realize suspension by arm sleeve 24 or grab surely on transverse bar 23, and trouble is greatly saved

Preferably, setting is easy to implement the same patient's there are two moulding vacuum bag is hardened in the first rotating disk 13
Precisely with comfortable erect-position, when guaranteeing to receive electron beam irradiation every time, patient is able to maintain the same posture substantially.Though current turntable
So there is fixed footprint guidance patient stand, but this fixation, single footprint are not able to satisfy all patients.For individual
The patient of change, interpersonal sole shape size is indefinite, and someone is knock-knee, and someone is outer octal, foot side when standing
Position difference, if being easy to appear the error of stance if being used uniformly fixed, single footprint guidance patient stand,
Projected dose may be not achieved in the dosage that patient receives, and affect the treatment.In addition, if patient over the course for the treatment of, is in for a long time
Uncomfortable erect-position will increase the sense of discomfort of patient, is easy to generate treatment the mood of dislike, equally will affect curative effect.
Preferably, linear accelerator is connected with control switch and controller, motor is connect with controller.Controller is being controlled
While linear accelerator processed generates electric wire, control motor synchronous rotation, i.e. linear accelerator generates electric wire and rotating dress
Synchronous operation is set, effectively avoids occurring shortcoming dosage or excessively high overlapping dosage with patient, and then influence curative effect.
Preferably, the first rotating disk 13 is equipped with danger button, danger button is connect with controller.If patient is treating
It is uncomfortable in the process, think pause treatment, it is only necessary to trigger emergency switch, controller, that is, controllable motor and linear accelerator with foot
It stops working.
Preferably, the first rotating disk 13 is provided with pointer, angle index line is provided on the first outer disc 12.Due to electricity
Sub-line rotary irradiation mode does not have the Concept of Angle of posture direction, when patient over the course for the treatment of because of certain reason caused by treatment
It is disconnected, after Resolving probiems, if thinking if then treating, to guarantee that dosage is accurate, it need to be completed since the rotation angle of pause
Remaining exposure dose.Angle pointed by pointer can be first by pointer regulation when being again started up when interrupting treatment by the last time
The angle being directed toward to the last time, continual cure easily accurately complete linking.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
