Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of thoracic cavity radiotherapy is solid with vacuum pad joint thermoplastic body film
Determine device.
Background technique
With the fast development of computer technology, image technology and radiotherapy apparatus, the radiotherapy of tumour enters accurate positioning, essence
Really plan, accurate radiotherapy epoch, thorax and abdomen malignant patient is highly prone to itself anatomical features in Patients During Radiotherapy, and (such as abdomen formula is exhaled
Suction, heartbeat, skin drawing, weight, subcutaneous fat thickness etc.) influence, there are larger for the technique for fixing of radiotherapy position
Difficulty, pendulum position repeatability it is relatively poor.Therefore, Postural immobilization technology is rationally applied, raising pendulum position accuracy, which becomes, accurately puts
The important prerequisite and guarantee for the treatment of.
Tumor radiotherapy is a longer process, and patient carries out that the treatment of pendulum position is repeated several times, and Postural immobilization technology is
Guarantee radiotherapy accuracy key factor, especially thorax and abdomen malignant patient, position is influenced by multifactor, is selected suitable solid
Determining technology is particularly important.Thermoplastic body film technique for fixing and vacuum pad fixation can effectively improve pelvic cavity to studies in China as the result is shown
The pendulum position accuracy of portion and abdominal tumor patient over the course for the treatment of.Using simple vacuum pad fixation postures, patient is due to abdomen formula
The influence of the factors such as breathing, heartbeat, meal situation and skin drawing, up-down error is especially big during putting position, and patient
Skin-marker is smudgy because of perspiration, needs often to mend line, to cause artificial Set-up errors；It is fixed using mere body film
Position, the contacts baseplate that patient's skin of back cannot sufficiently with fixed body film, can make the body of patient while buckling body film
Rotation phenomenon is caused, causes left and right Set-up errors big；Using vacuum pad+body film immobilized patients, the back and two sides of patient body
Soft tissue can be come into full contact with vacuum pad without movement, and upper limb, head and lower limb are obtained suitably supporting and be fixed, and are being irradiated
Position remains unchanged in journey, not only protects normal surrounding tissue and organ, and the dosage of target area is further increased and
The dosage of normal surrounding tissue is substantially reduced, and reaches the good result of radiotherapy, thus should be clinically worthy of popularization.
Summary of the invention
For the above technical problems, comfortable, fixed reproducible, treatment that the present invention provides a kind of patient body positions
