Abstract
The utility model relates to a radiotherapy positioning device for a skull tumour. A patient skull is fixed on a rectangular base with a U-shaped pillow on the basis of three-dimensional conformality, the cross section and the sagittal surface of a tumour in a patient skull can be accurately positioned due to the adoption of a hand-shaking threaded lifting rod, the operation is convenient and safe, and a vernier scale is used to detect the position of the tumour in the skull to further ensure the accurate positioning of the tumour in the skull. Compared with a CT simulated positioner, the device has the advantages of flexible movement, low cost, economy and practicability.
Description
Affiliated technical field
Head tumor radiotherapy positioner on the design clinical medicine, purpose are accuracy and repeatability when improving intracranial tumor pendulum position.
Background technology
Skull tumors is a kinds of tumor, and about 80～90% postoperatives of skull tumors patient need carry out radiotherapy, and this has just emphasized the accuracy of tumor throwing according to the position, has mistake will damage normal cerebral tissue slightly.Along with updating of radiotherapy apparatus today, the appearance of accurate radiotherapy technology, make skull tumors under CT simulation location, very accurately diseased region is treated through treatment planning systems (TPS), but these equipment price costlinesses, concerning we had the country of 1,300,000,000 populations like this, universal use is difficulty relatively, and traditional ocular estimate accuracy and poor repeatability.
Summary of the invention
Carry out the skull tumors postoperation radiotherapy at the city-level that does not have CT analog machine and TPS system and county, town hospital, can't guarantee the accuracy and the repeatability of position, developed skull tumors radiotherapy localization device with conventional ocular estimate location.
This positioner technical scheme is: with a band U-shaped pillow base, be used for fixing the tumour patient head, making support (lifting arm) with the screw thread thick steel pipe is fixed on the base, again hand lifting screw is fixed on the lifting arm, the square frame of vernier cursor is fixed on the lifting screw, make the square frame of band vernier cursor move up and down, to guarantee safety and the accuracy in clinical practice with the big I of head.Vernier cursor is divided into X-axis and Y-axis both direction, guarantees the accurate positioning of intracranial tumor on cross section and sagittal plane.The basic goal of tumor radiotherapy is to the enough accurate treatment dosage of tumor region, and makes normal surrounding tissue and the few exposure damage of organ, to improve the local control rate of tumor, reduces the irradiation complication of normal structure.And the formulation of treatment plan, the accuracy of determining knub position is crucial.
Radiotherapy locating device for skull tumors is easy to use, accurate positioning, economical and practical, be suitable for having radiotherapy equipment not have the hospital of TPS system with independent simulated positioner, the principle of simulated positioner is equivalent to X line perspective, normal cerebral tissue and tumor tissues are difficult to differentiate on simulated positioner, after the imaging of CT analog machine must be arranged, delineating out the knub position that needs accurately through the TPS system.
Description of drawings
Below in conjunction with accompanying drawing radiotherapy locating device for skull tumors is further specified.
Fig. 1 is the radiotherapy locating device for skull tumors side view.
Fig. 2 is the radiotherapy locating device for skull tumors vertical view.
1 base 2U shape rests the head on 3 lifting arms, 4 lifting arms and hand lifting screw is connected and fixed device 5 hadle dish 6 hadles, 7 square boom 8 pull-type points position bar 9 screw thread elevating lever 10 carrying handles, 11 tape character color cutter head 12 cranes and base is connected and fixed device 13 band vernier cursor square frame 14Y axle vernier cursor 15X axle vernier cursors 16 basis cranii line positioning rules
The specific embodiment
1, to have before the art and postoperative imaging examination sheet.
2, allow patient lie on one's side on positioning pillow, both arms are put the health both sides naturally.
3, according to the change of preoperative and postoperative image sheet knub position, find out focus.
4, measure the position of tumor on the three-dimensional of intracranial, promptly horizontal shape face, sagittal plane, coronalplane.
5, hand lifting screw is reduced to basis cranii line positioning rule and be attached to scalp, at this moment, that X-axis and basis cranii horizontal line is overlapping, see numeral on the Y-axis, upwards move to the cross section knub position that image sheet upside amount arrives, mention a position bar and fall tape character color cutter head, on scalp, leave marks.See numeral on the X-axis again, vernier cursor is mentioned a position bar and is fallen tape character color cutter head to the sagittal plane knub position that image sheet upside amount arrives on the mobile X-axis, leaves marks on scalp.Individual cross point, i.e. knub position are so just arranged on scalp.
Claims (3)
1. radiotherapy locating device for skull tumors is characterized in that: immobilized patients head on the base of band U-shaped pillow, use vernier cursor to measure intracranial position, tumor place.
2. according to the described radiotherapy locating device for skull tumors of claim 1, it is characterized in that: vernier cursor is divided into X-axis and Y-axis both direction, is used for determining the position of joint on cross section and the sagittal plane.
3. radiotherapy locating device for skull tumors according to claim 1 is characterized in that a pull-type point position of vernier cursor band bar on the X-axis, when demonstrating the tumor position on the vernier cursor, with bar location, some position.
