Description

3 D stereo packaged type therapeutic bed

Technical field

This utility model relates to a kind of packaged type 3 D stereo locating therapy bed.It is mainly used in carrying out as the focus point to the patient in the medical image field the accurate convenient location of 3 D stereo, belongs to the medical image field.

Background technology

Radiotherapy is a kind of to local or regional malignant tumor is effected a radical cure or the means of palliative treatment, the target of its pursuit is to give accurate radiological dose irradiation to knub position of determining and volume, make normal structure around the pathological changes and important internal organs only be subjected to minimum damage simultaneously, guarantee that the cost with minimum obtains the long-term high-quality survival of patient when killing tumor to greatest extent.The radiotherapy location bed of common application generally was fixing or semifixed in the past, and the location also is to orientate the master as with the coordinate system of two dimension, was difficult to the focus point is accomplished accurate three-dimensional localization.Thereby we in conjunction with the medical image technology of latest modern technological, realize that a kind of imaging effect is good, easy to use, applied widely, the medical image positioning equipment of accurate positioning on the basis of the mature technology of using for reference Related product in the past.Can make patient's focus point obtain accurate localization on the one hand, on the other hand, make the patient feel comfortable convenience again.

Summary of the invention

In order to realize accurately locating and make the patient feel comfortable target easily, this utility model has adopted multinomial innovative technology, carried out a series of innovation transformation process at aspects such as device material, Machine Design, processing technology, it at the mature technology of using for reference similar products at home and abroad with combine and put into practice clinical experience and develop, passes through the comprehensive evaluation and the registration of inspection center of State Pharmaceutical Administration and Ministry of Public Health professional institution by Southeast China University's medical image and accurate diagnosis and treatment Engineering Research Center.

The technical scheme that its technical problem that solves this utility model adopts is: packaged type 3 D stereo location bed is made up of ten parts.Body 3 D stereo positioning framework, the resetting instrument, body index point elements of a fix corrective system, three-dimensional space coordinate system, CT scan positioner, slidingtype location headrest, negative pressure bag navigation system, balance correction rigidly fix frame, CT and locate adaption system and other and be fixed on successively on the base plate of location bed as some accessories such as fixing bellybands, by adopting 5 point location methods, set up the 3 D stereo coordinate system, can accurately orient the focus point.

Body 3 D stereo positioning framework mainly is made up of positioning pedestal and connection seat, railroad shoe, and pedestal adopts the macromolecule carbon cellulose fiber to be made through special process; When both sides have two bellybands to limit patient at the bottom of the connection seat owing to respiratory movement causes the free deviation of internal organs, and the concordance during resetting can guarantee interval procedure the time, railroad shoe can make bridge support move freely, enlarge area for treatment.The resetting instrument comprises that bridge support, rail plate are adaptive, gauge point, correction fine measuring instrument, the special lock rack device of macromolecule, position indicator, bridge support is removable, and patient's position repeatability can be proofreaied and correct by resetting instrument and body index point resetting system.Body index point positioning correcting system comprises to be proofreaied and correct die sleeve and proofreaies and correct fine measuring instrument, by establishing coordinate reference and do the accuracy that sign is finished patient's repeatedly resetting on patient's body skin.The space multistory coordinate system comprise X to center, form coordinatometer, Y to staged coordinatometer, Z to the fixed-point type coordinatometer, in the body positioning framework both sides and the connection seat outside, post two scales (Z scale), two positive negative direction X scales are arranged on crane span structure, and the location that step Y scale is finished 3 D stereo is jointly posted in the crane span structure outside.The CT scan navigation system comprises " Z " type bar, CT scan navigation system, slide rail type CT scan witness marker bar." Z " type bar CT scan navigation system is positioned on the pedestal among the dark brown plate of planar macromolecule, and slide rail type CT scan telltale mark bar is positioned at body witness marker point calibration die sleeve lower plane.Slidingtype location headrest comprises slip locating rack, high molecular polymerization headrest, mobile scale, dismountable type locking device, mainly be when guaranteeing that the patient crouches body pendulum position comfortable with carry out auxiliary location.Negative pressure bag navigation system is mainly used in the location of negative pressure bag, handles by the vacuum forming pad being carried out evacuation, makes that the maintenance large tracts of land contacts between shaping cushion and patient and the body, to obtain accurate resetting.Balance correction has just been tied fixed mount and has been comprised horizontal adjustment instrument and fixture, and the horizontal adjustment instrument can be proofreaied and correct the therapeutic bed base plane with the aid level indicator, guarantees the accurate of space multistory coordinate system; Fixture mainly is for therapeutic bed is fixed on the accelerator therapy bed.CT location adaption system mainly is a high molecular polymerization positioning plate, and base plate is mainly used in the location of 3 D stereo therapeutic bed on the CT scan machine, also can be used for the calibration of 3 D stereo therapeutic bed level on the accelerator simultaneously.When can limiting patient treatment, body positioning and fixing bellyband causes the free deviation of internal organs, the concordance of resetting when the scale on the bellyband can guarantee interval procedure simultaneously owing to respiratory movement.

The use the beneficial effects of the utility model are: five point locations are provided when doing treatment plan by the 3 D stereo positioning coordinate system that uses precision as the clinician, the precision and the direction identity of target position when reaching definite plan with the accurate effect that guarantees CT scan, simultaneously, because the length of locating rod increases greatly, can guarantee a plurality of focus point single passes, many target spots implementing plan to any position of patient's body.In addition, this utility model Energy and comfort, video imaging is effective, is fit to many-sided being used.
