Description

Surgical operation table with stereoscopic directional radiation apparatus

The present invention relates to a kind of stereotaxic radiosurgery operating-table that is applied to radiate neurosurgery, specifically wait central line accelerator operating-table.

At present along with the priority of large-scale advanced neuroimaging instruments such as the heavy cerebral angiography DSA of CT, MRI is come out, a new branch of science--stereo directional radiative neurosurgery has appearred, it is after utilizing the stereotaxis instrument with god footpath image central nervous system disease accurately to be located, reboot heavy dose of high-energy physics ray once circumscribed or shine several times the location target spot on, make no matter good pernicious group of trifoliate orange all is subjected to destroying the purpose that is issued to treatment in the situation of not opening craniocerebral operations in this target area.Concrete implement this operation be use r one cutter, proton cutter and etc. the central line accelerator, r one cutter involves great expense, auxiliary facilities, the house complicated condition, the every 5--10 of radioactive source changes once, makes it to use limited.Huge more being difficult to of proton cutter equipment popularized.And etc. the central line accelerator be on the basis of original linear accelerator, to be equipped with stereotactic apparatus and collimator can be worked.But at present the collimator that uses generally is exactly that former stereotype central authorities open hole, a garden, connect on accelerator, be difficult for when ray passes like this concentrating, easily produce scattering, and former stereotype change also inconvenient because beam is thicker, not high to positioning accuracy request, can undergo surgery so need not position finder, this operation is because the dosage of high-energy physics ray is very big, and the result is made the benign tissue in the target area also be destroyed in malignant tissue when destroying.And existing position finder all designs at brain acupuncture operation, can't be used to radiate neurosurgery.

The purpose of this invention is to provide a kind of stereotaxic radiosurgery operating table device.This device be a kind of can be after standard be handled with the high-energy rays bundle, the wire harness that under the stereotactic apparatus guiding, strictness is limited, the directive intracranial tumor on vascular malformation focus or some the damage position, is realized the instrument of no wound stereo directional radiative neurosurgery exactly.

Stereotaxic radiosurgery operating-table of the present invention is by adapter, adapter bed, focus location-plate, cranium fixed coordinates frame, multiple aperture collimator, electron linear accelerator.The rotation accelerator, parts such as CT scan machine constitute, and from the radiation beams of the 8-16 million electro-volt of electron linear accelerator, handle center Ye Chu such as directive through collimator.Handle by CT machine tomoscan image and to find out the intracranial lesion point, and intercept out the D coordinates value of focus point from being fixed on adapter on the patient's skull and frame of axes and location-plate.By D coordinates value with patient's focus point place accelerator etc. center Ye Chu, make both pole registration accuracies be not less than+1.5 millimeters.The rotation accelerator head cooperates the rotation of bed pedestal, is focus point along the skull top with the focus point, walks around the encephalic operation forbidden zone and does multi sphere mark radiosurgery, makes focus point place tissue produce irreversible radiation reaction.

Advantage of the present invention is: 1, because collimator adopts the lead structure, make wire harness more concentrated, reduced scattering phenomenon effectively, and lead can be made into different apertures, the replacing convenience.But, make through the thin beam of collimator lead accurately to shine on the target spot of location 2, by regulating collimator and position finder precision location.Simultaneously therapeutic process can divide irradiation several times, each irradiation can by regulate the orientation make ray from different angular illumination to target, to reduce infringement to benign tissue.3, position finder not only can be used for the radiosurgery orientation, and it is directed also to can be used for the operation of acupuncture brain, has increased the function of operating-table.

Be further described below in conjunction with the structure of accompanying drawing stereotaxic radiosurgery operating-table of the present invention.
