One end of the variable diameter baffle is actively connected with the front turntable surface; grooves with corresponding quantity of the variable diameter baffle are arranged on the front surface of the annular turntable, the axes or the extension lines of the axes and the tangents at the intersections of the inner periphery on the annular turntable form similar acute angles; a slide bar corresponding to the grooves is fixed on the same position on the surface where the front turntable surface of the variable diameter baffle is corresponding to the annular turntable; one end corresponding to the end where the variable diameter baffle is actively connected with the front surface of the annular turntable is folded on the adjacent variable diameter baffle; the turntable driving mechanism comprises a worm or a gear, which cooperates with a plurality of skewed teeth on the outer periphery of the annular turntable by screw threads of the worm; when the worm rotates clockwise or counterclockwise, the turntable driving mechanism drives the annular turntable to rotate clockwise or counterclockwise, or cooperates with a plurality of commutating teeth on the outer periphery of the annular turntable by the gear.
Description
Technical field
The present invention relates to ultrasound tumor therapeutic system, be specifically related to a kind of ultrasonic tumor treating system hole reducing device.
Background technology
Along with the development of ultrasonic therapeutic technology, imaging devices such as ultrasonic combined B ultrasonic device detect the treatment tumor and have also obtained significant progress.In existing ultrasonic therapeutic process, all can be fixed on patient on the therapeutic bed usually with a cover position fixture.And then the tumor before treating is positioned and observes, and gather corresponding lesion image with imaging devices such as B ultrasonic.B ultrasonic scanning obtains focus before the image acquisition, after the image acquisition, carries out layering and handles back formation figure layer.On gather good image, carry out cropping cloth target, define the position and the energy parameter that each point are carried out ultrasonic therapy, fill the focus zone that needs emitting treatment with target spot, the focus zone is the approximate range of the focus sketched the contours of of doctor." target spot " is the size in institute coking territory after a ultrasonic emitting focuses on." image-region " then is meant the B ultrasonic image that collects on " figure layer ".Repeat the process of this cloth target, finish up to the whole cropping cloth of the figure layer target that all are gathered.Treat at last according to the planning emission ultrasound wave that configures, during treatment, system in layer read data.At first take out a figure layer, obtain the position of a target spot then, in three dimensions, move the treatment head to the position that target spot configures.The energy emission ultrasound wave of setting during then according to planning is finished the treatment of a target spot.Repeat above process, finish whole therapeutic scheme.And in this whole therapeutic process, patient's position is that requirement remains on an immobilized state always, and the point that could guarantee emission is consistent with the three-dimensional position of the point that planning the time is arranged.
Treatment mouth on the energy focusing ultrasonic-high tumor treating system bed of prior art is the circular port of a fixing straight warp, and diameter generally is about 300mm.The size of the diameter of circular port had not only affected needs that the treatment head moves in the therapeutic process but also the level of comfort that influences the patient.The circular port diameter is less than normal, and ultrasound tumor therapeutic system is difficult to satisfy different patients, and the treatment of different parts focus on the treatment path, produces and interferes.The circular port diameter is excessive, in the time of can making the patient prostrate again, feels bad especially, and the same posture when being difficult to keep planning in treatment time influences therapeutic effect.
