Abstract

A location and swinging frame used for the tumour chemotherapy is composed of a left side plate, a right side plate, a front-end plate and a back-end plate. The upside of the front-end plate is arranged with a scale mark for the laser identification and the swinging of the Z coordinate. The left side plate is also arranged with the scale mark for the laser identification and the swinging of X and Y coordinates. The top of the location and swinging frame is fixed horizontally with three marker poles which are supplied for CT scanning and identification and being as location coordinates. Two marker poles are parallel and another marker pole is crossed with the other two. The left side of the location and swinging frame is arranged with two marker poles which are arranged for the CT scanning and identification and being as location coordinates. One marker pole is parallel to the top two marker poles and arranged in a different vertical plane. The utility model sets up CT imaging coordinates and confirms the center of the tumour by marker poles; and sets up laser swinging coordinates by the scale mark to place the center of the tumour in the center of a therapeutic machine, then the effect of the precise chemotherapy can be attained.

Description

The fixed pendulum position framework that is used for tumor radiotherapy

One, technical field

This utility model relates to the tumour radiotherapy apparatus, is specifically to be used for the framework that the tumor radiotherapy process is correct, cervical region plays the location and the pendulum position acts on.

Two, background technology

In tumor accurate radiotherapy process, must patient's tumor be positioned, promptly generally by means of framework, utilize CT scan in CT shadow rubber chamber, determine tumor shape, profile and tumor center, and dosage is carved in the corresponding irradiation by transmitted intensity and irradiation time decision that accurately calculates a certain zone of concrete tumor.If the exposure dose deficiency then is not enough to kill cancer cell,, can injure normal cell tissue and organ again if exposure dose is excessive.After this, utilize therapy apparatus to carry out radiotherapy, and the precondition of implementing accurate radiotherapy is, must realize accurate repeated positioning in therapeutic room, be about to tumor center place exactly therapy apparatus etc. on the center, to carry out isocentric treatment.Existing positioning framework is separated with pendulum position framework, and the design of positioning framework does not consider to put the requirement of position.For accurate repeated positioning brings difficulty and obstacle.

Three, utility model content

The purpose of this utility model provides a kind of fixed pendulum position framework that is used for tumor radiotherapy that has location and repeated positioning effect concurrently.

This novel purpose is achieved in that a kind of fixed pendulum position framework that is used for tumor radiotherapy, mainly connect and compose framework by left and right side plate and forward and backward end plate, the front end-plate top of framework is provided with for laser identification, as the graduation mark of putting position Z coordinate, and left plate is provided with for laser identification, as the graduation mark of putting position X and Y coordinate; Frame roof flatly is fixed with for CT scan identification, as three marking rods of the elements of a fix, and wherein two marking rods are parallel to each other, and another marking rod is positioned on the crossing position of parallel marking rod with two; Also be provided with two marking rods that are intersection location for CT scan identification, as the elements of a fix, mutually on the frame left face, the one marking rod is parallel to two parallel marking rods of frame roof, and is positioned at different perpendiculars with it.

This device is for being attached to an external frame structure that has three-dimensional system of coordinate of patient.Wherein, three marking rods in horizontal plane of frame roof and two marking rods on the survey face of a framework left side are formed the CT coordinate systems in image: can adopt measure to determine that arbitrary amount is with respect to the locus of this coordinate system in the CT scan scope, thus, can obtain tumor center is the pinwheel coordinate; Secondly, by two graduation marks of the representative X on the left plate, Y coordinate and the graduation mark of the representative Z coordinate on the front end-plate, form the coordinate system of the accurate repeated positioning of laser.

During use, patient's incidence is fixed in this novel frame (frame fixation is on therapeutic bed), at CT Room, uses CT scan, determines the space coordinates of tumor center with respect to the CT coordinate systems in image; Again in therapeutic room, by therapeutic room's medial surface laser (be preferably both sides laser, the respective frame both sides all are provided with pendulum position coordinate scale line) and top lasers indication, carry out coordinate transform, with tumor center place therapy apparatus etc. the center, realize accurate repeated positioning, carried out isocentric treatment.Thereby two functions of this novel integrated location and pendulum position have been made condition for isocentric treatment, for accurate radiotherapy.

Fig. 1 shows the front view that this is novel;

Fig. 2 Fig. 3 is respectively left view and the vertical view of Fig. 1;

Fig. 4 is a shown in Figure 1 novel axonometric chart.

Five, the specific embodiment

Fig. 4 illustrates, and framework is connected and composed by left plate 7, right plate 4 and front end-plate 1, end plate 2.Referring to Fig. 1, front end-plate 1 top of framework is provided with for laser identification, as the graduation mark 1a that puts position Z coordinate, be provided with equally on the end plate 2 for laser identification, as pendulum position Z coordinate another graduation mark identical with graduation mark 1a, for the top laser irradiation in the therapeutic room, thereby determine space coordinates.

Among Fig. 2, frame left plate 7 is provided with for laser identification, as the graduation mark 7a, the 7b that put position X and Y coordinate; Referring to Fig. 3, frame roof flatly is fixed with for CT scan identification, is parallel to each other as marking rod 10,11,12, two marking rods 10,12 of the elements of a fix, and another marking rod 11 is positioned on the position that two marking rods 10,12 intersect; Also be provided with on the left surface of framework for CT scan identification, as the marking rod 8,9 of the elements of a fix, marking rod 9 is parallel with marking rod 10,12, and is positioned at different perpendiculars with it, and marking rod 8 intersects with marking rod 9.

Also be provided with symmetric other two graduation mark (not shown)s on the right plate 4 of said frame with graduation mark 7a, the 7b of left plate.

The end plate top of said frame is provided with for laser identification, as a pendulum position Z coordinate, another graduation mark (not shown) identical with graduation mark 1a.The right flank of framework be provided with for CT scan identification, as the elements of a fix, with marking rod 8,9 symmetric other two marking rod (not shown)s.

Have a plurality of jack 7c on the above-mentioned left plate, jack by level and vertical direction in a row, become the row setting; Also have when use insertion jack, make the dipstick 13 that graduation mark was used, had on it in auxiliary fixed pendulum position.

Also be provided with on the right plate 4 with left plate on jack 7c jack and the dipstick identical with dipstick 13.Dipstick mainly plays auxiliary fixed pendulum position usefulness, and dipstick inserts from a jack when touching patient body, and this jack promptly to an X, Y coordinate should be arranged, is added the degree of depth reading on the dark chi of side, i.e. Z coordinate can be determined the space coordinates of a certain position of patient's body surface.
