Abstract

The utility model discloses a stereo-oriented device comprises two panels (1) which are vertical with each other and a lateral plate (2), scale (5) is arranged on every side of the two panels, a C T developing pipe (3) and fixation band (4) is respectively arranged on the panels (1) and the lateral plate (2). The utility model has the advantages of reasonable design, convenient to use, and focus can be stereo-oriented conveniently and quickly via the methods of simple geometric calculation and manual operation, stereo-radiation therapy can be achieved under the condition of cost low.

Description

Stereotaxic apparatus

(1) technical field:

This utility model belongs to medical instruments field, and what relate generally to is a kind of Stereotaxic apparatus.

(2) background technology:

At present, clinical when implementing stereotactic irradiation, at first need realize accurately location to patient's lesions position with special-purpose stereotaxis equipment, just can treat then.Because employed stereotaxis equipment manufacturing cost costliness so medical expense is higher, also have certain distance for the medical conditions of present China and the ability to shoulder economically of general patient, thereby many patients can not be benefited from the measure of this treatment.

(3) summary of the invention:

The purpose of this utility model promptly produces thus, and it is simple to propose a kind of structural design, flexible and convenient to use, can realize rapidly and accurately the stereotactic Stereotaxic apparatus of patient's focus under the situation spending less.

For achieving the above object, this utility model is achieved through the following technical solutions: it is mainly developed to manage by panel, side plate and CT and forms, and the mutual vertical fixing of side plate and panel connects, and is equipped with scale on every limit of its two allegro; CT development pipe is separately positioned on panel and the side plate; On panel and side plate, also be respectively equipped with fixing band.

This utility model design is unique, simple in structure.Because it is to utilize simple geometric calculating and manual method directly to make marks at body surface, has omitted existing special-purpose stereotaxis equipment, thereby just can realize the accurate stereotactic purpose of patient's focus under the very low situation of cost.

(4) description of drawings:

Accompanying drawing 1 is this utility model structural representation.

Accompanying drawing 2 is this utility model panel construction sketch map.

Accompanying drawing 3 is this utility model lateral plate structure sketch map.

Accompanying drawing 4 is this utility model user mode sketch map.

(5) specific embodiment:

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

As Figure 1-3: present embodiment is made of panel 1, side plate 2, CT development pipe 3 and fixing band 4.Panel 1 is connected with side plate 2 mutual vertical fixing, is equipped with scale 5 on every limit of this two boards, and panel 1 and side plate 2 adopt lucite to make.CT development pipe 3 is the angle respectively and is arranged on panel 1 and the side plate 2, and its concrete fixed form can be offered groove on panel and side plate, and 3 interlockings of CT development pipe are fixed within it.CT development pipe is filled contrast solution and is made in pipe.Be provided with the plastic foam pad 6 that the body surface arc with human body matches at the connecting portion of panel 1 and side plate 2, its effect is the stability that improves location-plate.Use for convenient, be respectively equipped with horizon rule 7 on panel 1 and the side plate 2.Four fixing bands 4 with adjustment and fixation are symmetricly set on respectively on side plate 2 and the panel 1.The use of present embodiment is as follows:

(1), location: the patient lies on the back on the CT bed, the panel of placement positioning frame is close to the thoracic wall horizontal positioned, side plate 2 is close to the sidewall of breast, and (face that CT development pipe is housed is close to thoracic wall, the right-angle side of development pipe must all be included focus), utilize horizon rule 7, fixing band 4 to be adjusted to this two boards and be level all around, the right-angle side of CT development pipe parallel with the CT bed (can utilize the CT laser lamp to regulate), beginning CT scan (SCAN).

(2), determine coordinate: (as shown in Figure 4) finds body foci's center aspect on CT development pipe, and on the focus central point point, measure the value of P1P2, P3P4, X, Y.Can find the position of focus central core on the human body surface with two rules of L1L2 and mark point in body surface front and side respectively according to the P1P2=2P3P4 value, front and lateral labelling are coupled together by stretching line and be drawn on the dignity.Line and above-mentioned two lines doing of doing the human body longitudinal axis according to the value of X, Y intersect vertically respectively.Like this, just antetheca and the sidewall at human body found two decussation points, and these two cross points are the three-dimensional anchor point of patient's focus.

Claims

1, a kind of Stereotaxic apparatus is characterized in that: it is made up of panel (1), side plate (2), CT development pipe (3) and fixing band (4), and panel (1) is connected with the mutual vertical fixing of side plate (2), is respectively equipped with scale (5) on every limit of its two boards; On panel (1) and side plate (2), be respectively arranged with CT development pipe (3); Fixing band (4) is separately positioned on panel (1) and the side plate (2).

2, Stereotaxic apparatus according to claim 1 is characterized in that: be respectively equipped with parallel rule (7) on described panel (1) and the side plate (2).
