Abstract

The utility model discloses a multifunctional tumor positioning ruler of the radiotherapy positioning used for the tumor patient, comprising a ruler (1) and a fastening screw (2). The ruler (1) is provided with a location mark and groove (3), according to the patient condition, and the ruler (1) forms various shapes through the fastening screw (2); the ruler can be directly positioned on the pathological change body, the ruler is matched with a simulated locator, the operation radiological installation is carried out the radiotherapy, and the deformable positioning is the pathological change body surface which directly positions the body surface; the multifunctional tumor positioning ruler has the features of exact positioning, rapidness, convenience, and utility; the positioning error is decreased, and the damage of the radioactive ray to human body is decreased.

Description

The multifunctional tumor positioning rule

One, affiliated technical field

This utility model relates to a kind of medical supplies, is used for the radiocurable location of tumour patient, a kind of specifically when being mainly used in tumour radiotherapy accurate location and the positive multi-functional positioning rule of effect of radiotherapy instrumental error.

Two, background technology

Malignant tumor is a commonly encountered diseases, and frequently-occurring disease is the disease of serious harm human health, is to cause human dead second largest reason in China.Certain areas and city have become first cause of death.Radiotherapy is one of main means of treatment malignant tumor, before patient does radiotherapy, earlier tumor locus to be located, to determine the scope of irradiation, shine with radiotherapy apparatus such as accelerator or brills then, localized accurately whether, directly have influence on the effect of treatment.Orientation range is big, ray damages normal structure easily, causes physical hazard, also causes radioactive inflammation easily, patient is caused unnecessary harm, the little tumor of scope can not get effective irradiation, can not kill cancer cell, make the tumor continued growth easily, or cause transfer, disease can not get control, and there is following point in the simulated positioner that uses when the location at present:

1, simulated positioner indicated number and actual location number have error;

2, because the influence that the machine imaging is amplified makes locator value and actual result that error be arranged.

3, position changes, and organ movement etc. can cause error.

For above-mentioned reasons, can cause machine error, cause the illuminated position and the position of actual irradiation to be departed from, thereby cause illumination error.

Three, summary of the invention

The purpose of this utility model provides a kind of ruler of multifunctional all, and becoming exsomatizes orientates the body surface location that is placed on diseased region as, has improved accuracy, has reduced error, has reduced the infringement of lonizing radiation to human body.

For achieving the above object the technical scheme that this utility model is taked: form by scale, holding screw etc.Scale is no less than 2, and scale is provided with position mark and groove, and holding screw passes 2 grooves on the matched scale with 2 matched fastening connections of scale.Scale can be a ruler, also can be the arc chi, the strap clamp angle etc. shape, like this under the connection of holding screw, several scales are formed different shapes, as square, rectangle, triangle, trapezoidal, circular, oval and various irregular shape.

When using this utility model, according to patient, select various scales for use, by the required shape of being connected into of holding screw, by the position mark on the scale, determine the shape size, be placed on patient's body surface, be used with simulated positioner, the staff operates shape that radiological installation forms along this utility model and moves and get final product.

Because this utility model can be according to patient's pathological changes situation, random set is synthesized different shape and size, can be placed directly in patient's body surface, accurate positioning has changed isolated operation, has reduced the error of simulated positioner itself, reduced the infringement of illuminated line to human body, but energy savings again.Therefore, the utlity model has the direct body surface location that change is exsomatized and orientated diseased region as, accurate positioning, quick and easy, practical has reduced position error, has reduced the characteristics such as infringement of lonizing radiation to human body.

Four, description of drawings

Accompanying drawing is this utility model sketch map

Five, specific implementation method

Accompanying drawing is an embodiment of the present utility model

This utility model is made up of scale (1), holding screw (2) etc.Scale (1) can be a ruler, also can be with arcual or other form, and present embodiment is a ruler, and scale (1) is provided with groove (3) and position mark.Present embodiment is provided with 4 scales (1), holding screw (2) passes the groove (3) on two scales (1), with fastening the linking up of two scales (1), such 4 scales (1) form square in the connection of 4 holding screws (2), quadrate big I stepped the position mark of holding screw (2) on scale (1) and was provided with, form required form and size according to the patient's tumor situation during use, this utility model of forming is placed on patient's the sick body body surface, the simulated positioner that cooperates radiological installation, the operation radiological installation moves along this utility model and gets final product.Scale (1) can be made up of the material of rustless steel or other anti-irradiation.

Therefore the utlity model has exsomatizes orientates direct body surface location as, accurate positioning, quick, Convenient, practical, reduced position error, reduced the characteristics such as infringement of radioactive ray to human body.

Claims

A kind of multifunctional tumor positioning rule, it is characterized in that including scale (1), holding screw (2), scale (1) is no less than 2, scale (1) is provided with position mark and groove (3), holding screw (2) passes the groove (3) on 2 matched scales (1), with the matched fastening connection of 2 scales (1).
