Abstract
The utility model relates to a kind of making rulers for radiotherapy, contain the orthogonal cross plate blade of cross bar and vertical bar, it is characterised in that: cross bar both ends are supported in vertical bar by symmetrical brace, and vertical bar and brace intersection are downwardly extending plate ruler handle；It is respectively equipped with one section of hollow slots along the center line of cross bar and vertical bar in cross plate blade confluence, two sections of hollow slots form the positive cross of a hollow out after crossing.
Description
Technical field
The utility model relates to a kind of medical instrument, especially a kind of making ruler for radiotherapy.
Background technique
Clinically, general 70% or so tumour patient needs to do radiotherapy, when in order to ensure patient per's treatment
The consistency and repeatability of position, doctor and therapist can be in patient's skin surfaces and the plastic face mask (body cover) of fixed patient
On do some telltale mark lines, in order to which radiographer is during Case treatment, quickly and accurately put position treatment.Therefore it protects
The accuracy and repeatability for demonstrate,proving radiotherapy group position are one of the important contents of radiotherapy quality control.Radiotherapy is taught book
Describe in this way: if radiographer puts position accuracy errors 3mm over the course for the treatment of, curative effect can decline 3.3%, error 5mm,
Curative effect can decline 18.4%, and error 6mm, curative effect can decline 33.1%.It can be seen that radiographer is in entire radiotherapy
It plays a key role, the precision that therapist puts position is higher, and the curative effect of patient is also better.So industry provides radiotherapy
The error of the pendulum position treatment of teacher allows within 2mm.Mark line is the special marker that radiographer puts position, extremely important, mark
The accuracy of note line influences whether that radiographer puts the accuracy of position, it is radiotherapy radiotherapy special token pen in disease
Be marked on the body surface (or body mould) of people, radiotherapy special token pen is easy to use, will not to medical staff, patient, therapeutic room,
Ambient enviroment pollutes, but equally smoothly can arbitrarily mark since the special shape of human body is unable to sensitive paper.Do not marking
Remember the auxiliary of ruler, it is easy to so that the mark line drawn is deviateed or is bent, to generate certain error, such error can
It can lead to patient's therapeutic community's deviation during entire radiotherapy, will affect and control target dose size and its corresponding agent distribution, make
Tumor target cannot get enough dosage, cause target area normal surrounding tissue and important organ by unnecessary irradiation instead.
Traditional labeling method is existed by the three-dimensional localization laser line projection cross hairs of radiotherapy simulative generator (CT localization machine)
In the patient's body surface (or body mould), radiographer according to the cross hairs of laser line projection, uses on the body surface (or body mould) of patient
Marking pen carries out retouching line.Marker pen nib and the hand to hold a pen are easy to block laser cross-line in retouching line process, make to be incident upon
The discontinuous situation of laser rays generation on the body surface (or body mould) of patient, therapist's description laser projection the patient's body surface (or body
Mould) on cross hairs when, it may occur that deviation, to influence positioning accuracy.
Utility model content
The purpose of this utility model is that: overcome above-mentioned prior art defect, provides a kind of suitable for patient's any part
The making ruler of mark line is drawn, accurate, convenient and fast label is carried out convenient for therapentic part of the radiographer to patient, improves setting-out
Precision saves the setting-out time.
Purpose of the utility model is realized as follows: a kind of making ruler for radiotherapy, contains cross bar and vertical bar
Orthogonal cross plate blade, it is characterised in that: cross bar both ends are supported in vertical bar by symmetrical brace, and vertical bar crosses with brace
Place is downwardly extending plate ruler handle；One section is respectively equipped with along the center line of cross bar and vertical bar in cross plate blade confluence
Hollow slots, two sections of hollow slots form the positive cross of a hollow out after crossing.
In the present invention: the hollow slots both ends on cross bar and vertical bar, which are equipped with along center line, extends shallow ridges, wherein horizontal
The extension shallow ridges terminal at both ends is located at the both ends of cross bar on bar, and the terminal that one end extends shallow ridges on vertical bar is located at the top of vertical bar
End, the other end extend the terminal of shallow ridges in vertical bar and the vertical bar of brace intersection.
In the present invention: the groove width of the hollow slots and the nib of marker pen match, extension shallow ridges ditch top
Width be less than hollow slots groove width.
In the present invention: the material of the making ruler is duroplasts or metal.
Utility model has the advantages that due to the positive cross containing hollow out in the plate blade of the utility model, fixed
During position, as long as four ends of the positive cross of the hollow out of plate blade, which are extended shallow ridges, is directed at laser positioning cross hairs, pass through nib
It accurately crosses positioning with the matched marker pen of groove width of hollow slots；Due to making ruler material be duroplasts or metal, especially
Hollow slots both ends on cross bar and vertical bar, which are equipped with along center line, extends shallow ridges, it is ensured that plate blade has certain flexibility and can
The characteristics of being bent with patient body surface (or mold) is suitable for each position radiotherapy label of whole body；The utility model and operation letter
It is single, it is scientific and reasonable for structure, there is very strong practicability.
Detailed description of the invention
Fig. 1 be the utility model relates to a kind of example structure schematic diagram for the making ruler for radiotherapy；
In figure: 1, plate ruler handle, 2, plate blade, 3, the positive cross of hollow out, 4, extend shallow ridges, 5, brace.
Specific embodiment
Attached drawing disclose without limitation the utility model relates to a kind of embodiment specific structure, with reference to the accompanying drawing
This embodiment of the utility model is further described.
As seen from Figure 1, the utility model contains cross bar and the orthogonal cross plate blade 2 of vertical bar, it is characterised in that: horizontal
Bar both ends are supported in vertical bar by symmetrical brace 5, and vertical bar and 5 intersection of brace are downwardly extending plate ruler handle 1；In cross
2 confluence of plate blade is respectively equipped with one section of hollow slots along the center line of cross bar and vertical bar, and two sections of hollow slots form one after crossing
The positive cross 3 of a hollow out.
In the present embodiment, the hollow slots both ends on cross bar and vertical bar, which are equipped with along center line, extends shallow ridges 4, wherein horizontal
Extension 4 terminal of shallow ridges at both ends is located at the both ends of cross bar on bar, and the terminal that one end extends shallow ridges 4 on vertical bar is located at vertical bar
Top, the other end extend the terminal of shallow ridges 4 in vertical bar and the vertical bar of 5 intersection of brace.
When it is implemented, the groove width of the hollow slots and the nib of marker pen match, the width for extending 4 ditch top of shallow ridges
Degree is less than the groove width of hollow slots.
When it is implemented, the material of the making ruler is duroplasts or metal.
When specific implementation: the plate ruler handle 1 of making ruler being held with palm, thumb and index finger pin the two of crossfoot respectively
Four ends of the positive cross of hollow out are extended shallow ridges and are directed at laser positioning cross hairs, firmly pushed, when blade is bent to and patient's body by side
When body surface face (or mold) fits, scored marks in 3 channel of positive cross of hollow out using marking pen, if special cannot
The position directly to make marks is marked using two right-angle sides of the small right angled triangle in plate blade 2.
