Description
Technical Field
The utility model relates to the field of medical devices, in particular to the field of positioning of craniocerebral lesions.
Background
The positioning of the brain focus is a key factor for the success of the craniocerebral operation. The traditional simple positioning method without positioning marks needs to rely on CT to scan according to standard lines, but in actual work, particularly for critical patients, scanning is not standard due to unsmooth breathing/body position forcing and the like, the traditional approximate positioning error is large, and the puncture failure rate is increased. The existing technology needs hundreds of thousands or even millions of stereotactic devices, the installation process is complicated, even the skull nail needs to be fixed, the time consumption is long, the existing technology is particularly not suitable for the patient needing emergency rescue, and the existing complex positioning marking device needs to rely on at least two times of CT scanning, and needs to move the patient again, the time consumption is long, so that some critical patients cannot complete, or the risk of the patient is increased and the treatment time is delayed because of the positioning process. At present, a relatively simple positioning device needs to scan at least two to three times, and the scanning is performed again to find the optimal plane after the positioning is carried out on the optimal plane, particularly, the scanning plane changes due to the fact that the positioning device cannot be matched with a patient, and positioning errors are generated, so that the positioning is inaccurate.

Detailed Description
In order to clearly show the objects, technical solutions and advantages of the present invention, the following detailed description of the embodiments of the present invention will be further described with reference to the accompanying drawings.
Example 1
The craniocerebral focus positioning device shown in the figure 1 comprises a first positioning film 1, a second positioning film 2, and a plurality of metal strips 3 which are regularly distributed are arranged on the first positioning film 1 and the second positioning film 2, and is characterized in that the metal strips are arranged in parallel, the width of each metal strip 3 is 2mm, the length of each metal strip is 0.2-10cm, the thickness of each metal strip is 0.01-0.1mm, the metal strips 3 are arranged in a length increasing mode or a length decreasing mode, and two adjacent metal strips on one positioning film are spaced at the same distance.
Preferably, the positioning film is made of transparent, flexible and non-stretchable material and can adapt to the shape of the skull.
Preferably, the metal strip 3 is made of copper.
Preferably, the following steps: the interval between two adjacent metal strips on the first positioning film 1 and the second positioning film 2 is 2mm, and the length difference of the adjacent metal strips is arranged in an increasing or decreasing mode by 0.2 cm.
Preferably, the following steps: the interval between two adjacent metal strips on the first positioning film 1 and the second positioning film 2 is 5mm, and the length difference of the adjacent metal strips is arranged in an increasing or decreasing mode by 0.5 cm.
