Abstract

The utility model provides an intracranial focal body surface projection CT and MRI locating mark stick which is characterized in that the utility model is composed of a circular marking ring and a middle standard line whose both ends are connected with the circumference of the marking ring, and non-drying adhesives with dye are painted on one side surface of the marking ring and the middle standard line. The utility model solves the injuries and inconvenience which is brought by traditionally using a screw to fix a metallic frame to patients and greatly lightens the pain of the patients. In addition, the utility model has the advantages of simple structure and easy production.

Description

Intracranial lesion body surface projection CT, MRI telltale mark paste

Technical field

This utility model relates to a kind of localized medical apparatus and instruments of cerebral surgery operation that is used for, and especially a kind of intracranial lesion body surface projection CT, MRI telltale mark paste.

Background technology

The head CT inspection is widely used in China's medical industries; but regular meeting runs into incision of scalp and departs from mutually with intracranial lesion and carry out intracranial lesion when operation puncture puncture target spot off-center in clinical position, causes operation unsuccessful or add heavy patient's damage phenomenon.For addressing this problem, the traditional solid location metal framework of normal use in cerebral surgery operation, its operational approach is to carry out CT scan metal framework is fixed on patient's head firmly with screw after, and pathological changes point just can be determined its locus by frame coordinates.Though this method precision height has certain injury to patient, framework all brings a lot of inconvenience to patient's action and operation, belongs to damaging location, and the framework costliness.

Summary of the invention

This utility model provides a kind of patient's of minimizing wound, intracranial lesion body surface projection CT, MRI telltale mark easy to use to paste for solving the technical problem that exists in the known technology.

The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:

Intracranial lesion body surface projection CT, MRI telltale mark paste, and are made up of the middle graticule that annular Marking ring, two ends are connected on the Marking ring circumference, and it is characterized in that: described Marking ring and middle graticule one side scribble the adhesive sticker of band dyestuff.

This utility model can also adopt following technical measures:

Described Marking ring and middle graticule are Marking ring and the middle graticule that metal material is made.

Described Marking ring and middle graticule are Marking ring and the middle graticule that hollow plastic material is made, and in it is hollow cod-liver oil are housed.

Advantage and the good effect that the utlity model has are: carry out CT scan owing to have the Marking ring of graticule in the middle of patient head is pasted, so can determine that intracranial lesion is mapped to the correspondence position of scalp by the different distance between three gauge points in each layer images, alleviate patient's misery greatly, again because the adhesive of Marking ring contains dyestuff, can on patient's scalp, stay the shape of locator markers so again, even remove Marking ring after the CT scan, the design of otch or point of puncture also can undergo surgery according to the projection that graphical measurement goes out focus, very convenient, this utility model also has simple in structure in addition, the advantage that is easy to make.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the another kind of structural representation of this utility model;

Fig. 4 and Fig. 5 are this utility model user mode figure.

Among the figure: 1 Marking ring, 2 graticules, 3 contain dyestuff adhesive sticker, 4 hollow Marking rings, 5 hollow.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, being used for CT scan telltale mark ring 1 is to be made by the endless metal silk, the tinsel diameter of section is φ 2mm, the Marking ring diameter is that φ 80mm is (according to head size and focus size, Marking ring also can be made into different-diameter: be shaped on two ends in the middle of φ 50mm-φ 100mm) and be connected graticule 2 on the Marking ring circumference, graticule is also made by φ 2mm tinsel.For Marking ring is pasted on patient's scalp, on a side of Marking ring, scribble the adhesive sticker 3 that contains dyestuff, as shown in Figure 2.If that adopts that plastic material makes has Marking ring 4 and a hollow graticule thereof of hollow 5, with cod-liver oil be loaded on hollow in, then can be used for the Marking ring of head nuclear magnetic resonance scanning imaging (MRI), as shown in Figure 3.

Using method:

Patient's clean scalp of having one's hair cut, select the big ting model of probe position, position and Marking ring according to the lesions position of initial Cranial Computed Tomography demonstration, its paste position is can cover the pathological changes size for good, the middle graticule of Marking ring is parallel with the human body longitudinal axis, selects the scanning bed thickness (3-10mm) of CT machine to scan according to the focus size then; On CT image focus plane, can see the cross section shadow and the focus of three Marking rings, its three gauge point spacing differences of each layer images, measure its spacing, be converted into actual numerical value by the scale of having given in the image, the reuse ruler is measured the aspect and the graticule of patient head respective value, measure the longitudinal separation of three gauge points and focus, mark focus at this aspect subpoint in scalp surface, each aspect focus subpoint line can be obtained the projection of focus integral body at scalp, can design out cranium flap otch or point of puncture then, as shown in Figure 4 and Figure 5.

Claims
