Abstract

The utility model discloses a simple variable type positioning ruler for the intracranial hematoma puncture, which is mainly applied to intracranial hematoma puncture positioning. A main body consists of a transparent ruler A (1) and a transparent ruler B (2) which are all marked with scales; one end of the transparent ruler A (1) is connected with one end of the transparent ruler B (2) through a rotating shaft (3); and a supporting point (4) is arranged at one end of the transparent ruler A, which is adjacent to the rotating shaft. The simple variable type positioning ruler has a simple structure, is accurate to calibrate, is economical and practical as well as flexible and variable, is convenient to operate, not only can be used for positioning a puncture point of a skull, but also can measure on a CT (computed tomography) film, is easy to place and carry after being folded, simultaneously can be used as a straight scale and is particularly suitable for primary hospitals.

Description

The simple and easy type variable positioning rule of intracranial hematoma puncture art

Affiliated technical field

This utility model relates to medicine technology field, is specifically related to the simple and easy type variable positioning rule of intracranial hematoma puncture art.

Background technology

Wicresoft's intracranial hematoma puncture art is one of effective method of treatment cerebral hemorrhage, and removing hematoma with operation of opening cranium, to compare its superiority be tangible.And the accurate location of intracranial hematoma minimally-invasive treatment never has a relatively method of standard.In recent years, use stereotactic apparatus location levels of precision height, good reproducibility.But stereotactic apparatus mostly is frame-type, and the heavy operation of instrument is wasted time and energy, and wound is bigger, brings certain misery and sense of discomfort to the patient, especially is not suitable for emergency case's location.Also influence the operation of operation and appearing of target spot simultaneously, extensive use has been subjected to very big restriction.Consult nearest pertinent literature report, having application market to sell has the tape of centimeter scale, draws the scale shown in the CT image on the opposite of centimeter scale and carries out scalp target spot location or use single pin or many thin bone section fence positioning rules are determined the point of puncture of scalp.Because of the external form of the thin and thick of human body scalp soft tissue and head different, all very undesirable with tape and single pin positional accuracy and degree of accuracy, and locate as positioning rule with the bone section: once the bone section itself that is the thin 10mm length of making 3mm is not the part nothing the matter, and so thin bone section lacks certain intensity and toughness, do not note slightly and will fracture, lack practicality.

Summary of the invention

Along with the minimally-invasive treatment of intracranial hematoma the applying of the whole nation, it relatively is tangible that the hematoma treatment is removed in its superiority and operation of opening cranium.And one of key of minimally-invasive treatment is the hematoma and puncture needle delivered to the hematoma center of how accurately puncturing, and is convenient to hematoma remove as early as possible, particularly under the little situation of brain deep hematoma or quantity of hematoma, is difficult to accurately hold as no science, accurate method.And that the cranium brain reduces unnecessary wound as extremely special nervous tissue as far as possible is extremely important from saying clinically.In order to overcome the scarce limit of localization method in the past, this utility model has designed and produced the simple and easy type variable positioning rule of intracranial hematoma puncture art according to mathematical principles such as 3 D stereo coordinate and some identity distances.

The technical scheme that its technical problem that solves this utility model adopts is: main body is made by indicating graduated transparent ruler A and transparent ruler B, and an end of two transparent rulers connects by turning cylinder, and the end that transparent ruler A goes up near turning cylinder is provided with fulcrum.

The beneficial effects of the utility model are: simple in structure, demarcate accurately, and economical and practical, flexibility and changeability, easy to operate, launch both to have can be used for the head puncture point orientation, also can on the CT sheet, measure, fold and then be easy to place and carry, can make ruler simultaneously and use, be specially adapted to basic hospital.Can make accurate localization to the scope and the hematoma puncture target spot of intracranial hematoma (comprise under intracerebral hemorrhage, the dura mater, extradural hemorrhage).

Description of drawings

Below in conjunction with accompanying drawing this utility model is further specified:

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

Fig. 2 is that this utility model CT sheet is measured the user mode sketch map;

Fig. 3 is that this utility model cranium table is drafted point of puncture user mode sketch map.

Among the figure: 1. transparent ruler A, 2. transparent ruler B, 3. turning cylinder, 4. fulcrum, 5. scale, 6. point of puncture is 7. drafted at the hematoma center, 8.O-M line, 9. layer distance.

The specific embodiment

This utility model main body is made by transparent ruler A (1) that indicates scale (5) and transparent ruler B (2), and an end of two transparent rulers connects by turning cylinder (3), and the end that transparent ruler A goes up near turning cylinder is provided with fulcrum (4).During use simple and easy positioning rule is launched (as Fig. 2), get maximum aspect hematoma center, hematoma position (6) as the puncture target spot according to the CT sheet, measure the plain CT sheet first aspect O-M line (8) to the theoretical of hematoma center aspect (according to scanning bed thickness and bed thickness at interval) promptly layer distance (9) and hematoma center to the distance of skull occipitalia or forehead, after being converted into actual range in proportion, both at the intersection point of cranium table for drafting point of puncture (7), be hematoma in principle apart from scalp recently, avoid trunk, blood sinus and critical function district and be as the criterion.Measure the nearest vertical dimension of hematoma center to scalp, this is apart from the depth of needle that promptly punctures.Also can under the CT guiding, position.

Claims

1. simple and easy type variable positioning rule of intracranial hematoma puncture art, it is characterized in that: main body is made by transparent ruler A (1) that indicates scale (5) and transparent ruler B (2), one end of two transparent rulers connects by turning cylinder (3), and the end that transparent ruler A goes up near turning cylinder is provided with fulcrum (4).
