Abstract
The utility model relates to a medical utensil which can treat a disease of a brain. One end of a sliding rod is fixed with one end of a horizontal ruler, and the other end of the horizontal ruler is fixed with a vertical ruler. Ruler bodies of the horizontal ruler and the vertical ruler are respectively in sleeve joint with verniers. The bottom side of a body seat is provided with a fixing needle. The body seat is in sleeve joint with the sliding rod through a sliding hole in the body seat. The utility model enhances the accuracy and the success ratio of the puncture to focus in deep part of the brain. The error of the puncture is little; the auxiliary damage of the puncture is reduced. The structure is simple; the operation is convenient and rapid; the utility model is easy to produce.
Description
This utility model relates to a kind of medical apparatus for the treatment of disease of brain.
At present brain deep focus is punctured, as to punctures such as thalamic hemorrhage, internal capsule hemorrhage, brain abscess, intracranial mass lesion focuses, location such as suction and biopsy, domestic still do not have this appliances, some medical institutions' purchasing price costliness, complex structure, the location instrument that operation easier is big, as: stereotactic apparatus and B ultrasonic ultrasonic puncture instrument etc.But there is the hospital of this equipment in China also for counting seldom at present.
The purpose of this utility model is to provide a kind of accurate positioning, and is simple in structure, the simple and easy intracranial puncture guide instrument of being convenient to operate.
The purpose of this utility model is achieved in that main body base socket-connects by sliding eye in it and sliding bar, be fixed with three mutual equidistant and isometric locking pins in the bottom side of main body base, wherein the sliding eye centrage in the pin end line of two locking pins and the main body base parallels, on the main body base of these two locking pin middles, adorn a main body base positioning needle, fixed screw is housed on main body base, one end of rounded sliding bar and an end of horizontal ruler fix, vertical the fixing of one end of the other end of horizontal ruler and Vertical surveyors' staff, on the blade of horizontal ruler and Vertical surveyors' staff, be socketed with positioned cursor respectively and be provided with graduation mark, on each positioned cursor, fixed screw is housed.
Owing to adopt such scheme, improved brain deep focus puncture localized accuracy and success rate, the puncture error is little, reduces patient's misery, it is simple in structure, easy to operate rapidly, manufacture easily.
Below in conjunction with drawings and Examples this utility model is described further.
Fig. 1 is a structure chart of the present utility model.
1. main body bases, 2. locking pins, 3. sliding bars, 4. fixed screws, 5. horizontal rulers, 6. positioned cursor, 7. fixed screws, 8. Vertical surveyors' staffs, 9. main body base positioning needles among the figure
In the embodiment shown in fig. 1, main body base 1 socket-connects by sliding eye in it and sliding bar 3, and slidably, be fixed with three mutual equidistant and isometric locking pins 2 in the bottom side of main body base 1, the pin end of three locking pins constitutes equilateral triangle, wherein there are the pin end line of two locking pins and the sliding eye centrage in the main body base 1 to parallel, one positioning needle is arranged on the main body base of these two locking pin middles, upside at main body base 1 is equipped with fixed screw, one end of rounded sliding bar 3 and an end of horizontal ruler 5 fix, vertical the fixing of one end of the other end of horizontal ruler 5 and Vertical surveyors' staff 8, on the blade of horizontal ruler 5 and Vertical surveyors' staff 8, be socketed with positioned cursor 6 respectively and be provided with graduation mark, on each positioned cursor 6, fixed screw 7 is housed.Also two locking pins can be set in the bottom side of main body base 1 in addition.
This utility model is manufactured according to the three-dimensional coordinate principle, and three mutually perpendicular planes promptly are set in cranial cavity, and fore-and-aft direction is a sagittal plane, and left and right directions is a coronalplane, and horizontal direction is a horizontal plane.Its particular location is all determined by these three planes in cranium harmony in the exterior intracranial any point.Cranium table point of puncture is the projection of intracranial impact point on the cranium surface, and therefore, cranium table point of puncture and intracranial impact point are on same coronalplane and horizontal plane, and promptly on the straight line that coronalplane and horizontal plane intersect, this straight line and sagittal plane are perpendicular.Hence one can see that, and the straight line puncture that coronalplane from cranium table point of puncture along this point and horizontal plane intersect reaches the predetermined degree of depth, can sting mesocrany internal object point.In other words, reach the predetermined degree of depth of intracranial, the impact point of intracranial in can stinging from the perpendicular direction puncture of cranium table point of puncture and sagittal plane.The coronalplane at cranium table point of puncture place is represented on the horizontal ruler 5 of simple and easy intracranial puncture guide instrument and the blade plane of Vertical surveyors' staff 8, the positioned cursor top edge of Vertical surveyors' staff 8 is represented horizontal plane, the angle that is formed by Vertical surveyors' staff 8 and its positioned cursor top edge is the puncture direction, reach the intracranial desired depth along angle direction inserting needle, just may hit point (lesions position).
