Description
Technical field
This utility model relates to a kind of apparatus that is used for the craniocerebral operations orientation.
Background technology
At present, owing to used advanced Medical Instruments such as CT and MRI, make cerebral thrombosis, intracranial abscess, the clinical diagnosis accuracy rate and the success rate of operation of cranium disease of brain such as brain tumor improve greatly.Carrying out neurocranial surgery when operation, generally is earlier with survey tools such as rules, measures the position of focus from the CT film, then in labelling location, corresponding cranium brain body surface place, as paracentetic point of entrance or open the otch of cranium art.This localization method trivial operations has increased difficulty to operation, and owing to the Coordinate Conversion that needs repeatedly, can produce bigger error, and positional accuracy is not high, causes unnecessary damages to the patient easily.Now, having some is the location instrument of neurocranial surgery operation designing specially, its degree of accuracy and practicality all improve, a kind of cranium brain puncture positioning rule as the design of the utility model patent of the patent No. 94204573, constitute by angle square and vernier, angle square two arms are equipped with scale, vernier place angle square long-armed on, vernier is provided with a slide rule of vertical relatively slip with it, and the slide rule lower end is provided with the positioning rule that can slide relatively with it of a level, and the positioning rule face is provided with positioning through hole, puncture the operation before, only use one can on patient's cranium brain, determine patient part to this chi, still, the big problem of the still unresolved position error of this positioning rule.The patent No. is that 91101365 patent of invention has designed a kind of brain stereotactic system that is installed in CT scan head of a bed portion for another example, the coordinate of this system and CT scan system coordinates overlaid, wherein focus target spot and biopsy pinpoint are placed in same CT scan aspect, target spot just in time is on 0 value of V axial coordinate in vertical direction, the biopsy needle carriage is arranged to sphere centre positioning device, make biopsy needle along coronalplane and sagittal full range of movement reach respectively ± 60 ° and 180 °, though this system has high orientation precision, but its complex structure, practicality are not high.
Summary of the invention
This utility model improves at the weak point of above-mentioned various apparatuses, designed a kind ofly to have higher orientation accuracy, and cranium brain simplified oriententation instrument simple in structure, swift to operate again.
For this reason, the cranium brain simplified oriententation instrument of this utility model design comprises the locating rack of being made up of horizontal arm and two upright arms, and an end of upright arm is connected with an end vertical fixing of horizontal arm, the other end is provided with dog screw; The front of horizontal arm and upright arm is provided with scale, side offers groove; Directed slide block set is located on horizontal arm and the upright arm, and can slide along groove, and directed slide block is fixed by holding screw, the directional catheter of hollow by threaded engagement, be arranged in directed slide block center; Dog screw and directional catheter are interchangeable.
Utilize horizontal arm, upright arm and the directed slide block of this position finder, the intracranial lesion position that the CT film can be provided, be marked on exactly on the body surface of patient's cranium brain, then, intracranial deep pathological changes carried out stereotactic puncture and various operation technique accurately by directional catheter.According to clinical needs, also directional catheter can be changed to the dog screw place, directly carry out stereotactic puncture, have easy, practical characteristics.
Description of drawings
Fig. 1, be the front view of this utility model cranium brain simplified oriententation instrument.
Fig. 2, be the right view of Fig. 1.
Fig. 3, be the vertical view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, cranium brain simplified oriententation instrument comprises horizontal arm 1 and two locating racks that upright arm 2,3 is formed that connected by mutual vertical fixing, and an end of two upright arms is equipped with dog screw 4,5.The front of horizontal arm 1 and two upright arms 2,3 is provided with graduated scale 6, side offers groove 7,14.Directed slide block 8,9 is sheathed on horizontal arm and the upright arm, and can slide along groove 7,14, and holding screw 10,11 is used for directed slide block 8,9 locking positionings. Directional catheter 12,13 is arranged in the center of directed slide block 8,9 by threaded engagement, and dog screw is identical with external diameter, the pitch of directional catheter, but mutual alternative in the use.
The using method of this position finder is as follows; On the CT aspect at place, intracranial lesion center, measure the vertical dimension (X coordinate figure) of pathological changes centre-to-centre spacing centrage and the vertical dimension (Y coordinate figure) on brainpan top, measure the vertical dimension (Z coordinate figure) of this CT aspect and OM line (paropia and external auditory meatus hole line).Then, mark sagittal centrage and OM line at the brainpan body surface, mark the pathological changes center baseline (corresponding to pathological changes center aspect) that is parallel to the OM line according to the Z coordinate figure, sagittal centrage and pathological changes center baseline and sagittal centrage all intersect, according to X, Y coordinate figure brainpan body surface marks the respective point at pathological changes center.Position finder is placed in patient's brain, dog screw 4,5 is fixed on the intersection point of pathological changes center baseline and sagittal centrage, according to X, the Y coordinate figure, move of correspondence position and the locking of directed slide block 8,9 to graduated scale 6, turn directional catheter 12,13, the top that makes it to protract are located on the brainpan body surface then, can introduce directed pin by the centre bore of directional catheter 12,13, cranium brain deep pathological changes is punctured, the degree of depth of puncture is: sagittal paracentesis depth is the Y coordinate figure, and edgewise paracentesis depth is the 9CM-X coordinate figure.According to clinical needs, also directional catheter 12,13 can be changed to dog screw 4,5 places, directly carry out stereotactic puncture.
