Description
Technical field
This utility model relates to the directed field of puncture, especially a kind of cranium brain Needle localization scoring tool.
Background technology
Puncture technique is treatment cephalophyma and a kind of effective ways of ventricular hemorrhage, but successful surgery whether key is whether puncture is accurate.
Brain deep cephalophyma can through temples and forehead puncture, and forehead puncture is because drainage tube is through hematoma major axis, and comparatively temples drainage effect is good, and not easy damaged trunk and important brain domain, this needs the auxiliary puncture of stereotactic apparatus usually.
The stereotactic apparatus being usually used in craniocerebral operations at present has import CRW, LEKSELL and domestic MD-2000, ASA series etc., its advantage is that setting accuracy is high, can be used for carrying out brain function operation, but all belong to relatively large instrument and equipment, complex structure, expensive, preoperative preparation time is long, be not suitable for emergency operation, should not promote on a large scale.Although some other stereotactic puncture instrument for cerebral hemorrhage design structurally simplifies greatly, but still more complicated, in operation, after head sterile drape, use comparatively inconvenience.
Because hypertension or traumatic hemorrhage cause the patient of cranium intracerebral hemorrhage, need to carry out cranium brain puncture for treating, concrete operation doctor will position according to the cerebral CT image film of patient or the lower puncture of CT guiding, the accurate location of point of puncture is that puncture is successfully crucial, approach of hypertensive cerebral hemorrhage in basal ganglia hematoma major axis usually and cranium brain major axis have an angle, realize puncturing through hematoma major axis, need to draw corresponding markings at scalp, to determine puncture direction and path, when skull is implemented boring, first capturing position is wanted, angle must be determined when inserting drainage tube, otherwise, operation can not be carried out.The conventionally concrete operations of capable such boring and drainage tube insertion, main still by the experience of doctor, this line consistent with hematoma major axis to be drawn very difficult at head skin surface, still lack standard, standardization at present, operate the inconvenience caused to a certain degree to operator's brain puncturing operation, also bring misery and danger to patient.
Utility model content
For solving the deficiencies in the prior art, this utility model provides that a kind of structure is simple, easy to operate, low price, accurate positioning cranium brain Needle localization scoring tool.
This utility model for achieving the above object, is achieved through the following technical solutions: a kind of cranium brain Needle localization scoring tool, comprises comparison bar and the ruler bar parallel with comparison bar, and one end of crossfoot bar is fixed on comparison bar; Described crossfoot bar has chute, is provided with crossfoot bar slide block in chute, ruler bar is connected with crossfoot bar by crossfoot bar slide block; Described ruler masthead end is provided with half side type angle board, angle board has arc chute, is provided with angle board slide block in chute; Marking-out rule has chute, and its one end is connected with crossfoot bar slide block, and the other end is connected with angle board slide block, and this end end end is arranged on the outer rim of angle board; Described comparison bar, ruler bar, crossfoot bar, angle board and marking-out rule are all provided with scale.
The measuring range of angle board is outwards 0-45 degree by ruler bar.
Crossfoot bar slide block and angle board slide block are all provided with locking device, and locking device center is set to hollow.One is conveniently ruler bar and marking-out rule are fixed, and two is at hollow position, can go out index point with stroke.
First, from CT sheet or CT scan location and patient's concrete condition can determine head point of puncture A, A point is crossed on the cross-sectional line L1 on the maximum hematoma cross section of hematoma at forehead, D is the intersection point of the cross-sectional line L1 on the maximum hematoma cross section of head median sagittal line and hematoma, AD is the distance of point of puncture A to cranium brain median sagittal line, usual 2.5-3.0cmm, hematoma central point B, BA and cranium brain median sagittal line intersect at a C, hematoma central point is apart from brain front distance Y, and hematoma central point is to homonymy temples distance X and puncture angle, angle C.
After knowing above-mentioned data, forehead point of puncture A can be determined, first the slide block on crossfoot bar is moved, be adjusted to the distance of AD and lock slider, adjustment marking-out rule slide block, marking-out rule is moved on the position at angle board C angle, and lock slider, then comparison bar is overlapped with cranium brain median sagittal line, and the line making ruler bar and mistake A be parallel to cranium brain median sagittal line parallel overlaps, and A point is overlapped with forehead point of puncture, now, the position of marking-out rule is exactly the scalp position line that will draw, again marking-out rule is adjacent to scalp (simultaneously, remain comparison bar and cranium brain median sagittal line parallel, ruler bar is parallel with the line that mistake A is parallel to cranium brain median sagittal line parallel), this line is drawn with paintbrush.Then this line was the projection line of the AB line in CT sheet in scalp surface, was the required line cranium brain Needle localization line L of operation.
The beneficial effects of the utility model: structure is simple, and easy to assembly, volume is little, and degree of accuracy is high, can evade the main blood vessel of brain, reach minimum to Cranial nerve injury as birth trauma, and the setting of marking-out rule chute, can make line precisely errorless, is suitable for Clinical practice of performing the operation.
