Abstract
The present invention relates to a stereo brain orienting instrument for the stereo orientation of the focus in the brain and a use method thereof. The orienting instrument is composed of a semicircle positioning puncture frame (2), a positioning slider (6), a fixed rod (1) and a puncture device (4). The use method comprises the following steps: marking out the anterior dimension point A and the rear dimension point B by combining a focus target point O on a CT/MR film; making a semicircle and a tangent line by using O as the center of circle and R/K as the radius; actually measuring the lengths of A'C', AA', BB', CC' and DD' and multiplying the results with a factor K; using the data to regulate the orienting instrument; after determining a puncture point P and the angular position of the puncture device, fixing the orienting instrument to the skull for puncture. The orienting instrument has the advantages of simple operation, short preparation time, timely emergency treatment and capability of stereo puncture treatment.
Description
The present invention relates to the medical apparatus and instruments of the three-dimensional location of a kind of intracerebral lesion usefulness.
At present domestic and international modern high accuracy CT stereo brain orienting instrument be applied to clinical, but the complex operation of application process, before the art time long, to the critical patient, valuable time has been incured loss through delay in haziness patient's rescue, moreover the costing an arm and a leg of this instrument.
The purpose of this invention is to provide a kind of apparatus simple in structure,, determine lesions position, calculate focus, adjust this apparatus, can carry out puncture for treating, in time give emergency treatment to a patient to the head marginal dimension in conjunction with the CT/MR sheet.
Purpose of the present invention realizes by following measure, position finder is by the semicircle localised puncture frame (2) of 180 degree semi arches and two ends tangent line extension, the middle part of its width is provided with corresponding groove, there is groove the groove inboard, four location sliders (6) are housed in the groove, locate the hold-down bars (1) of packing in the slider, and be fixed in semicircle localised puncture frame by nut (5), perforator (4) is fixed in a certain angular position of semicircle localised puncture frame by nut (5) in groove.
The using method of this position finder is the brain CT/MR sheet according to patient, determines intracerebral lesion target spot O, marks the forward and backward footpath point A of head, B, the CD line of making to be parallel to AB by the O point meets at some C, the D of head, with the O point is the center of circle, and R/K is a radius with the position finder inner arc radius, makes semi arch, hand over CD in C ', D ', cross C ', D ' makes tangent line, hands over the AB line in A ', B ', actual measurement A ' C ', AA ', BB ', CC ', DD ', respectively multiply by K again, K is CT/MR sheet and actual head ratio value coefficient.Then A ' C ' * K determines the spacing of two secured in parallel rods, and AA ' * K, BB ' * K, CC ' * K, DD ' * K determines the distance of stretching in four hold-down bars are on semicircle localised puncture frame, by above-mentioned data, adjusts position finder.Determine point of puncture P, then OP has determined the angular position of perforator (4) in semicircle localised puncture frame groove, on the aspect of patient's scalp, draw camber line and A, B, C, D, P point then, be contacted with behind A, B, C, the D four hold-down bars on the position finder fixing respectively, carry out puncture for treating, puncture needle (3) can be looked the focus situation and change.
Advantage of the present invention is, and is simple in structure, with low cost, marks this position finder according to the CT/MR sheet and is fixed in the head position dimension, can carry out puncture for treating after fixing, therefore, the time that gives emergency treatment to a patient is short, rescues in time, can puncture in head position solid, easy and simple to handle, be easy to apply.
Description of drawings is as follows:
Fig. 1 is that the structure of CT/MR stereo brain orienting instrument is used sketch map.
Fig. 2 is the E-E profile of Fig. 1.
The present invention will be further described in conjunction with the accompanying drawings, the heart is set at the O point among the focus target spot that occurs on the CT/MR sheet according to patient, the anteroposterior diameter of head is set at A, the B point, make the parallel lines friendship head of AB in C by the O point then, the D point, with O is the center of circle, with position finder inner arc radius R/K is radius, make semi arch, hand over CD in C ', D ', cross C ', D ' makes tangent line, hand over AB in A ', B ', actual measurement A ' C ', AA ', BB ', CC ', DD ' multiply by COEFFICIENT K more respectively, adjusts the distance of stretching distance and two secured in parallel rods within four hold-down bars on the position finder, determine the point of puncture P on the head, OP has determined the angular position of perforator (4) in semicircle localised puncture frame groove, finish above-mentioned preparation after, the camber line and the corresponding A of the aspect of promptly on patient's scalp, drawing, B, C, D, the P point, hold-down bars on the position finder is fixed in A, B, C, D 4 points can carry out puncture for treating.If the P point is not in same aspect, then unclamp the hold-down bars of 2 of A, B, with position finder in the CD axis turns to the plane of ordering by P, the hold-down bars that fixing former A, B are 2, carry out puncture for treating again, puncture needle (3) can be replaced by biopsy needle according to the concrete condition of focus, the hematoma destroyer is got thing pincers etc.
