Abstract
The utility model relates to a medical appliance-a CT brain stereotaxic direction meter for intracerebral focus puncture. The CT brain stereotaxic direction meter is composed of a semicircular positioning puncture frame (2), a positioning slide device (6), a fixing bar (1) and a puncture device (4). According to a target point O of a focus on a CT brain horizontal scanning film of a patient, the distance of the target point to the front and the rear surfaces of skull is correspondingly marked out to adjust and position the slide device and the fixing bar; after a puncture point P is determined, the semicircular positioning puncture frame is rotated to a plane formed with the puncture point to fix after the centre of circle of the semicircular positioning puncture frame is coincident with the target point O; then the puncture treatment can be carried out. The utility model has the advantages of simplicity, low cost, short preoperative preparation time, and stereotaxic puncture, and is suitable for diagnosing and treating intracerebral space-occupying pathological changes.
Description
This utility model relates to the medical apparatus and instruments of intracerebral lesion puncture usefulness.
Domestic and international modern high accuracy CT stereo brain orienting instrument has been applied to clinical at present, but the complex operation of application process, time is long before the art, patient need wear the headstock and set up reference frame, carry out head CT scanning again, rescue to critical patient, haziness patient and cervical region tubbiness patient causes difficulty, moreover this instrument costs an arm and a leg.Stereotaxis intracerebral lesion perforator can only be applicable to the puncture of CT plate plane, has certain limitation.
The purpose of this utility model provides a kind of apparatus simple in structure, marks the intracerebral lesion position from the CT sheet, calculates the size of intracerebral lesion apart from the head edge, and focus point is overlapped with the center of circle of this apparatus, thereby realizes the arbitrary plane puncture for treating.Instrument cost reduces greatly.
The purpose of this utility model realizes by following measure, it 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, in the slider of location hold-down bars (1) is housed, and is fixed in semicircle localised puncture frame by nut (5).Perforator (4) in groove by a certain angular position of fixed by nut in semicircle localised puncture frame.
The version of semicircle localised puncture frame (2) and location slider (6), can not establish groove at the middle part of its width, and change its width both sides and inboard, slider below, location into version that dovetail groove matches, perhaps change its width both sides into right-angle side, then the version that trench bottom is established rib in the slider below, location of correspondence.Also can establish groove, then locate slider and change into directly and establish one section screw thread, and be fixed in semicircle localised puncture frame by nut by the hold-down bars cylindrical at the middle part of the thickness direction of semicircle localised puncture frame.
The puncture needle (3) at perforator (4) center can be according to the concrete condition of focus hematoma, uses puncture needle instead hematoma destroyer that tip and plug by head 2-4 root filament connect together.
The material of semicircle localised puncture frame (2) is a hard material, as plastics, lucite, corrosion resistant plate, chromium plating steel plate, aluminium sheet etc.
The utility model has the advantages that simple in structurely, cost is low, and is easy and simple to handle, little to patient trauma, before the art time short, can puncture at arbitrary plane, be suitable for diagnosis of occupying lesions in the brain and treatment.
Description of drawings is as follows:
Fig. 1 is the structure of CT stereo brain orienting instrument and uses sketch map.
Fig. 2 is the E-E profile of Fig. 1.
This utility model will be further described in conjunction with the accompanying drawings, go up the focus target spot O that occurs according to unenhanced of patient's head CT, the corresponding A that marks, B, C, the D point, AB is the anteroposterior diameter of head, CD is for by the O point and be parallel to the straight line of AB, calculate OC, the radial dimension of OB, and the parallel distance of CD to AB, the distance that location slider on the adjustment semicircle localised puncture frame and hold-down bars stretch to the center of circle, after making semicircle localised puncture frame be fixed in head, the center of circle overlaps with target spot O, determines scalp point of puncture P, adjust the angular position of perforator, unclamp A, the hold-down bars that B is 2 when making semicircle localised puncture frame intersect the plane around the rotation of CD axle and with point of puncture P, stops operating, fixing A again, 2 hold-down bars of locating of B can carry out puncture for treating.
