Abstract
The utility model relates to a positioning instrument for intracranial hematoma puncture. The utility model is composed of a mould frame and a positioning frame. The mould frame is composed of a large circular ring, a middle rod, a horizontal block, an upright rod, a positioning needle, a semicircular ring, a semicircular-ring slide block, a regulation rod and a direction pointer. The positioning frame comprises one large ring which has the same size as the large circular ring of the mould frame and can be sheathed on a human head. The large ring is hinged with a half ring which is identical with the half circular ring of the mould frame. The half ring is provided with a guide rod, a telescopic rod and a semicircular slide block which are identical with the homologous elements in the semicircular ring of the mould frame. When the utility model is used, the utility model finds puncture positions in the mould frame according to a CT or MRT photo, restores the figure of the mould frame on the positioning frame, and can find the head puncture points of patients.
Description
This utility model relates to medical apparatus and instruments, specifically a kind of intracranial hematoma puncture position finder.
The a lot of craniocerebral operations of department of neurology need be by the higher modern stereotactic apparatus of positioning accuracy in the hospital at present, this position finder has import and homemade two big classes, its main feature is location under CT or MRI guiding, though its degree of accuracy is higher, but structure is comparatively complicated, cost is too high, use not very convenient, especially to the hypertensive cerebral hemorrhage patient, need be when bedside carries out the hematoma aspiration art, use this position finder just very difficult, so doctors often seek the thorn point according to the original method that CT or MRI sheet are drawn many lines at patient's head, pretty troublesome.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose wield intracranial hematoma puncture position finder a kind of simple in structure, with low cost, easy to use.
At the foregoing invention purpose, this utility model adopts following technical scheme.A kind of intracranial hematoma puncture position finder, its special character is that it is made up of mould bases and locating rack, described mould bases comprises a large circle, in this large circle, king-rod is housed, being equipped with on king-rod can be along the horizontal block of king-rod slip and rotation, on horizontal block, be equipped with one with king-rod vertical and rotatable flexible vertical rod, telescopic positioning needle is housed on vertical rod, on above-mentioned large circle, also be hinged with semicircular ring, the semicircular ring slide block set is on semicircular ring, the adjusting rod of a scalable rotation is housed on the semicircular ring slide block, the head of this adjusting rod is hinged with the sensing pin, described locating rack comprises a macro ring on the be enclosed within number of people identical with mould bases large circle size, on macro ring, be hinged with a semi-ring identical with semicircular ring in the mould bases, on semi-ring, be equipped with the mould bases semicircular ring in the identical guide bar of corresponding component, expansion link and semicircle slide block
In such scheme, be equipped with the scale of the mutual displacement of reflection between the mutual movable part of all on described mould bases and the locating rack.
This utility model is simple in structure, and is with low cost, easy to use.It is different with the stereotactic apparatus in the background technology, do not need when being CT or MRI to be attached on patient's head, only can on mould bases, find the intracranial hematoma puncture position according to CT or MRI sheet, then locating rack is fixed on patient's head, and on locating rack, restore the appearance of mould bases, just can find the hematoma puncture point at patient's head.This position finder does not have any damage to patient and operator, and it is easy to learn, and is easy and simple to handle, and is clinical very practical.
Below in conjunction with the accompanying drawing illustrated embodiment, describe this utility model in detail.
Fig. 1 is the mould bases structural representation.
Fig. 2 is the locating rack structural representation.
This utility model is made up of mould bases and locating rack.The primary structure of its mould bases is seen Fig. 1.It comprises a large circle 1, and the king-rod 3 by the center of circle is housed in this large circle 1, and the ring wall of the two ends of king-rod 3 and large circle 1 is fixed.Be with a horizontal block 7 on king-rod 3, this horizontal block 7 can be slided and rotation along king-rod 3, axially circumferentially indicates scale along king-rod 3.On horizontal block 7, be inserted with one with king-rod 3 vertical vertical rods 4, indicate scale along the axial and circumferential of vertical rod 4, this vertical rod 4 can stretch in horizontal block 7 and rotate.In vertical rod 4, be equipped with one with vertical rod 4 vertical and telescopic positioning needles 5, axially indicate scale along this positioning needle 5.Also be hinged with a semicircular ring 2 in the outside of above-mentioned large circle 1 ring wall, on the outer wall of its pin joint place large circle 1 rotation scale be housed, be used to write down the angle of semicircular ring 2 and large circle 1 deflection.Be with a semicircular ring slide block 8 on semicircular ring 2, semicircular ring slide block 8 can slide and rotation along semicircular ring 2, indicates scale along semicircular ring 2 axial and circumferential.The adjusting rod 6 of a scalable rotation is housed on semicircular ring slide block 8, axial and circumferential along adjusting rod 6 indicate scale, the head of this adjusting rod 6 is hinged with sensing pin 9, and adjusting rod 6 or sensing pin 9 at the pin joint place are marked with the rotation scale, are used to write down the deflection angle between them.At large circle 1 inner bottom part seat leg 10 is housed.
The primary structure of locating rack is seen Fig. 2.It comprises that one identical with mould bases large circle 1 size is overlapped overhead macro ring 13, and positioning screw 11 is housed on the ring wall of macro ring 13, is used for macro ring 13 is fixed on head.Be hinged with a semi-ring 14 identical with semicircular ring 2 in the mould bases on macro ring 13, same rotation scale also is equipped with at its pin joint place.Semi-ring slide block 16, expansion link 15 and guiding mutually 12 is housed on semi-ring 14, they with mould bases semicircular ring 2 in corresponding semicircular ring slide block 8, adjusting rod 6 and sensing pin 9 identical.
When this utility model uses, find the Cranial Computed Tomography baseline in conjunction with patient's Cranial Computed Tomography sheet, with the large circle in the mould bases 1, king-rod 3 and horizontal block 7 adjust to the same plane of above-mentioned baseline on, the central point of horizontal block 7 is overlapped with the baseline mid point, utilize vertical rod 4 and positioning needle 5 (adjustment angle and distance) can in mould bases, find patient's intracranial hematoma central point, rotate semicircular ring 2 this moment, regulate semicircular ring slide block 8, adjusting rod 6 simultaneously and point to pin 9, the needle point of sensing pin 9 and the needle point of positioning needle 5 are joined, and its intersection is the puncture entry point.If this is important structure (as a pterion), can re-adjustment, reorientate and point to pin 9.After the location, note the scale of each joint, mutual alignment relation (scale) according to semicircular ring 2, adjusting rod 6, semicircular ring slide block 8 and sensing pin 9 in CT sheet parameter and the mould bases, can utilize positioning screw 11 stationary positioned framves at patient's head, and each parts relevant position concerns that corresponding component position relation (scale) is in full accord in (scale) and the mould bases in the adjustment locating rack, and this moment, guide bar 12 ends were exactly hematoma puncture position, patient's head surface.
This position finder does not have any damage to patient and operator, and is easy and simple to handle, is highly suitable for clinical.
