Abstract
The utility model provides a three-dimensional orientation device with a real-time guiding function, which comprises a three-dimensional orientation device part and a sensor part, wherein the three-dimensional orientation device part comprises a chassis, an alpha arched frame, a beta arched frame and a fastener, wherein a guiding hole is formed on the fastener, and the tightness of the fastener can be adjusted; and the sensor part comprises an alpha angle sensor, a beta angle sensor and a range sensor. In the utility model, because the sensors are arranged on the three-dimensional orientation device, operators can be guided in real time, thereby providing convenience for operations and improving the quality of operations.
Description
Technical field
This utility model relates to stereotactic apparatus, particularly a kind of stereotactic apparatus of can the guiding in real time patient when human or animal is carried out craniocerebral operations operating theater instruments accurately being delivered to target spot.
Background technology
Stereotactic apparatus is a kind of can more accurately the location intracranial target under the cooperation of image location technology, then operating theater instruments such as microelectrode, puncture needle are accurately inserted the specific target spot of intracranial, leaving and taking a kind of surgical unit of tissue specimen, damage target spot place's tissue or removal focus, is medical diagnosis on disease, treatment and zooperal common equipment.A kind of known China Patent No. is that " ZL200720054994.0 ", name are called " a kind of stereotactic apparatus simple in structure " described stereotactic apparatus of patent and are based on the linear directional principle at present, determine two azimuths so that determine the puncture direction by two segmental supports that are fixed on the chassis, then, determine apart from operating theater instruments is delivered to target spot according to distance parameter.This kind stereotactic apparatus needs the subsidiary framework that can cover whole operative regions unlike the stereotactic apparatus that adopts the three-dimensional coordinate positioning principle, therefore, its volume just can be done lessly, thereby simple in structure, with low cost, has promoted stereotactic apparatus popularizing in surgical operation.But this stereotactic apparatus can not be in operation process shows the reference for the patient in real time with the position of operating theater instruments, therefore, can't realize in the art guiding in real time accurately.
The utility model content
The purpose of this utility model provides a kind of stereotactic apparatus with real-time guiding function, it can realize in the art the actual operating position of living in of operating theater instruments being shown, thereby can be to the stereotactic apparatus of patient's guiding in real time, so that provide convenience and improve the operation quality for operation.
The stereotactic apparatus with real-time guiding function that this utility model provides comprises stereotactic apparatus and pick off two parts: said stereotactic apparatus partly comprises chassis, α segmental support, β segmental support, with and on securing member that a bullport arranged and the scalable degree of tightness.Sensor section comprises a α angular transducer, a β angular transducer and a range sensor, the α angular transducer is fixedly installed on α segmental support and the chassis, the β angular transducer is fixedly installed on β segmental support and the chassis, with respectively to the α azimuth of operating theater instruments with respect to a certain reference point in the space, the azimuthal variation of β is measured, the part of range sensor is fixedly installed on the securing member, and another part of range sensor is fixedly installed on the operating theater instruments so that the variation of operating theater instruments straight-line displacement is measured when using operating theater instruments.Measure with the variation to α azimuth, β azimuth and the straight-line displacement of operating theater instruments respectively.The variation numerical value of the α azimuth of operating theater instruments, β azimuth and straight-line displacement can be input to the computer assisted surgery planning system and finish demonstration to the actual operating position of living in of operating theater instruments, thereby to patient's guiding in real time.
This utility model is owing to be provided with pick off on stereotactic apparatus, thereby can both for operation provides convenience, can improve the operation quality again to patient's guiding in real time.
Description of drawings
Fig. 1 for this utility model say a kind of structural representation of stereotactic apparatus with real-time guiding function.
Fig. 2 is the another kind of structural representation of above-mentioned stereotactic apparatus.
The specific embodiment
With reference to Fig. 1: the stereotactic apparatus with real-time guiding function that this utility model provides comprises stereotactic apparatus and pick off two parts: said stereotactic apparatus partly comprises chassis 1, α segmental support 2, β segmental support 3, with and on securing member 4 bullport and the scalable degree of tightness is arranged.Sensor section comprises a α angular transducer 5, a β angular transducer 6 and a range sensor 7, α angular transducer 5 is fixedly installed on α segmental support 2 and the chassis 1, β angular transducer 6 is fixedly installed on β segmental support 3 and the chassis 1, with respectively to the α azimuth of operating theater instruments with respect to a certain reference point in the space, the azimuthal variation of β is measured, the part of range sensor 7 is fixedly installed on the securing member 4, and another part of range sensor 7 is fixedly installed on the operating theater instruments 8 so that the variation of operating theater instruments 8 straight-line displacements is measured when using operating theater instruments 8.Equivalence, α angular transducer 5 also can be arranged on α segmental support 2 and the securing member 4, and β angular transducer 6 also can be arranged on β segmental support 2 and the securing member 4.
With reference to Fig. 2: angular surveying device of the present utility model can adopt doube bridge formula structure, and it has advantages of higher stability.The set-up mode of pick off on the stereotactic apparatus of this structure is same as described above.
When this utility model is used: in a conventional manner stereotactic apparatus is fixed on the skull and carries out the image location scanning, the image data input computer aided planning system that obtains is carried out Flame Image Process, determine surgical target.The output signal of all displacement transducers is transferred to the computer aided planning system the actual operating position of living in of operating theater instruments is shown that in real time the patient adjusts the operating theater instruments direction of insertion in real time according to the locus of operating theater instruments that shows in real time on the display and surgical target and insertion depth is sent to operating theater instruments surgical target and finished operation.
Claims (2)
1. stereotactic apparatus with real-time guiding function, it is characterized in that it comprises stereotactic apparatus and pick off two parts: said stereotactic apparatus partly comprises the chassis, the α segmental support, the β segmental support, with and on securing member that a bullport arranged and the scalable degree of tightness, Sensor section comprises a α angular transducer, a β angular transducer and a range sensor, the α angular transducer is fixedly installed on α segmental support and the chassis, the β angular transducer is fixedly installed on β segmental support and the chassis, and the part of range sensor is fixedly installed on the securing member.
