Abstract
The utility model provides a stereotaxic instrument capable of real-time guiding, which consists of a stereotaxic instrument part and a sensor part. The stereotaxic instrument part comprises a base plate, an arched support and a fastener with a guiding hole, the fastener can adjust tightness, and the sensor part consists of an Alpha angle sensor, a Beta angle sensor and a distance sensor. Since the stereotaxic instrument is provided with the sensors, an operator can be real-timely guided, and consequently, not only is operation facilitated, but also the quality of operation can be increased.
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 can realize in the art the actual operating position of living in of operating theater instruments is 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 of the energy guiding in real time that this utility model provides comprises stereotactic apparatus and pick off two parts: said stereotactic apparatus partly comprises chassis, a segmental support and securing member bullport and the scalable degree of tightness is arranged on it, one side hinge on segmental support one end and chassis connects or is slidingly connected, and the securing member of scalable degree of tightness is sleeved on the segmental support.Sensor section comprises a α angular transducer, a β angular transducer and a range sensor, the α angular transducer is fixedly installed on segmental support and the chassis, the β angular transducer is fixedly installed on segmental support and the securing member, respectively operating theater instruments is measured with respect to the azimuthal variation of α azimuth, β of a certain reference point in the space, 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.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, Fig. 2 for this utility model say can guiding in real time a kind of structural representation of stereotactic apparatus.
Fig. 3, Fig. 4 for this utility model say can guiding in real time the another kind of structural representation of stereotactic apparatus.
The specific embodiment
With reference to Fig. 1, Fig. 2: this utility model provide can to operating theater instruments in real time accurately the stereotactic apparatus of guiding comprise stereotactic apparatus and pick off two parts: said stereotactic apparatus partly comprises chassis 1, a segmental support 2 and securing member 3 bullport and the scalable degree of tightness is arranged on it, connector 4-1 or the 4-2 hinge of the one side on segmental support 2 one ends and chassis 1 by a tight device with lock connects or is slidingly connected, and the securing member 3 of scalable degree of tightness is sleeved on the segmental support 2.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 segmental support 2 and the chassis 1, β angular transducer 6 is fixedly installed on segmental support 2 and the securing member 3, with respectively to the α azimuth of operating theater instruments 8 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 3, and another part of range sensor 7 is fixedly installed on the operating theater instruments 8 so that the variation of operating theater instruments straight-line displacement is measured when using operating theater instruments 8.
With reference to Fig. 3, Fig. 4: segmental support 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. the stereotactic apparatus of an energy guiding in real time, it is characterized in that, it comprises stereotactic apparatus and pick off two parts: said stereotactic apparatus partly comprises the chassis, on segmental support and its securing member bullport and the scalable degree of tightness is arranged, one side hinge on segmental support one end and chassis connects or is slidingly connected, the securing member of scalable degree of tightness is sleeved on the segmental support, Sensor section comprises a α angular transducer, a β angular transducer and a range sensor, the α angular transducer is fixedly installed on segmental support and the chassis, the β angular transducer is fixedly installed on segmental support and the securing member, and the part of range sensor is fixedly installed on the securing member.
