Abstract
The invention discloses a kind of stereotaxis guide, including positioning cap and guiding cone, the positioning cap is provided with center hole, guiding cone top is cylindrical structural, bottom is inverted round stage structure, inside has the through hole that aperture tapers into from top to bottom, and the through hole lower end diameter is identical with center hole；The guiding centrum upper end edge has fillet, and positioning cap has the filleted corner being coupled with being oriented to centrum upper end edge.The present invention not only can determine puncture path by orienting the circular hole of cap center hole and guiding cone lower end, and guiding ventriculoscope is advanced into the target area of operation along default path；And the adjustable space of the taper of axle centered on puncture path is provided for ventriculoscope, the circular hole that cone lower end is directed to before puncture is placed on brain tissue surface, so as to which ventriculoscope is disturbed with the brain tissue minimized, obtains maximized range of observation.
Description
Technical field
The invention belongs to medical instruments field, is related to a kind of stereotaxis guide, the stereotaxis for ventriculoscope.
Background technology
At present, conventional stereo brain orienting instrument has Leksell orientation systems, BRW/CRW orientation systems, Todd-well fixed
To system；There are the ASA-601 of Shenzhen Anke High Tech. Co., Ltd, 602 direction finders etc. in the country, all of above stereotactic apparatus
Principle is all to need to install a framework first outside head, then this framework and patient are carried out to CT or MRI scanning together,
Then the image of patient's cerebral CT or MRI with frame coordinates parameter tags, each image anatomy in patient's cranium brain are obtained
Structure can all have a corresponding coordinate value, the mechanical data then defined by stereo brain orienting instrument in this coordinate-system
The coordinate points, and the puncture path determined by guider and stopper are positioned, apparatus is guided to the coordinate points, so as to real
Existing brain stereotactic.
But the problem of above-mentioned direction finder, is that guider, to the fixation of guide pin, is only used for specific bit with stopper
The guiding with path is put, and surrounding environment can not be expanded to.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of stereotaxis guide, the guide is fitted
For stereo brain orienting instrument and uncontrolled junction, that is, it is adapted to the positioning of target spot, can also realizes within the specific limits to target spot
The processing of surrounding.
The purpose of the present invention is achieved through the following technical solutions：A kind of stereotaxis guide, including positioning cap and
Guiding cone, the positioning cap are provided with center hole, and guiding cone top is cylindrical structural, and bottom is inverted round stage structure, interior
Portion has the through hole that aperture tapers into from top to bottom, and the through hole lower end diameter is identical with center hole；The guiding vertebra
Body upper end edge has fillet, and positioning cap has the filleted corner being coupled with being oriented to centrum upper end edge.
Further, the center hole hole wall has rubber ring.
Further, the guiding cone upper end has flange.
Beneficial effects of the present invention：
1. positioning cap, can be by orienting cap center hole and guiding cone lower end with being oriented to centrum in the case where coupling
Circular hole determines puncture path, the target area that ventriculoscope is extremely performed the operation along default Route guiding；
2. behind the target area for reaching operation, positioning cap and guiding cone are departed from into coupled relation, ventriculoscope has to wear
The adjustable space of the taper of axle, the circular hole that cone lower end is directed to before puncture are placed on brain tissue surface centered on thorn path, from
And ventriculoscope is disturbed with the brain tissue minimized, maximized range of observation is obtained.
Brief description of the drawings
Fig. 1 is the structural representation of stereotaxis guide of the present invention；
Fig. 2 is the structural representation of positioning cap；
Fig. 3 is the structural representation of guiding cone；
Fig. 4 is the schematic diagram that ventriculoscope rotates in stereotaxis guide；
In figure, positioning cap 1, guiding cone 2, center hole 11, through hole 21.
Embodiment
As shown in figure 1, a kind of stereotaxis guide, fixed suitable for existing stereo brain orienting instrument and frameless solid
To；Including positioning cap 1 and guiding cone 2, the positioning cap 1 is provided with center hole 11；Tied for cylinder on the top of guiding cone 2
Structure, it is allowed to be applied on the guide base of existing stereo brain orienting instrument or the fixed support of uncontrolled junction, under
Portion is inverted round stage structure, convenient to be directed at appointed part, and inside has the through hole 21 that aperture tapers into from top to bottom；The guiding
The upper end edge of centrum 2 has fillet, and positioning cap 1 has the filleted corner being engaged with being oriented to the upper end edge of centrum 2.
In use, ventriculoscope puncture path is determined by the stopper and guide of stereotactic apparatus so that ventriculoscope edge
Default path is advanced into the target area of operation, and can follow to path the areas case for detecting different depth；Then removal stops
Only device, the ventriculoscope in guide through hole 21 can be turned to along the side wall of through hole 21, as shown in Figure 4.Guiding cone 2
Inner chamber, i.e., the through hole 21 tapered into from top to bottom can provide the adjustable space of a cone shape, ventriculoscope for ventriculoscope
Mirror body be located at the top of cone space, during close to brain surface, the camera lens of front end adjusts in any case, and mirror body is to brain surface
Agitation all very littles, the depth for going deep into brain tissue with mirror body increases, and its adjustable space becomes big, i.e. the more focus in deep, observation
Scope is bigger, so as to be disturbed with the brain tissue of minimum, obtains maximized range of observation.
And work as the time got lost in operating process, positioning cap 1 need to only be slid onto to the coupling position of guiding cone 2,
Ventriculoscope recovers to original puncture path, and now carrying out visualization using the image of navigation or surgical planning comments
Estimate.When the design of fillet can avoid guide pin activity by it is locked the problem of.
Similarly, guide is placed on the fixed support of uncontrolled junction, will after the operation for completing positioning and guiding
The position locking of guide, you can realize above-mentioned same function.
As preferable technical scheme, the upper end of guiding cone 2 has flange, the fixed work of auxiliary guide base
With.The hole wall of center hole 11 has rubber ring so that has higher frictional force between positioning cap 1 and ventriculoscope, avoids
It is relative to slide.
