To achieve the above object, simplified oriententation ventricular puncture device of the present utility model includes guide-localization support and leads
To abutment sleeve, wherein guide-localization support is in " ㄩ " shape frame structure, and the guide-localization support is erected by integrally formed first
Straight bar section, horizontal bar segment, the second vertical bar segment are constituted, and the first vertical bar segment, the second vertical bar segment are vertical with horizontal bar segment,
The end of the first vertical bar segment is fixedly installed spill locating button, and the end of the second vertical bar segment has been wholely set guide-localization set
Cylinder, the guide-localization sleeve is vertical with the second vertical bar segment and parallel with horizontal bar segment, is provided with guide-localization sleeve flexible
Sleeve pipe, the telescopic tube can be provided with locking device and determine so as to be oriented in being slided in guide-localization sleeve on guide-localization sleeve
Position sleeve is fixed with the relative position of telescopic tube.
Further, the first vertical bar segment is identical with the second vertical bar segment length, is 200mm, and horizon bar segment length is
250mm；
Telescopic tube length is 50mm, and guide-localization length sleeve is 20mm, and the external diameter of telescopic tube is fixed less than being oriented to
Position sleeve diameter；
Locking device on guide-localization sleeve includes screw thread through hole and tightening nut, is set in screw thread through hole
The tightening nut coordinated with it is put, the position that screw thread through hole and tightening nut are located on guide-localization sleeve is erected with second
The end of straight bar section is relative；
Groove I is provided with guide-localization sleeve, groove II, groove I and groove II width phases are provided with telescopic tube
Together, it is all higher than the diameter of puncture needle.Telescopic tube length (50.0mm) is more than guide-localization sleeve (20.0mm), and device is used
304 medical stainless steels are made.
The beneficial effect of the utility model simplified oriententation ventricular puncture device is：Simple structure, simple operation, low cost
It is honest and clean, operation progress can be accelerated and can be accurately positioned, while the sliding extension being made up of guide-localization sleeve and telescopic tube
Structure can facilitate to be extended according to different situations in art and position, and further improve the accuracy of guide-localization, it is adaptable to not the same year
Age crowd, it is to avoid the negative consequence that " blind to wear " brings in the past, in addition, by guide-localization sleeve and the groove of telescopic tube
Structure, exits after the completion of puncture guide-localization support, further facilitate the operation of operation.

Specific embodiment
For ease of the understanding of those skilled in the art, below in conjunction with specific embodiment and accompanying drawing to the utility model
Structural principle be described in further detail.
As Figure 1-3, simplified oriententation ventricular puncture device includes guide-localization support and puncture needle, wherein, it is oriented to
Locating support is in " ㄩ " shape frame structure, and the guide-localization support is by integrally formed the first vertical bar segment, horizontal bar segment, second
Vertical bar segment is constituted, and the first vertical bar segment, the second vertical bar segment are vertical with horizontal bar segment, and the end of the first vertical bar segment is consolidated
Surely be provided with spill locating button, the end of the second vertical bar segment has been wholely set guide-localization sleeve, the guide-localization sleeve with
Second vertical bar segment is vertical, and parallel with horizontal bar segment, and telescopic tube is provided with guide-localization sleeve, and the telescopic tube can be in
Slided in guide-localization sleeve.
Telescopic tube length is more than guide-localization sleeve, and its external diameter is slightly less than guide-localization sleeve diameter so that flexible
Sleeve pipe can the freely smooth slip in guide-localization sleeve, the gap between the two is unsuitable excessive, should be maintained at a rational model
In enclosing so that telescopic tube is consistent substantially with the axis of guide-localization sleeve, so as to ensure the accuracy of guide-localization.
