Puncture needle top both sides are provided with guide post, and guide post is located in guide chute respectively；
The scale grating is fixed on arbitrary guide post and is located in corresponding guide chute, the grating reading head position
In the guide chute corresponding with scale grating.
What is reached has the technical effect that：When anesthetic puncture is done using this device, anaesthetic puncture needle is arranged on into puncture needle first
On top, baffle plate is lain in into patient body-surface then, the puncture action of puncture needle is now realized by rotating push rod, is punctured through
As bar top and puncture needle top are flexibly connected in journey, push rod top top is with the activity clamping of push rod lower end so push rod is rotated
When puncture needle will not also rotated；During inserting needle, scale grating is moved down puncture needle therewith, phase that grating reading head is inswept
The scale grating answered simultaneously records depth of needle so that operator can accurately control puncture needle depth of needle.
Used as the further improvement of this programme, the guide chute two ends that the scale grating is located are along scale grating movement side
There is chute two to being extended.The design can be effectively ensured puncture needle during inserting needle, and scale grating length disclosure satisfy that
Depth of needle.
Used as the further improvement of this programme, the baffle plate arranges one layer with patient contact face silicagel pad.This sets
Meter can reduce extruding of the baffle plate to patient body-surface.
Used as the further improvement of this programme, the cross section of the push rod top is " recessed " shape, and its slot opening is upwards, recessed
Along the block for extending internally is provided with, push rod lower end surrounding is provided with the concave inward structure with groove match to trough rim so that
Push rod top can be rotated around push rod lower end.
Used as the further improvement of this programme, the puncture needle comes directly towards cross section for " recessed " shape, and its slot opening downwards, is worn
Pricker comes directly towards and comes directly towards clamping with push rod.
Used as the further improvement of this programme, the groove inner wall of the puncture needle top is provided with elastic rubber fitting.Design bullet
Property rubber cushion purpose be in order that puncture needle can be relatively stable installed in puncture needle top groove in.
The beneficial effects of the utility model：This programme is formed based on the principle design of syringe, by sleeve pipe and push rod
Between screw thread coordinate and realize the steady inserting needle of puncture needle, while being scale grating by the grating scale sensor on sleeve side walls
Depth of needle is measured with grating reading head so that operator can realize the steady inserting needle of the fixation of puncture needle and depth of needle
Precise control.
