This utility model purpose employed technical scheme comprise that a kind of puncture needle, including sleeve, nook closing member, it
Also include:
Handle, this handle is connected to the top of sleeve, and described handle includes fixed component, fixed component
It is provided with two extension bars；The top half of described fixed component has the first through hole, and the latter half has
Second through hole；First through hole and the connection of the second through hole；The aperture of the second through hole is the aperture of sleeve, the
The aperture of one through hole is more than the aperture of the second through hole；Nook closing member passes from the first through hole, the second through hole successively
Enter in sleeve；
Spring, is located in the first through hole, between the inwall of nook closing member and the first through hole；
Push rod, including the body of rod and the handle of being located at body of rod upper end, the described body of rod is placed in described first through hole
In, and with described spring contact；Described body of rod lower end has groove, and the top of described nook closing member is stuck in recessed
In groove.
Further, sleeve ring for fixing it is additionally provided with between described handle and sleeve.
In technique scheme, also include Anti-stabbing device, the upper end of described Anti-stabbing device and hands
Handle is fixing to be connected, and is flexibly connected between the lower end of Anti-stabbing device 5 with sleeve ring for fixing；Described anti-stab
Hinder two shell fragments being provided with inside device for clamping nook closing member；Described nook closing member is provided with near the position of needle point
Draw-in groove, when nook closing member is extracted out from sleeve pipe, shell fragment snaps in draw-in groove.This utility model has the advantage that
1, the motion of nook closing member is controlled by handle, spring and push rod, it is achieved the control flexible to nook closing member.
When 2, being separated with sleeve by nook closing member, the shell fragment of Anti-stabbing device snaps in the draw-in groove on needle point, from
And entangle needle point, it is to avoid needle pricks operator.
Accompanying drawing explanation
Fig. 1 be this utility model puncture needle the first through hole in unsprung structural representation.
Fig. 2 be this utility model puncture needle the first through hole in pacify spring-loaded structural representation.
Fig. 3 is the enlarged drawing of A in Fig. 1 and Fig. 2.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model puncture needle includes sleeve 7, nook closing member 2, handle 4, push rod 1
With sleeve ring for fixing 6, sleeve ring for fixing 6 is located at the top of sleeve 7, and the bottom of handle 4 is fixing to be connected
There is Anti-stabbing device 5, for being flexibly connected between the lower end of Anti-stabbing device 5 with sleeve ring for fixing 6, example
Such as clamping or threaded.Anti-stabbing device 5 includes two shell fragments 5.1 for clamping nook closing member 2.
Handle 4 includes that fixed component 4.1, fixed component 4.1 are provided with two outwardly directed extension bars
4.2；Top half within fixed component 4.1 has the first through hole 4.3, and the latter half has second and leads to
Hole 4.4；First through hole 4.3 connects with the second through hole 4.4.The aperture of the second through hole 4.4 is sleeve 7
Aperture, the aperture of the first through hole 4.3 is more than the aperture of the second through hole 4.4；Nook closing member 2 leads to from first successively
Hole the 4.3, second through hole 4.4 passes.
It is provided with spring 3 in first through hole 4.3, and spring 3 is positioned at nook closing member 2 and the first through hole 4.3
Between wall, as shown in Figure 2.
Push rod 1 includes the body of rod 1.2 and is located at the handle 1.1 of the body of rod 1.2 upper end, and the lower end of the body of rod 1.2 is put
In described first through hole 4.3, and contact with spring 3；The bottom of the body of rod 1.2 has groove, nook closing member
Top be positioned at groove.
As it is shown on figure 3, nook closing member 2 is provided with draw-in groove 8 near the position of needle point.
When using this utility model, fill according to using position difference to may choose whether with needle point Anti-stabbing
Put.
1, when simple hypodermic punctures, forefinger and middle finger are caught on the extension bar 4.2 of handle 4, with big
Thumb presses the handle 1.1 of lower push-rod 1, and now needle point exposes (push rod will not expose) without pressing needle point
Now puncture, often puncture certain distance and unclamp push rod 1, now because of needle tip retracts, as penetrated cortex
Forward impelling meeting drag minimization, because in needle point retraction sleeve pipe, so other tissue will not be accidentally injured,
As very big in also do not penetrated cortex then resistance, now continue down to puncture by lower push-rod until unclamping after subcutaneous
Push rod, takes out puncture needle, carries out other operations such as putting pipe.
2, when the guiding carrying out various position punctures, forefinger and middle finger are caught on handle, press with thumb
The handle 1.1 of lower push-rod 1, now needle point exposes (push rod without pressing needle point will not expose) and now enters
Row punctures, and under B ultrasonic etc. guides, inspection sees that Needle localization and puncturing tissue are the most errorless, if desired can pine
Open push rod retraction needle point, carry out visiting thorn with needle guard, because so it will not be accidentally injured in needle point retraction needle guard
Its tissue, is confirming that errorless rear continuation punctures to predetermined position, now will set at sleeve ring for fixing 6
Cylinder 7 and nook closing member 2 separate, and being located at the shell fragment in Anti-stabbing device 5 nook closing member 2 is extracted out when can block
At the card grain 8 of needle point, thus clamping nook closing member 2, now, by Anti-stabbing device 5 and sleeve ring for fixing
6 open, when Anti-stabbing device 5 is prevented from the nook closing member 2 extracted out, and the needle point accidental injury to operator,
Now puncture needle sleeve 7 is only left at internal, can continue follow-up to put pipe along sleeve 7 to being built into seal wire
Deng operation.
