In order to achieve the above object, a kind of safety type single use biopsy sampling puncture needle designed by the present invention, it
Including needle tubing and needle stand, positioning protective sleeve is provided with needle tubing, the positioning protective sleeve is hollow tubular structures, with sealed tube
The upper and lower end face of mouth, upper and lower end face is provided with the through hole for being available for needle tubing to pass through, and positioning protective sleeve is moved up and down along needle tubing；Positioning is protected
Jump ring and jump ring support are provided with sheath, the jump ring support is made up of upper jump ring support and lower circlip support, upper jump ring support
Upper end be fastened in the through hole of positioning protective sleeve upper surface, the lower end of lower circlip support is fastened on positioning protective sleeve lower surface
In through hole, upper and lower jump ring support is provided with the through hole for being available for needle tubing to pass through；Support structure has been extended downwardly on upper jump ring support
Part, lower circlip support has upwardly extended lower support member；The bottom of the jump ring is bilayer that is parallel up and down and linking together
Structure, the double-deck subsurface is provided with the through hole with needle tubing slide fit, and double-deck face layer is parallel bars slot structure,
The width of parallel bars slot structure and the equal diameters of subsurface through hole；A core shift has been upwardly extended on the bottom subsurface of the jump ring
Bar, the top of core shift bar is provided with the non-close through hole for being available for needle tubing to pass through, and the width at the non-close via openings is less than should
Non-close through-hole diameter；The center of core shift bar top non-close through hole is centrally located at same with through hole on the subsurface of jump ring bottom
On centrage；The subsurface of the jump ring bottom is located between the lower surface of upper supporting member and the upper surface of lower support member,
And lower support member comes close to or in contact with the lower surface of jump ring bottom subsurface, upper supporting member is upper with jump ring bottom subsurface
Surface comes close to or in contact with, and the upper and lower supporting member is respectively positioned at the two ends of jump ring bottom subsurface length direction.
The structure of positioning protective sleeve may also is that in present invention design：The positioning protective sleeve is by upper lid and body
Composition, the body is side and bottom lock, the hollow cavity structure of upper end open, and upper lid and body clamping or snapping are simultaneously sealed
The opening of body is closed, body bottom portion and upper lid are provided with the through hole for being available for needle tubing to pass through；
The structure of jump ring support may also is that in present invention design：The upper and lower jump ring support is connected by support bar
It is integral, supporting member and lower support member are extended with support bar；Or the upper support that upper jump ring support is extended downwardly
Component, the upwardly extending lower support member of lower circlip support is fixedly connected with support bar.
Preferably, the parallel bars slot structure is made up of two parallel levers, the channel direction being made up of the lever with
The length direction of jump ring bottom subsurface is consistent, the equal diameters of the width between two levers and subsurface through hole.
As further preferred, width of the distance between the end of two parallel levers less than lever mid portion
Degree.
Preferably, the lower support member is located at the left side of needle tubing, upper supporting member is located at the right side of needle tubing.
Preferably, connecting to form the U-shaped double-decker in side by end between the levels of jump ring bottom.
Used as further preferred, the U-shaped double-deck connection end in jump ring bottom is located at needle tubing left side, the core shift bar on jump ring
To the left side of needle tubing, the opening of core shift bar top non-close through hole is towards needle tubing left side.
Preferably, colour code scale is made every 1cm on needle tubing, it is convenient to confirm that needle tubing enters depth in patient body.
When the safety type single use biopsy sampling puncture needle of the present invention is used, needle tubing is sequentially passed through under positioning protective sleeve
End face through hole, lower circlip rack ventilating hole, jump ring bottom subsurface through hole, parallel bars groove, core shift bar top non-close through hole, upper jump ring
Rack ventilating hole, positioning protective sleeve upper surface through hole, are then pierced in patient body, now jump ring jump ring bottom subsurface through hole,
Core shift bar top non-close through hole, and under the position-limiting action of needle tubing left and right sides supporting member it is vertical with needle tubing.While needle tubing
In piercing process, jump ring is acted on by needle tubing left and right sides supporting member, and its bottom is limited at the lower end of supporting member
Between face and the upper surface of lower support member；After puncture is finished, positioning protective sleeve is promoted to needle point direction, needle point is retracted into positioning
In protective case, when needle point leaves core shift bar top through hole, jump ring occurs in the presence of the support force upwards of lower support member
Lateral deviation, jump ring bottom inclines with needle tubing, and the parallel bars groove of through hole and upper strata on the subsurface of jump ring bottom is stuck by needle tubing, makes needle tubing
One is formed with jump ring, when positioning protective sleeve continues to be pushed away to needle point direction, namely needle tubing is when pulling down, and lower support is received in jump ring bottom
Component resistance upwards, needle tubing cannot be moved with jump ring, and needle tubing is limited in positioning protective sleeve；And work as needle tubing and push up
When, jump ring bottom cannot be moved by the downward resistance of upper supporting member, needle tubing with jump ring, and needle tubing is limited at positioning protective sleeve
It is interior, it is achieved thereby that needle point both will not be passed from the through hole of positioning protective sleeve lower surface, also will not be from positioning protective sleeve upper surface
Through hole pass, by the way that needle point position is stuck in positioning protective sleeve, it is to avoid needle point is exposed, cause unnecessary damage.
Therefore, it have simple structure, it is reasonable in design and easy to use the features such as.
