Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
With reference to Fig. 1-3, a kind of marrow puncture needle, including: needle guard 1, nook closing member 2 and stop collar 3；The head end of described nook closing member 2 is provided with puncture portion 21, and described nook closing member 2 and needle guard 1 are respectively equipped with the first connecting portion 22 and the second connecting portion 11 cooperated；Described nook closing member 2 and needle guard 1 are connected with each other by the first connecting portion 22 and second 21 length directions along nook closing member 2 of connection, make described needle guard 1 be sheathed on the outside of described nook closing member 2 and expose described puncture portion 21.
The end of described needle guard 1 and nook closing member 2 connects a grip part 12,23 respectively；Described first connecting portion 22 includes that one is arranged at the grip part 23 of described nook closing member 2 and is connected the projection 221 of side with nook closing member 2, and the periphery of described projection 221 is respectively provided on two sides with the first limited block 222.
Described second connecting portion 11 includes the grip part 12 being arranged at described needle guard 1 containing cavity 111 away from described needle guard 1 side, the inwall both sides of described containing cavity 111 have unidirectional draw-in groove 112, and described first limited block 222 coordinates with described unidirectional draw-in groove 112 contact clockwise.
When medical personnel start to puncture, nook closing member 2 is inserted in needle guard 1, make projection 221 insert in containing cavity 111, then rotate clockwise the grip part 23 of nook closing member 2 so that the first limited block 222 coordinates with unidirectional draw-in groove 112 contact clockwise.Now, nook closing member 2 and needle guard 1 installation, the puncture portion 21 of nook closing member 2 is exposed to the outside of needle guard 1.Mounted nook closing member 2 and needle guard 1 are carried out puncturing operation to patient by medical personnel, and when nook closing member 2 arrives affected area, piercing step completes.
Afterwards, need to be sampled step.During sampling, need to move nook closing member 2 relative to after needle guard 1 so that the sampling portion 13 of needle guard 1 front end carries out cutting sampling to the pathological tissue of affected area.In traditional sampling procedure, need from needle guard 1, take out nook closing member 2 completely, again nook closing member 2 is inserted after then stop collar being installed on needle guard 1.The step for the most loaded down with trivial details, and need frequently touching nook closing member 2 and needle guard 1, easily cause the deviation puncturing direction, and add the duration of whole puncturing operation.
In order to solve this problem, with reference to Fig. 4-6, in the present embodiment, described stop collar 3 longitudinally has the through hole 31 of one and the described corresponding size of nook closing member 2 along it, and the outer surface of described limiting section 3 longitudinally has the groove 32 of a described through hole of connection 31 along it.Therefore, when sampling procedure, medical personnel have only to move nook closing member 2 relative to after needle guard 1, by groove 32 and nook closing member 2 clamping of stop collar 3, so that the through hole 31 of stop collar 3 is arranged in the outside of nook closing member 1, just completing the sheathed installation of stop collar 3 and nook closing member 2, the described puncture portion 21 made is moved rearwards by along the length direction of nook closing member 2 and houses to described needle guard 1.Therefore, medical personnel just can complete the installation of stop collar 3 without being taken out completely by nook closing member 2, shortens the time puncturing sampling, it also avoid and takes out the deviation puncturing direction caused again insertable into nook closing member 2 after nook closing member 2 installs stop collar 3.
Described stop collar 3 is fastened in the outside of described nook closing member 2 by this groove 32 and through hole 31, and its two ends are connected respectively with respectively with described first connecting portion 22 and the second connecting portion 11.
Further, the one end side of described stop collar 3 has the first spacing draw-in groove 33 and the second spacing draw-in groove 34 of mutual angle in 90 °；The length of described first spacing draw-in groove 33 is more than the length of the second spacing draw-in groove 34；By the length that the first spacing spacing draw-in groove of draw-in groove 33 or the second 34 and described first limited block 222 clamping, i.e. puncture portion 21 described in adjustable are moved rearwards by along the length direction of nook closing member 2.Medical personnel can by need sampling tissue number, unrestricted choice is by the first spacing spacing draw-in groove of draw-in groove 33 or the second 34 and described first limited block 222 clamping.
The other end side of described stop collar 3 is provided with the second limited block 35 of mutual angle in 90 °；Described second limited block 35 coordinates with described unidirectional draw-in groove 112 contact clockwise.So that the two ends of stop collar 3 coordinate with nook closing member 2 and needle guard 1 contact respectively, it is ensured that the mounting stability of stop collar 3 and installation strength.
With reference to Fig. 7-8, in the present embodiment, described marrow puncture needle also includes an orientation sleeve pipe 4, and it is sheathed on the outside of described needle guard 1, and its length is less than the length of described needle guard 1.One end of described orientation sleeve pipe 4 is provided with slot 41；One end that the grip part 12 of described needle guard 1 is connected with needle guard 1 has and the rib 14 of described slot 41 grafting.
In piercing process, this orientation sleeve pipe 4 enters puncture position also with needle guard 1, after sampling terminates, by releasing needle guard 1 and the clamping relation of orientation sleeve pipe 4, just can be in the case of taking out nook closing member 2 and needle guard 1, orientation sleeve pipe 4 is stayed site of puncture, when medical personnel need to carry out secondary sample, can again be sampled in directly nook closing member 2 and needle guard 1 being reinserted human body along the direction orienting sleeve pipe 4.Without again puncturing, reduce the misery of patient, also reduce the risk of puncturing operation.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
