Brief description of the drawings
Fig. 1：The utility model tiny structure EUS puncture needle structure schematic diagram.
Specific embodiment
The technique effect of design of the present utility model, concrete structure and generation is made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
As shown in figure 1, the utility model tiny structure EUS puncture needle, by needle tubing 1, nook closing member 2, inner barrel 3, threeway knot
Structure 4, outer sleeve 6, handle 7 and guide pipe 5 are constituted.One end of the inner barrel 3 is installed by the fixed block with first through hole 32
31, the fixed position-limiting action of the fixed block 31；The other end is provided with the second through hole 33 passed through for needle tubing 1；The needle tubing 1 is successively
Connect through first through hole 32, the second through hole 33 and with three-port structure 4.The nook closing member 2 is located in needle tubing 1 with the phase of three-port structure 4
In the passage of connection.The traversing through end of nook closing member 2 of the three-port structure 4 is detachably connected a connection piece, and the connector is convenient to nook closing member
Draw operation is carried out, the connector is also convenient for being used cooperatively with other structures, and the connector sets with the junction of three-port structure 4
There are sealing ring, main its sealing function of sealing ring, it is also possible to alleviate abrasion when adjacent component is dismantled.
When the nook closing member is punctured in the passage that three-port structure and needle tubing are formed, needle tubing head end forms tiny structure and is more conducive to wear
Thorn and extractable a small amount of diseased tissue, meet the requirement of ultrasonic endoscopic puncture；On the other hand, when nook closing member pulls out needle tubing,
Needle tubing front end can form a tiny structure cavity（The cavity can accommodating portion diseased tissue）, another in three-port structure connect air end
Mouth connection negtive-pressure implement carries out negative pressure extracting, and diseased tissue is temporarily preserved in being constantly pumped into the cavity, after the completion of extraction, by this
After tiny structure EUS puncture needle departs from human body, the diseased tissue that will be extracted is taken out from needle tubing front end.
The front-end and back-end of the inner barrel 3 are arranged with outer sleeve 6 and handle 7 respectively, are set on the outer wall of the inner barrel 3
There is graduation mark, extension elongation that can be easily to guide pipe 5 or needle tubing 1 carries out real-time control（See below description）.The overcoat
The relative slide anteroposterior of inner barrel 3 of cylinder 6, outer sleeve 6 is fixed by the first bolt 61 with inner barrel 3；The front end peace of the outer sleeve 6
The guide pipe 5 that dress stretches out, the guide pipe 5 is enclosed within the outer wall of needle tubing 1.The guide pipe 5 is main to being disposed therein
1 positioning and guiding of needle tubing, support protective effect.The outer sleeve 6 as needed along inner barrel 3 slide into suitable position with
The extension elongation of guide pipe 5 is controlled, after the completion of adjustment, the first bolt 61 is tightened fixed.
The tail end of the handle 7 installs the three-port structure 4 connected with needle tubing 1, the handle 7, needle tubing 1 and three-port structure 4
The common relative slide anteroposterior of inner barrel 3.Positioning sliding block 71 is also arranged with the inner barrel 3, the positioning sliding block 71 is located at outer
On the outer wall of inner barrel 3 between sleeve 6 and handle 7.The positioning sliding block 71 is with respect to the slide anteroposterior of inner barrel 3, the positioning
Sliding block 71 is fixed by the second bolt 72 with inner barrel 3, and positioning sliding block 71 mainly plays positioning supporting role.As needed, slide
Handle 7, now three-port structure 4 and the needle tubing 1 connected with three-port structure 4 together slided together with handle 7, determine needle tubing 1
After extension elongation, adjust the position of positioning sliding block 71 and fixed by the second bolt 72.
Further to improve, the front end of the handle 7 is provided with the arc body 73 of outwardly convex.The convenient use of arc body 73
Person grips.
When using, nook closing member 2 is passed across in the passage that three-port structure 4 is connected with needle tubing 1, the other end of three-port structure 4 with it is big
Gas is connected.Then according to the position of destination organization, by outer sleeve 6 along the slide anteroposterior of inner barrel 3, according on the outer wall of inner barrel 3
Scale, the extension elongation of guide pipe 5 that adjustment is connected with outer sleeve 6, then by the first bolt 61 by outer sleeve 6 and inner barrel
3 fix；Then along the slide anteroposterior handle 7 of inner barrel 3, according to the scale on the outer wall of inner barrel 3, the extension elongation of needle tubing 1 is adjusted,
Positioning sliding block 71 is slid into the front end of handle 7, and handle 7 is fixed with inner barrel 3 by the second bolt 72.Needle tubing 1 and lead
To carrying out puncture working, pull nook closing member 2 after the completion of the position adjustment of pipe 5.The nook closing member external diameter is slightly smaller than the internal diameter of needle tubing, backward
During pull nook closing member, the space that air enters between needle tubing inside and nook closing member outer wall by three-port structure, so as to reduce because of pull
Nook closing member and in the acrogenous suction strength of needle tubing, the tiny structure of formation is when the diseased tissue for needing is extracted, it is to avoid because bearing
The defect that diseased tissue is together extracted together with watery blood that is big and causing is pressed through, in addition when nook closing member pulls out needle tubing, in needle tubing
Front end can form a tiny structure cavity, carry out negative pressure extracting in another air port connection negtive-pressure implement that connects of three-port structure, morbid state
Tissue is temporarily preserved in being constantly pumped into the cavity.After the completion of diseased tissue is extracted, tiny structure EUS puncture needle is taken off
From patient body, the diseased tissue of extraction is taken out from needle tubing front end.
According to the teaching of the present embodiment, those skilled in the art are capable of achieving other the utility model protection model completely
Enclose interior technical scheme.
