Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of under ultrasound guidance for clearing up the intervention puncture needle for cystis of cyst, abscess.
Background technology
The advantages such as amnio-infusion is little with its wound, good effect, expense are low, be widely used in clinic diagnosis, the sclerotherapy for organ cyst each in human body has good curative effect.At present, the insertion puncture needle that ultrasound guidance uses mainly contains common puncture needle (also known as PTC pin), EV pin etc., but all there is weak point, its major defect has: the first, both are single hole puncture needle, shell all utilizes most advanced and sophisticated single hole Aspiration capsule liquid, without side opening: the second, the former puncture needle nook closing member is real core pin, can not carry out drug injection: three, the latter's puncture needle shell is flexible pipe, easily give a discount, ultrasonic under not easily develop.Therefore, larger for volume and there is many defects containing the Cystis therapeutic of cotton-shaped composition in many rooms, capsule liquid.This just makes existing puncture needle in capsule liquid aspiration procedure, puncture needle shell pin hole easily sticks cyst wall, cause suction not smooth, in cyst, separation and cotton-shaped composition easily block the most advanced and sophisticated unique suction socket of puncture needle shell, very easily cause obstruction, cause capsule liquid to aspirate endless once block, will inevitably curative effect be had influence on.PTC pin can't administration in nook closing member capsule, and rear shell easily gives a discount, and is unfavorable for that nook closing member penetrates again.Therefore the defect of existing puncture needle gets involved completing smoothly of sclerotherapy operation to cyst and brings difficulty, increases medical-risk, reduces operative effect, even causing operative failure, through extensively retrieving, not yet finding ideal technical scheme.
Utility model content
The purpose of this utility model is to solve, and the needle point that the insertion puncture needle that ultrasound guidance that present stage uses uses exists easily gets clogged can not the shortcoming of abundant Aspiration capsule liquid, and the one intervention puncture needle for cystis proposed.
To achieve these goals, this utility model have employed following technical scheme:
A kind of intervention puncture needle for cystis, comprise pin shell, nook closing member is provided with in described pin shell, the outside of described pin shell is provided with one group of graduated ring, it is characterized in that: described pin shell rear end is connected one group of dismountable extension tube, the front end of described nook closing member is provided with the hollow needle of a composition pencil distribution, the hollow needle of described pencil distribution also with pin shell corresponding matching, each described hollow needle is all communicated with described nook closing member, the sidewall of each described hollow needle is equipped with one group of through hole.
On the basis of technique scheme, following further technical scheme can be had:
Described extension tube by two symmetrical arcs coordinate formed columnar structured, the bayonet socket that arc described in one of them is provided with one group of fixture block, another arc is provided with one group of snap-fit engagement corresponding to corresponding fixture block, the outside of each described arc one end is provided with an exterior bayonet slot, is provided with an outer baffle in the outside of exterior bayonet slot; The inner side of the other end is provided with an inner card cage, is provided with an Internal baffle in the outside of inner card cage.
Described nook closing member rear end is flexibly connected one and extends flexible pipe.
Described hollow needle bends to umbrella after stretching out pin shell, and the end of each described hollow needle is provided with tip.
Adjacent two described graduated ring interval 1CM, be thick lines by the graduated ring of front end 5CM backward, the graduated ring at 5nCM place is n bar thick lines, and remaining graduated ring is hachure.
The different thicknesses of described graduated ring and the clear and definite puncture needle depth of needle of design convenient operation person of number.
The utility model has the advantage of: the puncture needle structure that this utility model provides is simple, easy to use, versatility is good, this puncture needle fully can not only take out many rooms cyst capsule liquid to the greatest extent, and can safe ready carry out injection of drug in capsule, the needs of various types of cyst tapping and sclerotherapy can be adapted to.

Detailed description of the invention
As shown in Figure 1, the one that this utility model provides gets involved puncture needle for cystis, and comprise pin shell 1, be provided with nook closing member 2 in described pin shell 1, the outside of described pin shell 1 is provided with one group of graduated ring 1a, it is characterized in that:
A, the most advanced and sophisticated pin hole of described pin shell 1 are inclined-plane pin hole, make puncture shell sharper; Two interval 1CM that graduated ring 1a outside described pin shell 1 is adjacent, be thick lines by the graduated ring 1a of front end 5CM backward, the graduated ring 1a at 5nCM place is n bar thick lines, and remaining graduated ring 1a is hachure; The inside and outside wall that described pin shell 1 front end distance needle point is about 5cm does the process of multiple solutions rough polish, can be screw thread sample, ring-type, frosted shape etc.; Described pin shell 1 rear end is provided with an annular groove 1b.
B, described pin shell 1 rear end are connected one group of dismountable extension tube 3, described extension tube 3 by two symmetrical arc 3a coordinate formed columnar structured, the sidewall of arc 3a described in one of them is symmetrical arranged four fixture block 3e, the sidewall of another arc 3a be provided with four with the bayonet socket 3d of the corresponding snap-fit engagement of corresponding fixture block 3e, the outside of each described arc 3a one end is provided with an exterior bayonet slot 3c, is provided with an outer baffle 3m in the outside of exterior bayonet slot 3c; The inner side of the other end is provided with an inner card cage 3b, an Internal baffle 3n is provided with in the outside of inner card cage 3b, two corresponding exterior bayonet slot 3c of arc 3a and inner card cage 3b corresponding matching form the outer groove of annular and the inner groove of annular, and corresponding outer baffle 3m and Internal baffle 3n coordinates formation outer ring plate and interior annular slab.Be connected on the annular groove 1b place of pin shell 1 rear end by described inner groove and interior annular board after two arc 3a coordinate formation first extension tube 3, second extension tube 3 is by inner groove and the interior annular slab outer ring plate corresponding to first extension tube 3 and outer groove clamping, during use, extension tube 3 is divested, and nook closing member 2 just can stretch out pin shell from the front end of pin shell 1.
