Abstract

The utility model discloses a support for aspirator for cell biopsy in the technical field of medical equipment, which comprises a support body. The front end of the support body is provided with a front seat coordinating with the front end of the aspirator tube; the back end of the support body is provided with a recess for fixing the tail wing of the aspirator tube; the rear lower part of the support body is provided with a fixed handle; the lower side of the support body is provided with a slide groove that extends from the front end up to the rear end of the support body. In the slide groove, a slide rod is provided. The lower side of the front end of the slide rod is provided with a movable handle, the tail of the slide rod is located at the rear side of the support body, and is provided with a draw-bar stand matching with the draw bar of the aspirator. At using, the front end of the aspirator tube is fixed on the front seat, the tail wing of the aspirator tube is clamped into the recess, the tail wing at tail end of the upper draw bar of the aspirator is leaned from outside onto the draw-bar stand, the fixed handle is held by the part between the thumb and the index finger of one's hand, the movable handle is triggered by one's index finger, the aspiration operation is done by one hand. The utility model is easy to operate, liberates another hand of an operator, and can lower the difficulty in operation.

Description

Cell biopsy aspirator support

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly the auxiliary device that is used with cell biopsy aspirator.

Background technology

Be diagnosis and treatment disease, often need extracting interstitial fluid, hydrops or relevant cell to chemically examine, during sampling, after putting in place by lancet puncture, extract with aspirator, aspirator has generally comprised piston and cylindrical shell, is connected with pull bar on the piston, the tail end of pull bar and cylindrical shell is equipped with empennage, with handled easily; In when sampling, the barrel front end of aspirator is linked to each other with puncture needle, grip cylindrical shell on the other hand, pull back pull bar on the other hand, the certain vacuum of formation in cylindrical shell, tissue fluids etc. are sucked in the cylindrical shell under vacuum action; From above-mentioned work process as can be seen, need bimanualness by existing aspirator sampling, it operates inconvenience, and the operator is difficult for firmly.

The utility model content

The purpose of this utility model provides a kind of cell biopsy aspirator support, makes more convenient to operate.

The purpose of this utility model is achieved in that cell biopsy aspirator support, comprise supporter, the front end of supporter is provided with the preceding bearing that matches with the aspirator barrel front end, the supporter rear end is provided with the fixedly draw-in groove of aspirator cylindrical shell empennage, the rear lower of supporter is provided with fixed handle, the supporter downside is provided with the chute that always extends to the supporter rear end from front end, be provided with slide bar in the chute, slide bar front end downside is provided with flexible handle, and the tail end of slide bar is positioned at the supporter rear side and is provided with and the suitable drag link bearing of aspirator pull bar.

During this utility model work, aspirator barrel front end and preceding bearing are fixed, the empennage of cylinder back-end snaps in the draw-in groove, empennage with aspirator upper connecting rod tail end abuts on the drag link bearing from the outside simultaneously, and the aspirator cylindrical shell is linked to each other with puncture needle, push the piston of aspirator to front end through pull bar, after puncture puts in place, can hold this utility model by one hand, be about to the tiger that fixed handle is clamped in hands, fasten flexible handle with forefinger, during suction, forefinger to the tiger direction firmly, make flexible handle to fixed handle direction motion,, drive piston and move backward with the relatively-stationary drag link bearing of the flexible handle empennage of push-pull bar tail end backward, and that cylindrical shell is maintained fixed is motionless, thereby finishes aspiration procedure.From above-mentioned work process as can be seen, utilize this utility model to carry out cell biopsy sampling, can realize that by one hand it is easy to operate, liberated operator's another hands, can reduce operating difficulty.

Supporter upside between draw-in groove and the preceding bearing is and the suitable circular arc of aspirator cylindrical shell.This structure can make aspirator fixing more reliable.

Description of drawings

Fig. 1 is this utility model structural representation;

Fig. 2 is that the A of Fig. 1 is to view;

Wherein, 1 chute, 2 fixed handles, 3 drag link bearings, 4 aspirators, 5 draw-in grooves, 6 slide bars, 7 flexible handles, 8 supporters, 9 preceding bearings.

The specific embodiment

As figure, cell biopsy aspirator support, comprise supporter 8, supporter 8 can be involuted by two half blocks, be convenient to die sinking and installation like this, the front end of supporter 8 is provided with the preceding bearing 9 that matches with the barrel front end of aspirator 4, supporter 8 rear ends are provided with the fixedly draw-in groove 5 of the cylindrical shell empennage of aspirator 4, supporter 8 upsides between draw-in groove 5 and preceding bearing 9 can be made and the suitable circular arc of aspirator cylindrical shell, the rear lower of supporter 8 is provided with fixed handle 2 so that grip, supporter 8 downsides are provided with the chute 1 that always extends to supporter 8 rear ends from front end, be provided with slide bar 6 in the chute 1, slide bar 6 front end downsides are provided with flexible handle 7, and the tail end of slide bar 6 is positioned at supporter 8 rear sides and is provided with the drag link bearing 3 suitable with the aspirator pull bar.

During work, the barrel front end and the preceding bearing 9 of aspirator 4 are fixed, the empennage of cylinder back-end snaps in the draw-in groove 5, empennage with aspirator 4 upper connecting rod tail ends abuts on the drag link bearing 3 from the outside simultaneously, and aspirator 4 cylindrical shells are linked to each other with puncture needle, push the piston of aspirator 4 to front end through pull bar, after puncture puts in place, fixed handle 2 can be clamped in the tiger of hands, fasten flexible handle 7 with forefinger, forefinger to the tiger direction firmly, make flexible handle 7 to fixed handle 2 directions motions,, drive piston and move backward with flexible handle 7 relatively-stationary drag link bearings 3 empennage of push-pull bar tail end backward, and that cylindrical shell is maintained fixed is motionless, thereby finishes aspiration procedure by one hand.
