Abstract

An aspiration syringe holder for use in fine needle aspiration is disclosed which includes a holder body for receiving and holding the syringe. Attached to the rear end of the holder body proximate the rear end of the syringe is a handle which extends outwardly therefrom. A trigger is mounted in longitudinal sliding engagement with the holder body and is manually movable from proximate the front end of the syringe rearwardly. A linkage connects the trigger to the syringe piston for transmitting the rearward movement of the trigger to the syringe piston.

Claims

1. An aspiration device comprising:

a syringe of the disposable type having an open rear end, flanges extending transversely therefrom, a piston extending rearwardly from the open rear end of said syringe, said piston having a rear flange, and a needle removably attached to the front end of said syringe; and

an aspiration syringe holder for facilitating the use of said syringe in fine needle aspiration of tissue for cytological examination, said aspiration syringe holder comprising;

a syringe holder body having means for receiving and holding said disposable type syringe;

a handle affixed to said syringe holder body and extending outwardly therefrom proximate the rear end of said syringe, said handle having a rear surface configured for engagement with the palm of a human operator and arranged for applying to said syringe holder body forwardly directed force applied by said human operator to the rear surface of said handle, the rear surface of said handle being located forwardly of the rearwardmost excursion of the piston of said syringe;

a trigger extending outwardly from said syringe holder body forward of said handle;

means for maintaining said trigger in sliding engagement with said holder body such that said trigger is manually movable from a position proximate the front end of said syringe rearwardly toward the rear end of said syringe in sliding engagement with said syringe holder body; and

a linkage attached to said trigger and adapted and configured to engage the piston of said syringe for transmitting the rearward motion of said trigger to the piston, thereby moving the piston rearwardly with respect to said syringe.

2. The aspiration device of claim 1, wherein the means for receiving and holding said syringe includes a forward means for captively engaging the front portion of said syringe and a rearward means for captively engaging the transverse flanges of said syringe.

3. The aspiration device of claim 2, wherein the rearward means includes a groove for receiving therein the transverse flanges of said syringe.

4. The aspiration device of claim 3, wherein said linkage includes a piston plate configured to engage the front surface of the rear flange of said syringe piston.

5. The aspiration device of claim 4, wherein said syringe holder body includes a longitudinal channel having a transversely arcuate bottom for receiving the barrel of said syringe.

6. The aspiration device of claim 5, wherein said linkage includes a rail and said syringe holder body includes a longitudinal slot, the rail being disposed within said slot in sliding engagement therewith.

7. The aspiration device of claim 6, wherein the rail of said linkage and the longitudinal slot of said syringe holder body are T-shaped in cross-section.

8. The aspiration device of claim 4, wherein said syringe holder body includes an upper and a lower portion pivotably connected together proximate the front of said syringe holder body, and further including a rear portion extending from the lower portion and located rearwardly of the upper portion, the upper portion and the rear portion being spaced apart to define therebetween the groove for receiving the transverse flanges of said syringe.

9. The aspiration device of claim 8, and further including releasable locking means for locking the upper portion of said syringe holder body against rotation about the pivotal connection with respect to the lower portion.

10. The aspiration device of claim 4, and further including means for adjusting the longitudinal position of the forward means for captively engaging the front portion of said syringe, to accommodate syringes of various lengths.

11. The aspiration device of claim 4, and further including means for adjusting the longitudinal position of the rearward means for captively engaging the transverse flanges of said syringe, and means for adjusting the length of said linkage, to accommodate syringes of various lengths.

12. The aspiration device of claim 11, wherein said syringe holder body includes a pair of tails connecting the forward means for captively engaging the front portion of said syringe to the rearward means for captively engaging the transverse flanges of said syringe, said trigger being in sliding engagement with the pair of rails.
