Fine needle aspiration cytology device syringe holder
First Claim
1. A manually operated aspirating device used in combination with a conventional needle and syringe with plunger comprising:
- a) a body into which the syringe is received via the side thereof, said body having at least one collar formed thereon for attaching said syringe to said body;
b) a slide slidably attachable to said body, said slide having a slot formed thereon for releasably engaging said plunger, said slide being so attachable to said body such that when said syringe is attached to said body, said slide may selectively position said plunger relative said syringe;
c) a hand grip formed to said body distal of the proximal end of the syringe;
d) said slide comprises a generally U-shaped member having a closed end and a pair of generally parallel arms, said slot for releasably engaging said plunger being formed at the closed end of said generally U-shape;
e) said body includes first and second channels formed therein for slidably engaging a respective one of said pair of arms.f) a trigger member depending downwardly from a lowermost one of said pair of arms of said generally U-shaped member, said trigger member being so attachable to said generally U-shaped member that when said generally U-shaped member is slidably attached to said body and handgrip, a generally gun-like structure is formed, said trigger providing means for allowing a user to actuate said slide relative said body; and
g) wherein during use the hand of the user is placed in a forward position wherein the index finger of a user'"'"'s hand is oriented toward the target tissue and is positioned from 1 inch to 4 inches proximal the tip of said needle.

Abstract
A fine needle aspiration cytology device for extracting tissue samples for cytologic evaluation is disclosed. The device comprises a handle and generally U-shaped slide member with trigger attachable thereto. The handle is designed and configured to releasably engage a conventional syringe. The slide is designed to slidably engage with the handle and is provided with a slot at the base thereof for retaining the plunger of the When interconnected, the slide may move in forward or rearward positions relative the handle and further, when interconnected with a syringe, may selectively control the axial position of the plunger relative the syringe. In a preferred embodiment, the device is further provided with a manually adjustable locking detent mechanism that may releasably maintain the handle and slide in rigid connection.
