The instrument for handling biopsies and samples comprises a main body (3) of which the form is similar to that of a syringe, a plunger (4), a recoil means (7), and an element (5) for contacting the sample (2). In order to prevent the suction created by the movement of the recoil means (7) from cancelling out the ejection effect, a small calibrated air inlet (8) is provided to compensate for the volume deficit when the sample obstructs the opening (6) of the suction-ejection tube (10). The ejection of the sample by means of a jet of air can therefore take place in all cases from a plunger position which corresponds to the maximum volume.
L'instrument pour la manutention de biopsies et prélèvements se compose d'un corps principal dont la forme s'apparente à celle d'une seringue, d'un piston, d'un moyen de rappel et d'une partie de contact avec le prélèvement. Pour que le degré d'accomplissement de l'effet de succion provoqué par l'action du moyen de rappel n'hypothèque pas l'effet d'éjection, un micro-canal d'entrée d'air calibré permet de combler le déficit de volume lorsque le prélèvements obstrue l'orifice du canal de succion-éjection. L'éjection du prélèvement par le jet d'air peut ainsi avoir lieu dans tous les cas à partir d'une position du piston correspondant au volume maximum.
