摘要：
An injection device, comprising: a syringe cylinder (91), wherein the syringe cylinder provides a fluid reservoir； a plunger (92) configured to be controlled by the device operator and to move within the syringe barrel to load and release fluid from the fluid reservoir in the syringe barrel； and is characterized by further comprising: a) an injection needle (81) that is fixed and operatively coupled to the syringe barrel (91) providing a fluid path for the fluid contained in the syringe barrel to be injected into a target tissue when the plunger (92) is pressed, where the removal or retraction of the needle is independent of the movement of the plunger； b) an elongated sheath (72), comprising an internal light (723) containing the injection needle and having a distal tip containing an opening for the injection needle, where: the sheath can move around the needle injection and the sheath control is independent of the movement of the plunger； and c) a controller (71) for positioning the sheath, comprising: a housing (710), comprising at least a first (715) and a second (716) stop to control the exposure of the injection needle and which are provided inside the housing at a predetermined distance from each other, where detentions may be blocked； a central light (717) in the housing comprising a connection element, where the connection element (713) is configured to move in the central light in the housing and is coupled with the sheath, where the proximal end of the sheath is coupled with the distal end of the connection element so that the movement of the connection element controls the movement of the sheath； and a fitting (711) mounted within the housing configured to move forward towards the distal end of the controller and backward towards the proximal end of the controller, between the stops of the housing, where the installer is operatively connected to the connecting element for guiding the movement of the connecting element in the same direction, whereby the m
