  • Patent number: 10207057
    Abstract: A syringe includes a barrel and a rotatable element on the barrel, for example, at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle is held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. The barrel and plunger may be configured to cause the barrel to rotate as the plunger moves along the length of the barrel. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.

  • Patent number: 10099244
    Abstract: The present invention provides actuation mechanisms that incorporate a transmission assembly that allows the mechanisms to cause actuation of workpieces according to a plurality of transmission modes (e.g., at least one forward transmission mode and at least one reverse transmission mode) on demand. Motion, direction, and/or force can be controlled by selecting the corresponding transmission mode. The mechanisms preferably are trigger-actuated by hand (i.e., manually) to cause movement of a workpiece in a desired direction. Desired directions can be linear or nonlinear. The same hand used for trigger action can also be used to change transmission modes in many modes of practice, even while using substantially the same grip used for trigger actuation. In other instances, actuation can be automated rather than manual. Preferably, both actuation and witching among transmission modes can be accomplished with one hand, even while maintaining substantially the same grip that is used for actuation.

    Abstract: A dispenser for viscous, extrudable materials uses a sprocket-driven push chain that is drawn from a chain magazine responsive to actuation of a user trigger. The sprocket for the chain is driven by a toothed wheel, which is driven by a first, ratcheting drive pawl, which is actuated by the trigger. A second ratcheting locking pawl prevents the toothed wheel and hence the chain sprocket from rotating backward when the trigger is released. A single “button” or actuator can be actuated by one hand of a user while the user's other hand grasps a chain retractor to pull an extended chain back to a starting position whereat the dispenser can be reloaded.

A fastening structure for attachment of a container (300) is formed on the adapter substantially along a proximal direction (C) contrary to the feed direction (A). As a result various types of containers can be fastened to the machine without the need to change the mechanism of the device. The container can be provided on both ends with identical external threads and can be closed by closure caps in order to enable intuitive handling. In order to improve access to points which are difficult to reach, the container may be in the form of a curved pipe or may be formed flexibly. The piston rod (200) of the discharge device is then also formed flexibly.

  • Patent number: 8727185
    Abstract: A dispensing device is described. The dispensing device can include a body comprising a downwardly extending, elongated handle, at least one plunger slidably coupled to the body, and a trigger pivotably coupled to the body at a pivot point. The trigger can include a trigger portion extending downward from the pivot point and a transfer arm extending above the pivot point. The dispensing device can also include an actuator for engaging and advancing the at least one plunger in an axial direction and an elongated linkage extending axially and transmitting motion from the transfer arm to the actuator. The actuator can be positioned behind the handle and the linkage can cause the actuator to move forward axially when the trigger portion is pulled.

  • Patent number: 8721600
    Abstract: A delivery gun for discharging bone cement from a cartridge that includes a piston. The gun has a casing from which a drive rod and a disk extend. A drive assembly advances the drive rod and disk so that disk displaces the piston causing the discharge of cement. The drive assembly includes plural links that are pivotally connected to a trigger. The links are displaced in response to the manual displacement of a trigger. One of the links is configured to selectively engage the drive rod. When this particular link is engaged with the drive rod and displaced, the drive rod the drive rod is advanced at a first speed. When this link does not is not engaged with the drive rod, the drive rod is advanced by another link at a second speed.

  • Publication number: 20140084022
    Abstract: An assist assembly incorporated into a dispensing gun supporting an elongated cartridge containing a volume of a flowable material. An internally collapsible seating end of the cartridge is engaged by a rod and forward most plunger of the gun in order to force a flowable material through a forward disposed nozzle of the cartridge. A body contains a compressible spring and is mounted to the plunger so that the body contacts the internally collapsible seating end of the mounted cartridge. Forward advancing of the plunger results in a continuous force application by the spring in order to continuously and evenly dispense through the nozzle the flowable material. A secondary spring is mounted between a forward end of the cartridge from which the nozzle projects and an opposing forward end of the gun for additionally assisting in applying a controlled force discharge of fluid from the cartridge.

  • Patent number: 8672193
    Abstract: The invention relates to a dispenser for discharging at least one component. Said dispenser comprises a base body (100) and an advancing element (300) that can be slid. The advancing element (300) acts upon a container having the component so that the component is discharged from the container by means of an advancement of the advancing element (300). The advancing element (300) comprises teeth (321) in the advancing direction. An actuating lever (400) can be swiveled relative to the base body (100) between an initial position and an activated position. The actuating lever comprises one or more teeth (421), which are engaged with the teeth (321) of the advancing element when the advancing element (300) is advanced.
