摘要： The present invention is directed toward a plunger provided for use in a nozzle assembly. The nozzle assembly includes an internal chamber with an outwardly tapered portion at one end thereof. The plunger includes a plurality of outwardly curved prongs or legs which mate with an inwardly tapered portion of the internal chamber in order to allow the piston of the injector to be released from the plunger. As a result, the plunger may be removed from the injector when the nozzle assembly is removed therefrom. This plunger may include a frangible portion so that, upon firing, a first driving member of the plunger breaks away from a second driving member of the plunger. As a result of this frangible connection, the first driving member remains lodged in a distal portion of the chamber to prevent reuse of the nozzle assembly.

摘要： An injector nozzle which has a body defining a chamber. A portion of the body has an orifice which communicates with the chamber for allowing fluid to enter into or exit from the chamber. The nozzle body includes at least one depression which is configured and dimensioned to cooperatively engage a tab member of an associated component for coupling thereto. The depression is also configured and dimensioned to positively lock the body to the associated component. The body portion which contains the depression is spaced proximally from the orifice. Also, an adapter for coupling the nozzle to a fluid container. The adapter includes a tubular member having first and second ends and a wall therebetween. The wall includes a passageway therethrough with the first end being dimensioned and configured to cooperatively engage the nozzle. The orifice of the nozzle generally aligns with the wall passageway for fluid communication therebetween. The second end of the adapter is configured and dimensioned to cooperatively engage a fluid container. These devices can be used in combination to provide a system for filling an injector with medicament.

摘要： A safety mechanism for aiding in the prevention of accidental or unintentional discharge of a needleless injection device having a power unit, a housing, a plunger disposed within the housing, a trigger assembly, and a nozzle. The safety mechanism includes a locking member which is disposed at least partially on the exterior of the housing. The locking member works in concert with the triggering assembly to the prevent movement thereof, thereby preventing activation of the power unit to eject fluids through the nozzle. The locking member also works in concert with an interlocking sleeve which prevents activation of the injector when the nozzle is removed therefrom. The safety mechanism also includes a feature for automatically returning the locking member to a locked position after activation.

摘要： A plunger/ram assembly adapted for a hypodermic fluid injector having a nozzle body defining a fluid chamber and an orifice communicating with the chamber. The plunger/ram assembly comprises a plunger adapted to be movably positioned in the chamber and a ram assembly. The ram assembly is operatively connected to the plunger for drawing fluid into and expelling fluid out the chamber through the orifice. The ram assembly includes first and second driving members spaced apart by a preselected free travel distance and a resilient biasing member having a preselected preload. The resilient biasing member is operatively disposed for maintaining the free travel distance when the preload is greater than a force applied to the first driving member. The maximum fluid pressure generated by the plunger/ram assembly is controlled by a free travel distance or gap existing between first and second driving members before the injector is fired. Prior to firing, the gap is accurately maintained during movement of the plunger/ram assembly by a resilient spring member. This arrangement ensures that the injected fluid will be delivered to the patient's body at a desired pressure sufficient to properly pierce the patient's skin or the like.

摘要： A nozzle assembly adapted for a fluid injector having a ram, includes a plunger assembly having first and second driving members. The first and second driving members are apart according to a predetermined first distance. The second driving member is spaced apart from the ram according to a predetermined second distance. The first and second distances are resiliently maintained by a resilient spring member operatively disposed between the two driving members. One of the first and second distances is selected to be the smallest and thereby controls the maximum pressure at which fluid is expelled from the nozzle assembly.

摘要： The present invention relates to new surgical fasteners and methods of using the surgical fasteners. The surgical fasteners of the invention are in the form of tacks and comprise generally an elongate rod, a sharp conical head, a tail, and a transverse locking member extending from the tail above the plane of the rod. The fasteners are inserted into a bodily cavity for tissue and membrane fixation and approximation by the use of tack applicators. The tack applicators of the invention generally comprise an elongate handle, a loading tip and a carrier assembly that is removably inserted into the loading tip. The tacks are inserted and locked into the carrier assembly from which they may be disengaged.

摘要： A nozzle assembly adapted for an injector, includes a frangible plunger. The plunger has a first driving member and a second driving member connected to the first driving member and spaced apart therefrom by a predetermined gap using a frangible bridge. When a predetermined force is applied to the second driving member, it breaks the frangible bridge and moves the second driving member across the gap. This causes the second driving member to ram into the first driving member driving fluid out of the nozzle. Thereafter, as the second driving member is separated from the first driving member, the first driving member remains stuck in the chamber preventing reuse of the nozzle assembly.

摘要： A surgical stapling instrument includes a staple cartridge that may be loaded with surgical staples, an anvil mounted to confront the staple cartridge for deforming staples driven theretoward, and advancer for advancing the staple cartridge from an open position toward the anvil to a closed position for clamping tissue to be sutured therebetween, and a driver for driving the staples from the cartridge toward the anvil through tissue clamped between the cartridge and the anvil. A trigger for operating the driver, and a safety mechanism linked to the advancer preventing the trigger from operating the driver when the cartridge is in the open position but permits the trigger to operate the driver only when the cartridge is in the closed position. In addition, a coupling mechanism can removably mount a head assembly and a handle assembly, with each assembly containing a portion of the advancer and driver. The coupling mechanism can also include a rotatable mechanism for permitting relative rotation between the handle assembly and the head assembly. The advancer includes a clamp lever that articulates first in the forward direction and then in a downward direction. The staple cartridge can include a housing loaded with at least one staple and a comb with at least one tooth. The comb is driven by the driver to drive the staple and can be of varying lengths to compliment the staple.

摘要： An instrument, article and method are provided for minimizing pain during administration by injection of a liquid, such as, an anesthetic. The instrument has a forward end. A lightpipe mounted freely for vibration projects out of the forward end. The article, a single use tip, is composed of a tip sleeve removably mounted on the forward end of the instrument and a tip member removably mounted on the projecting lightpipe to vibrate a preselected injection site on a human or animal. The tip sleeve and tip member are covered by an elastic overmold that enables the tip member to vibrate freely with respect to the tip sleeve and light from the lightpipe to illuminate the injection site. A vibration unit mounted in the instrument is coupled to the lightpipe. The method is carried out by imparting vibrations and illumination via the lightpipe to the tip member.
