An applicator instrument for dispensing surgical fasteners includes a housing, and an elongated shaft extending from the housing. The elongated shaft has a proximal end secured to the housing, a distal end spaced from the proximal end, and a first axis extending between the proximal and distal ends of the elongated shaft. Surgical fasteners are disposed in the elongated shaft. The surgical fasteners are stacked at an angle relative to the first axis of the elongated shaft. A distal end cap having a surgical fastener dispensing window is secured to the distal end of the elongated shaft. The applicator instrument has a firing system disposed in the housing, and an actuator coupled with the firing system for activating the firing system to dispense the surgical fasteners through the surgical fastener dispensing window.

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen.

Pen needle attachment mechanisms

A needle hub assembly for a pen needle includes a needle hub, an inner shield and an outer cover. The open end of the outer cover is closed by a removable seal to access the needle hub. The needle hub has a body with a shoulder and a tower extending from the body for supporting a cannula. The inner shield fits over the tower and the cannula and includes a flange that has an outer dimension complementing the outer dimension of the needle hub and contacts the shoulder of the needle hub in the assembled condition. The outer cover encloses the needle hub and the inner shield and includes a stop member on an inner surface that contacts the flange of the inner shield to capture the inner shield between the shoulder of the needle hub and the outer cover.

Pen needle assembly

A pen needle assembly () includes a pen needle () with a hub body () having a needle shield () that covers a needle () and can be retracted to expose the needle during injection and return to the extended position after use and locked in the extended position. A spring () is provided to rotate the needle shield after use to a locked position. A locking member () can be provided on the needle shield that cooperates with the hub body () to prevent rotation after use. An attachment mechanism () for the pen needle provides a sensory indication when a needle-bearing hub body () is seated on a pen and limits further rotation of the pen needle relative to the delivery device.

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen. Embodiments include a needle-bearing hub includes a circumferentially oriented flexible tab that engages a radially inward rib on an outer cover to assist in attaching a pen device to the pen needle.

An applicator instrument for dispensing surgical fasteners includes a housing, a firing system disposed in the housing, an actuator coupled with the housing for activating the firing system, an elongated shaft extending from the housing, the elongated shaft having a proximal end secured to the housing, a distal end, and a first axis extending between the proximal and distal ends, one or more surgical fasteners disposed in the elongated shaft, and a distal end cap secured to the distal end of the elongated shaft. The distal end cap has a surgical fastener dispensing window for dispensing the one or more surgical fasteners from the distal end cap. The firing system includes a firing rod that extends through the elongated shaft for dispensing the one or more surgical fasteners from the distal end cap. The firing rod has a proximal section that moves along the first axis of the elongated shaft and a distal section that moves along a second axis that defines an angle with the first axis.

The subject invention provides a safety pen needle assembly which includes: a hub; a needle carrier; a needle fixed to the needle carrier; a shield; and, a first engageable locking arrangement for fixing the shield to the needle carrier. Upon a predetermined extent of distal movement of the shield relative to the hub, the first locking arrangement is engaged such that the shield becomes fixed to the needle carrier. Upon further distal movement of the shield relative to the hub beyond the predetermined extent of distal movement, the shield and the needle carrier move in concert together relative to the hub causing a proximal end of the needle to move distally relative to the hub to a retracted state. Advantageously, the subject invention provides a reliable, low-cost safety pen needle assembly which does not require a spring or other biasing element.
