Abstract: An ambidextrous locking clamp system for providing a user the ability to use the right or left hand to engage and disengage a ratcheting means on the clamp. The clamp has hingedly connected first and second elongated members each with a finger engaging member arm, a finger engaging member, a working head, and a latching member featuring ratcheting teeth. The teeth face each other in a direction parallel with a longitudinal axis of the clamp. The teeth are engaged by moving the finger engaging members toward each other in an engaging motion, and are disengaged by sliding them in a disengaging motion perpendicular to the engaging motion with opposing force applied to the finger engaging members. A space is defined between the finger engaging member arms and the finger engaging members. The latching members extend into the space from where the finger engaging members transition from their corresponding finger engaging member arms.

Abstract: An improved surgical stapling apparatus containing a locking mechanism to prevent reactuation of the apparatus, the locking mechanism comprising a resilient clip having a hook which is engagable with a locking notch on the cam bar retainer. The resilient clip is initially held in a non-engagable position by means of a movable chock. When the stapler is actuated for the first time, the cam bar retainer pushes the chock into a subsequent position where the chock no longer blocks the resilient clip. The resilient clip then moves to a position where the hook is engagable with the locking notch. Once the cam bar retainer is retracted it can no longer be reactuated.

Abstract: A stapler, particularly for suturing skin wounds or incisions, is disclosed which comprises a channel in which a driver is advanced by a slide in the direction of an anvil surface. A staple magazine which extends substantially parallel with the driver includes a curved section which opens into the channel to deliver staples into the channel for engagement by the driver. During forward displacement of the driver, a projection on the driver presses a leaf spring to which the anvil surface is connected. The anvil surface at the forward end of the leaf spring is thereby brought into its operating position and is automatically moved back into its retracted position upon release of the spring after the driver is retracted. The curved section in the staple magazine enables the stapler to have a slim profile which does not obscure the working area during a stapling operation. After completion of a stapling operation, the anvil surface is automatically retracted from a closed, implanted staple.

Abstract: A portable electric stapler wherein a bladelike impeller is reciprocable by the armature of an electromagnet which is energizable a selected number of times so that a staple which is introduced into a housing channel in front of the impeller is gradually driven into a workpiece. The magazine for staples and that part of the housing which defines the channel are movable relative to the impeller between a first position in which a pusher can expel a staple from the magazine into the channel and a second position whereby the impeller separates the foremost staple from the stack of coherent staples in the magazine. The impeller blocks the outlet of the magazine during the intervals between successive energizations of the electromagnet to thus prevent entry of a fresh staple into the channel before the driving of the preceding staple into the workpiece is completed. The rearward movements of the armature and the impeller are braked by a pneumatic brake or by a shock absorber.

Abstract: An electro-magnetic tacker, which can carry out a limited number of driving strokes when its main switch is actuated, has a staple magazine pivotal between a blocking position and an operating position. In the operating position of the staple magazine, a staple blocking member blocks the front staple located in the staple magazine and, in the blocking position of the staple magazine, releases this staple for entry into a staple output channel. A coupling element connected to the staple magazine has an engagement portion which, in the switched-on position of an actuator element of the main switch, is in engagement with this. In this switched-on position, the actuator element holds the staple magazine in the operating position via the coupling element, so that the tacker can be lifted off from a workpiece, while at the same time the operating position of the staple magazine and the blocking action of the staple blocking member are maintained.
