Abstract: A surgical device includes a handle assembly, a drive assembly, and a lockout mechanism. The handle assembly includes a fixed handle and a moveable handle. The moveable handle includes an internal end defining an opening. The opening includes a toothed rack. The moveable handle has an initial position and a full-squeezed position. In the initial position, the moveable handle is spaced-apart from the fixed handle. In the full-squeezed position, the moveable handle is approximated toward the fixed handle. The drive assembly is disposed within the handle assembly and is engaged by the toothed rack. The lockout mechanism is disposed with in the handle assembly and is engaged with the moveable handle to prevent movement of the moveable handle towards the initial position before the moveable handle reaches the full-squeezed position.

Abstract: An explosion-proof system for generating acoustic energy. An exemplary embodiment of the system includes a main housing defining an open housing space and an opening. A cover structure is configured for removable attachment to the main housing structure to cover the opening and provide an explosion-proof housing structure. The cover structure includes an integral head mass. An acoustic energy emitting assembly includes the head mass, and an excitation assembly disposed within the explosion-proof housing structure. An electronic circuit is disposed within the explosion-proof housing structure to generate a drive signal for driving the excitation assembly to cause the acoustic energy emitting assembly to resonate and generate acoustic energy. In one embodiment the acoustic energy is a beam of ultrasonic energy useful for testing ultrasonic gas detectors. A method is also described for testing ultrasonic gas leak detectors using an ultrasonic source.

Abstract: An exemplary embodiment of an acoustic sensor system includes a housing structure, and a miniaturized acoustic transducer mounted in the housing structure. A flame arrestor structure is mounted on or within the housing structure between the acoustic transducer and the external environment, so that ambient acoustic energy passes through the flame arrestor structure before reaching the acoustic transducer.

Abstract: A screw assembly (10) for insertion into a bone region (12A) (12B) includes a screw body (14) and a washer (16). The screw body (14) includes a distal end (218), a proximal end (224), and a distal threaded area (220), and a proximal threaded area (226). The distal threaded area (220) is positioned near the distal end (218) and the proximal threaded area (226) is positioned near the proximal end (224). The washer (16) includes a washer threaded area (238) that engages the proximal threaded area (226) to selectively secure the washer (16) to the screw body (14). With this design, the washer (16) can be selectively attached to the screw body (14) and different sized washers (16) can be alternatively and selectively secured to the screw body (14). As a result thereof, the person inserting the screw assembly (10) can pick the washer (16) size best suited to retain the bone region (12A) (12B) in which the screw assembly (10) is being inserted.

Abstract: A medical fastener (18), preferably bioabsorbable, is used for repairing torn soft tissue, particularly meniscal tissue (16). The fastener (18) can have an enlarged head (22) at the proximate end to engage meniscal tissue (16) adjacent to a tear (14), and a pointed distal tip (21) at the other end to ease insertion of the fastener (18) into the meniscus (16). The shank (20) of the fastener (18) bridges across the tear (14). Opposite ends of the shank (20) are secured in the meniscal tissue (16) by a medical adhesive, preferably bioabsorbable, and preferably at locations remote from the tear (14) so as not to interfere with healing of the tear (14). The fastener (18) can have a blind bore (24) opening through the head (22) of the fastener (18) and extending through the shank (20) to a location close to the tip (21) and generally radial holes (26) communicating between the bore (24) and the exterior of the shank (20).

Abstract: A lancer device that enables a user to draw blood from a patient and discard the used lancet without touching it. The device also has an adjustable tip for selecting the depth of stylet penetration into the patient and a triggering mechanism that utilizes a yoke latch and a leaf spring to discharge the lancet. The lancer also has a dampening feature to reduce vibrations when the lancet is moving.
