Abstract: A bone fixation apparatus and method are provided that allow a user to push bone pins into engagement with bones with more precision and accurate feel as to proper engagement and the clamping forces between the pins and bone over prior devices utilizing applicator guns and the like. Fine tuning of the clamping forces is also contemplated. Compact and highly ergonomic bone fixators are provided which allow the user to remain close to the pin application site during clamping of the pins onto the bone. Significant flexiblity is preferably incorporated by having two adjustably connected positioner bodies which can each mount a pin holder module releasably attached thereto. A fixation system with improved rigidity is also provided by way of independent clamping members for each of a pair of rod mounts on each pin positioner.

Abstract: An anchoring member and packer for use in spinal osteosynthesis systems. The anchoring member can accept a connecting element such as a spinal rod, and is adapted for insertion into bone. The packer provides stability to the anchoring member particularly when the anchoring member is not fully engaged to bone. The anchoring member has a head, anchoring means for engagement to bone, and retaining means for retaining the packer against the head. The packer has a through-orifice for receiving the anchoring member and complimentary retaining means for engagement to the head of the anchoring member.

Abstract: An applicator device for controllable injecting a cement into bones, particularly, in percutaneous vertebroplasty, comprising an elongated body with an inner axial cavity, a guiding block having an inner thread closing a first end of the axial cavity, a rotatable spin having a central outer thread portion and a distal end emerging from an axial cavity through the guiding block, the spin being axially movable within the axial cavity when being rotated, a syringe holder compartment for tightly holding a syringe body within an axial space being in axial continuation of the axial cavity, the syringe holding compartment comprising a hollow body being releasably fastened by fastening means within at least an end portion of said axial cavity, and at least a first axial rib outwardly protruding from the hollow body, the first axial rib fitting within a complementary first axial slot in said end portion of the axial cavity.

Abstract: A closure system for fixing a spinal fixation element to a spinal fixation element receiving body includes a low profile outer locking nut for engaging an outer surface of the spinal fixation element receiving body and an inner set screw for engaging an inner surface of a spinal fixation element. The outer locking nut includes opposed proximal and distal ends, a generally cylindrical, low profile outer surface, an inner surface defining an inner bore, and a spinal fixation element closure surface provided on the distal end. An engagement element is formed on the inner surface adjacent the distal end for engaging an outer portion of the spinal fixation element receiving body so as to close the spinal fixation element to the spinal fixation element receiving body upon tightening of the engagement element. A driving element is formed at the proximal end within a periphery defined by the low profile outer surface and is configured to receive a driving tool to tighten the engagement element.

Abstract: A deodorizer device for deodorizing shoes, includes a container containing deodorizer material, and a dispenser assembly at one end of the container for dispensing deodorizer material. The dispenser assembly includes a feed tube having one end located within the container and the opposite end communicating with one or more discharge openings for discharging deodorizer material laterally of the container. The dispenser assembly further includes an actuator attached at one end to the feed tube and configured to enable the actuator to be inserted into a shoe, when the container is inverted, to stably support the container in the inverted position, and to be pressed against the inner surface of the shoe bottom for discharging a quantity of deodorizer material from the discharge opening laterally into the shoe.

Abstract: An electrically operated flow control valve 100 comprises a can 160 fixed to the upper portion of a valve body 110. A rotor member 130 is equipped inside a can 160, and a stator member not shown in the drawing is equipped to the exterior of the can 160. The can is formed by press-working a metal plate, and a flange portion 164 is formed to the opening. The can 160 is welded onto the valve body 110, and a box nut 180 is used to firmly fix the can to the body, thereby improving the pressure resistibility of the valve.

Abstract: The shut-off device is intended for refillable gas cylinders. In order to be sure that only authorized persons can refill the cylinder, the filling device comprises a non-return valve element (16) which prevents filling and which can only be neutralized using a special magnet (18).

Abstract: In an arrangement and method for adjusting an electromatic gas change valve including: an opening and a closing magnet for operating a valve member of the gas change valve; an armature disposed between the opening and closing magnets and operative for movement with the valve member; and an upper and a lower valve spring engaging the valve member and arranged in opposition to each other under pretension so as to hold the valve member and the armature in an equilibrium position, adjustment means are provided for adjusting the equilibrium position during valve operation wherein the current consumption values of the opening and closing magnets over time are measured and integrals thereof are formed in an evaluation unit and the adjustment means are adjusted until the integrals reach a predetermined value corresponding to the desired equilibrium position.
