A drive assembly for a drug delivery system includes a plunger member configured to engage and move a stopper within a container, with the plunger member having a first position and a second position axially spaced from the first position, a leadscrew configured to move the plunger member from the first position to the second position, and a biasing member configured to bias the leadscrew in a rotational direction, where rotational movement of the leadscrew is configured to move the plunger member from the first position to the second position.

Drive assembly for drug delivery system

The present disclosure generally relates to a retractor device for retracting soft tissue to provide access to a surgical site. The retractor device includes a plurality of blades movable from a first, substantially closed position to a second, substantially open position. Related methods of using the retractor device are also described.

Retractor device and method

A spinal fixation system comprising a bone screw, a body, and a pressure cap. The bone screw may comprise a head at a proximal end and a bone connection element at a distal end. The body may comprise a proximal end, a distal end, a mounting rod receiving channel at the proximal end and a bone screw head receiving channel at the distal end. A proximal end of the pressure cap may comprise two side walls disposed apart from each other and one biasing member on each side wall. A distal end of the pressure cap may comprise a surface operable to contact at least a portion of the head of the bone screw. The pressure cap may be operable to exert pressure on the bone screw when a mounting rod is biased against the proximal end of the pressure cap.

Bone screw systems with pressure caps having biasing members

A rigid modular connector operable to attach to any type of standard male surgical feature that is suitable for large axial loads in both rotational and translational directions while providing accurate tactile feedback. The rigid modular connector includes a handle, a connector rigidly affixed to a proximal end of the handle, and a collar that may slide longitudinally about the connector. The collar may further include one or more leaf springs that are operable to pivot slightly away from or closer to the collar. When the collar slides towards the handle on the connector, the one or more leaf springs may pivot inwardly, locking the collar with the handle in an open position. When the collar slides or the collar slides towards a proximal end of the connector, the one or more leaf springs may pivot outwardly, locking the collar with the connector in a closed position.
