  • Patent number: 12270214
    Abstract: A mortar applicator includes: a duct; a piston movably mounted within the duct, dividing the duct into first and second variable volume chambers; a pump fluidly connected to the first variable volume chamber; a nozzle operatively connected to a first end of the duct to discharge mortar contained in the first variable volume chamber; and a motor operatively connected to the piston. A rack and pinion assembly operatively connects the motor to the piston and includes a rack configured to drive the piston and a pinion connected to the motor. In a discharge mode, the motor drives the rack and pinion assembly, moving the piston to force mortar through the nozzle opening to discharge mortar from the mortar applicator. In a refill mode, the pump fills the first variable volume chamber with mortar, forcing the piston to retract. The rack moves with the piston in the discharge and refill modes.

  • Patent number: 11857408
    Abstract: A variety of configurations of implant management devices are provided. The configurations provide different combinations of features for maintaining a location of an implant with respect to the device and managing filaments of the implant. One exemplary embodiment of a device includes a generally rectangular-shaped body having an implantable body retainer, an opening disposed a distance apart from the retainer and configured to receive a ligament graft therein, and a fold extending across the body and intersecting the opening. Folding one end of the body towards a bottom surface of the body along the fold can form a filament loop engaging region to hold in tension a filament loop extending from the implant. Additional filament(s) associated with the implant can be managed by various filament retention features. Methods for preparing a ligament graft for implantation by relying upon indicia formed on a surface of the device body are also provided.
