A typical bone staple system comprises pins such as stapler pins, which are drilled or fixed in the body via surgery temporarily or permanently depending on the medical need of the patient. Bone staples are predominantly used for neutralization.
Universal fixator clamp
An external fixation system that uses a torquing apparatus and a universal fixator clamp. The universal fixator clamp comprises a proximal head, a screw plate, a first upper clamp plate, a second upper clamp plate, a spring, a first lower clamp plate, and a second lower clamp plate. The first upper clamp plate and second upper clamp plate define at least one bone pin channel and at least one frame rod channel. The first lower clamp plate and second lower clamp plate define at least one bone pin channel and at least one frame rod channel. A central bolt engages with the screw plate to compress the universal fixator clamp when turned by the torquing apparatus. The torquing apparatus has a plurality of arms that engage with complementary recesses in the proximal head to prevent patients from disengaging the clamp once tightened.

Bone staple, instrument and method of use and manufacturing
A new shape changing staple and instrument for the fixation of structures to include bone tissue and industrial materials. This new staple stores elastic mechanical energy to exert force on fixated structures to enhance their security and in bone affect its healing response. This staple once placed changes shape in response to geometric changes in the materials structure, including healing bone tissue. The staple is advanced over prior staples due to its: 1) method of operation, 2) high strength, 3) method of insertion, 4) compressive force temperature independence, 5) energy storing staple retention and delivery system, 6) compatibility with reusable or single use product configuration, 7) efficient and cost effective manufacturing methods, and 8) reduction in the steps required to place the device. In addition to the staple's industrial application an embodiment for use in the fixation of the musculoskeletal system is shown with staple, cartridge, and extrusion handle.

Staple instrument
There is provided a staple instrument for inserting and removing staples from bone. A rotational drive shaft is turned to provide finite adjustments to open and close jaws used to hold and adjust the legs of a staple. A converter coupling converts the rotational motion of the drive shaft to liner motion to operate an articulated linkage system that moves the jaws. The jaws include a sharp edge to engage under a bridge of a staple inserted in bone segments and a convex pry surface that cooperates with the edge to pry a staple from the bone segments when the instrument is pulled away from the bone segments.
