A unilateral fixator for adjustment of a first bone portion relative to a second bone portion. The fixator includes a telescopically adjustable strut having first and second ends and a strut axis, and first and second compound joints. The first compound joint is coupled to the first end of the strut and to a first bone clamp, and includes a first gear mechanism controlling linear and rotational motion of the first bone clamp relative to first and second axes while the first bone clamp is engaged with the first bone portion. The first and second axes are generally orthogonal to one another and to the strut axis. The second compound joint is coupled to the second end of the strut and to a second bone clamp and includes a second gear mechanism controlling linear and rotational adjustment of the second bone clamp. The first compound movable joints can rotate about the strut axis.

A bone clamp moving bone segments relative to each other. The clamp comprises a first and second branch and a bridge connecting the first and second branch. The bone clamp may have a first, undeformed state, where the branches may be angled or substantially parallel with respect to each other. The bone clamp may have a second, deformed state, where the branches may be moved from the first state. The bone clamp may be deformed using an instrument such as pliers. When the bone clamp is in the deformed state, the branches may be inserted into bone segments. Thereafter, the instrument may be disengage from the bone clamp and the clamp may return to its undeformed state. While returning to the first, undeformed, state the bone clamp may apply compressive or distraction forces on the bone segments, thereby moving the bone segments relative to each other.

Devices and methods for stabilizing bone. The devices and methods may provide a more balanced proximal and distal compression when stabilizing bone. An exemplary device may comprise a staple member including a bridge connecting a first leg to a second leg. The device also may comprise a resilient arm elongated between a fixed end and a free end, and projecting from the first leg and / or from an end region of the bridge adjoining the first leg. At least a portion of the resilient arm intermediate the fixed and free ends may be inwardly adjacent and spaced from an upper region of the first leg.

The invention discloses a saw blade leveling type clamping-installation bone sawing machine with a sliding plate for feeding. The clamping-installation bone sawing machine comprises a workbench, a machine frame, a saw blade, guide rails and the feeding sliding plate. The guide rails are arranged on the workbench, the feeding sliding plate is arranged on the guide rails through pulleys arranged at the bottom of the feeding sliding plate, and a through groove where the saw blade can penetrate through is formed in the plate face of the feeding sliding plate. Sliding grooves are formed in the two sides of the feeding sliding plate, adjusting lead screws are arranged in the sliding grooves, sliding seats are arranged on the adjusting lead screws and located in the sliding grooves, and a bone clamp is hinged to each sliding seat and can rotate horizontally relative to the sliding seat. The two sides of the upper portion of the machine frame are respectively provided with a leveling mechanism of a driven shaft. Due to the fact that the bone clamps are arranged on the sliding seats and can rotate horizontally relative to the sliding seats, the relative position of the bone clamps on the two sides can be adjusted, and therefore bones in different shapes can be clamped. Due to the fact that the vertical sliding grooves, sliding blocks and leveling bolts are additionally arranged on the machine frame, the levelness of the driven shaft can be adjusted through adjustment of the leveling bolts, and therefore the problem that the saw blade is prone to deviation or being pulled broken is solved.

The invention discloses a pair of reduction forceps. The pair of the reduction forceps comprises at least two bone clamping forceps bodies and a connection rod connecting the two bone clamping forceps. The connection rod comprises a connection rod body, an adjusting rod and a longitudinal adjusting mechanism enabling the connection rod body to move relative to the adjusting rod in the longitudinal direction. According to the reduction forceps, people only need to adjust rotation of a gear so that broken bones can move relatively along the connection rod in the longitudinal direction, and accordingly reduction of the broken bones is achieved. Manual adjustment is not needed, the positions of the broken bones do not need to be fixed, after broken bone reduction is finished, the relative position of the two bone clamping forceps bodies can be locked through the connection rod body, and accordingly the relative position of the broken bones is locked. The situation that the broken bones are dislocated after subsequent operation of an operation is avoided, so that labor intensity of medical staff is lightened, and pains of patients are relieved.
