Method and apparatus for resecting bone from an ulna in preparation for prosthetic implantation

A bone resection guide, particularly for an ulna, utilizes anatomical reference points of the ulna to establish an optimal position for a prosthesis. The bone resection guide provides a guiding instrument that allows a surgeon to remove only bone that needs to be removed for precise placement of the end prosthesis. A method of resecting bone from the ulna in preparation of prosthetic implantation using the bone resection guide matches an elbow axis finder with a particular size of an ulna fossa of the patient. Once matched, a sized resection template, directly related to the shape of the prosthesis, is used as a resection guide. Incorporated into the bone resection guide are known anthropometric qualities when providing resection surfaces. This enhances the probable position of the implant.

Knee prosthesis with extended range of motion

In a knee prosthesis, the condylar surfaces of a femoral component engage corresponding articular surfaces of a tibial component along prescribed tracks of predetermined curvature which enable relative rotation between the femoral component and the tibial component about a longitudinal axis during articulation of the knee prosthesis, and at least the condylar surfaces or the articular surfaces are flared in a direction away from corresponding articular surfaces or condylar surfaces along engaged posterior and anterior portions of the condylar surfaces and articular surfaces to provide an increased area of contact in deep flexion and in extended hyperextension for reducing contact stresses and concomitant wear while militating against unwanted distraction of the knee prosthesis. In addition, the radius of curvature of the condylar surfaces is reduced along posterior portions of the condylar surfaces to further avoid distraction of the knee prosthesis in deep flexion, thereby enabling deep flexion with greater ease and without excessive contact forces between the femoral component and the tibial component in deep flexion.

Long-stroke two-dimensional nano worktable system with angle compensation function

The invention discloses a long-stroke two-dimensional nano worktable system with an angle compensation function. A six-degree-of-freedom micro table designed on the basis of a piezoelectric ceramic actuator and a soft hinge chain carries out comprehensive compensation of linear positioning and angle errors on a long-stroke two-dimensional nano worktable. A driving mode that a stepping motor and a ball screw are combined is adopted, so a long-stroke two-dimensional nano worktable has a large pitching angle, a deflection angle and roll angle errors, and positioning precision is of micron size. The six-degree-of-freedom micro table has nanoscale linear positioning precision and millisecond-level angle positioning precision. The long-stroke two-dimensional nano worktable and the six-degree-of-freedom micro table are combined to form the long-stroke two-dimensional nano worktable system. Under control of a closed-loop control system, the six-degree-of-freedom micro table carries out the comprehensive compensation of the linear positioning errors and the angle errors on the long-stroke two-dimensional nano worktable, so two-dimensional long-stroke nano positioning is achieved.
