Introduction

Ronghua Dong is a notable inventor based in Tianjin, China, recognized for his significant contributions to medical technology. With a total of seven patents to his name, he has focused primarily on the development of bionic joints that enhance the quality of life for individuals needing joint replacements.

Latest Patents

Among his latest innovations, two key patents stand out. The first is the **Bionic Artificial Hip Joint**, which features a unique femoral stem that supports the artificial hip joint. This design includes a convex force-bearing part that connects with the greater trochanter, effectively bearing longitudinal stress. The hollow structure of the stem facilitates bone grafting, promoting integration between the prosthesis and the patient's bone. This invention retains the hard cortex surrounding the greater trochanter, enhancing the stability of the connection between the artificial joint and the femur.

The second major patent is the **Bionic Artificial Interphalangeal Joint**. This innovative joint consists of three pairs of prostheses specifically designed for the joints extending from the metacarpal bone to the distal phalanx. With the capability to mimic natural finger movement, this joint allows for multiple degrees of freedom. The proximal phalanx can bend in various directions, achieving an impressive bending angle of about 90 degrees toward the inner side of the finger.
