Title: Toyohiko Imakita: Innovator in Prosthetic Technology

Introduction

Toyohiko Imakita is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of prosthetic technology, holding 2 patents that showcase his innovative approach to enhancing mobility for individuals with limb loss.

Latest Patents

One of Imakita's latest patents is a prosthetic leg with a knee braking function. This advanced prosthetic limb features a flexible knee brake that can mechanically detect the load distribution on the wearer's foot. The design includes a joint upper member and a joint lower member that work together to bend the knee. The housing member contains both a knee axis and a hydraulic brake circuit. A unique link mechanism allows for small relative motion between the housing member and the base bracket, serving as a sensing point to determine whether the load is on the heel or toe. Based on this detection, the hydraulic brake circuit is controlled to enable a flexible knee braking operation.

Another significant patent is a closed position maintainable selector valve, which is used in conjunction with a knee torque device for artificial legs. This selector valve can maintain a closed position even when the operating force is removed. The valve element opens and closes based on the presence or absence of the operating force, allowing for effective control of hydraulic fluid pressure. The innovative stepped structure of the valve element enhances its functionality by maintaining the closed position for a period of time.
