Parallel handle system and method for designing a parallel handle system

Abstract

A parallel handle, parallel handle system and method for designing parallel handles for a hand for use with tools or control mechanisms, that includes a handle having a radial section having a side for receiving the thumb and having a side for receiving the index finger, the radial section having a surface for engaging a portion of the palmar surface of the hand, a middle section having a side for receiving at least a portion of the middle finger and at least a portion of the ring finger and having a surface that avoids placing undue pressure on a surface of the hand located over the carpal tunnel, and an ulnar section having a side for receiving the small finger and having a surface for engaging a portion of the palmar surface of the hand so as to position the end of the small finger.

AI Technical Summary

Benefits of technology

"The present invention is about a new type of handle system for a hand that can be used for various tools and devices. The handle system has three parallel members that fit comfortably on the hand and do not put pressure on the carpal tunnel. The handle system can be attached to various surgical instruments, pliers, and other tools. The handle system has a radial section for the thumb and index finger, a middle section for the middle finger, ring finger, and small finger, and an ulnar section for the small finger. The handle system is designed to avoid undue pressure on the carpal tunnel and can be easily adjusted for different hand sizes. The technical effects of this invention are improved comfort, improved grip, and reduced risk of injury from using tools and devices."

Problems solved by technology

Discomfort and hand fatigue occurs with repetitive use of handles for tools with hinges based on the lever system.

However, the repetitive use of such tools can result in disability for workers.

The pressure produced in that area of the palm can cause discomfort and pain.

Also such pressure on the TCL can limit the effectiveness and accuracy of a in the measurement of grip strength, such as when the wrist is injured.

However, tools generally based on a triangular levered system typically may not comfortable.
