I wish to express my sincere gratitude and regards to my project guide,
Prof. C. D. Dokal. His guidance and support throughout the program has been
a major factor in the successful completion of the present work. This work
would not have culminated into the present form without his invaluable
suggestions and generous help.
I am especially thankful to Dr. C.M. Patel (manager at Rajkot branch,
Endolite India.) for providing their valuable suggestion for the project.
I am thankful to all faculties and friends at Government Engineering
College, Bhavnagar who not only provided valuable suggestions and constant
help during my work but also made my stay at the college an enjoyable
Above all, I am forever thankful to my parents & sister for their love and
GAUTAM M. DOBARIYA
It is mechanical elbow unit operated by cable. All body powered elbow operated by
cable system. It is opened by shoulder depression, shoulder abduction and extension.
There are approximately 5000–10,000 major upper limb amputations per year, and
they are most commonly caused by trauma. The most common group is males aged 15–
50 years. In the younger age group of 1–15 years old, congenital deficiency and cancers
can also lead to upper limb amputation. The distribution of amputation is generally twothirds below the level of the elbow and one-third above.
The Mechanical Locking Elbow is a cable-operated elbow system with an
alternating lock. The system is designed for rapid assembly, and the socket can be
attached by either laminated or riveted construction.
It is very simple to maintain and operate.
A prosthetic elbow for an amputee. First and second connector parts are adapted to be
connected to an artificial upper arm and an artificial lower arm, respectively, for the
amputee.The system mechanical efficiency is a key factor of the whole project.
A lock is used for selectively stopping the rotation...
