Kemis® is an instrument combining both the safety of the open release procedure and the clinical advantages of endoscopic surgery.


An ergonomically enhanced instrument  

Ergonomic design, upper (1) and lower (2) curves designed for reducing the risk of injury of the anatomical structures when inserting the knife. 

The blade is an integral part of the knife design (3) and does not damage surrounding tissues. 

Secured cutting of the ligament reducing the risks of median nerve and flexor tendons injury. 

Palmar aponeurosis preserved. 


A safer technique 

Immediate visualization of the ligament and distal division of the median nerve (thenar branch, digital nerves). 

Visual monitoring of the anatomic variations of the thenar eminence. 

The cutting edge of the blade (0,3mm thick) is never in contact with the surrounding anatomical structures, thus avoiding unintentional injury.
