Retinaculatome and a method of transecting a flexor retinaculum in a carpal tunnel release surgery using the retinaculatome

A method of transecting a flexor retinaculum in a carpal tunnel release surgery using a retinaculatome, the method comprising:

• inserting a borescope into a sleeve interior cavity of a sterile borescope sleeve of the retinaculatome, the sterile borescope sleeve comprising a sleeve exterior shell that is sealed along its length and sealed at a sleeve distal end, wherein the sleeve distal end has an incision imaging window transparent to the sleeve interior cavity;
• positioning a surgical blade in a mounted blade position defined by a surgical blade mount connected to a lower guide plate extending from the sleeve distal end, the mounted blade position overlying the lower guide plate;
• positioning the retinaculatome within a surgical incision such that the lower guide plate defines a horizontal surgical travel direction;
• and
• transecting the flexor retinaculum by advancing the surgical blade along the horizontal surgical travel direction while viewing through the incision imaging window using the borescope.
