The Martin vaginal retractor is a classic instrument that has been in production for decades. It is a hand-held retractor designed for use in vaginal and gynecological surgeries to retract tissues and provide better access to the surgical field.

This specific 105x27mm instrument is a standard catalog item. One catalog explicitly lists the "Martin retractor" as having a 25cm length and the specific blade dimensions of 105x27mm. A historical example of a "Schiedenhatter, nach martin" (vaginal retractor, by Martin) at Wright State University also has similar dimensions (2.7 cm wide x 12 cm long), confirming the long-standing nature of this design.
