Abstract
The self-retaining nasal septum retractor includes two pivotally attached arms having handles on one end and speculum blades on the opposing end. The speculum blades are adjustably connected to the arms through pivoting joints. A user can adjust the vertical displacement and angular relation between the speculum blades and the arms to fit different patient septal/nasal structures. A self-retaining mechanism allows a user to lock the retractor in a retracted position, freeing up a hand of the user for other surgical tasks.
Claims8
A self-retaining nasal septum retractor, comprising:
- a first arm and a second arm, each of the arms having a proximal portion, a distal portion, and an intermediate portion between the proximal portion and the distal portion;
- an arm joint pivotally connecting the first and second arms at their intermediate portions;
- a first intermediate member and a second intermediate member;
- a first nasal speculum blade and a second nasal speculum blade, each of the speculum blades consisting of an elongated blade portion and an integral connecting portion disposed perpendicular to the elongated blade portion;
- a first proximal speculum joint pivotally connecting the first intermediate member to the distal portion of the first arm and a second proximal speculum joint pivotally connecting the second intermediate member to the distal portion of the second arm, the first and second proximal speculum joints being independently adjustable, wherein the independent adjustability is a user-adjustable pivoting stiffness;
- a first distal speculum joint pivotally connecting the first nasal speculum blade connecting portion directly to the first intermediate member and a second distal speculum joint pivotally connecting the second nasal speculum blade connecting portion directly to the second intermediate member, the first and second distal speculum joints being independently adjustable, wherein the independent adjustability is a user-adjustable pivoting stiffness;
- and
- a self-retaining mechanism attached to the first arm and the second arm, the self-retaining mechanism selectively locking the first and second arms with the first and second nasal speculum blades at a user-selectable angular separation.
