Retractor and methods of use
View Patent ↗A retractor is disclosed. The retractor includes a housing, at least one blade holder slidably coupled to the housing, and an actuator handle to control sliding movement of the blade holder. The blade holder and the actuator handle hold at least one blade.
1. A retractor, comprising:
a housing;
a plurality of blade holders comprising a first blade holder, a second blade holder, and a third blade holder, wherein said blade holders are radially disposed within said housing and configured to be slidably coupled to said housing; and
an actuator handle coupled to a spool mechanism comprising a first cable system having at least one cable configured to control movement of said first blade holder, a second cable system having at least one cable to control translational movement of said second blade holder, and a third cable system having at least one cable configured to control translational movement of said third blade holder; wherein
said at least one blade holder is configured to hold at least one blade;
said at least one blade holder includes a blade holder tip configured to allow exchange of said at least one blade with another blade;
said at least one blade holder and blade holder tip are interchangeable.
2. The retractor according to claim 1 , wherein said spool mechanism is configured to be controlled by said actuator handle.
3. The retractor according to claim 1 , wherein at least one of said cable systems are configured to be controlled by said actuator handle.
4. The retractor according to claim 1 , wherein said actuator handle is configured to control tension of one or more cables of said cable system upon the compression of said actuator causing said blade holders to retract away from a center of said housing.
5. The retractor according to claim 1 , wherein said blade holders are configured to be at least partially disposed within said hollow center portion and are further configured to radially translate within said hollow center portion.
6. The retractor according to claim 1 , further comprising a plurality of blades, each for a respective blade holder, said blades are configured to move with said blade holders and configured to spread body tissue within a body of a patient apart upon actuation of the actuation holder.
7. The retractor according to claim 1 , wherein said blade holders are configured to uniformly move in unison within said housing.
8. A method for retracting body tissue within a body of a patient using a retractor device having
a housing with a hollow center portion,
a plurality of radially spaced apart blade holders having corresponding blades, wherein the blade holders are configured to slidably coupled to the housing,
an actuator handle, coupled to a spool mechanism having at least one cable coupled to the at least one blade holder, and configured to control translational movement of the blade holders within hollow center portion of the housing, wherein each blade holder is configured to hold a blade and the at least one blade holder includes a blade holder tip configured to allow exchange of the at least one blade with another blade; wherein the at least one blade holder and blade holder tip are interchangeable,
the method comprising the steps of:
releasing the actuator handle, wherein said releasing translates the blade holders towards a center of the hollow center portion of the housing and forces the blades together;
inserting the pushed-together blades into the body tissue selected for retraction;
compressing the actuator handle, wherein said compression translates the blade holders away from the center of the hollow center portion of the housing and radially translates the blades apart resulting in the blades being spread apart from the center of the hollow center portion of the housing spreading of body tissue apart.
9. The method according to claim 8 , wherein said releasing further comprises lessening tension in the at least one cable and causing the blade holders to move toward the center of the center portion of the housing.
10. The method according to claim 8 , wherein said tensioning further comprises increasing tension in the at least one cable and causing the blade holders to retract away from the center of the center portion of the housing.
11. The method according to claim 8 , wherein the blade holders are configured to be at least partially disposed within the hollow center portion of the housing and are further configured to radially translate within the hollow center portion.
12. The method according to claim 8 , further comprising uniformly moving the blade holders in unison within the housing.
13. The method according to claim 8 , further comprising non-uniformly moving the blade holders within the housing.
