Radially expanding surgical retractor
View Patent ↗A radially expanding surgical retractor which includes a base having a thickness, the base having a first slot extending through the thickness in a first arc, and a second slot discrete from the first slot and extending through the thickness in a second arc. The radially expanding surgical retractor further includes a first handle, a second handle, a first blade extending through the first slot and connected to the first handle, and a second blade extending through the second slot and connected to the second handle.
1. A radially expanding surgical retractor, comprising:
a base having a thickness, said base including a first slot extending through said thickness in a first arc, and a second slot discrete from said first slot and extending through said thickness in a second arc, said first slot having two sides with curved facing surfaces defined by said first arc;
a first handle;
a second handle;
a first blade extending through said first slot and connected to said first handle; and
a second blade extending through said second slot and connected to said second handle.
2. The radially expanding surgical retractor of claim 1 , further including a third blade fixedly connected to said base.
3. The radially expanding surgical retractor of claim 1 , wherein said first arc has a first radius, said second arc has a second radius, said second radius less than said first radius.
4. The radially expanding surgical retractor of claim 3 , wherein at least one of said first blade is slidable within said first slot and said second blade is slidable within said second slot.
5. The radially expanding surgical retractor of claim 1 , further including a bale rotatably connected to one of said first handle and said second handle.
6. The radially expanding surgical retractor of claim 5 , wherein an other of said first handle and said second handle includes a catch for said bale.
7. The radially expanding surgical retractor of claim 1 , wherein at least one of said first blade and said second blade has a flange extending outwardly relative to said base.
8. The radially expanding surgical retractor of claim 1 , wherein at least one of said first blade and said second blade extends outwardly relative to said base.
9. A radially expanding surgical retractor, comprising:
a base having a thickness, said base including a first slot extending through said thickness in a first arc, and a second slot discrete from said first slot and extending through said thickness in a second arc;
a first handle;
a second handle;
a first blade extending through said first slot and connected to said first handle; and
a second blade extending through said second slot and connected to said second handle; and
a bale rotatably connected to one of said first handle and said second handle, an other of said first handle and said second handle includes a catch for said bale, said catch is an indent in said other of said first handle and said second handle.
10. A radially expanding surgical retractor, comprising:
a base having a thickness, said base including a first slot extending through said thickness in a first arc, and a second slot discrete from said first slot and extending through said thickness in a second arc;
a first handle;
a second handle;
a first blade extending through said first slot and connected to said first handle;
a second blade extending through said second slot and connected to said second handle, at least one of said first blade and said second blade are rotatable to an open position where said first blade is opposed to said second blade, further including a bale captive at one of said first handle and said second handle which connects to a catch at an other of said first handle and said second handle when said radially expanding surgical retractor is in said open position.
11. A method of using a radially expanding surgical retractor, comprising the steps of:
providing a base having a thickness, said base including a first slot extending through said thickness in a first arc, said base including a second slot discrete from said first slot and extending through said thickness in a second arc, a first handle, a second handle, a first blade extending through said first slot and connected to said first handle, a second blade extending through said second slot and connected to said second handle and a bale rotatably mounted to one of said first handle and said second handle;
inserting said first blade and said second blade into a surgical incision;
rotating at least one of said first handle and said second handle into a near vicinity of an other of said first handle and said second handle, thereby positioning said first blade and said second blade in an opposed relationship and retracting said incision; and
locking said first blade and said second blade in said opposed relationship by pivoting said bale so that said bale is inserted into a catch on an other of said first handle and said second handle.
12. A radially expanding surgical retractor, comprising:
a base having a thickness, said base including a first slot extending through said thickness in a first arc, and a second slot discrete from said first slot and extending through said thickness in a second arc, said first slot having two sides defined by said first arc;
a first handle;
a second handle;
a first blade extending through said first slot and connected to said first handle; and
a second blade extending through said second slot and connected to said second handle, said first arc having a first radius, said second arc having a second radius, said second radius being less than said first radius, said first blade having an arced surface that corresponds to said first arc, said first blade being configured to move in a curved direction defined by said first arc.
