Surgical retractor assembly and associated method of use
View Patent ↗A surgical retractor assembly is disclosed that includes a bone plate and a retractor. The bone plate has a tapered end portion. The retractor includes a base having (i) a body defining a bottom surface and a distal portion, the distal portion defining a distal surface, (iii) a first pair of tabs extending from the body that are spaced apart from each other, and (iv) a second pair of tabs extending from the body that are spaced apart from each other. The retractor further includes a handle attached to the base. The first pair of tabs and the bottom surface define a first plate space. The second pair of tabs and the distal surface define a second plate space.
1. A surgical retractor assembly, comprising:
a bone plate having a tapered end portion; and
a retractor including:
a base having (i) a body defining a bottom surface and a distal portion, said distal portion defining a distal surface, (iii) a first pair of tabs extending from said body that are spaced apart from each other, and (iv) a second pair of tabs extending from said body that are spaced apart from each other, and
a handle attached to said base,
wherein said first pair of tabs and said bottom surface define a first plate space,
wherein said second pair of tabs and said distal surface define a second plate space,
wherein said retractor is positionable in relation to said bone plate between a first position and a second position,
wherein, when said retractor is positioned in said first position, (i) said bone plate is positioned in said first plate space, and (ii) said bone plate is located outside of said second plate space,
wherein, when said retractor is positioned in said second position, (i) said bone plate is positioned in said second plate space, and (ii) said bone plate is located outside of said first plate space,
wherein:
said first pair of tabs includes a first tab and a second tab,
at least a portion of said first tab extends downwardly in relation to said bottom surface of said body of said base of said retractor, and
at least a portion of said second tab extends downwardly in relation to said bottom surface of said body of said base of said retractor, and
wherein:
said first tab includes a first L-shaped member that has (i) a first connecting portion extending from a first lateral side surface of said body of said base of said retractor, and (ii) a first guide portion attached to said first connecting portion, and
said second tab includes a second L-shaped member that has (i) a second connecting portion extending from a second lateral side surface of said body of said base of said retractor, and (ii) a second guide portion attached to said second connecting portion.
2. The assembly of claim 1 , wherein:
said base further has a proximal portion, and
said handle is attached to said proximal portion.
3. The assembly of claim 1 , wherein:
said bone plate defines a bone contact side and an opposite side, and
said retractor is positioned in contact with said opposite side of said bone plate when said bone plate is positioned in said first plate space.
4. The assembly of claim 3 , wherein:
said tapered end portion of said bone plate defines a first side wall portion and a second side wall portion, and
said retractor is positioned in contact with said first side wall portion and said second side wall portion when said bone plate is positioned in said second plate space.
5. The assembly of claim 1 , wherein:
said second pair of tabs includes a third tab and a fourth tab, and
each of said third tab and said fourth tab extends distally from said body of said base of said retractor.
6. The assembly of claim 1 , wherein:
said bottom surface of said body of said base of said retractor defines a first plane,
said handle defines a second plane,
said first plane and said second plane intersect to define an angle Θ, and 130°<Θ<150°.
7. A surgical retractor, comprising:
a base having (i) a body defining a bottom surface and a distal portion, said distal portion defining a distal surface, (iii) a first pair of tabs extending from said body that are spaced apart from each other, and (iv) a second pair of tabs extending from said body that are spaced apart from each other, and
a handle attached to said base,
wherein said first pair of tabs and said bottom surface define a first plate space configured to receive a first portion of a bone plate therein,
wherein said second pair of tabs and said distal surface define a second plate space configured to receive a second portion of the bone plate therein,
wherein:
said first pair of tabs includes a first tab and a second tab,
at least a first portion of said first tab extends downwardly in relation to said bottom surface of said body of said base, and
at least a second portion of said second tab extends downwardly in relation to said bottom surface of said body of said base, and
wherein:
said first tab includes a first L-shaped member that has (i) a first connecting portion extending from a first lateral side surface of said body of said base, and (ii) a first guide portion attached to said first connecting portion, and
said second tab includes a second L-shaped member that has (i) a second connecting portion extending from a second lateral side surface of said body of said base of said retractor, and (ii) a second guide portion attached to said second connecting portion.
8. The assembly of claim 7 , wherein:
said base further has a proximal portion, and
said handle is attached to said proximal portion.
9. The assembly of claim 7 , wherein:
said second pair of tabs includes a third tab and a fourth tab, and
each of said third tab and said fourth tab extends distally from said body of said base.
10. The assembly of claim 7 , wherein:
said bottom surface of said body of said base defines a first plane,
said handle defines a second plane,
said first plane and said second plane intersect to define an angle Θ, and 130°<Θ<150°.
