Abstract

A surgical retractor includes a first member defining a longitudinal axis. The first member includes a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface. A second member has a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface. The grip surfaces are configured to be drawn together along the longitudinal axis such that the blades are engageable with tissue and connected with the grip surfaces such that the grip surfaces provide a tactile feedback of the tissue engagement. Systems and methods of use are disclosed.

First claim

What is claimed is:

1. A surgical retractor comprising:
a first member defining a longitudinal axis and including a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface, the blade being coupled to a first arm of the first member; and
a second member including a blade disposed in spaced apart relation relative to the longitudinal axis, a housing and a grip surface comprising a plurality of holes each extending parallel to the longitudinal axis, the first member extending through the grip surface of the second member and the housing, the second member including a second arm comprising a shaft that is fixed to the housing and a tubular portion that is rotatable relative to the shaft, the blade of the second member being coupled to the tubular portion such that the blade of the second member is rotatable relative to the shaft about an axis defined by the shaft, the housing having an outer surface and an opposite inner surface defining a cavity, the cavity having the first member positioned therein, the grip surface of the second member being fixed to the housing, the grip surface of the second member including a first portion, a second portion and a gap between the first portion and the second portion, the housing including a lock configured to engage an engagement surface of the first member, a portion of the lock being positioned in the gap, the first and second portions each extending laterally from the outer surface in opposite directions, the grip surface of the second member having a maximum width along a transverse axis that extends parallel to the shaft, the maximum width of the grip surface of the second member being greater than a maximum width of the housing along the transverse axis, wherein the grip surfaces are offset from the arms and are movable between a first orientation in which the grip surfaces directly engage one another such that the blades are engageable with tissue and the grip surfaces are configured to provide a tactile feedback of the tissue engagement and a second orientation in which the grip surfaces are spaced apart from one another, and
wherein the retractor is configured to be operated manually and is free of any electrical components and is not in communication with any electrical components.

2. A surgical retractor as recited in claim 1 , wherein the grip surfaces each extend laterally from a respective one of the members and transverse to the longitudinal axis.

3. A surgical retractor as recited in claim 1 , wherein the housing is tubular.

4. A surgical retractor as recited in claim 3 , wherein the first portion is configured for engagement with a first finger and the second portion is configured for engagement with a second finger.

5. A surgical retractor as recited in claim 1 , wherein the grip surface of the first member is configured for engagement with a first finger and the grip surface of the second member is configured for engagement with a second finger and a third finger such that the fingers draw the grip surfaces together to move the first member in a first axial direction and the second member in a second axial direction that is opposite to the first axial direction.

6. A surgical retractor as recited in claim 1 , wherein the grip surfaces are drawn together to move the first member in a first axial direction and the second member in a second axial direction that is opposite to the first axial direction.

7. A surgical retractor as recited in claim 1 , wherein the grip surfaces are configured to be drawn together by compressing the grip surfaces.

8. A surgical retractor as recited in claim 1 , wherein the lock is configured to engage the engagement surface to selectively space the blades apart.

9. A surgical retractor as recited in claim 1 , wherein the blade of the first member extends from an outer surface of the first member along a first axis transverse to the longitudinal axis and is rotatable about the first axis, the first axis extending parallel to the transverse axis.

10. A surgical retractor as recited in claim 9 , wherein the blade of the first member is rotatable relative to the first arm.

11. A surgical retractor as recited in claim 10 , wherein the blade of the first member is configured for indexed rotation relative to the first arm in angular increments.

12. A surgical retractor as recited in claim 9 , wherein the blade of the second member extends along the transverse axis and is spaced apart from the first axis, the blade of the second member being rotatable about the transverse axis.

13. A surgical retractor as recited in claim 1 , wherein:
the first member comprises an engagement surface;
the lock is configured to engage the engagement surface to selectively space the blades apart, the lock being pivotable about a pivot axis that extends parallel to the arms;
the engagement surface comprises a plurality of teeth and the lock comprises a latch that is releasably engageable with the first member to selectively distract the blades in a fixed orientation, the latch comprising a lever having a first end with a knurled surface and a second end having a protrusion configured to engage the teeth; and the first end of the lever is the portion of the lock positioned in the gap.

14. A surgical retractor as recited in claim 13 , wherein the lever is engageable for pivotable movement between a non-locking configuration such that the protrusion is released from engagement with the teeth and the first member is freely slidable relative to the second member to selectively position the blades, and a locking configuration such that the lever is released from manipulative engagement such that the protrusion engages the teeth and the first member is fixed relative to the second member, the latch comprising a spring that resiliently biases the lever to the locked configuration.

15. A surgical retractor as recited in claim 1 , wherein the first arm is coaxial with the transverse axis, the first arm comprising an outer surface with a plurality of splines, wherein the blade of the first member comprises an inner surface with a plurality of splines that mate with the splines of the first arm to align and mount the blade of the first member with the first arm.

16. A surgical retractor as recited in claim 1 , wherein the blades each include a plurality of feet that extend outwardly from outer surfaces of the blades and are configured to distract tissue as the blades move away from one another.

17. A surgical retractor as recited in claim 1 , wherein the housing is positioned between the grip surface of the first member and the arm of the first member.

18. A surgical retractor comprising:
a first member including a shank defining a longitudinal axis, the first member including a first blade disposed in spaced apart relation relative to the longitudinal axis and a first grip surface, the first blade being coupled to a first arm of the first member; and
a second member including a second blade disposed in spaced apart relation relative to the longitudinal axis, a housing and a second grip surface comprising a plurality of holes each extending parallel to the longitudinal axis, at least one of the holes being encircled by the second grip surface, the shank extending through the second grip surface and the housing, the second member including a second arm comprising a shaft that is fixed to the housing and a tubular portion that is rotatable relative to the shaft, the second blade being coupled to the tubular portion such that the second blade is rotatable relative to the shaft about an axis defin
