Abstract

A limb holder generally includes a limb holder assembly, a sled or yoke assembly, a pylon and support bar assembly, a clamp assembly, and a retractor assembly. A limb, such as a leg, is supported by the limb holder. The limb holder is supported by a sled which can move along a support bar that is supported by virtue of a mounting pylon. The mounting pylon is fixed in place by a clamp assembly, the clamp assembly being attached directly to a bed, table, or other patient support. The limb holder can also receive one or more retractor assemblies capable of retracting an incision, such that a user may manipulate a patient's limb during a procedure in which the use of retractors is desired.

First claim

The invention claimed is:

1. A limb positioning device comprising:
a clamp attachable to a patient support;
a first support member configured to connect to the clamp;
a second support member slidingly coupled to the first support member;
a limb holder polyaxially and detachably coupled to the second support member; and
a support wing attached to and extending from the limb holder, the support wing having a retractor attachment portion including a plurality of discrete, spaced apart attachment features disposed thereon and positioned on both a medial and lateral side of the limb holder for coupling a retractor to the support wing, the retractor being configured to hold an incision open.

2. The limb positioning device of claim 1 , further comprising a tracking system for use with a navigation system, wherein a component of the tracking system is mountable to the support wing.

3. The limb positioning device of claim 1 , wherein the first support member further comprises:
a post connected to the clamp; and
an elongate bar providing a track along which the second support member can slide.

4. The limb positioning device of claim 3 , wherein the second support member includes a ball and socket assembly.

5. The limb positioning device of claim 4 , wherein the second support member includes a second lock configured to be in one of a locked state in which the ball is capable of zero degrees of movement with respect to the second support member and an unlocked state in which the ball is capable of at least two degrees of movement with respect to the second support member.

6. The limb positioning device of claim 4 , wherein the ball is configured to attach the limb holder to the second support member.

7. The limb positioning device of claim 6 , wherein the limb holder is capable of three degrees of freedom of movement with respect to the second support member.

8. The limb positioning device of claim 3 , wherein the second support member includes a first lock biased by at least one spring to a locked state with respect to the elongate bar in which the second support member cannot slide along the elongate bar.

9. The limb positioning device of claim 8 , wherein, upon application of force, the first lock is configured to change from the locked state to an unlocked state with respect to the elongate bar in which the second support member can slide along the elongate bar.

10. The limb positioning device of claim 3 , wherein the elongate bar comprises a first portion and a second portion, one of the first portion and second portion configured to be coupled to the post, and the first portion configured to be coupled to the second portion.

11. The limb positioning device of claim 10 , wherein the elongate bar further includes a coupling mechanism, the coupling mechanism comprising a protrusion on one end of the first portion and a slot in one end of the second portion, the slot configured to accept the protrusion.

12. The limb positioning device of claim 1 , wherein the limb holder is infinitesimally adjustable in six degrees of movement with respect to the clamp.

13. The limb positioning device of claim 1 , further comprising a retractor coupled to the support wing, the retractor configured to hold an incision open.

14. The limb positioning device of claim 1 , wherein at least a portion of the support wing is at least partially circular with a virtual center configured to align with a center of a joint of a limb positioned in the limb holder.

15. A limb positioning assembly comprising;
a clamp;
a support post connectable to the clamp and infinitesimally adjustable in at least one degree of movement with respect to the clamp;
a rail connectable to the support post;
a support assembly connectable to the rail and infinitesimally adjustable with respect to the rail in at least one degree of movement;
a limb holder detachably connectable to the support assembly and infinitesimally adjustable with respect to the support assembly in at least three degrees of movement; and
a support wing attached to and extending from the limb holder, the support wing having a retractor attachment portion including a plurality of discrete, spaced apart attachment features disposed thereon and positioned on at least one of a medial and lateral side of the limb holder for coupling a retractor to the support wing, the retractor being configured to hold an incision open.
