Abstract

A patient lower extremity positioning system that is configured to facilitate easier use of surgical instruments during open and arthroscopic procedures of the lower extremity, including, but not limited to the hip joint, acetabulum, femur, femoral neck and femoral shaft is disclosed. The patient lower extremity positioning system may include one or more perineal pads configured to be supported adjacent to a patient torso support such that the perineal pad is positionable adjacent to a patient's perineum. The perineal pad may be formed from a perineal pad body coupled to a distal transition section extending distally from the perineal pad body. The distal transition section may have a distal tip with a cross-sectional area that is less than a cross-sectional area of the perineal pad body, thereby enabling a surgeon to more easily position surgical instruments during surgery without the perineal pad conflicting with the surgical instruments.

First claim

We claim:

1. A patient lower extremity positioning system, comprising:
at least one perineal pad formed from a perineal pad body coupled to a distal transition section extending distally from the perineal pad body;
wherein the distal transition section has a distal tip with a cross-sectional area that is less than a cross-sectional area of the perineal pad body at an intersection of the distal transition section and the perineal pad body;
wherein the at least one perineal pad is configured to be supported adjacent to a patient torso support such that the perineal pad is positionable adjacent to a patient's perineum;
wherein the distal transition section of the at least one perineal pad is generally conical;
wherein the distal transition section has a length that is greater than about one quarter of a total length of the at least one perineal pad;
wherein the distal transition section has a length that is less than about half of a total length of the at least one perineal pad;
wherein a diameter of an outer tip of the distal transition section is less than half of a diameter of the perineal pad body; and
wherein the distal transition section is configured such that an outer surface forming the distal transition section forms a linear line extending from the perineal pad body to an outer tip of the distal transition section when viewed in cross-section from a cross-sectional cut made from the outer tip of the distal transition section to a proximal end of the perineal pad body along a longitudinal axis of the at least one perineal pad and viewed orthogonal to a longitudinal axis of the at least one perineal pad.

2. The patient lower extremity positioning system of claim 1 , further comprising a torso support system coupled to the at least one perineal pad and configured to support a torso of a patient.

3. The patient lower extremity positioning system of claim 2 , wherein the torso support system is comprised of a table to which the at least one perineal pad is attached.

4. The patient lower extremity positioning system of claim 3 , further comprising at least one leg spar attached to the table.

5. The patient lower extremity positioning system of claim 4 , wherein the at least one leg spar is releasably attached to the table.

6. The patient lower extremity positioning system of claim 4 , wherein the at least one leg spar is formed from two leg spars attached to the table.

7. The patient lower extremity positioning system of claim 2 , wherein the torso support system includes at least one attachment system configured to be attached to a table.

8. The patient lower extremity positioning system of claim 1 , further comprising a support receiving chamber extending longitudinally from a proximal end of the at least one perineal pad into the perineal pad body.

9. The patient lower extremity positioning system of claim 8 , wherein the support receiving chamber is generally cylindrical.

10. The patient lower extremity positioning system of claim 8 , wherein the support receiving chamber extends completely through the perineal pad body and the distal transition section from the distal tip to a proximal end of the perineal pad body.

11. The patient lower extremity positioning system of claim 1 , wherein the perineal pad body is generally cylindrical and wherein the cross-sectional area of the perineal pad body at an intersection of the distal transition section and the perineal pad body is generally equal to a cross-sectional area of the perineal pad body at a proximal end.

12. A patient lower extremity positioning system, comprising:
at least one perineal pad formed from a perineal pad body coupled to a distal transition section extending distally from the perineal pad body;
wherein the distal transition section has a distal tip with a cross-sectional area that is less than a cross-sectional area of the perineal pad body at an intersection of the distal transition section and the perineal pad body; and
wherein the at least one perineal pad is configured to be supported adjacent to a patient torso support such that the perineal pad is positionable adjacent to a patient's perineum;
wherein the perineal pad body is generally cylindrical and wherein the cross-sectional area of the perineal pad body at an intersection of the distal transition section and the perineal pad body is generally equal to a cross-sectional area of the perineal pad body at a proximal end;
a support receiving chamber extending longitudinally from a proximal end of the at least one perineal pad into the perineal pad body;
wherein the distal transition section of the at least one perineal pad is generally conical;
wherein the distal transition section has a length that is greater than about one quarter of a total length of the at least one perineal pad;
wherein the distal transition section has a length that is less than about half of a total length of the at least one perineal pad;
wherein a diameter of an outer tip of the distal transition section is less than half of a diameter of the perineal pad body; and
wherein the distal transition section is configured such that an outer surface forming the distal transition section forms a linear line extending from the perineal pad body to an outer tip of the distal transition section when viewed in cross-section from a cross-sectional cut made from the outer tip of the distal transition section to a proximal end of the perineal pad body along a longitudinal axis of the at least one perineal pad and viewed orthogonal to a longitudinal axis of the at least one perineal pad.

13. The patient lower extremity positioning system of claim 12 , wherein the support receiving chamber is generally cylindrical and extends completely through the perineal pad body and the distal transition section from the distal tip to a proximal end of the perineal pad body.

14. The patient lower extremity positioning system of claim 12 , further comprising a torso support system coupled to the at least one perineal pad and configured to support a torso of a patient, wherein the torso support system includes at least one attachment system configured to be attached to a table and at least one leg spar releasably attached to the table.

15. A patient lower extremity positioning system, comprising:
at least one perineal pad formed from a perineal pad body coupled to a distal transition section extending distally from the perineal pad body;
wherein the distal transition section has a distal tip with a cross-sectional area that is less than a cross-sectional area of the perineal pad body at an intersection of the distal transition section and the perineal pad body; and
wherein the at least one perineal pad is configured to be supported adjacent to a patient torso support such that the perineal pad is positionable adjacent to a patient's perineum;
wherein the perineal pad body is generally cylindrical and wherein the cross-sectional area of the perineal pad body at an intersection of the distal transition section and the perineal pad body is generally equal to a cross-sectional area of the perineal pad body at a proximal end;
wherein the distal transition section of the at least one perineal pad is generally conical;
wherein the distal transition section has a length that is less than about half of a total length of the at least one perineal pad and greater than about one quarter of a total length of the at least one perineal pad;
a support receiving chamber extending longitudinally from a proximal end of the at least one perineal pad into the perineal pad body and wherein the support receiving chamber is generally cylindrical;
