Abstract

Devices and methods for positioning a patient's leg during a leg or knee operation by employing a novel surgical leg positioning device. The device has a low profile so that it can remain under sterile surgical drapes during an operation, and prevents the leg from moving out or up. Large, easy to access, buttons are provided to allow the surgical leg positioning device to be manipulated while under sterile surgical drapes so that it may be moved when no longer needed.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1 . A surgical leg positioning device for stabilizing a leg during surgery, comprising:
a post; and a main body including a main base or plate rigidly connected to the post, a rotational positioning base supported by the main base or plate, a frame supported by the rotational positioning base and configured to slide relative to the rotational positioning base, and three actuating mechanisms that allow the main body to move in three different planes of motion without removing sterile surgical drapes around the leg during the surgery.

2 . The surgical leg positioning device of claim 1 , wherein the three actuating mechanisms include a first actuating mechanism in the form of a pull knob attached to a rail adapter to raise and lower the post attached to the main body relative to the rail adapter and in a vertical plane; a second actuating mechanism in the form of a lateral positioning button to move the frame laterally relative to the leg and in a horizontal plane; and a third actuating mechanism in the form of a rotational button to pivot or rotate the main body in a rotational plane.

3 . The surgical leg positioning device of claim 1 , wherein the frame comprises a first curved member configured to prevent the leg from shifting vertically or laterally over the post, a second curved member, and a base member.

4 . The surgical leg positioning device of claim 3 , further comprising a sterile pad affixed to the first curved member.

5 . The surgical leg positioning device of claim 4 , wherein the sterile pad is disposable and nonsterile.

6 . The surgical leg positioning device of claim 1 , further comprising a rail adapter for coupling to a rail of an operating table, the rail adapter being configured to allow the post to slide within a through hole or receiver hole in the rail adapter and to be securely locked to the rail adapter by manually tightening a knob.

7 . A method of using a surgical leg positioning device during operation, comprising the steps of:
providing a surgical leg positioning device, wherein the surgical leg positioning device comprises a rail adapter, a post, and a main body, wherein the post is received within an opening of the rail adapter, wherein the main body includes a main base or plate rigidly connected to the post, a rotational positioning base supported by the main base or plate, a frame supported by the rotational positioning base and configured to slide on a top surface of the rotational positioning base, and three actuating mechanisms that allow the main body to move in three different planes of motion without removing sterile surgical drapes around a patient's leg during surgery; positioning the surgical leg positioning device in a desired location relative to the patient's leg; draping a sterile surgical drape over the patient's leg and the surgical leg positioning device; and moving the surgical leg positioning device along three different planes of motion without removing the sterile surgical drape.

8 . The method of claim 7 , further comprising the steps of:
mounting the rail adapter to a rail attached to an operating room bed; positioning the rail adapter in a desired location and securing the rail adapter by manipulating an adapter knob; placing the post in a receiver hole of the rail adapter; adjusting the surgical leg positioning device to a desired height by manipulating a height adjustment knob of the rail adapter; adjusting a rotational position of the surgical leg positioning device by manipulating a rotational button on the main body; and adjusting a lateral position of the surgical leg positioning device by manipulating a lateral positioning button.

9 . The method of claim 7 , further comprising the step of providing a sterile foam pad on an arm of the frame.

10 . The method of claim 7 , wherein the surgery is knee arthroscopic surgery.
