Abstract

This disclosure relates to surgical devices and methods. The disclosed surgical device and method may be used to resect, cut or otherwise remove tissue during an orthopaedic procedure. The surgical device may be reconfigured to reduce a size of the surgical device during placement in the patient.

First claim

What is claimed is:

1. A surgical guide for an orthopaedic procedure comprising:
a shield including first and second shield portions; and
a housing including a first housing portion pivotably coupled to a second housing portion; and
wherein the first and second shield portions are coupled to the respective first and second housing portions, the first and second shield portions are moveable relative to each other between a folded position and a deployed position in response to relative rotation between the first and second housing portions about an axis, the first and second shield portions are configured to bound a work area in the deployed position, the work area is dimensioned to receive a portion of bone, and the housing includes a resection slot extending from the work area.

2. The surgical guide as recited in claim 1 , wherein the first shield portion is pivotably coupled to the second shield portion at a connection, and the connection is spaced apart from the housing.

3. The surgical guide as recited in claim 2 , wherein the first and second shield portions cooperate with the housing to encircle the work area in the deployed position.

4. The surgical guide as recited in claim 1 , further comprising:
a handle releasably secured to the housing along an interface; and/or
wherein the resection slot extends between the interface and the work area.

5. The surgical guide as recited in claim 1 , wherein the first housing portion includes a first flange extending from a first body, the second housing portion includes a second flange extending from a second body, and the first and second flanges are coupled to the respective first and second shield portions.

6. The surgical guide as recited in claim 5 , wherein the first body includes a passageway extending along the resection slot, and the second body includes a pair of lock members configured to deflect inwardly in response to being inserted in the passageway and then to deflect outwardly to lock the second body in the first body.

7. The surgical guide as recited in claim 6 , further comprising:
a handle releasably secured to the housing along an interface; and
wherein the handle includes an actuation member moveable between first and second positions relative to the interface, the actuation member is configured to engage the lock members in the first position to lock the handle to the housing and is configured to disengage the lock members in the second position such that the handle is releasable from the housing.

8. The surgical guide as recited in claim 1 , wherein a first slot extends through the first housing portion, a second slot extends through the second housing portion, and the first and second slots are substantially aligned in the deployed position to establish the resection slot; and/or
wherein the resection slot is established along the axis.

9. The surgical guide as recited in claim 8 , wherein the first slot is transverse to the second slot in response to moving the shield between the deployed position and the folded position.

10. The surgical guide as recited in claim 1 , wherein the shield is flexible such that the first and second shield portions are conformable to a periphery of a portion of bone captured in the work area.

11. A kit for an orthopaedic procedure comprising:
a cutting instrument including cutting teeth; and
a surgical guide comprising:
a shield configured to bound a work area in a deployed position, the work area dimensioned to receive a portion of bone; and
a housing including first and second housing portions coupled to respective end portions of the shield;
wherein the first and second housing portions are pivotable relative to each other about an axis to move the shield between a folded position and the deployed position; and
wherein the housing includes a resection slot extending along a reference plane that intersects the work area, and the shield is configured to block movement of the cutting instrument along the reference plane.

12. The kit as recited in claim 11 , wherein the shield includes a first shield portion pivotably coupled to a second shield portion at a connection, and the connection is spaced apart from the housing.

13. The kit as recited in claim 11 , wherein a first slot extends through the first housing portion, a second slot extends through the second housing portion, and the first and second slots are substantially aligned along the reference plane in the deployed position to establish the resection slot.

14. The kit as recited in claim 11 , further comprising:
a handle releasably secured to the first housing portion along an interface; and
wherein the handle includes an actuation member moveable between first and second positions relative to the interface, the actuation member is configured to engage the second housing portion in the first position to lock the handle to the housing to block access to an entrance to the resection slot, and the actuation member is configured to disengage the second housing portion in the second position such that the handle is releasable from the first housing portion to provide access to the entrance to the resection slot.

15. A method of performing an orthopaedic procedure comprising:
situating a surgical guide at a surgical site;
moving the surgical guide from a folded position to a deployed position at the surgical site, wherein the surgical guide comprises:
a shield configured to bound a work area in the deployed position; and
a housing including first and second housing portions coupled to respective end portions of the shield;
wherein the second housing portion is pivotable relative to an axis of the first housing portion to move the shield between the folded position and the deployed position; and
wherein the housing includes a resection slot extending from the work area;

positioning a bone in the work area such that the shield at least partially surrounds a periphery of the bone; and
inserting a cutting instrument through the resection slot and into the work area to resect the bone.

16. The method as recited in claim 15 , wherein the step of positioning the bone in the work area occurs such that the shield and the housing cooperate to substantially surround the periphery of the bone.

17. The method as recited in claim 15 , wherein the surgical guide includes a handle releasably secured to the first housing portion along an interface, and an entrance to the resection slot is established along the interface, and further comprising:
moving an actuation member to unlock the handle from the second housing portion, and then moving the handle along the interface to detach the handle from the housing; and
wherein the step of inserting the cutting instrument includes moving the cutting instrument through the entrance of the resection slot subsequent to detaching the handle.

18. The method as recited in claim 17 , further comprising:
inserting an alignment rod into an aperture of the handle; and
moving the surgical guide along the periphery of the bone to adjust an angle between the alignment rod and an axis of the bone, and then inserting one or more fastening elements through the housing and then into the bone to secure the surgical guide.

19. The method as recited in claim 15 , wherein the resection slot is established along the axis; and/or
wherein the bone is a humeral head of a humerus.

20. The method as recited in claim 15 , further comprising:
moving the surgical guide in the folded position through a soft tissue passage prior to
