Abstract:

A surgical retractor assembly is disclosed that includes a bone plate and a retractor. The bone plate has a tapered end portion. The retractor includes a base having (i) a body defining a bottom surface and a distal portion, the distal portion defining a distal surface, (iii) a first pair of tabs extending from the body that are spaced apart from each other, and (iv) a second pair of tabs extending from the body that are spaced apart from each other. The retractor further includes a handle attached to the base. The first pair of tabs and the bottom surface define a first plate space. The second pair of tabs and the distal surface define a second plate space.

International Classification:

A61F 5/00

US Classification:

606 87, 606 79, 606 96

Abstract:

A bone cutting assembly includes a guide pin that may be securely inserted into a bone to define a cutting axis. The bone cutting assembly also includes a housing having a cam surface and features for temporarily fastening the housing to the bone. The bone cutting assembly also includes a burr mounting arm that rotatably and slidably fits onto the guide pin so that the arm can swing around the cutting axis and also translate up and down the guide pin. A user may move the burr mounting arm about the cutting axis so that the arm follows along the cam surface of the housing.

US Classification:

623 1911

Abstract:

A shoulder prosthesis includes a vault-filling component defining a bearing-facing surface and having a first coupling component, the vault-filling component including (i) a vault-filling first portion defining a first part of the bearing-facing surface, and (ii) a projecting second portion projecting from the vault-filling first portion so as to define a second part of the bearing-facing surface. The vault-filling first portion and the projecting second portion define a bone space therebetween. The shoulder prosthesis further includes a bearing component defining a bearing surface and having a second coupling component configured to cooperate with the first coupling component to couple the bearing component to the vault-filling component. At least one bone attachment member positioned in the bone space. The projecting second portion of the vault-filling component further defines a scapula-facing surface.

Abstract:

A bone cutting assembly. The bone cutting assembly includes a guide pin having a distal tip that may be securely inserted into a bone to define a cutting axis and a housing having a cam surface and features which allow the housing to be temporarily secured to the bone. The bone cutting assembly further includes a burr mounting arm which can be fitted on to the guide pin so that it can swing around the cutting axis and also translate up and down the guide pin. The burr mounting arm is configured to act against the cam surface as it is swung around the guide pin, so that the arm is caused to move up or down relative to the guide pin by the action of the cam surface.
