Patent number: 10975592Abstract: A barrier having first and second spaced posts interconnected by a rail, wherein the rail and posts are not inserted within one another. In the exemplary embodiments, the parts are hollow in at least the region of the intended interconnection. Each post is connected to the rail by a coupling. Each coupling includes a connector that extends inside the hollow region of the post and rail. The post includes an aperture wherein when assembled the connector extends through the aperture. The connecter includes an abutment that abuts an inside of the post to prevent movement of the connector through the aperture. The connector is moveable further into one of the hollow sections of the post or rail to withdraw the connector from the other of the post or rail. This allows the rail to be disconnected from the post without increasing the distance between the two spaced posts.Type: GrantFiled: January 21, 2015Date of Patent: April 13, 2021Assignee: THREE SMITH GROUP LIMITEDInventors: Luke Smith, Dean Cowan

Patent number: 9398929Abstract: A multi-pin pin impactor and method of use are described. The pin impactor includes a body which can be held by a user and manipulated to re-position the pin impactor during use. First and second pin holders are attached to the body and each include a pin release mechanism effective to releasably retain a pin within the pin holder. An impaction can have a force applied to apply a driving force to a one of the pins. In use, a first pin held by the pin impactor is introduced into an aperture in a surgical instrument mounted on a bone. A force is applied to the pin impactor to drive the first pin into the bone. The orientation or position of the pin impactor is changed to introduce a second pin held by the pin impactor into a second aperture in the surgical instrument without re-loading the pin impactor and a force is applied to the pin impactor to drive the second pin into the bone.Type: GrantFiled: November 11, 2011Date of Patent: July 26, 2016Assignee: DEPUY (IRELAND)Inventors: Duncan Young, Dean Cowan

Patent number: 9023055Abstract: A surgical instrument for attachment to a cutting block having a cutting slot defining a cutting plane is described. The surgical instrument comprises a dual purpose indicator (2) member. The indicator member is configured to (i) allow visualization of a first plane and (ii) to indicate a predetermined distance from a second plane perpendicular to the first plane. The surgical instrument also comprises an attachment member (14,16,18,20) for attaching the surgical instrument to the cutting slot in either of two mutually perpendicular orientations such that either the first plane or the second plane is parallel to the cutting plane. The surgical instrument can therefore be used both to visualize a plane of a cut and to indicate a distance from the plane of a cut, depending on the orientation of the attachment member in the cutting slot. This allows inventory to be reduced because the surgical instrument can replace two prior art instruments.Type: GrantFiled: March 22, 2011Date of Patent: May 5, 2015Assignee: Depuy (Ireland)Inventors: Dean Cowan, Ian Leslie, Alberto Verteramo

Patent number: 9023054Abstract: A surgical resection guide comprising: a housing (36); a stylus arm (38) extending through the housing (36) arranged such that when the housing (36) is coupled to the side of a bone, a tip of the stylus arm (38) is arranged to contact an end of a bone; and a linear adjustment mechanism. The linear adjustment mechanism comprises: a shaft (30) at least partially received within a bore extending through the housing (36) such that the shaft (30) can slide along its longitudinal axis relative to the housing (36), the shaft (30) incorporating a shaft tooth or groove (50); and a dial (44) rotatably coupled to the housing (36) and incorporating a helical dial groove or rib (48) defining a longitudinal axis offset from the longitudinal axis of the shaft (30).Type: GrantFiled: April 14, 2014Date of Patent: May 5, 2015Assignee: Depuy (Ireland)Inventors: Dean Cowan, Duncan Young

Patent number: 8128705Abstract: An assembly for use in a procedure for implantation of an orthopedic joint component, comprises a head part of the joint component which has a tapered bore within it, and a connector part which is tapered inwardly along its length so that it can be received snugly in the tapered bore in the head part, the connector part having a bore within it. A tool includes a spigot which fits snugly into the bore in the connector part. Each of the tool and the connector part has a face which contact one another when the spigot on the tool is fully received in the bore in the connector part, and in which each of the said faces extends generally transverse relative to the aligned axes of the spigot and the bore.Type: GrantFiled: March 27, 2008Date of Patent: March 6, 2012Assignee: DePuy International LimitedInventors: Alec Birkbeck, Dean Cowan
