Patent number: 10660658Abstract: The invention provides a surgical tool driver having a proximal end having a coupling and a distal end comprising a surgical tool connector having a release sleeve for disconnecting the surgical tool. The surgical tool connector further includes a locking member having a locking head adapted for coupling with at least one surgical tool. The locking member is slidingly disposed and at least substantially enclosed within the center of the driver and closely interfaces therewith so as to minimize seams, gaps or openings. The locking member has an axial range of motion which assures that between an unlock and lock position, the locking head is embedded in the driver in the unlock position and then extends axially outwardly, in snug juxtaposition with the driver, to a lock position which is capable of locking a surgical tool to the tool driver in a manner so as to avoid the exposure of a significant seam, gap or opening during activation and so helping prevent debris and/or bone chips from entering the driver.Type: GrantFiled: November 18, 2016Date of Patent: May 26, 2020Assignee: Incipio Devices SAInventors: Fabrice Chenaux, André Lechot

Patent number: 8679124Abstract: A disposable reamer is provided, made up of a base and a thin-walled, perforated cutting body of flat metal stock affixed thereto. The base and body may be molded together or assembled together in a mechanical manner. The body is optionally formed so as to comprise a plurality of appendages connected at a center so as to improve die forming of the body into a final desired shape while at the same time minimizing stress-induced deformation in the body.Type: GrantFiled: December 20, 2007Date of Patent: March 25, 2014Assignee: Greatbatch Medical S.A.Inventors: André Lechot, Sarah Claude, Philippe Fehlbaum, Patrick White, Didier Guelat

Patent number: 8491586Abstract: Disclosed is a surgical tool holder adapted to connect to a disposable cutting tool, and the surgical instrument combination. The tool holder has a shank with a quick tool coupling at one end and a drive adaptor at a second end. The coupling assembly has a coupling interface for holding the tool, and has a debris reservoir. A locking mechanism is engageable with the shank by a lock interface that holds the coupling assembly in functional assembly, and when unlocked allows component parts of the coupling assembly to be separated for cleaning and sterilization. The surgical tool has a flat base and complementary fittings adapted to be received by the holder's coupling interface. The combination of the flat base with the reservoir defines a relatively enclosed collection space to receive cutting debris from the tool while the holder and tool are coupled together.Type: GrantFiled: February 6, 2008Date of Patent: July 23, 2013Assignee: Greatbatch Medical S.A.Inventors: André Lechot, Yann Rossé, Didier Guélat

Patent number: 8277457Abstract: An orthopedic prosthetic inserter used for the implantation of an acetabular prosthetic cup implant. The inserter consists of a drive train, a C-shaped housing, and a collet mechanism used to attach a prosthetic cup implant. When activated by the drive train, the collet mechanism expands to draw the prosthesis towards the collet mechanism and create a substantially friction tight engagement therebetween.Type: GrantFiled: March 16, 2010Date of Patent: October 2, 2012Assignee: Greatbatch Medical S.A.Inventors: Jonas Burgi, Yves Desarzens, Andre Lechot

Patent number: 8182486Abstract: A reamer system is provided which includes a cannulated reamer handle, and a corresponding cannulated reamer, which, when assembled and operated over a drill pin secured in a manner axially aligned with the stem of the femoral joint, enables the accurate and controlled reshaping of the femoral joint. The reamer is made up of a cutting form and a central guide, in which the guide is supported at the center of the cutting form by a bar structure. The bar structure includes portions which connect to and extend radially between the central guide and a peripheral edge of the cutting form. Optionally, the central guide includes a surface offset from a plane of the bar structure to a degree which enables that surface to contact an associated surface referenced to the bone, in order to prevent the cutting form from plunging so far over the bone as to potentially damage the femoral stem.Type: GrantFiled: October 31, 2007Date of Patent: May 22, 2012Assignee: Greatbatch Medical S.A.Inventors: Yves Desarzens, Andre Lechot

Patent number: 8075563Abstract: Disclosed is a guided orthopedic bone reamer (10a) for cutting a profile relief shape (21a) into a joint bone (20). The reamer (10a) has a cutting head (30a) and an axial guide assembly (70). The cutting head (30a) has a profile cutting form (24a) with a rim (34) and an apex (38a). The apex (38a) connects to the cutting form (24a) by a set of struts (94). An axial guide assembly (70) has one end (44a) fixed to the apex (38a) and at the other end has a bayonet mechanism (76) connectable to a drive handle. Rim cutting teeth (36a) are set into the rim (34) to cut a cylindrical profile (21a), and bevel cutting teeth (96) integral to the struts (94) cut a bevel (25) onto the cylindrical form (21a) cut into the bone (20). A guide pin bore (12a) passes through the apex (38a) and the guide assembly (70) concentric with the axis of rotation (18) to receive a guide pin (14) to guide the reamer (10a) in cutting alignment relative to the joint bone (20) to be cut.Type: GrantFiled: June 16, 2008Date of Patent: December 13, 2011Assignee: Greatbatch Medical S.A.Inventors: Didier Guelat, André Lechot
