Abstract: An apparatus and methods for guiding the orientation of an item of surgical equipment relative to a limb of a patient are described. A reference orientation sensor operable to determine a reference orientation has a first attachment feature for attaching to a limb of a patient. A surgical equipment orientation sensor operable to determine a surgical equipment orientation has a second attachment feature for attaching to an item of surgical equipment. A data processing apparatus: determines and stores an initial relative orientation between the reference orientation sensor and the surgical equipment orientation sensor from an initial reference orientation and an initial surgical equipment orientation; determines a current relative orientation between the reference orientation sensor and the surgical equipment sensor from a current reference orientation and a current surgical equipment orientation; and generates an output signal when the current relative orientation matches the reference relative orientation indicating that the surgical equipment orientation sensor currently has the same orientation relative to the reference orientation sensor as when the initial relative orientation was determined.

Abstract: A trial liner for fitting in a shell part of an orthopaedic joint prosthesis has a concave inner bearing surface for articulation with a head part, and an opposite outer surface. The liner has first and second portions which are separated by a slot extending between the inner and outer surfaces which has first and second ends. The slot divides the liner into first and second portions which are connected to one another by means of a first hinge at the first end of the slot and a second hinge at the second end of the slot. Each of the first and second portions has a locking feature in the form of a recess or protrusion which can engage a corresponding locking feature on the internal surface of a shell part to lock the liner into the shell part. The hinges allow the first portion of the liner to pivot relative to the second portion between first and second configurations, in which the distance between the first and second portions is less in the second configuration than in the first configuration.

Abstract: An acetabular reamer handle and a method of reaming an acetabulum. The handle includes a hollow shaft having a plurality of shaft sections including a distal shaft section having a distal end and a proximal end and an additional shaft section having a distal end that is pivotally attached to the proximal end of the distal shaft section to allow the additional shaft section and the distal shaft section to be adjustably oriented at an angle. The handle also includes a hollow neck part having a longitudinal axis. The handle further includes a drive line having a head part mounted for rotation about the longitudinal axis and connectable to a reamer. A distal end of the distal shaft section is pivotally attached to a proximal end of the neck part to allow the distal shaft section and the neck part to be adjustably oriented at an angle.

Abstract: An acetabular reamer handle including a shaft having a distal end, a neck part having a longitudinal axis, a driveline extending through the shaft and the neck part, and a locking mechanism. A distally located head part of the driveline is mounted for rotation about the longitudinal axis of the neck part and is connectable to a reamer. The distal end of the shaft and a proximal end of the neck part are pivotally attached to allow the shaft to be tilted relative to the longitudinal axis. The tilting can allow part of the acetabulum and/or reamer that is otherwise obscured to be viewed. The locking mechanism includes an engagement member having an engagement surface located at the distal end of the shaft. The engagement member is moveable distally to urge the engagement surface against the proximal end of the neck part.

Abstract: A connection member for connecting a surgical tool to a plurality of different kinds of corresponding connector. A surgical tool including the connection member. A surgical kit including the surgical tool. The connection member includes an elongate shaft having a longitudinal axis, a proximal end and a distal end. The connection member also includes a plurality of connection features located at the proximal end of the shaft. The plurality of connection features includes at least one connection feature for mating with a first kind of corresponding connector. The plurality of connection features also includes at least one connection feature for mating with a second, different kind of corresponding connector. The connection member may be a male connection member and the corresponding connectors may be female. A method including providing the surgical tool and connecting the connection member to a corresponding connector.
