A kit of parts for inserting a deformable implant into a cavity in a bone of a patient is described. An inserter instrument comprises a body having a cavity extending along a longitudinal axis from a distal end to a proximal end. An attachment mechanism is provided at the distal end and to which a deformable implant can be releasably attached. A drive mechanism is provided at the proximal end of the body. An insertion stop is mounted on the body and arranged to control the depth of insertion of the inserter instrument into a guide tube. A push rod is freely and slidably arranged within the cavity and has a distal end engageable with a part of the deformable implant and a proximal end abutable by the drive mechanism. The drive mechanism is operable to drive the push rod toward the distal end of the body. The kit also includes an impactor dimensioned for slidable engagement within the cavity.

Implant inserter assembly

A kit of parts for inserting a deformable implant into a cavity in a bone of a patient is described. An inserter instrument () comprises a body () having a cavity extending along a longitudinal axis from a distal end to a proximal end. An attachment mechanism () is provided at the distal end and to which a deformable implant can be releasably attached. A drive mechanism () is provided at the proximal end of the body. A push rod () is freely and slidably arranged within the cavity and has a distal end engageable with a part of the deformable implant and a proximal end abutable by the drive mechanism. The drive mechanism is operable to drive the push rod toward the distal end of the body. The kit also includes an impactor () dimensioned for slidable engagement within the cavity.

Surgical instruments

An orientation guide comprising a housing arranged to couple to a surgical instrument. In one embodiment the orientation guide further comprises first and second indicators (). The first indicator () is pivotally coupled to the housing () such that the first indicator () can rotate relative to the housing () about a first axis () to maintain its angular position about the first axis () relative to a vertical axis irrespective of movement of the housing (). The second indicator () surrounds the first indicator () and is pivotally coupled to the housing () such that the second indicator () can rotate relative to the housing () about a second axis () orthogonal to the first axis () to maintain its angular position about the second axis () relative to the vertical axis irrespective of movement of the housing (). The angular position of the housing () about the first and second axes () is indicated by the position of the first indicator () relative to the second indicator (). In a second embodiment the housing () comprises a cavity filled with a fluid. An indicator () is supported within the fluid such that the indicator () can rotate relative to the housing () about a first axis to maintain its angular position about the first axis relative to a vertical axis irrespective of movement of the housing (). The indicator () comprises a marking arranged to indicate the angular position of the indicator () relative to the housing () about the first axis. The housing () has at least one transparent portion for viewing the marking. A measuring element () is coupled to the housing () and arranged to slide relative to the housing () to be aligned with the indicator marking such that the angular position of the housing () about the first axis can be recorded.

Orientation guide

A support structure implant for location within a bone cavity to support the bone which defines the cavity is formed from wires by braiding in a machine direction from a first end of the structure towards an opposite second end. The wires are formed into loops at the first end of the structure so that two lengths of wire extend away from each loop and a reformed into the braid. Each of the wires which is formed into the braid is held at the second end of the structure in a clamp. The clamp is provided by a support ring and a clamp ring which is formed from a shape memory alloy which can shrink to clamp the wires against the support ring when heated.

Support structure implant for a bone cavity

A support structure implant for location within a bone cavity to support the bone which defines the cavity is formed from interlaced wires which extend from a first end of the structure towards an opposite second end. The wires are formed into loops at the first end of the structure. The structure includes a clip having a plurality of fingers which extend through the loops to control the spacing between the loops.
