An inclination guide for use with an implant insertion tool during a surgical procedure includes a unitary body having a clip configured to be coupled to a mounting surface of the implant insertion tool, an elongated riser extending from the clip, and an elongated indicator extending from the elongated riser to a distal end. Such a design allows for an inexpensive and lightweight inclination guide that may be easily and quickly adjusted after assembly.

Removable inclination guide for an implant insertion tool and associated surgical method

Inclination guide

A surgical rotational tool driver and method. The driver includes a driveline extending within a hollow shaft and a head part including connection features for connecting to a connection member of a surgical rotational tool. The connection features of the head part include a housing and a pair of jaw member each including jaws for receiving the connection member. Each jaw member is pivotally mounted for rotation between: a first position for receipt of the connection member and a second position for retaining the connection member. The connection features of the head part further include a locking mechanism including a pair of catches for engaging with a respective catch of each jaw member to lock the jaw members in the second position. The locking mechanism also includes a release member slideably moveable within the housing to release the catches of the locking mechanism from the catches of the jaw members.

Surgical rotational tool driver and method

A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion. The surgical component also includes an elongate stem for inserting into an intramedullary canal of a patient. The elongate stem extends distally from the body portion. The elongate stem has a longitudinal axis; a proximal end; a distal end; and a plurality of splines located on an outer surface of the stem. The splines are circumferentially arranged around the stem. At least some of the splines are tapered such that each tapered spline is narrower at a distal part of that spline than at a part of that spline that is proximal with respect to the distal part. The surgical component further includes an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.

Surgical component, kit and method

The invention provides a reamer handle comprising: a shank having a distal tool coupling end adapted to releasably couple to a part of a surgical tool and a proximal end; a retractable catch which is linearly displaceable along the shank between a non-retracted position in which the catch captures the surgical tool within the distal tool coupling end of the tool holder and a retracted position in which the catch enables the tool to be released from the distal tool coupling end; a biasing member configured to bias the catch in the non-retracted position; and a sleeve extending along the shank. The sleeve comprises: a distally located catch contacting portion and a proximally located handle portion for manually displacing the sleeve relative to the shank such that displacement of the catch contacting portion moves the retractable catch between the non-retracted position and the retracted position to enable capture and release of the tool from the tool holder.

Surgical tool release mechanism

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.

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

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.
