A femoral head guide clamp can include jaws and two opposing arms that extend from the jaws. The jaws can include an aperture shaped such that the jaws have a closed position in which the aperture fits around a femoral neck of a patient but is too small to accept a femoral head of a patient, and an open position in which the aperture is expanded such that it is large enough to allow the femoral head to pass through. The arms can include a proximal section in which the arms are substantially parallel in a side-by-side arrangement, and a distal section in which the arms extend away from each other such that moving the two distal sections towards each other moves the jaws towards the open position.

Guide for positioning a resurfacing head implant

An acetabular cup guide can include a distal end () shaped to allow removable connection to a surgical instrument (), a proximal end including one or more contact surfaces () shaped to conform to an acetabulum, and a central proximal-distal axis extending through the acetabular cup guide. At least one of the one or more contact surfaces can be configured such that it is deflectable towards the central proximal-distal axis in order to reduce an axial cross-section of the acetabular cup guide.

Hip cup alignment guide

The present invention relates to a guide for positioning a resurfacing head implant into the appropriate position and angles on the femur bone. The present invention therefore provides a guide system for an implantable device (e.g. a resurfacing head implant), said guide system comprising a first component arranged to act as a clamp and a second component arranged to interact with the first component to prevent movement of said first component when clamped.

A rotary cutter with hemispherical shaped head and a plurality of blades mounted in said head, wherein each of said blades has securement means for securing each blade in position in said head by interacting with an inner surface of said head.

Rotary cutter for preparing the acetabular socket for a hip implant

The present invention is directed to a system comprising a medical instrument (e.g. cup implant,) and a holding device () that interacts with said medical instrument to form a sealable cavity within the combined arrangement of components. An impaction device () is also provided, preferably which provides means to allow fluid to be expelled from the cavity but which prevents further fluid from entering the cavity.

Holder for an acetabular cup implant

A holder system for an implantable device, said holder system comprising a first component arranged to act as a clamp and a second component arranged to interact with the first component to prevent movement of said first component when clamped.

Holder for resurfacing head implant

The present invention provides a cup positioning guide which has a mechanical link from a cup introducer connection distal to the hip socket, to one or more landmarks on the pelvis. It facilitates intra-operative checks and adjustments to be made to reamed hip socket depth, cup anteversion and cup rotation with the aid of a cup trial component.

A device () for aligning a guide wire with a bone, comprising: an attachment means () reversibly attachable to a bone; an alignment means () connected to the attachment means, the alignment means being moveable so as to locate a portion of the bone for insertion of the guide wire. A method for aligning a guide wire with a bone.

Medical aligning device

An autoinjector includes a rear body assembly () connected to a front body assembly, wherein the rear body assembly () contains a drive mechanism (. . . ) and the front body assembly contains a syringe () or cartridge with a needle at its forward end, the front body assembly including a viewing window () through which at least part of the contents of the syringe () or cartridge are visible, a removable cap () fitted to the forward end of the front body assembly the rear body assembly and the removable cap having respective aligned cut-away regions together defining a frame for the viewing window. Also disclosed is a modular scheme which uses a common platform for the provision of a range of autoinjectors of different fill volumes, with only the length of the plunger (), and the axial extent of the cut out varying between different versions.

Autoinjectors

An injection apparatus includes a counter wheel that is incremented by the dose delivery mechanism each time the device is fired. The apparatus includes a final dose disabling mechanism that prevents further usage once the final dose has been delivered. An anti-tamper feature is provided to prevent inadvertent or premature initialisation of the apparatus.

Injection apparatus

An autoinjector includes a body (), a syringe () or cartridge disposed within the body, and a plunger () moveable during operation between a first and a second position to effect an injection, the plunger including a transverse passage () containing a moveable magnetic element () of a magnetic pair, the body including another magnetic element () at a position such that, on the plunger reaching and/or nearing its second position, the magnetic attraction therebetween causes a sound-emitting impact, the plunger () including a magnetic keeper element () mounted adjacent the transverse passage and adapted to hold the movable magnetic element () against movement until attraction by the other magnetic pair element (), wherein the keeper element () is disposed on the longitudinal axis.

An autoinjector has a main body () containing a syringe () or cartridge with a needle at its front end for being moved forwardly in the body to extend the needle from the body for an injection, the body housing in a forward region a shroud () having a forward portion of generally tubular form (32), the shroud being moveable longitudinally between a rearward retracted position and a forward extended position, the autoinjector further including a spring arrangement for biasing the shroud forwardly, the spring arrangement () including two springs disposed alongside and spaced from the longitudinal axis.

An autoinjector has a body portion () containing a syringe () or cartridge with a needle at its forward end, the autoinjector having a drive arrangement (. . . ) for effecting operation of the autoinjector and including a drive element that moves from a first position to a second position during the operation, the body including a first () and a second body portion () connected together by a snap fit arrangement including a resiliently moveable latch finger () on one of the body portions that cooperates with a latch surface () on the other thereof to hold the two portions connected, wherein the drive element in the second position () limits or prevents resilient movement of the moveable latch finger (), thereby preventing disconnection of the first and second body portions after operation.

Autoinjector with means for preventing reuse and disconnection of said first and second body portions after operation

A method of locating an acetabular cup implant () in a pelvis comprises locating a plurality of reference points on the pelvis, defining a target location of the implant relative to the reference points, and placing the implant at the target location. A method of locating a femoral head implant () is also disclosed, together with associated guidance systems.
