Abstract

A device for limiting a force applied by a tool to a target object, the adaptor comprising a first part, and a deformable member arranged to contact the first part and deform upon application of the force by the tool to the device. The first part and the deformable member are arranged to define a load path between first and second sides of the device. The deformable member is configured to deform when the force through the load path is above a first pre-determined level, thereby absorbing a first amount of the force, so as to impart a resultant force to the target object no greater than the first pre-determined level.

Claims (18)

1. A device for limiting a force applied by a tool to a target object, the device comprising: a first part, and a deformable member arranged to contact the first part and deform upon application of the force by the tool to the device, wherein the first part and the deformable member are arranged to define a load path between first and second sides of the device, wherein the deformable member is configured to deform when the force through the load path is above a first pre-determined level, thereby absorbing a first amount of the force, so as to impart a resultant force to the target object no greater than the first pre-determined level.
2. A device according to claim 1 further comprising a visual indicator configured to display information indicative of a state of the deformable member.
3. A device according to claim 2, wherein the visual indicator comprises at least one surface feature disposed on a surface of the device, and wherein the at least one surface feature is indicative of the height of the deformable member.
4. A device according to claim 3, wherein the visual indicator comprises a slotted section in a side wall of the first part, wherein the at least one surface feature comprises at least one protrusion extending away from the surface of the device and into the slotted section, and wherein the first part comprises an outer surface having at least one surface feature indicative of the height of the deformable member.
5. A device according to any preceding claim, wherein the tool comprises an impactor head having a distal end and the device comprises an attachment for mounting on the impactor head, such that when so mounted the deformable member is secured to the distal end of the impactor head.
6. A device according to any of claims 1 to 4, wherein the device is comprised within an impactor head of the tool.
7. A device according to any preceding claim, wherein at least a first section of the deformable member is configured to plastically deform when the force is greater than the first pre-determined level.
8. A device according to any preceding claim, wherein the deformable member comprises a lattice structure or a foam region.
9. A device according to any preceding claim, wherein the deformable member is separable from the first part.
10. A device according to any preceding claim, wherein the deformable member comprises any of a plastic or a metal material.
11. A device according to any preceding claim comprising at least one frangible member in the load path, wherein the frangible member is configured to break when the load exceeds a second pre-determined level, and wherein, in use, breaking the frangible member provides visual, audible and/or haptic feedback.
12. A device according to claim 1 1 , wherein the second pre-determined level is less than the first pre-determined level.
13. A device according to claim 11 or claim 12, wherein the frangible member is connected to the first part by a first connection, and wherein the first connection is configured to break when the load exceeds the second pre-determined level.
14. A device according to any preceding claim, wherein the first side is located on the first part and is arranged to contact the target surface.
15. A device according to any preceding claim further comprising a second part configured to move relative to the first part upon application of the force by the tool, wherein the second side is located on the second part, and wherein the deformable member is disposed between the first part and the second part.
16. A method of impacting a target object, comprising: providing a device according to any preceding claim, placing the first side of the device against the target object, and impacting the second side with a force up to or exceeding the first predetermined level, resulting in the application of a force no greater than the first pre- determined level to the target object.
17. A method according to claim 16 or a device according to any of claims 1 to 15, wherein the target object is a prosthetic component.
18. A kit of parts comprising a device according to any of claims 1 to 15 and instructions to carry out a method according to claim 16 or claim 17.
