Device and a method for use in transplantation of bone tissue material
First Claim
1. A device for use in transplantation of bone tissue material in a cavity of a bone so as to give the cavity a desired shape with a required thickness of the bone material forming a wall of the cavity, said device comprising:
- means for compacting the bone tissue material in the cavity,a guide pin for fixed engagement to said bone substantially centrally in the cavity,said compacting means having an opening for passage of the guide pin,said guide pin guiding sliding movement of the compacting means within said cavity when said guide pin is engaged to said bone,wherein the compacting means has a jacket to compact the bone material,said jacket delimiting an inner hollow space and having a plurality of openings to allow liquid to pass through the jacket and into the hollow space when compacting the bone material.

Abstract
A device and a method for use in transplantation of bone tissue material in a cavity (7) in bones (6) so as to give the cavity a desired shape with a required thickness of the bone material forming the wall of the cavity, is based on the use of a means (3) for compacting the bone tissue material (15) in the cavity. A guide pin (1) is adapted to be applied substantially centrally in the cavity (7). The compacting means (3) has an opening (10) for passage of the guide pin (1) so as to obtain guiding of the compacting means by the guide pin on movement of said means with respect thereto. The compacting means (3) has a jacket (12) delimiting an inner hollow space (13). The jacket (12) is provided with an opening (16) for allowing liquid to pass through the jacket and into the hollow space.

8. A device for use in transplantation of bone tissue in a cavity of a bone so as to give the cavity a desired shape with a required thickness of the bone material forming a wall of the cavity, said device comprising means for compacting the bone tissue material in the cavity, wherein the compacting means has a jacket to compact the bone material, said jacket delimiting an inner hollow space and having openings to allow liquid from the surrounding bone tissue material to pass through the jacket and into the hollow space.

9. A method for use in transplantation of bone tissue material in a cavity of a bone so as to give the cavity a desired shape with a required thickness of the bone material forming a wall of the cavity, said bone tissue material being compacted in the cavity against remaining bone material by means of a compacting means, wherein during compacting liquid from the surrounding bone tissue material is allowed to flow into an inner hollow space delimited by a jacket of the compacting means through openings in the jacket wherein liquid contained within said hollow space can thereafter be removed.
