Abstract

A surgical clip for connecting at least two bio-organic tissue members together, the clip comprising a body having two spaced legs and formed into a U-shape, each leg having a distal end which can be inserted into an opening in bone and each having a proximal end, the proximal ends of said at least two legs being connected to corresponding ends of a deformable bridge comprising two spaced apart bridge sections with a gap disposed between the bridge sections, the bridge sections being deformable by a force, the gap being changed by the force to cause the two spaced legs to move into engagement with side walls of the openings in the bone to which the clip is connected, the body comprising the at least two spaced legs and the two bridge sections comprising a single piece of material.

Claims

1. A surgical clip for connecting at least two bio-organic tissue members together, the clip comprising a body having two spaced legs and formed into a U-shape, each leg being substantially straight, each leg having a distal end which can be inserted into an opening in a bio-organic tissue member and each having a proximal end, the proximal ends of said at least two legs being connected to corresponding ends of a deformable bridge coupling the at least two legs together, the bridge comprising two spaced apart bridge sections with a gap disposed between the bridge sections, the bridge sections having a non-deformed condition and a deformed condition, the bridge sections being deformable by a force such that once the bridge sections are deformed, the bridge sections remain in the deformed condition and do not automatically return back to the non-deformed condition, the gap being changed by the force to cause the two spaced legs to move, when the clip is inserted into the two bio-organic tissue members, into secure engagement with side walls of the openings in the bio-organic tissue members to which the clip is connected, the body comprising the at least two spaced legs and the two bridge sections comprising a single piece of material, the legs remaining substantially straight after insertion into the bio-organic tissue members, with distal portions of the spaced legs moving closer together than proximal portions of the spaced legs when the gap between the bridge sections is increased, thereby securely holding the two tissue members together;

further comprising a wing member extending transversely from each end of the bridge, each wing member having apertures therein for receiving a screw for fastening the clip member to a bio-organic tissue member.

2. A method for connecting at least two bio-organic tissue members together, one of the members comprising a soft tissue member and the other member comprising a bone part, the method comprising:

forming at least two openings in the bone part;

providing a clip having a U-shape with two legs extending distally and a deformable bridge between the two legs, the bridge comprising two spaced apart bridge sections with a gap disposed between the bridge sections, the bridge sections being deformable by a force, the legs having a length extending distally;

inserting the at least two legs into respective openings in the bone part for only a portion of the length of the legs;

providing the soft tissue member beneath the bridge sections between the bridge sections and the bone part;

driving the clip completely into the bone part so that the soft tissue member is secured between the bridge sections and the bone part; and

deforming the bridge by changing the spacing between the bridge sections to cause the two spaced legs to move into engagement with side walls of the openings in the bone to which the clip is connected.

3. The method of claim 2, further comprising increasing the spacing between the bridge sections to cause the two spaced legs to move towards each other thereby to secure the clip in the bone part.

4. The method of claim 2 further comprising the step of decreasing the spacing between the bridge sections to cause the legs to move apart thereby to secure the clip in the bone part.

5. The method of claim 2, further comprising providing serrations on each leg to enable the legs to be secured into the bone part.

6. The method of claim 2, further comprising providing the serrations on the legs facing each other.

7. The method of claim 2, further comprising providing the serrations on each leg facing away from each other.

8. The method of claim 3, further comprising providing serrations on each leg facing each other to enable the legs to be secured into the bone part.

9. The method of claim 4, further comprising providing serrations on each leg facing away from each other to enable the legs to be secured to the bone part.

10. A method for connecting at least two bio-organic tissue members together, one of the members comprising a soft tissue member and the other member comprising a bone part, the method comprising:

forming at least two openings in the bone part;

providing a clip having a U-shape with two legs extending distally and a deformable bridge between the two legs, the bridge comprising two spaced apart bridge sections with a gap disposed between the bridge sections, the bridge sections being deformable by a force, the legs having a length extending distally;

inserting the at least two legs into respective openings in the bone part for only a portion of the length of the legs;

providing the soft tissue member beneath the bridge sections between the bridge sections and the bone part;

driving the clip completely into the bone part so that the soft tissue member is secured between the bridge sections and the bone part; and

deforming the bridge by changing the spacing between the bridge sections to cause the two spaced legs to move into engagement with side walls of the openings in the bone to which the clip is connected;

further comprising providing planar members extending transversely from ends of the bridge and providing an aperture in each of the planar members through which a screw is received for further securing the clip to the bone part.

11. A method for connecting at least two bio-organic tissue members together, one of the members comprising a soft tissue member and the other member comprising a bone part, the method comprising:

forming at least two openings in the bone part;

providing a clip having a U-shape with two legs extending distally and a deformable bridge between the two legs, the bridge comprising two spaced apart bridge sections with a gap disposed between the bridge sections, the bridge sections being deformable by a force, the legs having a length extending distally;

inserting the at least two legs into respective openings in the bone part for only a portion of the length of the legs;

providing the soft tissue member beneath the bridge sections between the bridge sections and the bone part;

driving the clip completely into the bone part so that the soft tissue member is secured between the bridge sections and the bone part;

deforming the bridge by changing the spacing between the bridge sections to cause the two spaced legs to move into engagement with side walls of the openings in the bone to which the clip is connected; and

further comprising providing members extending transversely from ends of the bridge and providing an aperture in each of the members through which a screw is received for further securing the clip to the bone part.
