Abstract

A retention suture is looped around an incision in a deep tissue layer such as the muscle layer, with the ends of the suture being passed up through a tubular retention suture device. The device is emplaced in the incision and the ends of the retention suture are drawn up tightly and secured at the top end of the device. The incision is closed between the retention suture devices by the primary wound closure sutures, and these devices remain in the incision until healing of the muscle tissue layer is adequate.

Claims

1. A device insertable in a surgical incision for use with a rentention suture which is looped around an incision in a deep tissue layer comprising:

a. an elongate hollow tube adapted to be inserted into said surgical incision above said deep tissue layer, said tube having a bottom end and a top end, the bore of said tube being sufficiently large to receive the two end portions of said suture therethrough; and

b. means at the top end of said tube for retaining said end portions of said suture and preventing same from being retracted through said tube.

2. The device as specified in claim 1 wherein said means for retaining said end portions of said suture comprises an element extending across the bore of said tube at the top end of said tube to allow said end portions of said suture to be tied together over said element.

3. The device as specified in claim 2 wherein said element extends substantially the length of said tube to divide the bore of said tube into two passageways each sufficiently large to receive one end portion of said suture therethrough.

4. The device as specified in claim 1 wherein said means for retaining the end portions of said suture comprises a support member placed transversely over the top end of said tube in position to allow the end portions of said suture to be tied together over said support member.

5. The device as speciFied in claim 4 wherein the top end of said tube has flared portions in two opposed directions and grooved portions substantially at right angles to said flared portions, said support member fitting into said grooved portions.

6. The device as specified in claim 5 wherein said support member has flared ends.

7. The device as specified in claim 1 wherein the bttom end of said tube is flared out in two opposed directions.

8. The device as specified in claim 1 wherein the bottom end of said tube is flared around the circumference thereof.

9. A method of suturing a surgical incision particularly that portion of said incicsion in deep body tissue comprising the steps of:

a. encircling the suture around said incision in said deep body tissue;

b. passing the end portions of said suture through a hollow tube;

c. inserting said tube into the incision above said deep body tissue; and

d. securing said end portions of said suture at the top end of said tube.
