Abstract

A supporting element for a staple region suitable for application by an automatic stapling device employed during surgery. The supporting element comprises a fabric-like object having a tube-like shape, the supporting element in one end having a narrowed opening formed by stitching up with sewing yarn.

Claims

1. A supporting element for staple region comprising a fabric-like object having a tube-like shape with two open ends, said supporting element in one end having a narrowed opening formed by stitching up that open end with sewing yarn.

2. A tube-like supporting element for staple region according to claim 1 comprising a fabric-like object made of biodegradable and bioabsorbable material integrated with stretchable textile at both ends.

3. The tube-like supporting element for staple region according to claim 2 wherein said material and said textile are integrated with sewing yarn in plain stitch and ends of the sewing yarn extend to the exterior of the supporting element.

4. The tube-like supporting element for staple region according to claim 2 wherein said biodegradable and bioabsorbable material is at least one selected from the group consisting of polyglycolic acid, polylactic acid, copolymer of polyglycolic acid and polylactic acid, mixture of polyglycolic acid and polylactic acid, para-dioxanone, polycaprolactone and chitin.

5. A tube-like supporting element for staple region according to claim 2 wherein stretchable textile is stretch warp knit.

6. A tube-like supporting element for staple region according to claim 2 wherein said unwoven fabric is made of polyglycolic acid.

8. A method for cutting an affected part comprising the steps of;

(1) fitting tube-like supporting elements for staple region according to claim 6 on frame section and staple built-in-type cartridge section respectively;

(2) sandwiching a disordered tissue in the body having an affected part and a normal part between the frame section and the cartridge section;

(3) integrating the tissue and the fabric-like object made of biodegradable and bioabsorbable material; and

(4) separating the affected part from the normal part.

7. A method for cutting an affected part comprising the steps of;

(1) fitting tube-like supporting elements for staple region comprising a fabric-like object having a tube-like shape on frame section and staple built-in-type cartridge section respectively;

(2) sandwiching a disordered tissue in the body having affected part and normal part between the frame section and the cartridge section;

(3) integrating the tissue with the fabric-like object made of biodegradable and bioabsorbable material;

(4) separating an affected part from a normal part; and

(5) removing stretchable textile.
